Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of squeezing rollers, in particular to a vacuum squeezing roller and a process method thereof. BACKGROUND

[0002] The main method of electrolytic copper foil is to reduce copper ions in copper sulfate solution into copper single element by current through cathode roller and anode plate respectively, so that copper single element generates copper foil on the cathode roller. This process will inevitably cause copper sulfate solution to remain on the generated copper foil. Although the acid solution is filtered, some impurities such as metal single element and diatomite will still remain on the surface of the copper foil. If the residual acid solution is not cleaned in time, it will cause serious oxidation on the surface of the copper foil, affecting the subsequent process production.

[0003] In the prior art, the acid solution remaining on the surface of the copper foil is cleaned by a squeezing roller and a squeezing water roller. The squeezing roller used is mostly a rubber squeezing roller. The use of the rubber squeezing roller has the following problems: first, the squeezing of the copper foil surface will have residual water, which will still cause white printing, oxidation and other situations; second, the squeezing force between the squeezing roller and the cathode roller is not easy to adjust and use, and the copper foil is easily deformed due to excessive squeezing force; third, during the process of the copper foil, the water after squeezing directly flows into the electrolytic tank, causing the concentration of the copper sulfate solution to decrease, affecting the production of electrolytic copper foil. Therefore, a squeezing roller and a process method thereof are proposed to solve the above problems. SUMMARY
