Insert both sides of the back plate 11 of the lifting shield 2 into the L-shaped guide rail 7 corresponding to the end of the spraying bin 1. First, adjust the height of the lifting shield 2 according to the size and height of the sprayed workpiece. When the height of the lifting shield 2 is determined, insert the positioning pins 14 into the corresponding pin holes 13 on both sides of the back plate 11, and support the positioning pins 14 above the L-shaped guide rail 7 to complete the positioning of the lifting shield 2.

The support rollers 5 rotate synchronously through the double-row sprocket 21 and the chain transmission, thereby driving the workpiece to move forward. The workpiece enters the spraying bin 1 from the corresponding feeding port 6 at one end, and is sprayed with plastic by the upper spray gun 8 and the lower spray gun 9. Then the material is discharged from the other end. Most of the plastic powder is recovered from the recovery port, and a part is extracted from the exhaust interface 19. Finally, the small particles of flying plastic powder move to both ends and are sucked into the lifting cover 2 through the through groove 15 of the back plate 11, and are extracted from the hose interface 12 at the top of the lifting cover 2. The utility model has a reasonable structure. L-shaped guide rails 7 are arranged at both ends of the plastic spraying bin 1 and on both sides of the material delivery port 6. The lifting shield 2 is slidably matched with the L-shaped guide rails 7 through the back plate 11, and a number of pin holes 13 are opened on both sides of the back plate 11. The pin holes 13 are matched with the positioning pins 14. The lifting shield 2 can be positioned by matching with the positioning pins 14 and supported on the top of the L-shaped guide rails 7. During the plastic spraying process, the plastic powder particles flying toward the two ends of the plastic spraying bin 1 are sucked into the lifting shield 2 through the through grooves 15 of the back plate 11, and are extracted from the hose interface 12 on the top of the lifting shield 2, which can prevent the flying plastic powder particles from entering the workshop from the material inlet and outlet positions of the plastic spraying bin 1, thereby protecting the production environment of the workshop. At the same time, since the height of the lifting shield 2 can be adjusted, it is suitable for workpieces of different heights, and the scope of application is greatly improved.
