Roller printing machine

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a printing machine, and more particularly to a cylinder printing machine capable of performing a single printing operation on a work article or a plurality of overlapping printings.

Generally, the screen printing machine designs a single fixture group on the printing cylinder, and the fixture group will clamp the workpiece during the feeding position, and the subsequent printing cylinder will continue to rotate to drive the workpiece to the position of the screen carrier. The screen carrier cooperates with the printing drum to move horizontally synchronously, so that the working piece between the printing cylinder and the screen carrier completes printing, and then the clamping group will release the working piece when the working piece moves to the returning position. , so that the work piece leaves the printing cylinder to complete the screen printing process, after which the printing cylinder will continue to rotate to the feeding position again, and form an open state to prepare to clamp the next working piece, but the screen of the single set of clamping sets The printing press can only perform one printing job alone when the printing cylinder is rotated 360 degrees, which will result in low efficiency of the entire screen printing.

Therefore, in order to improve the performance of the conventional screen printing machine, a screen printing machine with multiple fixture sets is available, as shown in FIG. 1, such a screen printing machine 1, including: a printing cylinder 10, a screen carrier 11.
