Cleaning mechanism of copper foil crude foil engine

Abstract

The invention relates to the technical field of copper foil production, in particular to a cleaning mechanism of a copper foil crude foil engine, which comprises a rack, a copper foil stripping roller, a copper foil winding roller, an edge cutting mechanism and cleaning mechanisms, each cleaning mechanism comprises a collecting tank, an air compressor and a suction nozzle, the collecting tank comprises a tank body, a Venturi assembly and a negative pressure generating head, and the air compressor is connected with the negative pressure generating head. The suction nozzle is communicated with the copper foil powder inlet of the tank body through the adsorption pipeline, the negative pressure generating head is arranged at the top of the tank body, the Venturi assembly is fixedly arranged in the tank body and the negative pressure generating head, the side part of the Venturi assembly is provided with a compressed air inlet, the bottom of the Venturi assembly is provided with a copper foil powder suction inlet, the filter screen cylinder is fixedly arranged at the copper foil powder suction inlet, and the air compressor is communicated with the compressed air inlet. The device provided by the invention is simple in structure and low in cost, can effectively remove powder adsorbed on the copper foil, is relatively environment-friendly, and does not influence the surrounding environment.

Description

Technical field [0001] The invention relates to the technical field of copper foil production, and in particular to a cleaning mechanism of a copper foil making machine. Background technique [0002] Copper foil is a cathotic electrolytic material. It can be deposited on the base layer of the circuit board, bonded to the insulating layer, accept the printed protective layer, and form circuit patterns after corrosion. It can also be widely used in lithium battery products. It has the advantages of good conductivity, small size and light weight. [0003] In the traditional copper foil production process, the edges of the copper foil after being peeled off by the peeling roller have defects such as unevenness or curling, and both sides need to be cut off by an edge cutting mechanism. However, there will be a lot of copper foil powder adsorbed on the copper foil at the edge after cutting. If it is rolled up without cleaning, it may cause risks such as copper foil penetration, t...

AI Technical Summary

Problems solved by technology

With the method of brush cleaning, the brush must be in contact with the copper foil and exert a certain pressure on the copper foil to clean up the powder adsorbed on the copper foil. The powder adhering to the brush is also easy to damage the copper foil. affect surface quality

Although the powder is cleaned from the copper foil by purging, it is easy to affect the surrounding environment and affect the health of the operators

Cleaning by spraying clean water not only wastes water, but also needs to recycle the cleaned liquid. The equipment is more complicated and the cost is relatively high.
