[0032] When working, the wind power blade is put into one end of the fixing frame 1, and is transported to the inside of the spraying box 11 through the conveying table 10. When the blade enters the inside of the spraying box 11, the movement is stopped. The paint in the middle of the paint box 12 is discharged from the connecting pipe 13 through the control system, enters the inside of the flexible hose 14, and is discharged to the spray head 15, so that the paint is sprayed on the surface of the blade. The spray head 15 is controlled to move on the top of the spraying box 11, so that the paint is uniformly attached to the surface of the blade. When one side of the blade is sprayed, the fan 16 is powered on and opened after the heating wire 111 is powered on, so that the fan 16 enters the air discharge pipe 17, and then enters the middle of the drying box 18 through the air discharge groove 19. At this time, the air current absorbs heat through the heating wire 111, forms a hot current, and is sprayed downward. The baffle 112 blocks the hot current from flowing to both sides, and the guide plate 113 guides the hot current to the middle. During the process that the blade moves out of the spraying box 11 through the conveying table 10, the hot current is blown to the surface of the blade after spraying, so that the hot current is uniformly sprayed to the surface of the blade, the paint surface of the blade is quickly dried, the adsorption plate 24 is installed in the inside of the adsorption box 23, the fan 21 is powered on and opened during the process that the blade is sprayed, the fan 21 rotates, the air current in the inside of the spraying box 11 during the spraying process is sucked in through the fan 21, and then is discharged to the inside of the adsorption box 23 through the air outlet cylinder 22.

When the blade enters the inside of the spraying box 11, the brush 31 is in contact with the surface of the blade. Since the blade is irregular, when the brush 31 contacts the convex surface of the blade, the brush 31 is elastically contracted through the two springs 3. When the brush 31 not subjected to extrusion is elastically reset through the two springs 3, the surface of the blade is always in contact with the surface during the movement. The surface of the blade is cleaned during the movement. During the spraying process, the paint is sprayed to the surface of the conveying table 10. During the process that the conveying table 10 rotates, the paint on the surface of the conveying table 10 is scraped off through the end of the scraper 41. The installation block 51 on one side of the collection box 52 is inserted into the middle of the installation plate 5. At this time, the collection box 52 is fixed to the bottom of the scraper 41. During the process that the paint on the surface of the conveying table 10 is scraped off through the scraper 41, the paint is scraped off and enters the inside of the collection box 52. The paint cleaned through the collection box 52 is collected. During the spraying process of the blade, the spraying condition of the blade is directly observed through the visual plate 6.
