The moving assembly includes a moving rod 109, a moving sleeve 110 and a driving member. The driving member includes a double-headed screw 112 and a second motor 113. The crushing device further includes a guiding assembly. The guiding assembly includes a mounting plate 114 and a guide rod 115. Through the foregoing solution, the problem that due to the different sizes of different plastic products, if a larger plastic product falls into the casing of the foregoing device, it will slip on the crushing roller, so that the crushing roller cannot crush the plastic product is solved. The foregoing solution can be used in the scenario of plastic recycling and crushing, and can also be used to solve the problem of collecting plastics after crushing.
[0022] In this embodiment, through the opposite driving of the two sides of the extrusion block 105 by the moving assembly, the extrusion block 105 can squeeze the larger plastic product to become smaller, so that it can be smoothly crushed by the crushing cylinder 106.
[0023] Among them, the guide rail 104 is fixedly installed in the crushing chamber 101 and is located on one side of the crushing chamber 101 close to the hopper 102. The extrusion block 105 is slidably installed on the guide rail 104. The moving assembly drives the extrusion block 105 to move. The crushing cylinder 106 is rotatably installed in the crushing chamber 101 and is located on one side of the crushing chamber 101 close to the guide rail 104. A first motor 108 is further provided outside the crushing chamber 101. The output shaft of the first motor 108 is fixedly connected to the crushing cylinder 106. The cutter teeth 107 are fixedly installed on the crushing cylinder 106. The number of the guide rails 104 is two groups, and they are symmetrically distributed on the front and rear sides of the crushing chamber 101. The number of the extrusion blocks 105 is also two groups, and they are symmetrically distributed on the left and right sides of the guide rail 104. One side of the extrusion blocks 105 facing each other is an inclined surface. The number of the crushing cylinders 106 and the first motors 108 is both two groups, and they are symmetrically distributed on the left and right sides of the crushing chamber 101. The crushing cylinder 106 is located below the extrusion block 105. The first motor 108 is fixed to the outside of the crushing chamber 101 by screws. A plurality of groups of the cutter teeth 107 are annularly distributed on each group of the crushing cylinders 106. The moving assembly can drive the two extrusion blocks 105 to move towards each other. By driving the crushing cylinder 106 to rotate through the first motor 108, the cutter teeth 107 on the crushing cylinder 106 can crush plastic products. By driving the two extrusion blocks 105 to move towards each other through the moving assembly, the extrusion blocks 105 can squeeze larger plastic products to become smaller, so that they can be smoothly crushed by the crushing cylinder 106.
[0024] Secondly, a moving groove 111 is provided on one side of the crushing chamber 101. The moving rod 109 penetrates through the moving groove 111 and is fixedly connected to the extrusion block 105. The moving sleeve 110 is fixedly installed on the moving rod 109 and is located outside the crushing chamber 101. The driving member drives the moving sleeve 110 to move. The number of the moving rods 109 and the moving sleeves 110 is two groups, and they are symmetrically distributed on both sides of the moving groove 111. The inside of the moving sleeve 110 is provided with threads. The moving rod 109 is welded to the bottom of the moving sleeve 110. By driving the two moving sleeves 110 to move towards each other through the driving member, the moving sleeve 110 drives the moving rod 109 to move towards each other, so that the moving rod 109 further drives the extrusion block 105 to move synchronously, thereby realizing the moving effect of the extrusion block 105.
[0025] Again, the second motor 113 is fixedly installed outside the crushing bin 101; the double-headed screw 112 is fixedly installed on the output shaft of the second motor 113 and threadedly penetrates through the moving sleeve 110. The second motor 113 is fixed to the outside of the crushing bin 101 by screws, and the double-headed screw 112 is welded to the output shaft of the second motor 113. The thread directions at both ends of the double-headed screw 112 are opposite. The second motor 113 drives the double-headed screw 112 to rotate, and the double-headed screw 112 drives the moving sleeve 110 to move towards each other through the threaded cooperation with the moving sleeve 110, thereby achieving the moving effect of the moving sleeve 110.
[0026] Finally, the mounting plate 114 is fixedly installed inside the crushing bin 101; the guide rod 115 is fixedly installed on the mounting plate 114 and penetrates through the pressing block 105. The mounting plate 114 is fixed to the side wall of the crushing bin 101 by screws, and the guide rod 115 is welded to the mounting plate 114. Through the cooperation of the mounting plate 114 and the guide rod 115, the moving stability of the pressing block 105 can be ensured.
[0027] In this embodiment, during use, plastic products are poured into the crushing bin 101 through the hopper 102. At the same time, the first motor 108 is started, so that the two first motors 108 drive the two groups of crushing cylinders 106 to rotate in opposite directions and crush the plastic products. The crushed plastic is collected by the collecting device. When encountering larger plastic products, the second motor 113 is started to drive the double-headed screw 112 to rotate. The double-headed screw 112 drives the moving rods 109 on the moving sleeves 110 to move towards each other through the threaded cooperation with the two groups of moving sleeves 110. The movement of the moving rods 109 drives the two groups of pressing blocks 105 to move towards each other on the guide rails 104. With the cooperation of the two groups of pressing blocks 105, the volume of the larger plastic products becomes smaller, so that they can be smoothly crushed by the crushing cylinders 106.
