Automatic cutting machine is a kind of mechanical equipment that cuts wide paper or film into multiple narrow materials, and is often used in papermaking machinery and printing and packaging machinery. Automatic slitting machine function parameters Automatic slitting machine slitting speed (min) 300m The machine is controlled by double frequency conversion motors, one is the main motor and the other motor controls two rewinding shafts.

The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding and unwinding, and a magnetic powder clutch is added to the reeling and unwinding shaft. The resistance generated by the magnetic powder clutch is adjusted to control the surface tension of the material. . Magnetic powder clutches and brakes are special automatic actuators. They transmit torque through magnetic powder filled in the working gap. Changing the magnetic current can change the magnetic state of the magnetic powder, thereby adjusting the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, suitable for fine-tuning of high-speed section and speed regulation system of medium and small power. It is also used for the unwinding or rewinding tension system that adjusts the torque by adjusting the current to ensure that the tension remains constant during the winding process.
