This utility model discloses a quantitative liquid filling machine for producing electroplated aluminum adhesive, relating to the field of filling machine technology. It includes a tank, which further includes a quantitative mechanism. A sealing cap is threaded onto the top of the tank. The invention utilizes an electric telescopic rod, which moves a push plate to push the liquid flowing into the conveying pipe towards a one-way valve. Due to the one-way valve's inability to allow outflow, the liquid in the conveying pipe flows through the one-way valve into the discharge pipe, achieving quantitative filling. When the push plate moves the adhesive in the conveying pipe towards the discharge pipe, the one-way valve precisely opens, ensuring all material enters the discharge pipe.
