Description

Technical Field

[0001] The utility model relates to the technical field of bar code printing, in particular to a printing device for highly permeable green bar codes. Background Technique

[0002] A bar code encodes specific numbers, letters, and symbols into a series of black bars and blanks with different widths, and then arranges them according to certain coding rules to form a graphic identifier expressing a group of information, thereby forming a code that can be recognized by a machine.

[0003] The bar code printing device is based on ink, and by heating the ink jet head, a chemical reaction occurs when the heat-sensitive layer of the ink jet head contacts the paper bottom layer. Then, the ink jet head is slid and lifted through a telescopic cylinder and a horizontal lead screw to complete printing, and thus bar codes can be generated.

[0004] During the printing process of the existing printing device for highly permeable green bar codes, since most bar code papers are only tightened by a single cross bar, the bar code paper cannot be tightened flexibly, easily causing the bar code paper to wrinkle. As a result, the bar codes printed by the printing device are not clear, the black bars are not obvious, and the blanks are too wide or too narrow. At the same time, when the existing printing device for highly permeable green bar codes positions the bar code paper, it often only positions through the two side stoppers and cannot be adjusted flexibly according to the thickness and width of the bar code paper, which easily causes the printed bar code paper to break, and thus the continuity of the printed bar codes cannot be guaranteed, reducing the efficiency of batch printing production of bar codes. Content of the Utility Model

At the same time, it also solves the problem that the printed bar code paper is easily broken because it cannot be adjusted flexibly according to the thickness and width of the bar code paper, and thus the continuity of the printed bar codes cannot be guaranteed.
