The automatic batching system of the hopper is designed based on the multi-station control requirements, selecting the core of the system control circuit, the weighing sensor, the proportional valve, and the peripheral circuits. The weighing system mainly consists of the weighing module, the material tank, the pneumatic conveyor, and the gas pressure control proportional valve with feedback function. To enhance the stability and reliability of the system, by comparing the input signal and the output signal (pressure) difference, the supply pressure is continuously adjusted under the action of the internal control loop, so that the output pressure is basically equal to the set value. And it is transmitted to the PLC through the Modbus protocol.

Automatic discharge system for a variety of different types of materials for conveying, proportioning, heating, mixing and finished products of the entire production process of automatic production lines. Control the action instructions of each part of the ingredients to fully complete the conveying of materials, accurate ratio, mixing, transportation and other processes. Through the material conveying device, all kinds of materials are automatically transported to the silo, and then automatically weighed in proportion and accurately, and then the mixed materials with a good ratio are automatically transported to the silo for mixing, and then automatically discharged after mixing.

The weighing and discharging system will reflect the running status of loading, batching, feeding and related equipment in the form of dynamic pictures according to the actual process of batching technology. When there is an over-limit fault during operation,  will appear Chinese character alarm warning, and start the alarm (sound and light), or stop the machine, or change the warehouse, and analyze the control status of the operation data. The dynamic batching process of the system is reflected by different color histogram.

The anti-roll weighing sensor is accumulated through the junction box and transmitted to the weighing instrument, which displays the weight of the material in the current weighing in real time through A/D conversion. The displayed weight data is transmitted to PLC through serial communication, and the PLC compares the collected weight of the weighing module with the weight set in the touch screen (or computer) of the electronic scale to control the action of the whole reaction kettle. It adopts high-performance configuration software, has a complete Chinese interface, and has real-time data display, flow and temperature control curves, alarm and operation records, complete production reports and other management functions.

Liquid filling machine is mainly composed of filling management, metering and transmission control modules. Profibus system configuration, with PLC controller as the main station and ET200 distributed I/0 as the slave station, to realize the control of electronic scale, frequency converter and centrifugal pump, and to monitor the liquid level of each barrel and the manipulator. Complete the status monitoring, alarm display and manual operation of the metering and conveying process.

Blending Weighing mixer for additives and pre-mixing unit, PLC as the main control of the unit, weighing module to collect the weight of the material in the mixer and should have the position (prompted when the material is lost). Limit switch, when the lifting action reaches the position, it should be signaled at the appropriate position. Analog output signal, 4-20mA to 4 valve switches to control the opening, with S type tension to collect the material position and close the valve when the weight reaches the required dosage weight. Has a communication circuit module whose function is to communicate with the console. The communication data is bi-directional and is required to receive information from the console about the specific gravity of the material and the weight distribution of each material mixer.

By using the upper computer monitoring system, the Merge weighing mixer can complete the configuration, debugging, online correction of detection parameters and setting of control parameters, the weighing transmitter is used to detect the change of material level in the material batching tank, and the volume and weight of the amount of material in and out is obtained by using the cross-sectional area of the measuring tank.

The liquid filling system is digitally processed by a computer or a dedicated image processing module, which performs the recognition of size, shape, color, etc. based on the information of pixel distribution, brightness and color of the image. The weight of the converted liquid is transmitted to the metering and filling mainframe through a functional relationship measured by the weighing module, and this data is compared with the mainframe's rapid collection, real-time processing, and the settings of the corresponding components in the recipe.

The wireless weighing fork is equipped with a weighing console on the electric forklift, and the weighing instrument is installed on the console. The data lines installed with weighing sensors at the lower parts of the two fork support legs are connected with the digital instrument. When the elastic body adopting digital weighing is subjected to force from the stress direction (such as the gravity of goods), the elastic body generates corresponding micro deformation, which is transmitted to the digital weighing instrument through the force transmission mechanism, and the gravity signal output by the sensor is amplified and filtered. It is sent to an A/D converter to be converted into a digital signal, and the microprocessor calculates the weight value according to the mechanical mathematical model. When the forklift mast is in a vertical state, the weighing data is prompted to be read, and the digital weighing LED displays the results. The real-time data is uploaded to the computer control room by the weighing instrument through wireless.
