The liquid Filling machine is an automated and quantitative weighing device that uses mechanical, electrical and pneumatic systems to achieve the transfer of liquid materials from the storage unit to the container. It uses PLC control processing to achieve full automation and intelligence in the filling process. It can complete actions such as distance increase, distance decrease, diversion, elevation and flipping for batch-filled containers arranged in a regular or irregular manner, according to the filling process requirements, and transfer them to the filling execution mechanism to complete the cylinder elevation and filling. It adopts anti-dripping and leakage devices, quick-fit clamps and quick-fit water nozzle connectors; SMC rodless cylinders. The spray gun device can rise with the increase of the liquid level, ensuring that the spray gun can perform filling at a certain position of the liquid surface. The weighing filling machine is equipped with two operation modes. In the automatic mode, after starting the system, the motor automatically starts to run and drives the conveyor belt to operate until the stop switch is activated, the motor stops running. Or when the Electronic scale detects that there is an iron bucket on the production line and stops, it is in the filling state, then the conveyor belt stops running. After the iron bucket is filled, the conveyor belt automatically resumes operation until it receives the next stop signal, and this cycle repeats. In the manual operation mode, the system is controlled by a switch control system. When the switch is turned on, the system starts, the iron bucket reaches the filling position, and the system stops. Release the start switch and press the filling switch, then the filling action is activated, while the electronic scale starts the measurement work, controlling the filling target volume, and stops filling when the target volume is reached. Here, press the system start switch, and the system starts the operation mode. 

The quantitative filling machine is composed of a storage tank, a mixing device, a liquid level sensor, and a temperature control/insulation component. The liquid level sensor continuously monitors the material level. When it drops below the lower limit value, a replenishment signal is triggered to prevent material shortage. The temperature control component maintains the material viscosity stable through heating or insulation, with the PLC as the core. It is combined with a touch screen, sensors (photoelectric, pressure, liquid level), servo motors, and pneumatic components. After the PLC presets the filling parameters, it collects real-time signals through the sensors to control each actuator to move in sequence. The touch screen is used for parameter setting, status monitoring, and fault alarm. After being organized in a unified direction, it is sent to the conveyor container system: including a conveyor belt, a container Sorting machine, a positioning mechanism, and an anti-tilt device. The container sorting machine locates the disordered empty containers. The positioning mechanism detects the container position through a photoelectric transducer. The anti-tilt device prevents the containers from tipping during transportation, ensuring that they precisely stop below the filling station. 

After the empty containers are sorted by the bucket machine, the automatic filling machine transports them uniformly along the conveyor belt to the filling area. At this point, the photoelectric sensor detects that the container has reached the preset position and immediately sends a signal to the PLC. The PLC then controls the conveyor belt to stop and activates the positioning mechanism, positioning the container directly below the filling head to ensure precise material injection during filling. The liquid material in the storage tank is transported through the feeding gear pump, depending on the viscosity of the material, to the filling main pipeline. To ensure the filling accuracy, pressure stabilizing valves and flow sensors are installed in the pipeline. The pressure stabilizing valve can balance the pressure fluctuations in the pipeline and the pressure changes during feeding, and the flow sensor provides real-time feedback on the material flow rate. The PLC adjusts the rotation speed of the feeding pump based on the feedback signal to ensure a stable material transportation rate. For low-viscosity materials, gravity self-flow combined with an electromagnetic valve can be used for control; for high-viscosity materials, a combination of heating, insulation, and high-pressure pump transportation can be adopted.
