Description

Technical Field

[0001] This invention relates to the field of plastic molding technology, and in particular to a carbon fiber weaving machine. Background Technology

[0002] Carbon fiber winding machines can wind carbon fiber into shapes that can then be used to weave fabric. If not used to make carbon fiber cloth, this equipment is an automated device used to wind carbon fiber materials into shapes to manufacture hollow or prismatic parts. It can be directly applied to pressure vessels, hydrogen cylinders, aerospace components, and other fields. If used to make carbon fiber cloth, the carbon fiber cloth can be obtained by cutting it from the main line position after winding.

[0003] Carbon fiber winding machines can use dry winding and wet winding. Dry winding directly uses pre-impregnated fiber tape for winding, which requires subsequent heating and curing. Wet winding involves impregnating the fibers with resin before winding, and then curing the resin to form a 3D network structure, which can improve the strength of the product.

[0004] Before winding carbon fiber, it needs to be soaked in an adhesive tank. Existing winding machines require a long soaking time before forming in order to ensure that the carbon fiber yarn is fully soaked, which affects the winding efficiency. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, the present invention provides a carbon fiber weaving machine that ensures the forming effect.

[0006] The technical solution adopted in this invention is: A carbon fiber weaving machine includes a feeding system, a transverse impregnation system, a laying transverse system, a rotary reference system, and a feeding guide device. The transverse impregnation system includes a transverse feed trough, impregnation pressure rollers, and several impregnation guide rollers. The feeding guide device is installed on the side of the transverse feed trough away from the feeding system. The transverse feed trough is mounted on the laying transverse system, and the feeding guide device points towards the rotary reference system. The impregnation pressure rollers and each impregnation guide roller are rotatably mounted within the transverse feed trough. The impregnation pressure rollers include a pressure rotary cylinder, several pressure films, and several pressure flaps. The pressure rotary cylinder is rotatably mounted... Within the transverse material trough, the outer side of the pressurizing rotary cylinder is provided with several pressurizing grooves. The pressurizing membrane is installed within the pressurizing grooves. Each pressurizing flap is closable and installed on its corresponding pressurizing groove. Each pressurizing flap opens and closes its corresponding pressurizing groove when it opens and closes. The pressurizing rotary cylinder is provided with a pressurizing cover. The pressurizing cover is connected to the side of the pressurizing membrane away from the pressurizing flap. The pressurizing cover is connected to an air source through a rotary joint. The pressurizing cover is adapted to the inner wall of the pressurizing rotary cylinder. The pressurizing rotary cylinder is provided with vent holes that communicate with the pressurizing grooves. The pressurizing cover is rotatably installed within the pressurizing rotary cylinder through bearings.

[0007] Preferably, the feeding system includes a feeding rack and a feeding cylinder, wherein the feeding cylinder is rotatably mounted on the feeding rack.

[0008] Preferably, the laying transverse system includes a transverse frame, a transverse motor, a transverse slider, a transverse lead screw, and a transverse rail. The transverse rail is mounted on the transverse frame, and the direction of the transverse rail is consistent with the direction of the rotary reference system. The transverse slider is slidably mounted on the transverse rail. The transverse lead screw is rotatably mounted on the transverse frame. The transverse motor is mounted on the transverse frame, and the transverse lead screw is mounted on the output end of the transverse motor. The transverse material trough is mounted on the transverse slider.

[0009] Preferably, the rotary reference system includes a rotary device, a rotary translation frame, and a spacing adjustment device. The rotary translation frame is slidably mounted on the side of the rotary device. A three-jaw chuck is provided on the side of the rotary device near the rotary translation frame and on the side of the rotary translation frame near the rotary device. A winding reference cylinder is clamped between the rotary device and the rotary translation frame through the three-jaw chuck. The spacing adjustment device is installed between the rotary device and the rotary translation frame.

[0010] Preferably, the feeding guide device includes a plurality of feeding guide rollers, and each feeding guide roller has a guide groove on its outer periphery.

[0011] Preferably, the spacing adjustment device includes a spacing traction block, a spacing traction screw, and a spacing adjustment motor. The spacing adjustment motor is mounted on the rotary device, the spacing traction screw is mounted on the output end of the spacing adjustment motor, and the spacing traction block is mounted on the rotary translation frame.

[0012] Preferably, the pressure diaphragm is a rubber diaphragm.

[0013] Preferably, the pressure flap is a spring steel sheet, and the spring steel sheet is provided with injection holes.

[0014] The beneficial effects of this invention are: The transverse impregnation system includes a transverse trough, an impregnation pressure roller, and several impregnation guide rollers. Carbon fiber bundles are guided down by the impregnation pressure roller and the several impregnation guide rollers and conveyed into the transverse trough. A feeding guide device is installed on the side of the transverse trough away from the feeding system. The carbon fiber bundles pass through the feeding guide device for conveying. As the feeding guide device moves transversely with the transverse trough, it causes the carbon fiber bundles to oscillate on a rotary reference system. The rotary reference system, through a winding action, then weaves the fabric into a web. The feeding guide device ensures the stability of the carbon fiber bundles' direction. The transverse trough is installed on the laying transverse system and moves transversely under the drive of the laying transverse system. The transverse trough is filled with resin. The feeding guide device points towards the rotary reference system, bringing the carbon fiber bundles closer. The impregnation pressure roller and each impregnation guide roller are rotatably installed in the transverse trough. The carbon fiber bundles are conveyed down by the impregnation pressure roller and the several impregnation guide rollers and impregnated into the resin.

[0015] The impregnation pressure roller includes a pressure rotary cylinder, several pressure films, and several pressure flaps. The pressure rotary cylinder is rotatably mounted in a transverse material trough. Several pressure grooves are provided on the outside of the pressure rotary cylinder, and the pressure films are installed in the pressure grooves. Each pressure flap is installed on a corresponding pressure groove and can be opened and closed. Each pressure flap opens and closes the corresponding pressure groove when it opens and closes. A pressure hood is provided inside the pressure rotary cylinder. The pressure hood is connected to the side of the pressure film away from the pressure flaps. After the pressure flaps press on the carbon fiber bundle, they are pressed into the transverse material trough, forcing the resin in the transverse material trough to be extruded and sprayed towards the carbon fiber bundle, thus impregnating the carbon fiber bundle. On the other hand, the pressure hood is connected to an air source through a rotary joint to supply air to the pressure hood. The pressure hood is adapted to the inner wall of the pressure rotary cylinder. The pressure rotary cylinder has a vent hole that communicates with the pressure groove. The pressure hood is rotatably installed inside the pressure rotary cylinder via a bearing. Under its own weight, the pressure hood hangs down naturally. When the vent hole rotates to the position of the pressure hood, the air inside the pressure hood flows to the pressure groove through the vent hole. The pressure hood squeezes the pressure membrane, causing the pressure membrane to deform. The deformed pressure membrane forces the resin in the pressure groove to be squeezed out, so that this part of the resin is sprayed out from the preset spray hole on the pressure flap, forcibly supplying resin to the carbon fiber, so that the carbon fiber is quickly impregnated with resin, preventing the carbon fiber bundles from not being impregnated and preventing gaps and intervals between adjacent carbon fiber bundles, thus ensuring the molding effect.

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 5 As shown, this embodiment provides a carbon fiber weaving machine, including a feeding system 1, a transverse impregnation system 2, a laying transverse system 3, a rotary reference system 4, and a feeding guide device 5. The transverse impregnation system 2 includes a transverse feed trough 21, an impregnation pressure roller 23, and several impregnation guide rollers 22. The carbon fiber bundle is guided by the impregnation pressure roller 23 and several impregnation guide rollers 22 and conveyed into the transverse feed trough 21. The feeding guide device 5 is installed on the side of the transverse feed trough 21 away from the feeding system 1. The carbon fiber filaments are conveyed through the feeding guide device 5. When the feeding guide device 5 moves transversely with the transverse feed trough 21, it causes the carbon fiber bundle to move along the rotary reference system 4. The reference system 4 swings on the quasi-system, and the rotary reference system 4 achieves weaving into a web through a winding action. The feeding guide device 5 is used to ensure the stability of the carbon fiber filament direction. The transverse material trough 21 is installed on the laying transverse system 3. The transverse material trough 21 is moved transversely under the drive of the laying transverse system 3. The transverse material trough 21 is loaded with resin. The feeding guide device 5 points to the rotary reference system 4, so that the carbon fiber filament is close to the rotary reference system 4. The impregnation pressure roller 23 and each impregnation guide roller 22 are rotatably installed in the transverse material trough 21. The carbon fiber filament bundle is guided by the impregnation pressure roller 23 and each impregnation guide roller 22 and conveyed down to be immersed in the resin.

[0023] The impregnation pressure roller 23 includes a pressure rotary cylinder 231, several pressure films 232, and several pressure flaps 233. The pressure rotary cylinder 231 is rotatably installed in the transverse material trough 21. Several pressure grooves 2311 are provided on the outer side of the pressure rotary cylinder 231. The pressure films 232 are installed in the pressure grooves 2311. Each pressure flap 233 is foldably installed on the corresponding pressure groove 2311. Each pressure flap 233 applies corresponding pressure when the corresponding pressure groove 2311 is opened or closed. The opening and closing of the trough 2311 involves a pressure hood 234 inside the pressure rotary cylinder 231. The pressure hood 234 is connected to the side of the pressure membrane 232 away from the pressure flap 233. After the pressure flap 233 presses against the carbon fiber bundle, it is pressed into the transverse material trough 21, forcing the resin in the transverse material trough 21 to be extruded under pressure and sprayed towards the carbon fiber bundle, thus impregnating the carbon fiber bundle. On the other hand, the pressure hood 234 is connected to an air source through a rotary joint to supply air to the pressure hood 234. The pressurization hood 234 is adapted to the inner wall of the pressurization rotary cylinder 231. The pressurization rotary cylinder 231 is provided with a vent 23111 that communicates with the pressurization groove 2311. The pressurization hood 234 is rotatably installed inside the pressurization rotary cylinder 231 via a bearing. The pressurization hood 234 hangs down naturally under its own weight, so that when the vent 23111 rotates to the position of the pressurization hood 234, the air inside the pressurization hood 234 flows to the pressurization groove 231 through the vent 23111. 1. The air filling the pressure hood 234 compresses the pressure membrane 232, causing the pressure membrane 232 to deform. The deformed pressure membrane 232 pressurizes and squeezes out the resin in the pressure groove 2311, causing this part of the resin to be sprayed out from the preset spray hole 2331 on the pressure flap 233, forcibly supplying resin to the carbon fiber, quickly impregnating the carbon fiber with resin, preventing the carbon fiber bundles from not being impregnated, and preventing gaps and intervals between adjacent carbon fiber bundles, thus ensuring the molding effect.

[0024] Specifically, the feeding system 1 includes a feeding frame 11 and a feeding cylinder 12. The feeding cylinder 12 is rotatably mounted on the feeding frame 11. The feeding cylinder 12 is wound with carbon fiber filaments, and the unwinding of the feeding cylinder 12 realizes the continuous supply of carbon fiber filaments.

[0025] Specifically, the laying transverse system 3 includes a transverse frame 31, a transverse motor 32, a transverse slider 33, a transverse screw 34, and a transverse rail 35. The transverse rail 35 is mounted on the transverse frame 31, and the direction of the transverse rail 35 is consistent with the direction of the rotary reference system 4. The transverse slider 33 is slidably mounted on the transverse rail 35, and the transverse screw 34 is rotatably mounted on the transverse frame 31. The transverse motor 32 is mounted on the transverse frame 31, and the transverse screw 34 is mounted on the output end of the transverse motor 32. The transverse material trough 21 is mounted on the transverse slider 33. The transverse motor 32 drives the transverse slider 33 to move transversely, which in turn drives the transverse material trough 21 to move transversely, so that the feeding guide device 5 can move transversely and the carbon fiber bundle can be wound and distributed on the feeding cylinder 12.

[0026] Specifically, the rotary reference system 4 includes a rotary device 41, a rotary translation frame 42, and a spacing adjustment device 43. The rotary translation frame 42 is slidably installed on the side of the rotary device 41. A three-jaw chuck is provided on both the side of the rotary device 41 near the rotary translation frame 42 and the side of the rotary translation frame 42 near the rotary device 41. A winding reference cylinder 44 is clamped between the rotary device 41 and the rotary translation frame 42 through the three-jaw chuck. Carbon fiber filaments are wound on the winding reference cylinder 44, making the carbon fiber filaments into a cylindrical shape. The cylindrical carbon fiber filaments can be cut along the generatrix to become fabric. The spacing adjustment device 43 is installed between the rotary device 41 and the rotary translation frame 42. The spacing adjustment device 43 adjusts the distance between the rotary device 41 and the rotary translation frame 42, thereby adapting to winding reference cylinders 44 of different widths and adapting to the production of fabrics of different widths.

[0027] Specifically, the feeding guide device 5 includes several feeding guide rollers 51, and each feeding guide roller 51 has a guide groove on its outer periphery to ensure a stable supply of carbon fiber filaments.

[0028] Specifically, the spacing adjustment device 43 includes a spacing traction block 431, a spacing traction screw 432, and a spacing adjustment motor 433. The spacing adjustment motor 433 is mounted on the rotary device 41, the spacing traction screw 432 is mounted on the output end of the spacing adjustment motor 433, and the spacing traction block 431 is mounted on the rotary translation frame 42. The spacing adjustment motor 433 drives the spacing traction block 431 to move, thereby driving the rotary translation frame 42 to translate.

[0029] Specifically, the pressure diaphragm 232 is a rubber diaphragm, which makes it easy to change the volume of the pressure tank 2311.

[0030] Specifically, the pressure flap 233 is a spring steel sheet, which is installed on the pressure rotary cylinder 231 by screws. The periphery of the spring steel sheet is bent toward the pressure groove 2311, so that the outline of the spring steel sheet is adapted to the pressure groove 2311. The spring steel sheet is provided with injection holes 2331 to force resin to be supplied to the carbon fiber, so as to impregnate the carbon fiber with resin and ensure the molding effect.
