Description

Technical Field

[0001] This utility model relates to the field of compact spinning technology in textile machinery, and in particular to a novel gravity-tensioned compact spinning aggregation component. Background Technology

[0002] The fiber gathering component is a key part of the spinning device used to gather fiber slivers. It is a crucial component on the ring spinning machine, added after the fiber sliver is drafted and before twisting, to enhance the gathering process. After the fiber sliver is output from the front roller nip, it passes through the mesh ring on the negative pressure tube. The sliver moves on the mesh ring, and due to the contraction and aggregation of the airflow, the sliver gathers and rotates, gradually transforming from a flat state into a cylinder. The ends of the fibers are twisted into the yarn. This allows the fiber bundle to be tightened, straightened, and gathered during the conveying process before twisting during spinning, changing the shape of the fibers before yarn formation, effectively improving yarn evenness, reducing hairiness and fiber loss, and thus fundamentally improving the quality of the yarn.

[0003] A search revealed Chinese Patent Publication No. CN222455364U, which discloses a high-efficiency compact spinning negative pressure tube integral aggregation component, relating to the field of compact spinning negative pressure tube technology. The component includes a roller; both ends of the roller are fitted with an end assembly; the end assembly includes an end cap; one side of the end cap has a stepped hole for easy roller installation; a first mounting head and a second mounting head are respectively provided at both ends of the stepped hole; the first mounting head and the second mounting head are located on the same side; the first mounting head is fitted with the negative pressure tube; the first mounting head is inserted into the cavities at both ends of the negative pressure tube; a connecting rod is installed in the groove inside the second mounting head; during installation… The two end caps are effectively fitted to the ends of the rollers and the negative pressure tube and connecting rod. The first mounting head is inserted into the end cavity of the negative pressure tube, and the connecting rod is disassembled into the slot of the second mounting head to achieve effective fixed installation. The end of the roller is effectively fitted to the stepped hole through the bearing. However, the tension of the mesh ring is mainly achieved by the supporting force of the elastic torsion spring. After the spring steel wire is formed, it needs to be heat-treated, which is a complex process with high processing costs. The angle consistency of the torsion spring is poor, resulting in insufficient and inconsistent tension. The use of a torsion spring on one side leads to uneven tension on both sides of the tension plate, which causes the mesh ring to deviate. Once the mesh ring deviates, it will seriously affect the spinning performance. Moreover, the elasticity decays significantly during spinning, making it difficult to replace, resulting in high maintenance costs and hindering the continuous operation of spinning. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel gravity-tensioned tightly woven aggregate component, which aims to improve the problem of mesh rings easily deviating due to inconsistent tension and easy attenuation in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel gravity-tensioned compact spinning and gathering component, comprising a small roller, a negative pressure tube provided on the rear side of the outer wall of the small roller, a tension rod provided on the front side of the outer wall of the small roller, a plurality of limiting blocks equidistantly connected to the outer wall of the tension rod, a plurality of mesh rings equidistantly sleeved on the outer wall of the negative pressure tube, a counterweight sleeve assembly mechanism installed on the outer wall of the tension rod for counterweighting, and a fixing mechanism installed on the outer wall of the small roller for fixing; The counterweight assembly includes a cylindrical shaft, which is slidably connected to the outer wall of the tension rod. A stepped shaft is fixedly connected to the middle of the outer wall of the cylindrical shaft. Stepped shaft surfaces are fixedly connected to the left and right sides of the outer wall of the cylindrical shaft. An oblong groove is opened on the outer wall of the cylindrical shaft. The tension rod is disposed inside the oblong groove. The mesh ring is fitted on the outer wall of the cylindrical shaft.

[0006] As a further description of the above technical solution: The fixing mechanism includes a fixing seat, which is disposed on the left and right sides of the outer wall of the small roller. Each of the two fixing seats has an elongated slot on an adjacent side of its outer wall. The left and right ends of the tension rod are disposed on the inner walls of the two elongated slots. Each of the two fixing seats has a slot one on an adjacent side of its outer wall. The left and right ends of the negative pressure tube are installed on the inner walls of the two slots one. Each of the two fixing seats has a slot two on an adjacent side of its outer wall. The left and right ends of the small roller are installed on the inner walls of the two slots two.

[0007] As a further description of the above technical solution: Multiple cylindrical shafts are disposed on the left and right sides of the outer wall of the limiting block.

[0008] As a further description of the above technical solution: The tension bar has a long, narrow cross-section.

[0009] As a further description of the above technical solution: The mesh ring is fitted onto the outer wall of the small roller.

[0010] As a further description of the above technical solution: The tension bar is slidably connected to the elongated slot.

[0011] As a further description of the above technical solution: There is a certain gap between the tension rod and the waist-shaped slot.

[0012] As a further description of the above technical solution: The counterweight assembly mechanism can be a single spindle or a group of multiple spindles.

[0013] This utility model has the following beneficial effects: In this invention, the tension of the mesh ring is adjusted by adjusting the weight of the counterweight assembly mechanism. Simultaneously, a gap exists between the cylindrical shaft and the tension rod, which can adjust the tension differences caused by uneven circumference during mesh ring production, ensuring consistent tension for each mesh ring. This makes it suitable for different yarn types, and the mesh ring tension does not decrease, solving the problem of mesh ring misalignment. It also increases the angle between the mesh ring and the negative pressure pipe, preventing cotton lint and fly waste from accumulating, extending the sweeping cycle of compact spinning, and reducing maintenance costs for textile enterprises and the labor intensity of machine operators.

A stepped shaft 402 is fixedly connected to the middle of the outer wall of the cylindrical shaft 401. Stepped shaft surfaces 403 are fixedly connected to the left and right sides of the outer wall of the cylindrical shaft 401. An oblong slot 404 is opened on the outer wall of the cylindrical shaft 401. The tension rod 3 is set inside the oblong slot 404. The mesh ring 2 is sleeved on the outer wall of the cylindrical shaft 401. The fixing mechanism 6 includes a fixing seat 601, which is set on the left and right sides of the outer wall of the small roller 1. The two fixing seats 601 have an elongated slot 602 on the adjacent side of the outer wall. The left and right ends of the tension rod 3 are set on the inner wall of the two elongated slots 602. The two fixing seats 601 have a slot 1 603 on the adjacent side of the outer wall. The negative pressure pipe 7 is installed on the inner wall of the two slots 1 603. The two fixing seats 601 have a slot 2 604 on the adjacent side of the outer wall. The two small roller 1 is installed on the inner wall of the two slots 2 604. Multiple round shafts 401 are set on the left and right sides of the outer wall of the limiting block 5. The tension rod 3 is slidably connected to the elongated slot 602. Specifically, the mesh ring 2 is fitted around the small roller 1, the negative pressure tube 7, and the tension rod 3. The tension ring 2 is tensioned by the weight of the counterweight assembly mechanism 4. Multiple sets of limiting blocks 5 and multiple sets of counterweight assembly mechanisms 4 are installed on the tension rod 3. The limiting blocks 5 are installed on both sides of the cylindrical shaft 401. The counterweight assembly mechanism 4 can be made of metal or a combination of metal and other materials to position the cylindrical shaft 401. The limiting blocks 5 and the counterweight assembly mechanism 4 are evenly distributed, allowing for multiple spindles and different spindle spacings. The cylindrical shaft 401 has a waist-shaped slot 404 at its center that matches the shape of the tension rod 3. The middle part of 01 is designed as a stepped shaft 402 with a certain length and a diameter larger than that of the circular shaft 401. The length of the stepped shaft 402 is used to determine the spacing between adjacent mesh rings 2, that is, to set the spindle pitch. The two ends of the circular shaft 401 are respectively designed with stepped shaft surfaces 403. The stepped shaft 402 and the stepped shaft surfaces 403 ensure that the mesh ring 2 operates within the fixed position of the circular shaft 401 without deviation. The slots 603 and 604 of the fixed seat 601 fix the negative pressure pipe 7 and the small roller 1, respectively. The different weights of the counterweight sleeve combination mechanism 4 determine the different lengths of the mesh ring 2, and also determine the position of the tension rod 3 in the long slot 602. By adjusting the weight of the counterweight sleeve combination mechanism 4, the length adjustment of the mesh ring 2 can be met. The tension rod 3 moves in the long slot 602. There is a certain gap between the tension rod 3 and the waist-shaped slot 404 in the circular shaft 401, which has a certain self-adjusting function.

[0018] Reference Figure 1 , Figure 2 and Figure 3 The tension rod 3 has a long waist-shaped straight rod in cross section. The mesh ring 2 is fitted on the outer wall of the small roller 1. There is a certain gap between the tension rod 3 and the waist-shaped slot 404. The counterweight sleeve combination mechanism 4 can be a single spindle or a group of multiple spindles. Specifically, the elongated cross-section of the tension bar 3 can provide more suitable support and contact area. There is a certain gap between the tension bar 3 and the elongated slot 404, which has a certain self-adjusting effect and can adjust the tension difference caused by the uneven circumference of the mesh ring 2. The counterweight sleeve combination mechanism 4 can be designed as a single spindle or a group of multiple spindles as an integral design as needed.

[0019] Working principle: The mesh ring 2 is placed around the small roller 1, negative pressure tube 7, and tension rod 3. The weight of the counterweight sleeve assembly mechanism 4 provides tension to the mesh ring 2. Multiple sets of limiting blocks 5 and multiple sets of counterweight sleeve assembly mechanisms 4 are installed on the tension rod 3. The limiting blocks 5 are installed on both sides of the cylindrical shaft 401 to position the counterweight sleeve assembly mechanism 4. The counterweight sleeve assembly mechanism 4 can be designed as a single spindle or a single integrated design for multiple spindles as needed. The evenly distributed arrangement of the limiting blocks 5 and the cylindrical shaft 401 can realize the setting of multiple spindles and different spindle spacing. The center of the cylindrical shaft 401 is designed with an oblong slot 404 that matches the shape of the tension rod 3. The middle part of the cylindrical shaft 401 is designed as a stepped shaft 402 of a certain length with a diameter larger than the diameter of the cylindrical shaft 401. The length of the stepped shaft 402 determines the spacing between adjacent mesh rings 2, which is the setting of the spindle spacing. The two ends of the cylindrical shaft 401 are designed with stepped axial surfaces 403. The stepped shaft 402 and the stepped axial surfaces 403 confine the mesh ring 2 within the fixed position of the cylindrical shaft 401, preventing it from deviating. The slot 1 603 and slot 2 604 of the fixed seat 601 fix the negative pressure pipe 7 and the small roller 1, respectively. The different weights of the counterweight sleeve combination mechanism 4 determine the different lengths of the mesh ring 2, and at the same time determine the position of the tension rod 3 in the long strip slot 602. The length of the mesh ring 2 can be adjusted by adjusting the weight of the counterweight sleeve combination mechanism 4. The tension rod 3 moves in the long strip slot 602. There is a certain gap between the tension rod 3 and the waist-shaped slot 404 in the cylindrical shaft 401, which has a certain self-adjusting effect. It can adjust the tension difference caused by the uneven circumference of the mesh ring 2 and ensure that the tension of each mesh ring 2 is consistent.
