The quantitative beverage filling machine has the beneficial effects that liquid compensation operation is automatically finished, and precise filling is realized; the filling precision is high; the quantitative beverage filling machine is simple in structure, and has environment-friendly and energy-saving effects.

Description

technical field [0001] The invention belongs to the technical field of filling machines, in particular to a beverage quantitative filling machine. Background technique [0002] Liquid filling machines can be divided into normal pressure filling machines, pressure filling machines and vacuum filling machines according to the filling principle. Atmospheric pressure filling machines are commonly used for canned beverages, and the normal pressure filling machines are filled under atmospheric pressure by the weight of the liquid. This type of filling machine is only suitable for filling low-viscosity and gas-free liquids such as milk and wine. [0003] To control the filling volume of the existing more advanced liquid filling machines, one is to install the liquid level detection device on the top of the material box, so as to detect the position change of the liquid level of the liquid raw material in the material box, when the liquid level After reaching the set liquid level,...

Problems solved by technology

[0003] To control the filling volume of the existing more advanced liquid filling machines, one is to install the liquid level detection device on the top of the material box, so as to detect the position change of the liquid level of the liquid raw material in the material box, when the liquid level After reaching the set liquid level, the filling switch is controlled in real time. Due to the large cross-sectional area of ​​the material box, there is a large error in the filling volume, which makes the accuracy of the filling volume unsatisfactory; two. It adopts the first-level filling control, that is to say, when the filling of each bottle is about to be completed, because the liquid flow rate is not decelerated, there will be excess liquid flowing out, causing the filling volume to exceed the range of error

[0004] Chinese patent CN201999715U discloses a quantitative filling machine. A measuring cylinder with a cover is installed in the material box to improve the accuracy of the amount of liquid in the measuring cylinder. The liquid level detection device is installed on the periphery of the small diameter raw material measuring tube. Measurement reduces the measurement error and improves the accuracy of the filling volume, but the measuring cylinder can only play a quantitative role, and the liquid is injected from the bottom of the measuring cylinder, which requires a large additional effect, and the liquid level detection device needs to be installed, and the overall mechanism is complicated
