Technical Field

[0001] This utility model relates to the field of composite material preparation technology, and in particular to a sizing device for carbon fiber processing. Background Technology

[0002] Carbon fiber is widely used in many fields due to its advantages such as high strength and lightweight. However, its surface is highly inert, easily worn during processing, and has poor bonding with the matrix material. In order to improve its weaving performance and the interfacial bonding of composite materials, it is necessary to coat it with special sizing agent through sizing device. This is the research and development background of sizing device for carbon fiber processing.

[0003] In the existing technology, before carbon fiber is wound into a cylinder, it needs to be wetted, impregnated with slurry, and dried before it can be wound into a cylinder for storage. In the existing technology, a set of transfer rollers is set up to transport the carbon fiber to a V-cylinder filled with slurry, and the two or more sets of transfer rollers inside the V-cylinder are used to transfer the material, achieving continuous operation of feeding, impregnation and rapid discharge. However, the existing V-cylinder cannot meet the material state, model requirements and sizing processing needs of the carbon fiber to be sized.

[0004] Therefore, a sizing device for carbon fiber processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a sizing device for carbon fiber processing that can solve the problem of poor adaptability of existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sizing device for carbon fiber processing, comprising an impregnation tank, with transfer roller sets fixedly connected to both sides of the top of the impregnation tank, a flexible adaptation mechanism movably connected to the inner side of the impregnation tank, and an anti-seepage auxiliary component movably connected to the inner side of the impregnation tank. The flexible adaptation mechanism includes two first supports, which are slidably connected to both sides of the bottom of the impregnation tank. A support inclined plate is rotatably connected to the outer side of the first supports, and a second support is rotatably connected to the other end of each of the two support inclined plates. The two second supports are slidably connected to both sides of the inner side of the impregnation tank. A support frame is fixedly connected to the top of the first supports, and a transfer roller is rotatably connected to the inner side of the support frame. An adjustment component is movably connected to the opposite side of each of the two first supports.

[0007] Preferably, the anti-seepage auxiliary component includes two filling blocks, which are slidably connected to both sides of the inner side of the immersion tank, and the two filling blocks are respectively arranged on opposite sides of the two first supports.

[0008] Preferably, telescopic rods are fixedly connected to opposite sides of the two filling blocks, and a first compression spring is fixedly connected to the outer side of the telescopic rods. Support plates are fixedly connected to opposite sides of the two telescopic rods.

[0009] Preferably, support rods are fixedly connected to both sides of the impregnation tank, telescopic columns are fixedly connected to the bottom of the support rods, second compression springs are fixedly connected to the outer side of the telescopic columns, and a sealing baffle is fixedly connected to the bottom of the telescopic columns. The sealing baffle is located on the top of the filling block.

[0010] Preferably, the adjustment component includes a servo motor, which is fixedly connected to the bottom of the immersion tank, and a rotating block is fixedly connected to the output end of the servo motor.

[0013] Preferably, a replenishment tank is fixedly connected to the rear side of the impregnation tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application solves the problem that existing V-cylinders, due to their fixed angle and non-adjustable transfer roller position, cannot adapt to the state, type, and processing requirements of carbon fiber materials and are difficult to adjust tension by setting up a flexible adaptation mechanism. It sets up an adjustable V-cylinder consisting of an impregnation tank and two sets of inclined surfaces with supporting inclined plates. With the help of a servo motor-driven linkage structure, the sliding of the first and second supports and the slope of the supporting inclined plates are adjusted to achieve flexible adjustment of the transfer roller spacing and V-cylinder angle, thereby meeting different adaptation requirements and achieving tension adjustment.

[0016] 2. This application solves the potential problems of grout entering through rotating gaps in the excess space at the bottom of the slope, causing waste, residual deterioration, and possible leakage to the outside by setting up anti-seepage auxiliary components. By setting up filling blocks, when the slope of the supporting slope is gentle, the excess space is filled to prevent grout from entering. When the slope increases, the guide slope formed by the gap inlet and outlet and the slope of the block allows the seeping grout to flow back. On extremely steep slopes, the sealing baffle supported by the telescopic column fits into the slope of the block to block the opening and prevent leakage. When retracted, the block is reset by the telescopic cylinder and the compression spring, and the compression spring stores energy, thereby avoiding grout waste, residual deterioration, and leakage to the outside.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A sizing device for carbon fiber processing includes an impregnation tank 1. Transfer roller sets 2 are fixedly connected to both sides of the top of the impregnation tank 1. A flexible adaptation mechanism 3 is movably connected to the inner side of the impregnation tank 1. An anti-seepage auxiliary component 4 is movably connected to the inner side of the impregnation tank 1. The flexible adaptation mechanism 3 includes two first supports 31, which are slidably connected to both sides of the bottom of the impregnation tank 1. Supporting inclined plates 32 are rotatably connected to the outer sides of the first supports 31, and second supports 33 are rotatably connected to the other ends of the two supporting inclined plates 32. The two second supports 33 are slidably connected to both sides of the inner side of the impregnation tank 1. A support frame 34 is fixedly connected to the top of the first supports 31, and a transfer roller 35 is rotatably connected to the inner side of the support frame 34. An adjustment component 36 is movably connected to the opposite side of each of the two first supports 31.

[0026] In this embodiment: instead of using a traditional customized V-cylinder, the impregnation tank 1 is used as the main body for carrying the slurry. The inner sides of the impregnation tank 1 are provided with two sets of inclined surfaces, each consisting of a first support 31, a second support 33, and a support inclined plate 32 rotatably connected between them. The two sets of support inclined plates 32, together with the internal capacity space of the impregnation tank 1, form an adjustable V-cylinder. The top of the two first supports 31 is fixedly connected to a support frame 34 that carries the transfer rollers 35. When adaptation adjustment is required, the slope of the support inclined plate 32 can be increased when the distance between the two transfer rollers 35 increases, and decreased when the distance decreases. This solves the problem of poor adaptability caused by the non-adjustable bottom angle of the traditional V-cylinder and the fixed position of the internal transfer rollers 35.

[0027] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the anti-seepage auxiliary component 4 includes two filling blocks 41, which are slidably connected to both sides of the inner side of the immersion tank 1, and the two filling blocks 41 are respectively set on opposite sides of the two first supports 31.

[0028] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, telescopic cylinders 42 are fixedly connected to opposite sides of the two filling blocks 41, and a first compression spring 43 is fixedly connected to the outer side of the telescopic cylinders 42. Support plates 44 are fixedly connected to opposite sides of the two telescopic cylinders 42.

[0029] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, support rods 45 are fixedly connected to both sides of the impregnation tank 1. Telescopic columns 46 are fixedly connected to the bottom of the support rods 45. A second compression spring 47 is fixedly connected to the outside of the telescopic columns 46. A sealing baffle 48 is fixedly connected to the bottom of the telescopic columns 46. The sealing baffle 48 is set on the top of the filling block 41.

[0030] In this embodiment: The bottom of the inclined plane formed by the first support 31, the second support 33, and the supporting inclined plate 32 has excess space in the non-immersion area of ​​the impregnation tank 1. Slurry may enter this space through the rotation gap between the supporting inclined plate 32 and the first and second supports 31 and 33, causing waste and residual deterioration. Therefore, a filling block 41 is installed in this space. When the supporting inclined plate 32 is at its extreme gentle slope, the filling block 41 fills the entire excess space, preventing slurry from entering even if it crosses the gap. When the slope of the supporting inclined plate 32 is increased, the first support 31 moves outward, pushing the filling block 41 to slide towards the outside of the impregnation tank 1. At this time, the filling block 41 cannot fill the excess space, but the entrance and exit of the rotation gap, the excess space, and the inclined plane of the filling block 41 form a guideable inclined slope, which can guide the infiltrated slurry back to the effective space. When the supporting inclined plate 32 is at an extremely steep slope, the filling block 41 fills the excess space. An opening that leaks outwards is formed between the block 41 and the immersion tank 1. Normally, the top of this opening is supported by a telescopic column 46 and a sealing baffle 48. The cut end of the sealing baffle 48 fits against the inclined surface of the filling block 41. When the inclined surface of the filling block 41 moves to the outside of the immersion tank 1 and creates an opening, the sealing baffle 48 will quickly spring downwards to block the opening and fit against the inclined surface of the filling block 41, preventing leakage into excess space and the outside of the immersion tank 1, because the second compression spring 47 inside the telescopic column 46 is normally stored. In addition, when the filling block 41 slides outwards, it will press the telescopic cylinder 42 and the outer first compression spring 43 between it and the top support plate 44 of the support base 5. When it is retracted, the telescopic cylinder 42 and the inner first compression spring 43 will drive the filling block 41 to move back into the immersion tank 1 and reset, while squeezing the top sealing baffle 48 and the telescopic column 46 and the inner second compression spring 47 between it and the support rod 45 to re-store elastic energy.

[0031] Specifically, such as Figure 3 As shown, the adjustment component 36 includes a servo motor 3601, which is fixedly connected to the bottom of the immersion tank 1, and a rotating block 3602 is fixedly connected to the output end of the servo motor 3601.

[0032] Specifically, such as Figure 3 As shown, both sides of the rotating block 3602 are rotatably connected to a linkage rod 3603, and the other ends of the two linkage rods 3603 are respectively rotatably connected to the opposite side of the two first supports 31.

[0033] In this embodiment: by starting the servo motor 3601 at the bottom of the impregnation tank 1, the axis of the rotating block 3602 at its output end is rotated, causing the linkage rods 3603 connected to both sides of the rotating block 3602 to rotate and pull, generating a push force from the center to both sides on the two sets of first supports 31. The first supports 31 slide towards the side closer to the inner wall of the impregnation tank 1 under the push of the linkage rods 3603. Through the rotation and compression of the support inclined plate 32, the second support 33 at the other end slides upward along the inner walls on both sides of the impregnation tank 1. Since the top of the first support 31 carries the transfer roller 35, the two transfer rollers 35 move closer to the inner wall and increase the distance. When the servo motor 3601 drives in the reverse direction, the linkage rods 3603 pull the two first supports 31 inward at the same time, performing the above-mentioned reverse linkage.

[0034] Specifically, such as Figure 1 As shown, a support base 5 is fixedly connected to the bottom of the support plate 44, and the support base 5 is fixedly connected to the bottom of the immersion tank 1.

[0035] Specifically, such as Figure 1 As shown, a replenishment tank 6 is fixedly connected to the rear side of the immersion tank 1.

[0036] In this embodiment: the support base 5 can support the overall structure, and the replenishment tank 6 can replenish the slurry.

[0037] Working principle: Before winding carbon fiber into a cylinder, it needs to be impregnated with slurry after wetting and then dried before it can be wound into a cylinder for storage. In the existing technology, the carbon fiber is transported to the V-cylinder filled with slurry by setting up a transfer roller group 2, and the transfer is carried out by two or more sets of transfer rollers 35 inside the V-cylinder to achieve continuous operation of feeding impregnation and rapid discharge. However, the existing V-cylinder cannot adjust the included angle of the V-cylinder and the position of the transfer rollers 35 according to the material state, model requirements and sizing processing requirements of the carbon fiber to be sized, so as to achieve the effect of adaptability and tension adjustment. In order to avoid the above situation, the traditional customized V-cylinder is no longer used. Instead, a slurry carrying body composed of an impregnation tank 1 is set up. On both sides of the inner side of the impregnation tank 1, a first support is set up. The first supports 31 and 33, along with the supporting inclined plate 32 rotatably connected between them, form two sets of inclined surfaces. These two sets of supporting inclined plates 32, in conjunction with the internal capacity space of the impregnation tank 1, form an adjustable V-cylinder. A support frame 34 for carrying the transfer roller 35 is fixedly connected to the top of the two first supports 31. When adaptation adjustment is required, the servo motor 3601 located at the bottom of the impregnation tank 1 is activated, causing the rotating block 3602 located at the output end of the servo motor 3601 to rotate axially. This drives the linkage rods 3603 rotatably connected on both sides to generate rotational traction, causing them to simultaneously generate a pushing force from the center to both sides on the two sets of first supports 31. Under the push of the linkage rods 3603, the first supports 31 simultaneously slide towards the side closer to the inner wall of the impregnation tank 1. The second support 33 slides upward along the inner walls of the immersion tank 1 by the rotation and compression of the supporting inclined plate 32. The top of the first support 31 carries the transfer roller 35, so the two transfer rollers 35 move closer to the inner wall to increase the distance. When the servo motor 3601 drives in the reverse direction, the linkage rod 3603 pulls the two first supports 31 inward at the same time and performs the above linkage in the reverse direction. In summary, when the distance between the two transfer rollers 35 increases, the slope of the supporting inclined plate 32 increases, and when the distance between the two transfer rollers 35 decreases, the slope of the supporting inclined plate 32 decreases. This solves the problem of poor adaptability caused by the inability to adjust the included angle at the bottom of the traditional V cylinder and the fixed position of the internal transfer roller 35. Secondly, although the above optimization has improved adaptability, in the first The bottom of the inclined plane formed by the first support 31, the second support 33, and the supporting inclined plate 32 creates excess space in the non-immersion area of ​​the impregnation tank 1. However, slurry may enter this space through the rotation gap between the supporting inclined plate 32 and the first and second supports 31 and 33, resulting in waste and residual deterioration. A filling block 41 is installed inside this space. At the extreme gentle slope of the supporting inclined plate 32, the filling block 41 fills the excess space, ensuring that even if the slurry crosses the gap, it cannot enter the excess space. During the adjustment of the slope of the supporting inclined plate 32, the first support 31 moves outward and pushes the filling block 41, causing it to slide outward from the impregnation tank 1. At this time, the filling block 41 cannot fill the excess space.However, the entrance and exit of the rotating gap, the excess space, and the inclined surface of the filling block 41 form a guideable slope, thus guiding the infiltrated slurry to flow back into the effective space. At the extremely steep slope of the supporting inclined plate 32, an opening for outward leakage will form between the filling block 41 and the impregnation tank 1. To avoid this, a sealing baffle 48 supported by a telescopic column 46 is normally installed at the top of this opening. The cut of this baffle fits against the inclined surface of the filling block 41. When the inclined surface of the filling block 41 moves to the outside of the impregnation tank 1, the opening is created. Since the second compression spring 47 inside the telescopic column 46 is in a normally stored state, after moving to the inclined surface, the sealing baffle... 48 will be quickly bounced downwards to block the opening and conform to the inclined surface of the filling block 41, thereby preventing leakage into excess space and the outside of the impregnation tank 1. When the filling block 41 slides outwards, it will press the telescopic cylinder 42 and its outer first compression spring 43 between itself and the top support plate 44 of the support platform 5. When retracted, the telescopic cylinder 42 and its inner first compression spring 43 will quickly drive the filling block 41 to move back into the impregnation tank 1, simultaneously squeezing the top sealing baffle 48 and the telescopic column 46 between itself and the support rod 45, as well as its inner second compression spring 47, causing it to regenerate elastic energy. In summary, this optimizes the sizing device for carbon fiber processing.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
