Duplex printing and automatic single-face film covering printing and dyeing device

Abstract

A duplex printing and automatic single-face film covering printing and dyeing device comprises a rack, a transfer film conveying part, a transfer back plate conveying part, a fabric conveying part, afabric rolling part, a transfer back plate rolling part, a transfer back plate separation part and an embossing part. The mechanical structure of the printing and dyeing device is simple, and during transfer printing, machine operation is high in stability. According to a transfer printing process, a roller transfer method, namely cold transfer printing, at the natural environment temperature is adopted, and the situation that transfer patterns are dim during traditional transfer printing can be prevented. A pattern is printed and dyed to a fabric through a transfer film, a printing and dyeingback plate assists in the printing and dyeing processes, after embossing is completed, the back plate is stripped off, cyclic utilization is achieved, and the transfer film is not stripped off and isrolled and stored along with the fabric; due to the existence of the transfer film, the transfer film can protect the printed and dyed fabric; and the transfer film is located between the two layersof fabrics all the time when the transfer film is rolled along with the fabrics, the situation that the printed and dyed fabrics make direct contact is avoided, cross color and mutual staining of dyesare avoided, and the duplex printing and automatic single-face film covering printing and dyeing device has the beneficial effect of being high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a novel double-sided printing single-sided automatic film-coating printing and dyeing device. Background technique [0002] Transfer printing was launched by Sublistatic in the world in 1968; because the product and production process meet the requirements of energy saving and environmental protection, and the operation is simple, it soon set off a wave in the market. A revolution in printing. But this transfer printing is limited to synthetic fiber fabrics such as polyester fiber, and is applied to natural fiber fabrics such as cotton, wool and silk, still has many shortcomings and problems. In recent years, the cotton transfer printing technology has been successful. The cotton transfer printing is to print the dyes originally printed on the cotton cloth on the transfer paper, and then transfer the dyes on the cotton cloth by mechanical or chemical methods....

AI Technical Summary

Problems solved by technology

Since this is a roller-type embossing device, its working principle is different from that of transfer printing, and the structure of the roller is not suitable for transfer printing, and the process requirements for roller meshing are not as high as transfer printing, and the above problems cannot be solved.

In addition, the existing transfer printing device or transfer method needs to remove the transfer paper during the process, and in order to protect the printed surface of the fabric, it is best to cover a layer of protective film on the surface of the printed fabric, which is low in production efficiency, and Due to the use of the transfer paper collecting device in the printing machine, it also causes the complexity of the machine structure to a certain extent, which is not conducive to saving energy
