Cutting machine is a wide paper or film will be cut into many narrow the mechanical equipment used in paper-making machinery and printing and packaging machinery. Magnetic particle clutch before cutting machine speed is not above, because the run time could easily lead to high-speed magnetic friction, high temperature, shorten its life, and in severe stuck, blocked the machine running shanghai escort, to bring very serious consequences for production. Slitter traditional control scheme is to use a large-volume motor to drive the retractable shaft, the retractable reel plus a magnetic clutch, magnetic clutch by adjusting the current to control the resistance it generates to control the material surface tension. Magnetic particle clutches and brakes is a special implementation of automation components, which work by filling rubber conveyor belt in the gap of the magnetic transfer torque to change the magnetic excitation current can change the magnetic state, thereby regulating the transmission of torque.  slitting machine feature is a magnetic clutch, as the resistance device, through the system control to output a DC voltage to control the resistance generated magnetic clutch. The main advantage is a passive device that can control the small tension. Disadvantages: is not high speed, high-speed magnetic high-speed run-time could easily lead to friction, high temperature, thereby causing magnetic clutch heat shortening its life. A certain width with a tool to cut the longitudinal roll profile control, cut into several narrow sub-volume devices used. Be installed in the calendar or extrusion machine, coating machine units after installation can be completed continuously cut into strips, ultrasound machine often with a winding device. Article cutting knife can be used plain film and round the sword blade.
