Double-sided direct dyeing printing machine

Abstract

The invention provides a double-faced direct dyeing and printing machine. The double-faced direct dyeing and printing machine comprises a fluff removal, adsorption and collection assembly used for removing fluffs on the surface of a cloth, a liquid immersion and extrusion assembly used for immersing the cloth to improve colouring firmness, a temperature and humidity adjustment assembly used for adjusting a temperature and a humidity of the cloth, a first-stage printing assembly used for carrying out primary printing on the cloth, a drying assembly used for carrying out drying treatment on the cloth subjected to the first-stage printing, and a second-stage printing assembly used for carrying out front-surface printing on the dried cloth, wherein the assemblies are connected through a conveying roll group, and the cloth subjected to the first-stage printing is automatically turned over through the conveying roll group, and conveyed into the second-stage printing assembly. The double-faced direct dyeing and printing machine provided by the invention has the following beneficial effects: the two stages of printing assemblies are arranged for continuously printing the front surface and the back surface of the cloth, without the need of interrupting the turnover operation, so that the processing speed is fast and the efficiency is high; the fluff removal, adsorption and collection assembly is arranged for removing impurities such as fluffs, so that the printing quality is improved; and the liquid immersion and extrusion assembly is arranged for treating the surface of the cloth through a cleaning liquid, so that the colouring firmness is effectively improved.

Description

technical field [0001] The invention relates to the field of dyeing and printing equipment manufacturing, in particular to a double-sided direct dyeing and printing machine. Background technique [0002] Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method. It imprints the ink contained in the gravure pits directly onto the substrate. The shades of the printed picture are determined by the size and depth of the pits. If the pits are deep , it contains more ink, and the ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing Just thinner. The printing plate of gravure printing is composed of pits corresponding to the original graphics and the surface of the printing plate. When printing, the ink is filled into the pits, and the ink on the surface of the prin...

AI Technical Summary

Problems solved by technology

[0004] The existing fabric printing machines have the following deficiencies: 1. The front and back sides cannot be directly dyed and printed continuously, and there is an intermittent turning operation between the front and back printing processes, resulting in slow processing speed and low efficiency; 2. The surface of the fabric is prone to electrostatic adsorption fluff Impurities such as thread ends affect the printing effect; 3. Due to material and other reasons, the printing process and coloring of the fabric are not firm; 4. The ink is easy to diffuse and penetrate, causing the pattern to blur, and the printing quality is difficult to guarantee; 5. Due to the long conveying mechanism, the fabric is easy to shift resulting in printing misalignment
