Technical Field

The invention relates to a spreading device, in particular to a spreading yarn and a spreading roller.

Background

In the weaving, printing and dyeing, film manufacturing and printing processes of China at present, cloth grass and other materials need to be unfolded and paved by guide rollers, different materials need to be unfolded by different guide rollers, wherein the materials comprise a left thread spreading roller, a right thread spreading roller, an arc spreading roller and a drum spreading roller, the left thread spreading roller and the right thread spreading roller are the most common, but in the current left thread spreading roller and right thread spreading roller, the cross section shapes of the expanding filaments of the threads are circular or semicircular, in order to achieve the expanding filament spreading purpose, the thread pitches generally exist among the expanding filaments, the thread pitches are not small, if the thread pitches are small, the conduction effect of the guide rollers on the cloth can be influenced, however, if the thread pitches are too large, silk, thin yarn and other soft cloth materials are deformed on the spreading rollers, and the second supporting surface of the circular or semicircular expanding filaments is arc-shaped, the cloth supporting and protecting effects can not be realized, therefore, the spreading roll of circular arc-shaped spreading yarn type such as circular semicircle does not have a protective effect on high fine and soft cloth.

When some fine and soft high-grade special cloth materials are processed, the cloth materials are light, thin, soft and fine, although the cloth spreading capacity of a traditional cloth spreading roller is good, the thread pitch of the width-expanding filaments is large, the cloth materials can sink between the width-expanding filaments, the cloth materials are sunken into the grooves in the middle of two adjacent circles of filaments and deform, the deformation can increase the probability that the cloth materials generate folds and curled edges, the folds and the curled edges are easily generated when the cloth materials are conducted to the ironing roller, the quality of products can be seriously influenced when the folds are generated, the traditional cloth spreading roller is rough in working, the filaments are easily scraped, the cloth materials are damaged, the processing precision of a roller body and the roll filaments cannot meet the cloth spreading requirement of the high-grade cloth materials, the high-grade special cloth materials are high in manufacturing cost, the whole cloth materials can be scrapped when the quality of the cloth materials is unqualified.

Therefore, how to strengthen the protection of the cloth spreading roller on the special cloth and make the special cloth not easy to wrinkle in the flattening process becomes the problem to be solved at present.

Disclosure of Invention
