Description

Technical Field

[0001] The invention belongs to the technical field of rolling mill equipment, and in particular relates to an oil stain cleaning device for a copper foil rolling mill. Background Art

[0002] During the copper foil rolling process, a large friction will be generated between the rollers and the copper foil, accompanied by a large amount of heat. By adding suitable rolling oil during the rolling process, the friction can be reduced and the rolling force of the rollers on the copper foil can be transmitted more evenly and smoothly, so that the copper foil can be subjected to more balanced force at various parts during rolling. It can also absorb and take away heat, effectively cooling the rollers, maintaining the rollers working within a relatively stable temperature range, and ensuring the stability of the rolling process.

[0003] After a long period of rolling work, rolling oil and lubricating oil for maintaining the normal rotation of each roller will accumulate, especially when mixed with impurities such as oil and dust, which will make the oil problem more prominent. If the oil adheres to the surface of the roller for a long time, it will gradually absorb more impurities such as dust and metal debris, making the surface of the roller rough and unclean. This changes the original flat and smooth state of the roller, which in turn affects the contact between the roller and the copper foil in the subsequent rolling process, which is not conducive to the uniform transmission of rolling force and the precise control of indicators such as copper foil thickness and flatness.
