[0002] Carbon fiber (CF) has excellent characteristics such as high specific strength, high specific modulus, and low temperature resistance. It is the most important reinforcing material for resin-based composites in recent years. In order to improve the interfacial bonding strength of composite materials, carbon fiber needs to be surface treated to improve adhesion and wettability with the matrix material.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention provides a processing system for carbon fiber modified coating, such as Figure 1-6As shown, it includes an immersion box 1 and an inert gas roasting box 25. The inner wall of the immersion box 1 is symmetrically provided with a movable groove, a lifting component is provided in the movable groove, a placement rack 2 is connected to the outside of the lifting component, and a clamping component for clamping the carbon fiber cloth is provided inside the placement rack 2. The two placement racks 2 are fixedly connected by a pair of connecting racks 3. Slide rods 4 are symmetrically fixedly installed on one side of the opposite side of the two connecting racks 3. Screw rods 5 are symmetrically rotatably installed on the other side of the opposite side of the two connecting racks 3. The external threaded sleeve of the upper screw rod 5 is provided with a square tube 6, and the other end of the square tube 6 is slidably sleeved on the upper slide rod 4. A round tube 7 is provided between the lower screw rod 5 and the slide rod 4, and the square tube 6 is set away from the round tube 7. , the bottom of the round tube 7 and the square tube 6 are both provided with a spray hole, and one end of the screw rod 5 is provided with a driving component that drives it to rotate. The interior of the immersion box 1 is provided with a glue injection component for injecting or extracting sol into the square tube 6 and the round tube 7. When in use, the carbon fiber cloth is clamped between a pair of placement racks 2 through a clamping component, and the placement rack 2 is driven by the lifting component to drive the carbon fiber cloth to descend into the immersion box 1. Sol is placed in the immersion box 1. When the placement rack 2 descends, it drives the connecting rack 3, the slide rod 4, the screw rod 5, the square tube 6 and the round tube 7 to descend. At the same time, the driving component drives the screw rod 5 to rotate and drive the square tube 6 and the round tube 7 to move, and cooperates with the glue injection component to inject sol into the round tube 7 so that the sol is ejected through the spray hole. At the same time, the glue injection component extracts the sol in the square tube 6, so that the sol in the immersion box 1 is drawn into the glue injection component through the nozzle and the square tube 6. At the same time, as the carbon fiber cloth descends, the sol pushes upward so that the sol can be pressed into the carbon fiber cloth. With the movement of the square tube 6 and the round tube 7, the glue injection component can simultaneously make the round tube 7 spray the sol to spray the sol onto the carbon fiber cloth, accelerating the sol to penetrate the carbon fiber cloth. At the same time, the sol is sucked into the square tube 6 to form a sol flow, which helps the sol to penetrate the carbon fiber cloth. Subsequently, the placement rack 2 can be driven to rise by the lifting component. At this time, the glue injection component extracts the sol into the glue injection component through the nozzle and the round tube 7 to form a flowing sol. The glue injection component Injecting the sol into the square tube 6 and spraying it toward the carbon fiber cloth can help the sol penetrate the carbon fiber cloth. Similarly, the driving assembly drives the screw 5 to rotate and drives the square tube 6 and the round tube 7 to reset. While the carbon fiber cloth rises, the sol pushes the carbon fiber cloth downward to help the sol penetrate. The movement of the carbon fiber cloth in the sol is coordinated with the injection and flow guidance of the sol by the square tube 6 and the round tube 7, so that the speed of the sol penetrating the carbon fiber cloth can be greatly improved. Subsequently, the carbon fiber cloth infiltrated with the sol is removed and placed in the inert gas baking box 25 for baking. The sol forms a coating attached to the carbon fiber cloth, thereby realizing the modification of the carbon fiber cloth, improving its performance, and realizing the processing of the modified coating of the carbon fiber cloth.

[0029] like Figure 2As shown, the glue injection assembly includes a cylinder body 8 fixedly mounted in the middle of the bottom wall of the immersion box 1, and a partition 10 is fixedly mounted inside the cylinder body 8. The partition 10 divides the interior of the cylinder body 8 into two cavities of the same size. A piston 9 is provided in the cavity. A pair of hoses 11 are provided on the top of the cylinder body 8, which are respectively connected to the two cavities. The top ends of the two hoses 11 are respectively connected to the square tube 6 and the round tube 7. The bottom of the connecting frame 3 is provided with an extrusion assembly for driving the piston 9 to move. The connecting frame 3 descends and squeezes the piston 9 under the round tube 7 through the extrusion assembly so that the sol in the cavity is squeezed outward, and the sol enters the round tube 7 through the hose 11. The viscera are sprayed out through the spray hole, and at the same time, the extrusion assembly on the other side drives the piston 9 under the square tube 6 to move, so that the piston 9 moves away from the partition 10, so that the sol in the immersion box 1 is drawn into the cavity through the spray hole, square tube 6, and hose 11. When the connecting frame 3 rises, the extrusion assembly can drive the initial position, and the piston 9 under the round tube 7 is reset, so that the sol is drawn into the cavity through the spray hole, round tube 7 and hose 11. When the extrusion assembly can drive the initial position, the piston 9 under the square tube 6 is reset, so that the sol in the cavity is squeezed outward, and the sol is sprayed out through the hose 11, square tube 6 and spray hole.

[0030] like Figure 2 As shown, the extrusion assembly includes a push rod 12 fixedly connected to the side of the piston 9 away from the partition 10, the bottom end of the connecting frame 3 is fixedly connected to the extrusion block 13 through a connecting rod, the extrusion block 13 cooperates with the push rod 12, and a first spring is provided on the side of the piston 9 close to the partition 10. The connecting frame 3 descends and drives the extrusion block 13 to move accordingly through the connecting rod, so that the extrusion push rod 12 drives the piston 9 below the round tube 7 to move in the direction close to the partition 10, and at the same time compresses the first spring to deform it to generate a force. At the same time, the extrusion block 13 on the other side gradually cancels the extrusion of the lower push rod 12. At this time, the compressed first spring releases the force to drive the piston 9 below the square tube 6 to move in the direction away from the partition 10, so that a pair of pistons 9 move in the same direction. When the connecting frame 3 rises, the pistons 9 on both sides can move in the same direction to reset the pistons 9. When the connecting frame 3 falls, the piston 9 under the round tube 7 moves to squeeze the sol in the cavity outward so that the sol is ejected through the hose 11, round tube 7, and spray hole. The piston 9 under the square tube 6 moves to draw the sol in the immersion box 1 into the cavity through the spray hole, square tube 6, and hose 11. When the connecting frame 3 rises, as the piston 9 is reset, in the initial position, the piston 9 under the round tube 7 cooperates with the spray hole, round tube 7, and hose 11 to draw the sol in the immersion box 1 into the cavity. At the same time, in the initial position, the piston 9 under the square tube 6 squeezes the sol in the cavity outward so that the sol is ejected through the hose 11, square tube 6, and spray hole.

[0031] like Figure 2As shown, the extrusion block 13 is provided with an arc surface on the side close to the push rod 12. The arc surface of the extrusion block 13 close to the round tube 7 faces downward, and the arc surface of the extrusion block 13 close to the square tube 6 faces upward, so that when the connecting frame 3 descends or rises, it can cooperate with the extrusion block 13 and the first spring to drive the two pistons 9 to move in the same direction.

[0032] like Figure 4 and Figure 6 As shown, the driving assembly includes a gear 14 fixedly connected to one end of the screw rod 5, a mounting groove is provided on the inner wall of the immersion box 1, and the inner wall of the mounting groove is provided with driving teeth 15 engaged with the gear 14. The connecting frame 3 descends to drive the screw rod 5 and the gear 14 to descend, and the gear 14 rolls along the driving teeth 15 to drive the screw rod 5 to rotate to drive it.

[0033] like Figure 4 As shown, the lifting assembly includes a motor 16 fixedly connected to the top of the immersion box 1, the bottom end of the output shaft of the motor 16 extends to the movable groove and is fixedly connected to a screw 17, the external threaded sleeve of the screw 17 is provided with a movable block 18, the movable block 18 matches the movable groove, and one side of the movable block 18 is fixedly connected to the placement rack 2. Starting the motor 16 causes its output shaft to rotate forward to drive the screw 17 to rotate, thereby driving the movable block 18 and the placement rack 2 to descend. Conversely, the motor 16 can be started to cause its output shaft to rotate in the reverse direction to realize the ascent of the placement rack 2.

[0034] like Figure 2 As shown, the clamping assembly includes a pull rod 19 slidably installed on the top of the placement frame 2, the bottom end of the pull rod 19 extends to the inside of the placement frame 2 and is fixedly installed with a splint 20, and the outer sleeve of the pull rod 19 is provided with a second spring, and the second spring is located between the placement frame 2 and the splint 20. Pulling the pull rod 19 drives the splint 20 to rise, thereby compressing the second spring to deform it and generate a force, and the two ends of the carbon fiber cloth are respectively placed under the two splints 20. Release the pull rod 19, and the second spring releases the force to drive the splint 20 to descend so that the two ends of the carbon fiber cloth are clamped and fixed.

[0035] like Figure 5As shown, the outer parts of the lower slide rod 4 and the lower screw rod 5 are both sleeved with a fixed block 21, the fixed block 21 on the slide rod 4 is slidably connected to the slide rod 4, the fixed block 21 on the screw rod 5 is threadedly connected to the screw rod 5, both ends of the round tube 7 are rotatably connected to the fixed block 21, both ends of the round tube 7 are sleeved with a torsion spring 22, the two ends of the torsion spring 22 are respectively fixedly connected to the fixed block 21 and the round tube 7, a carrier plate 24 is fixedly installed on the outside of the connecting frame 3, one side of the round tube 7 and the bottom of the carrier plate 24 are provided with transmission teeth 23, when the connecting frame 3 descends, the lower screw rod 5 rotates to drive the fixed block 21 and the round tube 7 to move along its surface, and the transmission teeth 23 are used to rotate the fixed block 21 and the round tube 7. The cooperation makes the circular tube 7 rotate forward, so that the downward-facing spray hole of the circular tube 7 rotates to face upward. When the transmission teeth 23 on the circular tube 7 are separated from the transmission teeth 23 on the carrier plate 24, the force of the torsion spring 22 can keep the circular tube 7 from deflecting in the subsequent movement, keeping the spray hole facing upward. When the connecting frame 3 rises, the circular tube 7 can be reset on the contrary. When the circular tube 7 is reset, the transmission teeth 23 above it engages with the transmission teeth 23 on the carrier plate 24, so that the circular tube 7 rotates and the spray hole rotates to face downward, so that the remaining sol in the circular tube 7 can be discharged, avoiding the sol solidification and clogging of the circular tube 7, and ensuring the normal use of subsequent processing.

[0036] Working principle: When in use, the carbon fiber cloth is clamped between a pair of placement racks 2 through the clamping assembly, and the motor 16 is started to rotate its output shaft in the forward direction to drive the screw 17 to rotate, thereby driving the movable block 18 and the placement rack 2 to descend, so that the carbon fiber cloth is driven to descend into the immersion box 1. Sol is placed in the immersion box 1. When the placement rack 2 descends, it drives the connecting rack 3, the slide rod 4, the screw rod 5, the square tube 6 and the round tube 7 to descend. The connection rack 3 descends and drives the screw rod 5 and the gear 14 to descend. The gear 14 rolls along the driving teeth 15 to drive the screw rod 5 to rotate in the forward direction, thereby driving the square tube 6, the fixed block 21 and the round tube 7 to move. The rotation of the lower screw rod 5 drives the fixed block 21 and the round tube 7 to move along its surface. Through the cooperation of the transmission teeth 23, the round tube 7 is moved forward. The piston 9 below the square tube 6 moves in the direction close to the partition 10, and the first spring is compressed to deform and generate a force, while the extrusion block 13 on the other side gradually cancels the extrusion of the lower push rod 12. At this time, the compressed first spring releases the force to drive the piston 9 below the square tube 6 to move in the direction away from the partition 10, so that a pair of pistons 9 move in the same direction. The movement of the plug 9 squeezes the sol in the cavity outward so that the sol is ejected through the hose 11, the round tube 7, and the spray hole. The ejected sol sprays the sol onto the carbon fiber cloth, accelerating the sol to penetrate the carbon fiber cloth. The piston 9 under the square tube 6 moves through the spray hole, the square tube 6, and the hose 11 to draw the sol in the immersion box 1 into the cavity. The sol is sucked into the square tube 6 to form a sol flow, which helps the sol to penetrate the carbon fiber cloth. At the same time, as the carbon fiber cloth descends, the sol pushes upward so that the sol can be pressed into the carbon fiber cloth. Conversely, the motor 16 can be started to rotate its output shaft in the opposite direction to realize the rising of the placement rack 2. Conversely, the screw rod 5 can be reversed, thereby driving the square tube 6, the fixed block 21, and the round tube 7 to move and reset them. When the connecting rack 3 rises, conversely, two The piston 9 on the side moves in the same direction to reset the piston 9. As the piston 9 is reset, when the initial position is reached, the piston 9 under the round tube 7 cooperates with the spray hole, round tube 7, and hose 11 to draw the sol in the immersion box 1 into the cavity, forming a flow of sol, which helps the sol to penetrate the carbon fiber cloth. At the same time, when the initial position is reached, the piston 9 under the square tube 6 squeezes the sol in the cavity outward, so that the sol is ejected through the hose 11, square tube 6, and spray hole, accelerating the sol to penetrate the carbon fiber cloth. At the same time, the carbon fiber cloth rises, and the sol pushes it downward. Similarly, the sol is pressed into the carbon fiber cloth. The movement of the carbon fiber cloth in the sol cooperates with the injection and flow guidance of the square tube 6 and round tube 7 to greatly improve the speed of the sol penetrating the carbon fiber cloth. As the round tube 7 is reset,When the circular tube 7 is reset, the transmission teeth 23 above it mesh with the transmission teeth 23 on the carrier plate 24, causing the circular tube 7 to rotate and the nozzle to rotate downward, allowing the remaining sol in the circular tube 7 to be discharged, preventing the sol from solidifying and clogging the circular tube 7 when not in use, ensuring normal use in subsequent processing. The carbon fiber cloth then leaves the sol in the soaking box 1. The carbon fiber cloth that has been infiltrated with the sol is then removed and placed in the inert gas baking box 25 for baking. The sol forms a coating on the carbon fiber cloth, achieving modification of the carbon fiber cloth, improving its performance, and completing the processing of the modified coating on the carbon fiber cloth.
