Description

Technical Field

[0001] The present invention belongs to the technical field of carbon fiber winding equipment, and particularly relates to a multi-bundle fiber spiral circumferential winding integrated equipment for multi-specification pressure vessels. Background Art

[0002] As a multi-functional engineering material, carbon fiber composite materials have the characteristics of high strength, high stiffness, excellent corrosion resistance and high temperature resistance. Moreover, the fiber winding technology is the earliest developed and most widely used processing technology, and is also one of the very important production technologies. During the storage of high-pressure gas cylinders and the transportation of hydrogen pipelines, the safety performance of containers and pipelines is the most important part. Using the carbon fiber composite material layer as the carrier of high-pressure vessels and transportation pipelines can better ensure their safety performance.

[0017] The technical solution provided by the embodiment of the present invention has the following beneficial effects compared with the prior art:

[0018] A multi-beam fiber spiral circumferential winding integrated device for multi-specification pressure vessels provided by the embodiment of the present invention realizes the functions of flexible gear design and the change of the number of guide yarn shafts in gears on the basis of realizing the integrated design of spiral winding and circumferential winding, avoiding the problem of single production products. At the same time, the shift paddle, the three-layer shaft tube, the gear driving disk and the annular guide disk are integrated, avoiding the problem that the traditional shifting device occupies a large axial volume and must reserve a shifting space. It has a high degree of modularization, rapid and accurate shifting positioning, small occupied volume, and can replace different shift paddles to realize the application of any number of gear bundles winding, improving the application range and space utilization rate. While increasing the synchronous wire feeding quantity of the spiral winding of the equipment, the interference of the driving gears is avoided, providing a new solution for the winding of carbon fiber composite materials to make multi-specification high-pressure gas cylinders and conveying pipelines.

[0019] By adopting a three-layer shaft tube integrated structure, the outermost layer of the shaft tube adopts a hollow continuous spiral groove design, that is, a spiral shaft tube, and its two ends are fixed in the mounting hole positions of the shaft tube mounting rack through bearings. The inner layer of the shaft tube, that is, the limiting shaft tube, realizes the positioning and control of the innermost layer of the guide yarn shaft tube. At the same time, the axial movement control and the self-rotation movement control of the limiting shaft tube are separated. The axial movement control is driven by the gear driving disk of the first slide rail adopting a mathematical curve, and the annular guide disk positions and guides, improving the axial movement control accuracy of the guide yarn shaft tube. The design of separating the shifting and the axial feeding control avoids the interference between the two movement controls and realizes the integrated coupling of multiple movement functions.

[0020] 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.

[0021] 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.

[0022] 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 bracket 2.6 is connected to the extending end of the electric thrust device 3. The yarn guide hole 2.2 is arranged at one end of the bracket 2.6 connected to the electric thrust device 3. The adjusting and detecting roller 2.1 is rotatably arranged on the bracket 2.6. The impregnating tank 2.3 is arranged below the adjusting and detecting roller 2.1. The yarn splitting roller 2.4 and the second yarn guide roller 2.5 are arranged at one end of the bracket 2.6 away from the yarn guide hole 2.2. The fiber filament bundle in the fiber yarn roll fixing roller 6 passes through the first yarn guide roller 5, passes through the yarn guide hole 2.2 and enters the adjusting and detecting roller 2.1, is impregnated in the impregnating tank 2.3, and is split by the yarn splitting roller 2.4 and the second yarn guide roller 2.5, so as to supply the fiber filament bundle to the circumferential winding unit.

[0053] Refer to Figure 13 and Figure 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. A number of bearing seats 14 are evenly arranged on the outer edge of the shaft tube mounting frame 17. The second driving gear 11 is arranged in 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 and drive with the first driving gear 10 and the second driving gear 11. A space for installing the bearing and the second driving 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 bearing seat 14 integrates two different motions in the axial direction, reduces the axial volume of the device, and can solve the problem of easy circumferential interference of traditional super multi-bundle winding devices.

[0054] The support mechanism 8 includes a first frame 8.1 and a second frame 8.2 which are oppositely arranged, and both the first frame 8.1 and the second frame 8.2 have channels arranged coaxially. The connecting guide disk 1 is connected to the first frame 8.1, and the first gear sleeve 33 is fixed on the second frame 8.2.

[0055] During specific operation, the pressure vessel axially feeds along the central axis of the support mechanism 8 driven by the axial feed mechanism and performs circumferential rotational motion. The telescopic cylinder 35 contracts, thereby driving the clutch mechanism 28 to move axially along the connecting guide disk 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 driving disk 22 to rotate, forcing the external sliding rod 12 to slide along the first slide rail 22.1 and the annular guide disk 23, thereby driving the yarn guiding shaft tube 9.1 to complete the radial feed action through the connecting crank 13. At the same time, the first transmission gear ring 32 rotates to drive the first gear sleeve 33 to rotate, thereby driving the second driving gear 11 engaged with it to perform self-rotation motion, and the yarn guiding shaft tube 9.1 key-connected to it also performs 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. The outer surface of the workpiece to be wound is attached to the fiber bundle extended from the wire outlet head 9.7 at a certain angle. When the radial height of the workpiece to be wound is unified, the wire outlet head 9.7 does not need to perform radial expansion and contraction. When the radial height of the workpiece to be wound fluctuates, the wire outlet head 9.7 also completes the expansion and contraction motion while performing self-rotation motion, and cooperates with the axial feed motion to wind back and forth five to six times to complete the spiral winding process of the pressure vessel.

[0056] Refer to Figure 16As shown in the figure, when shifting gears with spiral winding, taking the example of the highest 120 yarn guiding shaft tubes 9.1 in the figure that can be shifted to the third gear simultaneously, the number of first gear holes 18.1 of the shift paddle 18 is 120, the number of second gear holes 18.2 is 60, and the number of third gear holes 18.3 is 30. When winding the first pressure vessel with the largest winding diameter in the first gear, the second transmission gear ring 30 does not need to be driven by the motor; when winding the second pressure vessel with a smaller winding diameter in the second gear, the 60 sliding gears 16 evenly distributed contract and disengage. At this time, the second transmission gear ring 30 is driven by the second driving member 36 arranged in the support mechanism 8 to drive the second gear sleeve 31 to rotate self - rotatably. Thus, the first driving gear 10 meshed with the sliding gear 16 is driven to rotate, and then the spiral shaft tube 9.2 fixedly connected with it is driven to rotate self - rotatably. Both ends of the spiral shaft tube 9.2 are fixed in the guide groove 17.1 of the shaft tube installation frame 17 through bearings, so as to force the shift lever 9.5 whose top end passes through the spiral slide rail 9.3 to move radially. The limiting shaft tube 9.4 further pushes the yarn guiding shaft tube 9.1 to move radially. At the same time, the cylinder 7 connecting the shift pressing piece 19 contracts, the shift pressing piece 19 relaxes, and the pressing head 9.6 pops out, so as to ensure that the shift lever 9.5 can slide in the chute 18.4. At the same time, the gear driving disc 22 rotates to drive the yarn guiding shaft tube 9.1 to move radially, realizing the feeding of 60 yarn guiding shaft tubes 9.1. After entering the corresponding gear, the cylinder 7 extends, the shift pressing piece 19 moves towards the pressing head 9.6, and the pressing head 9.6 presses down into the positioning hole in the corresponding gear to realize the fixation after shifting gears; when winding the third pressure vessel with the smallest winding diameter in the third gear, the 30 sliding gears 16 evenly distributed contract and disengage. At this time, the second transmission gear ring 30 is driven to rotate, driving the second gear sleeve 31 to rotate self - rotatably. Thus, the first driving gear 10 meshed with the sliding gear 16 is driven to rotate, and then the spiral shaft tube 9.2 fixedly connected with it is driven to rotate self - rotatably. Both ends of the spiral shaft tube 9.2 are fixed in the guide groove 17.1 of the shaft tube installation frame 17 through bearings, so as to force the shift lever 9.5 whose top end passes through the spiral slide rail 9.3 to move radially. The limiting shaft tube 9.4 further pushes the yarn guiding shaft tube 9.1 to move radially. At the same time, the cylinder 7 connecting the shift pressing piece 19 contracts, the shift pressing piece 19 relaxes, and the pressing head 9.6 pops out, so as to ensure that the shift lever 9.5 can slide in the chute 18.4. At the same time, the gear driving disc 22 rotates to drive the yarn guiding shaft tube 9.1 to move radially, realizing the feeding of 30 yarn guiding shaft tubes 9.1. After entering the corresponding gear, the cylinder 7 extends, the shift pressing piece 19 moves towards the pressing head 9.6, and the pressing head 9.6 presses down into the positioning hole in the corresponding gear to realize the fixation after shifting gears.

[0057] If more gear shifts are required for winding requirements, only the structural design of the corresponding gears of the shift paddle 18 that plays a positioning role for the largest fiber bundle needs to be carried out.

[0058] After the spiral winding is completed, without cutting the spiral-wound fiber bundle, the pressure vessel is transported to the circumferential 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, causing the external sliding rod 12 to disengage from the first slide rail 22.1 of the gear driving disc 22. At the same time, the telescopic cylinder 35 connecting the clutch mechanism 28 relaxes, and the pressing device 27 presses the second friction plate 24 onto the first friction plate 25 to achieve power transmission. While driving the connecting guide disc 1 to rotate, the electric thrust device 3 performs an axial telescopic movement. Furthermore, the annular fixed disc 4 and the beam collecting device 2 complete the axial and circumferential rotations, thereby completing the circumferential winding of the pressure vessel. During the circumferential winding, the fiber bundle from the fiber yarn reel fixing roller 6 is guided by the first yarn guide roller 5 and then enters the yarn guide hole 2.2. Then, after adjusting the detection roller 2.1 and impregnating in the impregnation tank 2.3, the fiber bundle is fed normally through the yarn separating roller 2.4 and the second yarn guide roller 2.5.
