What’s the Splitting Machine?

 

Splitting machine is a pre-press that divides a large volume of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into small rolls of different widths. Postpress equipment is commonly used in papermaking machines and printing and packaging machinery.

 

The traditional control scheme of the splitting machine is to use a large motor to drive the shaft of the retracting reel. A magnetic powder clutch is added to the rewinding reel. The resistance of the magnetic clutch is controlled by adjusting the current of the magnetic powder clutch to control the tension of the material surface. Magnetic powder clutches and brakes are a kind of special automation actuators. It transfers magnetic torque through the magnetic powder filled in the working gap, and changes the magnetic current to change the magnetic state of the magnetic powder, and then adjust the transmitted torque. Can be used for stepless speed regulation from zero to synchronous speed, suitable for high speed trimming and medium and low power speed control systems. It is also used in an uncoiling or rewinding tension control system that adjusts the torque by adjusting the current to ensure that the tension during the winding is kept constant.

Splitting machine are continuously controlled from single-motor to dual-motor, three-motor development, and are more stable and efficient at faster machine speeds. The main feature of the splitting machine is that the magnetic powder clutch acts as a resistance device. Through system control, a DC voltage is output to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device that can control less tension.

 

The disadvantages is that splitting machine can not be high speed. High-speed friction of magnetic powder is easily caused during high-speed operation, resulting in high temperature, which causes the magnetic powder clutch to heat up and shorten its service life.
