Weighing Filling machine adopts high-precision electronic weighing technology and automatic filling technology, so as to achieve high-precision dynamic metering filling of liquid media, its metering accuracy is not affected by pressure, temperature, bubble and other factors, with simple installation and debugging, easy use and maintenance, high filling accuracy, high degree of automation. It is mainly composed of empty drum conveying roller table, nitrogen charging device, charging device, Weighing system, solid drum conveying roller table, electrical control system, pneumatic capping machine, filling pipeline, etc.

When the barrel reaches the filling position, the automatic filling machine senses the filling barrel near the switch, transmits the induction signal to the PLC, the PLC controls the conveying motor to stop, the lifting cylinder begins to rise under the control of the PLC, and drives the roller arm structure to rise to the maximum position of the cylinder stroke, the lifting cylinder stops rising, and the synchronous motor starts to drive the roller arm to move. The filling barrel can be rotated under the drive of the roller arm. The photoelectric sensor above the barrel mouth and the filling head are on the rotating trajectory circle of the barrel mouth, and the filling barrel rotates to the right below the photoelectric sensor. When the photoelectric sensor senses the edge of the filling barrel mouth, the signal is transmitted to the PLC, and the PLC will stop the synchronous motor movement according to the signal of the photoelectric sensor. When the barrel mouth is detected, the cap suction device rotates to the top of the filling barrel mouth under the drive of the cylinder, draws the lid of the filling barrel, and returns to the original position after the cap suction action is completed. When the barrel cover is absorbed, the quantitative filling process begins. The PLC controls the rodless cylinder to drive the filling gun into the filling barrel for liquid filling. The weighing module can sense the change of weight in the filling barrel to realize the quantitative filling of liquid. After the liquid filling is completed, the instrument will transmit the filling end signal to the PLC, and the PLC will finish the quantitative filling process according to this signal. The PLC control rodless cylinder drives the filling gun to the initial position, and the cap suction device rotates to just above the position of the mouth of the filling barrel and places the cap on the mouth of the filling barrel. The conveying motor starts and transfers the filled filling drum to the designated position.
