Electrostatic Rotor Powder Coating Machine

This powder coating machine specially designed for motor rotor slot to do insulating. It is of high automation and productivity.

Technical specification:

1. Rotor transferring speed: 0.1~1 m/min

2. Efficiency: as per above table     

3. Curing method: after heating and forming, put rotor into oven to further curing.

4. Powder thickness: 0.15~0.5 mm(it is depended on the powder feature).

Machine structure

A.   power coating unit:

1. Because of high pressure electrostatic stable and reliable feature, big power electrostatic high pressure generator device improves electrostatic absorption force, and powder coating rate is also improved.

2. Powder coating fluidization box and powder feeding fluidization box both can be disassembled quickly. It is convenient to completely clean the powder.

3. It is convenient to add powder, and it can be quickly done without over-flow.

4. Because of powder blowing device, the powder on rotor surface is removed cleanly, the fixture also is very clean, and it will not affect the powder on the rotor surface.

5. With a operation panel, it is easy to operate. The emergency stop button is interlock with machine. If emergency occurs, machine can be stopped immediately(except for the high frequency water pump, lamp filament and low voltage)

6. With a centralized electric control, it is convenient to maintain and repair.

7. This rotor powder coating machine adopts frequency speed regulator, which is constant speed, stable, stepless speed regulating. The actual speed and output are subject to the powder quantity cured by high frequency heater.

8. Equipped with auto power feeding device, this machine can add powder automatically without stopping machine. The powder adding volume keeps certain level. Therefore, powder on rotor surface is uniform and power thickness is same.

9. Above the working plate, there is a transparent protection cover (it is made by aluminium material, with a nice appearance and firm structure). There is a door at the key position, convenient for operation. The rotor air cooling device is installed at the backside of the machine monitor and integrated with machine monitor. There is an air suction cover at the top side.

10. The fixtures can be timely conveyed from the unloading area to the loading area by the special fixture transferring device. This can avoid operator commute between loading and unloading area, which improves the production efficiency and cuts down the labor cost.

11. The whole set machine has a nice appearance and reasonable structure. The metal door frame are all powder coated.

B.   Powder heating unit 

1. This rotor powder coating machine adapts high frequency (electronic valve) induction heater, which can heat the rotor quickly and melt the powder, especially the powder stick to the rotor surface.

2. High frequency cooler adapts advanced frozen type water cooler, with small dimension but good cooling performance.

 

C. powder recycling unit

Powder recycling unit adapts one set new model pulse three level powder recycling device. First level is cyclone separating tower. With an auto powder coating area, it can deliver most of the recycled powder back to the powder coating area.The second level is pulse counter blowing device to blow the powder off the filter, so operator no need to clean the powder. Recycling air volume is big enough to effectively avoid powder over-flow, which is helpful for environment protection.
