The automatic batching and weighing control system is defined as a device controlled by computer, which can accurately calculate the proportion of a variety of materials, and accurately weigh and mix. The basic principle is as follows:

1. the batching system is composed of multiple batching silos, conveying system and weighing system. Various materials are stored in the corresponding batching bin according to the specified proportion.

2. the computer is responsible for controlling the whole batching system. It receives the process formula as input, and formulates the batching scheme according to the proportion of each material in the process formula.

3. the computer opens the discharge door of the corresponding batching bin by issuing a command to trigger the work of the material conveying system and convey the corresponding materials to the metering system.

4. in the metering system, the discharge door of the batching bin will open for a period of time, the material will be weighed by the sensor, and the weight information will be fed back to the computer.

5. the computer will compare the feedback weight information with the formulated batching scheme to determine whether the required weight is reached. If the requirements are not met, the metering time will be readjusted until the required weight meets the requirements.

6. after all materials are mixed evenly in proportion, they are sent to the next production process.

The automatic batching and weighing control system adopts advanced technologies such as computer control, sensor detection, weighing technology and automatic control. It has the advantages of accurate proportioning, rapid response to production changes and high-precision weighing, and is widely used in chemical industry, food, medicine and other fields.

The heavy batching system can realize the following functions:

Monitoring function: detect and monitor the instantaneous flow, daily accumulation, monthly accumulation, annual accumulation and other parameters in the batching process of the belt weigher;

Screen display: the operation status of relevant control parameters in the batching process can be displayed through the computer display, as well as the real-time batching curve and table;

Print management: the batching report can be printed at any time for saving and querying;

Communication function: two way data and information exchange between industrial control computer and PLC and instrument;

Data processing: the batching system can automatically calculate and process the collected signal and output it to the corresponding control quantity;

Control function: according to the corresponding set value before operation, automatically control the normal operation of the equipment, including PID adjustment;

Alarm function: the upper computer will alarm for various parameter overruns or abnormal equipment status in the form of picture and audio-visual signal. call
