Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production, in particular to a carbon fiber dipping device. Background Art

[0002] Carbon fiber dipping usually refers to the carbon fiber dipping process, which is a process of impregnating the carbon fiber surface with glue to form a glue layer, and then forming a gelatinous matrix through high temperature drying and thermal curing, and finally preparing carbon fiber composite materials under high temperature and high pressure conditions.

[0003] In the current existing technology, carbon fiber dipping is to put the carbon fiber into a dipping tank storing glue, wherein in order to continuously dipping, a plurality of support rods will be provided in the dipping tank, which are used to guide the carbon fiber to be immersed in the glue, wherein unwinding devices and winding devices will be installed on both sides of the dipping tank, relying on the above two devices to pull the carbon fiber continuously into the dipping tank to complete the dipping, and then pulled out from the dipping tank.

[0004] However, during use, in order to improve the efficiency of glue dipping, the staff will use a large amount of carbon fiber for glue dipping. However, the glue will not penetrate into the gaps between the carbon fibers, resulting in some areas not adhering to the glue, thus affecting the uniformity of the carbon fiber glue coating. Utility Model Content

[0005] To this end, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the glue fails to penetrate into the gaps between the carbon fibers, resulting in some areas not adhering to the glue, thereby affecting the uniformity of the glue coating on the carbon fibers.

[0006] In order to solve the above technical problems, the utility model provides a carbon fiber dipping device, including a dipping tank; a pair of support rollers are arranged inside the dipping tank; a support arm is arranged inside the dipping tank; the support roller is rotatably connected to the bottom of the support arm; a lifting frame is arranged in the dipping tank; a vibrating roller is arranged at the bottom of the lifting frame; a rotating shaft is rotatably connected to the dipping tank; a motor is fixedly connected to the side wall of the dipping tank; the output end of the motor is fixedly connected to the rotating shaft; the lifting frame is fixedly connected to the support shaft; a cam is fixedly connected to the rotating shaft at a position corresponding to the support shaft, and the vibrating roller is moved up and down by relying on the above arrangement. The upward movement of the vibrating roller will hit the carbon fiber, causing the tension of the carbon fiber to change and causing the carbon fiber to vibrate to a certain extent, so that it is convenient for glue to enter the gap between the carbon fibers, thereby improving the uniformity of glue coating on the surface of the carbon fiber, and reducing the situation where a large number of carbon fibers are dipped in glue and some areas of the carbon fibers are not dipped in glue.

[0007] In an embodiment of the present utility model, a pair of fixing seats are provided at the bottom of the support arm; a fixing roller is rotatably connected between the pair of fixing seats; a screw rod is threadedly connected to the fixing roller; the screw rod is rotatably connected to the support arm; the fixing roller is located at the bottom of the support roller, and by fixing the two ends of the carbon fiber, the situation of dislocation and mutual overlap is reduced.

[0008] In an embodiment of the present utility model, a guide rod is fixedly connected to the side of the fixing seat close to the support arm; a guide hole is opened at the corresponding position of the support arm for the guide rod; the guide rod penetrates through the guide hole and is slidably connected thereto. By the movement of the fixing seat, the guide rod is driven to slide in the guide hole of the support arm, so that the movement of the fixing seat can be guided and supported, thereby improving the stability of the fixing roller.

[0009] In an embodiment of the present utility model, a rod body is provided on the side of the support arm; the rod body is fixedly connected to the inner side wall of the impregnating tank; a plurality of springs are fixedly connected to the side of the rod body; the end of the spring is fixedly connected to the side of the support arm; the top end of the support arm is rotatably connected to the inner wall of the impregnating tank through a shaft.

[0011] In an embodiment of the present utility model, a guide seat is fixedly connected to the side wall of the impregnating tank; a chute is opened in the guide seat; the chute is slidably connected to the lifting frame.

[0012] In an embodiment of the present utility model, guide rollers are rotatably connected to the inner walls on both sides of the impregnating tank.

[0013] In an embodiment of the present utility model, the plurality of grooves are distributed in a linear array.

[0014] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0015] For the motor, rotating shaft, cam, support shaft, lifting frame and vibrating roller of the present utility model, during use, the carbon fiber passes through the bottom of the support roller, and the vibrating roller is located at the bottom of the carbon fiber. Then, the motor drives the rotating shaft and the cam to rotate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0025] Refer to Figures 1-5As shown in the figure, a carbon fiber impregnating device of the utility model includes an impregnating tank 11; a pair of support rollers 13 are arranged inside the impregnating tank 11; a support arm 12 is arranged inside the impregnating tank 11; the support rollers 13 are rotatably connected to the bottom of the support arm 12; a lifting frame 16 is arranged in the impregnating tank 11; a vibrating roller 18 is arranged at the bottom of the lifting frame 16; a rotating shaft is rotatably connected to the impregnating tank 11; a motor 14 is fixedly connected to the side wall of the impregnating tank 11; the output end of the motor 14 is fixedly connected to the rotating shaft; a support shaft 17 is fixedly connected to the lifting frame 16; a cam 15 is fixedly connected to the rotating shaft at a position corresponding to the support shaft 17; during use, the carbon fiber passes through the bottom of the support rollers 13, and the vibrating roller 18 is located at the bottom of the carbon fiber. Then, the motor 14 is relied on to drive the rotating shaft and the cam 15 to rotate. The rotation of the cam 15 will push the support shaft 17 to move upward, so as to drive the lifting frame 16 and the vibrating roller 18 to move upward. The upward movement of the vibrating roller 18 will strike the carbon fiber, causing its tension to change and the carbon fiber to vibrate to a certain extent. This can facilitate the entry of glue into the gaps between the carbon fibers, thereby improving the uniformity of the glue coating on the surface of the carbon fiber and reducing the situation that some areas of the carbon fiber are not coated with glue when a large amount of carbon fiber is impregnated.

[0026] Referring to Figures 1-5 As shown in the figure, a pair of fixed seats 21 are arranged at the bottom of the support arm 12; a fixed roller 22 is rotatably connected between the pair of fixed seats 21; a screw rod 23 is threadedly connected to the fixed roller 22; the screw rod 23 is rotatably connected to the support arm 12; the fixed roller 22 is located at the bottom of the support roller 13; during use, the staff can rotate the screw rod 23 to adjust the position of the fixed seat 21, thereby adjusting the distance between the fixed roller 22 and the support roller 13, so as to fix the carbon fiber. Due to vibration, the carbon fibers are prone to dislocation or overlap. By fixing the two ends of the carbon fiber, the situation of dislocation and overlap can be reduced.

[0027] Referring to Figure 4 As shown in the figure, a guide rod 31 is fixedly connected to one side of the fixed seat 21 close to the support arm 12; a guide hole 32 is opened at a position corresponding to the guide rod 31 on the support arm 12; the guide rod 31 passes through the guide hole 32 and is slidably connected thereto; during use, the movement of the fixed seat 21 will drive the guide rod 31 to slide in the guide hole 32 on the support arm 12. Therefore, it can play a role in guiding and supporting the movement of the fixed seat 21, thereby improving the stability of the fixed roller 22 and reducing the situation of shaking, and further improving the stability of fixation.

[0028] Referring to Figures 1-2As shown in FIGS. 3 and 4, a rod body 41 is provided on the side surface of the support arm 12; the rod body 41 is fixedly connected to the inner side wall of the dipping tank 11; a plurality of springs 42 are fixedly connected to the side surface of the rod body 41; the end of the spring 42 is fixedly connected to the side surface of the support arm 12; the top end of the support arm 12 is rotatably connected to the inner wall of the dipping tank 11 through a shaft; during use, when the force applied by the vibrating roller 18 to the carbon fiber is too large, the force applied by the carbon fiber to the support roller 13 overcomes the elastic force of the spring 42, and the elastic force of the spring 42 is directly related to the tension of the carbon fiber. Then, the support arm 12 will move and rotate, so as to control the tension of the carbon fiber between the two support rollers 13, thereby reducing the situation of carbon fiber breakage, and relying on the rotation of the support arm 12 to drive the carbon fiber to swing, so as to facilitate improving the full dipping of the carbon fiber with glue.

[0029] Referring to Figures 4-5 As shown, a plurality of grooves 5 are formed in both the fixed roller 22 and the support roller 13; the plurality of grooves 5 are arranged in a linear array; during use, the grooves 5 are used for the carbon fiber to pass through, and the carbon fiber is fixed by the plurality of grooves 5, so as to reduce the situation that the carbon fiber is stacked together after deviation, and improve the fixing effect on the carbon fiber.

[0030] Referring to Figure 2 As shown, a guide seat 61 is fixedly connected to the side wall of the dipping tank 11; a chute 62 is formed in the guide seat 61; the chute 62 is slidably connected to the lifting frame 16; during use, relying on the lifting frame 16 to slide in the chute 62 of the guide seat 61, the guide seat 61 guides and fixes the lifting frame 16, improves the stability during its movement, and reduces the situation of its deviation.

[0031] Referring to Figure 2 As shown, guide rollers 7 are rotatably connected to both inner side walls of the dipping tank 11. During use, the guide rollers 7 are provided for guiding and limiting, so that the carbon fiber is immersed in the glue and for guiding the carbon fiber.

[0032] Working principle: During use, the carbon fiber passes through the bottom of the support roller 13, and the vibration roller 18 is located at the bottom of the carbon fiber. Then, the motor 14 drives the rotating shaft and the cam 15 to rotate. The rotation of the cam 15 will push the support shaft 17 to move upward, thereby driving the lifting frame 16 and the vibration roller 18 to move upward. The upward movement of the vibration roller 18 will strike the carbon fiber, causing a change in its tension and making the carbon fiber vibrate to a certain extent. This can facilitate the entry of glue into the gaps between the carbon fibers, thereby improving the uniformity of the glue coating on the surface of the carbon fiber and reducing the situation where some areas of the carbon fiber are not coated with glue when a large number of carbon fibers are dipped in glue. During use, the operator can rotate the screw 23 to adjust the position of the fixed seat 21, thereby adjusting the distance between the fixed roller 22 and the support roller 13, so as to fix the carbon fiber. Due to vibration, the carbon fibers are prone to misalignment or overlap. By fixing the two ends of the carbon fiber, the occurrence of misalignment and overlap can be reduced. The movement of the fixed seat 21 will drive the guide rod 31 to slide in the guide hole 32 on the support arm 12. Therefore, the movement of the fixed seat 21 can be guided and supported, thereby improving the stability of the fixed roller 22 and reducing the occurrence of shaking, and further improving the stability of fixation. When the force applied by the vibration roller 18 to the carbon fiber is too large, the force applied by the carbon fiber to the support roller 13 overcomes the elastic force of the spring 42. The elastic force of this spring 42 is directly related to the tension of the carbon fiber. Then, the support arm 12 will move and rotate, thereby controlling the tension of the carbon fiber between the two support rollers 13, reducing the occurrence of carbon fiber breakage, and the rotation of the support arm 12 will drive the carbon fiber to swing, facilitating the full dipping of the carbon fiber with glue. The groove 5 is used for the carbon fiber to pass through, and multiple grooves 5 are used to fix the carbon fiber, reducing the situation where the carbon fibers are stacked together after deviation and improving the fixing effect of the carbon fiber. The lifting frame 16 slides in the chute 62 of the guide seat 61, and the guide seat 61 guides and fixes the lifting frame 16, improving its stability during movement and reducing the occurrence of deviation. The guide roller 7 is provided to guide and limit, enabling the carbon fiber to be immersed in the glue and guiding the carbon fiber.

[0033] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
