[0023] Through the above technical solution, first, the plastic products to be crushed are put into the interior of the crushing cover 2 through the side feeding port of the protective cover 3. At the same time, the motor 8 is started through the control panel 17. The output end of the motor 8 drives the corresponding transmission gear 7 to rotate, and the two transmission gears 7 can rotate towards each other through the meshing relationship. Then, the corresponding two crushing rollers 4 can be driven to rotate through the rotating shaft, so as to crush the plastic products.

The output end of the motor 8 drives the corresponding transmission gear 7 to rotate, and the two transmission gears 7 can rotate towards each other through the meshing relationship. Then, the corresponding two crushing rollers 4 are driven to rotate through the rotating shaft, so as to carry out the crushing work on the plastic products. The protective cover 3 can effectively prevent some plastics from splashing out during the crushing process and causing harm to the operator, improving the safety of use. The plastic products after the initial crushing continue to descend inside the crushing cover 2. While the transmission gear 7 is running, it can drive the external first pulley 9 to rotate. The first pulley 9 then drives the second pulley 11 and the rotating rod 10 to rotate through the transmission belt 12, so that the rotating rod 10 drives the internal first bevel gear 13 to rotate. The first bevel gear 13 then drives the second bevel gear 15 and the reciprocating lead screw 14 to rotate through the meshing relationship, so that the reciprocating lead screw 14 drives the slider 5 and the grinding plate 6 to perform a reciprocating up-and-down movement under the limitation of the inner wall of the crushing cover 2, thereby performing secondary grinding on the plastic products after the initial crushing and improving the crushing effect. Finally, the plastic products crushed through the two steps can be discharged through the discharge port 16, which is convenient for the staff to collect centrally. The protective cover 3 in this device can effectively prevent some plastics from splashing out during the crushing process and causing harm to the operator, improving the safety of use. And after the plastic products are crushed by the two crushing rollers 4, they can fall to the grinding plate 6 for secondary grinding, improving the crushing effect and providing convenience for subsequent reprocessing.
