Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, and more specifically, to a plastic recycling crushing device. Background Technology

[0002] Plastic recycling crushing equipment is a specialized device used to crush waste plastics. It is indispensable in the plastic recycling and reuse industry chain. Daily life and industrial production generate a large amount of waste plastics, such as mineral water bottles, plastic films, and plastic buckets. These plastics need to be crushed into small pieces or granules by crushing equipment before they can enter the subsequent cleaning, melting and other stages, and finally be made into new plastic products to achieve resource recycling.

[0003] In existing technologies, plastic crushing results in easily flying debris, posing a safety hazard. The collection and transfer of crushed materials are inconvenient, affecting the efficiency of continuous operation. The protective box is not securely installed, and its opening and closing operations are cumbersome, making equipment maintenance difficult. Furthermore, the connection between the crushing device and the material transfer process is not smooth, reducing the overall processing efficiency. Utility Model Content

Pull the moving rod 24 downward. The moving rod 24 drives the moving plate 9 to move in the moving groove 23 and compresses the moving spring 25, causing the insertion rod 10 to leave the insertion hole 11. Then the protective box 4 can be flipped outward to maintain and repair the crushing box 3. After maintenance is completed, the protective box 4 can be flipped outward. 4. Flip over. After flipping, the connecting rod 6 on the connecting plate 5 extends into the connecting groove 8. Pull down the moving rod 24 and the moving plate 9, and compress the moving spring 25, so that the insertion rod 10 and the insertion hole 11 are aligned. Then release the moving rod 24, so that the moving plate 9, under the elastic force of the moving spring 25, drives the insertion rod 10 into the insertion hole 11, fixing the position of the insertion rod 10. Then rotate the limiting rod 27, so that the sliding block 31 is aligned with the sliding groove 32. Release the limiting rod 27, so that the limiting plate 29, under the elastic force of the limiting spring 30, drives the limiting rod 27 into the limiting hole 28, further fixing the position of the limiting rod 27 and improving the stability of the installation position of the protective box 4.
