Description

technical field [0001] The invention relates to the technical field of slip shafts, in particular to a slip shaft with adjustable tension. Background technique [0002] The slip shaft, also known as the friction shaft, has a special structure and consists of multiple slip rings. It is mainly used in the rewinding shaft of the slitting machine, and it is also used in the unwinding shaft in special occasions. The purpose is to use the principle of slipping of each slip ring on the slip shaft to make multiple rolls on the shaft maintain constant tension for rewinding and unwinding. . [0003] In the Chinese invention patent with the application number CN201721824161.8, a slip shaft with a single air path structure is disclosed, including a retaining ring, a slanting block and an expansion sleeve. One end of the retaining ring is embedded with one end of the slanting block, and the retaining ring A bearing is fixedly installed inside one end, and an expansion sleeve is install...
