Laminating stripping slitter

Diaphragm slitting machine is one of the key equipment in the production process of lithium battery material diaphragm, and its working mode is to use an upright tool to cut a certain width of the coil diaphragm into several narrow diaphragm films. The traditional control scheme of diaphragm scutters is to use a large motor to drive, add a magnetic powder brake on the reel, and control the resistance generated by adjusting the current of the magnetic powder brake to control the tension on the surface of the material. Magnetic powder brake is a special automatic actuator, which transmits torque through the magnetic powder filled in the working gap. Changing the excitation current can change the magnetic state of the magnetic powder, and then adjust the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, suitable for high-speed section fine tuning and small and medium power speed regulation system. Also used in unwinding or rewinding tension control systems that adjust torque by adjusting current to ensure constant tension during winding.

The main feature of the diaphragm slitter is that the magnetic powder clutch is used as a resistance device, which is controlled by the system to output a DC voltage and control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device and can control less tension.

Its main disadvantage is that it can not meet some high speed tension control, and it is easy to cause high speed friction of magnetic powder when running at high speed, resulting in high temperature, resulting in heating of magnetic powder clutch and shortening its life.

The diaphragm slitter is only one kind of slitter machine, and it can also be used for slitter of paper products, plastics and composite films. Shenzhen Hengjie Automation Co., Ltd. slitter machine is the best among many manufacturers, can be designed according to different products, different requirements for customers.
