Abstract

The invention discloses an automatic locating breadth-variable weft insertion device and a working method thereof. The automatic locating breadth-variable weft insertion device comprises a weft cutter lifting mechanism, a yarn pressing mechanism, a weft cutter mechanism, a weft cutter horizontal moving mechanism and a rapier feeding mechanism which are installed on a rack, wherein the weft cutter lifting mechanism, the yarn pressing mechanism, the weft cutter mechanism and the weft cutter horizontal moving mechanism are located on one side of the rack; the rapier feeding mechanism is located on the other side of the rack; the weft cutter horizontal moving mechanism can drive the weft cutter lifting mechanism to horizontally move frontwards and backwards; the yarn pressing mechanism and the weft cutter mechanism can move up and down along the weft cutter lifting mechanism; the rapier feeding mechanism comprises a yarn clamping mechanism, a rapier, a rapier feeding linear module and a rapier lifting mechanism; the rapier feeding linear module can drive the yarn clamping mechanism and the rapier to horizontally move frontwards and backwards; and the rapier lifting mechanism can drive the yarn clamping mechanism and the rapier to move up and down. According to the invention, the same weft insertion device can be suitable for fabrics with different breadths in a weaving process, and the problem that the position of a cloth fell changes continuously in the weaving process is solved.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to an automatic position-seeking variable-width weft insertion device and a working method thereof. Background technique [0002] With the rapid development of engineering technology and material science, industrial production has higher and higher requirements on material performance. Because of its unique and excellent performance, fiber composite materials are widely used in aerospace, wind power generation, shipbuilding and other fields, especially in the aircraft manufacturing industry. For advanced composite materials, its research, development and application have gradually become one of the core contents of high-tech material technology. [0003] The core technology of composite three-dimensional fabric forming is the key technology research and application of open weft insertion, so the research on composite three-dimensional fabric weft insertion technology is particular...
