Torque strength controllable type knitted material winder

The invention relates to the technical field of knitted material winders, and discloses a torque strength controllable knitted material winder which comprises a hollow rotating structure, a plurality of air pressure type telescopic structures and a plurality of friction type linkage structures. According to the torque-strength-controllable knitted material winder, the wound knitted material and the driving motor are in a movable abutting connection state, the pressure between abutting connection parts is controllable by means of the large-range compressibility of high-pressure gas, and once the phenomenon that the traction force is too large occurs in the winding process, the wound knitted material can be prevented from being damaged. According to the technical scheme, relative rotation can be generated between driving rotation of the driving motor and driven rotation of the winding wheel, the rotation can enable the knitting materials to be subjected to rotary traction at the torque strength of a fixed value
