[0086] These are terms of art commonly used in CNC machining technology.
[0087] As shown in
[0088] The control system adjusts the pressing assembly 5 so that the pressing roller 51 applies a squeezing force to the stone material. The coloring component 4 applies color material to at least one surface of the layer to which the pressing force has been applied. Layer color material or according to the design path of the final product texture, applies at least one layer of color material at the corresponding position on the surface of the slab material.
[0089] The control system adjusts the moving assembly 1 and the stirring assembly 2 so that the moving assembly 1 drives the stirring assembly 2 above the slab after the squeezing force is applied, and according to the setting of the final product texture. As the stirring assembly 2 moves along its route, the stirring assembly 2 stirs at all programmed positions or partial corresponding positions on the surface of the slab, so that stirring occurs between the color material layer applied on top and the raw material mixture layer underneath.
[0090] The pressing assembly 5 and the stirring component 2 can be mounted together at the same station, or can be mounted separately as two independent stations connected by a belt. Driven by the belt, the stirring component 2 can be moved to the working area of the pressing assembly 5. The pressing assembly 5 applies a certain squeezing force to the slab or plate, and then, the color component 4 applies at least one layer of color to the surface of the slab or plate. According to cosmetic design, the color component 4 path of the final product texture, applies at least one layer of color material uniformly or unevenly on the corresponding position of the working surface. After application of the coloring material is completed, the moving assembly 1 drives the stirring assembly 2 to move along the extending path of the final product texture. At the same time, the stirring assembly 2 performs the stirring at the corresponding position according to the preprogrammed texture and design to facilitate stirring between the coloring material on an upper material layer and the raw material mixture on a lower material layer. The depth of the stirring may involve the thickness of the entire slab. The position of the agitated position after stirring and the position of the unstirred position will produce a color difference. Inside the mixture, after the texture processing and subsequent curing, pressing, thickness setting and other processes are completed, a transparent texture effect is left on the surface of the slab.
[0091] Before mixing, a certain squeezing force is applied to the slab material through the pressing assembly 5, so that the mixing occurs between the raw material mixture and the color material of the more compact plate material, and the material at the mixing position becomes loose again, and the material in the adjacent unstirred position is compacted due to the previous pressing, and there is a large barrier that allows the colorant to penetrate, so that the colorant is well maintained at the position where it is stirred, macroscopically making the final product textured. The boundary is clearer and more complete, and the consistency of the upper and lower textures and the texture permeability are good. The texture effects of the surface and the bottom layer are very clear, which truly achieves the natural crack effect.
[0092] For the specific implementation of the pressing assembly and the stirring component, there are the following two general embodiments.
Example 1
[0093] As shown in
[0094] The pressing assembly 5 and the stirring component 2 are set on two independent stations that are relatively spaced apart from each other. The slab can be handled so that it is movable such supported on a slab conveyor belt so that the slab passes the working area of the two components pass over the working area to complete their respective functions. Alternatively, the two components can be mounted at a single station or separately. The mounting locations reduce the time that the slab stays in one station, and reduces the waiting time for the next slab to start processing, thereby compacting the product process time and improving production efficiency. In addition, in a relatively independent station, one may operate variations of the process, although a flexible combination arrangement is required, where multiple pressing assemblies 5 and/or stirring components 2 can also be added in the middle according to process requirements, so as to achieve a richer texture effect.
[0095] In this embodiment, one of the corresponding setting methods of the color application component (that is, the first implementation of the application coloring component) is performed by a common dusting method, as shown in
[0096] The application color material assembly 4 is fixed on the frame 3, and the slab is continuously driven by the conveyor belt. When the slab material moves to the application color material assembly 4, the control system drives the discharge roller 42 and the fabric to rotate. The color material in the hopper 41 is carried out by the discharge roller 42 to provide a natural fall to the surface of the slab material to apply the color material. The natural falling of powdered material provides a sprinkling effect.
[0097] The color application member 4 can apply at least one layer of color on the entire surface of the slab. The screen 43 provided below the discharge roller 42 filters the color material in the final step to ensure that there are no large lumps of color material sprayed onto the slab material to ensure the cloth effect.
[0098] Another corresponding arrangement method of applying coloring material components is shown in a second embodiment of applying coloring material components, which adopts a matrix dusting method, as shown in
[0099] The dosing color component 4 is fixed on the frame 3, and the slab is continuously driven by the conveyor belt. When the slab moves to the color component 4 for color application, the control system drives the switch control valve of the color spray head 442 to open. The color material in the storage tank 44 naturally falls to the surface of the slab material through the color material spray head 442 to apply the color material.
[0100] The interval section 441 of the storage barrel 44 of the applied color material assembly 4 can be placed with different colors or different types of colorants. A plurality of colorant spray heads 442 are respectively arranged in the plurality of interval sections of the spray head rows 441 and are arranged along the lateral direction of the belt conveyor. This arrangement can ensure that the color material is covered in the width direction of the slab material, and each fixed nozzle is arranged below the storage barrel 44 to ensure that the material in the storage barrel 44 can be sprayed out.
[0101] As shown in
[0102] The conveyor belt 55 can be linearly reciprocated above the cloth platform, and during its movement, the rolling belt 54 can push and squeeze the powdered stone quartz onto the cloth platform. After enough material is stored on the cloth belt 53, the conveyor belt 55 moves the cloth belt 53 and the rolling belt 54 forward over the cloth platform. The cloth belt 53 is transported forward, and the rubbery material on it falls onto the rolling belt 54, and the roller belt 54 is transported forward, so that the rubbery material obtained on it falls into the mold on the cloth platform.
[0103] A height difference between the roller belt 54 and the cloth platform can be adjusted so that the roller belt 54 pushes and squeezes the powdered stone quartz during the distribution process, so that the powdered stone quartz continuously squeezes toward and against the side wall of the mold. The gap between the powdered stone quartz mass is eliminated and the mortar like material around the mold is extruded. The two previously separate processes of fabric and blank forming in the prior art are now completed in a single step together to improve work efficiency and avoid multiple blank transfer process iterations, thereby improving the quality of slab blank forming.
Example 2
[0104] As shown in
[0105] One of the corresponding setting methods of the application coloring material component of the present embodiment (that is, the third embodiment of the application coloring material component) is carried out by using the XYZ axis moving dusting method, which is provided on the moving component 1, and is moved by the moving assembly 1 together with the agitating assembly 2. The distributing coloring component 4 includes a coloring material spraying head and a coloring material bucket 47, and the coloring material spraying head communicates with the coloring material through a conveying pipe by which the barrel 47 is in communication.
[0106] Another corresponding setting method of the application coloring material component of this embodiment (i.e., the fourth implementation type of the application coloring material component) is also carried out by using the XYZ axis moving dusting method, as shown in
[0107] The storage barrel 47 does not move with the moving sprinkler, which can reduce the weight of the moving frame 45 and its motion inertia, and improve the positioning accuracy when the mobile sprinkler starts and stops, or when it turns.
[0108] In this embodiment, the interlayer mixing device is provided on the frame 3, and the frame 3 is provided with a platform to receive the slab material. As shown in
[0109] The pressure roller 51 is arranged above the conveyor belt parallel to the conveyor belt. During the process of the conveyor belt entering the working area of the stirring assembly 2 with the conveyor belt, the pressing force is applied by the pressure roller under the pressure roller 51. The height of the press roller in the vertical direction can be adjusted to meet the processing of different thicknesses of slabs.
[0110] Furthermore, as shown in
[0111] In this embodiment, the moving assembly 1 is a driving device with degrees of freedom in the three directions of the X axis, the Y axis, and the Z axis. Any conventional structure that can carry the stirring assembly 2 in a linear reciprocating motion in the above three directions should suffice. Within the scope of protection of the present invention, such conventional structures include various forms of structures composed of one or more combinations of conventional equipment such as motors, cylinders, gear racks, slide rail sliders, cams, sprockets, screw rods, etc. A specific embodiment of the moving assembly 1 is, as shown in
[0112] Further, the X-direction drive member and the Y-direction drive member are both structures including a drive reducer 13, a drive gear 14 and a drive rack 15. The drive rack 15 in the X-direction drive member is provided on the frame 3 and extended along the X-axis direction. The drive reducer 13 and the drive gear 14 are mounted on the carriage 11. The drive reducer 13 drives the drive gear 14 to rotate and reciprocates along the drive rack 15 in a straight line. The driving rack 15 is provided on the traveling frame 11 and extends along the Y-axis direction, and the driving reducer 13 and the driving gear 14 are mounted on the spindle mounting plate 12. The driving reducer 13 drives the driving gear 14 to rotate and along the driving rack 15 to make a linear reciprocating motion.
[0113] The Z-direction drive is a Z-direction drive reducer 16, a screw assembly 17 and a Z-direction mounting plate 18. The stirring assembly 2 is provided on the Z-direction mounting plate 18. The Z-direction mounting plate 18 is fixedly connected to the nut of the screw assembly. The screw of the rod assembly 17 is rotatably provided on the spindle mounting plate 12, and extends along the direction of the Z axis, and rotates under the drive of the Z-direction drive reducer 16. The screw assembly 17 is used to achieve moving position fine adjustment and precise positioning. Further, a fast moving mechanism 19 is provided above the spindle mounting plate 12, and the fast moving mechanism 19 can drive the stirring assembly 2 to move up and down in the vertical direction quickly, that is, when the stirring spindle 222 is not in operation, the stirring assembly 2 is carried for quickly rising and resetting. When working, the stirring assembly 2 can be quickly lowered to a position close to the processing surface, and then the spindle mounting plate 12 can be lowered through the Z-direction driving member, so that the stirring blade 21 falls accurately to the processing position, and the processing efficiency and precision are improved. The fast-moving mechanism 19 here may be one or more of mechanical structures such as cylinders, cylinders, gears, cams, sprockets and so on.
[0114] Preferably, the driving gear 14 and the driving rack 15 here are helical gear racks, and the tooth overlap of the helical gear rack is large, which reduces the force of each tooth, making the driving gear 14 and the driving rack 15 more durable and transmission more stable with low noise. In order to further improve the stability of the movement in all directions, between the walking frame 11 and the frame 3, before the walking frame 11 and the spindle mounting plate 12, the linear guide slider assembly 191 is provided at the position where the two are in contact with each other. The linear guide rail has low frictional resistance to movement, wear and tear for a long time, and good accuracy.
[0115] The agitating component 2 applies at least one layer of color material on the surface, or works on the plate material applying at least one layer of color material at a corresponding position on the surface of the plate material according to the design path of the final product texture. The slab is placed horizontally, and the driving device 22 drives the stirring blade 21 to rotate in a vertical plane. When passing through the slab, the raw material mixture of the color material and the slab are stirred with a tangential force. The depth of the stirring may involve the entire slab thickness. There is a color difference between the agitated position and the non-agitated position after agitation, which after agitation causes the color material to penetrate into the raw material mixture of the slab. After the texture processing and subsequent curing, pressing, and thickness setting are completed, the plate surface of the material leaves a transparent texture effect.
[0116] The material mixture of the color material and the slab material is stirred with a tangential force. Compared with the stirring of the color material and the material mixture by the rotation force perpendicular to the plate material, this technical solution can obtain a finer stirring path. The stirring path obtained by tangential force stirring is the thickness of the tool itself, and if the rotation force obtained by using the rotation force perpendicular to the slab is twice the width of the tool, no matter how the width of the tool is adjusted. There is a process of obtaining a fine texture. Above, the solution of the present invention has outstanding advantages, and from the perspective of actual use, it is impossible for the stirring blade 21 to be made too thin in order to obtain a fine texture. Here, too thin means that the strength of the blade itself is reduced, and stirring has a certain adhesion. When the raw material mixture is mixed, problems such as breakage are extremely easy to occur.
[0117] As shown in
[0118] The stirring blade 21 follows the spindle reducer 223 and rotates relative to the stirring spindle 222. The stirring blade 21 is driven by a spindle drive motor 221, a stirring spindle 222 and a spindle reducer 223. The stirring blade 21 could be mounted on a chuck for easy replacement. The output shaft of the spindle reducer 223 is arranged horizontally and horizontally, driving the stirring blade 21 to rotate horizontally, and the horizontal rotating stirring blade 21 to the plate. During the texture mixing process, the horizontal rotating stirring blade 21 can lift the agitated material upward, and then lift it back to the position of the mixing texture. At the same time, it also acts as a filler to ensure that the agitated texture position will not cause the density of the board to be reduced or small hole defects due to lack of material. The moving trajectory of the stirring blade 21 is determined according to the set texture path. When moving to the corner of the path, the C-axis motor 225 drives the hollow rotary table 224 to rotate through an angle. The angle of rotation is determined by the turning angle of the preset path. The rotation of the rotary table 224 drives the stirring blade 21 to follow rotation, ensuring that the cutting direction of the stirring blade 21 can preferably be always kept in the tangent direction with the moving track when turning, so that the path angle of the path cut by the stirring transition is smooth, if such a smooth design is desired.
[0119] As shown in
[0120] The blade body 212 is flat and in the shape of a plane. The end surfaces of all the blade bodies 212 are in the same plane. A fine texture range can be cut when stirring and cutting the slab. In addition, the blade body 212 can also be made into an end bend (that is the free end of the blade body 212 is provided with a bent portion 2110), so that a larger texture range can be stirred.
[0121] As shown in
[0122] As shown in
[0123] The return scraper 23 is an angular structure composed of a scraper blade 231 and a fixed plate 232. The fixed plate 232 is disposed on the spindle speed reducer 223 so that the scraper blade 231 is located on the stirring blade 21 rear side. The structure is simple, easy to install and use.
[0124] The height position of the return scraper 23 on the spindle speed reducer 223 is adjustable. The method for adjusting the height in this embodiment may be to provide a plurality of buckling positions in the height direction, and the return scraper 23 may be fixed to different buckling positions to achieve height adjustment, or may be through a rack and pinion. The adjustment methods involved in automatic accessories such as motors or cylinders, such as slider rails, that is, height adjustment structures commonly used by those skilled in the art should fall within the protection scope of the present invention.
[0125] Assembly of the machine begins with mounting the moving assembly 1 is movably mounted over the frame 3, and supporting a stirring assembly 2 that is mounted to the moving assembly 1. The moving assembly also has a carriage 11, a spindle mounting plate 12, a drive reducer 13, a drive gear 14, a drive rack 15, a Z-direction drive reducer 16, a screw assembly 17, a Z-direction mounting plate 18, a rapid movement mechanism 19, and a linear guide slider assembly 191. Then, the mixing assembly 2, is mounted to the moving assembly 1. The mixing assembly 2 has a stirring blade 21, blade bar 211, blade body 212, mixing spindle 22, spindle drive 23, scraper blade 231, spindle reducer 232, hollow rotary table 233, C-axis motor 234, and return scraper 24. Then, the coloring component 4 is mounted over the frame 3 and configured so that it distributes color. The coloring component 4 has a cloth hopper 41, a discharge roller 42, a screen 43, a storage barrel 44, interval spaced sections of spray head rows 441, color spray heads 442, a moving frame 45, a walking drive 46, and a color storage barrel 47. Then, the pressing assembly 5 is mounted over the frame 3. The pressing assembly translates across the frame 3 and has a pressing roller 51, a rotating base 52, a cloth belt 53, a rolling belt 54, and a conveyor belt 55. The walking drive 46 can be a step motor.
[0126] The technical principles of the present invention have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention, and should not be interpreted in any way as limiting the protection scope of the present invention. Based on the explanation here, those skilled in the art can associate other specific embodiments of the present invention without creative efforts, and these methods will fall within the protection scope of the present invention.
