Abstract

The invention discloses a fabric correction method and a flexible weft straightener. The flexible weft straightener comprises a fabric correction device, a fabric detection device and an electric controller; the fabric detection device is connected with the electric controller; the fabric correction device is controlled by the electric controller; the fabric correction device comprises at least three correction mechanisms which are arranged in the fabric width direction and provided with independently-driven rotating pieces; the rotation of the rotating pieces is controlled by the electric controller; each correction mechanism comprises a shaft, a sleeve mounted on the shaft and a driving mechanism; the shafts are mounted on a rack of the flexible weft straightener or an independently-arranged bearing frame; the sleeves serve as the rotating pieces and are driven by the driving mechanisms to rotate; and the driving mechanisms are controlled by the electric controller. According to the invention, local areas, small fragments and irregular weft skewing, weft bending and pattern deformation 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 correction method for fabric weft skew, weft bend and pattern deformation and a weft trimming machine, belonging 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] Existing weft straightening machines include several straightening rollers, a fabric detection device for detecting fabric texture and flower shape, and an electric controller. The straightening ...

Examples

Embodiment approach

[0044] As a preferred embodiment of the present invention, the method also includes collecting the weft yarn and flower shape of the running fabric 13 by the fabric detection device before the rotating member corrects the weft yarn or flower shape deformation and / or after the rotating member corrects the weft yarn or flower shape deformation. State data, and the step of transmitting the collected data to the electric controller.

[0045] As a preferred embodiment of the present invention, the electric controller controls the rotational speed and / or steering of the rotating parts in the weft yarn or flower-shaped deformation area, and the rotating parts in the weft yarn or flower-shaped deformation area contact the fabric to correct the weft yarn or flower-shaped deformation, Specifically: perform the following control according to the weft skew, weft bend or flower shape deformation, the area position and the variation amount of the width variation of the fabric,
