Description

Technical Field

[0001] This utility model relates to the field of air-jet looms, and more particularly to a shedding mechanism for a denim air-jet loom. Background Technology

[0002] An air-jet loom is a weaving device that uses high-speed airflow to feed the weft yarn into the warp yarn. It is characterized by high speed and high efficiency. Its working principle is that the airflow generated by the nozzle pushes the weft yarn through the warp yarn to form a fabric. The advantages of air-jet looms include high production efficiency, stable fabric quality, and strong adaptability. It can weave a variety of fabrics, such as cotton, chemical fiber, and wool. Compared with traditional shuttle looms, air-jet looms have higher production speed and lower noise, and are an important piece of equipment widely used in modern weaving industry.

[0003] The shedding mechanism of an air-jet loom is mainly used to separate the warp yarns so that the weft yarns can pass through smoothly. Shedding methods of air-jet looms include crank shedding, cam shedding, and multi-arm shedding. Crank shedding is driven by a crank mechanism and is suitable for the production of most fabrics. Cam shedding achieves shedding through the rotation of a cam, which has high precision and stability. Multi-arm shedding uses multiple shedding arms working together and is suitable for the production of complex fabrics. As for weft insertion methods, there are rapier weft insertion, air-jet weft insertion, water-jet weft insertion, and shuttle weft insertion. Rapier weft insertion is suitable for high-speed and high-density fabrics. Air-jet and water-jet weft insertion are suitable for the efficient production of thin and soft fabrics, while shuttle weft insertion is often used to weave medium-density fabrics and has high weaving flexibility. The choice of various shedding and weft insertion methods depends on the requirements of the fabric and the working performance of the loom.

[0004] With the rapid development of the times and the ever-changing lives of people, the requirements for the quality and color of denim fabrics are getting higher and higher, and the weave of denim fabrics is becoming more and more diverse. However, the eight-heal frame cam shedding weave of traditional air-jet looms is relatively simple and cannot meet the production needs of the market, which is a strong limitation. Therefore, a shedding mechanism for denim air-jet looms is proposed to solve the above problems. Utility Model Content

The collection frame can be quickly removed, making it convenient to process the impurities inside the collection frame. Attached Figure Description

[0035] Working Principle: When weaving on the main body 1 of the air-jet loom, the rotation of the conjugate cam 3 actuates the rotor swing arm 4, which in turn drives the connecting rod 5 to pull the lever 6, causing the push-pull rod 7 to drive the angled rod 8 to reciprocate and deflect the top vertical rod 9. This, in turn, causes the heddle frames 10 to move up and down rapidly, increasing the number of heddle frames from 8 to 10. This increases the number of heddle frames 10 on the main body 1 of the air-jet loom, allowing for a wider variety of denim fabric patterns and enabling the weaving of more complex patterns. When producing twill, satin, or small jacquard fabrics, increasing the number of heddle frames 10 allows for independent control of multiple warp yarns, providing more style options for orders and adapting to special process requirements. Multiple heddle frames 10 can be used for layered weaving, such as double-layer fabric, shortening the weaving cycle and improving production efficiency. During production, some lint and debris are generated; these are addressed by the fan 13 providing suction to the air intake 14. The air intake 14 draws the lint generated by the main body 1 of the air-jet loom into the collection frame 12 for collection, preventing the lint from affecting the surrounding environment. After production is completed, the lint collected in the collection frame 12 needs to be processed. By moving the lever 18, the slide plate 17 is driven to compress the spring 16, causing the insertion rod 19 to retract into the outer shell 15 and disengage from the collection frame 12. At the same time, the stop bar 20 will automatically fall down to block the outlet of the insertion rod 19. At this time, the collection frame 12 is unlocked. Then, the collection frame 12 is pulled out from the sleeve 11 and the lint inside is removed. The collection frame 12 is then reinserted into the sleeve 11. Next, the lever 21 is pulled up to disengage the stop bar 20 from the insertion rod 19. At this time, the spring 16 will instantly push the slide plate 17 to reset, causing the insertion rod 19 to pop out and insert into the collection frame 12, fixing the collection frame 12 in the sleeve 11, thus completing the cleaning. The operation is convenient and labor-saving.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
