A high-precision printing device for express delivery bags

Abstract

This utility model discloses a high-precision printing device for express delivery bags, relating to the technical field of express delivery bag production equipment. The utility model includes a frame, an ink supply mechanism, and an adjustment mechanism. Four sets of first and second rotating sleeves are connected to both sides of the frame via bearings. Four motors are installed on one side of the frame, and the output ends of the four motors are respectively connected to the first rotating sleeves. A first connecting shaft and a second connecting shaft are respectively connected inside the first and second rotating sleeves, and a fixed shaft connects the first and second connecting shafts. This utility model, through a "cross-shaped first and second connecting shaft + first and second sliding groove" mating structure, combined with a detachable fixed shaft and roller body, eliminates the need to disassemble the rotating sleeves or clean the ink path during printouts. Simply loosening the fastening nut and pushing the fixed shaft away from the second rotating sleeve allows for roller replacement, significantly shortening roller replacement time. Simultaneously, the roller can be replaced independently, reducing spare parts inventory and lowering equipment procurement and maintenance costs.
