Automatic overprint and color group tension control printing machine

Title of the Invention: Automatic Overprinting, Tension Control between Color Sets and Printing Machine Patent Application Number: 032l87l0, 6
Abstract: The utility model designs an automatic sleeve and color group tension control printing press. The key is to install a punching mechanism for punching holes on the side of the printing material in front of the first color group. Position the pins that can position the substrate. In the utility model, the plows pass the positioning pins on the punching machine and the paper guide roller to transfer the paper tape in the instantaneous motion state before the coloring group, so that a certain point (arbitrary point) on the paper tape is before each color group is entered. There are horizontal and vertical positions and speeds that are the same as in front of the first color group, so as to eliminate random fluctuations in the sheet feeding and offset of the sheet to achieve a good overprint. The position of the printed sheet positioned by the front side gauge is corrected by the positioning pin on the gripper row to achieve precise stamping and die cutting.
