Problems solved by technology

[0003] The weaving technology of three-dimensional woven fabrics is very difficult. The existing three-dimensional fabric looms are high in cost and low in efficiency, and the degree of interlayer bonding is not high, which cannot meet the needs of various structures.
The more layers of warp yarns, the more pages of heald frames are required, the opening width of warp yarns (especially vertical yarns) is also large, the deformation of shed opening is greatly increased, and the definition of shed opening is reduced; the arrangement density of warp yarns is also higher. Increased wear between warp yarns and between warp yarns and heddles, these problems may not only cause frequent breakage of warp yarns, but also bring difficulties to weft insertion

Abstract

The invention provides an opening device for a stereo loom. The opening device contains healed frames and is characterized in that at least one healed frame is connected with multi-hole palm fiber; at least one healed frame is connected with a push rod, which is connected with a servo electric cylinder; and the servo electric cylinder is connected with a driver, which is connected with a computer. By the adoption of the opening device, the number of heddles can be minimized and high-speed and digitalized control is carried out on the motion of the healed frames, thus greatly expanding types and specifications of fabrics and reducing abrasion of palm fiber to warp yarn.

Description

technical field [0001] The invention relates to an opening device for a three-dimensional loom, belonging to the technical field of textiles. Background technique [0002] Three-dimensional weaving technology is a new type of textile technology, which enables fibers to be distributed in multiple directions in three-dimensional space and intertwined with each other to form a non-layered overall structure. It has many advantages such as high strength, excellent mechanical properties, etc., and has been widely used in many fields such as aerospace, national defense and military industry, transportation, and energy, and has been continuously expanded to the civilian field. [0003] The weaving technology of three-dimensional woven fabrics is difficult, and the existing three-dimensional fabric looms have high cost, low efficiency, and low interlayer bonding, which cannot meet the needs of various structures. At present, most of the 3D looms developed in China are in manual or s...
