Description

Technical Field

[0001] This utility model relates to the technical field of high-speed yarn winding device with automatic tension adjustment function, and in particular to a high-speed yarn winding device with automatic tension adjustment function. Background Technology

[0002] Yarn is a continuous linear material made from textile fibers (natural or chemical fibers) through processes such as twisting and doubling. It is the basic raw material for weaving fabrics, knitting clothing and other textiles. High-speed yarn winding machines are key equipment in textile production. They are mainly used to wind the yarn produced in the spinning process into bobbins of specific specifications (such as conical bobbins or parallel bobbins) at high speed and evenly to meet the needs of subsequent weaving, dyeing or transportation.

[0003] For example, utility model patent application number 202422366502.8 discloses a high-speed yarn winding machine, including a support plate, a number of mounting blocks fixedly installed on the top of the support plate, and an adjustment mechanism, which includes a slider and an adjustment screw. The slider is threaded onto the adjustment screw, a connecting plate is fixedly installed on the top of the slider, a second motor is fixedly installed on one end of the connecting plate, a rotating shaft is fixedly connected to the output end of the second motor, and a mounting screw is fixedly installed on one end of the rotating shaft.

[0004] Based on existing technology, most high-speed yarn winding devices are single-function, generally requiring manual judgment of yarn tension and corresponding control and adjustment of winding tension. They cannot automatically judge yarn tension and adaptively adjust winding tension, resulting in low automation, inconvenience in use, and fixed winding component structure, making them difficult to adjust and unable to adapt to different amounts of yarn for actual use, thus having low applicability. Therefore, this utility model proposes a high-speed yarn winding device with automatic tension adjustment function to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to propose a high-speed yarn winding device with automatic tension adjustment function, thereby solving the problems that existing high-speed yarn winding devices cannot automatically determine yarn tension and adaptively adjust winding tension, have a low degree of automation, and cannot adapt to different quantities of yarn for winding according to actual usage needs.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a high-speed yarn winding device with automatic tension adjustment function, including a base, a detection frame fixed at the top of the base, a tension detector provided inside the detection frame, lifting frames driven to lift by a lifting adjustment mechanism on both sides of the detection frame, a tension adjustment roller rotatably connected inside the lifting frame, a concave frame fixed at the top of the base away from the detection frame, and support plates symmetrically provided inside the concave frame driven to move by a spacing adjustment mechanism, with yarn winding rollers driven to rotate by a first motor spliced ​​equidistantly between the two sets of support plates.

[0007] A further improvement is that: the output end of the first motor passes through the support plate via a bearing and is fixed with an active rotating plate; a driven rotating plate corresponding to the position of the active rotating plate is rotatably connected to the support plate on the side away from the first motor; both the active rotating plate and the yarn winding roller have a fitting block fixed on the side near the driven rotating plate; and both the driven rotating plate and the yarn winding roller have a fitting groove adapted to the fitting block on the side near the active rotating plate.

[0008] A further improvement is that the spacing adjustment mechanism includes a bidirectional lead screw rotatably connected to the inner side of the concave frame and driven to rotate by a servo motor, and two sets of support plates are respectively threaded onto both sides of the bidirectional lead screw with opposite threading directions.

[0009] A further improvement is that a limiting slider is fixed at the bottom of the support plate, and a limiting groove adapted to the limiting slider is symmetrically opened at the bottom inner side of the concave frame.

[0010] A further improvement is that the lifting adjustment mechanism includes a support frame fixed to the top of the base and a second motor located inside the support frame. The output end of the second motor is fixed with a one-way lead screw, and a threaded plate is threaded onto the one-way lead screw. A sliding rod that slides through the support frame is symmetrically fixed between the threaded plate and the lifting frame.

[0011] A further improvement is that the tension detector is electrically connected to the second motor, and a digital tension reader and a PLC controller electrically connected to the tension detector are fixed at the top of the detection frame.

[0012] A further improvement is that: a square frame is provided on the side of the lifting frame away from the detection frame, and support rods are symmetrically fixed between the bottom end of the square frame and the top end of the base, and guide rollers that are symmetrically distributed vertically are rotatably connected to the inner side of the square frame.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a base, and by clamping several sets of interlocking yarn winding rollers between two sets of support plates, and by driving the two sets of support plates to move in opposite directions through a spacing adjustment mechanism, different numbers of yarn winding rollers can be clamped. Thus, the device can be used to wind different numbers of yarns, making it highly adaptable. Furthermore, by using a tension detector to monitor the tension of the yarn during the transmission process in real time, and by driving the tension adjustment roller to appropriately lower or raise when the yarn is detected to be too loose or too tight, the device achieves automated monitoring of yarn tension and adaptive adjustment of tension. It is convenient to use and has high practicality. Attached Figure Description

Detailed Implementation

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a high-speed yarn winding device with automatic tension adjustment function, including a base 1 fixed to the ground by bolts and a detection frame 2 welded to the top of the base 1. The detection frame 2 is arranged in an inverted U-shape. A tension detector 3 for detecting yarn tension is provided on the inner side of the detection frame 2. A U-shaped lifting frame 4 is provided on both the left and right sides of the detection frame 2. The lifting frame 4 is driven by a lifting adjustment mechanism to move up and down. A tension adjustment roller 5 is rotatably connected to the inner side of the lifting frame 4 through a bearing. The tension detector 3 monitors the tension of the yarn in real time during the transmission process, and drives the tension adjustment roller 5 to appropriately lower or raise when the yarn is detected to be too loose or too tight. To achieve automated monitoring and adaptive adjustment of yarn tension, a concave frame 6 is welded and fixed to the top right of the base 1. Vertically erected support plates 7 are symmetrically arranged on the inner side of the concave frame 6. The two sets of support plates 7 are driven by a spacing adjustment mechanism to move in opposite directions. Several sets of yarn winding rollers 9 are clamped between the two sets of support plates 7. The yarn winding rollers 9 are equidistantly distributed and spliced ​​together. By clamping several sets of spliced ​​yarn winding rollers 9 between the two sets of support plates 7 and driving the two sets of support plates 7 to move in opposite directions through the spacing adjustment mechanism, different numbers of yarn winding rollers 9 can be clamped, so that the device can be used to wind different numbers of yarns.

[0021] The first motor 8 is fixed to the rear outer wall of the rear support plate 7 by bolts. The output end of the first motor 8 passes through the support plate 7 through a bearing and is fixed with an active rotating plate 10. The rear outer wall of the front support plate 7 is rotatably connected to a driven rotating plate 11 through a bearing. The driven rotating plate 11 corresponds to the position of the active rotating plate 10. The active rotating plate 10 and the yarn winding roller 9 are both fixed with a fitting block 12 on the side near the driven rotating plate 11. The driven rotating plate 11 and the yarn winding roller 9 are both provided with a fitting groove 13 on the side near the active rotating plate 10. The fitting groove 13 is adapted to the fitting block 12. By embedding the fitting block 12 into the fitting groove 13, the splicing between several sets of yarn winding rollers 9, active rotating plate 10 and driven rotating plate 11 can be realized.

[0022] The spacing adjustment mechanism includes a servo motor 14 and a bidirectional lead screw 15. The bidirectional lead screw 15 is rotatably connected to the inner side of the concave frame 6 via bearings and is driven to rotate by the servo motor 14. Two sets of support plates 7 are threaded onto both sides of the bidirectional lead screw 15 with opposite threading directions. A limit slider 16 is fixed at the bottom of the support plate 7. A limit groove 17 is symmetrically opened at the bottom of the inner side of the concave frame 6, and the limit groove 17 is adapted to the limit slider 16. Through the cooperation of the limit slider 16 and the limit groove 17, a sliding connection between the support plate 7 and the concave frame 6 is realized. The bidirectional lead screw 15 is driven to rotate by the servo motor 14, so that the support plates 7 threaded onto both sides of the bidirectional lead screw 15 are displaced in opposite directions to adjust the spacing and adapt to different numbers of yarn winding rollers 9.

[0023] The lifting and adjusting mechanism includes a support frame 18 and a second motor 19. The support frame 18 is welded and fixed to the top of the base 1. The second motor 19 is located inside the support frame 18 and is fixed to the top of the base 1 with bolts. A one-way screw 20 is fixed to the output end of the second motor 19. The top of the one-way screw 20 is rotatably connected to the top of the inner side of the support frame 18 through a bearing. A threaded plate 21 is threaded onto the one-way screw 20. A slide rod 22 is symmetrically fixed to the top of the threaded plate 21. The top of the slide rod 22 slides through the top of the support frame 18 and is fixed to the bottom of the lifting frame 4. The one-way screw 20 is driven to rotate by the second motor 19, so that the threaded plate 21 threaded onto the one-way screw 20 moves up and down along the one-way screw 20. During the lifting and lowering process of the threaded plate 21, the lifting frame 4 is driven to lift and lower synchronously through the slide rod 22.

[0024] A digital tension reader 23 and a PLC controller 24 are fixed on the front and rear sides of the top of the testing frame 2, respectively. The tension detector 3 and the PLC controller 24 are connected to drive the second motor 19 to work when the detected tension is too high or too low. The digital tension reader 23 is connected to the tension detector 3 to display the detection value of the tension detector 3.

[0025] A square frame 25 is provided on the side of the lifting frame 4 away from the detection frame 2. Support rods are symmetrically fixed between the bottom end of the square frame 25 and the top end of the base 1. The support rods provide support for the square frame 25. Two sets of guide rollers 26 are rotatably connected to the inside of the square frame 25 and are distributed symmetrically in the upper and lower parts to provide support for the transmitted yarn.

[0026] When high-speed winding of yarn is required, first prepare a corresponding number of yarn winding rollers 9 according to the number of yarns to be wound. Then, splice the yarn winding rollers 9 together and place them between two sets of support plates 7. At the same time, use the spacing adjustment mechanism to drive the two sets of support plates 7 to move towards each other until the spliced ​​yarn winding rollers 9 are clamped between the two sets of support plates 7. Then, pass the ends of the yarns to be wound through the left guide roller 26, the left tension adjustment roller 5, the tension detector 3, the right tension adjustment roller 5 and the right guide roller 26 in sequence, and then fix them on each yarn winding roller 9. Then, start the first motor 8 to drive the yarn winding rollers 9 to rotate at high speed to realize high-speed winding of multiple sets of yarns.

[0027] During the yarn winding process, the tension detector 3 monitors the yarn tension in real time and feeds it back to the digital tension reader 23 for display. When the yarn becomes loose, the tension detector 3 detects a decrease in yarn tension. At this time, it sends a control signal to the PLC controller 24, which drives the second motor 19 to work. The second motor 19 drives the one-way screw 20 to rotate, causing the threaded plate 21 threaded on the one-way screw 20 to descend. During the descent of the threaded plate 21, the lifting frame 4 and the tension adjusting roller 5 descend synchronously through the slide rod 22. By pressing down the yarn, the probability of the yarn becoming loose during winding is reduced, and the winding effect of the yarn is improved. Conversely, if an increase in tension is detected, it indicates that the yarn is too tight. At this time, the tension adjusting roller 5 is driven to rise appropriately to realize automatic tension adjustment during the yarn winding process.
