What is the slip shaft in the slitter machine?

November 27,2021

Many friends may know what is the slitter, but if you say to your friends slip shaft do you know? I am sure your friend will answer no!


This article is written today mainly to let you know that the slip shaft is actually essential in our life, in a variety of machines is a necessary part, first we first understand what is the slitter.

Slitter is a wide paper or film slitting into multiple narrow material machinery and equipment, commonly used in paper machinery and printing and packaging machinery. Previously, the slitter’s magnetic powder clutch speed 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, serious jamming, 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 to adjust the torque by adjusting the current to ensure that the tension remains constant during the winding process of the unwind or rewind tension control system.

After understanding the slitting machine, let’s look at the slip shaft in the slitting machine is mainly used for what. Slip shaft, also known as friction shaft. Used in the slitter to wind up the shaft, special occasions are also used for the release of the shaft, the purpose is to use the slip shaft on each slip ring slip principle, so that the shaft of multiple reels of material, always maintain a constant tension to wind.
