Slitting machine is a kind of mechanical equipment for slitting wide sheets of paper or film into a plurality of narrow-width materials, which are commonly used in papermaking machinery and printing and packaging machinery. The speed of the front slitting electromagnetic clutch can not be high, because it is easy to cause high-speed friction magnetic powder during operation, high temperature, shorten its service life, and severely lock up, the machine operation is blocked, to produce very serious consequences. A serious impact on productivity.
The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the telescopic 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 a special type of automatic actuator that transmits torque through magnetic powder filled in the working gap. Changing the magnetic current can change the magnetic state of the magnetic powder and adjust the torque transmission.
It can be used for stepless speed regulation from zero to synchronous speed. For fine adjustment, high power section of small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with constant tension during winding.
The main feature of the slitting machine is that the magnetic powder clutch is controlled as a resistance device system to output a DC voltage and control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device, and the tension can be controlled small.
Disadvantages: The speed is not high, high-speed friction of the magnetic powder is easy to occur at high speed, and the high temperature causes the magnetic powder clutch to heat up and shorten its life.
As the web tool has a certain width, the profile is cut longitudinally and cut into a number of narrower tapping devices. It is installed in a calender or extruder, after the glue and other battery devices, usually after a continuous cutting, a winding device is usually used. A flat blade cutter and a round knife can be used.
