Introduce the basic content of the protective film coating machine in detail! Protective film coating machine is a mechanical device that cuts wide paper or film into multiple narrow materials, commonly used in paper making machinery and printing and packaging machinery. Previously, the speed of the magnetic particle clutch of the slitting machine could not be high, as it could easily cause high-speed friction of the magnetic particle during operation, generate high temperatures, shorten its lifespan, and in severe cases, it could become stuck, hindering machine operation and causing serious consequences for production. Serious impact on production efficiency.
The main feature of the protective film coating machine is that the magnetic powder clutch serves as a resistance device, which outputs a DC voltage through 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.
The traditional control scheme of the protective film coating machine is to use a large motor to drive the winding shaft. A magnetic powder clutch is added to the winding shaft, and the resistance generated by the magnetic powder clutch is controlled by adjusting its current to control the surface tension of the material. Magnetic powder clutch and brake are a special type of automatic actuator that transmits torque through magnetic particles filled in the working gap. By changing the magnetic current, the magnetic state of the magnetic particles can be changed, thereby adjusting the transmitted torque.
It can be used for stepless speed regulation from zero to synchronous speed, suitable for fine-tuning in high-speed sections and small to medium power speed regulation systems. It is also used to adjust the torque by adjusting the current to ensure a constant tension during the winding process in the unwinding or rewinding tension control system.
