Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, and specifically relates to a feeding and discharging mechanism of a screen printing machine. Background Technique

[0002] When printing round bottles, due to the limitation of the shape of the round bottles themselves, ordinary printing machines can only print flat products, so they cannot adapt to the printing of the round bottle bodies. Therefore, when printing the round bottle bodies, it is necessary to drive the round bottles and the printing squeegee synchronously to achieve the printing effect. Due to the particularity of the scraping printing process, usually the printing squeegee needs to be set horizontally, while the round bottles are usually transported vertically to avoid rolling during transportation. Therefore, when loading for printing, it is necessary to transform the round bottles transported vertically on the conveyor belt into a horizontal state and transport them to the printing equipment for fixing, so as to cooperate with the squeegee for printing. When discharging after printing, it is necessary to transform the round bottles in a horizontal state into a vertical state and then place them on the conveyor belt.

[0003] In the prior art, the application number CN202023272060.9 specifically relates to a feeding and discharging device for bottle body printing, including a mounting frame, a clamping assembly, a rotating assembly and a moving assembly. The rotating assembly is arranged inside the upper end of the mounting frame, the moving assembly is arranged at the lower end of the rotating assembly, and the clamping assembly is arranged at the front end of the moving assembly. The existing device clamps and fixes the bottle body by setting the clamping assembly, and sets the rotating assembly to arbitrarily convert the bottle body between a vertical state and a horizontal state. The overall structure has high automation, high adjustment accuracy, and greatly improves the working efficiency. However, the stability of the fixture in the prior art is insufficient, and the bottle will fall off during the feeding and discharging processes, affecting the production efficiency. In view of this problem, the prior art needs to be improved. Summary of the Utility Model

[0004] In view of the problems existing in the feeding and discharging mechanism of the existing screen printing machine, the present utility model is proposed.
