Description

Technical Field

[0001] The utility model relates to the technical field of pipe crushing, in particular to a plastic pipe crusher. Background Art

[0002] As an important component of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes. Plastic crushers are mainly used to crush various plastics and rubbers, such as plastic profiles, pipes, rods, wires, films, and waste rubber products. The pellets obtained by the crusher can be directly used for extruders or injection molding, or can be recycled through basic granulation. However, the plastic waste crushing devices currently used have the disadvantage of low crushing efficiency.

[0003] The existing public technology disclosed in publication number CN209971217U discloses a waste crushing equipment for plastic pipe production, which solves the shortcoming of low crushing efficiency of the crushing device in the prior art. The equipment comprises a box body and a charging barrel. A feeding port is provided on the top of the box body, and a rolling gear is provided below the feeding port. A first filter layer and a second filter layer are obliquely bonded to the inside of the box body, and the first filter layer is located below the rolling gear. A multi-layer rotary cutting knife is provided on the side of the box body away from the rolling gear. The multi-layer rotary cutting knife is close to the bottom end of the first filter layer, and the second filter layer is located below the multi-layer rotary cutting knife. A knife roll cutting device is provided below the second filter layer, and a third filter layer is obliquely bonded below the knife roll cutting device. A secondary processing discharge port is provided on the side wall of the box body. The utility model has a compact design structure, effectively crushes waste used in plastic pipe production, and improves processing efficiency.

[0004] Although the above patent can perform multi-stage crushing on pipes and improve the crushing quality of pipes, there are still some shortcomings in its use. First, the patent directly puts the pipes into the box through the feeding port for crushing. The crushed pipes are easy to splash out through the feeding port, which not only causes material waste but also pollutes the environment. Secondly, the patent lacks a structure for cleaning the rolling gear. During the pipe crushing process, the pipe fragments are very likely to adhere to the surface of the rolling gear, affecting the crushing effect of the rolling gear. For the problems in the relevant technology, no effective solution has been proposed yet. Utility Model Content
