Printing roller mechanism for digital printing and printing method thereof

Abstract

The present invention relates to the technical field of printing roller mechanism, especially a printing roller mechanism for digital printing and its printing method. The following scheme is proposed, which includes a printing machine body, a printing mechanism is arranged on the printing machine body, and the printing mechanism includes a workbench. Two support plates are fixedly connected to the workbench, and the two support plates are provided with inclined upward guide grooves, and the first connecting shaft is arranged between the two guide grooves, and the two ends of the first connecting shaft are separated by sliders. Slidingly connected with two guide grooves, a rubber roller is arranged on the first connecting shaft, a first connecting rod is arranged above the rubber roller, a movable repairing mechanism is arranged on the first connecting rod, and the repairing mechanism cooperates with the rubber roller, One side of the rubber roller is provided with a circulating cleaning device that matches the repairing mechanism. One end of the first rotating column extends to the other side of the support plate and is connected to the second connecting rod in transmission. The second connecting rod is connected to the third connecting rod in rotation. rod, and the third connecting rod is rotatably connected with the slide block. The invention achieves the purpose of cleaning and repairing the rubber roller.

AI Technical Summary

Problems solved by technology

[0003] During the working process, the printing rubber rollers usually appear, wear, and have holes, and during long-term use, some residual impurities accumulate on the rubber surface of the rubber rollers, and some of the residues can be cleaned with water or solvents. However, there are still a small amount of impurities remaining at the bottom of the micropores on the rubber surface. These residues accumulate in the pores for a long time. Under the action of printing pressure and heat, the surface of the rubber roller will eventually lose its microporosity and be glazed. treatment, the glazing layer will become thicker and thicker, which will eventually cause great harm to the printing. Since the rubber roller is difficult to replace and disassemble, if the new roller is replaced, the cost will be too high and the production progress will be affected. Therefore, the present invention proposes A printing roller mechanism for digital printing and printing method thereof
