[0020] Please see Figure 1-3 A powder coating device for processing polymer photovoltaic frames includes a powder coating chamber 1, a hook 2 at the top of the interior of the powder coating chamber 1, a door 3 on the front face of the powder coating chamber 1, an air duct 4 at the bottom of the interior of the powder coating chamber 1, a fan 5 mounted on the air duct 4, an automatic lifting device 6 on the left side of the powder coating chamber 1, an electrostatic powder coating gun 7 mounted on the automatic lifting device 6, a powder supply tank 8 on the left side of the automatic lifting device 6, and a high-voltage electrostatic generator 9 above the powder supply tank 8. The powder supply tank 8 and the electrostatic powder coating... The guns 7 are connected by a powder supply pipe 10. The end of the air duct 4 passes through the right side wall of the powder spraying chamber 1 and is connected to the air inlet 15 of the cyclone separator 11. A dust collection box 13 is provided on the right side of the cyclone separator 11. An inlet 20 is opened on the lower left side of the dust collection box 13, and an outlet 19 is opened on the upper right side of the dust collection box 13. The air outlet 16 of the cyclone separator 11 is connected to the inlet 20 of the dust collection box 13 through a conveying pipe 12. The bottom of the cyclone separator 11 is connected to the powder supply tank 8 through a return pipe 14.

[0021] The electrostatic powder spraying gun 7 and the high-voltage electrostatic generator 9 are electrically connected via a connecting wire.

[0022] The dust collector 13 is equipped with an air filter 17 inside, and an activated carbon filter layer 18 is provided inside the dust collector 13 and directly above the air filter 17.

[0023] A guide opening is provided on the left side wall of the powder spraying chamber 1, and the electrostatic powder spraying gun 7 is located in the guide opening.

[0026] The working principle and usage process of this utility model are as follows: First, the polymer photovoltaic frame is suspended on the hook 2 and grounded. Then, the electrostatic powder spraying gun 7, through the high-voltage electrostatic generator 9, causes the powder particles passing through the gun head to carry a negative charge. When the charged powder is sprayed onto the polymer photovoltaic frame workpiece, the workpiece itself, as a grounded body, carries a positive charge. The mutual attraction between these charges causes the powder to be evenly adsorbed on the workpiece surface, forming a complete coating. During the powder spraying process, the unattached powder coating is separated by starting the fan 5 and entering the cyclone separator 11 through the air duct 4. The separated powder coating is returned to the powder supply tank 8 through the bottom return pipe 14, saving resources. The separated gas is transported from the outlet 16 of the cyclone separator 11 through the conveying pipe 12 to the dust collection box 13. After being purified and dusted by the air filter 17 and activated carbon filter layer 18 in the dust collection box 13, it is discharged from the outlet 19. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
