Description

Technical Field

[0001] The invention relates to the technical field of weft straightening of fabrics, in particular to a weft straightening or weft straightening and pattern straightening mechanism and method for fabrics. Background Art

[0002] During the weaving and finishing process of fabrics, due to the influence of equipment accuracy errors, various mechanical movements and human operations, weft skew, weft bend, flower shape skew and flower shape bend often occur, which affect the subsequent processing, thus affecting the quality of the finished fabric and reducing the use value of the textiles. Therefore, it is necessary to use a weft straightening device to correct the weft yarn distortion. The current weft straightening devices mainly include pin wheel weft straightening devices and roller weft straightening devices;

[0003] The pinwheel weft straightening device has two pinwheels that are completely free-rotating passive bodies without any active power. In order to reduce the rotation damping torque of the pinwheels and improve the weft straightening effect, the processing accuracy of the pinwheels and the matching parts are very strict. The pinwheel diameter is usually 500-1000 mm. The pinwheel is large in size, difficult to process and expensive. When the pinwheel passes through the seam head, the needle of the pinwheel is easy to break. If it cannot be repaired, the entire pinwheel will be scrapped. The maintenance cost of the pinwheel weft straightening device is high.

[0004] When using a roller-type weft straightening device to straighten the weft, if the fabric width is smaller than the working width of the straightening roller, the straightening efficiency will decrease accordingly. Moreover, the fabric must be in a good centered state when entering the roller-type weft straightening device, otherwise the bend will increase the degree of deformation exponentially. For knitted fabrics with large extensibility and easily deformed by external forces, loose chiffon and low-elastic woven fabrics, because the structure of these fabrics is easy to produce elasticity, they will still return to the original deformed state even after being straightened by the straightening roller;

[0005] In summary, the above-mentioned pin wheel weft straightening device and roller weft straightening device both have defects such as complex structure, long adjustment stroke, poor weft correction effect, and limited applicable textile types. Summary of the invention

[0020] S1. Install a detection component in the middle of the upper part of the two active rollers, collect the weft yarn and pattern conditions of the running fabric through the detection component, and transmit the collected data to the central processing unit. The detection system is preferably an industrial camera, such as a linear array camera or a planar array camera. When the central processing unit determines that weft skew / pattern skew occurs, the weft skew / pattern skew is corrected by adjusting the speed difference between the two active rollers. The residual weft skew / pattern skew and weft bend / pattern bend of the fabric after it passes through the two active rollers are corrected by the bending roller and the straight roller.

[0021] S2. When the longitudinal angle of the active roller needs to be adjusted, the motor 1 is started to drive the gear 2 to rotate, and the gear 1 and the rotating shaft 1 can be driven to rotate under the meshing action to complete the longitudinal angle adjustment of the active roller. When the lateral angle of the active roller needs to be adjusted, the motor 3 is started to drive the rotating rod and the gear 3 to rotate, and the gear 4 and the rotating shaft 2 are driven to rotate under the meshing action to complete the lateral angle adjustment. By adjusting the active roller in different dimensions, the correction effect of the fabric can be improved;

[0023] S4. The corrected fabric enters the cleaning box, and the dust suction fan is started to send the dust and lint attached to the surface of the fabric into the dust suction box through the dust suction pipe, completing the weft straightening and cleaning of the fabric.

[0024] Working principle: When in use, the detection component is installed in the middle above the two active rollers. The detection component collects the weft yarn and pattern conditions of the running fabric, and transmits the collected data to the central processing unit. The central processing unit receives the data of the detection component and processes it to determine whether weft skew, weft bend, pattern skew and pattern bending occur. When the central processing unit determines that the fabric has weft skew / pattern skew, it corrects the weft skew / pattern skew by adjusting the speed difference between the two active rollers 206. The residual weft skew / pattern skew and weft bend / pattern bending of the fabric after passing through the two active rollers 206 are corrected by the bending roller 102 and the straight roller 101. When the longitudinal angle of the active roller needs to be adjusted, the motor 1 202 is started to drive the gear 2 204 is rotated, and can drive gear one 203 and shaft one 201 to rotate under the meshing action, so as to complete the longitudinal angle adjustment of the active roller 206. When the lateral angle of the active roller 206 needs to be adjusted, the motor three 301 is started to drive the rotating rod 303 and gear three 302 to rotate, and drive gear four 305 and shaft two 304 to rotate under the meshing action, so as to complete the lateral angle adjustment. By adjusting the active roller 206 in different dimensions, the correction effect of the fabric can be improved. After passing through the two active rollers 206, the fabric can enter the straight roller 101 and the bending roller 102 in turn, and the fabric is corrected twice by the straight roller 101 and the bending roller 102, thereby improving the practicality of the entire device.

[0025] (III) Beneficial effects

[0026] The present invention provides a weft straightening or weft straightening and pattern straightening mechanism and method for fabrics, which have the following beneficial effects:

[0027] 1. The present invention provides two active rollers at both ends of the equipment that can be adjusted differently. By adjusting the speed difference or angle difference between the two active rollers, the weft skew / pattern skew can be quickly corrected. The residual weft skew / pattern skew and weft bend / pattern bend of the fabric after it passes through the two active rollers are corrected by the bending roller and the straight roller, thereby achieving secondary correction and improving the weft straightening effect of the entire mechanism.

[0028] 2. The present invention can make the threaded block drive the bending roller to adjust up and down by setting the screw assembly, so as to adjust the tightness of the fabric, thereby preventing the fabric from being too loose or too tight during the correction process, resulting in poor weft straightening effect;

[0029] 3.
