Problems solved by technology
[0002] The traditional ordinary optical variable ink is completed on the screen printing machine, but the 3D magnetic optical variable ink needs to complete a positioning and fixed magnetism action after printing, and a positioning and fixed magnetism device needs to be installed behind the head of the existing screen printing machine, generally Positioning is carried out by belt transmission and sucker sucking the paper up and down. The positioning and magnetism action is far behind the printing speed, which leads to a very slow printing efficiency of the screen printing machine, and the machine speed only reaches 500-800 sheets. / hour, completely unsuitable for mass production of cigarette packs

The invention provides a metal 3D magnetic optically-variable printing device and method. The device comprises a single gravure machine; an impression cylinder is arranged in the single gravure machine; a feeding cylinder, a gravure plate and a discharging cylinder are sequentially arranged in the circumferential direction of the impression cylinder in a rolling manner; a fixed magnetic cylinder is further arranged on one side of the discharging cylinder in a rolling manner; a first conveying cylinder is arranged on the other side of the fixed magnetic cylinder in a rolling manner and is in transmission linkage with a second conveying cylinder through two chains; a gripper row is fixedly arranged between the two transmission chains; an unloading device is correspondingly arranged at the second conveying cylinder; and a gripper is further arranged on the fixed magnetic cylinder. The problem that existing 3D optically-variable printing equipment is completely unable to meet batch production requirements of cigarette packet products due to the low printing efficiency is solved. The invention belongs to the technical field of optically-variable printing.
Description
technical field [0001] The invention relates to a fast printing device for 3D magnetic optical variable ink, and belongs to the technical field of 3D magnetic optical variable printing. Background technique [0002] The traditional ordinary optical variable ink is completed on the screen printing machine, but the 3D magnetic optical variable ink needs to complete a positioning and fixed magnetism action after printing, and a positioning and fixed magnetism device needs to be installed behind the head of the existing screen printing machine, generally Positioning is carried out by belt transmission and sucker sucking the paper up and down. The positioning and magnetism action is far behind the printing speed, which leads to a very slow printing efficiency of the screen printing machine, and the machine speed only reaches 500-800 sheets. / hour, which is completely inapplicable to the mass production requirements of cigarette packs. Contents of the invention [0003] The pu...
