[0009] As a further feature of the above solution, the buffer spring is located outside the crushing chamber and is fixedly connected to the crushing chamber.

[0010] This utility model has the following beneficial effects: Plastic is added to the crushing box through the feeding hopper. After being crushed by the crushing roller, the plastic falls onto the screen plate. The electric telescopic rod device drives the screen plate to move back and forth, screening the plastic fragments. The plastic fragments fall directly into the transfer trolley, improving the material transfer efficiency. This device has a simple and reliable structure, which can effectively avoid screen plate blockage and greatly improve the working efficiency of the equipment.

[0011] When it is necessary to clean the screened impurities, use a tool to connect the installation window and the baffle through the connection hole, pull the baffle out of the crushing box, and the electric telescopic rod device continues to drive the screen plate to move back and forth. The travel speed of the screen plate when it is away from the electric telescopic rod device is lower than the travel speed of the screen plate when it is close to the electric telescopic rod device, so that the impurities are automatically discharged from the chip discharge trough, further improving the working efficiency of the equipment.
