Foil producing machine preventing copper foil white spot forming

Abstract

The invention discloses a foil producing machine preventing copper foil white spot forming. The foil producing machine comprises an electrolytic cell. An anode plate and a cathode roller are arranged in the electrolytic cell. A copper foil winding device is arranged on the right side of the cathode roller. A liquid spraying pipe is arranged on the side face of an inlet of the cathode roller. A plurality of circular holes arranged at equal intervals are formed in the liquid spraying pipe. The foil producing machine has the beneficial effects that the liquid spraying pipe covering the roller face width of the cathode roller is arranged above an ordinary cathode roller, and before the cathode roller enters the electrolyte face, the roller face of the cathode roller is completely covered with an electrolyte solution, and the possibility of overflow liquid foam pollution is eliminated from the source. The structure is simple, generation of electrolysis copper foil white spots can be effectively prevented, the time of oxidization of the roller face of the cathode roller can be prolonged as well, the grinding frequency of the cathode roller is reduced, and the service life of the cathode roller is prolonged.

Description

technical field [0001] The invention relates to the field of production equipment of electrolytic copper foil, in particular to a foil machine for preventing the formation of white spots on copper foil. Background technique [0002] Copper foil is an important material for the manufacture of copper clad laminates and printed circuit boards. In the rapid development of today's electronic information industry, electrolytic copper foil is known as the "neural network" of electronic product signal and power transmission. Electrolytic copper foil is mainly produced by using a raw foil machine. At present, the existing raw foil machine mainly includes a frame, an electrolytic cell, an anode plate, a cathode roller and a winding roller. The anode tank is installed on the frame, and the anode plate is located on the anode. In the tank, the cathode roller is installed above the anode tank. The working principle of the electrolytic copper foil raw foil machine is: when the raw foil ...

AI Technical Summary

Problems solved by technology

[0003] In the production of electrolytic copper foil in the existing raw foil machine, when the cathode roll surface enters the electrolyte liquid surface, it is easily polluted by the overflow liquid foam, and corresponding white spots are formed on the surface of the electrolytic copper foil. In order to solve this problem, eliminate White spot, it is necessary to develop a foil machine to prevent the formation of copper foil white spot
