Technical Field

[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. Carbon fiber is lighter than metal aluminum, but stronger than steel. It has the characteristics of high hardness, high strength, light weight, high chemical resistance, and high temperature resistance. However, carbon fiber is prone to oil on the surface during processing and needs to be removed, otherwise it will affect the subsequent processing of the carbon fiber. Therefore, a surface degreasing device for carbon fiber production is needed.

By setting an automatic unloading component 3, the degreased carbon fiber can be wiped and automatically moved out of the cleaning box 1, thereby achieving the effect of automatic unloading, preventing workers from getting dust on the surface of the carbon fiber when taking the carbon fiber, and greatly improving the practicability of the device.

[0027] See also Figure 1 to Figure 7 A surface degreasing device for carbon fiber production includes a cleaning box 1. The front and rear sides of the cleaning box 1 are both provided with square through holes 2. The square through holes 2 can be used to conveniently insert the carbon fiber into the cleaning box 1 for cleaning and degreasing, and can also conveniently automatically remove the degreased carbon fiber from the cleaning box 1 for unloading.

[0028] An automatic unloading assembly 3 is arranged inside the cleaning box 1, and the automatic unloading assembly 3 includes a first support plate 301 and a second support plate 307. A side surface of the first support plate 301 close to the inner wall of the cleaning box 1 and a side surface of the second support plate 307 close to the cleaning box 1 are fixedly connected to the inner wall of the cleaning box 1.

[0029] The first support plate 301 and the second support plate 307 can both support the first squeezing roller 303, the second squeezing roller 304, the third squeezing roller 305 and the fourth squeezing roller 306, so as to facilitate the removal of the carbon fiber from the inside of the cleaning box 1 and achieve the effect of automatic unloading. Two wiping plates 302 are fixedly connected to the upper surface of the first support plate 301. The side surfaces of the two wiping plates 302 close to each other are provided with absorbent cloths, which can wipe off the moisture on the surface of the carbon fiber passing through here.

[0030] The top ends of the two wiping plates 302 are fixedly connected to the bottom surface of the second support plate 307, the upper surface of the first support plate 301 is rotatably connected to the first squeezing roller 303 and the second squeezing roller 304, the top ends of the first squeezing roller 303 and the second squeezing roller 304 are rotatably connected to the upper surface of the second support plate 307, the outer surface of the first squeezing roller 303 is fixedly connected to the first gear 308, the outer surface of the second squeezing roller 304 is fixedly connected to the second gear 309, and the first gear 308 and the second gear 309 are meshed with each other.

[0031] By utilizing the meshing between the first gear 308 and the second gear 309, the second squeezing roller 304 can be driven to rotate when the first squeezing roller 303 rotates, and the second squeezing roller 304 and the first squeezing roller 303 can rotate relative to each other, so that the carbon fiber can be squeezed to move, which is convenient for subsequent wiping of the carbon fiber.

[0032] The upper surface of the first support plate 301 is rotatably connected to the third extrusion roller 305 and the fourth extrusion roller 306. The top ends of the third extrusion roller 305 and the fourth extrusion roller 306 are both rotatably connected to the upper surface of the second support plate 307.

The third gear 310 and the fourth gear 311 are meshed with each other.

[0033] By utilizing the meshing between the third gear 310 and the fourth gear 311, the third squeezing roller 305 can be driven to rotate when the fourth squeezing roller 306 rotates, and the fourth squeezing roller 306 and the third squeezing roller 305 can be made to rotate relative to each other, so that the cleaned carbon fiber can be squeezed to move it and limited, so that the carbon fiber plate can be easily removed from the inside of the cleaning box 1, thereby achieving the effect of automatic unloading of the carbon fiber after degreasing.

[0034] The automatic unloading assembly 3 also includes a first motor 312, which is fixedly mounted on the inner wall of the cleaning box 1. The first motor 312 is fixed to the inner wall of the cleaning box 1 by bolts to facilitate subsequent disassembly and maintenance.

[0035] The output shaft of the first motor 312 is fixedly connected to the first pulley 313, the outer surface of the first extrusion roller 303 is fixedly connected to the second pulley 314, the first pulley 313 and the second pulley 314 are connected by belt transmission, the outer surface of the second extrusion roller 304 is fixedly connected to the third pulley 315, the outer surface of the fourth extrusion roller 306 is fixedly connected to the fourth pulley 316, and the third pulley 315 and the fourth pulley 316 are connected by belt transmission.

[0036] By utilizing the transmission connection between the first pulley 313 and the second pulley 314, the first pulley 313 can drive the second pulley 314 and the first squeezing roller 303 to rotate when rotating, thereby driving the second squeezing roller 304 to rotate. By utilizing the transmission connection between the third pulley 315 and the fourth pulley 316, the fourth squeezing roller 306 and the third squeezing roller 305 can be driven to rotate, so that the first squeezing roller 303 and the second squeezing roller 304 can rotate relative to each other, and the third squeezing roller 305 and the fourth squeezing roller 306 can also rotate relative to each other, so that the carbon fiber can be removed from the inside of the cleaning box 1, thereby achieving the effect of automatic unloading.

[0037] The bottom surface of the cleaning box 1 is fixedly connected with a connecting plate 6, and the bottom surface of the connecting plate 6 is provided with a cleaning component 4, which includes a water tank 401 and two water distribution tanks 404. The upper surface of the water tank 401 is fixedly connected with the bottom surface of the connecting plate 6. The connecting plate 6 can support the water tank 401 to prevent the water tank 401 from falling due to being too heavy.

[0038] Water pumps 402 are fixedly installed on the left and right sides of the water tank 401. The output ends of the two water pumps 402 are fixedly connected to water pipes 403. The ends of the two water pipes 403 away from the water pumps 402 are fixedly connected to two water diversion tanks 404 respectively. The water inside the water tank 401 can be pumped out to the inside of the water diversion tank 404 through the water pumps 402, which is convenient for the subsequent cleaning of the carbon fiber.

[0039] The sides of the two water diversion tanks 404 that are away from each other are fixedly connected to the inner wall of the cleaning box 1, and the sides of the two water diversion tanks 404 that are close to each other are provided with a group of nozzles 405. The two groups of nozzles 405 can be used to clean both sides of the carbon fiber, which is convenient and quick, and greatly improves the work efficiency. An activated carbon filter plate 406 is placed on the upper surface of the water tank 401. The activated carbon filter plate 406 can absorb oil stains in the water, thereby realizing the recycling of water and avoiding the waste of water resources.

[0040] A fixed component 5 is provided inside the cleaning box 1, and the fixed component 5 includes a second motor 501 and a guide rail 509. The second motor 501 is fixedly installed on the inner wall of the cleaning box 1, and the output end of the second motor 501 is fixedly connected to a threaded rod 502. One end of the threaded rod 502 away from the second motor 501 is rotatably connected to the inner wall of the cleaning box 1, and the outer surface of the threaded rod 502 is threadedly connected to a moving block 503.

[0041] By driving the threaded rod 502 to rotate through the second motor 501, the moving block 503 can be moved, thereby driving the carbon fiber to move, which is convenient for the subsequent double-sided cleaning of the carbon fiber. The inner wall of the moving block 503 is slidably connected to the limiting rod 504, and the left and right ends of the limiting rod 504 are fixedly connected to the inner wall of the cleaning box 1. The setting of the limiting rod 504 can limit the moving block 503 to prevent the moving block 503 from rotating with the threaded rod 502 when the outer surface of the threaded rod 502 moves.

[0042] The bottom surface of the moving block 503 is fixedly connected to an electric telescopic rod 505 , the telescopic end of the electric telescopic rod 505 is fixedly connected to a moving plate 506 , the bottom surface of the moving plate 506 is fixedly connected to two first limit plates 507 , and a first sponge 508 is arranged between the two first limit plates 507 .

[0043] The first sponge 508 can wrap the upper surface of the carbon fiber to prevent the carbon fiber from colliding with internal parts and causing damage. The electric telescopic rod 505 can drive the movable plate 506 and the first limiting plate 507 to move downward, which is convenient for limiting and fixing the carbon fiber and facilitating the cleaning of the carbon fiber.

[0044] The left and right ends of the guide rail 509 are fixedly connected to the inner wall of the cleaning box 1, and the inner wall of the guide rail 509 is slidably connected with a slider 510. The inner walls of the guide rail 509 and the slider 510 should be set to be relatively smooth so that the slider 510 can slide on the inner wall of the guide rail 509, so that the carbon fiber can drive the slider 510 to move in the same direction when moving.

[0045] Two second limiting plates 511 are fixedly connected to the upper surface of the slider 510, and the second limiting plates 511 can limit the carbon fiber plate. A second sponge 512 is arranged between the two second limiting plates 511. A group of first through holes 513 are opened on the bottom surface of the guide rail 509, and the water splashed into the guide rail 509 can be discharged through the set first through holes 513.

[0046] The inner bottom wall of the cleaning box 1 is provided with a second through hole 7, and the second through hole 7 can discharge the water after cleaning inside the cleaning box 1 out of the cleaning box 1 to the inside of the water tank 401, so as to facilitate the subsequent recycling of the water.

[0047] Working principle: when it is necessary to degrease the surface of the carbon fiber, insert the carbon fiber into the interior of the cleaning box 1 through the square through hole 2. After entering the cleaning box 1, the carbon fiber will be limited by the second limiting plate 511 to stand upright on the upper surface of the second sponge 512. Then start the electric telescopic rod 505 to drive the movable plate 506 to descend. When the movable plate 506 descends, it will drive the first limiting plate 507 and the first sponge 508 to descend, so that the first sponge 508 squeezes the upper surface of the carbon fiber. At the same time, the first limiting plate 507 limits the carbon fiber, thereby achieving the effect of fixing the carbon fiber. By starting the second motor 501 to drive the threaded rod 502 to rotate, the moving block 503 moves on the outer surface of the threaded rod 502, and the carbon fiber can be driven to move. When the carbon fiber moves, it will drive the slider 510 to slide on the inner wall of the guide rail 509. The water pump 402 is started to pump the water in the water tank 401 into the water diversion chamber 404. The water entering the water diversion chamber 404 will be sprayed out from the nozzle 405 to clean the surface of the carbon fiber, thereby achieving the effect of double-sided cleaning of the carbon fiber. When the carbon fiber moves to contact the second squeezing roller 304 and the second squeezing roller 304, the second motor 501 is turned off and the electric telescopic rod 505 is started to shrink, so that the fixation of the carbon fiber can be released. At the same time, starting the first motor 312 will drive the first squeezing roller 303, the second squeezing roller 304, the third squeezing roller 305 and the fourth squeezing roller 306 to rotate, so that the carbon fiber can be moved to the left. When the carbon fiber moves to contact the wiping plate 302, the wiping plate 302 will wipe the moisture on the surface of the carbon fiber, so that the carbon fiber is moved out from the square through hole 2 opened on the back of the cleaning box 1, thereby achieving the effect of automatically unloading the carbon fiber after cleaning, which is convenient and quick, and greatly improves work efficiency.
