The outer walls of the two groups of movable rods 1503 are sleeved with a return spring 1504, and the return spring 1504 is located between the shell 1502 and the movable plate 1505. The ends of the two groups of movable plates 1505 facing away from the movable rod 1503 are connected to the limiting rod 1506, and the outer sides of the two groups of connecting blocks 1401 are provided with a limiting groove 1507 that is plugged into the limiting rod 1506. When it is necessary to release the fixing effect of the movable plate 1505 on the connecting block 1401, the rubber ball 1501 is pulled outward, and the rubber ball 1501 drives the movable plate 1505 to move through the movable rod 1503 and compresses the return spring 1504. When the movable plate 1505 moves, it drives the limiting rod 1506 to move until the limiting rod 1506 is separated from the limiting groove 1507.

[0035] Please refer to the attached figure in the instruction manual Figure 1 A crushing box 3 is installed on the top of the recovery box 6. A crushing roller 4 is symmetrically connected to the inside of the crushing box 3. A discharge port 12 is opened at the bottom of the crushing box 3 and the top of the recovery box 6. A guide plate 5 is installed obliquely on the inner bottom wall of the crushing box 3, and the lower end of the guide plate 5 is fixedly connected to the discharge port 12. In this way, the crushed scraps can be guided into the interior of the recovery box 6 through the guide plate 5.

[0036] Please refer to the attached figure in the instruction manual Figure 2 and Figure 4 A feeding frame 2 is installed on the top of the crushing box 3, and the inside of the feeding frame 2 is symmetrically connected to the traction roller 1. A driving assembly 13 is arranged between the traction roller 1 and the crushing roller 4. The driving assembly 13 includes two groups of large gears 1304, which are respectively installed on the outside of the crushing box 3. The two groups of large gears 1304 are meshed and connected. The inside of the two groups of large gears 1304 are both sleeved with a second rotating shaft 1305. The front ends of the two groups of second rotating shafts 1305 extend into the interior of the crushing box 3 and are fixedly connected to the front ends of the two groups of crushing rollers 4.

[0037] Please refer to the attached figure in the instruction manual Figure 2 and Figure 4, pinions 1301 are symmetrically installed on the upper end of the outer side of the feed frame 2, and the two groups of pinions 1301 are meshed and connected. The inner cavities of the two groups of pinions 1301 are sleeved with the first rotating shaft 1302, and the front ends of the two groups of first rotating shafts 1302 extend into the interior of the feed frame 2 and are fixedly connected to the front ends of the two groups of traction rollers 1, and mounting seats 1307 are installed on the outer sides of the feed frame 2 and the crushing box 3. A drive motor 1306 is installed inside the mounting seat 1307, and the power output end of the drive motor 1306 is connected to one of the groups of second rotating shafts 1305, and a transmission member 1303 is arranged between one group of first rotating shafts 1302 and the second rotating shaft 1305. When the driving motor 1306 is working, it drives the second rotating shaft 1305 to rotate, and the rotation of the second rotating shaft 1305 drives the large gear 1304 to rotate. Since the two sets of large gears 1304 are meshed and connected, the two sets of second rotating shafts 1305 can drive the two sets of crushing rollers 4 to rotate. While the second rotating shaft 1305 rotates, it drives the first rotating shaft 1302 to rotate through the transmission member 1303. The rotation of the first rotating shaft 1302 drives the small gear 1301 to rotate. Since the two sets of small gears 1301 are meshed and connected, the two sets of traction rollers 1 can be driven to rotate through the two sets of first rotating shafts 1302.

[0038] Please refer to the attached figure in the instruction manual Figure 2 and Figure 4 The transmission member 1303 includes a first pulley 13031, which is fixedly mounted on the outside of one of the first rotating shafts 1302. A second pulley 13033 is fixedly mounted on the outside of one of the second rotating shafts 1305. A connecting belt 13032 is provided for the external transmission of the first and second pulleys 13031 and 13033. When the second rotating shafts 1305 rotate, the second pulleys 13033 rotate. The rotation of the second pulleys 13033 drives the first pulley 13031 through the connecting belt 13032, which in turn drives the first rotating shafts 1302.

[0039] Working principle: When in use, turn on the drive motor 1306. When the drive motor 1306 is working, it drives the second rotating shaft 1305 to rotate. The second rotating shaft 1305 drives the first rotating shaft 1302 to rotate through the transmission member 1303. The rotation of the first rotating shaft 1302 drives the pinion 1301 to rotate. The two sets of pinion gears 1301 are meshed and connected, and then the two sets of first rotating shafts 1302 can drive the two sets of traction rollers 1 to rotate. The transmission guide of the two sets of traction rollers 1 allows the film edge material to enter the interior of the crushing box 3.

[0040] At the same time, the second rotating shaft 1305 rotates to drive the large gear 1304 to rotate. Since the two sets of large gears 1304 are meshed and connected, the two sets of crushing rollers 4 can be driven to rotate through the two sets of second rotating shafts 1305, thereby crushing the edge materials.

[0041] The crushed scraps enter the recycling box 6 through the discharge port 12 under the guidance of the guide plate 5. When the scraps in the recycling box 6 reach a certain amount, the electric push rod 8 extends to drive the push plate 9 to move to the right, squeezing the scraps in the recycling box 6, reducing the volume of the scraps inside the recycling box 6 and increasing the amount of scraps that can be recycled by the equipment.

[0042] When the scraps need to be taken out, the rubber ball 1501 is pulled outward, and the rubber ball 1501 drives the movable plate 1505 to move through the movable rod 1503 and compresses the return spring 1504. The movable plate 1505 moves and drives the limiting rod 1506 to move until the limiting rod 1506 is separated from the limiting groove 1507, thereby releasing the fixing effect of the limiting rod 1506 on the connecting block 1401. Then, the handle 10 is pulled to the right to separate the connecting block 1401 from the connecting groove 1402, and the baffle 11 can be removed from the recycling box 6, thereby facilitating the removal of the scraps inside the recycling box 6.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
