Description

Technical Field

[0001] The utility model relates to an auxiliary external filling mechanism of a filling machine. Background Art

[0002] There are various types of filling machines that can meet the filling needs of various styles of items. One of them is a filling machine for milk. When filling milk, it is generally placed in a paper plastic cup, and the milk is poured into the paper plastic cup through a special filling mechanism, and then the cup is sealed. The filling structure of the filling machine generally includes an auxiliary mechanism and a main filling mechanism. Usually, the role of the auxiliary mechanism is greater than that of the main filling mechanism. The auxiliary filling mechanism needs to control the injection volume. However, the auxiliary mechanism and the main filling mechanism of the existing filling structure are integrated into an integral structure, and there is no obvious separate design in production or use. The space occupied by the auxiliary mechanism when installed in the filling machine is very large, which invisibly increases the volume of the filling machine. At the same time, multiple structures are softened together, which increases the difficulty of installation and maintenance, and is also not conducive to management and environmental hygiene. Therefore, it is necessary to design an auxiliary external filling mechanism for the filling machine to facilitate the use of the filling machine. Utility Model Content
