Description

Technical Field

[0001] This invention belongs to the technical field of fiber winding equipment, and specifically discloses a vertical multi-bundle fiber winding equipment. Background Technology

[0002] Current mainstream fiber winding processes, whether using single-filament winding or large-filament fiber winding to improve winding efficiency, are essentially single-filament winding. Due to the setting of positive and negative winding angles, this process generates fiber crossing, accumulation, and gaps within the same composite layer, leading to localized stress concentration and defects such as resin-poor and resin-rich zones. This easily causes composite layer failure and reduces the load-bearing capacity of the wound layer. Therefore, a multi-bundle synchronous spiral winding process is proposed. This process breaks through traditional design concepts, achieving simultaneous yarn feeding from multiple nozzles and parallel winding, completely solving the drawbacks of traditional winding processes, fully utilizing the material properties of carbon fiber composites, and achieving reinforcement of hydrogen storage container end caps. Because of the synchronous movement of multiple yarns, compared with single-bundle fiber winding equipment, winding efficiency and product performance are significantly improved.

[0003] Existing multi-fiber winding equipment is mostly horizontal. For example, Chinese patent CN113386330A discloses a novel multi-fiber spiral winding device, and Chinese patent CN116811302A discloses an automatic yarn feeding multi-fiber circumferential winding device and method. However, horizontal multi-fiber winding equipment still has the following shortcomings that need to be improved: 1. In the horizontal multi-bundle winding equipment, multiple sets of fiber nozzles are placed vertically, with horizontal tracks on both sides. Two sets of clamping mechanisms are placed on the tracks respectively. During winding, double-end clamping is required. However, due to gravity, the mandrel will shift downward, reducing the winding accuracy and making it impossible to wind heavy single-end open containers. 2. Due to the vertical arrangement of the yarns in space, the yarns experience different forces at different positions, increasing the difficulty of tension control; 3. Due to the horizontal layout of the tracks, it occupies a large area. Summary of the Invention

The fixed frame is fixedly connected to the arc-shaped yarn guide frame, and the swing frame is oscillatingly connected to the fixed frame through a horizontally set connecting shaft. Two swinging yarn guide rollers are rotatably mounted on the swing frame and symmetrically arranged on both sides of the connecting shaft. The roller shaft of the swinging yarn guide roller is parallel to the connecting shaft; the axis of the fiber nozzle, the center of the fixed yarn guide roller, and the center of the swinging yarn guide roller are all located on the same horizontal plane.

[0006] In the above-mentioned vertical multi-bundle fiber winding equipment, each set of fixed yarn guide rollers includes a yarn guide roller frame, which is fixedly installed on the annular yarn guide frame, and two fixed yarn guide rollers are rotatably installed on the yarn guide roller frame.

[0007] The above-mentioned vertical multi-bundle fiber winding equipment also includes a support frame I; a connecting frame is provided on the inner side of the annular yarn guide frame; the support frame I includes multiple support rings arranged sequentially from top to bottom and support rods connecting the multiple support rings, the center of the support rings and the center of the annular yarn guide frame are located on the same vertical line; the annular yarn guide frame and the uppermost support ring are both fixedly connected to the connecting frame.

[0008] The aforementioned vertical multi-bundle fiber winding equipment also includes a support frame II; the lifting assembly includes a vertical guide rail, a guide rail slider, a lifting platform, and a lifting drive mechanism; the vertical guide rail is fixedly installed on the support frame II; the guide rail slider slides in cooperation with the vertical guide rail; the lifting platform is fixedly installed on the guide rail slider; the lifting drive mechanism drives the guide rail slider to move up and down along the vertical guide rail; the rotary drive mechanism is fixedly connected to the lifting platform.

[0009] In the above-mentioned vertical multi-bundle fiber winding equipment, the lifting drive mechanism is a lifting motor; a sprocket is fixedly installed on the output shaft of the lifting motor, and a chain is meshed on the sprocket.

[0013] Compared with the prior art, the present invention has the following beneficial effects.

[0014] 1. Single-end clamping: Unlike the horizontal multi-bundle winding equipment described in the background art, which clamps and fixes the mandrel at both ends, the vertical multi-bundle fiber winding equipment provided by this invention clamps at one end when winding products. Since the rotation axis of the connecting rod and the mandrel is perpendicular to the ground, it is not affected by the downward gravity. Even with single-end clamping, it will not bend. This solves the problems of horizontal multi-bundle winding equipment requiring double-end clamping and the mandrel shifting downward due to gravity, which affects the winding accuracy. This allows multi-bundle fiber winding technology to wind single-opening containers, increasing the adaptability and applicability of multi-bundle fiber winding technology to single-opening mandrels.

[0015] 2. Uniform yarn stress: The vertical multi-bundle fiber winding device provided by this invention has multiple sets of fiber nozzles horizontally placed on an annular yarn guide frame. The yarn is introduced into the fiber nozzles by the yarn guide frames on both sides. The yarn is uniformly affected by gravity, and after deflection, the yarn finally enters the fiber nozzle for fiber winding. This avoids the uneven force caused by the spatial distribution and drape characteristics of the yarn, greatly improving the winding accuracy of the device. The horizontal yarn guide design simplifies the yarn release and guide path, making the structure simpler and making it easier to control the fiber tension evenly.

[0016] 3. Small footprint: The vertical multi-bundle fiber winding equipment provided by this invention has the advantage of small footprint. It uses a lifting component to replace the horizontal track of the horizontal multi-bundle winding equipment, eliminating the horizontal track that takes up a lot of space. This simplifies the flat equipment into a vertical one, effectively reducing the footprint, increasing space utilization efficiency, and improving the intelligence and precision of the equipment.

[0022] like Figure 1 , Figures 4-7As shown, the lifting assembly is used to drive the core mold rotation assembly to move up and down; the core mold rotation assembly includes a connecting rod 201 and a rotation drive mechanism.

The annular nozzle frame 301 is horizontally arranged, and the center of the annular nozzle frame 301 and the central axis of the connecting rod 201 are located on the same vertical line. Multiple fiber nozzles 302 are evenly arranged around the annular nozzle frame 301. Each fiber nozzle 302 is arranged radially along the annular nozzle frame 301. Each fiber nozzle 302 can rotate around its own axis and be fed radially along the annular nozzle frame 301. In conjunction with the lifting assembly and the mandrel rotation assembly, it controls the yarn 9 to be stably wound onto the surface of the mandrel 8. The yarn guiding assembly includes an annular yarn guide frame 401 and an arc-shaped yarn guide frame 402. The annular yarn guide frame 401 surrounds the outside of the multi-bundle fiber winding assembly. The center of the annular yarn guide frame 401 coincides with the center of the annular nozzle frame 301. Fixed components corresponding to the fiber nozzles 302 are installed on the annular yarn guide frame 401. Fixed yarn guide roller groups; each fixed yarn guide roller group includes two vertically rotating fixed yarn guide rollers 403, the angle between the center line connecting the two fixed yarn guide rollers 403 and the axis of the fiber nozzle 302 remains fixed; two arc-shaped yarn guide frames 402 are symmetrically arranged on both sides of the annular yarn guide frame 401, each arc-shaped yarn guide frame 402 is equipped with a swinging yarn guide roller group, with the axis of symmetry between the two arc-shaped yarn guide frames 402 as the dividing line, the swinging yarn guide roller groups on the same side of the dividing line correspond one-to-one with the fixed yarn guide roller groups; each swinging yarn guide roller group has It includes a fixed frame 404, a swing frame 405, and a swing-type yarn guide roller 406. The fixed frame 404 is fixedly connected to the arc-shaped yarn guide frame 402. The swing frame 405 is swing-connected to the fixed frame 404 through a horizontally set connecting shaft 407.

The axis of the fiber nozzle 302, the center of the fixed yarn guide roller 403, and the center of the swing-type yarn guide roller 406 are all located on the same horizontal plane.

[0023] The rotation and radial feeding of the fiber nozzle 302 are existing technologies.

[0025] like Figure 8and Figure 9 As shown, during the winding process, the yarn 9, which consists of multiple fibers, needs to be deflected and redirected: After the yarn 9 is stably drawn out by the unwinding assembly, it first passes through the outer oscillating yarn guide roller 406, and then through the fixed yarn guide roller 403, which changes the yarn 9 from a horizontal state to a vertical state, thereby deflecting the yarn 9. Finally, the yarn is wound onto the surface of the core mold 8 by the fiber nozzle 302 according to a preset trajectory. The angle of the oscillating yarn guide roller 406 can be adjusted according to the real-time position of the yarn 9.

[0026] like Figure 9 As shown, the yarn 9 forms an S-shape as it passes through both the oscillating guide roller 406 and the fixed guide roller 403, fitting snugly against the guide rollers on both sides to ensure stable overlap of the yarn 9. To maintain the stability of the yarn 9's offset and direction, a preset distance should be maintained between the fixed guide roller 403 and the corresponding oscillating guide roller 406, which in this embodiment should be greater than 25cm.

[0027] like Figure 7 As shown, in order to facilitate the installation of the fixed yarn guide roller 403 and the adjustment of its angle, each set of fixed yarn guide rollers includes a yarn guide roller frame 408. The yarn guide roller frame 408 is fixedly installed on the annular yarn guide frame 401, and the two fixed yarn guide rollers 403 are rotatably installed on the yarn guide roller frame 408.

[0028] like Figure 6 and Figure 10 As shown, a connecting frame 409 is provided on the inner side of the annular yarn guide frame 401; the support frame I5 includes multiple support rings arranged sequentially from top to bottom and a support rod connecting the multiple support rings, the center of the support rings and the center of the annular yarn guide frame 401 are located on the same vertical line; the annular yarn guide frame 401 and the uppermost support ring are fixedly connected to the connecting frame 409, thereby realizing the suspended setting of the multi-bundle fiber winding assembly and the yarn guide assembly.

[0029] like Figure 6 As shown, in this embodiment, the connecting frame 409 includes multiple arc-shaped rods, the two ends of which are connected to the inner side of the annular yarn guide frame 401. While reducing weight, it ensures the stable operation of the multi-fiber winding assembly and the yarn guide assembly, thereby ensuring stable winding.

[0030] like Figure 2 and Figure 3 As shown, the lifting assembly includes a vertical guide rail 101, a guide rail slider 102, a lifting platform 103, and a lifting drive mechanism; the vertical guide rail 101 is fixedly mounted on the support frame II6; the guide rail slider 102 is slidably engaged with the vertical guide rail 101; the lifting platform 103 is fixedly mounted on the guide rail slider 102; the lifting drive mechanism drives the guide rail slider 102 to move up and down along the vertical guide rail 101; the rotary drive mechanism is fixedly connected to the lifting platform 103, thereby realizing the up and down movement of the rotary drive mechanism.

[0031] like Figure 2 and Figure 3 As shown, in the above-mentioned vertical multi-bundle fiber winding equipment, the lifting drive mechanism is a lifting motor 104; a sprocket 105 is fixedly installed on the output shaft of the lifting motor 104, and a chain 106 is meshed on the sprocket 105. The two ends of the chain 106 are respectively connected to the lifting platform 103 and the counterweight I 107, and the counterweight I 107 is vertically slidingly engaged with the support frame II 6. When the sprocket 105 rotates, the lifting platforms 103 and the counterweight I 107 on both sides are raised and lowered.

[0032] like Figures 1-3 As shown, in the above-mentioned vertical multi-bundle fiber winding equipment, a counterweight block II7 is also placed on the support frame II6 to balance the front and rear gravity of the support frame II6 and improve the stability of the support frame II6.

[0033] like Figure 1 and Figure 4 As shown, in the above-mentioned vertical multi-bundle fiber winding equipment, the rotary drive mechanism is a rotary motor 202; the outer shell of the rotary motor 202 is fixed on the motor bracket 203, the motor bracket 203 is fixedly connected to the lifting platform 103, the output shaft of the rotary motor 202 passes through the motor bracket 203 and is fixedly connected to the three-jaw chuck 204, and the three-jaw chuck 204 clamps the upper end of the connecting rod 201.

[0034] like Figure 2 As shown, in the above-mentioned vertical multi-bundle fiber winding equipment, the lifting assembly also includes a drag chain 108, and a cable for powering the rotary motor 202 is installed inside the drag chain 108.

[0035] The aforementioned vertical multi-bundle fiber winding equipment has four degrees of freedom: the feeding and rotational motion of the fiber nozzle 302, and the vertical and rotational motion of the mandrel 8. By placing multiple circumferentially arranged fiber nozzles 302 horizontally, the problem of uneven force on multiple bundles of yarn 9 is solved. Furthermore, it eliminates the need to consider deflection issues caused by single-end clamping or weight, ensuring winding stability even under single-end clamping conditions. This effectively improves the equipment's process range, reduces process difficulty, enhances the molding performance of multi-bundle fiber products, and reduces the equipment's footprint. It can wind single-end open containers, long cantilever structures, and other similar products.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
