Principle Of Slip Shaft

Slip shaft, also known as friction shaft. It is applied to the winding shaft of the slitting machine, and also used for the unwinding shaft in special occasions. The purpose is to use the principle of the slippage of each slip ring on the slip shaft, so that multiple rolls on the shaft can always maintain constant tension for winding and unwinding.

The slip shaft has a special structure and is composed of multiple slip rings, which can overcome the above phenomenon. When working, the slip ring is controlled to slip with a certain slip torque value (torque), and the amount of slip just compensates for the resulting speed difference, so as to precisely control the tension of each roll of material, and it can be coiled with constant tension to ensure the coiling quality.

The use of the slip shaft, the speed of the slitter, the precision of the winding, the degree of automation, the reduction of preparation time, and the improvement of the humanization of the operation can be realized. In particular, a variety of cast polyester thin materials with poor stretch resistance and large thickness errors use slip shafts to reduce the difficulty of winding. The application of slip shaft winding of precious material metal foil greatly improves the rate of authenticity and reduces production costs. Special production costs. Special paper is the earliest application of this technology.

The slip shaft has been widely used in plastic film (including electronics, capacitors, battery film, cling film, packaging, composite film); metal foil (copper foil, aluminum foil, etc.); paper rolls; slitting and rewinding of PVC sheet materials . At present, it is continuously extending to other fields, other industries, and the slitting and rewinding of other special materials. There are central winding, surface winding and surface center winding. There are four main structural forms: central air pressure slip shaft, pneumatic side pressure slip shaft, mechanical side pressure slip shaft, and air expansion shaft.
