[0002] Material rolls such as paper rolls or film rolls need to be sleeved on a shaft rod, and the rotation of the material roll is realized by the rotation of the shaft rod, so as to realize the extraction of the material. However, the loading and unloading of the existing material roll on the shaft rod requires manual shaft threading and then locking the shaft sleeve to complete the operation. After frequent production use, the manual labor is large. It is both complicated and has great potential safety hazards for manual shaft threading in a limited space, and it wastes time, which is not conducive to the automated operation of the whole machine. During the shaft threading process, the disassembly convenience of the bearing end of the winding shaft will directly affect the docking efficiency. How to use equipment drive to drive the shaft threading action of the bearing end of the winding shaft in a limited space.
