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.

In the past, the magnetic powder clutch speed 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 slitter 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 magnetic powder filled in the working gap. Changing the excitation current changes the magnetic state of the magnetic powder and adjusts the transmitted torque. 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 control system with a constant tension during winding.

The main feature of the slitter 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.
Disadvantages: The speed is not high, and the high-speed friction of the magnetic powder is easy to occur at high speed, which causes high temperature, which causes the magnetic powder clutch to heat up and shorten its life.
The cutter is used to cut a certain width of the web longitudinally and cut into a plurality of devices for narrower slits. After being installed in a unit such as a calender or an extruder or a gluing machine, continuous cutting can be completed, often with a winding device. The knife can be used with a flat knife and a round knife.
Paper cutting machine series of cutting machine products: paper slitting machine, small paper cutting machine, web cutting machine, high speed slitting machine, etc.
Metal processing machine slitting machine: strip slitting machine, copper sheet slitting machine, aluminum sheet slitting machine, stainless steel slitting machine, tinplate slitting machine, etc.

Classification of slitting machine
The types of slitting machines are increasing, and the classification methods are also different. According to the requirements of the size of the paper, it can be divided into a paper slitter and a small paper slitter.
