Gravure printing machine for printing plastic bags with different models

Abstract

The invention discloses a gravure printing machine for printing plastic bags with different models, and relates to the technical field of plastic bag production. The gravure printing machine for printing the plastic bags with different models comprises a bottom mounting plate; a printing machine shell is fixedly mounted at the top of the bottom mounting plate; a groove printing roller is rotationally connected to the interior of the printing machine shell; a guide rubber roller is arranged at the part, located on one side of the groove printing roller, in the printing machine shell; an ink storage box is fixedly mounted at the part, located above the printing machine shell, of the top of the bottom mounting plate; and stopping plates are fixedly mounted on the two corresponding sides of the inner wall of the ink storage box. The gravure printing machine for printing the plastic bags with different models has the beneficial effects that by spraying ink to the groove printing roller in an ink jetting mode and using a spoiler capable of shielding part of the ink jetting groove, the ink jetting range can be controlled, so that the ink staining range of the groove printing roller is controlled, and the plastic bags with different models can be effectively printed; and compared with a printing machine used at present, the printing machine is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of plastic bag production, in particular to a gravure printing machine for printing different types of plastic bags. Background technique [0002] Food packaging bags are a kind of packaging design. In order to keep fresh and store food in daily life, product packaging bags are produced. Food packaging bags refer to film containers that are in direct contact with food and are used to hold and protect food. In the production of food packaging bags, gravure printing is generally used to print trademarks and other patterns on food packaging bags. Gravure printing is to make the whole The surface of the printing plate is covered with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only stays in the mesh of the graphic part, and then under greater pressure, the ink is transferred to the The surface of the substrate to obtain printed matter. Gravure printing be...

AI Technical Summary

Problems solved by technology

The graphic part of the printing plate is concave, and the degree of depression varies with the level of the image. The blank part of the printing plate is raised and on the same plane, but because the printing rollers used for printing are generally the same in length, when When it is necessary to print the same pattern on different types of plastic bags, it is necessary to replace the printing rollers of different lengths, which is inconvenient to use and reduces the processing speed. Therefore, we propose a gravure printing machine for printing different types of plastic bags
