Description

Technical Field

[0001] This invention relates to the field of fiber winding molding equipment, and more particularly to a carbon fiber spiral winding device with multiple synchronously moving bundles. Background Technology

[0002] Carbon fiber composites, with their excellent mechanical properties and stable chemical properties, are widely used in aerospace, weaponry, transportation, and marine engineering, with broad application prospects. They are a cutting-edge force driving technological progress and industrial upgrading. One of the most common molding processes is carbon fiber composite winding, which is widely used in weapon missile casings, high-pressure hydrogen storage containers, and other applications. Currently, the more mature winding processes are single-bunch helical winding and single-bunch circumferential winding. However, due to the low efficiency of single-bunch winding and the stress concentration problems caused by the cross-branching of carbon fiber composites, multi-bunch winding equipment has emerged.

[0003] For example, Chinese Patent CN113386330A discloses a novel multi-bundle fiber spiral winding device with an internal meshing layout of a large gear and a small gear. In this structure, the size of the large gear cannot be too large, limiting the number of small gears that can be placed inside the large gear, which in turn limits the number of guide tubes, thus failing to maximize winding efficiency. Furthermore, due to the narrow internal space of the device, the maintenance and disassembly of the spiral winding device are cumbersome, increasing downtime for maintenance. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a carbon fiber helical winding device with multiple synchronously moving bundles.

The support mechanism includes a base plate, a left side plate, and a right side plate, with the left side plate and the right side plate fixed parallel and spaced apart to the upper surface of the base plate; The driving mechanism includes a driving assembly, a first large gear ring, and a second large gear ring. The first large gear ring is fixed to the left side plate by a first support bearing, and the second large gear ring is fixed to the right side plate by a second support bearing. The outer rings of the first large gear ring and the second large gear ring are respectively meshed with a first pinion and a second pinion. The driving assembly is used to drive the first large gear ring and the second large gear ring to rotate. The number of feeding mechanisms is the same as the number of first pinions, and they are used to perform lifting and lowering movements under the action of the first pinions. The number of rotating wire guide mechanisms is the same as the number of second pinions, and the rotating wire guide mechanisms are connected to the corresponding feed mechanisms to rotate and guide the wire under the action of the second pinions.

[0005] Preferably, the feeding mechanism includes a first housing and a feeding gear shaft. The first housing is bolted to the left side plate. The feeding gear shaft is fixed inside the first housing by two sets of bearings. The left end of the feeding gear shaft is keyed to a first pinion. The right end of the feeding gear shaft is connected to a rotating shaft via a coupling. A rotating gear is keyed to the rotating shaft, and the rotating gear meshes with a rack.

[0006] Preferably, the rotating wire guide mechanism includes a second housing, a rotating gear shaft, a wire guide tube, a third housing, a shift fork, a locking ring, and a clamp. The second housing is bolted to the right side plate. The rotating gear shaft is fixed inside the second housing by two sets of bearings. The right end of the rotating gear shaft is keyed to a second pinion. The left end of the rotating gear shaft meshes with a first bevel gear. The outer wall of the wire guide tube is keyed to a second bevel gear. The first bevel gear meshes with the second bevel gear. The third housing is fixed to the left side of the second housing. The rotating gear, the first bevel gear, and the second bevel gear are all located inside the third housing. The rotating shaft is fixedly connected to the third housing by bearings. The second bevel gear is fixedly connected to the third housing by bearings. The rack and the wire guide tube are slidably connected to the third housing. The top of the rack is fixedly connected to the shift fork by a locking ring. The clamp is fixedly connected to the top of the wire guide tube. The fork of the shift fork is engaged in the clamp. A wire guide nozzle is fixedly connected to the bottom of the wire guide tube. A wire guide assembly is installed at the top of the wire guide tube.

[0007] Preferably, the wire guide assembly includes a U-shaped frame, which is fixedly connected to the top end of the wire guide tube, and two wire guide rollers are rotatably connected inside the U-shaped frame.

[0008] Preferably, the drive assembly includes two electric push rods, the cylinders of the two electric push rods are movably connected to the left and right sides of the base plate respectively, and the piston rods of the two electric push rods are movably connected to the sides of the first and second large gear rings that are far apart from each other.

[0009] Preferably, the drive assembly includes two motor brackets, which are fixedly connected to the sides of the first and second large gear rings that are far apart from each other. A drive motor is fixedly connected to the motor brackets. Circular racks are fixedly connected to the inner rings of both the first and second large gear rings.

[0011] All of the above-mentioned optional technical solutions can be combined arbitrarily, and the present invention will not provide a detailed description of the structure after each combination.

[0012] By means of the above solution, the beneficial effects of the present invention are as follows: By meshing a first pinion and a second pinion onto the outer rings of the first and second large gear rings respectively, an external meshing layout is adopted. Compared to an internal meshing layout, this significantly increases the number of feeding mechanisms and rotating wire guiding mechanisms (wire guide tubes). The number of wire guide tubes directly determines the number of carbon fiber bundles that the equipment can simultaneously wind. Therefore, this invention can significantly improve the winding efficiency of multiple carbon fiber bundles. In addition, the external meshing layout of the large gear ring and pinion avoids the cumbersome steps of disassembling the large gear ring and then disassembling and reassembling the pinion due to the narrow inner space, shortening equipment maintenance downtime, improving maintenance efficiency, and ensuring continuous production of multiple carbon fiber bundles.

[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] like Figures 1 to 11 As shown, the multi-beam synchronous motion carbon fiber spiral winding device provided in the embodiment of the present invention includes a support mechanism 1, a drive mechanism 2, several sets of feeding mechanisms 3, and several sets of rotating wire guiding mechanisms 4. The support mechanism 1 includes a base plate 1-1, a left side plate 1-2 and a right side plate 1-3, with the left side plate 1-2 and the right side plate 1-3 fixed parallel and spaced apart on the upper surface of the base plate 1-1; The drive mechanism 2 includes a drive assembly, a first large gear ring 2-1 and a second large gear ring 2-2. The first large gear ring 2-1 is fixed to the left side plate 1-2 by a first support bearing 2-3, and the second large gear ring 2-2 is fixed to the right side plate 1-3 by a second support bearing 2-4. The outer rings of the first large gear ring 2-1 and the second large gear ring 2-2 are respectively meshed with a first pinion 2-5 and a second pinion 2-6. The drive assembly is used to drive the first large gear ring 2-1 and the second large gear ring 2-2 to rotate. The number of feeding mechanisms 3 is the same as the number of first pinions 2-5, and they are used to perform lifting and lowering movements under the action of the first pinions 2-5. The number of rotating wire guide mechanisms 4 is the same as the number of second pinions 2-6, and the rotating wire guide mechanism 4 is connected to the corresponding feeding mechanism 3, and is used to rotate and guide the wire under the action of the second pinions 2-6.

[0027] Specifically, the outer ring of the first support bearing 2-3 is fixedly connected to the left side plate 1-2, and the inner ring is fixedly connected to the first large gear ring 2-1. The outer ring of the second support bearing 2-4 is fixedly connected to the right side plate 1-3, and the inner ring is fixedly connected to the second large gear ring 2-2.

[0028] The number of the first pinion 2-5 and the second pinion 2-6 is the same. Preferably, the number of the first pinion 2-5 and the second pinion 2-6 is 60, and correspondingly, the number of the feeding mechanism 3 and the rotating wire guide mechanism 4 is also 60 sets.

[0029] In actual operation, the drive assembly drives the first large gear ring 2-1 and the second large gear ring 2-2 to rotate. The first large gear ring 2-1 and the second large gear ring 2-2 drive the first small gear 2-5 and the second small gear 2-6 to rotate synchronously. The rotation of the first small gear 2-5 drives the corresponding feed mechanism 3 to perform lifting and lowering movements. The rotation of the second small gear 2-6 drives the corresponding rotary wire guide mechanism 4 to rotate. When the feed mechanism 3 performs lifting and lowering movements, it drives the corresponding rotary wire guide mechanism 4 to lift and lower synchronously.

[0030] In one specific embodiment, the feeding mechanism 3 includes a first housing 3-1 and a feeding gear shaft 3-2. The first housing 3-1 is bolted to the left side plate 1-2. The feeding gear shaft 3-2 is fixed inside the first housing 3-1 by two sets of bearings. The left end of the feeding gear shaft 3-2 is keyed to the first pinion 2-5. The right end of the feeding gear shaft 3-2 is connected to a rotating shaft through a coupling 3-3. A rotating gear 3-4 is keyed to the rotating shaft, and the rotating gear 3-4 is meshed with a rack 3-5.

[0031] In actual operation, the rotation of the first pinion 2-5 drives the feed gear shaft 3-2, the coupling 3-3 and the rotating shaft to rotate synchronously, which in turn drives the rotating gear 3-4 to rotate. The rotation of the rotating gear 3-4 drives the rack 3-5 to move up and down.

[0032] In one specific embodiment, the rotating wire guide mechanism 4 includes a second housing 4-1, a rotating gear shaft 4-2, a wire guide tube 4-3, a third housing 4-4, a shift fork 4-7, a locking ring 4-8, and a clamp 4-9. The second housing 4-1 is bolted to the right side plate 1-3. The rotating gear shaft 4-2 is fixed inside the second housing 4-1 by two sets of bearings. The right end of the rotating gear shaft 4-2 is keyed to the second pinion 2-6. The left end of the rotating gear shaft 4-2 is meshed with a first bevel gear 4-5. The outer wall of the wire guide tube 4-3 is keyed to a second bevel gear 4-6, and the first bevel gear 4-5 meshes with the second bevel gear 4-6. The third housing 4-4 ​​is fixed to... On the left side of the second housing 4-1, the rotating gear 3-4, the first bevel gear 4-5, and the second bevel gear 4-6 are all located inside the third housing 4-4. The rotating shaft is fixedly connected to the third housing 4-4 ​​through a bearing. The second bevel gear 4-6 is fixedly connected to the third housing 4-4 ​​through a bearing. The rack 3-5 and the guide tube 4-3 are slidably connected to the third housing 4-4. The top of the rack 3-5 is fixedly connected to the shift fork 4-7 through a locking ring 4-8. The clamp 4-9 is fixedly connected to the top of the guide tube 4-3. The fork of the shift fork 4-7 is inserted into the clamp 4-9. The bottom of the guide tube 4-3 is fixedly connected to the guide nozzle 4-10. The top of the guide tube 4-3 is equipped with a guide assembly 4-11.

[0033] In actual operation, the rotation of the second pinion 2-6 drives the rotating gear shaft 4-2 and the first bevel gear 4-5 to rotate synchronously. The rotation of the first bevel gear 4-5 meshes with and drives the second bevel gear 4-6 and the guide tube 4-3 to rotate. At the same time, under the limiting action of the third housing 4-4, the rack 3-5 rises and falls synchronously, driving the guide tube 4-3, the guide nozzle 4-10 and the guide assembly 4-11 to rise and fall synchronously.

[0034] In one specific embodiment, the guide wire assembly 4-11 includes a U-shaped frame 4-11-1, which is fixedly connected to the top end of the guide wire tube 4-3, and two guide wire rollers 4-11-2 are rotatably connected inside the U-shaped frame 4-11-1.

[0035] In practice, when the multiple bundles of carbon fiber filaments are first wound, the multiple bundles of carbon fiber filaments are passed through the guide tube 4-3 between the two guide rollers 4-11-2 of the multiple guide filament assemblies 4-11, and then pulled out from the guide nozzle 4-10 and fixed on the mandrel.

[0036] The driving component in this embodiment of the invention can be implemented through the following two structures: The first type of drive assembly includes two electric push rods 2-7. The cylinders of the two electric push rods 2-7 are movably connected to the left and right sides of the base plate 1-1, respectively. The piston rods of the two electric push rods 2-7 are movably connected to the sides of the first large gear ring 2-1 and the second large gear ring 2-2 that are far apart from each other.

[0037] In one specific embodiment, the cylinder bodies of the two electric push rods 2-7 are movably connected to the left and right sides of the base plate 1-1 respectively via lugs and pins. The lugs are fixedly connected to the base plate 1-1, and the pins are rotatably connected to the lugs. The cylinder bodies of the electric push rods 2-7 are sleeved on the pins. Push rod connecting shafts are fixedly connected to the sides of the first large gear ring 2-1 and the second large gear ring 2-2 that are far apart from each other. The piston rods of the two electric push rods 2-7 are respectively sleeved on the push rod connecting shafts on the sides of the first large gear ring 2-1 and the second large gear ring 2-2 that are far apart from each other.

[0038] In actual operation, the piston rods of the two electric push rods 2-7 drive the first large gear ring 2-1 and the second large gear ring 2-2 to rotate alternately clockwise and counterclockwise within their stroke range, which in turn drives the first small gear 2-5 and the second small gear 2-6 to rotate alternately counterclockwise and clockwise.

[0039] In this structure, the electric push rod 2-7 directly drives the first large gear ring 2-1 and the second large gear ring 2-2, significantly improving the tension uniformity of the multiple carbon fiber filaments and ensuring the strength of the wound product. The winding of multiple carbon fiber filaments requires that the tension of each filament be consistent. This invention can control the synchronous winding of multiple carbon fiber filaments, reducing the risk of cracking of the carbon fiber filaments due to uneven tension.

[0040] The second type of drive assembly includes two motor brackets 2-8, which are fixedly connected to the opposite sides of the first large gear ring 2-1 and the second large gear ring 2-2. A drive motor is fixedly connected to the motor bracket 2-8. Circular racks are fixedly connected to the inner rings of both the first large gear ring 2-1 and the second large gear ring 2-2. The output shafts of the two drive motors mesh with the two circular racks through drive gears.

[0041] In actual operation, the output shafts of the two drive motors drive two circular racks to rotate alternately clockwise and counterclockwise through drive gears, which in turn drive the first pinion 2-5 to rotate once and the second pinion 2-6 to rotate alternately counterclockwise and clockwise.

[0042] The working principle of the multi-bundle synchronous motion carbon fiber spiral winding device provided in this embodiment of the invention is as follows: Before winding multiple bundles of carbon fiber filaments, the multiple bundles of carbon fiber filaments are respectively passed through the guide tube 4-3 between the two guide rollers 4-11-2 of the multiple sets of guide assemblies 4-11, and pulled out from the guide nozzle 4-10 and fixed on the mandrel. After winding of multiple bundles of carbon fiber filaments begins, the external drive device drives the mandrel to reciprocate between the center of the first large gear ring 2-1 and the center of the second large gear ring 2-2 and rotate synchronously, synchronously driving the multiple bundles of carbon fiber filaments to wind onto the mandrel. For different shapes at different positions of the mandrel, the feed assembly can be controlled to lift and lower at different degrees to wind the multiple bundles of carbon fiber filaments.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
