Fabric weft straightening or weft straightening and pattern straightening mechanism and method

Abstract

The invention discloses a fabric weft straightening or weft straightening and pattern straightening mechanism and method. The fabric weft straightening or weft straightening and pattern straighteningmechanism comprises a correcting mechanism, a detecting mechanism and a central processing unit. The correcting mechanism comprises a first spreading roller, a second spreading roller and multiple correcting rollers. The first spreading roller is driven by a first motor, the second spreading roller is driven by a second motor, and the multiple correcting rollers are driven by a driving mechanism.The first spreading roller is arranged on one side of fabric in the width direction, the second spreading roller is arranged on the other side of the fabric in the width direction, and the multiple correcting rollers are arranged in front of the first spreading roller and the second spreading roller along the fabric running route. The detecting mechanism is arranged in front of and / or behind the first spreading roller and the second spreading roller along the fabric running route. The first motor, the second motor, the driving mechanism and the detecting mechanism are controlled by the centralprocessing unit. According to the fabric weft straightening or weft straightening and pattern straightening mechanism and method, the correction control can be conducted in real time, the correctionresponse speed is high, the fabric is not damaged in the correction process, the use cost is low, the applicable textile variety range is wide, the correction precision is high, and the effect is better.

Description

technical field [0001] The present invention relates to a mechanism and method for correcting weft skew, weft bend, flower shape skew and flower shape bend of fabrics, in particular to a fabric weft adjustment or weft adjustment and flower adjustment mechanism and method, belonging to the technical field of textile equipment and technology . Background technique [0002] Weft skew is the skewed state in which the weft or knitted fabric course deviates from a straight line perpendicular to the warp or wale of the fabric. Bow weft (weft bend) is the weft or knitted fabric course deviates from a straight line perpendicular to the warp or wale of the fabric. Direction forms one or more arc skew states. The weft yarn mentioned in the present invention refers to the weft yarn of the woven fabric or the course of the knitted fabric. [0003] Woven fabrics are made of warp yarns and weft yarns that are perpendicular to each other and are interwoven at a 90-degree angle. The longit...

AI Technical Summary

Problems solved by technology

For non-elastic fabrics, after adjusting the angle of the straightening rod, the full-width inward fabric will no longer completely cover the straightening rod, and the fabric will hang, and the weft skew / bend cannot be corrected at all. Therefore, the non-elastic fabric cannot be corrected at all. roller weft

[0015] For high-elastic fabrics, the correction rod or needle wheel does not have sufficient weft strength, and the weft yarn of the corrected fabric is easy to return to its original shape, neither of which can effectively improve weft skew / bend

[0016] In summary, the above-mentioned pin wheel weft adjusting device and roller weft adjusting device have defects such as complex structure, long adjustment stroke, poor weft correction effect, and limited types of applicable textiles.

It can be seen that with the rapid development of textiles, the renewal of fabric fibers and weaving technology, and the unreasonable bending of fabrics, the existing technology can no longer meet the correction of weft skew, weft bending, and flower shape skewing. Solve the existing difficulties, reproduce the flower shape, texture, style and basic organizational structure of the textile surface, improve the use value of textiles, and improve product quality
