Two mounting holes are arranged side-by-side on each mounting plate 1', and bearing seats 2' are installed inside these holes. The rubber roller 3' and the anilox roller 4' are respectively installed within the two bearing seats 2'. During the printing process, the rubber roller 3' and the anilox roller 4' inevitably experience malfunctions. In such cases, it is necessary to remove either the rubber roller 3' or the anilox roller 4'. Since the mounting plate 1' is a single piece of material, whenever any roller malfunctions and needs to be disassembled, both mounting plates 1' on both sides must be removed from the frame. Then, both rollers and the mounting plates 1' on both sides must be removed together before the rubber roller 3' or the anilox roller 4 can be disassembled for maintenance or replacement. This causes significant inconvenience to the disassembly of each roller. Utility Model Content
