Description

Technical Field

[0001] This utility model relates to the textile field, specifically a polyester-cotton composite yarn drawing and winding device. Background Technology

[0002] Polyester-cotton composite yarn is a synthetic fiber made by blending polyester and cotton fibers. This type of fiber has good strength, abrasion resistance and comfort, and is widely used in clothing, home textiles and other fields. In the processing, the molten polyester and cotton fiber mixture needs to be stretched and wound into yarn by a winding device to facilitate subsequent processing.

[0003] Currently, during the processing, the positions of two stretching rollers need to be adjusted to meet different production requirements. However, if the distance between the two stretching rollers is too close during the adjustment process, friction may occur between them, which will accelerate the wear of the rollers. In addition, the excessively close distance may cause the fiber to be subjected to excessive compression and friction during the stretching process, resulting in reduced fiber strength and increased fuzz, thus reducing quality. Therefore, a polyester-cotton composite yarn stretching and winding device is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technology and avoid the problem of poor production results caused by adjusting the positions of the two stretching rollers too closely, this utility model proposes a polyester-cotton composite yarn stretching and winding device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a polyester-cotton composite yarn drawing and winding device, including a base plate, vertical plates are fixedly installed on the left and right sides of the top of the base plate, a stretching roller shaft is rotatably connected between the two vertical plates, the output shaft of a motor is fixedly connected to the left end of the stretching roller shaft, a protective component is provided between the two vertical plates, a winding rod is rotatably connected between the two vertical plates, and a motor is fixedly connected to the left end of the winding rod; The protective assembly includes vertical grooves formed at the top of the near ends of two vertical plates. A threaded rod is rotatably connected inside the vertical groove. Limiting grooves are formed on both the front and rear sides of the vertical groove. A slider is threadedly connected to the surface of the threaded rod. A second tension roller is rotatably connected to the end of the slider away from the vertical plate. A friction rod is slidably connected inside the slider. A top plate is fixedly connected to the top of the friction rod. A buffer spring is wound around the surface of the friction rod. An upper arc-shaped plate is fixedly connected to the bottom of the friction rod. A lower arc-shaped plate is fixedly connected to the lower side of the vertical plate. Guide blocks are fixedly connected to both the front and rear sides of the top of the slider. Limiting blocks are slidably connected inside the two guide blocks. A guide rod is slidably connected inside the near ends of the two limiting blocks. A pressure spring is fixedly connected between the two limiting blocks. A trapezoidal block is fixedly connected to the top of the limiting block. A second trapezoidal block is fixedly connected to the end of the top plate near the vertical plate.

[0006] Preferably, both motor one and motor two are fixedly installed on the left end face of the left vertical plate. The winding rod is located vertically between stretching roller shaft one and stretching roller shaft two. It can drive motor one to rotate stretching roller shaft one to perform hot pressing and stretching of polyester-cotton composite yarn, thereby improving the strength of polyester-cotton composite yarn. Motor two can drive the winding rod to rotate to wind the processed polyester-cotton composite yarn.

[0007] Preferably, the top end of the threaded rod passes through the top end of the vertical plate, and the slider is slidably connected inside the vertical groove. The operator can rotate the threaded rod to drive the slider to slide inside the vertical groove, thereby adjusting the distance between the second stretching roller shaft and the first stretching roller shaft.

[0008] Preferably, the top plate is located above the slider, the top end of the buffer spring is fixedly connected to the bottom end of the slider, and the bottom end of the buffer spring is fixedly connected to the top of the upper arc plate.

[0009] Preferably, the lowest end of the upper arc plate is located below the bottom of the second stretching roller shaft, the top of the lower arc plate is flush with the top of the first stretching roller shaft, and the bottom of the upper arc plate and the top of the lower arc plate are adapted to contact each other. When the second stretching roller shaft moves downward, the upper arc plate contacts the lower arc plate first. At this time, the position of the second stretching roller shaft is limited by the limiting block to prevent the second stretching roller shaft from continuing to move downward and contacting the first stretching roller shaft.

[0010] Preferably, the bottom of the limiting block is slidably connected to the top of the slider, and the limiting block is fitted into the inside of the limiting groove. The two trapezoidal blocks are located on opposite sides of the two trapezoidal blocks. After the limiting block is fitted into the inside of the limiting groove, the position of the slider is limited. Therefore, the position of the stretching roller shaft two, which is fixedly connected to the slider, is limited, preventing the stretching roller shaft two from continuing to move downward and affecting the processing of the polyester-cotton composite yarn.

[0011] Preferably, the adjacent ends of trapezoidal block one and trapezoidal block two are provided with inclined sides that are adapted to slide and connect. The trapezoidal block one and trapezoidal block two are adapted to slide and connect. When trapezoidal block two moves upward, the two trapezoidal blocks one will move along the inclined sides in a direction away from each other under the action of the pressure spring rebound force until the trapezoidal block one drives the limiting block to be locked inside the limiting groove.

[0012] The advantages of this utility model are: This invention allows for manual adjustment of the second stretching roller shaft to be closer to the first stretching roller shaft to meet different production needs. As the second stretching roller shaft gradually approaches the first stretching roller shaft, a limiting block engages inside the limiting groove, thereby limiting the position of the second stretching roller shaft. This prevents the second stretching roller shaft from continuing to move downwards and contacting the first stretching roller shaft, thus preventing the second stretching roller shaft from rotating relative to the first stretching roller shaft and accelerating wear. In addition, it prevents the polyester-cotton composite yarn from being excessively squeezed due to the close proximity of the second stretching roller shaft and the first stretching roller shaft, thereby improving the processing quality of the polyester-cotton composite yarn.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a drawing and winding device for polyester-cotton composite yarn. (Refer to...) Figure 1 A polyester-cotton composite yarn drawing and winding device includes a base plate 1, vertical plates 2 are fixedly installed on the left and right sides of the top of the base plate 1, a stretching roller shaft 31 is rotatably connected between the two vertical plates 2, the output shaft of a motor 32 is fixedly connected to the left end of the stretching roller shaft 31, a protective component 4 is provided between the two vertical plates 2, a winding rod 51 is rotatably connected between the two vertical plates 2, and a motor 52 is fixedly connected to the left end of the winding rod 51. Reference Figures 2-4The protective component 4 includes vertical grooves 41 formed at the top of the near ends of the two vertical plates 2. A threaded rod 42 is rotatably connected inside the vertical groove 41. Limiting grooves 43 are formed on both the front and rear sides of the vertical groove 41. A slider 441 is threadedly connected to the surface of the threaded rod 42. A second stretching roller shaft 442 is rotatably connected to the end of the slider 441 away from the vertical plate 2. Motor 32 and motor 52 are both fixedly installed on the left end face of the left vertical plate 2. The winding rod 51 is located vertically between the first stretching roller shaft 31 and the second stretching roller shaft 442. It can drive motor 32 to rotate the first stretching roller shaft 31 to perform hot pressing, shaping, and stretching of the polyester-cotton composite yarn, thereby improving the strength of the polyester-cotton composite yarn. Motor 52 can drive the winding rod 51 to rotate and wind the processed polyester-cotton composite yarn. The threaded rod 42... The top of the slide block 441 is slidably connected to the top of the vertical plate 2. The operator can rotate the threaded rod 42 to drive the slide block 441 to slide inside the vertical groove 41, thereby adjusting the distance between the second stretching roller shaft 442 and the first stretching roller shaft 31. A friction rod 451 is slidably connected inside the slide block 441. A top plate 452 is fixedly connected to the top of the friction rod 451. A buffer spring 453 is wound around the surface of the friction rod 451. An upper arc plate 454 is fixedly connected to the bottom of the friction rod 451. A lower arc plate 455 is fixedly connected to the lower side of the vertical plate 2. The top plate 452 is located above the slide block 441. The top of the buffer spring 453 is fixedly connected to the bottom of the slide block 441, and the bottom of the buffer spring 453 is fixedly connected to the top of the upper arc plate 454.

[0018] Reference Figures 4-5Guide blocks 461 are fixedly connected to both the front and rear sides of the top of slider 441. Limit blocks 462 are slidably connected inside both guide blocks 461. The lowest point of the upper arc plate 454 is located below the bottom of the second stretching roller shaft 442. The top of the lower arc plate 455 is flush with the top of the first stretching roller shaft 31. The bottom of the upper arc plate 454 and the top of the lower arc plate 455 are in contact. When the second stretching roller shaft 442 moves downward, the upper arc plate 454 contacts the lower arc plate 455 first. At this time, the position of the second stretching roller shaft 442 is limited by the limit blocks 462 to prevent it from continuing to move downward and contacting the first stretching roller shaft 31. Guide rods 463 are slidably connected inside the near ends of the two limit blocks 462. A pressure spring 464 is fixedly connected between the two limit blocks 462. A trapezoidal block 465 is fixedly connected to the top of the limit blocks 462. A trapezoidal block 465 is fixedly connected to the end of the top plate 452 near the vertical plate 2. The bottom of trapezoidal block 466 and limiting block 462 are slidably connected to the top of slider 441. Limiting block 462 is fitted and engaged inside limiting groove 43. The two trapezoidal blocks 466 are located on the opposite sides of the two trapezoidal blocks 465. After limiting block 462 is engaged inside limiting groove 43, the position of slider 441 is limited. Therefore, the position of stretching roller shaft 442, which is fixedly connected to slider 441, is limited, preventing stretching roller shaft 442 from continuing to move downward. The movement affects the processing of polyester-cotton composite yarn. Trapezoidal block 1 465 and trapezoidal block 2 466 are provided with matching sliding connected inclined sides at their near ends. Trapezoidal block 1 465 and trapezoidal block 2 466 are matched and slidably connected. When trapezoidal block 2 466 moves upward, the two trapezoidal blocks 1 465 will move along the inclined sides in a direction away from each other under the action of the rebound force of the pressure spring 464 until trapezoidal block 1 465 drives the limiting block 462 to be engaged inside the limiting groove 43.

[0019] Working principle: When the operator needs to adjust the distance between the second stretching roller shaft 442 and the first stretching roller shaft 31, the top of the threaded rod 42 is manually rotated. The threaded rod 42 will drive the threaded slider 441 to slide downward inside the vertical groove 41. At this time, the slider 441 will drive the second stretching roller shaft 442 to move downward, thereby reducing the distance between the second stretching roller shaft 442 and the first stretching roller shaft 31, so as to process polyester-cotton composite yarns with different production requirements. As slider 441 moves the second stretching roller shaft 442 downwards, it also moves the friction rod 451 downwards. Since the lowest point of the upper arc plate 454 is below the lowest point of the second stretching roller shaft 442, as the bottom of the second stretching roller shaft 442 gradually approaches the top of the first stretching roller shaft 31, the bottom of the upper arc plate 454 first contacts the lower arc plate 455, which is flush with the top of the first stretching roller shaft 31. Then, as the upper arc plate 454 continues to move downwards, it will contact the lower arc plate 455. Under the reaction force of 55, the compression buffer spring 453 is compressed, pushing the friction rod 451 and the top plate 452 upward. At this time, the top plate 452 will drive the fixedly connected trapezoidal block 466 to move upward as well. Before the trapezoidal block 466 moves upward, it abuts against the trapezoidal block 465 through the inclined surface that matches the trapezoidal block 465. At this time, the two trapezoidal blocks 465 are close to each other and the compression spring 464 is compressed. Therefore, during the process of the trapezoidal block 466 moving upward with the top plate 452, the trapezoidal block 466 is compressed. As trapezoidal block 465 and trapezoidal block 66 gradually separate, trapezoidal block 465 moves closer to trapezoidal block 466 under the rebound force of pressure spring 464, until trapezoidal block 465 moves until it is in contact with trapezoidal block 466 again. Then trapezoidal block 466 continues to move upward, while trapezoidal block 465 continues to move. When trapezoidal block 465 moves, it will drive the fixedly connected limiting block 462 to move into the limiting groove 43, until the limiting block 462 is pushed back by the rebound force of pressure spring 464. Under the action of the limit block 462, it abuts against the inner wall of the limiting groove 43. At this time, the position of the limit block 462 is limited by the friction between the limit block 462 and the inner wall of the limiting groove 43. That is, the limit block 462 and the slider 441 cannot continue to move downward. Therefore, the second stretching roller shaft 442, which is fixedly connected to the slider 441, cannot continue to move downward. At this time, the second stretching roller shaft 442 will not move downward and contact the first stretching roller shaft 31, thus avoiding the mutual wear of the second stretching roller shaft 442 and the first stretching roller shaft 31 and the reduction of the processing quality of the ground composite yarn during subsequent processing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
