Description

Technical Field

[0001] The utility model belongs to the technical field of air jet looms, and particularly relates to a waste yarn passing structure of an air jet loom and an air jet loom. Background Art

[0002] Air jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. Their operating principle is to use air as the weft insertion medium, using the compressed air jet to generate frictional traction on the weft yarn, pulling it through the shed. This weft insertion method offers advantages such as a rational weft insertion method, high weft insertion rate, simple and safe operation, wide adaptability, low material consumption, high efficiency, high speed, and low noise, all while achieving high speed and high production.

[0003] However, although the existing air-jet looms have made many technological advances, they still have certain defects when used: the existing air-jet looms are limited by their own weft insertion structure, and a certain amount of waste yarn will inevitably be produced during the weaving process.

[0004] Currently, textile mills typically process the waste yarn produced by air-jet looms by first using weft-catching side shears to trim the waste yarn, leaving the fabric with a neat edge (raw edge). Warp guide wheels installed on both sides of the air-jet loom then transfer the waste yarn to waste yarn drums for storage. Consequently, over the long-term operation of air-jet looms, a large amount of unrecyclable waste yarn is generated, impacting product production efficiency. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a waste yarn passing structure for an air jet loom and an air jet loom, and to enable the repeated recycling of part of the waste yarn, so as to effectively solve the problem of waste yarn in the weaving process of the existing air jet loom and greatly improve the gross profit margin of the textile manufacturer.

[0006] In order to solve the above technical problems, on the one hand, the utility model provides a waste yarn passing structure for an air jet loom, which includes a warp tensioning shaft, a warp guide shaft, and waste warp yarns. The warp tensioning shaft is installed upstream of the weft insertion unit provided on the upper part of the air jet loom, and the warp guide shaft is installed upstream of the cloth winding roller provided on the lower part of the air jet loom. A warp tensioning roller is rotatably installed in the middle part of the warp tensioning shaft, waste yarn tensioning plates are fixedly installed at both ends of the warp tensioning shaft, and a warp guide wheel is rotatably installed at the outer end of the warp guide shaft. The waste warp yarns include regular warp yarns and fixed warp yarns. The regular warp yarns pass through the warp tensioning rollers and the warp guide wheels in sequence. The ends of the fixed warp yarns are respectively fixedly connected to the waste yarn tensioning plates and the warp guide shafts, and the fixed warp yarns are located at the outermost side of all the waste warp yarns at the waste yarn position. Based on this, compared with the warp passing structure used in existing air jet looms, the utility model directly replaces the regular warp yarns located at the outermost position of the waste yarns with fixed warp yarns that have a fixed position and do not follow the middle regular warp yarns and the cloth. In this way, during the weaving process of the fabric, since the warp yarn at this location adopts a fixed structure and is located at the outermost position of all warp yarns, the fixed warp yarn can be reused to replace part of the original waste yarn and cooperate with the weft yarn to carry out the weaving operation of the edge of the fabric, thereby reducing the use of warp yarn and the amount of waste yarn generated, and effectively solving the problem of waste yarn in the weaving process of existing air-jet looms, thereby greatly improving the gross profit margin of textile manufacturers.

[0007] Furthermore, the total number of conventional warp yarns at the waste yarn position is 3. Since the present invention boldly changes the plain waste warp yarns from 4 to 3, it can effectively reduce material consumption.

[0008] Furthermore, the material of the fixed warp yarn is nylon yarn, and has high strength to ensure that it can meet the needs of multiple recycling uses, thereby achieving the purpose of energy saving and consumption reduction.

[0009] Furthermore, tensioning adjustment mechanisms are provided at both ends of the warp tensioning shaft, and the position of the warp tensioning shaft can be adjusted by the tensioning adjustment mechanism to ensure that the warp tensioning shaft can meet the tension adjustment requirements of the warp yarns.

[0010] Furthermore, a weft-catching side shear is provided upstream of the warp guide wheel, and the weft yarn at the edge of the cloth is cut by the weft-catching side shear to obtain a neat cloth edge.

[0011] On the other hand, the utility model also provides an air jet loom, which includes an air jet loom body, which is provided with the above-mentioned air jet loom waste yarn passing structure, and the above-mentioned air jet loom waste yarn passing structure is used to realize the reuse of part of the warp yarn during the weaving process, thereby achieving the purpose of energy saving and consumption reduction, and effectively improving the production efficiency of textile manufacturers.

[0012] It can be seen from the above technical scheme that the utility model has the following advantages: compared with the warp yarn passing structure in the existing air-jet loom, since the utility model reduces the number of ordinary warp yarns at the waste yarn position to 3, and uses fixed warp yarns as the outermost warp yarns at the waste yarn position, it can not only reduce the total number of waste yarns that cannot be reused, but also reuse the fixed warp yarns to replace part of the original waste yarns and cooperate with the weft yarns to carry out weaving operations on the edge of the cloth, thereby reducing the use of warp yarns and the amount of waste yarns generated, and effectively solving the problem of waste yarn waste in the weaving process of the existing air-jet loom, thereby greatly improving the gross profit margin of textile manufacturers. For example, based on the calculation of 0.0516 grams of single yarn waste per yard of cloth, according to the number of plain weave fabrics off the machine in a single month, it can save 103.27 kilograms of yarn waste, thus achieving significant results.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figure 1As shown, this embodiment 1 provides a waste yarn threading structure for an air jet loom, comprising a warp tensioning shaft 2, a warp guide shaft 7, and waste warp yarns. The warp tensioning shaft 2 is mounted upstream of a weft insertion unit located on the upper portion of the air jet loom, and a warp tensioning roller 4 is rotatably mounted in the middle of the warp tensioning shaft 2. A waste yarn tensioning plate 3 and a tensioning adjustment mechanism are fixedly mounted at each end of the warp tensioning shaft 2 (as this tensioning adjustment mechanism is conventional in the art, it will not be described in detail here).

[0019] The warp guide shaft 7 is installed upstream of the cloth winding roller provided at the lower part of the air-jet loom, and the outer end of the warp guide shaft 7 is rotatably installed with a warp guide wheel 8, and a weft catching side shear is provided upstream of the warp guide wheel 8 (since the weft catching side shear is a mature existing technology, it will not be described in detail here), and the weft yarn at the edge of the cloth is cut by the weft catching side shear to obtain a neat cloth edge.

[0020] The waste warp yarns include three regular warp yarns 6 and one fixed warp yarn 5. The regular warp yarns 6 are threaded in the same manner as the waste warp yarns in existing air-jet looms, starting from the warp unwinding shaft, passing through the warp tensioning roller 4 and the warp guide wheel 8, and then entering the waste yarn drum. The fixed warp yarns 5 are used to replace the outermost warp yarns in existing air-jet looms to weave fabric. The fixed warp yarns 5 are positioned at the outermost side of all regular warp yarns 6. The two ends of the fixed warp yarns 5 are respectively fixedly connected to the warp guide shaft 7 and the waste yarn tension plate 3. The fixed warp yarns 5 are preferably made of nylon yarn.

[0021] Based on this, since the utility model adopts a fixed warp yarn 5 as the outermost warp yarn at the waste yarn position, it can not only reduce the total amount of waste yarn that cannot be reused, but also reuse the fixed warp yarn 5 to replace part of the original waste yarn and cooperate with the weft yarn to carry out the weaving operation of the edge of the cloth, thereby reducing the use of warp yarn and the amount of waste yarn generated, and effectively solving the problem of waste yarn in the weaving process of the existing air-jet loom, thereby greatly improving the gross profit margin of textile manufacturers. For example, based on the calculation of 0.0516 grams of waste yarn per yard of cloth, according to the number of plain fabrics unloaded in a single month, it can save 103.27 kilograms of waste yarn, thus achieving remarkable results.
