Technical Field

[0001] This utility model relates to the field of silicon carbide film coating technology, and in particular to a continuous silicon carbide film carbon fiber plate coating mechanism. Background Technology

[0002] In aerospace, new energy and other fields, it is often necessary to coat the surface of continuous carbon fiber sheets with silicon carbide film to improve their high temperature resistance, wear resistance and other properties. Therefore, a special coating mechanism is required to complete this operation.

[0003] However, in the existing technology, most coating mechanisms have problems such as uneven coating and poor film flatness, and it is difficult to achieve continuous production. At the same time, it is inconvenient to adjust the conveying angle of the board during the coating process, and excess coating material is easily wasted. The drying and subsequent conveying after coating are also not smooth enough, which affects the overall production efficiency and coating quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of uneven coating, weak continuous production capacity, inconvenient angle adjustment, material waste and poor drying and conveying in the existing technology, and to propose a continuous carbon fiber plate coating mechanism for silicon carbide film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a silicon carbide film continuous carbon fiber plate coating mechanism, comprising a substrate and a support plate, wherein the support plate is rotatably mounted on the top of the substrate, a positioning frame is fixedly mounted on the top of the support plate, a conveying pipe is fixedly mounted inside the positioning frame, and nozzles are fixedly mounted at equal intervals on the conveying pipe, and a brushing mechanism is provided between two adjacent positioning frames, wherein the brushing mechanism is fixedly connected to the support plate.

[0006] The brushing mechanism includes a support frame, a slide table, a movable block, and a pressure roller. The slide table is slidably connected to the support frame, and the movable block is connected to the slide table by a spring. The pressure roller is rotatably mounted on the bottom of the movable block. The support frame is fixedly mounted on the top of the support plate. A servo motor is fixedly mounted on one end of the support frame, and a lead screw is fixedly connected to the output end of the servo motor.

[0010] Preferably, a dryer is fixedly installed at the end of the substrate, and the dryer is located at the end of the support plate.

[0011] Preferably, a guide plate is fixedly connected to one side of the dryer, and the guide plate is inclined.

[0012] Preferably, the bearing plate has a groove inside, which is located below the positioning frame and the brushing mechanism.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the nozzle on the conveying pipe can spray silicon carbide film material onto the continuous carbon fiber plate. The brushing mechanism between adjacent positioning frames processes the sprayed material. The slide table is connected to the movable block by a spring.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a continuous carbon fiber plate coating mechanism for silicon carbide film, including a substrate 1 and a support plate 2. The support plate 2 is rotatably mounted on the top of the substrate 1. A positioning frame 5 is fixedly mounted on the top of the support plate 2. A conveying pipe 4 is fixedly mounted inside the positioning frame 5. Spray nozzles are fixedly mounted on the conveying pipe 4 at equal intervals. A brushing mechanism 6 is provided between two adjacent positioning frames 5. The brushing mechanism 6 is fixedly connected to the support plate 2. The brushing mechanism 6 includes a support frame 61, a slide table 63, a movable block 66, and a pressure roller 67. The slide table 63 is slidably connected to the support frame 61. The movable block 66 is connected to the slide table 63 by a spring. The pressure roller 67 is rotatably installed at the bottom of the movable block 66. The support frame 61 is fixedly installed on the top of the bearing plate 2. A servo motor 62 is fixedly installed at one end of the support frame 61. A lead screw 64 is fixedly connected to the output end of the servo motor 62. The lead screw 64 is threadedly connected to the top of the slide table 63. A strip hole 65 is provided at the junction of the support frame 61 and the slide table 63. The strip hole 65 is set along the length direction of the support frame 61.

[0024] The specific setup and function of this embodiment are described below. The substrate 1 serves as the basic support. The support plate 2 is rotatably mounted on top of the substrate 1, allowing for angle adjustment. The positioning frame 5 is fixed to the top of the support plate 2 to fix the conveying pipe 4. The nozzle on the conveying pipe 4 can spray silicon carbide film material onto the continuous carbon fiber plate. The brushing mechanism 6 between adjacent positioning frames 5 processes the sprayed material. The support frame 61 is fixed to the support plate 2 to provide support. The servo motor 62 drives the lead screw 64 to rotate, causing the slide 63, threadedly connected to the lead screw 64, to slide along the slot 65 of the support frame 61. The slide 63 is connected to the movable block 66 via a spring. The bottom of the movable block 66 is pressed... Roller 67, under the action of spring, adheres tightly to the carbon fiber plate and spreads the silicon carbide film material evenly as it moves with slide table 63. The carbon fiber plate can be moved quickly by gravity through the rotation of the support plate 2. The positioning frame 5 ensures the stability of the conveying pipe 4 and the nozzle position, ensuring uniform spraying. In the spreading mechanism 6, servo motor 62 drives slide table 63 to move stably. The strip hole 65 restricts the movement trajectory of slide table 63. The spring keeps the pressure roller 67 in contact with the carbon fiber plate and prevents excessive pressure, which can avoid damaging the plate while ensuring the flatness of the film layer. All components work together to achieve stable and uniform coating of silicon carbide film on continuous carbon fiber plate, improve coating quality and efficiency, and meet the needs of continuous production.

[0025] Example 2: Figure 1 and Figure 2 As shown, a positioning stage 9 is fixedly installed on the upper surface of the substrate 1. One end of the support plate 2 is rotatably connected to the top of the positioning stage 9. An electric cylinder 8 is rotatably connected to the lower surface of the other end of the support plate 2. The electric cylinder 8 is rotatably installed on the upper surface of the substrate 1. A dryer 7 is fixedly installed at the end of the substrate 1. The dryer 7 is located at the end of the support plate 2. A guide plate 10 is fixedly connected to one side of the dryer 7. The guide plate 10 is inclined. A groove 3 is opened inside the support plate 2. The groove 3 is located below the positioning frame 5 and the brushing mechanism 6.

[0026] The overall effect of this embodiment is as follows: the positioning platform 9 on the upper surface of the substrate 1 is rotatably connected to one end of the support plate 2, and the electric cylinder 8, which is rotatably connected to the lower surface of the other end of the support plate 2, is mounted on the substrate 1. The extension and retraction of the electric cylinder 8 can drive the support plate 2 to rotate around the positioning platform 9 to adjust the tilt angle. The dryer 7 at the end of the substrate 1 is located at the end of the support plate 2 and is used to dry the coated carbon fiber board. The inclined guide plate 10 on one side of the dryer 7 can guide the conveying of the dried board. The groove 3 inside the support plate 2, located below the positioning frame 5 and the brushing mechanism 6, can accommodate excess coating material. The positioning platform 9 provides a stable rotation fulcrum for the support plate 2. The electric cylinder 8 realizes flexible adjustment of the angle of the support plate 2 and speeds up the conveying speed of the board. The dryer 7 can dry the coated board in time to avoid the film layer flowing and affecting the quality. The inclined guide plate 10 ensures that the board is conveyed smoothly after drying and prevents jamming. The groove 3 can collect excess material to reduce waste and at the same time assist in the positioning of the board to prevent deviation. The cooperation of each component improves the continuity and controllability of the coating process and further improves production efficiency and coating quality.

[0027] The device's operation and working principle are as follows: The substrate 1 serves as the base support. A continuous carbon fiber sheet is placed on the support plate 2. One end of the support plate 2 is rotatably connected to the positioning stage 9 on the substrate 1. An electric cylinder 8 connected to the lower surface of the other end extends and retracts, causing the support plate 2 to rotate around the positioning stage 9 to adjust the tilt angle, facilitating sheet material transport. The conveying pipe 4, fixed to the positioning frame 5 at the top of the support plate 2, sprays silicon carbide film material onto the carbon fiber sheet through its nozzle. During spraying, the groove 3 inside the support plate 2, located below the positioning frame 5 and the brushing mechanism 6, can accommodate excess coating material and assist in sheet positioning. After spraying, adjacent positioning frames 5... The brushing mechanism 6 starts working, and the servo motor 62 on the support frame 61 drives the lead screw 64 to rotate, so that the slide table 63, which is threadedly connected to the lead screw 64, slides along the strip hole 65 of the support frame 61. The slide table 63 is connected to the pressure roller 67 at the bottom of the movable block 66 by a spring. Under the action of the spring, the roller 67 is pressed against the carbon fiber plate. As the slide table 63 moves, it brushes the silicon carbide film material evenly. The brushed carbon fiber plate continues to be transported to the dryer 7 at the end of the substrate 1 for drying. The dried plate is guided to the next process by the guide plate 10 that is inclined on one side of the dryer 7, thus completing the entire coating process of the silicon carbide film continuous carbon fiber plate.
