The traditional control scheme of the fabric slitting machine is to use a large motor to drive the rewinding and unwinding shaft, and a magnetic powder clutch is added to the rewinding and unwinding reel, and the resistance generated by the magnetic powder clutch is controlled by adjusting the current of the magnetic powder clutch to control the surface of the material tension.
Through the description of the cloth slitting machine, we know that the key of the slitting machine is “cutting”. Since most raw materials, including wood, metal, paper, film, cloth, aluminum foil, etc., need to be cut by the cloth slitter, the cloth Slitters are used in a wide range of applications.
The working principle of the fabric slitting machine: the fabric slitting machine is a kind of mechanical equipment that cuts wide paper or film into multiple narrow width 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 machine cannot be high, because it is easy to cause high-speed friction of the magnetic powder during operation, resulting in high temperature and shortening its life. Seriously affected the production efficiency. The traditional control scheme of the fabric slitting machine is to use a large motor to drive the rewinding and unwinding shaft, and a magnetic powder clutch is added to the rewinding and unwinding reel, and the resistance generated by the magnetic powder clutch is controlled by adjusting the current of the magnetic powder clutch to control the surface of the material. tension. Magnetic powder clutches and brakes are special automatic actuators. The fabric slitting machine 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 to synchronous speed, suitable for high-speed fine-tuning and small and medium power speed regulation systems. It is also used to adjust the torque by adjusting the current to ensure that the tension remains constant during the winding process. Unwinding or rewinding tension control system.
