Description

Cleaning device for sealing belt of electrolytic copper foil raw foil machine

Technical Field

The utility model relates to the technical field of electrolytic copper foil production, in particular to a cleaning device for a sealing belt of an electrolytic copper foil raw foil machine.

Background

Copper foil is an important material for manufacturing copper-clad plates and printed circuit boards, and is called a 'neural network' for transmitting and communicating signals and power of electronic products. The electrolytic copper foil is produced by an electrolytic copper foil producing machine, and the electrolytic copper foil producing machine mainly comprises an anode groove, a cathode roller, a wind-up roller and closed circulation sealing devices on two sides, wherein the closed circulation sealing devices mainly comprise sealing belts and guide wheels.

The working principle of the electrolytic copper foil production machine is that a copper sulfate solution is pumped into an electrolysis area surrounded by a cathode roller, an anode plate and sealing belts at two sides for electrolysis, and then copper deposited on the cathode roller is stripped and collected by a stripping roller.

The sealing tape plays a role in sealing and can ensure the uniformity of the side edges of the copper foil. In the actual production process, due to the action of friction force, the cathode roller rotates to drive the sealing belt to circularly rotate along the direction guided by the guide wheel, a small amount of copper sulfate solution is inevitably adhered to the sealing belt rotated out of the electrolysis area, the adhered solution is crystallized into particles in the air, when the sealing belt is rotated into the electrolysis area from the other end, the copper sulfate particles cannot be redissolved, the sealing performance is poor, meanwhile, the sealing belt is aged and deformed in an acidic environment for a long time, the sealing effect cannot be very good, and the produced copper foil is torn and burned.

There are some sealing strip cleaning devices in industry, for example, a dynamic sealing ring cleaning device for electrolytic production of copper foil (the sealing ring in the technology is equivalent to the sealing strip in the application) with publication number CN109939993a, which comprises a guiding wheel assembly, a workbench and a cleaning device, wherein the guiding wheel assembly is used for guiding the sealing ring to enter a cleaning water tank arranged at the end part of the workbench for cleaning, and a miniature vibration mechanism is further arranged on the cleaning water tank to drive the sealing ring to vibrate in the water tank so as to achieve better cleaning effect. However, after the cleaning device is used for a certain time, the concentration of the copper sulfate solution in the cleaning water tank is gradually increased, the cleaning effect is affected, and water is inconvenient to change.
