As the name suggests, the slitter is a machine that slits plastic films, composite films, webs, and the like. Its invention greatly facilitates people's life and production, and is therefore deeply loved by the public. Let's take a look at the slicer.

The slitting machine is a pre-pressing and post-pressing device that divides a large roll of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into small rolls of different widths. It is commonly used in paper machinery and printing and packaging machinery.

In the past, the speed of the magnetic powder clutch of the slitter is not high, which is easy to cause high-speed friction of the magnetic powder, resulting in high temperature, shortening the life, and being stuck in a serious situation, hindering the operation of the machine and causing serious consequences to the production.

Seriously affect production efficiency. The double frequency conversion motor is used to control the friction of the magnetic powder to a certain value when the diameter of the coiling material becomes large. There will be no high temperatures.

The traditional slitter control scheme uses a large motor to drive the coiler and a magnetic powder clutch on the coiler. By adjusting the current of the magnetic powder clutch, the resistance generated by the magnetic powder clutch is controlled to control the tension of the material surface. Magnetic powder clutches and brakes are dedicated automatic actuators. They transfer torque through the magnetic powder filled in the working gap. By changing the magnetic field current, the magnetic state of the magnetic powder can be changed, and the transmission torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous, high speed segment fine adjustment, medium and small power speed control system. It also adjusts the torque by adjusting the current to ensure that the unwinding or rewinding tension control system has a constant tension during winding.

The slitting machine has been continuously developed from single motor control to dual motor and three motor control. It is more stable and efficient in the case of faster machine speed.
