Description

Technical Field

[0001] The utility model relates to the technical field of weft straightening of sofa fabrics, in particular to a weft straightening device for dyeing, shaping and straightening of sofa fabrics. Background Art

[0002] The weft straightening process of sofa fabric is a preparatory process before dyeing and finalizing. It mainly checks whether the fabric surface is skewed or bent. When the weft skew or weft bend exceeds the allowable range, it must be adjusted by the weft straightening device. The existing weft straightening device generally uses a photoelectric weft straightening machine, which uses analog detection technology to check and analyze the weft skew and weft arc of the woven fabric and perform correction processing, which is not affected by the fabric color or printing pattern.

[0003] When the existing photoelectric weft straightening machine straightens the sofa fabric, there may be dust and other impurities in the air. The dust and other impurities will move to the position above the photoelectric probe, causing the photoelectric probe to be blocked by the dust and other impurities, and unable to effectively judge the weft situation, resulting in errors in the weft straightening, affecting the recognition accuracy, and reducing the dyeing and finishing quality. The subsequent rework will increase the cost of use. Utility Model Content

[0004] The purpose of the utility model is to provide a weft-straightening device for dyeing, finishing and shaping of sofa fabrics, so as to solve the problem proposed in the above background technology that when the existing photoelectric weft-straightening machine is weft-straightening the sofa fabrics, due to the presence of impurities such as dust in the air, the dust and other impurities will move to the position above the photoelectric probe, so that the photoelectric probe is blocked by the dust and other impurities, and the weft line situation cannot be effectively judged, which leads to errors in weft straightening, affects the recognition accuracy, reduces the dyeing, finishing and shaping quality, and increases the cost of use if rework is done later.

[0018] 1.

[0039] The lower end of the support plate 23 is located outside the fixed shaft 21, and the upper end of the support plate 23 is a concave structure;

[0040] The support plate 23 can rotate along the fixed shaft 21, and when the support plate 23 rotates, the torsion spring 22 can be compressed;
