Description

Technical Field

[0001] This utility model relates to acrylic yarn forming, and more particularly to an acrylic yarn forming device with adjustable tension. Background Technology

[0002] Acrylic yarn, as an important synthetic fiber, is widely used in the textile and apparel industries. In the textile production process, yarn formation and winding are crucial steps, directly affecting yarn quality and production efficiency. Traditional acrylic yarn forming devices mostly employ mechanical fixed take-up devices, manually adjusting winding speed and tension to ensure yarn uniformity and stability. However, this method suffers from drawbacks such as cumbersome operation, low precision of manual adjustment, and inability to guarantee uniform yarn winding.

[0003] For example, Chinese utility model patent application number 202322175054.9 discloses a device for bundling acrylic yarn, including a worktable. One end of the upper surface of the worktable is provided with a feeding wheel. A support frame is fixedly connected to the upper surface of the worktable. A traction block is provided on the upper surface of the worktable. A fixing frame is fixedly connected to the middle of the upper surface of the worktable. A base is fixedly connected to the top of the fixing frame. Limiting holes are equidistantly opened on the side of the base. A first motor is fixedly connected to the surface of the base near the traction block. In this utility model, through the support frame and the traction block, when using the device, the movable end of the thin yarn passes through the limiting ring at the top of the support frame and the traction hole on the surface of the traction block, and finally passes through the inside of the limiting hole and connects to the inner wall of the through hole. Through the provided support frame and traction block, the thin yarn can be tractioned and limited, which can prevent the thin yarn from tangling and knotting, and is conducive to improving the product quality of the device.

[0004] Although the aforementioned patent can achieve the bundling and forming of acrylic yarn, in actual use, due to the lack of lateral displacement compensation when the take-up roller rotates in one direction, the yarn is prone to stacking and tangling in local areas of the roller surface, requiring frequent machine stops to adjust the yarn bundle distribution. In addition, some existing forming devices lack tension control and are difficult to adapt to the high elasticity of acrylic fibers, which can easily lead to loose yarn or yarn breakage.

[0005] Therefore, those skilled in the art have proposed a tension-adjustable acrylic yarn forming device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tension-adjustable acrylic yarn forming device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tension-adjustable acrylic yarn forming device, comprising a worktable, a pay-off frame, several guide frames, several tension adjusting frames, and a yarn collecting frame fixedly connected to the top of the worktable; a pay-off assembly is provided on the inner wall of the pay-off frame; a guide assembly is provided on the top of the guide frame; sliding grooves are provided on both sides of the inner wall of the tension adjusting frame; an adjusting frame is slidably connected inside the two sliding grooves; a driving assembly is provided on the top of the adjusting frame; two adapting components are provided on the top and bottom surfaces inside the adjusting frame; an adapting shaft is provided at one end of the two adapting components; an adjusting wheel is rotatably connected to the outer wall of the adapting shaft; a yarn collecting drum is rotatably connected inside the yarn collecting frame; a yarn collecting assembly is provided on one side of the yarn collecting frame; two tripods are fixedly installed on the top of the worktable; a reciprocating screw and a take-up roller are rotatably connected between the opposite sides of the two tripods; and a take-up assembly is provided on one side of one of the tripods.

[0008] The pay-off frame is used to fix the pay-off assembly and provide support for the yarn. The pay-off assembly is installed on the inner wall of the pay-off frame to ensure that the yarn is smoothly drawn out from the yarn roll. The reciprocating screw rotates synchronously with the take-up roller through a belt pulley drive. Its function is to enable the yarn to move back and forth as it passes through the take-up roller, thereby avoiding uneven winding of the yarn. The reciprocating motion ensures that the yarn is evenly wound on the take-up roller, avoiding local over-tightness or under-tightness. The tripod is used to support the reciprocating screw and the take-up roller and provide them with rotational support. Two tripods are connected to each other to provide a stable support structure for the reciprocating screw and the take-up roller. The yarn collector is used to support the yarn collector drum. The yarn collector is connected to a servo motor to control the rotation of the yarn collector drum, ensuring that the yarn winding process proceeds smoothly.

[0009] As a further description of the above technical solution:

[0010] The wire feeding assembly includes several wire feeding rollers rotatably mounted on the inner wall of the wire feeding frame, and fine wire is wound around the outer wall of the wire feeding rollers.

[0011] The pay-off assembly includes multiple pay-off rollers mounted on the inner wall of the pay-off frame. These rollers guide the yarn from the outer thread and maintain appropriate tension, thereby preventing the yarn from tangling or clogging.

[0012] As a further description of the above technical solution:

[0013] The guide assembly includes a guide seat fixedly installed on the top of the guide frame, and the guide seat has a guide hole inside.

[0014] The guide frame is used to support the guide assembly. The guide holes opened on the guide seat can effectively guide the direction of the yarn, ensuring that the yarn does not deviate from the predetermined path and avoiding tangling or breakage during the yarn forming process.

[0015] As a further description of the above technical solution:

[0016] The drive assembly includes a threaded rod rotatably connected to the top of the adjustment frame, the top of which extends through to the outside of the tension adjustment frame and is fixedly connected to a drive wheel.

[0017] The outer wall of the threaded rod is threadedly connected to the tension adjustment frame. By rotating the drive wheel, the threaded rod drives the adjustment frame to move up and down, thereby adjusting the tension. By adjusting the tension, the tension of the yarn can be controlled precisely and stably.

[0018] As a further description of the above technical solution:

[0019] The adaptation component includes a telescopic rod and a spring. The telescopic rod is fixedly installed on the top and bottom of the inner wall of the adjustment frame, and the spring is sleeved on the outer wall of the telescopic rod. One end of the two telescopic rods is fixedly connected to the outer wall of the adaptation shaft.

[0020] The adaptive component, through the cooperation of a telescopic rod and a spring, helps to automatically adapt to changes in yarn tension. When the yarn tension fluctuates, the spring rebounds and adjusts the position of the adjusting wheel via the telescopic rod, ensuring that the yarn tension remains stable and avoiding yarn damage or quality problems caused by excessive or insufficient tension.

[0021] As a further description of the above technical solution:

[0022] The hub assembly includes a servo motor fixedly mounted on the outer wall of the hub frame via a support plate. The output end of the servo motor is fixedly connected to a gear, and the outer wall of the gear is meshed with an external gear ring.

[0023] One side of the external toothed ring is fixedly connected to one side of the yarn drum. The servo motor can precisely control the rotation speed of the yarn drum, ensuring that the yarn is evenly wound on the yarn drum and avoiding unevenness or tightness during the winding process.

[0024] As a further description of the above technical solution:

[0025] A traction frame is fixedly installed on one side of the hub and on the side of the hub drum.

[0026] The traction frame fixes the inlet position of the cable drum and constrains the direction of cable movement.

[0027] As a further description of the above technical solution:

[0028] The winding assembly includes a drive motor and two pulleys. The drive motor is fixedly mounted on one side of one of the tripods via a support plate. The two pulleys are respectively fixedly mounted on one end of the reciprocating lead screw and the take-up roller. The two pulleys are connected by a belt drive. The output end of the drive motor is rotatably connected to one of the pulleys. The outer wall of the reciprocating lead screw is threaded with a take-up seat. The bottom of the take-up seat is slidably connected to a limiting rod via a sleeve.

[0029] The two ends of the limiting rod are fixedly connected to the opposite side of the two tripods. The reciprocating screw and take-up roller are driven to rotate by the drive motor and pulley, ensuring that the yarn is smoothly wound on the take-up roller. The cooperation between the take-up seat and the limiting rod allows the take-up roller to evenly tighten the yarn during the winding process, avoiding uneven winding.

[0030] This utility model has the following beneficial effects:

[0031] 1. Compared with the prior art, this tension-adjustable acrylic yarn forming device, through the coordinated use of structures such as a chute, adjusting wheel, drive assembly, and adaptation assembly, can adjust the rotation of the threaded rod by rotating the drive wheel, thereby driving the adjusting wheel to move up and down, thus achieving precise control of yarn tension. At the same time, with the rebound effect of the spring, the adjusting wheel can automatically adapt to the tension changes of the yarn, ensuring uniform tension distribution and avoiding the risk of yarn breakage due to excessive tension.

[0032] 2. Compared with existing technologies, this tension-adjustable acrylic yarn forming device, through the coordinated use of structures such as a tripod, reciprocating screw, take-up roller, and take-up assembly, can ensure that the yarn is evenly distributed during the winding process by driving the take-up block to move back and forth using the reciprocating screw. This avoids the problem of the yarn being heavily entangled in a certain part, and can automatically adjust the winding position of the yarn to ensure uniform winding of the yarn on the take-up roller. This reduces the trouble of manual intervention and improves production efficiency and yarn winding quality. Attached Figure Description

An adapting shaft 8 is provided at one end of each of the two adapting components. An adjusting wheel 9 is rotatably connected to the outer wall of the shaft 8. A yarn collecting drum 10 is rotatably connected inside the yarn collecting frame 5. A yarn collecting assembly is provided on one side of the yarn collecting frame 5. Two tripods 11 are fixedly installed on the top of the workbench 1. A reciprocating screw 12 and a take-up roller 13 are rotatably connected between the opposite sides of the two tripods 11. A take-up assembly is provided on one side of one of the tripods 11. The pay-off frame 2 is used to fix the pay-off assembly and provide pay-off support for the yarn. The pay-off assembly is provided on the inner wall of the pay-off frame 2 to ensure that the yarn is smoothly drawn out from the yarn roll. The reciprocating screw 12 rotates synchronously with the take-up roller 13 through the belt pulley 27. Its function is to enable the yarn to reciprocate as it passes through the take-up roller 13, thereby avoiding uneven winding of the yarn. The reciprocating motion ensures that the yarn is evenly wound on the take-up roller 13, avoiding local over-tightness or over-looseness. The tripod 11 is used to support the reciprocating lead screw 12 and the take-up roller 13 and to provide them with rotational support. The two tripods 11 are connected to each other to provide a stable support structure for the reciprocating lead screw 12 and the take-up roller 13. The yarn collector 5 is used to support the yarn collector 10. The yarn collector 5 controls the rotation of the yarn collector 10 through the connection with the servo motor 22 to ensure that the yarn winding process proceeds smoothly. Through the cooperation of the slide 6, adjusting wheel 9, drive assembly and adaptation assembly, the rotation of the threaded rod 18 can be adjusted by rotating the drive wheel 19, thereby driving the adjusting wheel 9 to move up and down, thereby achieving precise control of the yarn tension. At the same time, with the rebound action of the spring 21, the adjusting wheel 9 can automatically adapt to the tension changes of the yarn, ensuring uniform tension distribution and avoiding the risk of yarn breakage due to excessive tension.

[0042] The pay-off assembly includes several pay-off rollers 14 rotatably mounted on the inner wall of the pay-off frame 2. Fine threads 15 are wound around the outer wall of the pay-off rollers 14. The pay-off assembly includes multiple pay-off rollers 14, which are mounted on the inner wall of the pay-off frame 2. Their function is to guide the yarn from the outer fine threads 15 and maintain appropriate tension, thereby avoiding yarn entanglement or blockage. The guide assembly includes a guide seat 16 fixedly mounted on the top of the guide frame 3. The guide seat 16 has a guide hole 17 inside. The guide frame 3 is used to support the guide assembly. The guide hole 17 on the guide seat 16 can effectively guide the direction of the yarn, ensuring that the yarn does not deviate from the predetermined path and avoiding tangling or breakage during the yarn forming process.

[0043] The drive assembly includes a threaded rod 18 rotatably connected to the top of the adjustment frame 7. The top of the threaded rod 18 extends through to the outside of the tension adjustment frame 4 and is fixedly connected to a drive wheel 19. The outer wall of the threaded rod 18 is threadedly connected to the tension adjustment frame 4. By rotating the drive wheel 19, the threaded rod 18 drives the adjustment frame 7 to move up and down, thereby realizing the adjustment of tension. By adjusting the tension, the tension of the yarn can be precisely and stably controlled.

[0044] The adaptation component includes a telescopic rod 20 and a spring 21. The telescopic rod 20 is fixedly installed on the top and bottom of the inner wall of the adjustment frame 7, and the spring 21 is sleeved on the outer wall of the telescopic rod 20. One end of the two telescopic rods 20 is fixedly connected to the outer wall of the adaptation shaft 8. Through the cooperation of the telescopic rod 20 and the spring 21, the adaptation component helps to automatically adapt to changes in yarn tension. When the yarn tension fluctuates, the spring 21 rebounds and adjusts the position of the adjustment wheel 9 through the telescopic rod 20 to ensure that the yarn tension remains stable and to avoid yarn damage or quality problems caused by excessive or insufficient tension.

[0045] The yarn gathering assembly includes a servo motor 22 fixedly mounted on the outer wall of the yarn gathering frame 5 via a support plate. A gear 23 is fixedly connected to the output end of the servo motor 22. An external gear ring 24 is meshed with the outer wall of the gear 23. One side of the external gear ring 24 is fixedly connected to one side of the yarn gathering drum 10. The drive of the servo motor 22 can precisely control the rotation speed of the yarn gathering drum 10, ensuring that the yarn is evenly wound on the yarn gathering drum 10 and avoiding unevenness or tightness problems during the winding process.

[0046] A traction frame 25 is fixedly installed on one side of the cable tray 5 and on the other side of the cable drum 10. The traction frame 25 fixes the inlet position of the cable drum 10 and constrains the movement direction of the thin wire 15.

[0047] The take-up assembly includes a drive motor 26 and two pulleys 27. The drive motor 26 is fixedly mounted on one side of one of the tripods 11 via a support plate. The two pulleys 27 are respectively fixedly mounted on one end of the reciprocating screw 12 and the take-up roller 13. The two pulleys 27 are connected by a belt drive. The output end of the drive motor 26 is rotatably connected to one of the pulleys 27. The outer wall of the reciprocating screw 12 is threadedly connected to a take-up seat 28. The bottom of the take-up seat 28 is slidably connected to a limiting rod 29 via a sleeve. The two ends of the limiting rod 29 are fixedly connected to the opposite side of the two tripods 11. The drive motor 26 and the pulleys 27 drive the reciprocating screw 12 and the take-up roller 13 to rotate, ensuring that the yarn is smoothly wound on the take-up roller 13. The cooperation between the take-up seat 28 and the limiting rod 29 enables the take-up roller 13 to evenly tighten the yarn during the winding process, avoiding uneven winding.

[0048] Working principle: First, place the acrylic yarn 15 on the pay-off roller 14. Then, pass the yarn 15 through the guide hole 17, and then pass the yarn 15 through any hole on the traction frame 25. Next, pass the yarn 15 through the position between the two adjusting wheels 9 on the tension adjusting frame 4, and then through the hole on the yarn collector 10 corresponding to the traction frame 25. Then, start the servo motor 22, which rotates its output end to drive the gear 23 to rotate, causing the meshing external gear ring 24 to rotate, which in turn rotates the yarn collector 10, causing the yarn 15 to wind together. The resulting yarn passes through the hole at the top of the take-up seat 28, and then... The yarn is wound around the take-up roller 13 and fixed. At this time, the drive motor 26 can be started, and its output end rotates to drive one of the pulleys 27 to rotate. Under the action of the belt, the reciprocating screw 12 and the pay-off roller 14 rotate synchronously. As a result, the yarn passing through the take-up seat 28 will move back and forth under the action of the reciprocating screw 12, so that the yarn can be evenly wound on the take-up roller 13 after forming. This avoids the phenomenon that the yarn is wrapped in a large amount in a certain part during the winding process. This structure can automatically adjust the winding position of the yarn, improve the winding uniformity, reduce the trouble of manual intervention, and improve production efficiency.

[0049] During the winding process, when it is necessary to adjust the tension during the forming process, the drive wheel 19 can be rotated, causing the threaded rod 18 to rotate. This allows the adjusting frame 7 to move up and down along the slide groove 6 on the tension adjusting frame 4 under the action of the threaded rod 18, thereby synchronously driving the adjusting wheel 9 to move, thus adjusting the tension of the processed fine thread 15. At the same time, when the adjusting wheel 9 adjusts the tension of the fine thread 15, the adapting shaft 8 located on the adjusting wheel 9 will rebound under the action of the spring 21. During the rebound deformation of the spring 21, the telescopic rod 20 inside it plays a guiding and supporting role. At this time, the rebound of the spring 21 allows the adjusting wheel 9 to automatically adapt to the changes in the thread bundle, ensuring uniform tension distribution and avoiding the problem of yarn breakage due to excessive tension, making the entire system more stable and efficient.

[0050] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
