Bottled liquid filling machine: the core equipment of modern production lines


With the continuous advancement of industrialization, the demand for various liquid products is also increasing. From daily beverages and mineral water to liquid products in the pharmaceutical and cosmetics industries, the packaging market for bottled liquids is huge and diverse. In order to improve production efficiency and packaging accuracy, bottled liquid filling machines play an essential role as indispensable equipment in modern production lines. This article will provide a detailed analysis of the working principle, equipment characteristics, application areas, and market prospects of bottled liquid filling machines.


1、 Working principle of bottled liquid filling machine


The bottled liquid filling machine completes processes such as quantitative filling, sealing, and labeling of liquids through an automated control system. Its working principle can generally be divided into the following steps:


1. Bottle conveying and positioning: The bottled liquid filling machine first sends empty bottles to the filling position through the conveying system. The conveyor belt system can achieve automatic transfer of bottles, while ensuring stable and accurate alignment of the bottles with the filling port through mechanical arms or guide rails.


2. Liquid filling: After the bottle is positioned, the filling system will start according to the set filling volume, and the liquid will enter the bottle through the filling head or nozzle. Bottled liquid filling machines can choose different filling methods based on the type, viscosity, and bottle size of the liquid, such as gravity filling, air pressure filling, and quantitative filling.


3. Bottle mouth sealing: After the liquid filling is completed, the bottle mouth will be sealed by an automatic sealing device. The sealing methods usually include heat sealing, pressure sealing, or capping to ensure the sealing of the bottle mouth and avoid liquid leakage or external contamination.


4. Labeling and Printing: After sealing, the bottled liquid filling machine can also be equipped with automatic labeling equipment to accurately label the product on the bottle body. The label may include brand information, production date, batch number, and other information. Some devices are also equipped with coding machines to print the production date and batch number.


5. Finished product output: After filling, sealing, and labeling are completed, the bottles are transported by conveyor belts to the next process, such as quality inspection, packing, or warehousing.
