The application of PLC in electrostatic powder sprayer

In order to prevent the glass from scratching and mildewing in storage and transportation, the anti-mildew powder should be added between the glass. For the demand of the powder spraying, the electrostatic powder sprayer control system based on PLC was developed. Spraying constant powder for the middle - part glass of variable thickness realized by controlling two frequency converters respectively. By electrostatic technology improved the homogeneity of powder and the adsorption force. The touch screen used to set parameters and to display temperature, statistical production data and alarm. The result shows that this system is credible and stable and the parameters tested are accordant with the requirements.
