|A slitting machine is a mechanical device that slits wide sheets of paper or film into a plurality of narrow web materials and is commonly used in printing and packaging machinery. In the past, the speed of the magnetic powder clutch of the slitting machine could not be high, because it would easily cause high-speed friction of the magnetic powder during operation, generate high temperature, shorten its life, and it would be stuck in serious cases, which would hinder the operation of the machine and bring serious consequences to the production. Seriously affected production efficiency.|
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 material surface. 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. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed section fine adjustment and medium and small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension system with constant tension during winding.
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.
