Printing device and printing method for packaging bag production

Abstract

The invention discloses a printing device for packaging bag production in the technical field of packaging bags. The printing device comprises a workbench. A groove is formed in the outer wall of themiddle of the top of the workbench. Buffer devices are evenly arranged on the outer wall of a conveying belt and are arranged in an annular array manner. A supporting plate is arranged at the end, away from the conveying belt, of each buffer device. Rotating shafts are arranged at the left end and the right end of the outer wall of the side, away from the corresponding buffer device, of each supporting plate. Pressing devices are arranged at the close ends of the rotating shafts of the left set and the right set of each supporting plate. In the device, the pressing devices are moved to the positions above packaging bags, the packaging bags are fixed to the supporting plates, and the situation that the packaging bags move during printing, consequently, printing positions deviate, or part ofpatterns are not printed onto the packaging bags is avoided; and a mold plate is blocked by a sponge layer, the situation that the mold plate is directly inserted into ink, and consequently a large amount of ink is attached to the outer wall of the mold plate is avoided, the situation that the ink drops off from the mold plate to contaminate the workbench and the packaging bags is avoided, and the processing quality of the packaging bags is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a printing device and a printing method for producing packaging bags. Background technique [0002] When the packaging bag is produced, it is necessary to print patterns or text on the surface of the packaging bag. When the template is used to dip the ink, ink will adhere to the surface of the template, and the ink will drip from the template, which will easily pollute the packaging bag and affect the quality of processing. When the bag is printed, it needs to be fixed to prevent the printing position from shifting or part of the pattern not printed due to the movement of the packaging bag, resulting in the failure of the packaging bag processing and wasting resources. Therefore, we propose a printing device for packaging bag production and printing methods. Contents of the invention [0003] The purpose of the present invention is to provide a printing device and print...
