Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe processing equipment, in particular to a crushing pretreatment device for PE pipe processing. Background Art

[0002] Due to its high strength, corrosion resistance, non-toxicity and other characteristics, PE (polyethylene) materials are widely used in the field of water supply pipe manufacturing. Because it does not rust, it is an ideal pipe material to replace ordinary iron water supply pipes. The PE pipe buried underground does not need to reach the same strength and rigidity as the "rigid pipe" to meet the mechanical property requirements in underground use.

[0003] At present, since PE pipes are thermoplastic plastics, during the recycling process, the PE pipes need to be crushed first, and then the pipe fragments are cleaned. After cleaning, screening, color sorting, and smelting processing are carried out. However, since the PE pipes are long pipes, it is difficult to enter the crusher during crushing, which causes great inconvenience to crushing. It is necessary to perform pre-cutting treatment to reduce the size of the PE pipes before crushing. The existing crushing pretreatment equipment cannot completely reach the cutting position, and for PE pipes with different pipe diameters, the cutting equipment cannot complete the cutting work on all sides of the PE pipes at one time, and there is a problem that the size of the cut pipes is limited.
