AI Technical Summary

Technical Problem

Existing PET waste grinding and recycling devices have simple structures, insufficient grinding, uneven particle size, and lack of screening mechanisms, resulting in inconsistent powder quality, which increases the difficulty and cost of subsequent processing.

Method used

The grinding mechanism uses an arc-shaped grinding block and a grinding roller, combined with a reciprocating screw to drive the grinding roller to rotate. It is equipped with a screening mechanism that uses a motor-driven cam to vibrate and screen the powder. The collection mechanism is designed for convenient collection of qualified powder.

Benefits of technology

This process achieves thorough grinding and uniform pulverization of PET waste, improving the quality of subsequent recycling and reducing processing difficulty and costs.

Abstract

The application provides a PET waste material grinding recovery device, which comprises a shell, a feeding hopper is fixedly installed on the upper surface of the shell, a grinding mechanism is arranged in the shell, a screening mechanism is arranged on the lower side of the grinding mechanism, and a collecting mechanism is arranged on the lower side of the screening mechanism; the grinding mechanism comprises grinding blocks, two grinding blocks are arranged, the two grinding blocks are respectively installed on the inner wall surfaces of the two sides of the shell, the opposite side surfaces of the grinding blocks are arranged in an arc shape, and the arc surfaces of the grinding blocks are matched with grinding rollers. Through the use of the grinding mechanism, the two arc-shaped grinding blocks are closely matched with the grinding rollers, the grinding contact area is increased, the PET waste material is fully ground, the first motor drives the reciprocating lead screw, the grinding roller can be driven to reciprocate, the problems of insufficient grinding and uneven particles of the traditional device are effectively solved, and the quality of subsequent recycling and utilization is ensured.
