Problems solved by technology

[0004] Today's environmentally friendly plastic bags need to be manually loaded during screen printing, and manual hand-held scrapers are required to scrape the plastic bags. The printing efficiency is poor and the labor intensity of the workers is high; Due to the light weight of the plastic bag itself, it cannot be printed flat, and there will be wrinkles, which is not conducive to finalizing the shape when printing the pattern, which will lead to errors in the printing of the graphic on the surface of the plastic bag, which will easily cause the pattern to be distorted and deformed, and affect the product quality; therefore, The invention provides a machine and printing method for printing pictures and texts on the appearance of environmentally friendly plastic bags

Abstract

The invention provides an environment-friendly plastic bag outer surface image-text printing machine and a printing method. The environment-friendly plastic bag outer surface image-text printing machine comprises an image printing mechanism, a conveying mechanism, a tensioning mechanism and a bottom plate; solves the problems that when existing environment-friendly plastic bags are subjected to silk-screen printing, continuous manual feeding is needed, workers are required to manually hold scraping plates for scraping printing of the plastic bags, the printing efficiency is poor, and the labor intensity of workers is high; and solves the problems that when image-text printing is carried out on the surface of a plastic bag, the plastic bag is usually light in weight and cannot be flatly printed, wrinkles can occur, shaping is not facilitated when patterns are printed, printing errors are caused at the image-text positions on the surface of the plastic bag, the patterns are prone to being twisted and deformed, and the product quality is affected.

Description

technical field [0001] The invention relates to the technical field of plastic bag processing, in particular to a machine and printing method for printing graphics and text on the exterior of an environmentally friendly plastic bag. Background technique [0002] Environmentally friendly plastic bags include recycled plastic bags and new plastic bags. Plastic bags added with degradable masterbatch during the production of plastic bags are also called degradable plastic bags. The degradable plastic bags can be automatically decomposed after 90 days under certain conditions. Environmentally friendly plastic bags are used to pack various supplies, making it easy to transport and store goods in the process of production and circulation, and are indispensable items in people's daily life. When people use environmentally friendly plastic bags, they usually print pictures and texts on the environmentally friendly plastic bags, so that users can have a better understanding of the pr...
