Description

TECHNICAL FIELD

[0002] At present, in the electrolytic copper foil industry, downstream lithium battery customer manufacturers have individual requirements for the width of copper foil according to the characteristics of their production lines. The green foil machine using O-ring to limit the electric field electrolysis, because the electric field is in the O-ring area on both sides of the cathode roller, the position of the O-ring is affected by the structure of the cathode roller and the anode tank, and cannot be changed after installation. Only copper foil with fixed width can be produced. The special glue coating is not limited by the structure of the cathode roller and the anode tank, and can also effectively limit the electrolytic electric field by replacing the O-ring. When the coating on the surface of the cathode roller is made, adjusting the distance between the two sides of the coating can obtain copper foil with the same width. The key to the glue coating that insulates the electric field is that it needs to be uniform in the entire circumferential range of the cathode roller surface. The characteristics are that the edge of the glue layer is neat, and the thickness and width are controllable. At present, the coating is manually scraped, and the quality of the coating cannot be controlled. The preparation, manual scraping, drying and other processes consume a lot of time and are low in process efficiency.
