The automated weighing and batching production line was officially born based on this idea. The batching system is a control system for automated weighing and batching equipment used in industries such as cement, steel, glass, coal mining, pharmaceuticals, and feed, which can save a large amount of labor for production and bring huge benefits to the enterprises.
The weighing and batching control system includes various equipment such as raw material storage, transportation, weighing and batching, dust removal, material mixing, packaging and filling, etc., covering multiple types of materials including powdery, granular, blocky, sheet-like and liquid substances; among them, the weighing and batching system, based on industry characteristics and process requirements, combined with material properties, reasonably selects various measurement methods such as single-material batching, sequential cumulative addition of multiple materials, weight reduction batching, weight loss scale batching, belt/screw scale, and bulk material scale.
The main feature is that a medium-sized and small-scale distributed control system is adopted in the system structure, which solves the problem of decentralized control and centralized management; the upper computer and the lower computer are relatively independent, with manual, automatic and semi-automatic switching functions. When connected, they exchange information according to specific protocols; when offline, each scale can independently achieve process control in a closed loop; the upper computer is far away from the operation site, which improves the stability of the system and improves the working environment of the operator; the lower computer uses a programmable controller, which has strong anti-interference ability, simple programming and easy to master, and can operate reliably for a long time in harsh environments; PID regulation is adopted to improve the batching accuracy of the system, and excellent working switch timing can be set according to production requirements, and the material ratio of the batching system can be automatically modified.
The main functions of the ingredient control system solution:
1. Monitoring function: Detect and monitor parameters such as the instantaneous flow rate, daily cumulative, monthly cumulative, and annual cumulative of the material feeding process by the belt scale;
2. The screen display: The operation status of the control parameters during the ingredient preparation process can be shown on the computer monitor, as well as the real-time ingredient curve and table.
3. Printing Management: You can print the ingredient report at any time for storage and retrieval purposes.
4 Communication Function: The industrial control computer can conduct bidirectional data and information exchange with the PLC and the instruments.
5 Data Processing: The system automatically performs calculation and processing on the collected signals, and outputs them to the corresponding control quantities.
6. Control Function: Based on the preset values before operation, it automatically controls the normal operation of the equipment, including PID regulation;
7. Alarm Function: The upper computer will issue alarms in the form of visual displays and audio-visual signals for any parameter exceeding the limit or abnormal equipment status.
