Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil production equipment, in particular to a pressure regulating device which can be quickly disengaged. Background Art

[0002] As an important material in the electronics industry, electrolytic copper foil is widely used in home appliances, communications and other fields. It is a copper processing material with a high technical level. In the copper foil production process, after the cathode roller of the raw foil machine is electroplated, the semi-finished copper foil needs to be sprayed with liquid, washed with water, squeezed with a water squeeze roller and dried with a hot air blower in sequence, and then continuously peeled off from the cathode roller to obtain the rough foil.

[0003] In the lithium battery foil production machine, a pressure roller is needed to squeeze out the liquid on the copper foil. In order to adapt to different copper foil specifications, processes and line speeds, different pressing pressures need to be adjusted. At the same time, in order to meet the requirements of foil penetration, the pressure roller needs to be able to be quickly disengaged and restored.

[0004] If the pressure is too high or too low, or fluctuates, the copper foil may not be squeezed dry, yellowing, deviation, folding and other defects may occur, resulting in waste. The foil threading process requires manual roller lifting, which is time-consuming and labor-intensive. Generally, two people are required to lift the roller, which adds extra manpower. Currently, two methods are generally used: 1. Self-weight pressing method; 2. Combination of cylinder pressing and self-weight method.

[0005] In the prior art: 1. The pressing method using the deadweight of the pressing roller has several disadvantages: 1. When adjusting the pressure, the pressing roller or the counterweight generally needs to be replaced, and it cannot be adjusted quickly; 2. It needs to be stopped for replacement, and it cannot be fine-tuned online, and it cannot be adjusted to near-zero pressure; 3. When threading the foil, people need to manually lift the pressing roller, which is laborious.

[0006] Second, the method of combining cylinder compression with deadweight is adopted, and the pressure is fine-tuned by the pressure regulating valve. The cylinder maintains ventilation state for a long time. There are several disadvantages: 1. Pressure fluctuations caused by air pressure fluctuations have poor reliability; 2. When used on a large scale, the consumption of compressed air is large. Utility Model Content
