High permeability heat transfer printing machine

Abstract

The invention discloses a high permeability heat transfer printing machine. The printing machine consists of a hot roller, a frame, an operation device, a cloth feeding device, a tensioning system, apaper collecting device, a paper feeding device, a cropping device, a paper pressing roller, a hoist and a motor. The printing machine is ingenious in design and simple and intelligible in structure,and assemblies can be tightly connected to each other but do not influence on each other, so that the easy maintenance of the product during using in the future can be achieved; and the arrangement modes of tension rollers are adjusted, so that the coating surface between the hot roller and a blanket can be increased from traditional 55% to 70-75%, 30-25% space can be left to perform cloth feedingand discharging and paper collecting, and therefore, the normal flattening operation of transfer paper and plush printing carriers can be guaranteed so that the increasing of the coating surface of the blanket can be achieved, the heat transfer length of the plush printing carriers can be increased, the time of printing ink transferring can be prolonged, the transfer rates of printing ink can begreatly increased, correspondingly, the printing ink permeability of printing can be increased as well, printing and dyeing effects and product quality can be enhanced, reject rates can be reduced, and degree of automation can be enhanced.

Description

technical field [0001] The invention relates to the field of printing and dyeing equipment, in particular to a heat transfer printing machine with high permeability. Background technique [0002] Thermal transfer printing is a new printing and dyeing process that has gradually emerged internationally in recent years. First of all, use advanced printing technology to print special printing and dyeing (water-based or oil-based), and print all required patterns on special paper to make transfer printing paper with various patterns. Then, on the transfer printing machine, transfer After the patterned side of the decal paper is closely bonded to the printed fabric, through the action of heat and pressure, the dyes of the decal paper are sublimated and transferred to the printed fabric to form various patterns on the printed fabric. pattern. [0003] At present, the printing and dyeing of high-weight plush cloth in the world still uses traditional magnetic bar dispersion printin...

Problems solved by technology

[0004] In order to solve the above problems, the present invention discloses a high-permeability thermal transfer printing machine. The surface layer cannot reach the bottom of the fabric, and the dye penetration is not enough, not to mention printing and dyeing ultra-high weight Raschel cloud blankets, whose long fibers cannot penetrate the roots efficiently with existing ordinary heat transfer printing machines. Poor printing and dyeing results lead to low product quality and waste of resources. After research, the main reason for the inability to reach the penetration rate is that the wrapping angle of the blanket attached to the hot roller is too small, which causes the plush printing carrier to be transferred by heat. The length is not enough. The covering surface of the blanket of ordinary thermal transfer printing machine is about 55%. To improve the printing and dyeing efficiency, it is necessary to increase the covering surface. Under the premise that the transfer paper and plush printing carrier can run normally and smoothly The covering surface should be maximized, that is, the wrapping angle between the hot roller and the blanket of the thermal transfer printing machine should be maximized, and the index should be between 70% and 75% as the standard, leaving 30% to 25% The main measure is to increase the covering surface of the blanket by adjusting the arrangement of the tension rollers inside the thermal transfer printing machine.
