Copper foil pressing roller device and copper foil winding method of copper foil dividing and cutting machine

Abstract

The invention relates to a copper foil pressing roller device and a copper foil winding method of a copper foil dividing and cutting machine. The device is arranged on the copper foil dividing and cutting machine and comprises a short foil pressing roller with the length being smaller than the width of a copper foil finished product, and a long foil pressing roller with the length being larger than the width of the copper foil finished product; and 45-degree chamfers are arranged at two end parts of the axial direction of the short foil pressing roller. The copper foil winding method of the copper foil dividing and cutting machine comprises the steps of (1) after upcoiling a copper foil, using the short foil pressing roller with the length being smaller than the width of the copper foil finished product for winding through the cooperation of appropriate speed and tensile force; (2) after operating for a certain time, adjusting the tensile force, and increasing the speed to the target speed; and (3) after finishing winding, using the long foil pressing roller with the length being larger than the width of the copper foil finished product for carrying out appearance treatment on an underwind finished product. According to the copper foil pressing roller device and the copper foil winding method of the copper foil dividing and cutting machine provided by the invention, the problemthat the length of the foil pressing roller is not matched with the width specification of the copper foil finished product is solved, the abnormal problems such as creases, horizontal edge marks andscaly figures are effectively solved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil slitting, in particular to a copper foil pressing roller device of a copper foil slitting machine and a copper foil winding method. Background technique [0002] The foil roller for copper foil slitting machine is made of nitrile rubber material. During the winding process of the finished copper foil, it relies on its own weight to squeeze out the air between the foil surfaces and roll the foil surface flat. It is a device that cooperates with the appropriate speed and tension to make the finished copper foil meet the production and use requirements. [0003] In the current production process, due to the randomness of the width of the finished copper foil, the length of the foil pressing roller for winding of the slitter cannot match it. When the length of the foil pressing roller is greater than the width of the finished copper foil, the weight of the foil pressing roller will c...

AI Technical Summary

Problems solved by technology

At present, the production can only use foil pressing rollers whose length is close to the width of the finished copper foil. When the speed is >30m / min, the finished product is prone to discounts, horizontal edges, fish scales and other abnormalities, which will seriously affect the product quality and output; The huge number of finished copper foil widths leads to an astonishing purchase of foil rollers, which increases production costs and causes huge losses to the company
