The automatic plug Filling machine adopts a human-machine interface, and the display LCD module is T6963C produced by Delta. The P1, P2, and P3 ports of the main control chip AT89C52 are used as data port lines for data exchange with the outside. The EA pin is connected to the+5V power supply, the PSEN pin is connected to the OE terminal of the external 12C887, and the ALE pin is connected to the OE pin of the 74 series driver chip. T0, T1 timer mode, T2 uses count reset mode. In order to facilitate user operation, the weighing control system adopts key reuse in the keyboard settings of the filling machine. Through software settings, the key functions are different on different display interfaces. The clock function of the control system is completed through the DS12C887 chip, which has a perpetual calendar and can set the system running time. At the same time, the system can set a password. After reaching the running time, enter the password and the system can work normally. The weighing and filling machine has developed a filling management system using SOL+WINCC software. Using computers to implement monitoring and control functions, using programming software to control process and equipment probe signals, liquid level, pressure, mixing, current signals, pump and other facilities' status, start stop and other equipment data, and forming causal conditions with the Filling system process to achieve logical interlocking control.

The automatic filling machine is installed on the machine, and the container can be moved on the assembly line; The bracket is fixedly installed on the machine; The liquid storage frame is fixed and installed on the bracket with bolts; The filling head is connected to the interior of the liquid storage frame through a pipeline; The motor is fixedly installed on the upper part of the liquid storage frame, and the rotating shaft of the motor is connected with a cross plug rod; The rotating disc is mounted on the cross shaped insertion rod, and a connecting part is connected to the rotating disc as a whole. The connecting part has a cross shaped hole inside, and the side facing away from the connecting part is connected to the first defoaming needle as a whole. The rotating disc 7 is made of liquid with a density lower than that inside the liquid storage frame. The cross shaped insertion rod passes through the cross shaped hole and slides in contact with the connecting part. The cross shaped insertion rod can not only serve as a positioning tool for the rotating disk, allowing it to move up and down along the cross shaped insertion rod, but also transmit torque. The motor can drive the rotating disk to rotate through the cross shaped insertion rod. The bracket is fixedly connected to a moving cylinder, and the moving part of the moving cylinder is connected to a connecting rod. The connecting rod is fixedly connected to a moving plate, which is integrated with a defoaming cone. After the liquid is filled into the container, the moving cylinder drives the moving plate to move downward through the connecting rod until the defoaming cone comes into contact with the liquid surface, playing a role in defoaming the liquid inside the container. The distance of movement is related to the height of the container and the volume to be filled. The moving plate is provided with a through-hole, and the liquid passes through the moving plate through the through-hole. There is a downward pressure cylinder installed on the machine, and the moving part of the downward pressure cylinder is connected to a basket and bucket cover. The downward pressure cylinder can drive the basket and bucket cover to move up and down, so as to cover the container. The quantitative filling machine places the container on the assembly line and moves it on the assembly line. The liquid is first stored in the liquid storage frame, and then enters the interior of the container through the filling head. The motor drives the rotating disk 7 to rotate, defoaming the liquid inside the storage frame. After the liquid inside the container is filled, the moving cylinder drives the through-hole to move downwards until the defoaming cone contacts the liquid surface, and defoams the liquid inside the container. After filling is completed, the downward pressure cylinder drives the machine assembly line to move downwards to cover the container.
