Slitting machine is a large roll of paper, film, mica tape and other thin materials into different widths of small rolls prepressed, commonly used in paper machinery and printing and packaging machinery.
The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding and unwinding, adding a magnetic powder clutch to the retracting and unwinding reel, and controlling the resistance generated by adjusting the current of the magnetic powder clutch to control the tension on the surface of the material.
The slitting machine can be used for stepless speed regulation from zero start to synchronous speed, suitable for high-speed section fine-tuning and medium and small power speed regulation system. The slitter is also used to adjust the torque by adjusting the current to ensure that the tension remains constant during the winding process.
The main feature of the slitting machine is that the magnetic powder clutch is used as a resistance device, which is controlled by the system to output a DC voltage and control the resistance generated by the magnetic powder clutch. The main advantage of the slitter is that it is passive and can control small tensions.
Ribbon slitters are key equipment in the label printing and packaging industry for slitting wide ribbons to the required width.
