Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a high-efficiency coating mechanism for prepreg of carbon fiber materials. Background Technology

[0002] A coating apparatus for carbon fiber prepreg is a device used to uniformly coat the surface of carbon fiber materials with resin-based coatings. This apparatus is primarily used in the prepreg process of carbon fiber, its function being to evenly coat the surface of the carbon fiber with resin to enhance the adhesion between the carbon fiber and the resin, thereby improving the performance of the carbon fiber material, especially enhancing its strength and durability during the subsequent curing process.

[0003] This coating mechanism typically consists of multiple functional modules to achieve precise coating of carbon fiber materials. First is the unwinding module, responsible for smoothly unfolding the rolled carbon fiber material and conveying it to subsequent processes. Next is the coating module, the core area, where the coating is evenly applied to the carbon fiber surface. After coating, the carbon fiber and coating are tightly bonded. Finally, the rewinding module neatly winds up the processed prepreg.

[0004] However, this traditional fixed guide shaft has significant shortcomings. In actual transportation, the tension of the carbon fiber is difficult to adjust in real time according to the actual situation. It cannot flexibly handle situations such as uneven carbon fiber material or fluctuations in transportation speed, leading to loosening or tearing of the carbon fiber during transport. This not only affects the normal transportation of carbon fiber but also reduces coating quality and production efficiency. Therefore, a high-efficiency coating mechanism for carbon fiber prepreg is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency coating mechanism for prepreg of carbon fiber materials, which aims to improve the problem that the guide shaft is relatively fixed in position, making it easy for carbon fiber to loosen or tear during transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency coating mechanism for prepreg of carbon fiber materials includes a fixed frame, a winding shaft, a first guide shaft, multiple second guide shafts and multiple coating shafts rotatably connected inside the fixed frame, multiple carbon fiber rolls rotatably connected to one side of the fixed frame, a holding box provided at the top of the coating shaft, a stirring assembly provided inside the holding box, and an adjustment assembly provided on the outer wall of the first guide shaft.

[0008] The adjustment assembly includes multiple sliders, which are rotatably connected to both ends of the guide shaft and slidably connected inside the fixed frame. Each slider has a connecting plate fixedly connected to one side, and each connecting plate has a fixed tube fixedly connected to both sides inside. Each fixed tube has a connecting post slidably connected inside, and each connecting post has a connecting shaft fixedly connected inside. Each connecting shaft has a connecting block rotatably connected to its outer wall. Each connecting post has a locking post fixedly connected to one end, which engages with the inside of the fixed frame. Each connecting post has a spring on its outer wall, with one end fixedly connected to the outer wall of the locking post and the other end fixedly connected to the inner wall of the fixed tube.

[0009] As a further description of the above technical solution:

[0010] The stirring assembly includes multiple stirring blades, which are located inside the container. The bottom of the inner wall of the container has multiple holes.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the container is fixedly connected to the inner wall of the fixing frame, and a motor is fixedly connected inside the fixing frame;

[0013] As a further description of the above technical solution:

[0014] The motor output end is fixedly connected to a connecting plate, and a connecting post two is fixedly connected to one side of the connecting plate. The connecting post two is rotatably connected to the inside of the holding box.

[0015] As a further description of the above technical solution:

[0016] A rotating cylinder is slidably connected to the outer wall of the connecting column 2, and the outer wall of the rotating cylinder is fixedly connected to one side of the stirring blade;

[0017] As a further description of the above technical solution:

[0018] Limiting posts are fixedly connected to both sides of the connecting plate, and the limiting posts are slidably connected inside the rotating drum. A connecting strip is fixedly connected to one end of the rotating drum.

[0019] As a further description of the above technical solution:

[0020] A second spring is provided on the outer wall of the second connecting column. One end of the second spring is fixedly connected to the outer wall of the rotating cylinder, and the other end of the second spring is fixedly connected to one side of the connecting disc.

[0021] As a further description of the above technical solution:

[0022] A fixing block is fixedly connected to the inner wall of the container, and a connecting ring is rotatably connected to the outer wall of the fixing block. The connecting ring and the connecting strip are in contact. A threaded column is rotatably connected inside the container, and the threaded column is in contact with the connecting ring.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by adjusting the up and down movement of the guide shaft and using the engagement between the locking post and the inside of the fixing frame, the position of the guide shaft is fixed, thereby achieving the effect of adjusting the surface tension of the carbon fiber. This solves the problem that the relatively fixed position of the guide shaft makes the carbon fiber prone to loosening or tearing during transportation, and enhances the transportation effect of the carbon fiber.

[0025] 2. In this utility model, the stirring blade is driven to rotate by a motor, and the connecting strip rotates on the outer wall of the connecting ring, so that the stirring blade performs reciprocating linear motion while rotating, thereby achieving the stirring effect on the epoxy resin inside the slot. This solves the problem that epoxy resin is prone to curing after long-term use and enhances the coating effect of epoxy resin. Attached Figure Description

[0033] 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.

[0034] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides: a high-efficiency coating mechanism for prepreg of carbon fiber materials, including a fixed frame 1, a winding shaft 2, a guide shaft 3, multiple guide shafts 4 and multiple coating shafts 5 rotatably connected inside the fixed frame 1, multiple carbon fiber rolls 6 rotatably connected to one side of the fixed frame 1, a holding box 15 is provided on the top of the coating shaft 5, a stirring assembly is provided inside the holding box 15, and an adjustment assembly is provided on the outer wall of the guide shaft 3;

[0035] The adjustment assembly includes multiple sliders 8, which are rotatably connected to both ends of a guide shaft 3. The guide shaft 3 provides stable axial support, allowing the sliders 8 to move along a suitable track. The sliders 8 are slidably connected inside a fixed frame 1, which fixes and supports them, ensuring stable sliding within the frame. Each slider 8 has a connecting plate 7 fixedly connected to one side. The connecting plate 7 connects and secures the various components, ensuring the structural stability of the entire adjustment assembly. Each connecting plate 7 has fixed tubes 12 fixedly connected to both sides inside. The fixed tubes 12 provide sliding guidance for the connecting post 11, ensuring smooth sliding within the tube. Each fixed tube 12 has a slidably connected connecting post 11, which bears and transmits torque during sliding, ensuring the stability and precise movement of other components. Each connecting post 11 is internally fixedly connected to a connecting shaft 10. The function of the connecting shaft 10 is to connect the connecting post 11 to other mechanical components and transmit rotational motion. Each connecting shaft 10 has a connecting block 9 rotatably connected to its outer wall. The connecting block 9, through rotation, links with other components, enabling the overall adjustment assembly to perform the required functions. Each connecting post 11 has a locking post 14 fixedly connected to one end. The locking post 14, by engaging with the inside of the fixing frame 1, keeps the connecting post 11 fixed in certain positions, ensuring the stability and reliability of the structure. The engagement between the locking post 14 and the inside of the fixing frame 1 provides precise positioning, preventing the connecting post 11 from shifting during movement. Each connecting post 11 has a spring 13 on its outer wall. The spring 13 provides a restoring force to the connecting post 11, ensuring it can smoothly return to its initial position during operation and preventing excessive friction or damage between components. One end of spring 13 is fixedly connected to the outer wall of the locking post 14, and the other end is fixedly connected to the inner wall of the fixing tube 12. The rebound force generated by spring 13 through this connection method can provide the necessary pressure between the locking post 14 and the fixing frame 1, thereby enhancing the stability of the connecting post 11 and ensuring the efficiency and accuracy of the adjustment component during use.

[0036] Specifically, in the process of adjusting the surface tension of carbon fiber, firstly, by rotating the connecting block 9 ninety degrees, the locking pin 14 at one end of the connecting post 11 is moved out of the fixed frame 1 via the connecting shaft 10. At this time, the movement of the locking pin 14 causes the spring 13 to compress, and the force of the spring 13 provides elastic support for subsequent adjustments. Next, the guide shaft 3 is pulled up and down, causing the slider 8 to slide inside the fixed frame 1, thereby effectively adjusting the surface tension of the carbon fiber. When the guide shaft 3 moves to the appropriate height, the connecting block 9 is rotated ninety degrees again, causing the connecting block 9 to reset. At this time, the reset action of the connecting block 9 pushes the locking pin 14 back into the fixed frame 1. The rebound force of the spring 13 further enhances the locking effect between the locking pin 14 and the inside of the fixed frame 1. In this way, the locking pin 14 is firmly positioned inside the fixed frame 1, ensuring the stable fixation of the guide shaft 3, improving the transport efficiency of the carbon fiber, and ensuring that it maintains a constant tension during production.

[0037] Reference Figure 2 and Figure 5The mixing assembly includes multiple mixing blades 21 located inside the container 15. Multiple holes are formed at the bottom of the inner wall of the container 15 to ensure effective contact and mixing of the mixing blades 21 with the material inside the container 15, thereby improving mixing efficiency. The outer wall of the container 15 is fixedly connected to the inner wall of the fixing frame 1. The fixing frame 1 provides stable support for the entire mixing assembly, ensuring that each component remains in a fixed position during operation and avoiding any unnecessary displacement. A motor 16 is fixedly connected inside the fixing frame 1, serving as the power source for the mixing assembly and driving its operation. A connecting plate 25 is fixedly connected to the output end of the motor 16, transmitting the power of the motor 16 to the connecting column 17. The connecting column 17 is rotatably connected inside the container 15, allowing rotation to propagate within the container 15. A rotating drum 20 is slidably connected to the outer wall of connecting column 27. The outer wall of rotating drum 20 is fixedly connected to one side of stirring blade 21. Through the fixed connection between rotating drum 20 and stirring blade 21, rotational motion can be directly transmitted to stirring blade 21, ensuring effective mixing of materials. Limiting columns 19 are fixedly connected to both sides of connecting plate 25. Limiting columns 19 are slidably connected inside rotating drum 20. The function of limiting columns 19 is to ensure that rotating drum 20 rotates within a certain range, avoiding excessive movement of rotating drum 20 and ensuring stability during the mixing process. A connecting strip 22 is fixedly connected to one end of rotating drum 20. Connecting strip 22 is used to further transmit the rotation of rotating drum 20, so that connecting ring 23 and rotating drum 20 maintain a tight fit. A spring 28 is provided on the outer wall of connecting column 27. One end of spring 28 is fixedly connected to the outer wall of rotating drum 20, and the other end is fixedly connected to one side of connecting plate 25. The function of spring 18 is to provide a certain restoring force to the rotating drum 20, ensuring its normal movement and stability during the stirring process, and preventing damage to components due to friction or excessive load. A fixing block 26 is fixedly connected to the inner wall of the container 15, and a connecting ring 23 is rotatably connected to the outer wall of the fixing block 26. The connecting ring 23 engages with the connecting strip 22, allowing the rotating drum 20 to operate smoothly through rotation and movement, thus enhancing the stirring effect. A threaded column 24 is rotatably connected inside the container 15, engaging with the connecting ring 23. The threaded column 24, through its threaded engagement with the connecting ring 23, achieves precise rotation control, enabling the stirring assembly to rotate within a certain range, thereby ensuring the uniformity and efficiency of the stirring process.

[0038] Specifically, in the process of applying epoxy resin to the carbon fiber surface, the epoxy resin is first poured into the container 15. The design of the container 15 ensures that the epoxy resin has sufficient space for storage and proper guidance. Using the holes at the bottom of the container 15, the epoxy resin is guided to the outer wall of the coating shaft 5, allowing it to be evenly applied to the carbon fiber surface. This operation provides an excellent bonding foundation for subsequent carbon fiber-to-carbon fiber contact, ensuring smooth processing. During the coating process, the threaded column 24 is rotated, pushing the connecting ring 23 to rotate. The rotation of the connecting ring 23 helps regulate the flow of epoxy resin, ensuring it evenly covers the outer wall of the coating shaft 5. Once the connecting ring 23 has rotated to the appropriate angle, the motor 16 is started. The motor 16, driven by the limiting columns 19 on both sides of the connecting column 17, further drives the stirring blades 21 on the outer wall of the rotating drum 20 to rotate. The stirring blade 21 thoroughly agitates the epoxy resin during rotation, ensuring good flowability before coating and preventing sedimentation or curing. Simultaneously, the rotating drum 20 drives the connecting strip 22 to rotate on the outer wall of the connecting ring 23. This motion further propels the drum 20 in a reciprocating linear motion. This reciprocating linear motion continuously agitates the epoxy resin inside the container 15, preventing curing during storage and ensuring ideal viscosity and flowability during use. Furthermore, the inclined surface of the connecting ring 23 propels the drum 20 in this reciprocating linear motion, while the second spring 18 provides a rebound force, ensuring the connecting strip 22 remains on the surface of the connecting ring 23. The force of the second spring 18 stabilizes the component operation, preventing loosening or friction between parts due to prolonged use, thus improving the stability and durability of the equipment. Through this series of precise mechanical operations, not only is the epoxy resin inside the container 15 fully stirred, but the curing of the epoxy resin is also effectively prevented, thus enhancing the uniformity and effect of the epoxy resin coating.

[0039] Working principle: During the process of applying epoxy resin to the carbon fiber surface, the epoxy resin is poured into the container 15. The epoxy resin is guided to the outer wall of the coating shaft 5 through the holes at the bottom of the container 15, ensuring even application of the epoxy resin to the carbon fiber surface and facilitating subsequent contact between carbon fibers. During this process, the threaded column 24 is rotated, pushing the connecting ring 23 to rotate. When the connecting ring 23 rotates to a suitable angle, the motor 16 is started, driving the stirring blades 21 on the outer wall of the rotating drum 20 through the limiting columns 19 on both sides of the connecting column 17. The rotating drum 20 stirs the epoxy resin. While rotating, the connecting strip 22 rotates on the outer wall of the connecting ring 23. The inclined surface of the connecting ring 23 pushes the rotating drum 20 to move back and forth in a linear motion, and pushes the second spring 18 to squeeze. The rebound force of the second spring 18 keeps the connecting strip 22 on the surface of the connecting ring 23 at all times. The reciprocating linear motion of the rotating drum 20 makes the epoxy resin inside the container 15 fully stirred, preventing the epoxy resin from curing and enhancing the coating effect of the epoxy resin.

[0040] During the adjustment of carbon fiber surface tension, the connecting block 9 is rotated 90 degrees, thereby driving the locking pin 14 at one end of the connecting pin 11 to move out of the fixed frame 1 through the connecting shaft 10, and causing the spring 13 to compress. Then, the guide shaft 3 is pulled up and down, causing the slider 8 to slide inside the fixed frame 1. When the guide shaft 3 moves to a suitable height, the connecting block 9 is rotated 90 degrees again, causing the connecting block 9 to reset, and pushing the locking pin 14 back into the fixed frame 1. The rebound force of the spring 13 is used to enhance the locking effect between the locking pin 14 and the inside of the fixed frame 1, thereby fixing the position of the guide shaft 3 and enhancing the transportation effect of carbon fiber.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
