The metering Filling machine controls the feeding of empty barrels, filling valve filling, filling weighing, and finished product output to complete one filling process. A feeding mechanism is designed on the storage tank of the filling equipment, and two values are set for the position of the floating ball inside the filling: the lowest value and the highest value. When the floating ball position is at the lowest value, feeding is carried out, and when the floating ball position rises to the highest value, feeding is stopped. The filling valve is driven by a dual station cylinder and is filled in two stages. When the automatic filling machine sends the bucket into the roller conveyor, the photoelectric switch detects that the bucket is in place, and the bucket pushing cylinder moves. The filling machine pushes the empty bucket onto the unpowered roller on the weighing mechanism. When the photoelectric switch detects that the bucket has reached the filling position, the filling valve is fully opened to start filling. When the filling weight reaches the set initial weight, the filling valve is half opened for filling; When the filling weight reaches the set weight, that is, the required filling weight, the filling valve is fully closed. The bucket pushing cylinder moves to push the next empty bucket to its position, and this empty bucket pushes the filled bucket onto the conveyor for transportation. The quantitative Liquid filling machine adopts a scheme of adjusting the actual weight control, and sets its parameters according to the frequency converter operation mode to achieve the purpose of automatically adjusting the speed. In order to ensure the accurate and reliable operation of various devices in the filling process, PLC programmable controllers need to control various Weighing modules, relays, switches, and solenoid valves through PLC programs. Integrate information technology accessory devices, such as printers, scanners, RFID and other information recognition devices, to provide identifiable information for materials entering the weighing process. The automatic filling machine adopts the DELL industrial control computer WINXP operating system, and uses a programmable controller to design process control such as filling scanning and filling management. Based on the relevant database information services, the monitoring interface of the filling production line is installed using Kingview software. The PLC system provided by Kingview is used to connect with the on-site control. Adopting an intelligent multifunctional panel, the human-machine interface is simple, suitable for configuration, and easy to modify, achieving a complete human-machine dialogue state. The PLC control system and operation station can communicate quickly through the RS-422/485 interface.

A liquid filling machine is a machine that measures and fills liquid by controlling the volume of liquid filled into the filling container. The liquid filling machine includes an input device for feeding empty barrels, a fixture device for fixing the position of empty barrels, a filling device for filling liquid into empty barrels, and an output device for outputting barrels containing liquid. When filling, first place the empty container on the input device, fix the empty container on the filling device by the fixture device, and fill the liquid by the filling device. After filling is completed, transport the container containing the liquid to the output device, place the next empty container in the fixture device, and then proceed with filling, and so on. The automatic liquid filling machine includes an input device, a filling device, and an output device, both of which include a frame, a conveyor belt, and a power source for driving the conveyor belt. The filling device includes a base, on which a filling mechanism, a feeding mechanism for transporting containers, and a fixture mechanism for aligning empty containers with the filling mechanism are installed. One end of the feeding mechanism is connected to the input device, and the other end is connected to the output device; The filling mechanism includes a first filling head and a second filling head, as well as a displacement member that transfers the container from the first filling position to the second filling position; Each filling head corresponds to its own raw material storage tank, and each filling head is equipped with a lifting drive component; The displacement component includes a displacement bracket that supports the container and a displacement driving element. The fixture mechanism is set on the displacement bracket, and the fixture mechanism includes a fixture that holds the container and a lever that pushes the container into the fixture; The displacement component is installed on the lifting platform, which is connected to the lifting cylinder. When the lifting cylinder rises, the container disengages from the feeding mechanism; After the lifting cylinder is reset, the container falls into the feeding mechanism. Each raw material storage tank is equipped with a fast liquid filling cylinder and a slow liquid filling cylinder. The displacement bracket is equipped with a weighing scale that senses the actual liquid filling weight. The electronic weighing scale is connected to the controller, and the controller is pre-set with a slow liquid filling starting value and a liquid filling threshold. When the actual liquid filling weight reaches the slow liquid filling starting value, the controller stops the fast liquid filling cylinder and starts the slow liquid filling cylinder; When the actual liquid addition weight reaches the liquid addition threshold, the slow liquid addition cylinder stops. The weighing and filling machine drives the rotating cylinder through a displacement component. When the rotating cylinder is in the first position, the fixture holds the container aligned with the first filling head; When the rotary cylinder is in the second position, the fixture holds the container aligned with the second filling head. The rotation amplitude of the rotary cylinder is 90 degrees. The metering filling machine uses a pneumatic fixture as the lever, including a lever cylinder and a rod connected to the lever cylinder. The lever cylinder is fixed on the displacement bracket, and the frame is equipped with a photoelectric detection switch. The lever cylinder is controlled by the photoelectric detection switch, which is in a normally open state. When the container reaches the lever, the photoelectric detection switch is blocked, the lever cylinder is activated, and the lever pulls the container into the fixture.
