AI Technical Summary

Technical Problem

Existing foam crushing devices have low efficiency, uneven crushing, high energy consumption and are prone to clogging, making it difficult to efficiently process plastic foam recyclables.

Method used

It adopts a two-stage crushing design, combining pre-crushing and secondary crushing. Through worm and worm gear transmission, a single power source drives multiple mechanisms. It uses negative pressure air ducts to assist in suction and combines buffers to prevent the backflow of crushed materials, ensuring smooth transportation of materials to the secondary crushing components.

Benefits of technology

It significantly improves the crushing efficiency, obtains powder with uniform particle size, avoids the problem of residual large pieces caused by traditional single-stage crushing, reduces energy consumption and improves the stability of system operation and space utilization.

Abstract

The present invention belongs to the field of plastic foam processing and crushing technology, and in particular to a foam processing and crushing device. In view of the fact that the existing foam crushing devices proposed in the background technology mostly adopt a single-stage crushing structure, which has the problems of low efficiency, uneven crushing particles, high energy consumption, etc., the following scheme is proposed, including a machine body, wherein the internal ends of the machine body are respectively provided with a pushing chamber and a foam plate crushing chamber, and the interior of the machine body is provided with a foam pre-crushing mechanism, and a connecting rod is provided on the outer wall of the foam pre-crushing mechanism, and the outer wall of one end of the connecting rod is provided with a foam secondary crushing mechanism. The present invention solves the problems of low efficiency, high energy consumption, and easy clogging of traditional equipment through innovative designs such as double-stage crushing, linked feeding, negative pressure conveying, and gradually shrinking crushing gap. While improving the crushing uniformity and processing efficiency, it achieves the comprehensive performance of compact structure and stable operation, and is suitable for various plastic foam recycling scenarios.
