Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and particularly to a printing equipment for realizing automatic label printing. Background Art

[0002] The extensive 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 screen printing, and the application situations in different countries are not the same. However, from the development trend of global labels in recent years, flexographic printing, narrow-web rotary printing, and digital printing have become new highlights in label printing in European and American countries, and are also the development trends of label printing.

[0003] Label printing requires the use of label printing machines, which are also called trademark printing machines or self-adhesive printing machines, and are equipment for printing labels and trademarks. Label printing and label equipment manufacturing absorb the advantages of various printing technologies and gradually form a relatively independent system to adapt to the diversified development of the label application field. It can very flexibly select systems with different formats, different numbers of color groups, and different configurations, and can meet the needs of customers at different levels from high-end to low-end. In the near future, it can reach the speed of traditional printing machines while the cost increase is not significant. And its operating cost is low. Different from other digital printing machines that usually operate independently, the inkjet printing module can also be installed on the traditional printing production line and combined with the traditional printing production line for combined printing, so that the traditional printing technology and digital printing technology can complement each other's advantages and form a perfect combination.

[0004] However, for the drum bearings on existing trademark printing machines, due to natural wear during long-term high-speed operation or unqualified bearing quality, they are prone to wear. When the drum bearings are damaged, the drum will have jitter and abnormal noise, and the temperature of the drum shaft head will be too high. The damage of the drum bearings will cause regular jitter during the operation of the machine, jittering once or several times per revolution. When jittering, the force on the printing plate increases, resulting in wear of the printing plate, and one or several ink bars will appear axially on the printing plate, reducing the printing resistance of the printing plate. In the prior art, this problem can only be discovered through regular manual maintenance or when defective products appear in the printed matter, which easily leads to an increase in the defective product rate, an increase in the number of finished products, and affects the processing efficiency. Summary of the Invention

[0018] Beneficial effects

[0019] The present invention has the following beneficial effects:

[0020] (1) For the printing device for realizing automatic label printing, by sleeving the printed matter to be processed on the feeding roller, then installing the feeding roller between two connecting shafts, driving the roller bearing to rotate through the driving motor, thereby driving the feeding roller to rotate, so that the printed matter to be processed is conveyed below the printing unit.

[0022] (3) When the drum bearing of the printing device for realizing automatic printing of labels becomes loose, the drum bearing vibrates in the movable groove, causing the vibrating tuning fork in the sensing cavity to vibrate synchronously.
