Slitter is a mechanical equipment to slit wide rolls of paper, film, non-woven fabrics and other materials into wide and narrow rolls of materials, commonly used in paper making machinery and printing and packaging machinery and paper tube production. The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding, in the rewinding and unwinding of the shaft with a magnetic powder clutch, by adjusting the current of the magnetic powder clutch to control the resistance it produces, in order to control the tension of the material surface. Powder clutches and brakes are a special type of automated actuating element that transmits torque through the magnetic powder that fills the working gap. Changing the excitation current changes the magnetic state of the magnetic powder, which in turn regulates the torque transmitted. It can be used for infinitely variable speed regulation from zero to synchronous speed, and is suitable for fine tuning in high speed section and small and medium power speed regulation system. It is also used in unwinding or rewinding tension control system that regulates the torque by adjusting the current to ensure that the tension remains constant during the winding process.
