This machine adopts PLC microcomputer programmable control, integrating light, electrical mechanical, sensing and pneumatic execution. The piston stroke is driven by a servo motor with precise stroke positioning and fast and slow filling. When the filling is close to the bottle mouth, the speed pressure is reduced to prevent the liquid from splashing and overflowing due to the large force. The machine has high degree of automation and convenient adjustment. When changing specifications or correcting measurement, it only needs to be adjusted on the display screen to meet the requirements. It can be applied to vegetable oil, honey, jam, syrup, preparation, oil and daily chemical industry.
