Slitting machine is a large roll of paper, film, non-woven cloth,aluminum foil,mica cut into small rolls of different widths before and after the thin material,printing equipment ,often used in paper making machinery and printing packaging machinery.
The traditional control scheme of the cutting machine is ti use a large motor to drive the retractable and retractable shaft.Magnetic powder clutch is added to the telescopic scroll to control the resistance of the electromagnetic clutch by adjusting the current,so as to control the tension on the material surface.Electromagnetic clutch and brake is a special kind of automatic actuator,it is through filling in the working gap of magnetic powder transfer torque,change the magnetic current can change the magnetic state of magnetic powder,so as to adjust the transfer of torque,Can be used from zero to synchronous speed stepless speed regulation,suitable for high speed fine adjustment and small and medium power speed regulation system. An unwindng or rewinding tension control system in which torque is adjusted by adjusting current to ensure constant tension during winding.
