An automatic feeding system for a coating machine

Abstract

The utility model relates to a kind of coating machine automatic feed system, including first storage unit, second storage unit, at least one third storage unit, at least one mixing unit and at least one buffer unit.Its advantage is in, the coating machine automatic feed system is realized efficient, accurate, stable material supply by modular design and intelligent control.The system uses whole-process automation control, utilizes pneumatic diaphragm valve and gear pump collaborative work, realizes the accurate on-demand delivery of silicone oil, solvent and various additives, and through multistage flowmeter real-time monitoring proportioning accuracy (error rate is lower than industry standard), combined with the viscosity meter closed-loop control mixed silicone oil viscosity (fluctuation range ±5%), ensure coating quality consistency.Double buffering design (mixing unit+buffer tank) and solvent double-path supply mechanism guarantee production continuity, even if coating machine can still continuously feed when mixing unit maintenance, make downtime waiting time reduce 90%.
