| Cutting machine is a kind of wide paper or film cutting into several narrow materials, mechanical equipment, often used in paper making machinery and printing and packaging machinery. Before cutting machine of magnetic powder clutch speed can not high, because of the magnetic powder at runtime high-speed friction, produce high temperature, shorten its life, serious stuck, when they make the machine run, have serious consequences for production. The serious influence production efficiency. Traditional control scheme of the cutting machine is the use of a large rolling shaft, motor to drive on and scroll with magnetic powder clutch, by adjusting the current of magnetic powder clutch to control the resistance, to control the tension of the material surface. Magnetic powder clutch and brake is a special kind of automation equipment, it is work by filling the gap magnetic powder transmission torque, changed the magnetic current can change the state of magnetic powder, and then adjust the transmission of torque. Can be used to start from scratch to synchronous speed stepless speed regulation, suitable for high speed period of fine-tuning and small and medium-sized power speed regulation system. Is also used to use the method of adjusting the current adjust torque to ensure the uncoiling of winding tension in the process of constant or rewinding tension control system. Cutting machine is the main characteristics of magnetic powder clutch as a resistance device, through the system control, a dc voltage to the output, control the resistance of the magnetic powder clutch. The main advantage is the passive device, can control the tension of smaller. Disadvantages: speed is not high, high speed magnetic powder high-speed friction caused by the runtime easily, produce high temperature, magnetic powder clutch fever and shorten its life. |
