The invention patent of Copper Crown Copper foil Co., Ltd. has been authorized by the State intellectual property Office.

A few days ago, Anhui Tongguan Copper foil Group Co., Ltd., "a raw foil machine winding tension control system and control method" invention patent authorized by the State intellectual property Office.

In the process of copper foil production, in order to achieve good performance indexes such as thin thickness uniformity, elongation and extensibility, the main control parameter is the winding speed, and its essence is to control the tension between the copper foil strips through the control of the winding speed. if the tension is unstable, serious quality problems of ripping, wrinkling and thickness inequality may occur in the copper foil, affecting production efficiency and product quality. Therefore, copper foil tension control is an important technology in copper foil production. However, in the case of different train speed, different copper foil thickness and different winding diameter, the tension control effect is different and can not meet the precision requirements.

The invention provides a raw foil machine winding tension control system and a control method, the tension control accuracy is accurate from the previous single digit to the two digits after the decimal point, and the tension stability is obviously improved.
