[0034] A carbon fiber release cylinder 7 is provided on the support frame 3. The carbon fiber release cylinder 7 can be optionally rotated. The carbon fiber release cylinder 7 is used to release the carbon fiber preservative 5. The released carbon fiber preservative 5 passes through a plurality of tensioning pulleys 6 and then enters the preservative tank 21. The preservative tank 21 is used to coat the carbon fiber preservative 5 inserted into the preservative tank 21 with polyaryletherketone resin.

[0035] The carbon fiber preservative 5 is a carbon fiber tape or a carbon fiber filament.

[0036] The carbon fiber preservative 5 coated in the preservative tank 21 can be attached to the reel 4 under the action of the aromatic ether ketone resin coated on the surface.

[0037] The reel 912 is fixed with a central axis 41 , and the reel 912 rotates around the central axis 41 , and is wound around the reel 4 when the reel 4 rotates, as shown in the direction of arrow Y in the figure.

[0038] The impregnation tank 21 is placed on a translation table 2, which can move relative to the structural frame 1. In the first state, that is, in use, the reel 4 rotates, and the translation table 2 moves in a direction away from the support frame 3, as shown in the arrow X direction. The reel 4 rotates, and the coated carbon fiber impregnation material 5 is wound around the reel 4.

[0039] In some optional embodiments, the dipping tank 21 contains polyaryletherketone resin, preferably ST-PEKKS-TM resin.

[0040] As a feasible implementation, the translation platform 2 has several bends 23 , which guide and restrict the translation platform 2 to the structural frame 1 .

[0041] As a feasible implementation method, the translation platform 2 is provided with rollers on a side close to the structural frame 1 .

[0042] In the first state, the roller rolls, and the translation platform 2 is guided and restricted by the bend 23 and moves away from or close to the support frame 3 .

[0043] Optionally, the bends 23 are further connected with a transverse section 231;

[0044] As a feasible embodiment, the impregnation tank 21 is provided with a plurality of guide columns 213. In the first state, the carbon fiber impregnation material 5 inserted into the impregnation tank 21 is wound around the reel 4 after being positioned and guided multiple times by the plurality of guide columns 213. The plurality of guide columns 213 control the carbon fiber impregnation material 5 to be immersed in the solvent or resin multiple times.

[0045] Preferably, the plurality of guide posts 213 have different heights, and the guide posts 213 are limited in number and height to control the coating time of the carbon fiber preservative 5 in the preservative tank 21 .

[0047] As a feasible implementation method, the impregnation tank 21 includes a solvent tank 211 and a resin tank 212. In the first state, the carbon fiber impregnation 5 extended into the impregnation tank 21 first enters the solvent tank 211 and then extends from the resin tank 212. The solvent tank 211 can hold a solvent to pre-treat the carbon fiber impregnation 5 according to production requirements.

[0048] As a feasible implementation, the reel 4 is a hollow metal cylinder, and a heating device is attached to the inner surface of the metal cylinder, preferably a quartz heating sticker, which is used to maintain the temperature of the reel 4 and adapt to low temperature environments.

[0049] As a feasible implementation method, the translation table 2 is driven by a screw device 91, and the screw device 91 includes a screw 911 and a sleeve 912 that matches the thread of the screw 911. The sleeve 912 is fixedly connected to the translation table 2, and the wheel transmission system 8 drives the screw 911. The screw 911 rotates, driving the translation table 2 to move.

Under the action of the screw device 91, the translation table 2 approaches or moves away from the support frame 3.

[0056] Preferably, the driving gear 82 and the driven gear 81 have different ratios.

[0057] The driving gear 82 and the driven gear 81 have different gear ratios, which are used to adjust the ratio of the rotation speed of the reel 4 and the moving speed of the translation table 2 to be constant, so as to prevent the difference in moving speed from causing the difference in product quality.

[0058] In some optional embodiments, the carbon fiber releasing cylinder 7 may be optionally connected to a recovery motor 71 , which drives the carbon fiber releasing cylinder 7 to rotate and recover the released carbon fiber preservative 5 .
