The automatic Filling machine uses the working principle of weighing to control the filling amount, controls the opening time of the filling valve through the programmable controller PLC, and the material flows into the container to be loaded by itself (or through the pump to feed). The filling department of the machine controls the filling flow rate through the manual valve + double fast and slow filling pneumatic ball valve, and the double stroke switch of the filling gun head. When filling, it can realize the action of fast filling first, slow filling later, and the filling action of slow filling first, fast filling midway, and finally flood filling. After filling, automatic screw cap and waterproof cap capping action can be carried out.

The automatic filling machine obtains the filling data (production time, filling weight, recording time) on the production line in real time, and stores the data into the database, and then manages the data. Judging whether the filling production meets the requirements according to the production record data, all users including the administrator can only modify the qualification mark and remarks information of the data. Statisticians and administrators can query and print the data by day, month and year, because the database stores data in file form. The backup of the database can be achieved by copying the database file to a new directory.
