Description

Correcting device for correcting weft pattern of fabric weft

Technical Field

The utility model relates to a correcting device for correcting the pattern of weft lines of fabric weft in a weft straightening machine, belonging to the technical field of textile printing and dyeing equipment.

Background

The straightening device used by the existing weft straightening machine generally adopts a straightening roller, and the straightening roller comprises a straight roller for straightening weft skew and a curved roller for straightening weft bending; the straight roller is arranged in the oblique weft frame, and the oblique weft frame can be driven to rotate, so that the straight roller and the fabric weft yarn are not parallel any more, and the oblique weft is corrected; the bending roll is characterized in that a steel sleeve with a rubber roll surface is movably sleeved on a bending roll mandrel, the steel sleeve can rotate around the bending roll mandrel, the bending roll mandrel can also rotate, and the steel sleeve can correct the weft bending when rotating; when the fabric is tightly attached to the surface of a straight roller or an arc rubber roller with a certain pressure, the relative running speed of the warp yarns of the fabric is changed, and the corresponding part of the inclined weft yarns is led to be ahead or behind, so that the vertical intersection of the weft yarns and the warp yarns in the whole width is restored, and the effect of straightening the weft yarns by the straightening roller is achieved.

However, because the straight roller and the curved roller correct the deformation of the fabric by adjusting the stroke of the fabric, the following defects exist in the work: on one hand, the straight roller and the curved roller can not correct local areas, small segments, irregular weft skewing, weft bending and pattern deformation, and the correction amount can not be finely adjusted accurately, so that the correction precision is low, and the full-width fabric can not be refined and accurately corrected; on the other hand, the straight roller and the curved roller have complicated mechanical structures and longer adjusting stroke, belong to a system with larger time delay, have slow response, are not beneficial to real-time correction control, cannot finish weft with high precision, and are difficult to improve the product quality; on the other hand, the full width of the straight roller and the bending roller applies tension to the fabric, and the excessive large or small tension can cause excessive drafting or stacking of the fabric in the weft straightener, so that the phenomena of excessive drafting and edge curling of the fabric are easy to occur.

Disclosure of Invention

In order to solve the above technical problem, the present invention adopts such a correction device for correcting the pattern of weft of a woven fabric, comprising a correction belt and a driving mechanism for driving said correction belt to perform an endless movement, the driving mechanism being controlled by an electric controller.

In a preferred embodiment of the present invention, the driving mechanism includes a motor, a driving wheel and a driven wheel, the driving wheel is connected to the motor, the correction belt is in a ring shape and is installed between the driving wheel and the driven wheel, the driving wheel and the driven wheel are installed on the supporting frame, and the motor is controlled by an electric controller.

As a preferred embodiment of the utility model, the straightening devices are 3-50 and are arranged along the fabric width direction.

In a preferred embodiment of the present invention, the electric controller is a digital controller with a human-machine interface, or an embedded industrial controller, or an industrial personal computer, or a PLC programmable controller.

After the technical scheme is adopted, the utility model has the following beneficial effects:

when the correction device works, a fabric width direction correction area is segmented and refined, a local area, a small segment and irregular weft skew, weft bending or pattern deformation are effectively corrected by changing the running speed and/or the running direction of a correction belt positioned in a weft yarn or pattern deformation area, and during correction, the correction amount can be singly and independently and accurately finely adjusted, so that the response speed is high, the speed regulation range is large, the correction precision is high, and the local weft skew, weft bending or pattern deformation, the weft skew, weft bending or pattern deformation without irregular shape and complicated confusion, the full-width straight line, arc shape, suspension angle weft skew, weft bending or pattern deformation and the like at a certain part of a textile can be well corrected; moreover, no specific requirements are required for the weave structure parameters of the fabric and the offset of the weft yarns, and the skew weft yarns, warp weft yarns or pattern deformation which cannot be corrected by the conventional straight rollers and bending rollers can be finished.

The utility model can only correct tension corresponding to the deformed 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 due to the fact that the tension is applied to the fabric by the existing correcting roller in full width are solved.

The utility model 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 utility model can only accelerate or reduce the running speed of the correction belt in the area at the initial part of the crosswise row stitch bending of the knitted fabric so as to lead the area to be recovered to be vertical to the straight line of the wale of the fabric, and other stitch bending connected with the initial part in series can also be corrected.

The utility model has extremely low delay, faster response time and better performance; the properties of complicated mechanical structure, long adjusting stroke, large delay system and slow response in the prior art are completely avoided. The method overcomes the bottleneck of the prior art, and can correct the deformation conditions of small segments, irregularity and the like in real time.

The utility model can control the running speed of the correcting belt according to the requirement, can form various speed combinations in the width direction of the fabric, has no requirement on whether the fabric is centered and the width of the fabric when correcting the skewness, the warp or the deformation of the patterns, can self-adapt to the fabric feeding state when the fabric is corrected, and is convenient to use.

The utility model only needs to increase or decrease the same speed increment for all the correcting belts simultaneously, thereby obtaining the weft straightening tension required by the process and being very beneficial to realizing high-precision fabrics.

The utility model has simple and reasonable structure, convenient installation, high reliability and good correction effect.
