AI Technical Summary

Technical Problem

During the plastic recycling process, semi-hard plastic plates such as PP, PE, PA, PVC, etc. are prone to high adhesion and difficult to fully crush during the crushing process, resulting in clogging of the equipment, especially at the inlet.

Method used

A waste plastic plate crushing device is designed, including feed assembly, conveying cylinder and crushing mechanism. A crushing spiral shaft is provided in the crushing mechanism, and its spiral edge is equipped with zigzag cutting sheets for evenly cutting the plastic plates and the cut particles are propelled through spiral advancement to prevent clogging.

Benefits of technology

It effectively prevents clogging at the feed port, ensures that the plastic plate can be cut and broken evenly, and improves crushing efficiency and equipment reliability.
