Description

Technical Field

[0001] This utility model relates to the field of yarn take-up mechanisms, specifically to a yarn take-up mechanism that improves the stability of winding tension. Background Technology

[0002] With the rapid development of science and technology, composite materials, due to their excellent properties of being lightweight and high-strength, are widely used in high-end fields such as aviation, aerospace, petroleum, and chemical industries. As their application scope continues to expand, the market is placing more stringent requirements on the dimensional accuracy and mechanical properties of fiber composite wound products, such as strength and stiffness.

[0003] In fiber winding processes, the winding tension of the fibers is a key parameter that directly affects many core mechanical properties of the wound product. Related research data indicates that improper tension control can lead to a 20%-30% reduction in the strength of the wound product, significantly decreasing its overall performance and ultimately causing it to completely lose its core advantages of being lightweight and high-strength.

[0004] Therefore, the accuracy and stability of fiber tension application play a decisive role in the final quality of fiber-wound products. In summary, improving the precision and stability of tension in the fiber winding process is of paramount practical significance for enhancing the dimensional accuracy and mechanical properties of fiber-wound products. Utility Model Content

[0005] In order to solve the problem that improper tension control in the existing fiber winding process will lead to a decrease in the strength of the wound product and a significant drop in its overall performance, this utility model provides a yarn take-up mechanism that improves the stability of winding tension.

[0006] The technical solution of this utility model is:

[0007] A yarn take-up mechanism for improving winding tension stability includes a frame, a support, a yarn feed roller assembly, a tension roller assembly, a cylinder motion assembly, a gas control assembly, a take-up roller assembly, and a yarn output roller assembly.

[0008] The bracket is fixedly connected to the machine frame, and the yarn feeding roller component, tension roller component, and yarn output roller component are sequentially installed on the bracket along the yarn feeding direction;

[0009] The cylinder moving component, gas control component, and take-up roller component are respectively installed on the frame and located between the tension roller component and the output roller component;

[0010] The tension roller component and the take-up roller component form a tension coordination adjustment structure. The gas control component and the cylinder motion component are pneumatically connected to drive the take-up roller component to move linearly. The yarn is sequentially introduced by the yarn infeed roller component, tension adjusted by the tension roller component, and tension compensated by the take-up roller component before being discharged by the yarn outlet roller component, thus achieving stable control of the yarn tension during the winding process.

[0011] Furthermore, the yarn feed roller assembly includes a hexagonal nut, a yarn guide roller shaft, a deep groove ball bearing C, a yarn guide roller, a shaft spring retaining ring, and a shaft end cap;

[0012] The two ends of the yarn guide roller shaft are rotatably connected to the yarn guide roller via deep groove ball bearings C. The shaft is fitted with a spring retainer ring on the yarn guide roller shaft and axially limits the deep groove ball bearings C. The shaft end cap is fixed to the end of the yarn guide roller shaft by a hexagonal nut.

[0013] Furthermore, the tension roller assembly includes a magnetic powder brake, a bearing housing, a tension roller shaft, a deep groove ball bearing A, a tension roller, and a plug.

[0014] The tension roller shaft is fixed to the bracket via a bearing seat. The magnetic powder brake is driven by the tension roller shaft. The tension roller is rotatably connected to the tension roller shaft via a deep groove ball bearing A. The plug seals the end of the tension roller.

[0015] Furthermore, the tension roller assembly is provided with at least three tension rollers, and each tension roller is evenly distributed at intervals along the axial direction of the tension roller rotation axis;

[0016] After the yarn passes around the three tension rollers, it forms an Ω-shaped yarn path within the tension roller assembly. By adjusting the number of tension rollers the yarn passes through or changing the wrap angle of the yarn on the tension roller surface, the tension requirements of the winding process for different mold sizes can be adapted.

[0017] Furthermore, the cylinder moving parts include a compression spring, a cylinder, a linear shaft protective sleeve, a spring clamping nut, and a cylinder mounting bracket;

[0018] The cylinder is fixed to the frame by a cylinder mounting bracket. The linear shaft protective sleeve is fitted on the outside of the piston rod of the cylinder. The compression spring is fitted on the piston rod. The spring compression nut is threaded to the end of the piston rod and pre-tightens and limits the compression spring.

[0019] Furthermore, the take-up roller assembly includes a take-up roller cylinder, a deep groove ball bearing B, a nylon limiting end cap, a take-up roller shaft, and a take-up roller mounting bracket;

[0020] The take-up roller shaft is fixedly connected to the piston rod of the cylinder in the cylinder moving component through the take-up roller mounting bracket. The take-up roller is rotatably connected to the take-up roller shaft through a deep groove ball bearing B. The nylon limiting end cap is sleeved on both ends of the take-up roller shaft and axially limits the take-up roller.

[0021] Furthermore, the gas control component is connected to the cylinder in the cylinder movement component via an air pipe, and is used to control the extension and retraction movement of the cylinder.

[0022] Furthermore, the structure of the yarn outlet roller assembly is consistent with that of the yarn inlet roller assembly, both including a hexagonal nut, a yarn guide roller shaft, a deep groove ball bearing C, a yarn guide roller, a shaft spring retaining ring, and a shaft end cap.

[0023] Furthermore, the magnetic powder brake is an adjustable torque magnetic powder brake, which can change the reverse resistance of the tension roller by adjusting its output torque.

[0024] Furthermore, the frame and the support are fixedly connected by hexagonal screws, and the yarn feed roller assembly, tension roller assembly, yarn output roller assembly and the support are all detachably connected by hexagonal screws.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] This utility model has a compact structure and is easy to operate. In the fiber winding process, after the yarn is threaded according to the specified process path, the magnetic powder brake and cylinder movement of the tension roller component of the pneumatic yarn winding process will compensate for the changes in yarn tension during the winding process. It is controlled by the program and pressure regulating valve, which makes it easy for operators to operate and the mechanism has a fast response speed, and it can compensate for tension fluctuations in real time during the winding process.

[0027] This invention offers a wide range of yarn tension adjustment. When dealing with winding processes using different mold sizes, the required yarn tension for fiber winding will vary. The yarn carries a certain initial tension. After passing through the pneumatic take-up tension roller mechanism, a magnetic powder brake can be used in conjunction with different tension rollers to change the yarn wrap angle as the yarn passes through different tension rollers. By increasing the tension of the yarn after pneumatic take-up, the tail tension of the yarn can meet the requirements of the fiber winding process, thus satisfying the needs of more winding product processes.

[0028] This invention can adaptively adjust the fluctuation of yarn tension. When the diameter of the conical mold or the mold has different sizes, the yarn tension will change during the winding process. The fluctuation of yarn tension will have a certain impact on the dimensional accuracy and mechanical properties of the wound product. The magnetic powder brake of the tension roller in the pneumatic take-up mechanism increases the reverse torque of the tension roller and the cylinder drives the take-up roller to compensate for the change of yarn tension during the fiber winding process, thereby improving the yarn tension stability during the change of size of the winding mold.

[0047] The cylinder motion component 3, the gas control component 6, and the take-up roller component 16 are respectively installed on the frame 5 and located between the tension roller component 2 and the output roller component 4.

[0048] The tension roller component 2 and the take-up roller component 16 form a tension coordination adjustment structure. The gas control component 6 is pneumatically connected to the cylinder motion component 3 to drive the take-up roller component 16 to move linearly. The yarn is sequentially introduced by the yarn feed roller component 1, tension adjusted by the tension roller component 2, and tension compensated by the take-up roller component 16 before being discharged by the yarn output roller component 4, thereby achieving stable control of the yarn tension during the winding process.

[0049] The frame 5 is assembled with the bracket 9. The bracket 9 is fixedly installed on the top crossbeam of the frame 5 with hexagon socket screws 33, ensuring that the connecting surfaces of the bracket 9 and the frame 5 fit tightly without any looseness or gaps.

[0053] The cylinder moving component 3 includes a compression spring 23, a cylinder 24, a linear shaft protective sleeve 25, a spring clamping nut 26, and a cylinder mounting bracket 22. Specific Implementation Method Two:

[0055] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The yarn feed roller component 1 includes a hexagonal nut 27, a yarn guide roller shaft 28, a deep groove ball bearing C29, a yarn guide roller 30, a shaft spring retaining ring 31, and a shaft end cap 32.

[0056] The two ends of the yarn guide roller shaft 28 are rotatably connected to the yarn guide roller 30 through deep groove ball bearings C29. The shaft spring retainer 31 is sleeved on the yarn guide roller shaft 28 and axially limits the deep groove ball bearings C29. The shaft end cap 32 is fixed to the end of the yarn guide roller shaft 28 by a hexagonal nut 27.

[0057] In the yarn feed roller assembly, deep groove ball bearings C29 are installed at both ends of the yarn guide roller shaft 28. Then, the yarn guide roller shaft 28 with bearings is inserted into the inner hole of the yarn guide roller 30. Shaft spring retaining rings 31 are fitted at both ends of the yarn guide roller shaft 28 to axially position the deep groove ball bearings C29.

[0058] After the deep groove ball bearing C29 is axially positioned, the end cap 32 is finally tightened to the end of the guide roller shaft 28 with the hexagonal nut 27 to complete the assembly of the yarn feed roller component 1; the assembled yarn feed roller component 1 is then fixed to the yarn inlet end of the bracket 9 with the internal hexagonal screw 33. Specific implementation method three:

[0060] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The tension roller component 2 includes a magnetic powder brake 10, a bearing seat 11, a tension roller shaft 12, a deep groove ball bearing A13, a tension roller 14, and a plug 15.

[0061] The tension roller shaft 12 is fixed to the bracket 9 via the bearing seat 11. The magnetic powder brake 10 is driven to the tension roller shaft 12. The tension roller 14 is rotatably connected to the tension roller shaft 12 via the deep groove ball bearing A13. The plug 15 seals and covers the end of the tension roller 14.

[0062] For tension roller assembly, the bearing housing 11 is fixed to the middle position of the bracket 9 with bolts. The tension roller shaft 12 is inserted into the bearing hole of the bearing housing 11. One end of the tension roller shaft 12 is connected to the magnetic powder brake 10 via a coupling. Three deep groove ball bearings A13 are installed at intervals in the middle of the tension roller shaft 12. A tension roller 14 is sleeved on the outside of each bearing. Finally, the end caps 15 are closed at both ends of the tension roller 14 to complete the assembly of tension roller assembly 2, ensuring that the yarn forms an Ω-shaped yarn path after passing through the three tension rollers 14. Specific implementation method four:

[0064] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The tension roller component 2 is provided with at least three tension rollers 14, and each tension roller 14 is evenly distributed along the axial distance of the tension roller shaft 12.

[0065] After the yarn passes around the three tension rollers 14, it forms an Ω-shaped yarn path in the tension roller component 2. By adjusting the number of yarns passing through the tension rollers 14 or changing the wrapping angle of the yarns on the surface of the tension rollers 14, the tension requirements of the winding process for different mold sizes can be adapted.

[0066] During the fiber winding process, the fiber yarn enters the tension roller component 2 through the feed roller 1, passes through the tension roller 14, and forms an Ω-shaped yarn path within the tension roller component 2. After the yarn comes out of the tension roller component 2, it passes through the take-up roller component 16 and then through the exit roller component 4, thus completing the maintenance of the tension change and stable movement of the fiber yarn.

[0068] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The cylinder moving component 3 includes a compression spring 23, a cylinder 24, a linear shaft protective sleeve 25, a spring clamping nut 26, and a cylinder mounting bracket 22.

[0070] The cylinder moving part 6 is assembled by fixing the cylinder mounting bracket 22 to the side of the frame 5 with bolts, fixing the cylinder 24 to the cylinder mounting bracket 22, and putting a linear shaft protective sleeve 25 on the outside of the piston rod of the cylinder 4. Then, the compression spring 23 is put in and the compression spring 23 is pre-tightened and fixed by the spring compression nut 26, thus completing the assembly of the cylinder 3 moving part. Specific implementation method six:

[0072] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The take-up roller component 16 includes a take-up roller cylinder 17, a deep groove ball bearing B18, a nylon limiting end cap 19, a take-up roller shaft 20, and a take-up roller mounting frame 21.

[0073] The take-up roller shaft 20 is fixedly connected to the piston rod of the cylinder 24 in the cylinder moving component 3 through the take-up roller mounting bracket 21. The take-up roller 17 is rotatably connected to the take-up roller shaft 20 through the deep groove ball bearing B18. The nylon limiting end cap 19 is sleeved on both ends of the take-up roller shaft 20 and axially limits the take-up roller 17.

[0074] The take-up roller assembly 16 is assembled by welding the take-up roller shaft 20 to the piston rod end of the cylinder 24 via the take-up roller mounting bracket 21, installing deep groove ball bearings B18 at both ends of the take-up roller shaft 20, and fitting the take-up roller cylinder 17 in the middle of the take-up roller shaft 20 with an interference fit to the outer ring of the deep groove ball bearing B18. Nylon limiting end caps 16 are fitted at both ends of the take-up roller shaft 20 to complete the assembly of the take-up roller assembly 16. Specific implementation method seven:

[0076] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The gas control component 6 is connected to the cylinder 24 in the cylinder movement component 3 via an air pipe, and is used to control the extension and retraction movement of the cylinder 24.

[0077] The gas control component 6 is fixed to the side of the frame 5 with bolts, and the gas control component 6 is connected to the cylinder 24 through the air pipe; the yarn roller component 4 is assembled according to the assembly method of the yarn feed roller component 1, and it is fixed to the yarn outlet end of the bracket 9 with the hexagon socket screw 33. Detailed implementation method eight:

[0079] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving winding tension stability. The structure of the yarn exit roller component 4 is the same as that of the yarn inlet roller component 1, both including a hexagonal nut 27, a yarn guide roller shaft 28, a deep groove ball bearing C29, a yarn guide roller 30, a shaft spring retaining ring 31, and a shaft end cap 32.

[0080] The structure of the yarn output roller component 4 is completely the same as that of the yarn infeed roller component 1. Both include a hexagonal nut 27, a yarn guide roller shaft 28, a deep groove ball bearing C29, a yarn guide roller 30, a shaft spring retaining ring 31, and a shaft end cap 32. The model, assembly relationship, and connection method of each corresponding part are the same.

[0081] The yarn output roller component 4 is detachably installed on the yarn output end of the bracket 9 by means of hexagon socket screws 33. Its installation height is consistent with that of the yarn infeed roller component 1, ensuring that the yarn is in a horizontal or smooth transition state in the yarn path, and avoiding additional tension fluctuations due to height difference.

[0082] Furthermore, the yarn guide roller 30 of the yarn outlet roller component 4 and the yarn guide roller 30 of the yarn inlet roller component 1 have the same specifications and are both made of stainless steel with a polished surface. This can reduce frictional damage to the yarn during the yarn output process. At the same time, in conjunction with the low resistance rotation characteristics of the deep groove ball bearing C29, it ensures that the yarn is smoothly output to the winding die under stable tension, further improving the dimensional accuracy of the winding product. Specific implementation method nine:

[0084] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving the stability of winding tension. The magnetic powder brake 10 is an adjustable torque magnetic powder brake, which can change the reverse resistance of the tension roller 14 by adjusting its output torque. Specific Implementation Method Ten:

[0086] Combination Figure 1 — Figure 9 This embodiment describes a yarn take-up mechanism for improving winding tension stability. The frame 5 and the support 9 are fixedly connected by hexagon socket screws 33. The yarn feed roller component 1, tension roller component 2, and yarn output roller component 4 are all detachably connected to the support 9 by hexagon socket screws 33.

[0087] Initial tension calibration:

[0088] The carbon fiber yarn is sequentially passed through the guide roller 30 of the yarn infeed roller assembly 1, the three tension rollers 14 of the tension roller assembly 2 (forming an Ω-shaped yarn path with a wrap angle of 180°), the take-up roller 17 of the take-up roller assembly 16, and the guide roller 30 of the yarn exit roller assembly 4, and finally connected to the yarn traction mechanism of the winding machine. The initial air pressure is set to 0.5MPa by the pressure regulating valve of the gas control assembly 6, and the output torque of the magnetic powder brake 10 is adjusted to calibrate the tail tension of the yarn so that the initial tail tension of the yarn meets the winding process requirements of the tapered tube.

[0089] Tension compensation during winding process:

[0090] When the winding machine is started, the die begins to rotate and drive the yarn to wind. When the yarn winds to the end of the die, the yarn tends to loosen. The solenoid valve of the gas control component 6 receives the signal and actuates, increasing the air intake pressure of the cylinder 24. This drives the piston rod of the cylinder 24 to extend, causing the take-up roller component 16 to move linearly away from the die, thus winding up and adjusting the loose yarn. At the same time, the torque of the magnetic powder brake 10 automatically increases, increasing the reverse resistance of the tension roller 14, and compensating for tension loss, so that the yarn tension quickly returns to a stable range.
