Technical Field

[0001] The utility model relates to the technical field of label printing, in particular to a label printing paper feeding mechanism. Background Art

[0002] The wide application of labels and the continuous development of label varieties have naturally promoted the development of label printing technology. Label printing covers all printing methods such as flat, convex, concave, and mesh, and the application situation in different countries is different. However, from the development trend of global labels in recent years, it can be seen that flexographic printing, narrow web rotary printing, and digital printing have become new highlights of label printing in Europe and the United States, and are also the development trend of label printing.

[0003] After searching, the China Patent Network disclosed a label printing paper feeding mechanism with the publication number CN209853387U. Although it can increase the friction between the roller and the label paper, making the paper feeding mechanism less likely to slide and improving the paper feeding efficiency, it can also scrape off the debris on the label paper and also flatten the label paper to prevent the label paper from being indented and affecting the quality of the label, but the roller and pressure roller in the patent are relatively cumbersome to adjust, inconvenient to use, and require a large number of parts to complete, with a complex structure and high production and use costs.

[0004] Therefore, a label printing paper feeding mechanism is proposed. Utility Model Content

[0005] The utility model aims to provide a label printing paper feeding mechanism.
