A set of bearings is installed at each end of the shaft for the cylinder drum to rotate flexibly. In order to ensure that the cylinder shaft and the flange are tightly combined, a cylinder flange cone sleeve is driven in from the outside to the inside between the cylinder shaft and the flange. The inner ring of the cylinder flange is a cylindrical inner hole, and the outer ring of the cylinder flange is a conical flange cone sleeve. During production, when the cylinder shaft is worn and replaced, the cylinder flange cone sleeve must also be disassembled and repaired. During maintenance, only a long shaft with a flat mouth at one end can be inserted into the cylinder drum from the other end of the cylinder, aligned with the flange cone sleeve, and a hammer is used to hit the tail end of the flat mouth long shaft hard so that the head end of the flat mouth long shaft impacts the small head end of the flange cone sleeve and withdraws from the flange cone sleeve.
