Spray coating system with constant pressure and stirring function

摘要

The present invention discloses a spray coating system with constant pressure and stirring function. The spray coating system comprises a stirring barrel containing a mixture material, a stirrer stirring the mixture material, a control valve used for controlling a spray rate of the packaging material, a nozzle connected to the control valve for spouting the packaging material in spray form, a circulation pipe line connected between the stirring barrel and the control valve and a peristaltic pump mounted at the circulation pipe line. Thereby, the spray coating system is applied to the dispensing process of the LED to stir the packaging material and spout the packaging material in spray form, and can transmit the packaging material remained back to the stirring barrel by the peristaltic pump for avoiding the extraneous entering to the packaging material and blocking the nozzle to advance the spray coating quality and efficiency.

主权项

1. A spray coating system with constant pressure and stirring function, comprising:
a stirring barrel, containing a mixture material; a stirrer, connected to the stirring barrel, stirring the mixture material in the stirring barrel; a control valve, having a cavity body used to contain the mixture material; a nozzle, connected to the cavity body, mixing the mixture material and a gas pressed and spouting the mixture material mixed in spray form; a peristaltic pump, pumping the mixture material remained in the cavity body back to the stirring barrel after spouting; and a circulation pipe line, connected between the stirring barrel, the cavity body of the control valve and the peristaltic pump, wherein the peristaltic pump is mounted between an output location of the control valve and the stirring barrel.
