Description
Technical Field
[0001] This application relates to the field of twisting machine technology, specifically a self-balancing yarn tension guiding device for a filament twisting machine. Background Technology
[0002] Twisting machines are core equipment in the textile industry, mainly used to apply twist to materials such as raw silk, staple yarn, and chemical fiber filaments to improve their physical properties and appearance.
[0003] An existing patent (publication number: CN216473653U) discloses a twisting machine that facilitates twist adjustment, including a support, a housing, a pay-off spool, a twister, and an adjustment assembly. The housing is fixed to the top of the support, and a motor is fixed to the bottom of the housing. A pair of yarn holes are provided on the inner sidewall of the top of the housing. A winding mechanism is provided at the output end of the motor. The pay-off spool is located on the top of the housing. The twister is fixed to the inner sidewall of the housing. The adjustment assembly is located inside the housing. The adjustment assembly includes a rectangular block, a slide rod, a yarn wheel, and an adjustment mechanism. The rectangular block is fixed to the inner sidewall of the housing, and a cavity is provided inside the rectangular block. The slide rod is slidably connected to the cavity by a spring. The yarn wheel is fixed to the sidewall of the slide rod. The adjustment mechanism is located on the sidewall of the housing and contacts the slide rod. The tension of the yarn is adjusted by the adjustment assembly, allowing the winding mechanism to perform winding work better.
[0004] The aforementioned equipment requires manual adjustment of the tension of the yarn wheel via a threaded rod during operation. It cannot automatically adjust when the yarn tension changes, thus failing to maintain a continuous tension balance during yarn winding. Furthermore, the yarn remains in the same position during winding, preventing it from being evenly wound on the spool and affecting the winding process and quality. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a self-balancing yarn tension guiding device for a filament twisting machine. This device automatically adjusts and balances yarn tension during the yarn winding process, guides the yarn during winding to ensure even winding onto the spool, and guarantees winding quality. It solves the problems of existing twisting machines failing to automatically adjust when yarn tension changes, thus failing to maintain continuous yarn tension balance during winding, and the yarn remaining in the same position on the spool during winding, resulting in uneven winding and affecting the winding operation and quality.
[0006] To achieve the above objectives, this application provides the following technical solution: a self-balancing yarn tension guiding device for a filament twisting machine, comprising a frame, a housing fixedly connected to the front of the frame, a slide rod slidably connected to the inside of the housing via a slide groove, a frame fixedly connected to one side of the slide rod, a tensioning wheel rotatably connected to the end of the frame away from the slide rod, a spring fixedly connected to the side of the slide rod inside the housing, the other end of the spring fixedly connected to the inner wall of the housing, a first motor fixedly connected to the back of the frame, a lead screw fixedly connected to the output end of the first motor, a first guide wheel threadedly connected to the outer circumferential surface of the lead screw, a second motor fixedly connected to the back of the frame, a rotating shaft fixedly connected to the output end of the second motor, a yarn spool slidably sleeved on the outer circumferential surface of the rotating shaft, and a second guide wheel rotatably connected to the top of the frame.
[0007] The above solution addresses the issue that existing twisting machines cannot automatically adjust to changes in yarn tension, thus failing to maintain tension balance during yarn winding. Furthermore, the yarn remains in the same position on the spool during winding, preventing even winding and impacting winding quality. By incorporating a housing, slide bar, frame, tension wheel, and spring, the solution automatically adjusts and balances yarn tension during winding, ensuring optimal tension and continuous yarn production. The rotation of the lead screw drives the first guide wheel laterally, guiding the yarn and ensuring even winding on the spool, thus guaranteeing winding quality.
[0008] Furthermore, the tensioning wheel, the first guide wheel, and the second guide wheel all have annular grooves inside, and the inside and edges of the annular grooves of the tensioning wheel, the first guide wheel, and the second guide wheel are all arc-shaped.
[0009] The above design, with its annular groove and curved interior and edges, effectively reduces the friction between the yarn and the wheel surfaces as it passes through each wheel, thus reducing yarn wear and ensuring yarn quality. The curved edges also prevent the yarn from getting stuck or snagged during turning, making yarn transport smoother and improving the stability and reliability of the yarn guiding process.
[0010] Furthermore, the slide bar has a rectangular structure, and the slot inside the outer shell is a rectangular slot adapted to the slide bar.
[0011] The above scheme prevents the slide bar from rotating during sliding, ensuring that the slide bar always maintains stable linear motion. This makes the position adjustment of the tension wheel more precise, ensuring that the tension wheel's adjustment of yarn tension is stable and reliable, thereby improving the working accuracy of the entire yarn tension guiding device.
[0012] Furthermore, a mounting bracket is fixedly connected to the top of the frame, and a twister is fixedly connected inside the mounting bracket.
[0013] The above solution ensures the stability of the twister installation, allowing the twister to complete the yarn twisting operation.
[0014] Furthermore, a limiting block is fixedly connected to the upper surface of the slide rod, a limiting hole is opened inside the outer shell, and the outer surface of the limiting block is slidably connected to the outer shell through the limiting hole.
[0015] The above scheme effectively limits the sliding stroke of the slide bar, preventing it from exceeding the safe range during sliding and avoiding abnormal position of the tension wheel due to excessive sliding of the slide bar. This ensures that the tension wheel's adjustment of yarn tension is always within a reasonable range, improving the safety and stability of the device.
[0016] Furthermore, a first positioning ring is fixedly sleeved on the outer circumferential surface of the rotating shaft, and a second positioning ring is threadedly connected to the outer circumferential surface of the rotating shaft through a threaded structure.
[0017] The above method allows the cable reel to be installed between the first and second positioning rings. The second positioning ring, which is threaded to the shaft, positions the cable reel, facilitating its installation and removal.
[0018] Furthermore, a limit key is fixedly connected to the inner wall of the winding drum, and a keyway is provided inside the rotating shaft. The limit key is slidably connected to the rotating shaft through the keyway.
[0019] The above solution ensures that the keyed connection can achieve circumferential fixation between the spool and the shaft, allowing the spool to rotate with the shaft. At the same time, the spool can slide axially on the shaft, facilitating the installation and removal of the spool.
[0020] Furthermore, a crossbar is fixedly connected inside the frame, and a collar is slidably sleeved on the outer circumferential surface of the crossbar. Two connecting plates are fixedly connected to the outer circumferential surface of the collar, and the end of the connecting plate away from the collar is fixedly connected to the outer circumferential surface of the first guide wheel.
[0021] The above scheme restricts the first guide wheel, preventing it from rotating with the lead screw and causing it to move laterally at all times, thus ensuring that the yarn is evenly wound on the spool and completing the winding operation.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This filament twisting machine uses a self-balancing yarn tension guiding device. By setting up a shell, slide bar, frame, tension wheel and spring, it can automatically adjust and balance the yarn tension during the yarn winding process, so that the yarn is always in the optimal tension state, improve the flexibility of the device, and ensure the continuous operation of yarn production and processing. During the rotation of the screw, the first guide wheel is driven to move laterally, which can guide the yarn during the yarn winding process, so that the yarn is evenly wound on the winding drum and ensures the winding quality.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 3 and Figure 4This embodiment of a self-balancing yarn tension guiding device for a filament twisting machine includes a frame 1. A housing 2 is fixedly connected to the front of the frame 1. A slide rod 3 is slidably connected to the inside of the housing 2 via a slide groove. A frame 4 is fixedly connected to one side of the slide rod 3. A tension wheel 5 is rotatably connected to the end of the frame 4 away from the slide rod 3. A spring 6 is fixedly connected to the side of the slide rod 3 inside the housing 2. The other end of the spring 6 is fixedly connected to the inner wall of the housing 2. A first motor 7 is fixedly connected to the back of the frame 1. A lead screw 8 is fixedly connected to the output end of the first motor 7. A first guide wheel 9 is threadedly connected to the outer circumference of the lead screw 8. A second motor 10 is fixedly connected to the back of the frame 1. A rotating shaft 11 is fixedly connected to the output end of the second motor 10. A yarn spool 12 is slidably sleeved on the outer circumference of the rotating shaft 11. A second guide wheel 13 is rotatably connected to the top of the frame 1.
[0033] Please see Figure 1 , Figure 3 and Figure 4 The tensioning wheel 5, the first guide wheel 9, and the second guide wheel 13 all have annular grooves inside. The inside and edges of the annular grooves of the tensioning wheel 5, the first guide wheel 9, and the second guide wheel 13 are all arc-shaped. The design of the annular grooves with arc-shaped inside and edges can effectively reduce the friction between the yarn and the wheel surface when the yarn passes through each wheel, reduce the wear of the yarn caused by friction, and ensure the quality of the yarn. At the same time, the arc-shaped edges can prevent the yarn from getting stuck or snagged during the turning process, making the yarn feeding smoother and improving the stability and reliability of the yarn guiding process.
[0034] Please see Figure 1 , Figure 2 and Figure 3 The slide bar 3 has a rectangular structure, and the internal groove of the outer shell 2 is a rectangular groove that matches the slide bar 3. The rectangular structure of the slide bar 3 and the matching rectangular groove can prevent the slide bar 3 from rotating during sliding, ensuring that the slide bar 3 always maintains a stable linear motion. This makes the position adjustment of the tension wheel 5 more precise, ensuring that the tension wheel 5's adjustment of yarn tension is stable and reliable, thereby improving the working accuracy of the entire yarn tension guiding device.
[0035] Please see Figure 1 and Figure 2 The top of the frame 1 is fixedly connected to the mounting bracket 14, and the inside of the mounting bracket 14 is fixedly connected to the twister 15. The mounting bracket 14 can ensure the stability of the twister 15 installation, and the twisting operation of the yarn can be completed through the twister 15.
[0036] Please see Figure 1 and Figure 3A limiting block 16 is fixedly connected to the upper surface of the slide bar 3, and a limiting hole 17 is opened inside the outer shell 2. The outer surface of the limiting block 16 is slidably connected to the outer shell 2 through the limiting hole 17, which effectively limits the sliding stroke of the slide bar 3, prevents the slide bar 3 from exceeding the safe range during sliding, and avoids abnormal position of the tension wheel 5 due to excessive sliding of the slide bar 3. This ensures that the tension wheel 5 adjusts the yarn tension within a reasonable range, thereby improving the safety and stability of the device.
[0037] Please see Figure 1 , Figure 4 and Figure 5 A first positioning ring 18 is fixedly sleeved on the outer circumferential surface of the rotating shaft 11, and a second positioning ring 19 is threadedly connected to the outer circumferential surface of the rotating shaft 11 through a threaded structure. The winding drum 12 can be installed between the first positioning ring 18 and the second positioning ring 19. The second positioning ring 19, which is threadedly connected to the rotating shaft 11, completes the positioning of the winding drum 12, which facilitates the installation and disassembly of the winding drum 12.
[0038] Please see Figure 5 The inner wall of the cable reel 12 is fixedly connected with a limit key 20, and the inside of the rotating shaft 11 is provided with a keyway 21. The limit key 20 is slidably connected to the rotating shaft 11 through the keyway 21. The key connection can ensure that the cable reel 12 and the rotating shaft 11 are circumferentially fixed, so that the cable reel 12 can rotate together with the rotating shaft 11. At the same time, the cable reel 12 can also slide axially on the rotating shaft 11, which facilitates the installation and disassembly of the cable reel 12.
[0039] Please see Figure 1 , Figure 2 and Figure 4 A crossbar 22 is fixedly connected inside the frame 1. A collar 23 is slidably sleeved on the outer circumference of the crossbar 22. Two connecting plates 24 are fixedly connected to the outer circumference of the collar 23. The end of the connecting plate 24 away from the collar 23 is fixedly connected to the outer circumference of the first guide wheel 9, which restricts the first guide wheel 9 and prevents the first guide wheel 9 from rotating with the lead screw 8. This causes the first guide wheel 9 to always move laterally, so that the yarn is evenly wound on the winding drum 12 to complete the winding operation.
[0040] This embodiment discloses a self-balancing yarn tension guiding device for a filament twisting machine. By setting up a housing 2, a slide bar 3, a frame 4, a tensioning wheel 5, and a spring 6, it can automatically adjust and balance the yarn tension during the yarn winding process, ensuring that the yarn is always in the optimal tension state, improving the flexibility of the device, and ensuring the continuous operation of yarn production and processing. During the rotation of the lead screw 8, the first guide wheel 9 is driven to move laterally, which can guide the yarn during the yarn winding process, so that the yarn is evenly wound on the winding drum 12, ensuring the winding quality.
[0041] It should be noted that both the first motor 7 and the second motor 10 are servo motors.
[0042] The working principle of the above embodiments is as follows:
[0043] During the winding operation, the yarn twisted by the twister 15 passes sequentially through the annular grooves of the second guide wheel 13, the tension wheel 5, and the first guide wheel 9, and finally winds onto the drum 12. During the winding operation, the second motor 10 drives the rotating shaft 11 to rotate, which in turn drives the drum 12 to rotate, thus completing the winding operation. During the winding operation, when the yarn tension changes, the tension wheel 5 drives the slide bar 3 to slide in the groove of the outer casing 2 through the frame 4. When the slide bar 3 slides, the spring 6 fixed on one side is compressed or stretched. With the elasticity of the spring 6, the tension wheel 5 can always move to match the yarn tension, thereby automatically adjusting and balancing the yarn tension, keeping the yarn in the optimal tension state and improving the flexibility of the device. During the winding operation, the first motor 7 also needs to be started to drive the lead screw 8 to rotate. The lead screw 8 drives the first guide wheel 9 to move back and forth, guiding the yarn in the winding and making the yarn evenly wound on the drum 12, ensuring the continuous and normal operation of the winding operation.
