Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing machines, in particular to a gravure printing plate roller installation structure of a gravure printing machine. Background Art

[0002] Gravure printing machines are mainly used for printing on the outer packaging of products. Gravure printing machines print different patterns on packaging paper through gravure rollers. For example, the mutual squeezing between the movable rod and the slide groove in the adjustable gravure roller (patent number: CN202123019621.9) disclosed in Chinese patent literature drives the mounting block to rotate around the connecting shaft, adjusts the angle of the mounting block, and then changes the height of the rotating shaft and the printing roller, which is convenient for printing products of different thicknesses. When different patterns need to be printed on the outer packaging, the plate roller needs to be quickly replaced to ensure the printing efficiency of the gravure printing machine on the outer packaging.

[0003] Therefore, we propose a gravure printing plate roller installation structure for a gravure printing machine. Utility Model Content
