Description

Technical Field

[0001] The utility model relates to the technical field of flexible printing machines, in particular to a unit type printing machine. Background Art

[0002] Flexographic printing, offset printing, gravure printing and screen printing are the four major printing methods, and flexographic printing has several major characteristics: the ink is mainly pollution-free, fast-drying, does not contain heavy metals, and is mainly environmentally friendly water-based and UV ink; and laser-engraved ceramic anilox rollers are used to transfer ink in a quantitative manner to ensure uniform ink color, consistent tone, and bright and full color of printed products; the printing plate is soft and elastic, and has strong adaptability to various materials; and the plate making speed is fast, the cost is low, and the product quality is stable and reliable.

[0003] At present, when the existing flexible printing machine is in use, after a roll of paper is rolled up after printing, it is necessary to first remove the rolled paper roll on the winding roller and then install a new winding roller on the winding roller for winding. During this period, the flexible printing machine is in a shutdown state, which greatly reduces the printing efficiency of the printing machine. In this regard, we propose a unit printing machine that can greatly reduce the downtime of the printing machine. Utility Model Content
