[0002] Slitting machine is a mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. At present, slitting machine is commonly used to cut aluminum coils. The aluminum coils are transported from the feed end of the slitting machine to the slitting machine. After the aluminum coils are cut by the slitting machine, they are wound and rolled at the discharge end of the slitting machine through the slitting machine expansion shaft. After the rolling work is completed, the slitting machine expansion shaft needs to be loaded and unloaded with steel cylinders in order to carry out the next rolling work. When loading and unloading the steel sleeve of the slitting machine expansion shaft in the existing technology, the expansion shaft is usually lifted by a crane, and then the steel sleeve is put on the expansion shaft or removed from the expansion shaft. This method is not only inefficient in loading and unloading the steel sleeve, but also because the weight of the expansion shaft is heavy, there are safety hazards during the lifting process, and the safety of personnel cannot be guaranteed during the lifting process.
