An environmentally friendly packaging bag printing equipment and its printing process

Abstract

The invention discloses an environment-friendly packaging bag printing equipment and a printing process thereof, and relates to the technical field of printing equipment. The invention comprises a casing; a winding mechanism and an unwinding mechanism are respectively fixedly installed between the inner surfaces of the casing; a packaging bag to be processed is wound around the winding mechanism and the unwinding mechanism; the top surface of the casing is respectively fixed and installed with negative pressure suction Dust machine, the first ink supply assembly and two hot air supply mechanisms; one end of the air inlet of the two hot air supply mechanisms is connected with the housing; the connection between the two hot air supply mechanisms and the housing is fixedly installed with a filter assembly; the inside of the housing is from front to Afterwards, the pre-cleaning mechanism, the lower printing mechanism and the upper printing mechanism are fixedly installed respectively. The present invention enables the device to complete the double-sided printing of the packaging bag in the form of an automated assembly line through the design of the equipment structure and printing process. Through the addition of the pre-cleaning mechanism, it can also pre-clean the surface of the paper bag during printing, and then effectively guarantee and improve the printing effect of the device.

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
