The filling scale achieves quantitative filling by measuring the weight on the scale. It directly controls based on the weighed 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 filling process to be in a two-stage filling mode, the opening degree of the filling valve is controlled by a double-acting multi-position cylinder to realize the two-stage filling process of the filling valve, which includes high-flow rapid filling and low-flow slow filling.
020-34563445The filling scale set uses a 7-inch touch screen. It integrates 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 liquid Filling machine converts the weight signal from the weighing instrument and obtains the material weight signal, driving 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. During the process, abnormal alarms and interlock protection signals are also controlled.
The feeding value set by the filling scale can be changed in the setting window of the Electronic scale and matched with the start button on the peripheral 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, filling volume, material weight, etc. And it can print out reports or send them to the upper computer for statistical analysis as needed.
The weighing filling machine includes the body, scale, filling feeding device and electrical control box. The body includes a support base and vertical support columns. The filling feeding 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 on the support base in sequence. The weighing sensor is electrically connected to the controller. The support plate has a limit stop rod. On the vertical support column, there is also a sensor for detecting whether there is a packaging barrel 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 the wall of the packaging container 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, and it can also prevent residual filling from dripping and prevent the filling from splashing out during filling.
The weighing filling machine achieves quantitative filling through the weight on the scale. It directly controls based on the measured weight. It uses a two-stage filling valve, a high-precision weighing scale platform, a platform lifting mechanism, a stepper motor and a reducer. By setting the Liquid filling machine of the weighing scale as a two-stage filling, the opening degree of the filling valve is controlled by the two-way multi-position cylinder to achieve the two-stage filling process of large flow rapid filling and small flow slow filling. The stepper motor drives the chain wheel to move the electronic scale platform at a certain speed, keeping the liquid surface and the valve opening at a certain distance. At the same time, a proportional pressure reducing valve and a displacement sensor 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 liquid filling machine automatically feeds empty barrels into the electronic scale platform. The electronic scale platform quickly lifts the empty barrel 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 barrel weight and clears this weight, which is the "zeroing" process. After zeroing, the filling valve immediately starts filling. At the beginning of filling, the fast filling valve is opened, and large flow rapid filling is carried out. As the filling weight increases, the stepper motor drives the electronic scale platform to descend synchronously, keeping the liquid surface and the valve opening at a distance of 15-17 cm. When the filling weight reaches the set switching value (generally 90% of the set weight), the fast filling valve will close, and only the slow filling valve continues to fill. When the filling weight reaches the set target value minus the "spillage error" value, the filling valve closes, and waits for the spilled material to fall into the bucket. Once the weighing platform stabilizes, the system reads and records the data, then the weighing platform drops to its original position, completing one filling process.
