The invention discloses a system with an efficient sizing device for preparing a gypsum board. The system comprises the sizing device. The sizing device comprises a sizing unit and a glue conveying unit. The sizing unit comprises a sliding rod base, a glue feeding fixing ring, a glue feeding pipe base, a glue feeding pipe, a glue feeding plate, a guiding rod, a spring, fixing box iron, a sizing support, a butterfly bolt, a fixing screw, a scraper and a recycling glue groove. The scraper is located below the glue feeding pipe and connected with the glue feeding pipe base through the fixing screw. The recycling glue groove is formed below the scraper. The glue conveying unit comprises a ball valve controlling glue conveying, the aperture of the ball valve is set to the fixed threshold value, and the sizing amount is far larger than the usage amount of white emulsion. Due to the fact that the mode of combination of the efficient sizing device and excessive recycling is adopted in the system, the problem of insuf
