Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-4 A continuous fiber high-strength prepreg impregnation device includes an impregnation part 1 and fiber filaments 2. The impregnation part 1 includes an impregnation box 11. The top surface of the impregnation box 11 is open, and the lower side and upper part of the interior of the impregnation box 11 are horizontally rotatably connected to multiple guide rollers 12, and multiple spacers 13 are fixed transversely through the outer circumference of the multiple guide rollers 12. Multiple fiber filaments 2 are provided, and the multiple fiber filaments 2 are separated by the spacers 13 and guided up and down by the guide rollers 12 to enter the interior of the impregnation box 11. The interior of the impregnation box 11 is filled with impregnation resin. A scraper 3 is provided on the top of the impregnation box 11, and the scraper 3 is used to scrape off the impregnation resin adhered to the multiple fiber filaments 2. During use, the resin slurry for impregnation is added into the impregnation box 11, and the multiple fiber filaments 2 are guided by the guide rollers 12 and transported into the impregnation box 11. In the process, multiple fiber filaments 2 adhere to the resin slurry in the impregnation box 11, and then the multiple fiber filaments 2 adhere to the resin slurry and are guided upward by the guide roller 12 to move upward. The multiple fiber filaments 2 that move upward pass through the scraper 3 to scrape off the excess resin slurry on the multiple fiber filaments 2, and then the multiple fiber filaments 2 are guided and transported into the impregnation box 11 through the guide roller 12. The multiple fiber filaments 2 adhere to the resin slurry in the impregnation box 11, and then the multiple fiber filaments 2 are guided upward by the guide roller 12. The multiple fiber filaments 2 are repeatedly transported vertically and repeatedly enter the impregnation box 11 for adhering to the resin slurry, so that the resin is impregnated multiple times during the fiber impregnation. The multiple guide rollers 12 are set up to repeatedly immerse the multiple fiber filaments 2 into the impregnation box 11 multiple times. The multiple resin impregnation of the fibers ensures that the fibers are fully impregnated, thereby improving the fiber impregnation effect.

[0027] See Figure 2 and Figure 3A wind box 14 is fixed on the bottom surface of the impregnation box 11, and an air intake pipe 15 is fixed on the bottom surface of the wind box 14. An air intake pump 16 is assembled on the air intake pipe 15 of the wind box 14, and a plurality of exhaust pipes 17 are evenly and vertically fixed on the top surface of the wind box 14. During use, the air intake pump 16 on the air intake pipe 15 on the wind box 14 is started, and the air intake pump 16 drives external air into the wind box 14. The air is discharged into the impregnation box 11 through the multiple exhaust pipes 17 on the wind box 14. The air flows upward in the impregnation box 11, stirring the resin slurry in the impregnation box 11, thereby improving the sufficient impregnation of the resin slurry.

[0028] See Figure 2 and Figure 4 The scraper 3 includes a scraper 33, which is horizontally arranged on the upper part of the immersion box 11, and a plurality of scraping holes 331 are vertically penetrated on the scraper 33 in the horizontal direction. The plurality of fiber filaments 2 pass through the plurality of scraping holes 331 on the scraper 33 one by one. Rod seats 32 are fixed on both end surfaces of the scraper 33, and a hole seat 31 is vertically penetrated and inserted on the rod seat 32, and the bottom end of the hole seat 31 is fixed on the outer wall of the immersion box 11. A spring 34 is vertically arranged between the rod seat 32 and the hole seat 31, and the spring 34 is fixed on the outer wall of the immersion box 11. The two ends of 4 are respectively fixed on the adjacent end faces of the rod seat 32 and the hole seat 31. During use, the multiple fiber filaments 2 that move upward pass through the multiple scraping holes 331 on the scraper 33, and the excess resin slurry on the multiple fiber filaments 2 is scraped off by the scraper 33. At the same time, in order to ensure the effectiveness of the scraping by the scraper 33, the rod seats 32 at both ends of the scraper 33 slide vertically on the hole seat 31, pulling the spring 34 to deform, so that the deformation force of the spring 34 ensures the downward movement of the scraper 33, thereby ensuring the effectiveness of the multiple fiber filaments 2 in scraping off the excess resin slurry.

[0029] During use, the resin slurry for impregnation is added into the impregnation box 11, and the multiple fiber filaments 2 are guided by the guide rollers 12 to be transported into the impregnation box 11. The multiple fiber filaments 2 adhere to the resin slurry in the impregnation box 11, and then the multiple fiber filaments 2 adhere to the resin slurry, and then are guided upward by the guide rollers 12 to move upward, and the multiple fiber filaments 2 that move upward pass through the scraper 3 to scrape off the excess resin slurry on the multiple fiber filaments 2, and then the multiple fiber filaments 2 are guided by the guide rollers 12 to be transported into the impregnation box 11, and the multiple fiber filaments 2 adhere to the resin slurry in the impregnation box 11, and then the multiple fiber filaments 2 are guided upward by the guide rollers 12, and the multiple fiber filaments 2 are repeatedly transported vertically and repeatedly enter the impregnation box 11 for adhering the resin slurry, so that the resin impregnation is performed multiple times during the fiber impregnation, and the multiple guide rollers 12 are provided for repeatedly impregnating the multiple fiber filaments 2 into the impregnation box 11 multiple times.
