Application of magnetic particle clutch in slitting machine
Slitter is a broad paper or thin film into a wide range of narrow materials of mechanical equipment, often used in paper machinery and printing and packaging machinery.
The former slitter magnetic powder clutch speed can not be high, because in the operation of the high speed friction caused by magnetic powder, resulting in high temperature, shorten its life, serious will be stuck to die, so that the machine operation is blocked, to produce serious consequences. Serious impact on productivity.
The traditional control scheme of the slitter is to use a large motor to drive the shaft of the retractable roll, and the magnetic powder clutch is added on the reel to control the resistance produced by adjusting the current of the magnetic particle clutch to control the tension of the material surface. Magnetic powder clutch and magnetic powder brake is a special automation components, it is filled in the work gap of the magnetic powder transfer torque, change the magnetic current can change the magnetic state, and then adjust the transmission torque. It can be used for stepless speed regulation from zero start to synchronous speed, and it is suitable for speed adjustment system with high section and small power. It is also used to adjust the torque by adjusting the current to ensure a constant unwinding or rewinding tension control system during winding.
