|The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the reel and reel, and the resistance generated by the magnetic clutch is controlled to control the tension of the surface of the material. Magnetic powder clutches and brakes are special automatic actuators that transmit torque through the magnetic powder filled in the working gap. The magnetic current can be changed to change the magnetic state of the magnetic powder, and then the transmitted torque can be adjusted. Slitting machine can be used for stepless speed regulation from zero to synchronous speed. Slitting machine is suitable for high speed section fine adjustment and medium and small power speed control system. Slitting machine is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with a constant tension during winding.|
The slitting machine continuously controls from single motor to double motor, and the three motors develop more stable and efficient when the machine speed is faster.
The main feature of the slitting machine is that the magnetic powder clutch acts as a resistance device and outputs a DC voltage through the system control to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device that can control small tensions.
