The frequency of slitter is very high, it can cut a wide range of paper or film into a unified planning of paper or film, some paper machines or printing machines will use slitter.

Slitter is mainly through the internal motor to drive the winding shaft, and put the magnetic powder clutch on the shaft, by changing the clutch current size to adjust its resistance, so as to change the tension of the machine.
Magnetic powder clutch and brake is a kind of special automatic performance components, it is filled in the working gap of the magnetic powder transmission torque, change the excitation current can change the magnetic state of the magnetic powder, so as to adjust the transmission torque. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high-speed micro adjustment and medium and small power speed regulation system. It is also used in unwinding or rewinding tension control system to adjust torque by adjusting current to ensure constant tension during winding.
The primary characteristic of the slitter is that the magnetic powder clutch as a resistance device, through the system control, outputs a DC voltage to control the resistance of the magnetic powder clutch. The first advantage is that it is a passive device, which can control less tension.
Its primary disadvantage is that the speed can not be high. When running at high speed, it is easy to form high-speed conflict of magnetic powder, resulting in high temperature, forming magnetic powder clutch heating, thus shortening its life. It is a device used to cut a certain width of coil longitudinally into several narrow strips.
After it is installed in the calender, extruder, gluing machine and other unit devices, it can complete the continuous strip cutting, often with a winding device. Slitting knife can be used flat blade knife and round knife.
The above is Xiangqi electromechanical Xiaobian share about the slitting machine industry common sense, I hope we can love.
