[0033] As an embodiment of the present invention, it also includes a particle secondary crushing mechanism, which is used to perform secondary crushing on unqualified powder after multiple crushings. The particle secondary crushing mechanism includes a second gearbox 18 installed on the rear side of the rear vertical plate 2, and the input shaft of the second gearbox 18 is fixedly connected to the second gear 19. A second piston cylinder 27 is installed on the rear side of the rear vertical plate 2. A third piston block 34 that can slide left and right is arranged in the second piston cylinder 27. A limiting ring is installed at the opening of the second piston cylinder 27. A rack 26 is fixedly connected to the right side of the third piston block 34, and an L-shaped guide rod 25 is fixedly connected to the rear side of the vertical plate 2 on the rear forehead.

[0034] As an embodiment of the present invention, the horizontal portion of the L-shaped guide rod 25 passes through the rack 26 and is slidably connected. The rack 26 cooperates with the second gear 19. Here, in the initial state, the rack 26 is not engaged with the second gear 19, and it needs to move a little distance to the right to engage with the second gear 19. The left space of the second piston cylinder 27 is connected to the left space of the columnar cavity 29 through a connecting pipe 24. A normally open solenoid valve is installed in the connecting pipe 24. The normally open solenoid valve is opened and closed synchronously with the drive motor 6. A fine hole 41 is opened on the rear side wall of the left space of the second piston cylinder 27. The left side of the third piston block 34 is connected to the second piston cylinder 27 through a third spring. 7 is elastically connected to the left inner wall of the adjusting cylinder 10, the first spring 30 and the third spring are both springs with larger stiffness coefficients, and the stiffness coefficient of the third spring is greater than the stiffness coefficient of the first spring 30, a rotating shaft 11 is rotatably connected between the two vertical plates 2, a first gear 16 is mounted on the rotating shaft 11, a gear ring 12 is fixedly connected to the outer side of the adjusting cylinder 10, the gear ring 12 is meshed with the first gear 16, the rear end of the rotating shaft 11 passes through the vertical plate 2 on the rear side, and is fixedly connected to the output shaft of the second gearbox 18, the first gearbox 20 is an acceleration box, the second gearbox 18 is a reduction box, and has a reversing structure inside, which allows the rotation of the input shaft and the output shaft to be opposite.

[0035] In the present invention, in actual use, after the photovoltaic glass and the back plate are inserted into the inner side of the U-shaped plate 14 from the feeding port 5 on the front side, the crushing assembly 13 is started to crush. During the crushing process, the driving motor 6 can be started to rotate slowly counterclockwise, and the slow counterclockwise rotation of the driving motor 6 will rotate the notched rubber column 7, and the rotation of the notched rubber column 7 will intermittently contact the adjusting cylinder 10. By utilizing the larger contact friction between rubbers, when the notched rubber column 7 contacts and rotates relative to the adjusting cylinder 10, it will drive the adjusting cylinder 10 to rotate clockwise. If the notched rubber column 7 does not rotate, the adjusting cylinder 10 will rotate clockwise. When contacting the adjusting cylinder 10, since the center of gravity of the whole formed by the adjusting cylinder 10, the first curved plate 37 and the second curved plate 36 is at a lower position, this method can ensure that in the absence of external force, the adjusting cylinder 10 will automatically rotate until the first curved plate 37 and the second curved plate 36 are directly below, that is, at this time the adjusting cylinder 10 will automatically rotate, and finally stop moving when the second curved plate 36 contacts the abutting plate 43. During this process, the adjusting cylinder 10 will continue to shake in both directions, which has a certain screening effect, and small particles of crushed material will be discharged from multiple screening holes 38.

[0036] Each time the adjusting cylinder 10 rotates, it will eventually contact the second curved plate 36. Due to inertia, the contact speed is relatively high. The reaction force generated by the contact impact will cause the adjusting cylinder 10, the first curved plate 37 and the second curved plate 36 to vibrate. This vibration can further improve the screening effect and promote the separation of small particle crushed materials from unqualified large particle crushed materials.

[0037] It should be noted that when the adjustment cylinder 10 rotates forward and reversely, the arc-shaped protrusion 44 will intermittently contact the movable column 15. In this way, under the elastic action of the second spring 39, the first arc plate 37 and the second arc plate 36 will vibrate back and forth. In this way, the separation effect can be further promoted.

[0038] In addition, the two plate-shaped electromagnets 4 can also be started. During the falling process of the small-particle crushed material, the magnetic impurities therein can be sucked into the two plate-shaped electromagnets 4 to realize the operation of removing the magnetic metal. Moreover, due to the cooperation of the vibration, shaking and shaking in the above process, the falling small-particle crushed material is relatively dispersed, so that the magnetization effect is better and the removal of the magnetic metal is more uniform.

[0039] The start of the drive motor 6 will also allow the rotating disk 21 to rotate rapidly through the first gearbox 20. The rapid rotation of the rotating disk 21 will allow the second piston block 33 to reciprocate up and down through the drive rod 22. In conjunction with the use of the first one-way tube 28, the second one-way tube 32 and the internal one-way valve, a one-way gas flow between the outside, the first piston cylinder 23 and the left side space of the columnar cavity 29 can be generated. In this way, the gas continues to accumulate, and the first piston block 31 will automatically move to the right and compress the first spring 30. After a period of subsequent crushing, some large particles of crushed materials are accumulated at the inner bottom of the adjusting cylinder 10, and the drive motor 6 is turned off (when the notched rubber column 7 does not contact the adjusting cylinder 10). At this time, the normally open solenoid valve is also de-energized and turned on. Under the elastic action of the first spring 30, the first piston block 31 quickly moves to the left, and a large amount of gas is released into the space on the left side of the second piston cylinder 27. The exhaust speed of the fine hole 41 is slow, so a large amount of gas accumulates, causing the air pressure in the space on the left side of the second piston cylinder 27 to rise rapidly, thereby pushing the third piston block 34 to quickly The gear 16 is rotated counterclockwise rapidly by meshing the rack 26 with the second gear 19, and the transmission of the second gearbox 18 and the rotating shaft 11. The adjusting cylinder 10 is rotated clockwise rapidly by the gear ring 12. During the rapid rotation, the centrifugal force is used to rotate the large particles of crushed materials gathered at the bottom to the top. It should be noted that the third piston block 34 can only move left to the limit ring. The high-pressure gas will eventually be released through the fine hole 41. This time period is 20-25 seconds, and the first When the three piston blocks 34 move right to the limit ring, the transmission of each transmission part is used to adjust the cylinder 10 to rotate just half a circle. The adjusting cylinder 10 will stay there for about 20 seconds and finally rotate with the return of the rack 26. In this way, the large particles of crushed materials gathered at the bottom rotate to the top and then stop rotating. Under the action of gravity, they will fall to the crushing component 13 to achieve secondary crushing. Compared with the existing technology, there is no need to screen the particles separately and re-add them manually, which optimizes the actual steps and improves the overall efficiency.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
