DETAILED DESCRIPTION OF THE INVENTION
(11) Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present invention.
(12) Within the scope of the present description, the reference to an embodiment or the embodiment or some embodiments means that a particular feature, structure, or element described with reference to an embodiment is comprised in at least one embodiment of the described object. The sentences in an embodiment, in the embodiment, or in some embodiments in the description do not, therefore, necessarily refer to the same embodiment or embodiments. The features, structures, or elements can be furthermore combined in any adequate way in one or more embodiments.
(13) Within the scope of the present invention, input materials include glass, rocks, quarries, ceramics, plastics, other recyclable materials, and the combination thereof to be grinded and processed later.
(14) The present invention provides a glass grinder and a method of grinding input materials designed to (1) prevent structural damage due to large, hard, and uncrushable materials, and (2) change the size (diameter) and smooth out the sharp edges of the grinded materials.
(15) Now referring to FIG. 1, an overview diagram showing the housing of a glass grinder 100 in accordance with an exemplary embodiment of the present invention is illustrated. Glass grinder 100 includes a compression chamber 101 removably stacked on top of an output container 110. Input materials such as glass, quarries, ceramic, plastics, or rocks are input into an input opening 102. The input materials are grinded in compression chamber 101 and collected in output container 110. A pair of handles 111, located on both sides of output container 110, is designed to facilitate the carrying and handling of output container 110. A power button 103 is in electrical communication with a motor (not shown). A light emitting diodes (LED) 105 is designed to inform the operations and/or problems with glass grinder 100. In various preferred embodiments of the present invention, LED 105 is lit when the motor is in a safety mode operation. The safe mode operation avoids structural damage to glass grinder 100 when the input materials are too hard and too large to be grinded. The electrical circuits that controls the operations of LED 105 power button 103 are well known in the art and will not be discussed herein. In some embodiments of the present invention, the size of the output materials can be changed either by replacing or adjusting size adjustment knobs 107. In some other embodiments, pair of size adjustment knobs 107 are used to adjust the size of the output materials by moving them horizontally back and forth.
(16) Next, referring to FIG. 2A-FIG. 2C, FIG. 2A shows a two-dimension (2D) front diagram showing the internal structure and a motor 273, FIG. 2B shows a 2D lateral diagram, and FIG. 2C shows a 3D oblique view of the internal components of compression chamber 101. Together FIG. 2A-FIG. 2C are present to show the manner the principal components of compression chamber 101 are connected together to accomplish the objectives of the present invention.
(17) In many various aspects of the present invention, compression chamber 101 includes a movable crushing jaw 203 equipped with a first section 201 and a second section 202. First section 201 and second section 202 have different slopes (angles or gradients) relative to a fixed vertical crushing jaw (see FIG. 3). In other words, first section 201 forms a different angle than that of second section 202 with respect to fixed vertical crushing jaw. At the back of movable crushing jaw 203, a toggle bar 211 is connected between movable crushing jaw 203 and first adjusting structure 221. A second adjusting structure 231 has a trapezoid shape and is positioned to slide on a slanted surface 223 of first adjusting structure 221. One side of second adjusting structure 231 is connected to a safety spring 241 which is inserted into a safety spring rod 242. The top end of safety spring rod 242 is fixedly fastened to compression chamber 101 by a lead screw 243. Referring to FIG. 200B, first adjusting structure 221, second adjusting structure 231, and safety spring 241 are arranged in a reversed L-shaped configuration to the right hand side of movable crushing jaw 203. The front of first adjusting structure 211 is connected movable crushing jaw 203 by toggle bar 211. FIG. 200A and FIG. 200C show a pair of fly wheels 251-252 coupled to a pair of driving wheels 253-254 via a pair of V belts 255-256. FIG. 200A and FIG. 200C show that movable crushing jaw 203 is attached to a corrugated plate 208 that forms an angle with fixed vertical crushing jaw and a granular plate 209 that is parallel to the fixed vertical jaw.
(18) Referring again to FIG. 200A, pair of driving wheels 253-254 are connected by a main axle 259 which is connected to motor 273 by a spiral bevel gear set 271-272-270. Spiral bevel gear set 270 includes a ring 271 in gear communication with a pinion 272. As motor 273 is turned on and rotates, ring gear 271 is rotated. Ring gear 271 causes pinion 272 to rotate, which in turn, causes main axle 259 to rotate. The rotation of main axle 259 causes pair of driving wheels 253-254 to rotate. Pair of V belts 255-256 pulls to rotate pair of fly wheels 251-252.
(19) Now referring to FIG. 3, a 2D diagram of a compression chamber 300 that illustrates the operation principle of glass grinder 100 in accordance with an exemplary embodiment of the present invention. FIG. 3 shows movable crushing jaw 203 includes first section 201 and second section 202. First section 201 has a length L, and is affixed with corrugated plate 208. First section 201 and corrugated plate 208 are designed to form an angle @ with a fixed vertical crushing jaw 204. Second section 202 has a length h and is equipped with granular surface 209. Second section 202 and granular plate 209 are parallel to fixed vertical crushing jaw 204. This overall arrangement has the shape of a half funnel. Second section 202 and fixed vertical crushing jaw 204 are parallel to the Y-axis of a XYZ coordinate 399. The distance between granular surface 209 and fixed vertical crushing jaw 204 is d. Distance d can be changed to output various output sizes of the input materials. A size adjustment key 222 is used to vary the distance d. In some preferred embodiments of the invention, if the length of size adjustment key 222 is 53 cm, then the distance d is 3 cm. When the length of adjustment key 222 is 65 cm, the distance d is 10 cm. FIG. 3 also shows that movable crushing jaw 203 includes a slot 213 arranged in the Y-direction. Slot 213 is mated with a nut 212 of toggle bar 211 that connects movable crushing jaw 203 with first adjustment structure 221. Nut 212 is allowed to slide up and down slot 213. First adjustment structure 221 includes slanted slide 223 on which second adjustment structure 231 slides up and down.
(20) In operation, as motor 273 is turned on, input materials are input to the half funnel shape formed by first section 201 and fixed vertical crushing jaw 204. As shown above, during normal operation, when motor 273 is rotated, cylindrical spiral bevel gear set 270 causes pair of driving wheels 253-254 to rotate. Consequently, pair of V belts 255-256 causes pair of fly wheels 251-252 to rotate in a first direction 301. This causes movable crushing jaw 203 to move in both Y-direction and Z-direction against fixed vertical crushing jaw 204. In various aspects of the present invention, the movement in the Y-direction is substantially less than the Z-direction. This is indicated as a direction 302. The length h of second section 202 is designed to smooth out sharp edges of the grinded input materials. This motion causes header 212 to move up and down slot 213, depending on the diameter of the input materials. As such, toggle bar 311 thrusts first adjustment structure 221 along the X-direction in a direction 303. At the same time, second adjustment structure 231 slides up and down along slanted surface 223 in a direction 304. Finally, vertical spring 241 moves up and down along vertical rod 242 in a direction 305. With this operation, input materials such as glass, rocks, ceramics, quarries, plastics, recycles, and the combination thereof having a diameter larger than the angle @ are grinded and smoothed out by corrugated plate 208, granular plate 209, and fixed vertical crushing jaw 204.
(21) Next, referring to FIG. 4A-FIG. 4B, two different modes of operations of glass grinder 100 are illustrated. In FIG. 4A, a two dimension (2D) diagram 400A illustrates the normal mode operation of glass grinder 100 when the input materials are crushable. In FIG. 4B, a two dimension (2D) diagram 400B illustrates the safe mode operation of glass grinder 100 when the input materials are hard and uncrushable. In other words, FIG. 4A illustrates glass grinder 100 in the normal mode, and FIG. 4B illustrates glass grinder 100 in the safe mode. In the normal mode, first adjustment structure 221, second adjustment structure 231, and safety spring 241 cause movable crushing jaw 203 to operate smoothly, which causes glass grinder 100 to operate smoothly. However, in the safe mode, first adjustment structure 221, second adjustment structure 231, and safety spring 241 cause movable crushing jaw 203 to slide and lock up in order to avoid structure damage to glass grinder 100.
(22) Now referring again to FIG. 3 and FIG. 4A, input materials 411 are input into the funnel shaped mouth (via input opening 102) formed by movable crushing jaw 203 and fixed vertical crushing jaw 204. As motor 273 in a motor housing 120 is turned on by power button 103, spiral bevel gear set 270 causes pair of driving wheels 253-254 to rotate. Consequently, pair of V belts 255-256 causes pair of fly wheels 251-252 to rotate in direction 301. This causes movable jaw 203 to move in both Y-direction and Z-direction in direction 302 with respect to fixed vertical crushing jaw 204. In direction 302 the movement along the Z direction is substantially larger than that in the Y-direction. This motion in direction 302 causes nut 212 to move up and down slot 213, depending on the radius of the input materials 411. As such, toggle bar 311 thrusts first adjustment structure 221 along X-direction 303 of an XYZ coordinate 399. At the same time, second adjustment structure 231 slides up and down along slanted surface 223 in direction 304. Finally, safety spring 241 wiggles up and down along safety spring rod 242 in Y-direction 305. In this normal operation, input materials 411 such as glass, ceramics, rocks, plastics, quarries or other recycle materials having a diameter larger than angle @ are grinded and smoothed out by granular plate 209 and rough surface 215 affixed to fixed vertical crushing jaw 204. In many preferred aspects of the present invention, input materials 411 are glass, then final materials 413 smaller and smoother cullet.
(23) Next, FIG. 4B illustrates the safe operation mode that prevents stress and structural damage to glass grinder 100. When input materials 421 are large and hard that is cannot be grinded by glass grinder 100, they exert a third Newtonian force 401 that causes movable crushing jaw 203 to slide in the X-direction of XYZ coordinate 499. Movable crushing jaw 203 then transfers a force 402 to push first adjustment structure 221 in the same X-direction 402. As such, second adjustment structure 231 is forced to slide upward along slanted surface 223 by a force 403. This compresses and holds safety spring 241 by a vertical force 404. In this safety mode, unnecessary stress and structural damage to glass grinder 100 are avoided. Next, if input materials 421 are removed, then forces 404, 403, 402, and 401 vanish, safety spring 241 returns to its original length and shape, second adjustment structure 231 slides downhill on slanted surface 223. This pushes first adjustment structure 221 to the left, return grinder 100 to its normal operation as described in FIG. 4A.
(24) Next, referring to FIG. 5, an assembly diagram 500 showing main components and the manner slider 100 is assembled in accordance with an exemplary embodiment of the present invention is illustrated. First, all required components described above are obtained with screw holes 551 for assembling together. In various preferred embodiments of the present invention, in the first step, components along an X-direction of an XYZ coordinate system 599 are assembled first. Fixed vertical crushing jaw 204, first section 201, second section 202, movable crushing jaw 203, first adjustment block 221 with distance adjustment key 222 and slanted surface 223, second adjustment block 231 with key 232 and safety spring rod 242 are assembled. Next, components arranged along the Z-direction are assembled. Eccentric shaft 516 is inserted into movable crushing jaw 203. Then, a pair of cushion rings 511, a pair of holding flanges 512, a pair of ring locks 513, a pair of washers 514, and a pair of ball bearings 515 are inserted to eccentric shaft 516. Eccentric shaft 516 is inserted into a pair of eccentric shaft through holes 509. Next, main axle 259 as shown in FIG. 2 is inserted into a pair of driving shaft through holes 506 and coupled to pair of driving wheels 253-254. Spiral bevel gear set 270 is coupled to main axle 259 as shown in FIG. 2. Pair of V-belts 255-256 is coupled to pair of fly wheels 251-252 and pair of driving wheels 253-254. In the Y-direction, safety spring 241 is inserted to safety spring rod 242. Motor 273 is secured to pinion 271. Finally, compression chamber first wall 501, compression chamber second wall with a key lock 503, a third compressing wall 504 with a key lock 505, and a fourth compression chamber wall 507 with a key lock 508 are secured to form housing 101. Screw holes 551 are used with securing means such as nails, screws, bolts, connectors, pins, staples, dowels, ball lock, friction lock, threaded fasteners, nuts, etc.
(25) In many embodiments of the present invention, these components are made of metallic plates, heavy duty steel plates, NiCr alloyed cast iron, etc.
(26) Next referring to both FIG. 6 and FIG. 7A-FIG. 7B, diagrams illustrate an exemplary embodiment and the operations of size adjustment key 222. In FIG. 6, a top view diagram 600 of compression chamber 101 showing the location of size adjustment key 222 is illustrated. Front wall 501, back wall 502, side walls 504 and 507 form the casing for compression chamber 101. From top to bottom of FIG. 6, fixed vertical crushing jaw 204 is affixed to front wall 501. At distance d away from fixed vertical crushing jaw 204, moving crushing jaw 203 is connected to toggle bars 211 and then to size adjustment key 222. Size adjustment key 222 and telescopic length adjustment unit 700 are connected to both sides of second adjustment structure 221 which includes slanted surface 223. Second adjustment structure 231 is designed to slide on slanted surface 223 to ease the counter forces of hard and uncrushable input materials. On top of second adjustment structure 231, safety spring 241 and safety spring rod 242 are located.
(27) In FIG. 7A-FIG. 7B, an exemplary structure of telescopic length adjustment unit 700 is illustrated. A side view diagram 710A shows telescopic length adjustment unit 700 in a lock state after a particular length has been achieved. Telescopic length adjustment unit 700 includes size adjustment knob 107 connected to an axle 701 wrapped around by a spring 702. Axle 701 is connected to a rotatable lock member 704 which is rotated on an inner telescopic member 705. In the lock position, rotatable lock member 704 is locked or stopped by an array of first stoppers 711. In addition, inner telescopic member 705 is firmly locked by array of slider locks 712 and array of stationary locks 714. Array of slider locks 712 are permanently fused to inner telescopic member 705 while array of stationary locks 714 are permanently fused to outer telescopic member 703. In the lock position, array of slider locks 712 and array of stationary locks 714 are mated as shown in a top view diagram 720A. Furthermore, in the lock position, spring 702 lifts inner telescopic member 705 up and out of slide tracks 715 situated on bottom sides of outer telescopic member 703. Because of this, outer telescopic member 703 cannot slide out to extend the length of size adjustment keys 222.
(28) Next referring to FIG. 7B, a side view diagram 710B and a top view diagram 720B show telescopic length adjustment unit 700 in an unlocked state designed to reach a particular length such as 10 mm or 3 mm. First, axle 701 (connected to rectangular lock key 704) is pressed down from size adjustment knob 107 until inner telescopic member 705 touch slide tracks 715. At that moment, arrays of locks 714-715 are separated. Then size adjustment knob 107 is rotated in a clockwise direction until the longest length of rectangular key lock 704 is parallel to that of outer telescopic member 703. In this unlock position, inner telescopic member 705 is slid to any desired length. If the length of size adjusting key 222 is 65 cm, then the distance d is 10 mm. When the length of adjusting key 222 is 53 cm, the distance d is 3 mm. In summary, the diameters of output materials can be changed by simple operations of telescopic length adjustment unit 700.
(29) It is noted that other length changing mechanisms such as linear position ratchets, locking button telescoping tubes, rotator locks, etc. are within the scope of the present invention.
(30) Finally, referring to FIG. 8, a flowchart of a method 800 for grinding input materials in a normal mode and a safe mode in accordance with an exemplary embodiment of the present invention is illustrated. In the normal mode, when the size and the hardness of the input materials can be grinded, the breaking of the input materials is handled by the compressive force of the compression chamber. In the safe mode, when the size and the hardness of the input materials cannot be grinded, method 800, by means of a simple mechanical structure, transfers the reactive forces of the input materials to move the components of the grinder to the right and store it in a compression spring to avoid stress and structural damage to the grinder.
(31) Now at step 801, input materials are grinded and smoothened out all the sharp edges. Step 801 is realized by dual slope compression chamber 101 including first section 201 affixed to corrugated plate 208, both forming an angle @ with fixed vertical crushing jaw 204. Movable crushing jaw 203 also includes second section 202 affixed with granular plate 209, both are parallel to and separated to vertical fixed jaw 204 by a distance d. Step 801 is further realized by toggle bar 211, first adjustment structure 221 with slanted surface 223, second adjustment structure 231 sliding up and down slanted surface 223 during normal mode, and safety spring 241. These components are described in FIG. 2A-FIG. 2C, FIG. 3, FIG. 4A-FIG. 4B, and FIG. 5.
(32) At step 802, whether input materials can be grinded is determined. If the input materials can be grinded, then move to step 803. In various preferred embodiments of the present invention, step 802 is realized by the shape of safety spring 241. If safety spring 241 is not compressed but continues to oscillate up and down, then the input materials can be grinded. In some embodiments of the present invention, a simple electrical detector detecting the shape of safety spring 241 signals whether the input materials can be grinded or not.
(33) At step 803, grind and smooth out input materials in a normal mode. Step 803 is realized by dual slope compression chamber 101 including first section 201 affixed to corrugated plate 208, both forming an angle @ with fixed vertical crushing jaw 204. Movable crushing jaw 203 also includes second section 202 affixed with granular plate 209, both are parallel to and separated to vertical fixed jaw 204 by a distance d. Step 601 is further realized by toggle bar 211, drawback spring 202, first adjustment structure 221 with slanted surface 223, second adjustment structure 231 sliding up and down slanted surface 223 during normal mode, and safety spring 241. These components are described in FIG. 2A-FIG. 2C, FIG. 3, FIG. 4A-FIG. 4B, and FIG. 5
(34) Next, at step 804, whether the grinding is finished is determined. In various aspects of the present invention, step 804 is realized by another electrical detector designed to detect if input materials stop inputting.
(35) If the grinding has not finished, then go to step 805, determining whether the size of the output materials is changed. If the sizes of the output materials are change then go to step 806.
(36) At step 806, the distance d between the crushing jaws is changed. Step 806 is realized by size adjusting key 222. More particularly, as described above, the distance between granular surface 209 and fixed vertical crushing jaw 204 is d. Distance d can be changed to adapt to various output sizes of the input materials. A size adjusting key 222 is used to vary the distance d. In some aspects of the present invention, size adjusting key 222 is changed by replacing with another size adjusting key having a different length using the assembly instruction shown in FIG. 5. If the length of size adjusting key 222 is 65 cm, then the distance d is 10 mm. When the length of adjusting key 222 is 53 cm, the distance d is 3 mm. In some other aspects of the present invention, the length of size adjusting key 222 is changed by simply activating size adjustment knobs 107 and telescopic length adjustment unit 700 as described in FIG. 6 and FIG. 7A-FIG. 7B. In other aspects of the present invention, the distance d to change the size of the output materials is changed by disassembled glass grinder 100 as described in FIG. 5.
(37) After the distance d has been changed, then follow a path 807 to resume the normal operation as described in step 801 above.
(38) In case the size of the output materials is not needed to change, still continue on path 807 in normal operation mode in step 801.
(39) If the grinding is finished, at step 808, then turn off power of the motor. Step 808 is realized by power button 103 that are electrically connected to motor 273.
(40) It is noted that method 800 is not necessary performed in the above-described order. In various aspects of the present invention, steps 801-808 of method 600 can be performed in different orders so that the objectives of the present invention are achieved.
(41) The scope of the present invention, however, is not limited solely to these specific examples. Various modifications, whether explicitly stated in the specification or not, such as differences in thickness, oxygen pressure in deposition, stoichiometry, and material usage, are conceivable. The scope of the invention encompasses at least as broad as described by the following claims.
(42) Within the scope of the present description, the reference to an embodiment or the embodiment or some embodiments means that a particular feature, structure or element described with reference to an embodiment is comprised in at least one embodiment of the described object. The sentences in an embodiment or in the embodiment or in some embodiments in the description do not therefore necessarily refer to the same embodiment or embodiments.
