This automatic peanut oil quantitative filling machine is viscous liquid quantitative filling machine designed for lubricant oil, cooking oil, salad oil, chemical liquid, motor oil, cream and grease. The machine is mainly composed of magnetic cylinders, cylinders and electrical control components. The utility model has the advantages of simple overall structure, small occupied area and easy operation. The quantification cup structure is adopted, and the cylinder piston is repeatedly moved by the cylinder to quantitatively fill the oil into the bottle, the quantitative accuracy is high, the filling speed is fast, and the double-speed filling is fast and slow, and the quantification is more accurate.
