Slitting Machines Are Often Used In Papermaking Machinery And Printing And Packaging Machinery

Slitting machine is a kind of mechanical equipment that cuts wide-width paper or film into multiple narrow-width materials. It is often used in paper-making machinery and printing and packaging machinery.

The traditional control plan of the slitting machine is to use a large motor to drive the rewinding and unwinding shaft. A magnetic powder clutch is added to the rewinding and rewinding shaft. The current of the magnetic powder clutch is adjusted to control the resistance generated by the magnetic powder clutch to control the tension on the surface of the data. . Magnetic powder clutch and brake are a kind of special automatic actuator, which transmits torque through the magnetic powder filled in the working gap. Changing the excitation current can change the magnetic state of the magnetic powder and then adjust the transmitted torque. It can be used for stepless speed regulation from zero start to synchronous speed, suitable for fine-tuning of high-speed section and speed regulation system of medium and small power. It is also used in the unwinding or rewinding tension control system that adjusts the torque by adjusting the current to ensure that the tension remains constant during the winding process.

The main feature of the slitter is that the magnetic powder clutch is installed as a resistance, and after system control, it outputs a DC voltage to control the resistance generated by the magnetic powder clutch. The main advantage is that it is passively installed and can control less tension.

The main drawback is that the speed cannot be high, and high-speed friction of magnetic powder is easily formed during high-speed operation, resulting in high temperature, forming the magnetic powder clutch to generate heat and shorten its life.

Use a cutter to cut a certain width of the coil longitudinally and cut it into several narrower coils for installation.

After installing it on a calender, extruder, glue applicator and other units, it can complete continuous cutting, often with winding installation. The slitting knife can be a flat knife and a round knife.
