[0013] Compared with the prior art, the technical solution provided by the embodiment of the present invention has the following beneficial effects: The embodiment of the present invention provides an integrated device for spiral hoop winding of multiple bundles of fibers for pressure vessels of various specifications. On the basis of realizing the integrated design of spiral winding and hoop winding, it realizes the functions of flexible gear design and gear shifting change of the number of yarn guide shaft tubes, thereby avoiding the problem of producing a single product. At the same time, the shift paddles, the three-layer shaft tube, the gear drive disk and the annular guide disk are integrated into one, thereby avoiding the problem that the traditional shift device occupies a large axial volume and must pre-store shift space. The device has a high degree of modularization, fast and accurate gear shift positioning, and small occupied volume. Different shift paddles can be replaced to realize the application of winding of yarn bundles in any number of gears, thereby improving the scope of application and space utilization. While increasing the number of synchronous wire outputs of the spiral winding of the equipment, the interference of the drive gear is avoided, thereby providing a new solution for the winding of carbon fiber composite materials to produce high-pressure gas cylinders and transportation pipelines of various specifications.

[0014] By adopting a three-layer shaft tube integrated structure, the outermost shaft tube adopts a hollow continuous spiral groove design, that is, a spiral shaft tube, and its two ends are fixed on the mounting holes of the shaft tube mounting frame through bearings. The inner shaft tube, that is, the limiting shaft tube, realizes the positioning and control of the innermost yarn guide shaft tube. At the same time, the axial motion control of the limiting shaft tube is separated from the self-rotation motion control. The axial motion control is driven by the gear drive disk of the first slide rail adopting a mathematical curve, and the annular guide disk is used for positioning and guiding, thereby improving the axial motion control accuracy of the yarn guide shaft tube. The design of separate control of gear shifting and axial feed avoids interference between the two motion controls and realizes the integrated coupling of multiple motion functions.

[0015] By arranging a positioning hole and a slide groove on the end face of the shift paddle, and fixing the shift paddle on the shaft tube mounting frame, the positioning hole ensures that the pressure head can be smoothly extended and positioned, the slide groove can ensure that the shift slide bar slides smoothly, and the second compression spring arranged inside the pressure head ensures that the pressure head can smoothly complete the extension and retraction action. When the shift pressure plate driven by the cylinder is lifted, the second compression spring extends, and the pressure head moves away from the positioning hole to complete the radial movement of the shift slide bar and the yarn guide shaft tube connected to it. When the shift pressure plate is pressed down, the second compression spring is compressed, and the pressure head is embedded in the positioning hole to fix the position of the yarn guide shaft tube, thereby avoiding the problem of interference caused by inconsistent gear switching movement and ensuring accurate positioning.

[0016] By adopting a double-layer friction plate clutch design, the annular winding end of the third transmission gear ring fixes the first friction plate, and the first driving member drives the third transmission gear ring to drive the first friction plate to perform rotational motion. In order to ensure that the gear drive disk is separated from the yarn guide shaft tube at this time, the telescopic cylinder is driven to relax, and the clamping device presses the second friction plate onto the first friction plate to realize power transmission. The third transmission gear ring performs radial motion under the action of thrust to realize the separation of the gear drive disk and the yarn guide shaft tube. The connection is reliable, and instantaneous start and stop are realized. At the same time, the drive of two different motion mechanisms is realized by a first driving member, and the motion interference between the spiral winding unit and the annular winding unit is avoided, which saves costs and reduces the equipment's own weight and floor space.

[0017] This equipment adopts the integration of three-layer shaft tube, shift paddle and its auxiliary mechanism, which not only realizes the circumferential rotation and radial feeding of the yarn guide shaft tube and avoids the interference of multiple movements, but also can change the gear according to the number of shaft tubes of winding products with different diameters, so as to achieve flexible winding. The shifting process is smooth and without setbacks, avoiding the problem of fiber stacking or leaving a lot of gaps, and improving the winding performance of fiber wound products.

The fiber bundle in the fiber yarn roll fixing roller 6 passes through the first yarn guide roller 5 and the yarn guide hole 2.2 to enter the adjusting detection roller 2.1, is dipped in glue in the glue dipping tank 2.3, and is separated by the yarn separation roller 2.4 and the second yarn guide roller 2.5, thereby supplying the fiber bundle to the hoop winding unit.

[0033] Reference Fig.13 and Fig.15 As shown, the shaft tube mounting frame 17 is arranged on the side of the second gear sleeve 31 facing the third transmission gear ring 34, and a plurality of bearing seats 14 are evenly arranged at the outer edge of the shaft tube mounting frame 17. The second drive gear 11 is arranged on the inner ring of the bearing of the bearing seat 14 through the gear sleeve 15. Specifically, the bearing seat 14 has upper and lower spaces for the gear sleeve 15 to mesh with the first drive gear 10 and the second drive gear 11 for transmission. A space for the installation of the bearing and the second drive gear 11 is arranged in the middle of the bearing seat 14. The upper and lower end faces of the bearing seat 14 are hollowed out to facilitate the radial movement of the yarn guide shaft tube 9.1. The end face gear of the spiral shaft tube 9.2 is installed in the lower space of the bearing seat 14. The two different movements are integrated in the axial direction of the bearing seat 14, while reducing the axial volume of the equipment and solving the problem of easy interference in the circumferential direction of the traditional super-multi-beam winding equipment.

[0034] The supporting mechanism 8 comprises a first frame 8.1 and a second frame 8.2 which are arranged opposite to each other, and both the first frame 8.1 and the second frame 8.2 have coaxially arranged channels, the connecting guide plate 1 is connected to the first frame 8.1, and the first gear sleeve 33 is fixed on the second frame 8.2.

[0035] During specific operation, the pressure vessel is driven by the axial feeding mechanism to feed along the central axis of the support mechanism 8 and perform circumferential rotation. The telescopic cylinder 35 performs a contraction movement, thereby driving the clutch mechanism 28 to move axially along the connecting guide plate 1. The clutch mechanism 28 drives the second friction plate 24 away from the first friction plate 25. The third transmission gear ring 34 drives the gear drive plate 22 to rotate, forcing the external slide rod 12 to slide along the first slide rail 22.1 and the annular guide plate 23, thereby driving the yarn guide shaft tube 9.1 through the connecting crank 13 to complete the radial feeding action; at the same time, the first transmission gear ring 32 rotates to drive the first gear sleeve 33 Rotate, thereby driving the second driving gear 11 meshing with it to make self-rotation motion, and the yarn guide shaft tube 9.1 keyed with it also makes self-rotation motion; when one end of the pressure vessel is transported to the end face position of the spiral winding unit, the equipment is started, and the outer surface of the wound part fits with the fiber bundle extended by the wire head 9.7 at a certain angle. When the radial height of the wound part is uniform, the wire head 9.7 does not need to perform radial expansion and contraction. When the radial height of the wound part fluctuates, the wire head 9.7 completes the expansion and contraction motion while making self-rotation motion, and cooperates with the axial feeding motion, and reciprocates and winds five to six times to complete the spiral winding process of the pressure vessel.

[0036] Reference Fig.16As shown, when the spiral winding is shifted, the figure takes the three gears of the yarn guide shaft tube 9.1 with a maximum of 120 bundles that can be shifted at the same time as an example, the first gear hole positions 18.1 of the shift paddle 18 are 120, the second gear hole positions 18.2 are 60, and the third gear hole positions 18.3 are 30. When the first gear pressure vessel with the largest diameter is wound, the second transmission gear ring 30 does not need to be driven by a motor; when the second gear pressure vessel with a smaller diameter is wound, the 60 equally spaced sliding gears 16 are contracted and disconnected. At this time, the second transmission gear ring 30 is driven by the second driving member 36 arranged in the support mechanism 8, driving the second gear sleeve 31 to rotate by itself, thereby passing the sliding gear 1 6 drives the first driving gear 10 meshing with it to rotate, thereby driving the spiral shaft tube 9.2 fixedly connected thereto to rotate, and both ends of the spiral shaft tube 9.2 are fixed in the guide groove 17.1 of the shaft tube mounting frame 17 through bearings, thereby forcing the shift slide bar 9.5 whose top passes through the spiral slide rail 9.3 to move radially, and the limit shaft tube 9.4 further pushes the yarn guide shaft tube 9.1 to move radially, and at the same time, the cylinder 7 connected to the shift pressure plate 19 contracts, the shift pressure plate 19 relaxes, and the pressure head 9.6 pops out, thereby ensuring that the shift slide bar 9.5 can slide in the slide groove 18.4, and at the same time, the gear driving disk 22 rotates to drive the yarn guide shaft tube 9.1 to move radially, realizing six The ten-beam guide shaft tube 9.1 is fed, and after entering the corresponding gear, the cylinder 7 extends, and the shift pressure plate 19 moves toward the pressure head 9.6, and the pressure head 9.6 is pressed down to the positioning hole in the corresponding gear to achieve fixation after the gear shift; when the third-gear pressure vessel with the smallest winding diameter is wound, the thirty equally spaced sliding gears 16 are contracted and disconnected, and at this time, the second transmission gear ring 30 is driven to rotate, driving the second gear sleeve 31 to rotate, thereby driving the first driving gear 10 meshing with it to rotate through the sliding gear 16, thereby driving the spiral shaft tube 9.2 fixedly connected thereto to rotate, and both ends of the spiral shaft tube 9.2 are fixed to the shaft tube mounting frame 17 through bearings. 1, thereby forcing the gear shift slide 9.5 whose top passes through the spiral slide rail 9.3 to move radially, and the limiting shaft tube 9.4 further pushes the yarn guide shaft tube 9.1 to move radially. At the same time, the cylinder 7 connected to the gear shift pressure plate 19 contracts, the gear shift pressure plate 19 relaxes, and the pressure head 9.6 pops out, thereby ensuring that the gear shift slide 9.5 can slide in the slide groove 18.4. At the same time, the gear drive disk 22 rotates to drive the yarn guide shaft tube 9.1 to move radially, realizing the feeding of thirty bundles of yarn guide shaft tubes 9.1. After entering the corresponding gear position, the cylinder 7 extends out, the shift pressure plate 19 moves toward the pressure head 9.6, and the pressure head 9.6 is pressed down to the positioning hole in the corresponding gear position to achieve fixation after gear shifting.

[0037] If the winding requirement requires more gears to be switched, it is only necessary to design the structure of the corresponding gears for the shift paddle 18 that plays a positioning role according to the maximum fiber bundle.

[0038] After the spiral winding is completed, there is no need to cut the spirally wound fiber bundle. The pressure vessel is transported to the hoop winding unit and is in a stationary state. The first driving member drives the third transmission gear ring 34 to rotate, and the first compression spring 20 pops out, so that the external slide rod 12 is separated from the first slide rail 22.1 of the gear driving disk 22. At the same time, the telescopic cylinder 35 connected to the clutch mechanism 28 is relaxed, and the clamping device 27 presses the second friction plate 24 onto the first friction plate 25 to realize power transmission, while driving the connected guide disk 1 to rotate, the electric thrust device 3 performs axial telescopic movement, and then the annular fixed disk 4 and the bundling device 2 complete the axial and hoop rotation, thereby completing the hoop winding of the pressure vessel. During the hoop winding, the fiber bundle from the fiber yarn roll fixing roller 6 is guided by the first guide roller 5 and enters the guide hole 2.2, and then through the adjustment detection roller 2.1 and after being dipped in the dip tank 2.3, the fiber bundle is ensured to be fed normally through the yarn separation roller 2.4 and the second guide roller 2.5.
