Abstract

The invention discloses a three-dimensional multilayer pneumatic picking loom, comprising a wallboard a and a wallboard b which are arranged in parallel, and a rack beam used for supporting is horizontally arranged between the wallboard a and the wallboard b. A horizontal weft insertion mechanism is supported on the wallboard a and the wallboard b. An open harness frame, a weft insertion going part, and a closing mechanism are arranged in sequence along a horizontal moving direction of warp yarns between the wallboard a and the wallboard b. The open harness frame, the weft insertion going part, and the closing mechanism are arranged along a vertical direction and are parallel to each other. The open harness frame is arranged close to the weft insertion mechanism. A yarn carrying device is also arranged between the wallboard a and the wallboard b. Latch needles are arranged under the yarn carrying device. The yarn carrying device is arranged close to the closing mechanism. The inner side of the wallboard b is provided with a main nozzle along a vertical direction. The loom is used to solve problems of an existing three-dimensional loom that automation degree is low and weaving efficiency is low.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a three-dimensional multilayer air-jet weft insertion loom. Background technique [0002] As a prefabricated part of textile structural composite materials, three-dimensional woven fabrics have been widely used in many fields such as aviation, aerospace, automobiles, and ships because of their light weight, good integrity and profiling, and excellent mechanical properties. application. However, the technical difficulty of making three-dimensional woven fabrics is high, the cost is high, and the output is small, and sometimes it cannot meet the needs of the structure well. Therefore, how to weave integral woven fabrics with three-dimensional interwoven structure has become one of the important research topics in the field of composite materials in recent years. The weaving technology of three-dimensional woven fabrics has developed rapidly. At present, various weaving met...
