Baking paint spraying equipment is required to paint and bake the surface of objects. During the spraying process, in order to avoid the generation of static electricity and sparks, which may cause fires or explosions, anti-static treatment is required.

[0003] However, for existing baking paint spraying equipment, the anti-static method usually directly connects the equipment or workpiece to the ground through a grounding wire. This physical connection method may limit the mobility and flexibility of the equipment. For baking paint spraying operations that require frequent movement or position adjustment, it is not flexible and convenient enough. Moreover, this method requires ensuring good connection and conductivity of the grounding wire, otherwise it may affect the anti-static effect, and its practicability is weak.

[0004] To solve this technical problem, the utility model proposes an anti-static baking paint spraying device. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an anti-static baking paint spraying device, which can effectively solve the problems mentioned in the background art.

Specifically, during spraying, when the static eliminator fan is started, the high-voltage power generator and the servo motor will be started simultaneously. When the servo motor is started, the fan blades can be driven to rotate through the rotating shaft pipe to generate blowing. When the high-voltage power generator is started, it will discharge through the ion ring to ionize the surrounding air into a large number of positive and negative ions.

Through the operation handle, paint can be pumped into the material conveying pipe 1 through the material conveying hose, and then sprayed out through the spraying pipe 101 and the spraying head 102 to carry out spraying.

[0026] An electrostatic eliminator fan 2 is provided at the outer end of the material conveying pipe 1. The electrostatic eliminator fan 2 can eliminate the static electricity generated during the spraying process. A baffle 18 is connected to the outer end of the material conveying pipe 1. The electrostatic eliminator fan 2 can be connected to the baffle 18. The baffle 18 is used to prevent the electrostatic eliminator fan 2 from moving excessively. A threaded groove is provided at the outer end of the material conveying pipe 1. A moving ring 19 is threadedly connected to the outer end of the threaded groove. The moving ring 19 can be connected to the electrostatic eliminator fan 2. The electrostatic eliminator fan 2 is located between the moving ring 19 and the baffle 18. Anti-slip grooves are provided at the outer end of the moving ring 19. The anti-slip grooves can facilitate the rotation of the moving ring 19. When the moving ring 19 rotates and acts on the threaded groove, it will be able to move, and thus cooperate with the baffle 18 to clamp and fix the electrostatic eliminator fan 2.

[0027] The electrostatic eliminator fan 2 includes a circular ring shell 3. A connecting rod 7 is connected inside the circular ring shell 3. An ion ring 9 is clamped inside the connecting rod 7. A protective box 10 is connected to the lower end of the circular ring shell 3. A high-voltage power generator 11 is connected inside the protective box 10. The ion ring 9 is connected to the high-voltage power generator 11 through a wire. When the high-voltage power generator 11 is started, it will discharge through the ion ring 9 and can ionize the surrounding air into a large number of positive and negative ions (prior art).

[0028] A support frame 4 is connected inside the circular ring shell 3. A rotating shaft tube 5 is rotatably connected inside the support frame 4. A fan blade 6 is connected to the outer end of the rotating shaft tube 5. The fan blade 6 is located between the support frame 4 and the connecting rod 7.

The rotating rod 17 is rotatably connected inside the circular ring shell 3. Thus, when the servo motor 12 is started, it will drive the transmission gear 15 to rotate through the steering gears 16 and the rotating rod 17. When the transmission gear 15 rotates and acts on the toothed ring 14, it will be able to make the rotating shaft tube 5 rotate inside the support frame 4, thereby driving the fan blade 6 to rotate. Thus, blowing will be generated. This wind can blow a large number of positive and negative ions in the air onto the object surface to neutralize static electricity, thereby effectively preventing the generation of static electricity during the spraying process.

[0029] Protective mesh covers 13 are provided on both sides of the circular ring shell 3. Circular holes are provided at the centers of the protective mesh covers 13.
