Control scheme of slitting machine:
A large motor is used to drive the shaft of the rewinding and unwinding reel, and a magnetic particle clutch can be added to the rewinding and unwinding reel, and the current of the magnetic particle clutch is dispatched to control the resistance of the material to control the tension of the material surface. The clutch and brake along the magnetic powder is a special automatic fulfillment part, which is to change the magnet flow by transferring torque through the magnetic powder that fills the working gap to change the magnet state of the magnet powder, and then adjust the transmitted torque. It is suitable for fine-tuning of high-speed sections and speed regulation systems for small and medium-sized electric power. The torque is adjusted according to the amount of applied current to ensure that the support force in the whole process of the inverter adheres to a smooth opening or rewinding tension control system software.
Unwinding tension detection system of slitting machine:
Tension sensor detection is a direct detection of tension, tightly combined with machinery, and a detection method of moving parts. Usually two sensors are paired and mounted on the end shafts on both sides of the inspection roller. After detecting the applied load on both sides of the guide roller, the tension sensor sensitive element is displaced or deformed, and then the actual tension value is detected, and the tension data is converted into a tension signal and fed back to the tension controller.
