In the existing weft straightening machine, a plurality of straight rollers are installed in a weft inclined frame, the weft inclined frame is provided with a rotating shaft, one side of the weft inclined frame is provided with a driving assembly for driving the weft inclined frame to rotate, and a detection potentiometer cannot completely and accurately reflect the actual position state of the straight rollers in the weft inclined frame due to various factors such as movement gaps between racks and gears, so that the correction effect of the fabric weft inclination can be influenced; in addition, the open structure of the rack and the gear needs to be maintained frequently, so that the use cost of the equipment is increased.
The existing bending roller in the weft straightening machine drives a bending roller mandrel to rotate through a motor and a transmission shaft and a chain wheel and chain transmission mechanism, and the shaft body of the transmission shaft is rotationally connected with a frame of the weft straightening machine.

Moreover, the existing weft straightening machine corrects the fabric distortion by using a plurality of straight rollers and curved rollers through adjusting the fabric stroke, on one hand, the existing weft straightening machine cannot correct the skew and the bending of the weft/the flower shape in a local area, a small segment and irregularity, and the correction amount cannot be finely adjusted, so that the correction precision is low, and the full-width fabric cannot be finely and accurately corrected; on the other hand, the existing weft straightening machine needs to correct the fabric through a plurality of straight rollers and bending rollers, is relatively complex in mechanical structure, relatively long in adjustment stroke, belongs to a system with relatively large delay, is slow in response, is not beneficial to real-time correction control, cannot finish weft with high precision, and is difficult to improve the product quality; on the other hand, the existing weft straightening machine applies tension to the fabric in the whole width, and the excessive stretching or the stacking of the fabric in the weft straightening machine can be caused by the excessive stretching or the excessive pressing of the fabric, so that the phenomena of excessive stretching and edge curling of the fabric are easy to occur; in addition, the existing weft straightening machine cannot effectively correct some knitted fabrics which have large extensibility and are easy to deform under external force, and fabrics with loose structures such as chiffon, and has a small application range. No solution is currently available to these problems.

After the technical scheme is adopted, the invention has the following beneficial effects:
the invention preferably adopts a correcting roller which comprises at least three independent correcting rollers arranged at intervals along the radial direction of the fabric, each independent correcting roller comprises a shaft and a roller sleeved on the shaft, the rollers are controlled by an electric controller to rotate independently, and the electric controller controls the rotating speed and/or the rotating direction of the rollers in the weft or the flower-shaped distortion area according to the weft or the flower-shaped distortion condition of the fabric so as to correct the weft or the flower-shaped distortion. When the device works, a fabric width correction area is thinned in sections, the rotation speed and/or the rotation direction of a roller positioned in a weft yarn or pattern distortion area are controlled by an electric controller, partial areas, small segments and irregular weft skew/pattern skew and weft bend/pattern bend are effectively corrected, the correction amount can be independently and accurately fine-tuned individually during correction, the response speed is high, the speed regulation range is large, the correction precision is high, the local weft skew/pattern skew or weft bend/pattern bend at a certain part of a textile, the weft skew/pattern skew without irregular shape and complicated confusion or weft bend/pattern bend, full-width straight lines, arcs, suspension angle weft skew/pattern skew or weft bend/pattern bend and the like can be well corrected; moreover, no specific requirements are required for the weave structure parameters of the fabric and the offset of weft yarns, and skew/skew and warp/twist bending which cannot be corrected by the conventional straight roller and curved roller can be finished.
The invention can only correct tension corresponding to the distorted part of the fabric, so that excessive drafting or stacking can not occur, and the problems of excessive drafting or stacking of the fabric in the weft straightener caused by excessive or insufficient tension applied to the fabric by the existing weft straightener are solved.
The invention can correct the knitted fabrics which have large extensibility and are easy to deform under the external force and the fabrics with loose structures, such as chiffon and the like, which cannot be corrected by the existing straight rollers and bending rollers, and has wide application range. The weft skew/warp skew of the knitted fabric is that the stitches deviate from a straight line vertical to the wale of the fabric, namely, the courses of the knitted fabric connected together in series leave a balanced state, and the conventional weft straightening machine usually corrects the fabric in a full width, but cannot achieve the aim of effective correction. The invention can accelerate or reduce the roller line speed of the area at the initial part of the crosswise row stitch bending of the knitted fabric, so that the area is recovered to be vertical to the straight line of the wale of the knitted fabric, and other stitch bending can be corrected by being connected with the initial part in series.

And in the straight roller and the bending roller in the prior art, if the width of the fabric is smaller than the working width of the straight roller and the working width of the bending roller, the correction efficiency is correspondingly reduced, the correction effect is greatly reduced, moreover, the fabric enters the existing weft straightening machine and must be in a good centered state, otherwise, the bending roller can increase the deformation degree in a doubling way. Therefore, the invention has no limit to application conditions, and greatly optimizes the weft straightening working conditions.
The invention changes the linear speed of the correcting roller only by increasing or reducing the same speed increment for all the rollers simultaneously, thereby obtaining the weft straightening tension required by the process and being very beneficial to realizing high-precision fabrics. Compared with the prior art, when the low-elasticity woven fabric is used for weft straightening, after the angle of the straight roller is adjusted, the full-width inward fabric does not completely cover the straight roller any more, the fabric is suspended, and weft skew/weft bending cannot be accurately corrected, so that the application range of the low-elasticity woven fabric is wider.
The invention has the advantages of simple and reasonable structure, low use cost, convenient installation, simple and convenient operation, convenient maintenance and high reliability.
