Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile machinery, in particular to a special-shaped rotary body warp and weft density profiling control device. BACKGROUND

[0002] With the rapid development of engineering technology and material science, the requirements of industrial production on material performance are also becoming higher and higher. The use of woven fabric laying of special-shaped components has the problems of discontinuous fiber layer and poor designability of fiber direction, and the performance of some components with high bearing capacity requirements in the fields of aviation and aerospace cannot meet the requirements. Therefore, the profiling weaving process is adopted to conduct overall weaving of the fiber reinforced fabric according to the profile requirements, and the woven fabric has the characteristics of continuous fiber, designed fiber direction according to material requirements, and high accuracy of profile wrapping and pasting. In order to realize the profiling weaving of the space curved surface and control the uniformity of the woven fabric, the profiling reed is used to control the position change of the weaving mouth and the generatrix in the weaving process, the planar profiling of the rotary body fabric is realized, and the warp and weft density of the fabric is controlled by the profiling reed to ensure the uniformity of the warp and weft density of the special-shaped fabric.

The fabric produced by using the steel reed with a concave-convex beating-up surface breaks through the traditional horizontal and vertical organizational structure. The steel reed of the patent mainly uses different shaped reed pieces to control the uniformity of the warp density of the fabric and the difference of the weft density, and the reed pieces are arranged in the same plane. For the control of the overall weft density and the uniformity of the warp density of the fabric of the patent, the weaving mouth is not in the same plane, and the patent cannot be realized.

[0004] Publication No. CN103820930A discloses a variable special-shaped reed. The reed mainly plays a role in guiding weft in the weaving process of a jet loom by changing the shape of the reed teeth, and the reed can change the width. However, it cannot control the shape of the weaving mouth for different fabric profiles.

[0005] Publication No. CN112430880A discloses a method for changing the warp yarn distribution of a fabric by adjusting the width of the reed teeth. Without changing the reed insertion process, the width and arrangement of the steel reed teeth are adjusted to form an equidistant distribution of concave-convex structures on the front surface of the steel reed. During weaving, the warp yarn distribution of the fabric is changed, and the fabric surface presents a regular dense and sparse stripe effect along the warp direction. The patent mainly realizes the change of the warp density and the weft density of the fabric, and for the control of the overall weft density and the uniformity of the warp density of the fabric of the patent, the weaving mouth is not in the same plane, and the patent cannot be realized.
