Film, slitter is a large roll of paper. Non-woven fabric, aluminum foil, mica tape and other thin materials are cut into small rolls of different widths before and after printing. They are often used in papermaking machinery and printing and packaging machinery. The aggressive control scheme of the slitter is to use a large motor to drive the rewinding and unwinding shaft. A magnetic powder clutch is added to the rewinding and unwinding shaft, and the resistance generated by the magnetic powder clutch current is adjusted to control the appearance of the data. Magnetic powder clutches and brakes are a special type of automated actuators that transmit torque through magnetic powder filled in the working gap.

        By changing the magnetic current, the magnetic state of the magnetic powder can be changed, thereby adjusting the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high-speed segment fine-tuning and medium and small power speed regulation systems. It is also used to adjust the torque by adjusting the current to ensure that the tension in the winding process adheres to a constant unwinding or rewinding tension control system. The current slitting machines are all fully automatic equipment types, which is more convenient when using Del, which can make the use of them more in daily operations.
