[0002] Currently, pad printing, an indirect concave-convex printing technique, has become a major method for printing and decorating various object surfaces. The process is simple: first, the designed pattern is etched onto a printing plate; then, ink is applied to the etched plate; and finally, most of the ink is transferred to the object being printed using a silicone pad.

[0003] A pad printing machine disclosed in CN104401114B includes a frame, on which a ring-shaped feeding mechanism and a printing mechanism are mounted. The ring-shaped feeding mechanism is located below the printing mechanism and includes a conveyor frame with a groove inside. The groove contains a ring track and several moving carriers within the ring track. The ring track is located at the bottom of the groove. The ring-shaped feeding mechanism also includes a drive mechanism that can drive the carriers to move within the ring track. The drive mechanism includes a first drive mechanism and a second drive mechanism. The first drive mechanism is located at the end of the conveyor frame near the printing mechanism, and the second drive mechanism is located within the ring track. The first drive mechanism and the second drive mechanism are connected by transmission through the carriers to realize continuous automated printing of the pad printing machine.

[0004] While existing technologies have achieved continuous automated printing, they cannot cure the printed products and cannot perform two-color printing. Therefore, we propose a two-color pad printing machine. Utility Model Content
