DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(9) Please refer to
(10) The machine seat 2 is disposed at a middle portion of the machine frame 1. The top of the machine seat 2 is provided with a plurality of juxtaposed grooves 21 and a first heating assembly 22. The first heating assembly 22 is embedded in the machine seat 2 and located under the grooves 21. The grooves 21 are used for placing bamboo strips. The first heating assembly 22 is used to heat the bamboo strips placed in the grooves 21. The bottom of the machine cover 3 is provided with a plurality of ribs 31 and a second heating assembly 32. The ribs 31 correspond in position and in number to the grooves 21. The second heating assembly 32 is embedded in the machine cover 3 and located above the ribs 31. When the machine cover 3 covers the machine seat 2, the ribs 31 are just inserted into the grooves 21 to press against the bamboo strips in the grooves 21. The second heating assembly 32 is used to heat the bamboo strips placed in the grooves 21.
(11) The machine cover rail 4 and the push rail 6 are arranged on the machine frame 1, respectively. The machine cover 3 is slidably fitted on the machine cover rail 4. The left side of the machine cover 3 is a curved surface 33, so that the bamboo strips pushed by the push plate 5 are bent along the curved surface 33. The machine cover 3 is connected with the right end portion of the machine frame 1 through the elastic member 8. The push plate 5 is slidably fitted on the push rail 6. The power source 7 is connected with the push plate 5. The machine cover rail 4 includes a left rail section 41 and a right rail section 42 arranged from left to right. The left rail section 41 is arranged along the machine seat 2 and located above the machine seat 2. When the machine cover 3 is not applied with an external force, the machine cover 3 is located on the left rail section 41 and covers the machine seat 2, and the ribs 31 are just inserted into the corresponding grooves 21. When the machine cover 3 is slid to the right rail section 42 by applying an external force, the elastic member 8 is defamed by compression. After the external force is removed, the machine cover 3 slides back to its original position, i.e., the left rail section 41, due to the elastic restoring force of the elastic member 8.
(12) The right end portion of the push plate 5 is bent upwards to form a bent portion 51. The included angle between the bent portion 51 and the push plate 5 is a, and =100-150. The push rail 6 includes a lower linear section 61, a curved section 62 and an upper linear section 63 arranged from left to right. The lower linear section 61 is lower than the grooves 21, so that the push plate 5 can be located a position lower than the bamboo strips placed in the grooves 21 when the push plate 5 slides on the lower linear section 61, so as to ensure that the bent portion 51 can push up the ends of the bamboo strips and bend the bamboo strips upwards when contacting the bamboo strips. The curved section 62 is connected between the upper linear section 61 and the lower linear section 63. The upper linear section 61 is parallel to the left rail section 41 and is located above the left rail section 41. When the push plate 5 is slid to the upper linear section 61, the lower surface of the push plate 5 is attached to the upper surface of the machine cover 3, so that the push plate 5 can push the bamboo strips to move on the upper surface of the machine cover 3.
(13) In this embodiment, the push plate 5 is connected to the power source 7 through a pulley (not shown). The first heating assembly 22 is composed of a plurality of first heating strips 221 that are evenly distributed and staggered with the grooves 21. The second heating assembly 32 is composed of a plurality of second heating strips 321 that are evenly distributed and staggered with the ribs 31. The specific structures of the first and second heating strips 22, 32 can ensure uniform heating for the bamboo strips.
(14) Referring to
(15) The machine cover 3 is pushed to slide to the right rail section 42 and the elastic member 8 is compressed; then, bamboo snips (not shown) are placed one by one in the grooves 21 of the machine seat 2 to ensure that the woody parts of the bamboo snips are attached to the grooves 21. The bamboo snips each have a portion of about 5-8 cm exposed outside the grooves 21 of the machine seat 2, and the exposed portions of the bamboo strips are located on the left side of the machine seat 2, i.e., the exposed portions of the bamboo snips are located between the curved sections 62.
(16) After that, the machine cover 3 covers the machine seat 2. The ribs 31 of the machine cover 3 are adapted to press the bamboo snips. The first heating assembly 22 and the second heating assembly 32 are actuated simultaneously. The first heating assembly 22 and the second heating assembly 32 jointly heat the bamboo snips at a heating temperature of 180-450.
(17) After the bamboo snips are heated and reformed for 3-10 minutes, the first heating assembly 22 and the second heating assembly 32 are turned off. The woody parts of the bamboo snips located at the left side of the machine seat 2 are cut off (Specifically, a cutting blade may be used for cutting to achieve the purpose of cutting the woody parts of the bamboo snips. In general, the cutting thickness is about 1/25 of the thickness of each of the bamboo snips, so as to cut off the woody parts of the bamboo strips.) Then, the power source 7 is turned on to drive the push plate 5 to slide along the push rail 6 and move from the lower linear section 61 to the upper linear section 63. During the sliding of the push plate 5, the bent portion 51 first contacts the bamboo strips to bend and crush the bamboo strips, meanwhile, the cutting edges of the woody parts of the bamboo strips are bent upwardly and reversely under the action of bending and crushing. As the push plate 5 continues to slide, the bamboo strips are pushed to the upper surface of the machine cover 3 by the push plate 5. As the push plate 5 further continues to slide, the bamboo strips are pushed and moved in the direction of the distal end of the machine cover 3, so that the fiber and the base structure are slowly delaminated and peeled and separated out into large bundles from the bamboo strips because of bending, crushing and stretching, so that the bamboo strips are delaminated and split into fiber. Due to stress concentration, the cutting edges of the woody parts of the bamboo strips enables the woody parts of the bamboo strips to be naturally separated into bamboo sheets (that is, the woody part of the bamboo is in the form of a sheet). The woody parts of the bamboo strips can be used as fuel, etc., that is, the woody parts of the bamboo strips are completed separated from the green parts of the bamboo strips.
(18) When the push plate 5 is slid to completely locate on the upper linear section 63, a set of bamboo strips are delaminated into fiber, and then the push plate 5 is returned to the original position, i.e., the upper linear section 61, under the action of the power source 7. Finally, the sepal aced bamboo fiber is taken out.
(19) From the foregoing, it can be seen that the present invention provides a manufacturing method for obtaining bamboo fiber by mechanical and physical properties. Fully utilizing its anisotropic and non-uniform characteristics, bamboo is first heated to change its nature and compelled to move along the curved surface 33 of the machine cover 3. With the sliding of the push plate 5 on the push rail 6, the bamboo is stretched, bent and crushed to be greatly destroyed by geometric nonlinear distortion. Cracks appear in the fiber and base structure of the bamboo during the process. As the cracks continue to expand, the fiber and base structure are separated out into large bundles from the bamboo, so that the woody part of the bamboo is completed delaminated and separated from the green parts of the bamboo, that is, the bamboo is delaminated into fiber (bundle). The entire production process is simple and easy, greatly improving production efficiency and reducing production costs. In addition to realizing the delamination and separation of the woody part and the green part of the bamboo, it not only has a high output rate of fiber, and it is environmentally friendly in production without pollution. The bamboo structure can be deformed by the crush force and bending, so that the obtained bamboo fiber (bundle) has good elasticity, good toughness, fine fiber fineness and uniformity. The manufacturing apparatus 100 for delaminating a bamboo into fiber according to the present invention has a simple structure, is easy for operation and use, occupies less area, and can be used widely.
(20) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
