What is the Automatic Slitting Machine?

  • March 10, 2022

The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding and unwinding, and a magnetic powder clutch is added to the reeling and unwinding shaft. The resistance generated by the magnetic powder clutch is adjusted to control the surface tension of the material. . Magnetic powder clutches and brakes are special automatic actuators. They transmit torque through 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 to synchronous speed, suitable for fine-tuning of high-speed section and speed regulation system of medium and small power. It is also used for 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 slitting machine is that the magnetic powder clutch acts as a resistance device, which is controlled by the system to output a DC voltage to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device and can control less tension. Its main disadvantage is that the speed cannot be high, and it is easy to cause high-speed friction of the magnetic powder during high-speed operation, resulting in high temperature, causing the magnetic powder clutch to heat up and shorten its life.

advantage
1. Stable operation: the reeling of the paper is firm, the two sides are flat, and the noise is low.
2. Easy to operate: both sides of the paper tape after slitting are smooth and flat, without burrs.
3. Strong adaptability: the width of the upper and lower knives can be adjusted arbitrarily between 2 - 1700mm.
4. High output: the output of a single machine can be used by 3 coiling machines.
Precautions
1. Before starting the machine, ensure that the voltage, current and hydraulic pressure are correct and stable.
2. Before the equipment is ready to run, all personnel must be notified to leave the equipment to ensure personal safety before starting the operation.
3. When running, do not touch the running film roll or roll core with your hands, so as to avoid personal injury caused by hand involvement.
4. During the operation, do not scratch or cut the roller cores with knives or hard objects.
Maintenance
1. Oil circuit
2. Mechanical angle

3. Electrical aspects

4. Gas path
