Dosing system is a very important process in the production process of fine chemical plant, and the quality of dosing process is very important to the quality of the whole product. The automatic batching control process is a multi-input and multi-output system, where each batching and conveying production line is strictly coordinated and controlled, and the material level and range are timely and accurately monitored and adjusted. The system consists of programmable controllers and equipment to form a two-level computer control network, through the field bus to connect the field weighing instruments, control computers, PLCs, inverters and other intelligent degree of fast processing speed equipment. In the automatic dosage production process, the main material and auxiliary materials according to a certain proportion with the dosage equipment to complete the measurement of the material conveyor conveyor, PLC is mainly responsible for the conveyor equipment, weighing process for real-time control, and complete the system failure detection, display and alarm, while outputting signals to the frequency converter to regulate the speed of the role of the motor.

Automatic Batching system through the combination of load cell, weighing instrument, multi-way junction box (including amplifier), control system can realize the weighing and measuring of the batching system, thus the control system, the user can directly access the PLC to realize the multi-range control and automatic control of the system, the terminal control system. Collect high precision weighing data for you. Provide a complete control program, integrated weighing display, storage of component parameters, data acquisition and processing, charging and discharging, the instrument can meet the requirements of the user to control the production of the high degree of integration. The weight signal output from the load cell is mainly collected, and after internal filtering and processing, the output is transmitted to PLC, which completes the other control parts.

The feeding system stores the materials to be proportioned in the material storage warehouse, and then conveys them to the weighing mechanism through the conveying equipment. The weighing mechanism measures the material accurately to ensure that the proportion of the material is accurate. The mixture is transported through the pipeline to the mixing equipment, where it is mixed thoroughly. The control system detects the quality of the mixed material and adjusts the mixing time, speed and other parameters to ensure the stability of the final product quality.

The feeding system accurately proportions all kinds of raw materials according to the production demand, the mixing system fully mixes the raw materials, the blending system ensures the uniform distribution of raw materials, the transportation system is responsible for delivering the finished products to the designated place in time, and the packaging system packages the finished products according to the specifications. The operation process of the automatic batching line is as follows: firstly, the operator inputs the production instruction, the system will automatically batch the ingredients according to the instruction, and the mixing, blending, transportation and packaging will be carried out according to the preset program. Finally, the finished products will be tested for quality, and the products that meet the standard will be output, and the whole production process is highly automated.
