Principle of roller coater bearing coating
Spray cup
Greasy gas scraped by roller coater
Bearing gas
Feed pipe (coating)
Turbine gas
Air motor
The principle of rotary atomization is to expand the coating pattern while micronizing the coating, which is suitable for electrostatic coating of coating manipulator.
Let the air motor rotate at high speed and create an air film between the shaft and the bearing by relying on the gas for turbine rotation. Use air (bearing gas) to make the mechanism rotate at high speed (the mechanism is non-contact). The coating will form fog particles under the action of this rotation, and move towards the coated object (workpiece) under the action of greasy gas pressure.
Principle of coating
High voltage generator
Spray gun (rotary atomization mode)
Coated object (workpiece)
Coating particles
Roller coater grounding
The grounding coating (workpiece) ends are used as positive electrodes, the coating spray device ends are used as negative electrodes, and the DC high voltage (70 K to 100 KV) is applied to make the coating particles carry negative electrodes, and fly along the power line to coat the positive coating (workpiece).
This Principle of roller coater bearing coating method of roller coater has many advantages, such as greatly reducing coating loss, coating man hours, reducing public hazards, improving working environment and so on.
