The second motor 56 drives the second positioning roller 57 to rotate, thereby driving the blade to continue to move, and the first positioning roller 55 moves up and down inside the positioning shell 51 through the positioning block 54, which is convenient for blades of different sizes. Subsequently, the blade enters between the upper and lower plastic scrapers 66, the plastic scrapers 66 on both sides are opened by the blade, the plastic scrapers 66 move towards the inside of the connecting shell 64, the positioning bolt 67 moves in the sliding groove 68, the third spring 610 is compressed, and the plastic scrapers 66 move to different degrees due to different positions of contact with the blade, which can be more suitable for blades of different degrees of distortion. Then, the second electric push rod 61 is connected to the external power supply and started, the output shaft of the second electric push rod 61 drives the upper and lower sliding cylinders 63 to slide on the surface of the second fixed rod 62, so that the plastic scrapers 66 move back and forth on the surface of the blade, achieving the scraping of the paint surface after softening the paint surface. When the blade opens the plastic scrapers 66, the two clamps 611 also rotate, the two clamps 611 tightly adhere to the sides of the blade, so that the plastic scrapers 66 move horizontally on the surface of the blade, reducing the possibility of the blade moving with the plastic scrapers 66, thereby preventing the paint surface from being scraped incompletely; S7: When the plastic scraper 66 scrapes the paint, the gas tank 71 is connected to the power supply and the valve is opened to fill the inside of the connecting gas pipe 72 with gas. The gas enters the inside of the second bellow 75 through the connecting gas pipe 72 and is discharged through the gas collecting head 76.
