Roller printing machine

Abstract

The invention discloses a roller printing machine. The roller printing machine comprises a rack, wherein a heating plate is mounted at the top end of the rack; a heating wire is mounted inside the heating plate; a printing roller is mounted below the heating plate; a scraper roller and a spraying roller are mounted on one side of the printing roller; a dye collecting box and a water pump which are mounted on the rack are arranged below the printing roller; and the dye collecting box is connected with the inlet of the water pump through a feeding pipe. The roller printing machine has the advantages that by adoption of a dye spraying plate arranged on the outer surface of the printing roller, the surface of the printing roller can be uniformly and completely sprayed with a dye; meanwhile, the arranged dye collecting box can be matched with the water pump to recover the residual dye into the spraying roller, so that not only can resources be saved, but also the production cost can be reduced; and as the heating wire is arranged in the heating plate which is easy in heat conduction, heat can be generated to evaporate water in cloth which is being printed, and the impact of water contained in the dye on the printing process can be avoided.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a roller printing machine. Background technique [0002] The process of printing on fabrics with copper cylinders engraved with concave patterns is also called copper roller printing. The engraved roller is called the fountain for short. When printing, first stain the surface of the fountain tube with color paste, and then use a sharp and flat scraper to scrape off the color paste on the surface of the unengraved part of the fountain tube, so that the color paste remains in the concave pattern. When the flower tube is embossed on the fabric, the color paste is transferred to the fabric to print the pattern. However, the existing roller printing machines mostly use a single nozzle nozzle to spray the printing cylinder, which easily leads to incomplete spraying, and the redundant dyes are often discarded and not reused. This not only wastes resources, but also increases...

AI Technical Summary

Problems solved by technology

However, the existing roller printing machines mostly use a single nozzle nozzle to spray the printing cylinder, which easily leads to incomplete spraying, and the redundant dyes are often discarded and not reused. This not only wastes resources, but also increases production costs. And for the printed fabric because the dye contains moisture, if it is not processed in time, it will cause printing deformation, affecting the quality and aesthetics
