Flexographic printing machine

Abstract

The invention relates to the technical field of printing machines, and discloses a flexographic printing machine. The flexographic printing machine comprises an ink dipping roller and an ink storage box, wherein arc edges are arranged on the two sides of the ink storage box; a flow guide stage is arranged at the bottom of the ink storage box; cyclone air nozzles are arranged on the two sides, located at the flow guide stage, of the bottom of the ink storage box; an annular motion track is arranged between the arc edges and the flow guide stage; a cutoff mesh is arranged on the inner side of the ink storage box; and a magnet is connected to the bottom of the cutoff mesh. According to the flexographic printing machine, through the arrangement of the arc edges, the flow guide stage and the cyclone air nozzles, when the two cyclone air nozzles work, the pressure of the air can push the ink to flow inside the ink storage box counterclockwise, so that the density of the upper-layer ink and the density of the lower-layer ink can be mixed, and the ink is in a uniform state; and furthermore, through the arrangement of the arc edges and the flow guide stage, the motion track of the ink can be the annular motion track, the resistance is small, the motion potential energy is large, the stirring effect is better, and the ink uniformity is better.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a flexographic letterpress printing machine. Background technique [0002] The flexographic letterpress printing machine is a kind of printing machine. Its function is to evenly dip the ink on the protruding pattern on the printing plate roller, and print the pattern on the woven bag, plastic bag and other materials to complete the printing. [0003] see Figure 1-2 , the existing inking module of the flexographic letterpress printing machine comprises a printing plate roll 1, a squeeze roll 2 is installed on the left side of the printing plate roll 1, and a printed product 3 is pressed between the printing plate roll 1 and the squeeze roll 2, and the printing plate roll The right side of 1 is equipped with inking roller 4, and the right side of inking roller 4 is installed with ink roller 5, and ink storage box 6 is installed directly below ink roller 5, and the inside...

AI Technical Summary

Problems solved by technology

[0004] The problem still existing in the existing inking module is: the ink 7 is left to stand for a period of time, or after the letterpress printing machine is shut down for a period of time, precipitation will occur. The upper layer of the ink 7 is thinner and has a lower viscosity; the lower layer of the ink 7 It is thicker and has a higher viscosity. If the ink 7 is directly poured into the ink storage box 6 or turned on directly in this case, the printed pattern will be uneven. The pattern ink 7 of a part of the printed product 3 is thin and the pattern is not clear; The pattern ink 7 of the printed product 3 is thicker, and the pattern color is darker
