The automatic dosage system has a mechanism of mutual monitoring between the computer and the weighing instrument and various alarm mechanisms, with animation and PID control functions. The dosage can be operated by clicking on the mouse. The dosage ratio can be changed at any time. When changing the ratio of one material, the other ratios will be automatically adjusted according to their original ratios, which ensures that the total dosage ratio is 100%, thus guaranteeing the quality and yield of the products.

The weighing and dropping system realizes the process control of batching. According to the need of batching, various control function program modules and control subroutines are designed in the control software. It mainly includes "control system state initialization", "automatic work control", "manual work control", "automatic batching", "state test", "fault detection" and so on. The dosing control software follows the automatic control and manual control modes. In order to improve the performance of the batching control system, improve the accuracy and speed of the batching system, and ensure the reliable operation of the control system, effective measures are taken.

Weighing and discharging system in is an organic whole, storage unit, dosing unit, control unit is the three inseparable basic units, is to ensure that the flow of material dosing of the necessary conditions. The basic unit of material and conveying link in the material changes will have an impact on the flow. Batching control not only rely on the improvement of the regulating device and the optimization of the control software to continuously improve the quality of the dosage regulation, but also with the dosage process is inextricably linked to the dosage process, only from the dosage engineering point of view, in order to grasp the direction of the development of the dosage control, to meet the modern industrial automation of the requirements of large-scale production.

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 reactor control system controls the dosing according to A certain proportion, at the same time gives the feeding system according to the material level information of each reaction tank, sets the relationship between the ratio of raw materials and the arrangement sequence of the total feed quantity meter, sets the weight of the equipment under each reaction tank through the communication of the upper computer, and sends the weight signal and speed signal to the weighing instrument after the weighing system is started. Instantaneous flow and accumulation are calculated and displayed in the field weighing instrument. Self-tuning operation is carried out according to the parameters set by the user. If there is a deviation between the set value and the current value, the PLC analog module will adjust according to the need.

The feeding system adopts Siemens PLC to control the automatic operation of all its interlocking devices (start-stop, interlocking, position switching and other operations), and the upper computer is programmed by Siemens WINCC configuration software. The whole configuration operation screen is embedded into the whole weighing system, and the operation of equipment start-stop operation, operation display, fault inquiry record and maintenance are carried out. The system has the characteristics of friendly interface, concise operation and reliable operation.

Intelligent batching system usually refers to a system in which a reaction kettle is used as a weighing container, and a variety of raw materials are added and mixed in turn during the stirring process according to preset procedures and weight values. A batching system that groups a variety of materials according to the similarity of weighing values, adds them into different weighing containers for measurement, and then mixes them together. Its characteristics are: fast weighing speed, high measuring accuracy and moderate investment.

The reaction kettle is equipped with a weighing module below the silo, and the automatic batching system completes the conveying and metering of materials. The material falls from the inlet to the weighing reactor, and its weight signal and speed signal are sent to the weighing instrument. The weighing instrument displays the instantaneous flow rate and accumulated material transportation amount obtained by calculating and processing the load weight electric signal and speed signal on the weighing display respectively.
