TECHNICAL FIELD

[0001] The utility model relates to the field of textile, concretely relates to a kind of anti-bending light roll for textile printing and dyeing equipment and weft straightener, printing and dyeing post finishing equipment. BACKGROUND

[0002] Weft straightener and printing and dyeing post finishing equipment etc. are widely used equipment in textile industry, and are common textile printing and dyeing equipment. Weft straightener is used to correct weft bending and weft skew of fabric to ensure the quality and appearance of fabric. Printing and dyeing post finishing equipment such as setting machine is mainly used to finish and set the fabric after printing and dyeing.

[0003] Weft straightener has good weft straightening effect on woven fabric, but when it is used to straighten high-elastic knitted fabric such as knitted weft-knitted fabric and knitted warp-knitted fabric, the fabric is easily deformed due to tension during the straightening process because the passive rollers such as straightening roller and guide roller are heavy and have large rotational damping. When the fabric passes through the guide roller, it is also easily deformed because the guide roller is heavy and has large rotational damping and inertia.

[0004] The inventor of the present patent replaces part or all of the passive rollers with light rollers to solve the above problems in textile printing and dyeing equipment. The roller body of the light roller is light, has small rotational damping and small inertia, which can solve the problems of poor weft straightening effect of weft straightener on high-elastic knitted fabric and easy deformation of fabric when passing through the guide roller in printing and dyeing post finishing equipment.

[0005] However, it is found that the light roller has relatively poor deformation resistance during actual use, especially the relatively long light roller (generally 1500-4000 mm in length), which is easily bent in the middle part, affecting the quality of the fabric. SUMMARY
