Description
Technical Field
[0001] This utility model relates to the technical field of polyester spinning equipment, specifically a yarn guiding device for a polyester yarn spinning machine. Background Technology
[0002] Polyester, as a synthetic fiber, is widely used in clothing, industrial fabrics, household goods and other fields due to its excellent properties such as high strength, good elasticity, wear resistance and corrosion resistance. In the spinning production process of polyester yarn, polyester fibers need to be processed into yarn and the yarn needs to be stably transported along a specific path to complete subsequent winding, twisting and other processes, and finally produce polyester yarn products that meet quality standards.
[0003] The existing technology has the following problems:
[0004] Existing technologies typically employ relatively simple guide rollers or guide rods. For yarn tension control, manual experience is required for periodic adjustments. Simple, fixed guide components cannot guide and support yarns with different orientations, necessitating frequent adjustments to the direction of the guide components. When equipment vibration or changes in yarn raw material characteristics occur during the spinning process, automatic adjustments cannot be made based on the dynamic changes in actual yarn tension, resulting in unstable yarn tension, affecting yarn strength and appearance quality, and reducing product yield.

A drive motor is provided at the bottom end of the drive screw. A vertical guiding component is provided between the two movable slides, and a horizontal guide roller is provided on the rear side of the top end of the support base.
[0010] Preferably, the horizontal guide roller includes two supporting shafts that are parallel to each other. A guide roller body is rotatably connected to the outer surface of the supporting shafts. Several anti-slip rubber strips that are parallel to each other are fixedly connected to the outer surface of the guide roller body. The anti-slip rubber strips are arranged alternately between two rows. The outer surface of the anti-slip rubber strips is in contact with the outer surface of the adjacent guide roller body.
[0011] Preferably, the vertical guide assembly includes a guide roller, with movable blocks fixedly connected to both ends of the guide roller. The outer surface of the left movable block is slidably connected to the inner side of the left movable groove, and the outer surface of the right movable block is slidably connected to the inner side of the right movable groove.

[0014] 2. This yarn guiding device for a polyester yarn spinning machine can adjust the position of the tension support roller in real time through a rotating seat, tension adaptation component, and support arm. When the yarn tension changes, the tension support roller drives the support arm to rotate around the rotating shaft, causing the adaptation spring to stretch or contract, thereby adjusting the yarn tension. It can quickly respond to various factors that cause tension changes, keeping the yarn at a stable tension. This avoids the negative impact of unstable tension on yarn strength and appearance quality, improves the product yield, and enhances the overall quality of polyester yarn.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a technical solution: a yarn guiding device for a polyester yarn spinning machine, including a support base 4, a support plate 3 is provided on the left and right sides of the top of the support base 4, an installation plate 1 is provided at the front end of the support plate 3, a multi-directional guiding mechanism 5 is provided on the opposite rear sides of the two support plates 3, and an automatic tension mechanism 2 is provided at the front left end of the right support plate 3.
[0023] During polyester yarn spinning, the yarn first contacts the automatic tension mechanism 2 on the right support plate 3. When the yarn tension changes, the automatic tension mechanism 2 can adjust the yarn tension in real time to ensure that the yarn tension is stable during subsequent transmission. Then the yarn enters the multi-directional guide mechanism 5, which enables the yarn to be transmitted stably along a specific path, completing the guiding work in the spinning machine and ensuring the smooth progress of the spinning process.
[0024] Please see Figure 2 The automatic tension mechanism 2 includes a rotating seat 21. The right end of the rotating seat 21 is fixedly connected to the left end of the right support plate 3. The left end of the rotating seat 21 is rotatably connected to a rotating shaft 22. A support arm 23 is fixedly connected to the outer surface of the rotating shaft 22. A connecting support shaft 24 is fixedly connected to the end of the support arm 23 away from the rotating shaft 22. A tension support roller 25 is rotatably connected to the left end of the connecting support shaft 24. Several guide grooves 26 are opened on the outer surface of the tension support roller 25. A tension adaptation component 27 is fixedly connected to the right end of the connecting support shaft 24.
[0025] If the yarn tension changes, it will act on the tension support roller 25. After the tension support roller 25 is subjected to force, it will drive the connecting support shaft 24 and then drive the support arm 23 to rotate around the rotation shaft 22 in coordination with the tension adaptation component 27. Through such rotation, the position of the tension support roller 25 is automatically adjusted. The guide groove 26 on the outer surface of the tension support roller 25 can keep the yarn in a stable direction, and finally realize the real-time adjustment of the yarn tension to ensure that the yarn maintains a stable tension state in subsequent transmission.
[0026] Please see Figure 2The tension adaptation component 27 includes a connecting column 273. The left end of the connecting column 273 is fixedly connected to the right end of the connecting support shaft 24. An adaptation spring 272 is rotatably connected to the outer surface of the connecting column 273. A support column 271 is rotatably connected to the end of the adaptation spring 272 away from the connecting column 273. The right end of the support column 271 is fixedly connected to the left end of the right support plate 3. The support column 271 is located directly above the rotating seat 21.
[0027] Once the yarn tension changes, the change is transmitted to the tension support roller 25. After being stressed, the connecting support shaft 24 drives the connecting column 273 to move. When the connecting column 273 moves, the adapting spring 272 will stretch or contract accordingly. If the yarn tension increases, the connecting column 273 drives the adapting spring 272 to stretch; if the yarn tension decreases, the adapting spring 272 contracts, thereby balancing the yarn tension and ensuring that the tension support roller 25 can maintain close contact with and guide the yarn, thus ensuring the spinning quality.
[0028] Please see Figure 3 The multi-directional guiding mechanism 5 includes two movable slides 51, which are respectively opened on the opposite rear sides of the two support plates 3. A drive screw 52 is provided inside the right movable slide 51. The top end of the drive screw 52 is rotatably connected to the top end of the inner side of the movable slide 51, and the bottom end of the drive screw 52 is rotatably connected to the bottom end of the inner side of the movable slide 51. A drive motor is provided at the bottom end of the drive screw 52. A vertical guide component 53 is provided between the two movable slides 51. A horizontal guide roller 54 is provided on the rear side of the top end of the support base 4.
[0029] After the drive motor starts, it drives the drive screw 52 to rotate. The rotation of the drive screw 52 causes the vertical guide component 53 to move up and down along the two moving slides 51. This can adjust the position of the vertical guide component 53 in the vertical direction, thereby guiding the yarn in the vertical direction. The horizontal guide roller 54 cooperates with the vertical guide component 53 to guide the yarn from both horizontal and vertical directions, so that the yarn can move accurately along the predetermined path during the transmission process, avoiding problems such as deviation and entanglement, and ensuring the smooth progress of the spinning process.
[0030] Please see Figure 4 The horizontal guide roller 54 includes two supporting rotating shafts 543, which are parallel to each other. A guide roller body 541 is rotatably connected to the outer surface of the supporting rotating shaft 543. Several anti-slip rubber strips 542 are fixedly connected to the outer surface of the guide roller body 541, which are parallel to each other. The two rows of anti-slip rubber strips 542 are arranged alternately, and the outer surface of the anti-slip rubber strips 542 is in contact with the outer surface of the adjacent guide roller body 541.
[0031] The parallel left and right support shafts 543 provide rotational support for the guide roller 541. When the yarn moves on the surface of the guide roller 541, the guide roller 541 rotates accordingly. The anti-slip rubber strip 542 increases the friction between the yarn and the guide roller, effectively preventing the yarn from shifting in the horizontal direction. At the same time, the anti-slip rubber strip 542 can make the two guide rollers 541 move synchronously through friction, ensuring the synchronicity of the conductor movement.
[0032] Please see Figure 5 The vertical guide assembly 53 includes a guide roller 533, with movable blocks 531 fixedly connected to both ends of the guide roller 533. The outer surface of the left movable block 531 is slidably connected to the inner side of the left movable groove 51, and the outer surface of the right movable block 531 is slidably connected to the inner side of the right movable groove 51. The inner side of the right movable block 531 is threadedly connected to the outer surface of the drive screw 52. Two parallel connecting blocks 534 are fixedly connected to the outer surface of the guide roller 533. A support frame 535 is fixedly connected to the rear side of both connecting blocks 534. The middle of the frame 535 can be guided by a horizontal guide roller 54. The middle of the rear end of the support frame 535 is fixedly connected to a regular hexagonal multi-directional guide disk 536. Each side of the multi-directional guide disk 536 is rotatably connected to a multi-directional guide wheel 537. The middle of the multi-directional guide disk 536 and the middle of the rear end of the support frame 535 are connected to a hexagonal wire passage 539. The middle of the multi-directional guide disk 536 is rotatably connected to a multi-directional guide wheel 538 on each side inside the wire passage 539. The middle of the outer surface of the guide roller 533 is rotatably connected to a horizontal guide wheel 532.
[0033] Driven by the drive screw 52, the guide roller 533 moves up and down along the moving groove 51 to adjust the vertical position of the yarn. When the yarn passes the horizontal guide wheel 532 on the outer surface of the guide roller 533, the horizontal guide wheel 532 provides initial vertical guidance for the yarn. Then the yarn enters the area of the multi-directional guide disc 536 supported by the connecting block 534 and the support frame 535, and passes through the yarn passage 539. During this process, the first multi-directional guide wheel 537 and the second multi-directional guide wheel 538 contact the yarn from different angles, providing support and guidance according to the direction of the yarn, ensuring accurate transmission of the yarn in the vertical direction, and avoiding vertical deviation or entanglement. Working together with the horizontal guide roller 54, it achieves precise multi-directional guidance of the yarn and ensures the stable operation of the spinning process.
[0034] Please see Figures 1-5During operation, the yarn begins to be transported, first passing through the automatic tension mechanism 2 at the front left end of the right support plate 3. When the yarn tension changes, the tension support roller 25 is forced to rotate the support arm 23 around the rotating shaft 22. Under the action of the tension adaptation component 27, the yarn tension is adjusted by stretching or contracting the adaptation spring 272. The yarn then enters the multi-directional guide mechanism 5. The anti-slip rubber strip 542 and the guide roller body 541 of the horizontal guide roller 54 perform horizontal positioning and guidance of the yarn. The horizontal guide wheel 532, the first multi-directional guide wheel 537, and the second multi-directional guide wheel 538 work together to vertically guide the yarn, ensuring that the yarn is stably transported along a specific path and completing the spinning guidance work.
