40Khz Ultrasonic fabric cutting device for roller blinds cutting

Description

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.

Slitting machine is a kind of mechanical equipment that cuts wide paper or film into multiple narrow materials, and is often used in papermaking machinery and printing and packaging machinery.
In the past, the speed of the magnetic powder clutch of the slitting machine could not be high, because it was easy to cause high-speed friction of the magnetic powder during operation, resulting in high temperature and shortening its life. Seriously affect the production efficiency. 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.
Disadvantage: 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, which will cause the magnetic powder clutch to heat up and shorten its life.
A device used to longitudinally cut a certain width of the coil with a knife and cut it into several narrower coils. After it is installed in a unit device such as a calender, an extruder, and a gluing machine, it can complete continuous strip cutting, often with a winding device. Slicing knives can be used with flat blade knives and round knives. Slitting machine series products of paper processing machinery: paper slitting machine, small paper slitting machine, web slitting machine, high-speed slitting machine, etc.
