Description

Technical Field

[0001] This utility model relates to the technical field of twist adjustment devices, specifically a twist adjustment device for yarns knitted on a full wool circular knitting machine. Background Technology

[0002] In the production of yarn using a circular knitting machine, the twist adjustment method is simple, mostly relying on controlling the difference in speed between yarn release and winding for basic adjustment. There is a lack of coordinated control over key parameters such as yarn path angle and tension, resulting in insufficient twist adjustment accuracy and difficulty in meeting the precise twist requirements of different fabrics. Poor twist uniformity, due to the lack of dynamic guidance of the yarn path and fine adjustment of tension, the yarn is prone to local twisting too loose or too tight due to path deviation and tension fluctuation during winding, which affects the overall quality stability of the yarn. During operation, the yarn is prone to instability and lacks an effective guiding and tension buffering structure, which makes the yarn prone to tangling, breaking or pilling when running at high speed. This not only reduces production continuity but also directly affects the physical properties of the yarn and the subsequent knitting effect. Traditional devices are unable to adapt to diverse production needs. Their adjustment range is limited and their flexibility is insufficient. They cannot quickly adjust twist parameters according to different yarn specifications and fabric types, which restricts the quality improvement and application expansion of wool knitted yarns. Therefore, the industry urgently needs a device that can achieve precise twist control and ensure stable yarn operation through multi-dimensional collaborative adjustment to solve the above-mentioned defects of traditional devices.

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.

[0018] Please see Figures 1-7 This utility model provides a new technical solution: a twist adjustment device for knitting yarn on a full wool circular knitting machine, including a frame 5 fixedly connected to the upper surface of the mounting base plate 1, an adjustment cylinder 10 installed on the upper surface, and a mounting piece 11 connected to the first concave plate 7 on the lower surface, supporting the adjustment cylinder and each auxiliary wheel assembly, which is the core support structure for twist adjustment.

[0019] The concave frame 2 is fixedly connected to the rear side of the upper surface of the mounting base plate 1. The second servo motor 18 is fixedly installed in the concave part, supporting the second servo motor and fixing its position, providing a power basis for the rotation of the yarn bobbin.

[0020] The second servo motor 18 is fixedly installed in the concave part of the concave frame 2, and its output end is fixedly connected to the transmission shaft. It drives the transmission shaft and the mounting disc 3 to rotate, controls the release speed of the yarn bobbin, and forms a speed difference with the take-up roller to adjust the twist.

[0021] The upper end of the drive shaft rotates through the upper surface of the concave frame 2, the lower end is connected to the output end of the second servo motor 18, and the upper end is connected to the mounting disk 3, transmitting motor power and driving the mounting disk to rotate synchronously.

[0022] The mounting disc 3 is fixedly connected to the upper end of the drive shaft and is used to mount the yarn spool. As the drive shaft rotates, it drives the yarn spool to release the yarn, and its rotation speed directly affects the yarn release speed.

[0023] There are two mounting plates 14, which are fixedly connected to the front side of the upper surface of the mounting base plate 1 on the left and right sides respectively. The opposite surfaces are rotatably connected to the fixing parts 23, which support the fixing parts and the take-up roller to ensure the stable operation of the take-up mechanism.

[0024] The fixing member 23 is rotatably connected to the opposite sides of the two mounting plates 14. The left end of the left fixing member passes through the left mounting plate and is connected to the output end of the servo motor. It is used to install the take-up roller and drives the take-up roller to rotate under the drive of the servo motor. The yarn twist is adjusted by the speed difference.

[0025] The servo motor is fixedly installed on the left side of the left mounting plate 14, and its output end is fixedly connected to the left fixing part 23. It drives the fixing part and the take-up roller to rotate, controls the take-up speed, and forms a speed difference with the yarn bobbin release speed.

[0026] The protective box 19 is fixedly connected to the upper surface of the mounting base plate 1 and is located behind the two mounting plates 14. The upper surface has a sliding groove 25, which accommodates the threaded rod 24 and the movable sleeve 27, protects the internal adjustment components and provides installation space.

[0027] The slide groove 25 is formed on the upper surface of the protective box 19 and communicates with the interior, allowing the slider 26 to slide through, providing a channel for the movement of the slider and guide ring, and ensuring smooth adjustment of the guide ring position.

[0028] The first servo motor 15 is fixedly installed on the left side of the protective box 19, and the output end is fixedly connected to the threaded rod 24 to drive the threaded rod to rotate, providing power for the position adjustment of the guide ring and assisting in controlling the uniformity of yarn twist.

[0029] The right end of the threaded rod 24 rotates and penetrates into the interior of the protective box 19 and rotates to connect with the inner wall of the protective box. The left end is connected to the output end of the first servo motor 15. The outer wall is threaded to the movable sleeve 27. By rotating, the movable sleeve moves left and right to achieve the adjustment of the guide ring position.

[0030] The movable sleeve 27 is threaded onto the outer wall of the threaded rod 24, and the upper end is fixedly connected to the slider 26. As the threaded rod rotates, it moves left and right along its length, causing the slider and guide ring to move synchronously.

[0031] The upper end of the slider 26 slides through the inner wall of the groove 25, the lower end is connected to the movable sleeve 27, and the upper end is connected to the guide ring 22. As the movable sleeve moves, it drives the guide ring to move left and right, changing the yarn path angle.

[0032] The guide ring 22 is fixedly connected to the upper end of the slider 26, through which the yarn passes. The angle between the yarn and the take-up roller is adjusted by changing the left and right position, which helps to control the uniformity of yarn tension and twist.

[0033] Two inclined mounting plates 20 are fixedly connected to the rear surface of the protective box 19. The opposite surfaces are rotatably connected to the auxiliary rod 21, which supports the auxiliary rod and makes it tilted to guide the yarn path and prevent the yarn from deviating.

[0034] The auxiliary rod 21 is rotatably connected to the opposite surfaces of the two inclined mounting plates 20, allowing the yarn to pass through the lower surface and assisting in guiding the yarn from the second auxiliary wheel to the guide ring, ensuring smooth yarn operation.

[0035] The adjusting cylinder 10 is fixedly connected to the upper surface of the concave support plate 5. The telescopic end slides through the lower surface of the concave frame and is connected to the third concave plate 17, driving the third concave plate and the third auxiliary wheel to move up and down, adjusting the yarn tension to control the twist.

[0036] The third concave plate 17 is fixedly connected to the telescopic end of the adjusting cylinder 10. The concave part is rotatably connected to the third auxiliary wheel 16, and the left and right sides are connected to the guide rods 9. Under the drive of the adjusting cylinder, the third auxiliary wheel is driven to move up and down to adjust the yarn tension.

[0037] The third auxiliary wheel 16 is rotatably connected to the concave part of the third concave plate 17, allowing the yarn to pass through the upper surface. By moving up and down, the tension of the yarn between the front and rear second auxiliary wheels is changed, affecting the tightness of the yarn twist.

[0038] There are two guide rods 9, which are fixedly connected to the fixed mounting plates on the left and right sides of the third concave plate 17. The upper end slides through the upper surface of the concave support plate 5 and slides along the inner wall of the concave frame as the third concave plate moves up and down, ensuring that the third auxiliary wheel moves smoothly.

[0039] There are two mounting parts 11, which are fixedly connected to the lower surface of the concave support plate 5 and are located on the front and rear sides of the third concave plate 17 respectively. The lower surface is fixedly connected to the second concave plate 12, which supports the second concave plate and the second auxiliary wheel to ensure their stable position.

[0040] The second concave plate 12 is fixedly connected to the lower surface of the two mounting parts 11. The concave part is rotatably connected to the second auxiliary wheel 13, supporting the second auxiliary wheel so that it cooperates with the third auxiliary wheel to form a yarn tension adjustment range.

[0041] The second auxiliary wheel 13 is rotatably connected to the concave part of the two second concave plates 12, allowing the yarn to pass through the lower surface. The two front and rear second auxiliary wheels cooperate with the third auxiliary wheel, and the yarn tension is changed by the up and down movement of the third auxiliary wheel.

[0042] The first concave plate 7 is fixedly connected to the lower surface of the concave support plate 5. The first auxiliary wheel 8 is rotatably connected to the concave part. The mounting brackets 6 are connected to the left and right sides to support the first auxiliary wheel and guide the yarn from the conical cover into the subsequent adjustment mechanism.

[0043] The first auxiliary wheel 8 is rotatably connected to the concave part of the first concave plate 7, allowing the yarn to pass through the upper surface, guiding the yarn path, and ensuring that the yarn smoothly enters between the front and rear second auxiliary wheels.

[0044] There are two mounting brackets 6, which are fixedly connected to the left and right sides of the first concave plate 7, and the conical cover 4 is fixedly connected to the opposite side to support the conical cover and make its position correspond to the yarn entry direction to ensure that the multiple yarns are gathered together.

[0045] The conical cover 4 is fixedly connected to the opposite sides of the two mounting brackets 6, allowing multiple strands of yarn to pass through, gathering the multiple strands of yarn, preventing mutual interference, and ensuring that the yarn remains neat before entering the first auxiliary wheel.

[0046] Example 1:

[0047] like Figure 7 As shown: High-elasticity wool yarn adapter application with guide ring with silicone bumps Scene background When processing high-elasticity wool yarn containing 5% spandex, ordinary smooth guide ring 22 easily causes yarn slippage (slippage rate 15%), resulting in a twist deviation of ±8 twists / meter, affecting the uniformity of fabric elasticity; at this time, the guide ring is replaced with a guide ring with silicone bumps. The ring body is made of aluminum alloy skeleton, the inner wall is vulcanized with 0.5mm thick silicone, and the silicone surface is evenly distributed with hemispherical bumps with a diameter of 1mm (spaced 2mm apart), and the ring opening is rounded (radius 1mm). High-elasticity yarn anti-slip and guidance: Silicone bumps increase friction with the yarn through micro-deformation, reducing the slippage rate to below 3%; the bump spacing is adapted to the diameter of wool yarn (2-3mm) to avoid yarn damage caused by excessive compression; the aluminum alloy skeleton ensures the rigidity of the ring body, and the twist deviation is reduced to ±2 twists / meter.

[0048] Example 2:

[0049] like Figure 6 As shown: Low-twist yarn adaptation application with adjustable angle tilt mounting plate Scene background When processing low-twist wool yarn with a twist of ≤200 twists / meter, the fixed-angle inclined mounting plate 20 causes the yarn to sag and the twist to be easily affected by the ambient airflow (deviation ±4 twists / meter). At this time, the inclined mounting plate is replaced with an adjustable-angle inclined mounting plate. The angle can be adjusted by the drive motor and the connecting fixing rod. The surface of the auxiliary rod 21 is covered with a silicone tube (wall thickness 1mm). The 30° small angle keeps the yarn sag within 2mm, and reduces the twist deviation caused by airflow to ±1 twist / meter; the silicone tube increases the friction coefficient to prevent low-twist yarn from slipping; the angle adjustment can adapt to the needs of low-twist yarn with different counts.

[0050] Example 3:

[0051] like Figure 5 As shown: Low-temperature environment adaptation application of heated auxiliary wheels Scene background In a low-temperature environment with a workshop temperature of ≤15℃, wool yarn will have reduced extensibility due to fiber hardening (20% lower than normal temperature), and will be prone to breakage when adjusting twist. At this time, the third auxiliary wheel 16 is replaced with a heated auxiliary wheel with a built-in 24V heating wire (5W power) and a controllable surface temperature (30-40℃). The wheel surface is coated with Teflon. Heating restores the extensibility of wool fibers to room temperature levels, reducing the breakage rate to 3%; temperatures of 30-40℃ promote the softening of fiber oils, reducing the frictional resistance between the yarn and the wheel surface, and closed-loop temperature control prevents overheating damage to the fibers. The toughened yarn increases the height adjustment margin of the third auxiliary wheel. Combined with the precise control of the adjusting cylinder 10, the twist deviation in low-temperature environments is reduced from ±7 twists / meter to ±2 twists / meter. Furthermore, when using the yarn twist adjustment device for the all-wool circular knitting machine, firstly, multiple yarn bobbins are fixedly installed on the mounting disc 3; Then, one end of the yarn is drawn from multiple yarn bobbins, so that one end of the multiple yarns passes through the inner wall of the conical cover 4, and passes through the upper surface of the first auxiliary wheel 8, then through the lower surface of the second auxiliary wheel 13 located on the rear side, then through the upper surface of the third auxiliary wheel 16, then through the lower surface of the second auxiliary wheel 13 located on the front side, then through the lower surface of the auxiliary rod 21, and then through the inner wall of the guide ring 22. Finally, it is fixed onto the take-up roller; Subsequently, the first servo motor 15 and the second servo motor 18, as well as the first servo motor 15, are activated. When the second servo motor 18 starts, it drives the transmission shaft and the mounting disk 3 to rotate. The yarn bobbin on the mounting disk 3 rotates synchronously with it, releasing the yarn. At the same time, the servo motor on the left starts, driving the corresponding fixing part 23 and the take-up roller to rotate. The take-up roller winds up the yarn. By adjusting the speed difference between the second servo motor 18 and the take-up roller servo motor, the twist of the yarn can be changed: when the speed of the take-up roller is greater than the release speed of the yarn bobbin, the yarn is tightened and twisted. The greater the speed difference, the higher the yarn twist; conversely, the smaller the speed difference, the lower the twist. This achieves basic adjustment of the yarn twist. The first servo motor 15 starts, and its output end drives the threaded rod 24 to rotate. The movable sleeve 27 on the outer wall of the threaded rod 24 moves left and right along its length. The movable sleeve 27 drives the guide ring 22 to move synchronously through the slider 26. The change in the left and right position of the guide ring 22 can adjust the path angle of the yarn before winding. When the guide ring moves to the left, the angle between the yarn and the take-up roller becomes smaller, and the tension is relatively stable. When it moves to the right, the angle becomes larger, and the tension increases slightly. The fine adjustment of the path angle helps to control the uniformity of the yarn twist and avoid local twist being too loose or too tight. The adjustment cylinder 10 is activated, and its telescopic end drives the third concave plate 17 and the third auxiliary wheel 16 to move up and down. The two guide rods 9 slide along the inner wall of the concave support plate 5 to ensure that the third auxiliary wheel 16 moves smoothly. When the third auxiliary wheel 16 moves down, the tension of the yarn between the third auxiliary wheel 16 and the front and rear second auxiliary wheels 13 increases. The increased tension can make the yarn twist tighter and the twist slightly higher. When it moves up, the tension decreases, the twist is relatively loose, and the twist slightly lowers. The twist can be further precisely controlled by tension adjustment to adapt to the twist requirements of different yarns. During operation, the first auxiliary wheel 8, the front and rear second auxiliary wheels 13, and the auxiliary rod 21 guide the yarn path to prevent the yarn from tangling or deviating. The conical cover 4 gathers the multiple strands of yarn to ensure that the yarn remains regular before entering the first auxiliary wheel 8, preventing the multiple strands of yarn from interfering with each other and affecting the uniformity of twist. Among them, by synchronously adjusting the speed difference between the second servo motor 18 and the take-up roller servo motor (basic twist adjustment), the position of the guide ring 22 controlled by the first servo motor 15 (twist uniformity adjustment), and the height of the third auxiliary wheel 16 controlled by the adjusting cylinder 10 (tension auxiliary adjustment), the three can work together to achieve precise adjustment of the twist of the all-wool knitting yarn. This can not only meet the specific twist requirements of different fabrics, but also ensure that the yarn runs smoothly during the adjustment process, reduce yarn breakage or pilling, and thus improve the quality of the all-wool circular knitting yarn.
