Cloth feeding method of digital printing and flat screen printing integrated machine

Abstract

The invention discloses a cloth feeding method for a digital and flat screen integrated machine. The method belongs to the technical field of textile printing. The method enables the nozzle group of the digital printing machine to scan the effective width of the inkjet in a single scan, and the scraper of the flat screen printing machine to scrape once. The printing width, the intermittent positioning width of the printing guide belt, and the cloth feeding length of the A-type unwinding device are consistent. The steps of the cloth feeding method of the digital flat screen integrated machine are as follows: the gray cloth enters the first cloth guide roller from the A-type unwinding device, Then go through the second cloth guide roller, the third cloth guide roller and the angle adjustment roller, then to the first wire dividing roller, the edge correction device, then to the second dividing roller, the fourth cloth guiding roller, the fifth cloth guiding roller, And then to the floating press roller; due to the large contact area and long time of the floating press roller, the tension distribution of the gray fabric on the surface of the guide belt is even and the flatness is good, which greatly improves the printing quality.

Description

technical field [0001] The invention designs a cloth feeding method of a textile printing machine, in particular, relates to a cloth feeding method of a digital and flat screen integrated machine. Background technique [0002] The cloth feeding method of the digital and flat-screen integrated machine in the prior art generally adopts the method of flattening the cloth by the splitting roller and adjusting the tension with the angle adjusting roller, and then entering the cloth pressing roller. Enter the printing device of the digital printing machine and the flat screen printing machine for printing. Because the cloth pressing roller presses the grey cloth and makes the grey cloth move forward against the surface of the guide belt, at this time, the surface area of ​​the cloth pressing roller in contact with the grey cloth is very small, and the contact time is short, so that the flatness of the grey cloth cannot be adjusted when the printing guide belt feeds the cloth. It ...

AI Technical Summary

Problems solved by technology

Because the cloth press roller presses the gray cloth, so that the gray cloth advances against the surface of the guide belt, at this time, the surface area of ​​the press roller contacting the gray cloth is very small, and the contact time is short, so that the flatness of the gray cloth cannot be adjusted when the printing guide belt feeds the cloth. Come, cause gray cloth unevenness, wrinkling, local air bubbles and other phenomena, seriously affecting the printing effect of digital and flat screen printing machines

There is another situation: due to the inconsistency of the single-scanning inkjet width of the digital printing machine and the single-scratch printing width of the flat screen printing machine (that is, the size of the flower return), the strokes of each cloth feeding are inconsistent, causing the cloth to stick to the surface of the guide belt. The internal tension of gray fabric fluctuates greatly

When the digital and flat screen all-in-one machine is printed, the pattern on the gray cloth enters the drying device to be heated, which will cause quality defects such as pattern deformation
