Spray nozzle for spray painting apparatus

Abstract

The present invention relates to a nozzle for a paint spraying device. More particularly, the nozzle relates to a nozzle for a paint spraying device. The nozzle atomizes a coating material supplied from the outside in a rotary dispersing unit for one time, and simultaneously the nozzle atomizes the coating material which is atomized in the rotary dispersing unit for one time for twice. The coatingmaterial can be micronized, the particle size of the finely divided coating particles can be ensured, thereby the coating quality is improved and the cleaning efficiency of the rotary dispersion unitis greatly improved.

Description

Technical field [0001] The invention relates to a nozzle for a paint spraying device. Specifically, it relates to a nozzle for a paint spraying device. The device atomizes paint supplied from the outside through a rotary dispersing unit once, and then atomizes the paint once atomized twice through the rotary atomizing unit. The paint can be atomized, and the particle size of the atomized paint can become more uniform, which can improve the coating quality and greatly improve the cleaning efficiency of the rotating dispersion unit. Background technique [0002] Generally, in the production line of automobiles, after the car body is completed, in order to prevent corrosion of the car body, enhance the sound insulation effect and visual beauty, and increase the value of the product, a painting process is required. [0003] On the coating line using the coating process, a coating film is formed on the car body through the following processes: After the car body passes through the dryi...

Problems solved by technology

[0008] However, the conventional nozzle 100 for a paint spraying device requires micronization of the paint particles in order to ensure the quality of the paint. Not only the atomization time is very short, but also the atomization efficiency is low, and the particle size of the paint cannot be guaranteed to be uniform when the paint is sprayed, and there are limitations in the micronization of the paint

[0009] In addition, the nozzle 100 for the conventional paint spraying device causes paint contamination when the particles of the paint collide with the inside of the serration portion 121.

Therefore, as mentioned earlier, it is not possible to ensure uniform particle size of the paint, which reduces the cleaning efficiency of the rotary dispersion unit when paint contamination occurs.
