6 Inch Key Type Friction Air Shaft

Description

Introduction:

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

The slitting machine is a device that cuts a roll of web material into multiple rolls, and it is widely used. The function of the rewinding shaft is to wind the multi-reel material after various materials into strips, from the core to the outer layer, evenly, neatly, and wound on one or two shafts with constant tension. However, due to the uneven thickness of the material itself, there is a certain thickness error. After the coil is continuously coiled, the diameter of each coil has a larger accumulated error. This leads to a greater difference in the winding speed of each strip, and a greater difference in tension. It causes uneven tightness of the coil and uneven end faces. In severe cases, the material is damaged and scrapped due to excessive tension, especially the polyester film, which not only has a large thickness error, but also has a large elongation, which is easy to stretch and deform and cause waste.

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 accurately control the tension of each roll of material, and it can be coiled with constant tension to ensure the coiling. quality.
