Description

Technical Field

[0001] This utility model relates to the field of yarn winding technology, and in particular to a winding device for yarn production. Background Technology

[0002] Winding is a crucial step in yarn processing, directly impacting the quality of the yarn and production efficiency. Consistent winding quality ensures that the yarn is less prone to breakage, tangling, or wear during storage, transportation, and subsequent weaving, thereby improving overall production efficiency.

[0003] Currently, when winding yarn, winding equipment is mainly used to wind the yarn that has passed through the guiding mechanism. The uniform distribution of the yarn on the winding drum is achieved by moving the guiding mechanism.

[0004] For example, an automatic yarn winding machine disclosed in patent application number CN202121785185.3 has a main structure including an operating table, a winding device set on one side of the top surface of the operating table, and a guide wheel on the other side. An inverted U-shaped mounting plate is provided in the middle of the operating table. A guide tube is movably arranged laterally inside the U-shaped mounting plate. The guide tube is provided with a guiding mechanism for yarn abrasion prevention (including positioning ring, rubber ring, spring telescopic rod, and fixed guide wheel, etc.). A transmission component (motor, lead screw, threaded tube, etc.) for lifting and lowering the guide tube is provided at the rear end of the U-shaped mounting plate. The friction between the yarn and the guide tube is reduced by the guiding mechanism, and the guide tube is lifted and lowered by the transmission component, so that the yarn is evenly wound on the winding drum.

[0005] It can be seen that the existing patents have the following problems in the yarn winding process: Unstable winding tension can lead to uneven yarn tension if the tension control system lags or lacks precision during the winding process, as the yarn diameter gradually increases. When the yarn diameter changes, the tension is difficult to adjust in real time, which may result in the yarn being too loose and tangled or too tight and breaking.

[0006] Therefore, it is necessary to design a yarn production winding device with real-time tension adjustment. Utility Model Content

[0007] To solve one of the aforementioned technical problems, the present invention provides a winding device for yarn production, comprising a horizontally arranged winding drum. The two ends of the central shaft of the winding drum are inserted into bearing seats on corresponding sides, and the bearing seats are fixedly installed. A winding drive is installed on one side of the outer bearing seat. A winding tension adjustment mechanism is provided on the left side of the winding drum, and a guide mechanism is provided on the left side of the winding tension adjustment mechanism. The yarn produced upstream passes through the guide mechanism and the winding tension adjustment mechanism in sequence before winding onto the winding drum. The winding tension adjustment mechanism is used to adjust the yarn traction angle and tension.

[0008] Based on any of the above technical solutions, a further optimization is made as follows: the winding drive component includes a fixedly installed motor frame, and a main drive motor with a built-in reducer is fixedly installed on the side wall of the motor frame. The output end of the main drive motor is fixedly connected to the central shaft of the winding drum at its corresponding position.

[0009] Based on any of the above technical solutions, a further optimization is made as follows: the winding tension adjustment mechanism includes a rotating roller, the central axis of the rotating roller is on the same horizontal plane as the central axis of the winding drum, a front guide and a rear guide are symmetrically arranged at the top and bottom of the rotating disk, the upstream yarn passes around the front guide and the rear guide in sequence and is pulled downstream to the winding drum, one end of the rotating roller is driven by a rotating motor at its corresponding position, and the rotating motor is fixed on the side wall of a motor mounting base.

[0010] Based on any of the above technical solutions, a further optimization is made as follows: the front guide includes a horizontally arranged front passive roller, and front synchronous telescopic cylinders are respectively arranged at both ends of the front passive roller. The bottoms of the two front synchronous telescopic cylinders are fixedly installed on the outer side wall of the rotating roller, and both ends of the central shaft of the front passive roller are movably inserted into the bushings fixed to the top of the piston rod of the corresponding front synchronous telescopic cylinder.

[0011] Based on any of the above technical solutions, a further optimization is made as follows: the rear guide includes a horizontally arranged rear passive roller, and a rear synchronous telescopic cylinder is respectively provided at both ends of the rear passive roller. The tops of the two rear synchronous telescopic cylinders are fixedly installed on the outer side wall of the rotating roller, and both ends of the central shaft of the rear passive roller are movably inserted into the bushings fixed to the top of the piston rod of the corresponding rear synchronous telescopic cylinder.

[0012] Based on any of the above technical solutions, a further optimization is made as follows: when the yarn is in a traction state, it passes over the top of the front passive roller from front to back, then passes the bottom left side of the rear passive roller, and extends to the right side of the winding drum for winding.

Adjusting sleeves are fixedly installed on the top of the piston rods of the two vertical adjusting cylinders. Each adjusting sleeve is movably sleeved on the outer wall of the central axis of the intermediate adjusting roller.

[0014] Based on any of the above technical solutions, a further optimization is made as follows: when the two vertical adjusting cylinders are working, they are in a synchronous lifting and lowering state. When the two vertical adjusting cylinders are lifting and lowering synchronously, they drive the current intermediate adjusting roller to lift and lower and adjust the gap between it and the horizontal guide rollers on both sides.

[0024] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-4 As shown in the image.

[0025] Example 1: A winding device for yarn production includes a horizontally arranged winding drum 1. The two ends of the central shaft of the winding drum 1 are inserted into bearing seats 2 on corresponding sides, and the bearing seats 2 are fixedly arranged. A winding drive is installed on one side of the outer bearing seat 2. A winding tension adjustment mechanism is arranged on the left side of the winding drum 1. A guide mechanism is arranged on the left side of the winding tension adjustment mechanism. The yarn produced upstream passes through the guide mechanism and the winding tension adjustment mechanism in sequence and is wound onto the winding drum 1. The winding tension adjustment mechanism is used to adjust the yarn traction angle and tension.

[0026] The winding device of this invention supports the winding drum 1 via a fixed bearing seat 2. A winding drive provides driving force to the winding drum 1, enabling it to rotate and wind the yarn. After the yarn is produced upstream, it is first guided by a guiding mechanism, then the traction angle and tension are adjusted by a winding tension adjustment mechanism, and finally wound onto the winding drum 1. The entire process proceeds in the sequence of guiding, tension and angle adjustment, and winding, with each mechanism working together to complete the yarn winding process.

[0027] When this winding equipment is working, the winding drive provides the traction force required for winding. The upstream yarn is continuously pulled downstream under the traction force of the downstream winding drive. When the yarn passes through the guiding mechanism, it can be effectively guided by the two horizontal guide rollers 3 at the bottom and the intermediate adjusting roller 4. When it is necessary to control the pressing force on the screen, the synchronous lifting and lowering of the vertical adjusting cylinders 5 at both ends of the intermediate adjusting roller 4 is controlled to control the pressing of the yarn, thereby cooperating to complete the tension adjustment in the guiding state.

[0028] When the equipment is working, the winding drive generates traction, moving the upstream yarn downstream. As the yarn passes through the guiding mechanism, the two horizontal guide rollers 3 at the bottom provide initial guidance, while the intermediate adjusting roller 4 moves up and down under the drive of the vertical adjusting cylinder 5. When it is necessary to adjust the tension on the yarn, the vertical adjusting cylinder 5 moves up and down synchronously, causing the intermediate adjusting roller 4 to move up and down, changing its relative position with the horizontal guide rollers 3, thereby adjusting the degree of pressure on the yarn and achieving adjustment of the tension during the guiding state.

[0029] After the yarn passes through the guiding mechanism and enters the winding tension adjusting mechanism, the rotation of the rotating roller 7 of the winding tension adjusting mechanism is controlled to achieve the adjustment of the angle of the front guide and the rear guide as needed. This allows the yarn to be pulled to the winding drum 1 at different inclination angles after passing through the front guide and the rear guide, thus achieving effective adjustment as the number of turns of yarn wound on the winding drum 1 varies. When it is necessary to maintain the tension effect of the yarn wound on the winding drum 1, the front guide and the rear guide are controlled to extend or shorten in the radial direction, thereby effectively controlling the tension of the wound yarn and ultimately achieving the purpose of adjusting the tension and the winding entry angle.

[0030] After the yarn enters the winding tension adjustment mechanism, the rotating roller 7 rotates, causing the front guide and rear guide to adjust their positions and angles. After passing through the angle-adjusted front and rear guides, the yarn is drawn to the winding drum 1 at different inclination angles. As the number of yarn loops on the winding drum 1 changes, the tension of the yarn as it passes around the front and rear guides is changed by controlling their radial extension and retraction, thereby adjusting the tension and ultimately achieving a comprehensive adjustment of the tension and winding entry angle.

[0031] When there is a temporary instability in the supply of upstream yarn, the combined action of the guiding mechanism and the winding tension adjustment mechanism can buffer the impact of this instability to a certain extent.

[0032] Based on any of the above technical solutions, a further optimization is made as follows: the winding drive component includes a fixedly installed motor frame 15, and a main drive motor 16 with a built-in reducer is fixedly installed on the side wall of the motor frame 15. The output end of the main drive motor 16 is fixedly connected to the central shaft of the winding drum 1 at its corresponding position.

[0033] The motor frame 15 in the winding drive unit provides fixed support for the main drive motor 16. The main drive motor 16 has a built-in reducer, which can convert the high-speed rotation of the motor into a speed suitable for the winding drum 1. The output end of the main drive motor 16 is fixedly connected to the central shaft of the winding drum 1. When the main drive motor 16 is working, its output torque is transmitted to the winding drum 1 through the central shaft, driving the winding drum 1 to rotate, thereby realizing the winding of the yarn.

[0034] Based on any of the above technical solutions, a further optimization is made as follows: the winding tension adjustment mechanism includes a rotating roller 7, the central axis of the rotating roller 7 is on the same horizontal plane as the central axis of the winding drum 1, a front guide and a rear guide are symmetrically arranged at the top and bottom of the rotating disk, the upstream yarn passes around the front guide and the rear guide in sequence and is pulled downstream to the winding drum 1, one end of the rotating roller 7 is driven by a rotating motor 8 at its corresponding position, and the rotating motor 8 is fixed on the side wall of a motor mounting base 9.

[0035] The rotating roller 7 of the winding tension adjustment mechanism rotates under the drive of the rotating motor 8, which is fixedly supported by the motor mounting base 9. Since the central axis of the rotating roller 7 is on the same horizontal plane as the central axis of the winding drum 1, its rotation drives the symmetrically arranged front and rear guides installed at the top and bottom to rotate synchronously, changing their angles. The upstream yarn passes sequentially around the front and rear guides and is then drawn to the winding drum 1. By changing the angles of the front and rear guides, the angle at which the yarn enters the winding mechanism is adjusted.

[0036] Based on any of the above technical solutions, a further optimization is made as follows: the front guide includes a horizontally arranged front passive roller 10, and front synchronous telescopic cylinders 11 are respectively arranged at both ends of the front passive roller 10. The bottoms of the two front synchronous telescopic cylinders 11 are fixedly installed on the outer side wall of the rotating roller 7. The two ends of the central shaft of the front passive roller 10 are movably inserted into the bushings 12 fixed to the top of the piston rod of the corresponding front synchronous telescopic cylinder 11.

[0037] The bottom of the front synchronous telescopic cylinder 11 of the front guide is fixed to the outer wall of the rotating roller 7, and the two ends of the central shaft of the front passive roller 10 are movably inserted into the bushing 12 at the top of its piston rod. When the front synchronous telescopic cylinder 11 is working, the piston rod extends and retracts, driving the bushing 12 to move, thereby causing the front passive roller 10 to move in the horizontal direction. Since the two front synchronous telescopic cylinders 11 work synchronously, the front passive roller 10 can maintain a horizontal state while moving, thereby changing its relative position with other components and affecting the tension of the yarn.

[0038] Based on any of the above technical solutions, a further optimization is made as follows: the rear guide includes a horizontally arranged rear passive roller 13, and a rear synchronous telescopic cylinder 14 is respectively arranged at both ends of the rear passive roller 13. The tops of the two rear synchronous telescopic cylinders 14 are fixedly installed on the outer side wall of the rotating roller 7. Both ends of the central shaft of the rear passive roller 13 are movably inserted into the bushing 12 fixed to the top of the piston rod of the corresponding rear synchronous telescopic cylinder 14.

[0039] The top of the rear synchronous telescopic cylinder 14 of the rear guide is fixed to the outer wall of the rotating roller 7, and the two ends of the central shaft of the rear passive roller 13 are movably inserted into the bushing 12 at the top of the piston rod. When the rear synchronous telescopic cylinder 14 is working, the piston rod extends and retracts, driving the bushing 12 to move, causing the rear passive roller 13 to move horizontally. The two rear synchronous telescopic cylinders 14 work synchronously to ensure the horizontal movement of the rear passive roller 13. When the yarn passes over the rear passive roller 13, its tension will change due to the change in the position of the rear passive roller 13.

[0040] Example 2: Compared with Example 1, this example also includes the following technical features: Based on any of the above technical solutions, a further optimization is made: when the yarn is in a traction state, it passes over the top of the front passive roller 10 from front to back, then passes through the bottom left side of the rear passive roller, and extends to the side of the winding drum 1 for winding.

[0041] When the yarn is drawn, it moves along a specific path, first passing over the top of the front passive roller 10, then passing the bottom left side of the rear passive roller, then winding to the right, and finally extending to the side of the winding drum 1 for winding. This path design allows the yarn to form a specific angle and contact pattern as it passes over the two rollers, thereby effectively adjusting the yarn tension and winding angle by utilizing the changes in the position and angle of the two rollers.

[0042] Based on any of the above technical solutions, a further optimization is made as follows: the guiding mechanism includes two horizontally spaced guide rollers 3, both of which rotate around a fixed axis. An intermediate adjusting roller 4 is provided between the two horizontally guide rollers 3. Vertical adjusting cylinders 5 are symmetrically arranged at both ends of the central axis of the intermediate adjusting roller 4. The bottom of the vertical adjusting cylinder 5 is fixedly installed. Adjusting sleeves 6 are fixedly installed on the top of the piston rods of the two vertical adjusting cylinders 5. Each adjusting sleeve 6 is movably sleeved on the outer wall of the central axis of the intermediate adjusting roller 4.

[0043] Two horizontal guide rollers 3 of the guiding mechanism are spaced apart and rotate on a fixed axis, providing a basic guiding path for the yarn. An intermediate adjusting roller 4 is located between the two horizontal guide rollers 3, with its central shaft ends connected to the top of the piston rod of the vertical adjusting cylinder 5 via adjusting sleeves 6. The adjusting sleeves 6 are movably fitted onto the outer wall of the central shaft. The bottom of the vertical adjusting cylinder 5 is fixed; when the piston rod extends or retracts, it drives the adjusting sleeves 6 to move up and down, thereby causing the intermediate adjusting roller 4 to move up and down. Because the two vertical adjusting cylinders 5 are symmetrically arranged, the intermediate adjusting roller 4 can maintain a horizontal state during lifting and lowering.

[0044] Based on any of the above technical solutions, a further optimization is made as follows: when the two vertical adjusting cylinders 5 are working, they are in a synchronous lifting and lowering state. When the two vertical adjusting cylinders 5 are lifting and lowering synchronously, they drive the current intermediate adjusting roller 4 to lift and lower and adjust the gap between it and the horizontal guide rollers 3 on both sides.

[0045] Two vertical adjusting cylinders 5 move up and down synchronously, with their piston rods extending and retracting by the same amount, thereby driving the intermediate adjusting roller 4 to move up and down while maintaining a horizontal position. As the intermediate adjusting roller 4 moves up and down, the distance between it and the two horizontal guide rollers 3 on both sides changes, i.e., the gap size changes. When the gap decreases, the pressure on the yarn increases, and the yarn tension increases; when the gap increases, the pressure decreases, and the yarn tension decreases, thus achieving the adjustment of the yarn tension.

[0046] The work process is as follows: Equipment start-up phase: The winding drive unit starts working. The main drive motor 16 with the built-in reducer fixed on the motor frame 15 outputs power, and its output end drives the central shaft of the winding drum 1 to rotate, so that the winding drum 1 starts to rotate and provides traction force for yarn winding.

[0047] Yarn guiding stage: The yarn produced upstream moves downstream under the traction force of the winding drive and first enters the guiding mechanism. The yarn passes through two horizontal guide rollers 3 spaced apart in the guiding mechanism. The two horizontal guide rollers 3 rotate on a fixed axis to provide initial guidance for the yarn.

[0048] Tension adjustment stage of the guiding mechanism: If it is necessary to adjust the tension of the yarn in the guiding mechanism, control the two vertical adjusting cylinders 5 to rise and fall synchronously, driving the intermediate adjusting roller 4 to move up and down, changing the gap between the intermediate adjusting roller 4 and the two horizontal guiding rollers 3 on both sides. If the gap decreases, the pressure on the yarn increases, and the tension increases; if the gap increases, the pressure decreases, and the tension decreases, thus completing the tension adjustment in the guiding state.

[0049] Winding tension adjustment stage: The yarn passes through the guide mechanism and enters the winding tension adjustment mechanism. The rotary motor 8 drives the rotary roller 7 to rotate. Since the central axis of the rotary roller 7 is on the same horizontal plane as the central axis of the winding drum 1, its rotation drives the front guide and the rear guide, which are symmetrically arranged at the top and bottom, to rotate synchronously, thereby achieving angle adjustment and allowing the yarn to be pulled at different tilt angles.

[0050] Tension fine adjustment stage: When it is necessary to maintain the tension of the yarn winding on the winding drum 1, the two front synchronous telescopic cylinders 11 of the front guide extend and retract synchronously, driving the front passive roller 10 to move horizontally; the two rear synchronous telescopic cylinders 14 of the rear guide extend and retract synchronously, driving the rear passive roller 13 to move horizontally. By extending or shortening the front passive roller 10 and the rear passive roller 13 in the radial direction, the tension of the wound yarn is effectively controlled.

[0051] Yarn winding stage: After being adjusted by the winding tension adjustment mechanism, the yarn extends along a specific path (from front to back, passing over the top of the front passive roller 10 and then winding out to the right from the bottom left side of the rear passive roller) to one side of the winding drum 1, and finally winds onto the winding drum 1. As the number of yarn loops on the winding drum 1 changes, the tension and winding entry angle of the yarn are continuously adjusted through the synergistic action of the above mechanisms to ensure that the yarn is wound up in a suitable state.
