Description

TECHNICAL FIELD

[0001] The utility model belongs to liquid filling equipment technical field relates to a filling unit. BACKGROUND

[0002] In the rapidly developing consumer goods market, the packaging technology of liquid products plays a crucial role. From beverages, cosmetics to pharmaceuticals and many other fields, efficient and precise filling processes are the foundation to ensure product quality and meet consumer demand. As the core equipment to achieve this goal, filling machines have undergone an evolution from simple manual operation to highly automated systems. Early manual filling machines rely on the experience of operators to control liquid flow and filling volume. Although this mode is flexible, it has obvious limitations, such as low production efficiency and unstable filling accuracy.

[0003] With the continuous improvement of industrial automation level, automated filling machines have emerged. These new devices use advanced sensing technology and control systems to achieve precise control of liquid flow speed and filling volume, greatly improving production efficiency and product quality. However, traditional automated filling machines mostly use static filling methods, which means that after completing the filling of a container, the container must be removed and replaced with a new empty container before starting the next filling cycle. This "stop-filling-stop" working mode, although it improves production efficiency to some extent, still cannot meet the growing market demand.

[0004] In order to overcome the limitations of static filling methods, the industry has begun to explore the application of multi-head filling technology. Multi-head filling machines can simultaneously fill multiple containers at the same time, greatly increasing the number of fillings per unit time. This innovation significantly improves the flexibility and production capacity of the production line, especially when handling a large number of orders. However, even with the support of multi-head filling technology, when a group of containers is filled, a certain amount of time is needed to remove them from the filling area and send a new group of empty containers to the preparation position. The waiting time in this process has become the main bottleneck limiting the overall improvement of filling efficiency. SUMMARY
