Equipment Introduction

When slitting lithium battery separators, it is often found that the width of the separator is too wide or there are some defects. Improve product utilization. Combining years of production experience, our company has developed the GC450 cutting machine, which is specially used for cutting and cutting lithium battery films.


Characteristic Description

Using color touch screen and Siemens 200 series PLC, stable operation and humanized operation;

It has the functions of automatic constant tension unwinding, tapered tension control winding, fixed length (diameter) stop, and stop tension maintenance;

The variable frequency motor is used as the traction and winding drive, so that the line speed and tension of the whole machine can be dynamically and synchronously controlled automatically, and it has the characteristics of fast response and stable control;

The whole machine is designed as a whole with casters and adopts 220V power supply, which has the advantages of compact structure, convenient operation, etc. At the same time, it is flexible and convenient to move, and is not limited by the factory space and power supply conditions;
