The coordination between each component of the slitting machine is also relatively important

The use of slip axis can improve the speed, winding accuracy, automation level, preparation time reduction, and humanization of operation of the slitting machine. Especially for various cast polyester thin materials with poor tensile strength and large thickness errors, the use of slip shafts reduces the difficulty of winding. The use of slip axis winding for precious metal foil greatly improves the yield of genuine products and reduces production costs.

The slip shaft is centered around a precision hollow core ventilated main shaft, which uses compressed air to push the piston inside the cavity, causing the shaft core to generate frictional torque between the friction piece and the slip ring, further driving the inclined expansion plate on the inclined base to expand in the outer diameter direction, squeezing the winding drum, and transmitting the torque of the winding drum, thus achieving constant tension winding.

The structure of the slip shaft is special, consisting of multiple slip rings. During operation, the slip rings are controlled to slip with a certain slip torque value (torque), and the slip amount compensates for the speed difference generated, thereby accurately controlling the tension of each roll of material and ensuring constant tension winding, ensuring the quality of winding. Can be applied in the range of low to high tension, suitable for high speed, large material thickness error, multi-stage tension control, high tension control accuracy, and requirements for neat end face winding. So, the air expansion unit of the slip shaft plays a very important role, consisting of a cavity, a slanted base, a piston, an air seal, bearings, springs, and expansion plates. The coordination between each component is also relatively important.
