[0026] Working principle and advantages of the present invention: When the carbon filament resin impregnation device for aircraft beams is used, the working process is as follows: like Figures 1 to 5As shown, the carbon filament is passed through the threading tube 23, then passes around the upper end of the wire wheel 24 and then passes around roller 2 46 and roller 1 45 in sequence, and roller 2 46 and wire wheel 1 24 are located on the same side of the carbon filament, and roller 1 45 is located on the other side of the carbon filament, and then the carbon filament passes through the middle of the two clamping plates 58 inside the two rotating drums 55 and then passes around roller 4 48, roller 3 47 and wire wheel 4 40 in sequence, and roller 1 45, roller 4 48 and wire wheel 4 40 are located on the same side of the carbon filament, and roller 3 47 is located on the other side of the carbon filament, and then the carbon filament passes through the center holes of each cone ring 61 inside the scraper 31 from bottom to top, then passes around the upper end of the wire wheel 3 27, passes through the threading tube 26, and then passes around the upper part of the wire wheel 2 25 and is wound on the winding reel 14.

[0027] As described above, after the carbon filament is threaded and wound, resin is injected into the impregnation box 2 and the resin liquid level is lower than the lower end of the scraper 31, and the motor 3 is started, so that the motor 3 drives the shaft 5 to rotate through the bevel gear set 4, so that the shaft 5 drives the tube shaft 13 and the winding reel 14 to rotate through the polygonal rod 12, and then the winding reel 14 winds up the carbon filament impregnated with resin in the impregnation box 2, and while the shaft 5 rotates, the crankshaft 9 is driven to rotate through the worm 8 and the worm wheel 7, so that the crankshaft 9 drives the tube shaft 13 and the winding reel 14 to move back and forth through the slide 10 and the push-pull rod 11, so that the wire is arranged while the carbon filament is wound, so that the winding of the carbon filament is more compact and smooth, and automatic winding is achieved after the carbon filament is impregnated with resin, saving time and effort.

[0028] As described above, the rotation of the crankshaft 9 drives the reciprocating screw 35 to rotate synchronously, so that the reciprocating screw 35 drives the slider 36 to move up and down, so that the angle between the two adjacent connecting rods in the multi-parallelogram structure increases and decreases reciprocatingly, so that the positions of roller 1 45, roller 2 46 and roller 3 47 are constantly changing. On the one hand, this increases the stroke of the carbon filament in the resin, which is convenient for increasing the wetting time. On the other hand, it can make the carbon filament constantly change its bending direction angle in the resin, so that the resin is immersed in the carbon filament more thoroughly. At the same time, the angle between the connecting rod 1 41 and the connecting rod 2 42 changes, and the rack 51 is driven to reciprocate through the connecting rod 5 49, so that the rack 51 drives the gear 2 52 and the gear 3 53 to rotate reciprocatingly, and then the gear 3 53 is driven to rotate reciprocatingly. The two gear rings 2 56 drive the two rotating drums 55 to perform synchronous rotational motion in opposite directions, so that the two pairs of clamps 58 rub the carbon filaments in opposite directions, so that the carbon filaments can be better impregnated with resin and the impregnation effect can be improved. Moreover, under the action of the spring 1 38, the wire wheel 4 40 adjusts the tension of the carbon filaments accordingly. When the impregnated carbon filaments pass through the cone rings 61 inside the scraper drum 31, the excess resin is scraped off, and the carbon filaments drive the wire wheel 3 27 to rotate when running, so that the wire wheel 3 27 drives the shaft rod 2 30 to rotate through the bevel gear set 2 29, and then the shaft rod 2 30 drives the scraper drum 31 to rotate through the gear 1 33 and the gear ring 1 32, so that the scraper drum 31 uses centrifugal force to discharge the resin scraped off the cone ring 61 through the through hole 62, so as to avoid the scraped resin from gathering and adhering to the carbon filament again.

[0029] As mentioned above, the rotation of shaft 15 drives impeller 16 to rotate at the same time, so that impeller 16 extracts the resin inside the impregnation box 2 through conduit 17, and through the push of impeller 16, enters the filter box 19 through conduit 2 18, and after being filtered and purified by filter screen 20, enters the impregnation box 2 again through conduit 3 22. This increases the fluidity of the resin, so that the resin and the surface of the carbon filament are better combined, and the filter screen 20 can filter out small particles of dirt and bubbles carried into the resin by the surface of the carbon filament, thereby ensuring the impregnation effect of the carbon filament.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
