Problems solved by technology

According to the characteristics of composite materials and medical materials and the requirements of weaving technology, when weaving composite multi-layer prefabricated parts and artificial blood vessel tubular fabrics on medical textiles, due to the non-abrasion resistance of the fibers, the breakage rate is too high, and the efficiency is extremely low or even It cannot be weaved normally; and because the weaving of multi-layer prefabricated parts of composite materials requires the integrity of the prefabricated parts, the weft yarn must be continuously woven; and the current production of prefabricated parts made of composite materials is mostly manual picking, and the production efficiency is very high. Low

Abstract

The present invention relates to a shuttle weft insertion apparatus with tracks. The shuttle weft insertion apparatus with tracks comprises a fixed support, heald frames, a reed, a shuttle box and a picking mechanism; The fixed support is also provided with telescoping guide tracks having a non-closed shaped cross section, track telescoping driving mechanisms and linear guide rails; each telescoping guide track comprises a front track entering a shed; a position, close to the tail end, of each telescoping guide track is fixed to a sliding block of the corresponding linear guide rail; and the track telescoping driving mechanisms are fixed to the fixed support, and a piston end of each track telescoping driving mechanism is connected with the tail end of the corresponding telescoping guide track via a connecting piece. According to the shuttle weft insertion apparatus with tracks, upper and lower layer warp yarns in the shed are prevented from extrusion and friction, the shuttle is a conventional large shuttle, the weft storage amount is large, the shuttle is not required to be replaced frequently, and stability of the shuttle flying in the tracks is ensured. When multilayer weavingof composite materials is carried out, weaving efficiency is high, and safe and convenient production can be provided for automatic picking and weft insertion modes of weaving of multilayer prefabricated components of composite materials.

Description

Technical field [0001] The invention relates to the field of textile machinery, in particular to a shuttle weft insertion device with a track. Background technique [0002] The shuttle weft insertion device of the conventional loom is a conventional single-layer fabric weaving method. The weft is introduced into the shed by the shuttle. The shuttle is used as both a weft inserter and a weft accumulator. The shuttle enters from one end of the shed and exits from the other end of the shed. The shuttle flies freely in the shed. It is a relative movement along the sley. . The shuttle is the movement of the lower yarn rolled in the shed, which will cause squeeze and friction on the warp yarn during the movement. According to the characteristics of composite materials and medical materials and the requirements of weaving technology, when weaving composite material multilayer preforms and artificial blood vessel tubular fabrics on medical textiles, due to the non-abrasion resistance o...
