Flat-screen developing machine

Abstract

The invention discloses a flat-screen developing machine which comprises a screen frame seat arranged on a machine frame, a lighting device arranged behind the screen frame seat, and a developing vehicle sleeved on the screen frame seat and driven by a power device to go up and down repeatedly; the developing vehicle comprises a cylindrical vehicle body arranged transversely; a spray device is arranged in the cylindrical vehicle body and comprises a group of spray pipes or a plurality of groups of spray pipes arranged up and down; each group of spray pipes comprises a spray pipe positioned behind the screen frame seat and another spray pipe correspondingly arranged in front of the screen frame seat; a plurality of spray nozzles which are the same are arranged on two spray pipes in the same group; and the spray nozzles of different groups of spray pipes are different. When the flat-screen developing machine is used for develop a screen printing plate automatically, the influences of human factors can be eliminated, the aperture ratio of screen patterns is improved, the developing effect is uniform, and the developing speed is improved.

Description

technical field [0001] The invention relates to the technical field of flat screen printing, in particular to a flat screen developing machine. Background technique [0002] Flat screen printing is suitable for printing on woven and knitted fabrics such as silk, cotton, chemical fiber, etc., and is more suitable for printing of small batches of high-grade fabrics with many varieties due to its advantages of convenient plate making, large flower length, multiple colors, and ability to print fine patterns. . [0003] Before flat screen printing, it is necessary to make a printing plate first. The plate making is to accurately separate the colors of the pattern to be printed, and find out the cycle unit, and make the same color on each pattern according to the size of the integer multiple of the cycle unit. On the sieve, hollow out the patterned parts and block the meshes of the non-patterned parts to prevent the color paste from being transferred to the fabric during printing...

AI Technical Summary

Problems solved by technology

[0005] At present, the flat screen development operation in the domestic textile printing and dyeing industry is still in the stage of manually developing the screen surface with a spray gun. The defects of manual development are: due to the influence of human factors, the pattern opening rate of the developed screen surface is low. It is not uniform enough, it is difficult to guarantee the delicate printing quality of the fabric; and the developing speed is slow, the production efficiency is low, and it is labor-intensive for the operator
