Sprayer cleaning mechanism and using method thereof

Abstract

The invention relates to a sprayer cleaning mechanism and a using method thereof. The sprayer cleaning mechanism comprises ink absorption pad bodies, an ink absorption pad supporting table and a lifting mechanism, wherein the lifting mechanism comprises a driving motor and a two-way screw rod connected with the driving motor. The two ends of the two-way screw rod are in threaded connection with screw fixing plates respectively, and the screw fixing plates abut against an ink absorption pad bottom plate. The screw fixing plates are connected with shear type supporting frames, the bottoms of theshear type supporting frames are connected with the two screw fixing plates, and the tops of the shear type supporting frames are connected with the ink absorption pad supporting table. The ink absorption pad bodies move along with the ink absorption pad supporting table at the same time, and the bottoms of the ink absorption pad bodies are communicated with cleaning pipes respectively. Each cleaning pipe comprises a water washing pipe body used for inflow and outflow of water and an air suction pipe body for air extraction, wherein the ends, away from the ink absorption pad bodies, of the water washing pipe bodies are connected with a water pump, and the ends, away from the ink absorption pad bodies, of the air suction pipe bodies are connected with an air pump. The sprayer cleaning mechanism has the advantage of more sufficiently cleaning sprayers.

Description

technical field [0001] The invention relates to the technical field of printing machine cleaning, in particular to a nozzle cleaning mechanism. Background technique [0002] The photo machine sprays inks of different color combinations to the inkjet printing medium through the nozzle to form the required pattern on the inkjet printing medium. The spray head is installed on the spray truck, which is driven by the spray truck to move laterally to spray in the width direction of the inkjet medium. [0003] After the existing nozzles spray ink, the ink will remain on the lower surface of the nozzles, and it will dry out easily after a period of time, and block the nozzle holes of the nozzles, making it difficult for the subsequent ink to be ejected from the nozzles to print on the printing medium; or The ink will flush out the dried ink block and print on the printing medium, affecting its printing effect. Therefore, after a period of shutdown, when reprinting is required, the...

Problems solved by technology

[0005] However, in the above-mentioned prior art solutions, the cleaning of the nozzles is mainly done by vacuuming the excess ink in the nozzles by the air pump, and after the ink condenses into blocks, the effect of cleaning the ink blocks is greatly reduced.
