[0004] Furthermore, the interior of the shaped atomizing cover is provided with a shaped flow shroud.

[0005] Furthermore, the forming atomizing hood and the forming rectifier are sealed and installed on the motor base by threaded connection and sealed fit. Compressed air enters the sealed space of the forming atomizing hood and the forming rectifier through the atomizing air passage connecting pipe, and then air is injected through a ring of radiation holes on the outside of the forming atomizing hood, so that the powder can be controlled to form its shape after being discharged and further assists in making the powder fine and evenly distributed.

[0006] Furthermore, the air-suspended dustproof motor is mounted on the motor base.

[0007] Furthermore, the inner wall of the nozzle is provided with a dustproof brush to prevent powder from entering the air suspension dustproof motor.

[0009] Furthermore, the built-in electrostatic high-voltage module is for electrostatic emission. It is charged by an external controller, connected to the air-suspended dustproof motor, and transmitted to the nozzle to charge the powder, allowing the powder to be better adsorbed onto the workpiece surface.

[0010] The above technical solution has the following beneficial effects: This invention uses compressed air to drive the rotor to rotate at high speed. Combined with the atomizing air path and the forming rectifier, it achieves fine and uniform powder distribution and shape control, improving spraying efficiency and coating quality.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] See Figures 1 to 4The illustrated air-suspension dustproof powder rotary cup spray gun includes a spray gun housing 014, a nozzle 05, a forming atomizing hood 04, and a spray gun base 07. The spray gun housing 014 contains an air suspension air path connecting pipe 09, a rotational speed air path connecting pipe 10, a built-in electrostatic high-voltage module 012, a powder channel 013, an atomizing air path connecting pipe 011, and an inner powder tube 08. The spray gun housing 014 is positioned above the spray gun base 07. The top of the spray gun housing 014 is fitted with the forming atomizing hood 04. A nozzle 05 is located at the front end of the forming atomizing hood 04. The nozzle 05 is connected to the inner powder tube 08. The air suspension air path connecting pipe 09 is connected to an air suspension dustproof motor 02. Compressed air is supplied to the air suspension dustproof motor 02 through the air suspension air path connecting pipe 09. The air suspension dustproof motor 02 is also connected to the rotational speed air path connecting pipe 10. The inner powder tube 08 communicates with the powder channel 013.

[0014] Figure 1 In this design, the forming atomizing cover 04 has a forming rectifier 03 inside. The forming atomizing cover 04 and the forming rectifier 03 are sealed and installed on the motor base 01 by threaded connection and are sealed together. Compressed air enters the sealed space between the forming atomizing cover 04 and the forming rectifier 03 through the atomizing air passage connecting pipe 011, and then air is injected through a ring of radiation holes on the outside of the forming atomizing cover 04, so that the powder can be controlled to form its shape after being discharged, and further assists in making the powder fine and evenly distributed. The air-suspended dustproof motor 02 is mounted on the motor base 01. The inner wall of the nozzle 05 is equipped with a spray cup dustproof brush 06, preventing powder from entering the air-suspended dustproof motor 02. The spray gun base 07 is connected and fixed to the air suspension air path connecting pipe 09, the speed air path connecting pipe 10, the atomizing air path connecting pipe 011, the built-in electrostatic high voltage module 012, and the powder channel 013. The built-in electrostatic high voltage module 012 emits electrostatic charge and is charged by an external controller. It is then connected to the air-suspended dustproof motor 02 and transmitted to the nozzle 05, making the powder charged and allowing it to be better adsorbed onto the workpiece surface.

[0015] In practical use, compressed air is supplied to the air-suspended dustproof motor 02 through the air suspension air passage connection pipe 09, so that the rotor inside the air-suspended dustproof motor 02 is kept in a suspended state by air. After the rotor of the air-suspended dustproof motor 02 is suspended, the compressed air is made to rotate the rotor at high speed through the rotation speed air passage connection pipe 10. The powder enters the powder channel 013 and then enters the powder tube 08 inside the spray gun and then the nozzle 05. The rotor drives the nozzle 05 to rotate at high speed. After the powder passes through the high speed of the nozzle 05, it is made to be uniform and fine and evenly distributed. The forming atomizing cover 04 and the forming rectifier cover 03 are sealed and installed on the motor base 01 through the threaded connection and sealed. Compressed air enters the sealed space of the forming atomizing cover 04 and the forming rectifier cover 03 through the atomizing air passage connection pipe 011, and then sprays air through the outer ring of radiation holes of the forming atomizing cover 04, so that the powder can be controlled after it is discharged and further assists in making the powder fine and evenly distributed.
