Description

Technical Field

[0001] The utility model relates to the field of plastic products, in particular to a waste plastic crushing device for plastic pipe production. Background Technique

[0002] Plastic pipes are produced by plastic extrusion. At present, in the process of recycling plastic products, a plastic crusher is needed to crush and discharge them, which is convenient for subsequent processing and use of plastics. The crushing mechanism of traditional plastic crushers includes two oppositely rotating crushing rollers. Plastics are put into the mutually meshing part of the two crushing rollers and crushed. The crushed plastics fall downward between the two crushing rollers. After retrieving the public number CN219210087U of the patent office database for a plastic raw material crushing device, by rotating the threaded rod to drive the sleeve to displace on the surface of the threaded rod, and then driving the slider to displace in the chute, the distance between the second crushing roller and the first crushing roller is adjusted, and the size of the crushed plastic raw materials is controlled, so as to meet different production requirements, and thus the applicability of the plastic raw material crushing device is improved. However, when plastics are crushed, on the one hand, plastics are likely to directly fall into the inside of the crushing box from the side end of the second crushing roller, and on the other hand, plastics are likely to splash out of the crushing box during crushing;

[0003] Therefore, it is very necessary to invent a waste plastic crushing device for plastic pipe production. Content of the Utility Model
