The explosion-proof weighing and Filling machine provides a human-machine interaction interface to complete functions such as control information input, data management, data display, storage, statistics, and reporting. The keyboard inputs the weight of ingredients, generates the weight of various liquids based on the filling ratio of liquids, and transmits it to the PLC through communication. During the filling process, dynamic real-time monitoring is carried out, and information such as the weight of each liquid sent by each slave machine, cumulative feeding amount, and given values of each liquid weight are collected at regular intervals. The information is displayed on CRT ± and relevant database files are formed. Various management files and reports are printed when needed. The Filling system communicates in real-time with the upper computer to ensure the consistency between the data displayed on the interface and the actual data on site. The operation commands and set parameters issued by the operator on the upper computer can be sent to the PLC for execution in real time. The main job of PLC is to receive commands and data sent by the upper computer, control the motor start stop and speed through the frequency converter, detect and control other switch values in the system, collect real-time weight signals of various materials and compare them with the given signals to determine the next control plan, and transmit the weight signals to the upper computer.

The weighing and filling machine adopts a body, a weighing scale, a filling and feeding device, and an electric control box. The body includes a support base and a vertical support column. The filling and feeding device and the electric control box are installed on the vertical support column. The electric control box is equipped with a controller. The electronic weighing scale includes weighing sensors and support plates arranged on the support base in sequence. The weighing scale is electrically connected to the controller. The support plate is equipped with a limit lever in the X-axis and Y-axis directions, and there are also rollers on the support plate. There is also a sensor installed on the vertical support column to detect whether there is a packaging bucket on the support plate. The filling feeding device includes a fixed bracket and a filling pipeline installed on the fixed bracket. The filling pipeline is equipped with an inlet connected to the external filling material pipeline and an outlet for discharging the filling material. A filling gun control device is installed on the filling pipeline, and a pipeline opening and closing device is installed at the outlet of the filling pipeline to control the opening or closing of the filling pipeline. The filling gun control device includes a first cylinder, and a first stopper is connected to the piston rod of the first cylinder to restrict the filling gun. When the piston rod of the first cylinder extends, the first stopper blocks a part of the filling pipeline and plays a role in limiting flow. The pipeline opening and closing device includes a second cylinder, and a second stopper for opening or closing the filling pipeline is connected to the piston rod of the second cylinder. When the piston rod of the second cylinder extends, the stopper leaves the outlet, that is, the filling pipeline is opened. The filling gun control device and the pipeline opening and closing device can both be solenoid valves. There is a feeding cylinder located below the fixed bracket, which is fixedly connected to the fixed bracket through a connecting seat. The piston rod of the feeding cylinder is connected to a feeding hopper. A fixed support plate is installed on the upper and middle front sides of the vertical support column, and two guide rods are installed between the two fixed support plates. The fixed bracket is installed on the guide rods, and a cylinder installation plate is also installed on the two guide rods. A third cylinder is installed between the cylinder installation plate and the fixed bracket, and a rod is installed between the upper fixed support plate and the cylinder installation plate. The upper end of the screw rod is equipped with a screw rod driving device, which drives the screw rod to rotate, allowing the third cylinder and the fixed bracket to move up and down along the guide rods. The action of the third cylinder can move the fixed bracket up and down.
