Proportioning device and proportioning method of water-based flexographic printing ink

Abstract

The invention belongs to the technical field of printing ink production, relates to a proportioning device and a proportioning method of water-based flexographic printing ink, and aims to solve the problem that the water-based flexographic printing ink is easily and firmly attached to dead angles due to heating or stirring in a traditional proportioning process. The proportioning device arranged in the process comprises a preparation box with an upward-facing opening, the preparation box is of a barrel-shaped structure, a hoop is fixed to the position, close to the top end, of the circumferential outer wall of the preparation box, a supporting block is fixed to the outer wall of the hoop, two parallel channel steel beams with opposite openings are fixed to the top end of the supporting block, a fixed clamping frame is fixed to the ends, away from the supporting block, of the two channel steel beams. According to the proportioning device and proportioning method of the invention, when a stirring action is finished, an internal combined stirring rod does not need to be pulled out, only a driving motor needs to be started to drive a mud scraping plate box tightly attached to the inner wall of the preparation box to rotate, and meanwhile, a hanging pipe is slowly pressed downwards, so that a toner attached to the inner wall of the preparation box can be quickly and timely cleaned up.

Description

technical field [0001] The invention relates to the field of production equipment and production technology of printing ink, in particular to a mixing device and a mixing method of water-based flexographic printing ink capable of cleaning inner barrel parts in time. Background technique [0002] The water-based flexo printing ink in the printing ink is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. The special ink used in the flexographic printing machine is water-based ink, which has the advantage of no pollution to the environment. No impact on human health, non-flammable, good safety, stable ink performance, bright colors, no corrosion of plates, simple operation, cheap price, good post-press adhesion, strong water resistance, fast drying, printing speed can reach per minute 150~200㎡; precisely because of the above characteristics, flexo printing water-based ink is especially suitable for the printing and use ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defect that the traditional water-based flexo printing ink is easily attached to the dead corner due to heating or stirring in the mixing process, the present invention provides a water-based flexo printing ink mixing device and a mixing ratio that can clean the inner barrel parts in time method
