Dominant cloth roll group in fixation steaming box

Abstract

The invention discloses a main cloth-guiding roller unit which is used for a color-fixation steaming box and can reduce the occupied area, conserve steam, bring convenience for cleaning and guarantee dyeing quality. The main cloth-guiding roller is characterized in that the main cloth-guiding roller is composed of four rows of main cloth-guiding rollers, and each row of main cloth-guiding rollers are vertically arranged in the box body of the color-fixation steaming box and are composed of a plurality of cloth-guiding rollers, and each neighboring two rows of main cloth-guiding rollers among the four rows of main cloth-guiding rollers form one group of matched main cloth-guiding rollers for the operation to fabrics.

Description

technical field [0001] The invention relates to a color-fixing steam box in the field of printing and dyeing machinery, in particular to an arrangement mode of a main cloth roller group in the color-fixing steam box. Background technique [0002] In the printing and dyeing machinery industry, the color-fixing steam box is mainly used for open-width continuous dyeing of fabrics and then open-width steaming and color fixing. It is also usually called a reduction steam box in the industry. Its structure can be seen in Figure 2; To ensure that the fabric runs according to the process requirements in the color-fixing steam box, a cloth guide roller is arranged in the box body 1 of the color-fixation steam box, and the cloth guide roller can usually be divided into a main cloth guide roller group and an auxiliary cloth guide roller group. The arrangement of the traditional leading cloth roller group is as follows: the leading cloth roller group is composed of upper and lower rows ...

AI Technical Summary

Problems solved by technology

The disadvantages of the leading cloth roller group in the above arrangement are: 1. Since the upper and lower rows of leading cloth rollers 2 and 3 are all arranged in the horizontal direction, the overall arrangement length of the leading cloth roller group is relatively long, resulting in The length is also longer, which increases its footprint, and also increases the amount of consumables for the box and the consumption of steam; 2. Due to the technological requirements, the distance between the two rows of leading cloth rollers 2 and 3 should generally not exceed one meters, and deduct the diameter of the leading cloth roller itself, so the actual clear space height is generally less than 850mm, making workers have to bow their heads when cleaning the cloth guide rollers, which is very tiring and troublesome, and it is difficult to clean thoroughly. It will cause quality problems such as staining and wrinkling; 3. When workers are doing cleaning work, they often bear weight on the lower row of leading cloth rollers. Long-term, multiple, and repeated cleaning will cause the lower row of leading cloth rollers to bend, affecting the leading cloth rollers. The running accuracy of the roller group ultimately affects the quality of the produced product, so after a period of use, the lower row of leading cloth rollers must be replaced, which increases production costs; In the process of circuitous operation, when saturated steaming is performed, a certain amount of condensed water will be generated on the fabric, and the condensed water will flow down along the fabric in a linear and irregular manner under the action of gravity, resulting in uneven dyeing of the fabric surface.
