Ink-jet printing machine and printing process using same

Abstract

The invention relates to an ink-jet printing machine, which comprises a rack, a conveying device arranged on the rack and used for driving cloth to move, a tensioning device arranged on the rack and used for tensioning the cloth, and a spray head located above the cloth and moving in a reciprocating mode in the weft direction of the cloth so as to conduct jet printing on the cloth; a dust collection block is arranged on the side, moving towards a to-be-printed area of the cloth, of the spray head; the dust collection block is fixedly connected with a dust collection pipe; the end, away from the dust collection block, of the dust collection pipe is communicated with a negative pressure fan arranged on the rack; a dust collection opening is formed on the surface, facing the cloth, of the dust collection block; the dust collection pipe is communicated with the dust collection opening; and the dust collection block is provided with a dust collection opening closing device capable of closing the dust collection opening. When the spray head moves to conduct jet printing on the cloth, the dust collection block moves along with the spray head, and dust collection treatment is conducted on the cloth before jet printing of the spray head, so that the surface of the cloth is clean before jet printing, and the effect of improving the printing quality of the cloth is facilitated.

Description

technical field [0001] The invention relates to the technical field of cloth printing, in particular to an inkjet printing machine and a printing process using the equipment. Background technique [0002] Some exquisite patterns are often printed on the surface of the fabric to enhance consumers' desire to buy. Traditional fabric printing needs to go through the complex process of plate making, and the pollution is relatively large, while inkjet printing is directly printed on the fabric. The overall process is simplified and pollution is reduced. [0003] Existing inkjet printing machines generally use the nozzle to reciprocate along the weft direction of the cloth to continuously print the ink in the ink cartridge on the surface of the cloth. [0004] In view of the above-mentioned related technologies, the inventor believes that before printing, fine dust is likely to exist on the surface of the cloth, and the printing chroma on the surface of the cloth and the fastness ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that before printing, fine dust is likely to exist on the surface of the cloth, and the printing chroma on the surface of the cloth and the fastness in the later stage of printing may all decrease, and there is a defect that the printing quality of the cloth is reduced
