Install the metal-coated fiber cloth on the unwinding roller (10) to ensure that the cloth can be unrolled smoothly; S2, starting the second motor (31), driving the winding roller (2) to rotate, and preparing to start the winding of the prepreg; S3, extending the hydraulic rod (12) to push the impregnation roller (8) downward, pushing the metal-coated fiber cloth into the impregnation tank (27) so that the cloth is fully immersed in the resin; S4, the soaked prepreg passes between two scrapers (7), and the distance between the two scrapers (7) is adjusted by rotating the gears (16) at the rear ends of the two scrapers (7), so that the scrapers (7) scrape off the excess resin on the surface of the metal-coated fiber; S5, the treated metal-coated fiber prepreg enters a drying box (14) and is dried in the drying box (14); S6, starting the motor 1 (21), driving the mounting shaft (22) and the cam (23) to rotate, the cam (23) pushing the screening plate (26) to move inside the machine body (1), filtering the impurities inside the recovered resin, and at the same time, the brush plate (28) is pressed against the screening plate (26) under the action of the spring (29), flattening the resin accumulated on the top of the screening plate (26), and preventing the resin from clogging the screening plate (26); S7, start the water pump 2 (20), and send the filtered resin back to the impregnation tank (27) through the feed pipe (40), so as to realize the recycling of the resin; S8, start water pump 1 (4), so that water in the water storage tank (5) flows through the water delivery pipe (3) into the heat transfer pipe (38) in the drying box (14), absorbs the residual heat inside the drying box (14), and then returns to the inside of the water storage tank (5) through the connecting pipe (6), thereby realizing the recovery and utilization of the residual heat.
