Difference between slip shaft and common air expansion shaft

The expansion pad of common air expansion shaft is a long strip through the shaft without section, so it has no slip function. When cutting multiple strips, there is no corresponding slip action due to the change of material tension. When the tension changes or the material thickness is uneven, it is easy to cause uneven winding, broken strip, loose coil and uncoiling, resulting in material loss. The speed of winding line is low, the work efficiency is poor, and the same axis can't pick up large and small coils at the same time.

Structural characteristics and principle of sliding gas expansion shaft

Slip shaft, also known as slip type gas expansion shaft, is a special segmented, independent slip and torque setting structure. It can process the uncoiling scene of each volume of data due to the uneven thickness and tension, and can effectively improve the product quality and work efficiency

Structural features and principle of slip type inflatable shaft: the slip type inflatable shaft mainly consists of mandrel, air bag, slip sleeve and other parts. Air enters into the air bag to form air inflation, which pushes each torque group to expand outward. The sliding torque value of each torque group is set according to the size of inflation pressure, which is convenient for controlling the tension adjustment of each roll of data on the slitter

Sliding expansion shaft is mainly used for slitting equipment with high quality and high speed

Technical parameters of slip type air expansion shaft: outer diameter of main body of slip type air expansion shaft is Φ 75mm, action outer diameter is Φ 78mm, applicable to paper tube of Φ 76 ± 0.2mm
