Problems solved by technology

Although this method achieves the effect of introducing multiple wefts, it still uses a single weft yarn for weft insertion, which loses the high-efficiency feature of simultaneously introducing multiple wefts, and when the second weft yarn is introduced, the airflow of the main and auxiliary nozzles will be on the front Weft yarns that do not interweave with warp yarns
Therefore, there is no device or method that can really break through the current situation of more than 2 weft insertions in a single weft insertion at present.

Embodiment 1

[0034] Embodiment 1, with organization chart as image 3 Taking three wefts as an example in the through-hole weave, the heald is drawn in the way of flying through, and the weft yarns are alternately drawn with three wefts and one weft to form a through-hole fabric:

[0035] A method for breaking through the limitation of the single weft insertion quantity of an air-jet loom, comprising the following steps,

[0036] Step 1, arranging the weft yarn 1, placing the weft yarn 1 required for production on the weft creel;

[0037] Step 2, the three weft yarns 1 are passed through the guide holes 15 of two existing weft detectors 2 and the guide holes 14 and pinholes 12 of a weft stop detection mechanism 3 respectively, and then the three weft yarns 1 are combined Store and wind on one of the weft feeders 4, insert a part of the weft yarn 1 through the yarn guide hole 15 of the existing weft finder 2, and then store and wind this weft yarn 1 on another weft feeder 4 ;

Embodiment 2

[0042]Embodiment 2, with organization chart as Figure 6 Take the 4 / 4 basket weave as an example, adopt the method of threading through the heddle, and the four wefts of the weft thread alternately form a square fabric:

[0043] A method for breaking through the limitation of the single weft insertion quantity of an air-jet loom, comprising the following steps,

[0044] Step 1, arranging the weft yarn 1, placing the weft yarn 1 required for production on the weft creel;

[0045] Step 2, the eight weft yarns 1 are divided into two groups of four, the first group of four weft yarns 1 respectively pass through the guide holes 15 of the two existing weft detectors 2 and the guide holes 14 of the two weft stop detection mechanisms 3 and pinhole 12, and then the four weft yarns 1 are stored and wound together on one of the weft feeders 4 of a group of weft feeders 4, and the other group of four weft yarns 1 is stored and wound on another weft feeder in the same way 4 on;

Abstract

The invention belongs to the field of air-jet loom spinning, and relates to a system and method for breaking through the limitation of the single weft insertion number of an air-jet loom. The system comprises a weft detector and a weft accumulator, wherein the weft detector is arranged at a front station of the weft accumulator, a rear station of the weft accumulator is a main nozzle, a weft rackis arranged at the front station of the weft detector, a yarn guide hole is formed in the weft detector, and a weft stop detection mechanism is arranged at the parallel station of the weft detector. According to the system and method, three or more pieces of weft yarn and warp yarn can be interwoven, the working process is stable and reliable, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to a system and a method for breaking through the limit of single weft insertion quantity of an air-jet loom, belonging to the field of air-jet loom textiles. Background technique [0002] At present, due to the high speed of the air-jet loom and the narrow weft insertion channel, the number of nozzle holes in the main nozzle is limited. Generally, the main nozzle of the air-jet loom only has four spray holes, and the corresponding weft feeders are only four. The four weft feeders of the loom are divided into two groups, and the two groups alternate actions to complete the weaving; In the case of transformation, the air-jet loom can only draw double wefts for weaving. For example, the patent application publication number CN109487410A discloses a weaving method using an air-jet loom to weave multi-warp and multi-weft series fabrics. The method introduces a pattern plate of a virtual pattern through editing, and the introduced vir...
