Description

PI liquid collecting device of small-sized printing machine

Technical Field

The present utility model relates to the field of flexographic printing plate manufacturing. More particularly, the present utility model relates to a PI liquid collection device for a compact printer.

Background

The alignment film printing refers to printing a glass substrate by using a PI printer and a method of transferring ink (PI liquid) to a flexible photosensitive resin plate through an anilox roller, and is one of relief printing processes, and is called flexography for short. The printing part of the alignment film printing plate is convex, the anilox roller uniformly coats the ink (PI liquid) layer with a certain thickness on the part of the printing plate to be printed, and then the ink (PI liquid) layer of the part to be printed is transferred to the surface of a printing stock under the action of the pressure of the impression cylinder to form an alignment film. The patent is directed to a G2.5-generation compact printer with a waste collection tank; a waste liquid recovery pipe; a waste liquid collecting barrel. Before and after printing, the printer needs to clean the anilox roller by using NMP solvent, then clean the NMP solvent remained on the anilox roller by dipping alcohol with dust-free cloth, and after cleaning, the printer can start to drop PI liquid for printing. The excessive NMP solvent and PI liquid dripped before and after the operation and during the operation are collected in a waste liquid collecting tank, and finally flow into the same waste liquid collecting tank together, and the PI liquid mixed with the NMP solvent has extremely poor printing effect after repeated use, so that the waste liquid can be scrapped together; the PI liquid has extremely high cost, and the direct scrapping can cause serious cost loss; and a large amount of scrapped chemical solvents are easy to pollute the environment.
