The filling scale set is equipped with a 7-inch touch screen, integrating measurement, display, recording, control, alarm, communication, calculation and other functions. It can achieve various control schemes such as single-loop control, cascade control, range division control, ratio control, program curve control, batch control, etc. Through its flexible expression programming function and internal functional modules, the above processes can be conveniently realized within the controller. 

The filling Electronic scale converts the weighing instrument's signal into a weight value, obtaining the material weight signal, and drives the motor to rotate. Combined with the internal cumulative calculation module, the cumulative weight can be calculated and added based on inertia. In principle, the value of closing the motor can be adjusted within the allowable accuracy range. At the same time, the internal control module is used to control the instantaneous weight. Meanwhile, the abnormal alarm and interlock protection signals during the process are also controlled. 

The feeding value set for the filling electronic scale can be changed in the setting window of the electronic weighbridge and is matched with the start button on the peripheral of the weighing instrument to ensure simple and reliable operation. At the same time, the Filling system has both automatic control function and manual function. When necessary, the operator can manually open and close the valves on site. Finally, the system will automatically record and display various data, such as valve position status, feeding volume, material weight, etc. And it can print out reports or send them to the upper computer for statistical analysis as needed. 

The weighing and filling scale system consists of the body, the scale, the filling feed device and the electrical control box. The body includes a support base and vertical support columns. The filling feed device and the electrical control box are installed on the vertical support columns. The electrical control box is equipped with a controller. The electronic scale includes a weighing sensor and a support plate arranged successively on the support base. The weighing sensor is electrically connected to the controller. The support plate is provided with a limit stop rod. On the vertical support column, there is also a sensor for detecting whether there are packaging containers on the support plate. On the support plate, a limit stop rod is set. When the packaging container is placed on the support plate and its wall contacts the limit stop rod, the positioning is completed. At this time, the container mouth is aligned with the filling head, which is convenient, fast and accurate. The filling result is accurate. At the same time, it can prevent the residual filling material from dripping and prevent the filling material from splashing out during filling. 

The packaged electronic scale dispenser achieves quantitative filling by measuring the weight on the scale. It directly controls based on the measured weight and is equipped with a two-stage filling valve, a high-precision weighing scale platform, a platform lifting mechanism, a stepper motor and a reducer, etc. By setting the liquid Filling machine during the material filling process to be in a two-stage filling mode, the opening degree of the filling valve is controlled by the double-acting multi-position cylinder to realize the two-stage filling process of large-flow rapid filling and small-flow slow filling of the filling valve. The stepper motor drives the sprocket to rotate, which in turn drives the electronic scale platform to descend at a certain speed, ensuring that the liquid level of the material and the filling valve opening always maintain a certain distance. At the same time, proportional pressure reducing valves and displacement sensors are added to the hydraulic system of the material extruder to adjust the extrusion pressure of the material, so that the pressure at the filling valve opening can be kept in a relatively stable range. 

The quantitative scale automatically enters the electronic scale platform through the empty bucket. The electronic scale platform quickly lifts the empty bucket to a position 15 cm below the filling valve opening and stops. At the same time, the electronic scale completes the weighing of the empty bucket and resets the weight to zero, thus completing the "zeroing" process. After zeroing, the filling valve immediately starts filling. At the beginning of the filling process, the fast filling valve is opened, and a large flow rate is used for rapid filling. As the filling weight increases, the stepper motor drives the electronic scale platform to descend synchronously, maintaining a distance of 15-17 cm between the ink surface inside the bucket and the valve opening. When the filling weight reaches the set switching value (generally 90% of the set weight), the fast filling valve will close. At this time, only the slow filling valve continues to fill. When the filling weight reaches the set target value minus the "skid error" value, the filling valve is closed, and the system waits for the spilled ink to fall into the bucket. After the weighing platform stabilizes, the system reads and records the data, and the weighing platform drops to its original position, completing one filling process.
