Description

Technical Field

[0001] This utility model relates to the technical field of vacuum sizing equipment, and in particular to a high-efficiency sealing device for vacuum sizing of carbon fiber cloth. Background Technology

[0002] In recent years, the application of carbon fiber has developed rapidly and has been widely used in many fields such as aerospace, automobiles, energy, construction, and sports equipment. In carbon fiber carbonization, sizing is a very important process. The purpose of sizing is to give carbon fiber bundles the properties of bundles, wear resistance, and water absorption resistance. Vacuum sizing can allow the sizing liquid to penetrate into the interior of the carbon fiber bundles better and improve the sizing quality.

[0003] Existing carbon fiber sizing equipment has a short sizing time, making it difficult for the sizing liquid to fully bond with the carbon fiber, which can easily lead to uneven sizing.

[0004] The existing patent (publication number: CN216006274U) discloses a sizing device for processing carbon fiber filament bundles, which increases the number of sizing rollers and extends the time when the carbon fiber filament bundles are immersed in the sizing solution, making it easier for the sizing solution to combine with the carbon fiber and improving the sizing efficiency. This utility model has the advantages of reasonable design and low manufacturing cost.

[0005] To address the aforementioned issues, existing patents offer solutions, but their sealing performance is inadequate. In actual production, the lack of an effective sealing structure allows outside air to easily enter the container, disrupting its vacuum and impairing the penetration of the sizing solution. Consequently, the sizing solution cannot penetrate evenly and deeply into each carbon fiber filament as expected, resulting in some areas of carbon fibers not being able to fully contact the sizing solution. This affects the sizing effect of the carbon fiber cloth and reduces the practicality of the device.

[0006] To address this, a high-efficiency sealing device for vacuum sizing of carbon fiber cloth is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency sealing device for vacuum sizing of carbon fiber cloth. This device can solve the problem of poor sealing performance of existing sizing equipment. In actual production, due to the lack of an effective sealing structure, outside air can easily enter the container, damaging its vacuum level. This results in poor penetration of the sizing liquid, preventing it from penetrating evenly and deeply into each carbon fiber filament as expected. Consequently, some areas of the carbon fiber cannot fully contact the sizing liquid, affecting the sizing effect of the carbon fiber cloth and reducing the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency sealing device for vacuum sizing of carbon fiber cloth, comprising a box body, a sizing component fixedly connected inside the box body, and a sealing component fixedly connected to the front and rear sides of the box body.

A pressing roller is rotatably connected inside the connecting bracket.

[0010] Preferably, a storage box is fixedly connected to one side of each of the two connecting plates, and a rubber roller is rotatably connected inside the storage box. Rubber sealing blocks are fixedly connected to the front and rear sides of the storage box.

[0011] Preferably, a movable rod is fixedly connected to the side of each connecting plate away from the storage box, and the movable rod extends to the outside of the fixed square tube and is fixedly connected to a handle on the side away from the connecting plate.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A high-efficiency sealing device for vacuum sizing of carbon fiber cloth includes a housing 1. A sizing component 2 is fixedly connected inside the housing 1, and a sealing component 3 is fixedly connected to the front and rear sides of the housing 1. The sealing component 3 includes a fixed square tube 301. A connecting plate 302 is movably connected to the top and bottom inside the fixed square tube 301, and several springs 303 are fixedly connected to both sides of opposite sides of the two connecting plates 302.

[0029] The sizing assembly 2 includes a liquid storage tank 201. Fixing blocks 202 are fixedly connected to the front and rear sides of the top two sides of the liquid storage tank 201. A fixing bracket 203 is fixedly connected to the top of the liquid storage tank 201. A limiting roller 204 is rotatably connected between the two fixing blocks 202 on opposite sides. A coating roller 205 is provided at the bottom of the limiting roller 204. A cylinder 206 is fixedly connected to the top of the inner wall of the fixing bracket 203. A connecting bracket 207 is fixedly connected to the bottom of the cylinder 206. A pressing roller 208 is rotatably connected inside the connecting bracket 207.

[0030] In this embodiment: by pulling the handle 308, the moving rod 307 moves smoothly, simultaneously moving the connecting plate 302 smoothly and compressing the spring 303, releasing the restrictive effect of the sealing component 3, allowing the carbon fiber cloth to smoothly enter the housing 1. Simultaneously, under the action of the spring 303, the connecting plate 302 smoothly returns to its original position, thereby causing the rubber sealing block 306 and rubber roller 305 to return to their original positions and contact the carbon fiber cloth. This restricts the movement of the carbon fiber cloth while blocking external air, thus maintaining a vacuum environment inside the housing 1, ensuring the sizing effect, and improving the ease of use of the sealing component 3. Then, through... The combined use of the limiting roller 204 and the coating roller 205 allows the carbon fiber cloth to pass smoothly through them. This not only restricts the movement of the carbon fiber cloth but also coats its surface with slurry, preventing uneven sizing and ensuring product quality. This improves the sizing effect of the carbon fiber cloth. Furthermore, under the action of the cylinder 206, the connecting bracket 207 can be moved smoothly, simultaneously driving the pressing roller 208 to move smoothly. This, in turn, immerses the carbon fiber cloth into the interior of the liquid storage tank 201, allowing the carbon fiber cloth to fully contact the slurry and thus enabling the slurry to fully penetrate the interior of the carbon fiber cloth. This improves the ease of use of the sizing component 2.

[0031] Specifically, such as Figure 4As shown, storage boxes 304 are fixedly connected to the opposite sides of the two connecting plates 302, and rubber rollers 305 are rotatably connected inside the storage boxes 304. Rubber sealing blocks 306 are fixedly connected to the front and rear sides of the storage boxes 304.

[0032] Specifically, such as Figure 4 As shown, each of the two connecting plates 302 is fixedly connected to a movable rod 307 on the side away from the storage box 304, and the movable rod 307 extends to the outside of the fixed square tube 301 on the side away from the connecting plate 302 and is fixedly connected to a handle 308.

[0033] Specifically, such as Figure 4 As shown, the top and bottom of the inner wall of the fixed square tube 301 are provided with connecting grooves 4 for use with the connecting plate 302, and the end of the spring 303 away from the connecting plate 302 is fixedly connected to the inner wall of the connecting groove 4.

[0034] In this embodiment: the connecting plate 302 and the connecting groove 4 work together to allow the connecting plate 302 to move smoothly under the restriction of the connecting groove 4 and compress the spring 303, thereby releasing the restriction effect of the sealing component 3 and allowing the carbon fiber cloth to enter the interior of the housing 1 smoothly. Under the action of the spring 303, the connecting plate 302 can be driven to return smoothly to its original position, so that the rubber roller 305 and the rubber sealing block 306 come into contact with the carbon fiber cloth. This can restrict the carbon fiber cloth of a specific specification, not only restricting the movement of the carbon fiber cloth, but also blocking the outside air, thereby maintaining the vacuum environment inside the housing 1, thus ensuring the sizing effect and improving the ease of use of the sealing component 3.

[0035] Specifically, such as Figure 5 As shown, stirring blades 5 are rotatably connected to the front and rear sides of the inner wall of the storage tank 201, and rotating motors 6 are fixedly connected to opposite sides of the two stirring blades 5.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, a vacuum machine 7 is fixedly connected to the top of the box 1, and an electric exhaust valve 8 is fixedly connected to the bottom right side of the box 1. A conveying pipe 9 is fixedly connected to the front side of the vacuum machine 7, and the side of the conveying pipe 9 away from the vacuum machine 7 extends into the interior of the box 1 and is fixedly connected to a suction plate 10.

[0037] In this embodiment: by rotating the motor 6, the stirring blade 5 can be driven to rotate smoothly, thereby driving the slurry inside the storage tank 201 to flow, preventing slurry sedimentation, ensuring the uniformity of the slurry, and improving the slurry's performance. Then, under the action of the vacuum machine 7, the air inside the box 1 is evenly extracted through the conveying pipe 9 and the suction plate 10, which can create a vacuum environment inside the box 1. At the same time, under the action of the electric exhaust valve 8, outside air can enter the inside of the box 1, which can increase the air pressure inside the box 1, thereby creating a suitable sizing environment for the carbon fiber cloth and improving the sizing effect of the carbon fiber cloth.

[0038] Specifically, such as Figure 3 As shown, a movable door 11 is movably connected to the right side of the housing 1, and a double-layer flexible sealing ring 12 is fixedly connected to the side of the movable door 11 near the housing 1. A controller 13 is fixedly connected to the right side of the movable door 11, and the controller 13 is electrically connected to the sizing assembly 2, the vacuum machine 7 and the electric exhaust valve 8.

[0039] Specifically, such as Figure 2 , Figure 3 As shown, a pressure detector 14 is fixedly connected to the front side of the right side of the inner wall of the housing 1, and the pressure detector 14 is electrically connected to the controller 13.

[0040] In this embodiment: the combined use of the movable door 11 and the double-layer flexible sealing ring 12 not only seals the box 1 to prevent outside air from flowing into the box 1 and maintains the vacuum environment inside the box 1, ensuring product quality, but also allows the movable door 11 to be opened to maintain the equipment inside the box 1, ensuring the normal use of the device and improving its stability. Then, the combined use of the controller 13 and the air pressure detector 14 not only allows for real-time detection of the air pressure inside the box 1, but also allows for adjustment of the air pressure inside the box 1 through the vacuum machine 7 and the electric exhaust valve 8 according to the actual situation. Furthermore, it allows for precise control of the sizing component 2 according to the actual situation, realizing the sizing operation of the carbon fiber cloth and improving the sizing effect of the carbon fiber cloth.

[0041] Working Principle: During the carbon fiber cloth sizing operation, firstly, by pulling the handle 308, the moving rod 307 is moved smoothly, simultaneously moving the connecting plate 302 smoothly and compressing the spring 303, releasing the restrictive effect of the sealing component 3, allowing the carbon fiber cloth to smoothly enter the chamber 1. Simultaneously, under the action of the spring 303, the connecting plate 302 smoothly returns to its original position, thereby causing the rubber sealing block 306 and rubber roller 305 to return to their original positions and contact the carbon fiber cloth. This restricts the movement of the carbon fiber cloth while blocking outside air, thus maintaining a vacuum environment inside the chamber 1, creating favorable conditions for subsequent sizing operations. After the carbon fiber cloth enters the chamber 1, the controller 13, in conjunction with the air pressure detector 14, can detect the air pressure inside the chamber 1 in real time. The pressure is adjusted according to the actual situation by using vacuum machine 7 and electric exhaust valve 8 to create a suitable sizing environment inside the chamber 1. The operation of sizing component 2 can also be precisely controlled according to the actual situation. Then, under the action of cylinder 206, the connecting bracket 207 can be moved smoothly, and the pressing roller 208 can be moved smoothly at the same time, thereby immersing the carbon fiber cloth into the interior of the liquid storage tank 201, so that the carbon fiber cloth can fully contact the sizing liquid, and thus the sizing liquid can fully penetrate into the interior of the carbon fiber cloth. At the same time, by using the cooperation of limiting roller 204 and coating roller 205, the carbon fiber cloth can pass smoothly through the two, which not only restricts the movement of the carbon fiber cloth, but also coats the surface of the cloth with sizing liquid, preventing uneven sizing and ensuring product quality.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
