Description

Technical Field

[0001] The invention relates to the technical field of spinning, in particular to a health-care AB yarn production device and a production method. Background Art

[0002] As the times continue to advance, people's requirements for clothing fabrics continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversity and high quality. Therefore, new requirements have been put forward for the development of textile raw materials. Various new types of fibers are constantly being developed and applied to textile processing. Drafting is a key link in spinning processing, which involves the drawing process, roving process, and spun spinning process in the spinning process. The change of the yarn structure processed by the change of drafting is an important way to develop multiple varieties in spinning, such as fancy yarn, AB yarn, etc.

[0003] AB yarn is a kind of spun yarn made by siro spinning technology, usually mixed from two different raw materials. This yarn is sometimes also called AB colored yarn or AB plied yarn. In the process of AB yarn formation, two rovings of different raw materials are spun into a spun yarn through siro spinning technology. Siro spinning technology is to feed two slivers with a certain distance into the spun yarn drafting area, and then draft them separately and twist them into yarn. This technology makes the fibers on the surface of the yarn arranged neatly, the structure is compact, the hairiness is small, and the anti-pilling performance is good. Therefore, in the production of AB yarn, two different roving raw materials are involved. Due to the difference in the fiber raw materials in the two rovings, the two rovings should adopt a corresponding drafting process configuration during the drafting process. However, in the current AB yarn production, both roving raw materials use the same drafting configuration, which affects the quality of the yarn. Summary of the invention

[0031] The second servo motor 25 drives the roller shaft 6 of the middle and lower roller 4 to rotate, and then drives the roller sleeve 7 of the middle and lower roller 4 that is integrally fixedly connected thereto to rotate, and then drives the lower long leather ring 23 that is inserted into the sleeve to rotate synchronously, and then drives the upper short leather ring 22 that is in close pressing contact with it to rotate, and then drives the middle pressing rubber roller 21 of the middle and lower roller 4 to rotate synchronously, thereby transforming the middle holding jaw into the middle holding continuous conveying jaw, transforming the leather ring pressing control surface into the leather ring pressing continuous conveying control surface, and transforming the elastic output jaw into the elastic continuous output jaw.

[0032] The third servo motor 26 drives the roller shaft 6 of the front lower roller 5 to rotate, and then drives the roller sleeve 7 of the front lower roller 5 which is integrally fixedly connected thereto to rotate. The roller sleeve 7 of the front lower roller 5 rotates and then drives the left pressing rubber roller 15 of the front lower roller 5 which is in close pressing contact with it to rotate, thereby transforming the left front holding jaw into the left front holding continuous conveying jaw. At the same time, the roller sleeve 7 of the front lower roller 5 rotates and then drives the right pressing rubber roller 14 of the front lower roller 5 which is in close pressing contact with it to rotate, thereby transforming the right front holding jaw into the right front holding continuous conveying jaw.

[0033] The left rear holding continuous conveying jaw, the middle holding continuous conveying jaw, and the left front holding continuous conveying jaw constitute the left stretching system, and the left rear stretching zone is formed between the left rear holding continuous conveying jaw and the middle holding continuous conveying jaw, and the right rear stretching zone is formed between the middle holding continuous conveying jaw and the left front holding continuous conveying jaw. The right rear holding continuous conveying jaw, the middle holding continuous conveying jaw, and the right front holding continuous conveying jaw constitute the right stretching system, and the right rear stretching zone is formed between the right rear holding continuous conveying jaw and the middle holding continuous conveying jaw, and the right front stretching zone is formed between the middle holding continuous conveying jaw and the right front holding continuous conveying jaw.

[0034] During spinning, the left rear holding and continuous conveying jaw is located at the rear side of the roller sleeve 7 of the rear lower roller 3, and the right rear holding and continuous conveying jaw is located at the front side of the roller sleeve 7 of the rear lower roller 3, so that the holding distance of the left rear stretching zone is greater than that of the right rear stretching zone. At the same time, the left front holding and continuous conveying jaw is located at the front side of the roller sleeve 7 of the front lower roller 5, and the right front holding and continuous conveying jaw is located directly above the roller sleeve 7 of the front lower roller 5, so that the holding distance of the left front stretching zone is greater than that of the right front stretching zone. The lyocell / soybean blended roving 2 with large average fiber length and high length uniformity is stretched by the left stretching system, and the combed cotton roving 1 with small average fiber length and low length uniformity is stretched by the right stretching system.

[0035] The fed lyocell / soybean blended roving 2 is held by the left rear holding continuous conveying jaw and then enters the drafting system. The fed lyocell / soybean blended roving 2 first passes through the upper circular surface of the roller sleeve 7 of the rear lower roller 3, thereby being supported by the rotating roller sleeve 7 of the rear lower roller 3 and driven and conveyed forward again, thereby realizing the forward extension of the holding, driving and conveying effect of the left rear holding continuous conveying jaw on the lyocell / soybean blended roving 2. The fed lyocell / soybean blended roving 2 is then held by the middle holding continuous conveying jaw and is stretched by the left rear drafting zone to produce a lyocell / soybean blended fiber bundle with reduced linear density. The lyocell / soybean blended fiber bundle then immediately enters the leather ring pressing and continuous conveying control surface, thereby being supported by the rotating leather ring pressing and continuous conveying control surface. The lyocell / soybean blended fiber bundle is output by the elastic continuous output jaw, and the output lyocell / soybean blended fiber bundle is output to the drafting system after being grasped by the left front grasping continuous conveying jaw, and is subjected to the drafting action of the left front drafting zone to obtain the lyocell / soybean blended strands with reduced linear density. During this process, the lyocell / soybean blended fiber bundle passes through the upper circular surface of the roller sleeve 7 of the front lower roller 5 and is then grasped by the left front grasping continuous conveying jaw, thereby being supported and driven forward by the rotating roller sleeve 7 of the front lower roller 5, thereby achieving the backward extension of the grasping and driving conveying action of the front grasping continuous conveying jaw on the lyocell / soybean blended fiber bundle.

[0036] The fed combed cotton roving 1 is held by the right rear holding continuous conveying jaw and then enters the drafting system. During this process, the combed cotton roving 1 first passes through the upper circular surface of the roller sleeve 7 of the rear lower roller 3, thereby being supported and driven forward by the rotating roller sleeve 7 of the rear lower roller 3, and then the holding, driving and conveying effect of the left rear holding continuous conveying jaw on the combed cotton roving 1 is extended backward. The fed combed cotton roving 1 is then held by the middle holding continuous conveying jaw and is drawn by the right rear drawing zone to produce a dense line. The combed cotton bundle with reduced density then immediately enters the leather ring pressing and continuous conveying control surface, thereby being supported and driven forward by the rotating leather ring pressing and continuous conveying control surface, and then the holding and driving conveying effect of the middle holding continuous conveying jaw on the combed cotton bundle is extended forward until the combed cotton bundle is output by the elastic continuous output jaw, and the output combed cotton bundle is directly held by the right front holding and continuous conveying jaw and then output to the drafting system, where it is stretched by the left front drafting zone to produce combed cotton slivers with reduced linear density.

[0037] The lyocell / soy blended sliver and combed cotton sliver output by the drafting system are twisted to obtain health-care AB yarn under the action of the twisting twist transmitted by the spinning frame twisting system, and the health-care AB yarn is wound on the spinning tube 31 in a clockwise or counterclockwise direction. In this process, the main motor drives all the spindles to rotate through the spindle belt, and then drives the spinning tube 31 to rotate. The rotation of the spinning tube 31 then drives the health-care AB yarn to pass through the yarn guide hook 28 and the wire ring 29 in turn and be wound on the spinning tube 31, so that the wire ring 29 rotates around the steel collar 30. At this time, due to the flexible structure of the health-care AB yarn and the weight of the wire ring 29 itself, the health-care AB yarn The winding speed of the B yarn on the spun yarn tube 31 is lower than the rotation speed of the spun yarn tube 31, and the speed difference between the two generates twisting twist, which is transmitted from bottom to top. When it is transmitted to the lower twisting point, it continues to be transmitted separately along the directions of the lyocell / soybean blended yarn and the combed cotton yarn, respectively, so that the lyocell / soybean blended yarn is twisted under the action of the transmitted first sub-twist to obtain the lyocell / soybean blended yarn, and the combed cotton yarn is twisted under the action of the transmitted second sub-twist to obtain the combed cotton yarn. The lyocell / soybean blended yarn and the combed cotton yarn are twisted together at the lower twisting point to obtain the final health-care AB yarn.
