Copper-clad plate leftover material crushing and recycling device

Abstract

The invention discloses a copper-clad plate leftover material crushing and recycling device which comprises an equipment body, the equipment body comprises a crushing assembly used for crushing copper-clad plate leftover materials, and the crushing assembly is internally provided with a crushing part; the sorting and recycling assembly is used for sorting and recycling the materials crushed by the crushing assembly, and a telescopic piece used for controlling the crushing piece to move up and down is arranged in the sorting and recycling assembly; by arranging the equipment body, a user can control a telescopic piece to operate, a driving cylinder drives a telescopic rod to extend, a fine adjustment piece, a mounting frame and a crushing piece are driven to integrally move upwards, and a driving crushing roller and a driven crushing roller move to the position above the outer side of the crushing box; a user can conveniently clean crushed fine materials attached to the outer sides of the driving crushing roller and the driven crushing roller, and follow-up normal use of the driving crushing roller and the driven crushing roller is guaranteed.

Description

technical field [0001] The invention relates to the technical field of recycling devices, in particular to a device for crushing and recycling copper clad laminate scraps. Background technique [0002] Copper clad laminate is a kind of plate material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing, referred to as copper clad laminate. Various printed circuit boards with different forms and functions are selectively processed, etched, drilled and copper-plated on the copper clad laminate to make different printed circuits. It mainly plays the role of interconnection, insulation and support for the printed circuit board, which has a great influence on the transmission speed, energy loss and characteristic impedance of the signal in the circuit. Therefore, the performance, quality, manufacture of the printed circuit board The processability, manufacturing level, manufactur...

AI Technical Summary

Problems solved by technology

[0003] Copper-clad laminates are used in the production process of printed circuit boards to produce more scraps, and the copper on the scraps can be recycled. The current practice is to collect the scraps of copper-clad laminates produced in the production of printed circuit boards and use chemical replacement. Or the method of physical separation after crushing for recycling. When using the physical crushing and separation method for recycling, the copper clad laminate is broken and torn by the crushing roller. However, during the crushing process, friction generates heat, and the resin in the copper clad laminate melts. The finely crushed materials will adhere to the crushing rollers, which will affect the normal crushing effect of the crushing rollers, and seriously cause the internal blockage of the crushing equipment and burn the motor. However, the current crushing rollers are all installed inside the equipment, and it is difficult to prevent them from sticking to the outside. The material is cleaned up, and the actual use effect of the device is poor
