Description

Technical Field

[0001] This utility model relates to the field of resin impregnation auxiliary technology for carbon fiber composite materials, specifically to a resin impregnation auxiliary device for carbon fiber composite materials. Background Technology

[0002] Resin impregnation of carbon fiber composites refers to the process of placing carbon fibers or their fabrics in a liquid resin matrix and using processes such as impregnation, brushing, vacuum infusion, and molding to allow the resin to fully penetrate into the interior of the carbon fiber bundles and the gaps between the fibers, ultimately forming an integral structure in which the fibers and resin are tightly bonded.

[0003] In the resin impregnation process of carbon fiber composites, a resin mixer is used as an auxiliary tool. The resin mixer is mainly used in the resin pretreatment stage before impregnation. Since the resin matrix often needs to be mixed with curing agents, accelerators, fillers or functional additives according to performance requirements, the resin mixer uses mechanical stirring to fully mix and disperse the resin with various additives to form a stable resin system. This ensures that the carbon fiber can fully contact and bond with the resin with uniform properties during subsequent impregnation, avoiding the decline in the mechanical properties of the composite material due to uneven resin composition. The resin often needs to be mixed with high-density fillers or high-viscosity additives. The blade structure of ordinary mixers can easily cause materials to accumulate at the bottom, edge or blade blind area of ​​the mixing tank, resulting in "agglomeration" and "layering". Especially for high-viscosity resins, it is even more difficult to ensure the uniformity of mixing. Therefore, we propose a resin impregnation auxiliary device for carbon fiber composites. Utility Model Content

[0004] The purpose of this invention is to provide a resin impregnation auxiliary device for carbon fiber composite materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a resin impregnation auxiliary device for carbon fiber composite materials, comprising a base, a column fixedly connected to the surface of the base, a stirrer mounted on the surface of the column, a tank placed on the surface of the base, a stirring structure provided on the surface of the stirrer, the stirring structure comprising a stirring rod, the stirring rod fixedly connected to the surface of the stirrer, a plurality of drive gears fixedly connected to the surface of the stirring rod, a plurality of supports fixedly connected to the arc surface of the stirring rod, drive rods rotatably connected to both sides of the supports, driven gears fixedly connected to the ends of two drive rods that are close to each other, the driven gears meshing with the drive gears, and a plurality of stirring blades fixedly connected to the arc surface of the drive rod.

[0006] The effect achieved by the above components is as follows: by setting up a stirring structure, multi-dimensional stirring is achieved to achieve uniform mixing of resin and additives, and efficient mixing of resin and additives is achieved, providing a resin system with uniform performance for the subsequent carbon fiber impregnation process.

[0007] Preferably, the surfaces of the drive gear disk and the driven gear disk are covered with protective covers, and the protective covers are fixedly connected to the surface of the bracket.

[0008] The effect achieved by the above components is that the protective cover is placed on the surface of the drive gear and the driven gear to prevent resin or additives from entering the meshing area of ​​the gear and affecting the transmission, thus ensuring the stability of power transmission.

[0009] Preferably, a plurality of extension rods are fixedly connected to the arc surface of the stirring rod, and a scraper is fixedly connected to the end of the extension rod away from the stirring rod.

[0010] The effect achieved by the above components is that when the stirring rod rotates, the extended rod of its arc surface drives the scraper to rotate along the inner wall of the tank, which can scrape off the material accumulated on the tank wall and avoid material residue and local solidification.

[0011] Preferably, the surface of the stirring blade has rectangular holes.

[0012] The effects achieved by the above components are as follows: the rectangular holes on the surface of the stirring blades can reduce stirring resistance, and at the same time, they can create turbulence when the material passes through the holes, thereby enhancing the shearing and mixing effect between the materials.

[0013] Preferably, the surface of the base is provided with a limiting structure, the limiting structure including a fixing plate, the fixing plate being fixedly connected to the surface of the base, the surface of the fixing plate being rotatably connected to a bidirectional screw, the surface of the bidirectional screw being threadedly connected to two drive plates, the two drive plates being threadedly connected to both sides of the fixing plate respectively, and clamping plates being fixedly connected to the side of the two drive plates that are close to each other.

[0014] The effect achieved by the above components is that by setting a limiting structure, it is easy to use two clamps to hold the tank from both sides, thereby firmly holding the tank and ensuring the safety and reliability of the stirring process.

[0015] Preferably, an extension plate is fixedly connected to one side of the drive plate, and a guide rod slides through the surface of the extension plate, the guide rod being fixedly connected to the surface of the fixed plate.

[0016] The effect achieved by the above components is that the movement of the drive plate will cause the extension plate to slide along the surface of the guide rod, and the guide rod will limit the movement path of the extension plate, thereby preventing the clamping plate from rotating during movement.

[0017] Preferably, an anti-slip strip is fixedly connected to one side of the clamp.

[0018] The effect achieved by the above components is that the anti-slip strips on the inner side of the clamping plate increase the friction with the surface of the tank, preventing the tank from shifting or tipping over due to vibration or stirring force during the stirring process, and further improving the stability of the device operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention features a stirring structure that allows the driving toothed disc on the surface of the stirring rod to rotate synchronously. Since the driving toothed disc meshes with the driven toothed disc, when the driving toothed disc rotates, it drives the driven toothed disc and the driving rod fixed to it to rotate on the support. At this time, the stirring rod itself rotates to form primary stirring, and the driving rod rotates around its own axis to form secondary stirring. The combination of these two elements achieves multi-dimensional stirring. The stirring blades on the driving rod rotate with the driving rod, stirring the materials in the middle and edges of the tank, achieving efficient mixing of resin and additives, and providing a uniform resin system for the subsequent carbon fiber impregnation process.

[0021] By setting a limiting structure, the bidirectional screw can be rotated. The bidirectional screw rotates within the fixed plate. The rotation of the bidirectional screw will drive the two drive plates to move closer to each other through the thread. When the drive plates move closer, the clamping plate on one side moves synchronously until the clamping plate is in close contact with the outer wall of the tank, thus completing the limiting and fixing of the tank and ensuring the safety and reliability of the stirring process.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-2 This utility model provides a technical solution: an auxiliary device for resin impregnation of carbon fiber composite materials, including a base 1, a column 2 fixedly connected to the surface of the base 1, a stirrer 3 mounted on the surface of the column 2, a tank 4 placed on the surface of the base 1, and a stirring structure 5 provided on the surface of the stirrer 3. By setting the stirring structure 5, multi-dimensional stirring is achieved to uniformly mix the resin and additives, realizing efficient mixing of the resin and additives, and providing a resin system with uniform performance for subsequent carbon fiber impregnation processes. The surface of the base 1 is provided with a limiting structure 6, which facilitates the use of two clamping plates 64 to clamp the tank 4 from both sides, thereby firmly clamping the tank 4 and ensuring the safety and reliability of the stirring process.

[0031] Reference Figure 3 and Figure 4As shown in this embodiment: the stirring structure 5 includes a stirring rod 501, which is fixedly connected to the surface of the stirrer 3. Several drive gear discs 502 are fixedly connected to the surface of the stirring rod 501. Several supports 503 are fixedly connected to the arc surface of the stirring rod 501. Drive rods 504 are rotatably connected to both sides of each support 503. Driven gear discs 505 are fixedly connected to the ends of two drive rods 504 that are close to each other. The driven gear discs 505 mesh with the drive gear discs 502. Several stirring blades 506 are fixedly connected to the arc surface of the drive rods 504. Protective covers 507 are fitted over the surfaces of the drive gear discs 502 and the driven gear discs 505. The protective covers 507 are fixedly connected to the surface of the supports 503. The protective covers 507 prevent resin or additives from entering the meshing area of ​​the gear discs and affecting the transmission, ensuring the stability of power transmission. Several extension rods 508 are fixedly connected to the arc surface of the stirring rod 501. A scraper 509 is fixedly connected to the end of the extension rod 508 away from the stirring rod 501. When the stirring rod 501 rotates, the extension rods 508 on its arc surface drive the scraper 509 to rotate along the inner wall of the tank 4, which can scrape off the material accumulated on the tank wall and avoid material residue and local solidification. The surface of the stirring blade 506 has rectangular holes 510. The rectangular holes 510 on the surface of the stirring blade 506 can reduce the stirring resistance and at the same time make the material form turbulence when passing through the holes, enhancing the shearing and mixing effect between materials.

[0032] Reference Figure 5 and Figure 6 As shown, specifically, the limiting structure 6 includes a fixed plate 61, which is fixedly connected to the surface of the base 1. A bidirectional screw 62 is rotatably connected to the surface of the fixed plate 61, and two drive plates 63 are threadedly connected to the surface of the bidirectional screw 62. The two drive plates 63 are respectively threaded to both sides of the fixed plate 61, and clamping plates 64 are fixedly connected to the side of the two drive plates 63 that are close to each other. An extension plate 65 is fixedly connected to one side of the drive plate 63, and a guide rod 66 slides through the surface of the extension plate 65. The guide rod 66 is fixedly connected to the surface of the fixed plate 61. When the drive plate 63 moves, it will cause the extension plate 65 to slide along the surface of the guide rod 66. The guide rod 66 restricts the movement path of the extension plate 65, thereby preventing the clamping plate 64 from rotating during movement. An anti-slip strip 67 is fixedly connected to one side of the clamping plate 64. The anti-slip strip 67 on the inner side of the clamping plate 64 increases the friction with the surface of the tank 4, preventing the tank 4 from shifting or tipping over due to vibration or stirring force during the stirring process, and further improving the stability of the device operation.

[0033] Working principle: When resin needs to be stirred, the resin raw material is first poured into the tank 4, and then the tank 4 is placed on the surface of the base 1, so that the stirring rod 501 is inserted into the tank 4. Then, the stirrer 3 drives the stirring rod 501 to rotate, and the driving toothed disc 502 on the surface of the stirring rod 501 rotates synchronously with it. Since the driving toothed disc 502 and the driven toothed disc 505 mesh with each other, when the driving toothed disc 502 rotates, it will drive the driven toothed disc 505 and the driving rod 504 fixed thereto to rotate on the bracket 503. At this time, the stirring rod 501 rotates by itself to form primary stirring, and the driving rod 504 rotates around its own axis to form secondary stirring. The combination of the two achieves multi-dimensional stirring action. The blade 506 rotates with the drive rod 504, stirring the material in the middle and edge of the tank. The rectangular holes 510 on the surface of the blade 506 reduce stirring resistance and create turbulence when the material passes through the holes, enhancing the shearing and mixing effect between materials. This effectively solves the problems of "agglomeration" and "layering" of high-viscosity resins or high-density fillers. When the stirring rod 501 rotates, its arc-shaped extension rod 508 drives the scraper 509 to rotate along the inner wall of the tank 4, which can scrape off the material accumulated on the tank wall, avoiding material residue and local solidification. The protective cover 507 is fitted on the surface of the drive gear 502 and the driven gear 505 to prevent resin or additives from entering the meshing area of ​​the gear and affecting the transmission, ensuring the stability of power transmission.

[0034] When it is necessary to fix the can 4, first place the can 4 on the surface of the base 1, and then rotate the bidirectional screw 62. The rotation of the bidirectional screw 62 will rotate within the fixing plate 61. The rotation of the bidirectional screw 62 will drive the two drive plates 63 to move closer to each other through the thread. The movement of the drive plates 63 will drive the extension plate 65 to slide along the surface of the guide rod 66. The guide rod 66 will limit the movement path of the extension plate 65, thereby preventing the clamping plate 64 from rotating when moving. When the drive plate 63 moves closer, the clamping plate 64 on one side moves synchronously until the clamping plate 64 is in close contact with the outer wall of the can 4, thus completing the limiting and fixing of the can 4. The anti-slip strip 67 on the inner side of the clamping plate 64 increases the friction with the surface of the can 4, preventing the can 4 from shifting or tipping over due to vibration or stirring force during the stirring process, and further improving the stability of the device operation.
