Problems solved by technology

When the transmission shaft drives the mandrel of the bending roller to rotate, due to the radial runout of the transmission shaft and other factors, the sprocket is easily fatigued and damaged, which often causes poor chain transmission, increases power consumption, accelerates the wear of the chain and sprocket, and the chain is easy to stretch breakage, or even accidents, which is not conducive to safe production, affects the normal supporting operation of the dyeing and finishing process, high maintenance costs, and increases the cost of use
[0006] Moreover, the existing weft straightening machine uses a plurality of straight rollers and bending rollers to correct the fabric distortion by adjusting the fabric stroke. Correction of skew and weft / flower-shaped bending, and the correction amount cannot be fine-tuned precisely, resulting in low correction accuracy, and cannot achieve fine and precise correction of the entire fabric; on the other hand, the existing weft alignment machine needs to pass through multiple straight rollers, The bending roller corrects the fabric, the mechanical structure is relatively complicated, and the adjustment stroke is also long. It is a system with a large delay, and the response is slow, which is not conducive to real-time correction control. It cannot be adjusted with high precision, and the product quality is difficult to improve; on the other hand, Because the existing weft adjusting machine exerts tension on the fabric across the entire width, too large or too small will cause the fabric in the weft adjusting machine to be over-drawn or piled up, so it is easy to cause the fabric to be over-drawn and curled; in addition, the existing weft adjusting machine The machine cannot effectively correct some knitted fabrics that are highly extensible and easily deformed by external forces, and fabrics with loose structures such as chiffon, etc., and the application range is small.
For these problems, there is currently no solution

Embodiment approach

[0042] As a preferred embodiment of the present invention, the method also includes that after step (1) and before step (2), the detection mechanism collects the weft yarn and pattern status data of the fabric 10 in operation, and transmits the collected data to Electric controller steps. In addition, in step (1), each sleeve is preferably controlled by an electric controller to actively rotate at the same rotational speed and pull the fabric, of course, it can also be driven to rotate passively by the fabric.

[0043] As a preferred embodiment of the present invention, step (2) specifically includes: performing the following control according to the direction of fabric weft skew / flower shape skew and weft bend / flower shape bending, the position of the variation area in the width direction, and the amount of variation,

[0044] (2-1) When the weft skew / flower shape skew or weft bend / flower shape bending direction of the fabric is consistent with the running direction of the fa...

Abstract

The invention discloses a fabric texture and pattern correction method and a weft straightener. The weft straightener comprises a plurality of correction rollers, a detection mechanism for detecting fabric texture and pattern and an electric controller; the correction rollers are installed on a rack of the weft straightener and arranged in the fabric width direction; the detection mechanism is connected with the electric controller; the correction rollers are controlled by the electric controller; each correction roller comprises a shaft and at least three sleeves arranged on the shaft in a sleeving mode; each sleeve is controlled by the electric controller to rotate independently; the two ends of each shaft are fixedly installed on the rack of the weft straightener; each sleeve is rotationally arranged on the corresponding shaft in a sleeving mode through a bearing; each sleeve is driven by a corresponding driving mechanism to rotate; and all the driving mechanisms are controlled by the electric controller. According to the invention, local areas, small fragments and irregular weft skewing / pattern skewing and weft bending / pattern bending can be corrected, the correction amount can be accurately and finely adjusted, real-time correction can be realized, the response speed is high, the correction precision is high, excessive drafting or cloth piling is avoided, the structure is simple, the use cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to a correction method and equipment, in particular to a fabric texture and flower shape correction method and a weft trimming machine, which belong to the technical field of textile equipment and technology. Background technique [0002] In the process of weaving and finishing, due to the influence of equipment precision errors, various mechanical movements and human operations, weft skew, weft bend, flower shape skew and flower shape bending often occur, which affects subsequent processing and thus affects the quality of finished fabrics. Quality, reducing the use value of textiles, therefore, it is necessary to use the weft straightening machine to correct the distortion of fabric texture and flower shape. [0003] The existing weft straightening machine includes several straightening rollers, a detection mechanism for detecting fabric texture and flower shape, and an electric controller. The straightening rollers include strai...
