What is an automatic slitting machine? What are the advantages?

Slitter is a kind of wide paper or film slitting into multiple narrow width material machinery and equipment, commonly used in printing and packaging machinery. Previously, the magnetic powder clutch speed of the slitting machine can not be high, because in the operation of the magnetic powder easily caused by high-speed friction, resulting in high temperature, shortening its life, will seriously jam, so that the machine operation is blocked, bringing very serious consequences to the production. Seriously affect the production efficiency.
The traditional control scheme of slitting machine is to use a large motor to drive the shaft of winding and unwinding, and add a magnetic powder clutch on the winding and unwinding shaft, and control the resistance generated by adjusting the current of the magnetic powder clutch to control the tension of the material surface. The magnetic powder clutch and brake is a special automatic actuator that transmits torque through the magnetic powder filled in the working gap, and the magnetic current can be changed to change the magnetic state of the magnetic powder and thus adjust the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, and is suitable for high-speed section fine adjustment and small and medium power speed regulation system. It is also used in the unwind or rewind tension system where the torque is adjusted by means of adjusting the current to ensure that the tension remains constant during the winding process.
The main feature of the slitter is that the magnetic powder clutch acts as a resistance device and 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, which can control smaller tensions.

The utility model relates to an automatic slitting machine in which the slitting knife holder is set on one side of or between the roller mountings, and a slitting blade consisting of one or more straight blades or disc-shaped blades is also provided inside the slitting knife holder. The number of groups of the roller mount is the same as the number of groups of the feed rollers, and at least one of the feed rollers inside it has a lifting function. The feed rollers are provided on the inner and lower sides of the roller mount and are fixed to the frame in a horizontal configuration. A lifting device is provided on the upper or side of the roller mount for driving the feed rollers up and down. In the frame is also provided with a transmission device can be connected with the feeding roller. The utility model design adopts automatic cutting method, which can simultaneously slit the same or different In addition, because the upper and lower double drums or the upper and lower four roller conveying method, not only reduce the staff In addition, the upper and lower double roller or upper and lower four roller conveying method not only reduces the labor intensity of the staff
