Environment-friendly packaging bag printing equipment and printing process thereof

Abstract

The invention discloses environment-friendly packaging bag printing equipment and a printing process thereof, and relates to the technical field of printing equipment. The environment-friendly packaging bag printing equipment comprises a shell; a winding mechanism and an unwinding mechanism are fixedly arranged between the inner surfaces of the shells correspondingly; a packaging bag to be processed is wound on the circumferential side faces of the winding mechanism and the unwinding mechanism; the top surface of the shell is fixedly provided with a negative pressure dust collector, a first ink supply assembly and two hot air supply mechanisms respectively; one ends of air inlets of the two hot air supply mechanisms both communicate with the shell; filter assemblies are fixedly installed at the joints of the two hot air supply mechanisms and the shell; and a pre-cleaning mechanism, a lower printing mechanism and an upper printing mechanism are fixedly arranged in the shell from front to back respectively. Through the design of the equipment structure and the printing process, the double-sided printing work of the packaging bag can be completed by the device in the form of an automatic production line, and through the addition of the pre-cleaning mechanism, the surface of the paper bag can be pre-cleaned during printing, so that the printing effect of the device is effectively guaranteed and improved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to an environment-friendly packaging bag printing equipment and a printing process thereof. Background technique [0002] Packaging bag refers to the bag used to pack various supplies, so that the goods are conveniently transported and stored during the production and circulation process; they are widely used in daily life and industrial production; actual figures show that 80% of the plastic bags after use are eventually Like ordinary garbage, it is transported to the landfill area for disposal, and only 7% of the plastic is recycled. [0003] When printing, the packaging bags are generally connected together and printed by rolling; when the general packaging bags are printed, they may be in a relatively open environment, which is easy to attach dust, and at the same time, the odor generated by the volatilization of the ink is easy to diffuse into the outside...

Problems solved by technology

[0004] The purpose of the present invention is to provide an environment-friendly packaging bag printing equipment and its printing process. Through the design of the upper printing mechanism, the lower printing mechanism, and the pre-clearing structure, it solves the problem that the existing packaging bag printing equipment cannot pre-clear the paper bag. Problems with poor drying and deinking
