Weighing mixer (batching equipment) is a very important process in the process of factory production, and the quality of batching process plays an important role in the quality of the whole product. The automatic batching control process is a multi-input and multi-output system. All batching production lines are strictly coordinated and controlled, and the material level and flow are monitored and adjusted timely and accurately. The system consists of a programmable controller and a weighing sensor, and the Batching system is connected with field instruments, control computers, PLC, frequency converters and other devices with high intelligence and high processing speed through field buses. In the process of automatic batching production, the main materials and auxiliary materials are matched in a certain proportion, and the materials transported by the pipeline are measured by the weighing sensor. PLC is mainly responsible for the real-time control of conveying equipment and weighing process, and completes the system fault detection, display and preview, and at the same time outputs signals to the frequency converter to adjust the speed of belt conveyor.

Measuring dosing machine In order to realize the uniform mixing of individual weighing places, the Weighing system can provide a paddle-type mixing device, which can realize the metering and proportioning transportation of various materials, and has the characteristics of accurate metering, high speed, no abrasion to materials and high metering accuracy. It has the characteristics of high degree of automation, simple operation, environmental protection, accurate feeding and high proportioning accuracy. Through the computer control center, the whole production process can be effectively controlled, and the possible errors caused by human operation can be eliminated. It is widely used in pharmaceutical, food and chemical industries.

The weighing control system measures the speed of the spiral operation, converts it into corresponding pulse signals, and sends them to the computer after photoelectric isolation. The computer communicates with PLC to detect the flow rate and the running state of the feeding motor. After the instantaneous flow is calculated by the computer, it is compared with the required flow, and the computer outputs the corresponding speed regulating signal. After photoelectric isolation, DA is converted into a speed regulating signal of 4-20mA, and the operating frequency of the frequency converter is adjusted, so as to control the operating speed of the feeding motor and achieve the purpose of controlling the feeding amount.

The automatic Feeder calculates the formula according to the detection data and inputs it into the computer system through the man-machine interface or computer network. The computer control system automatically calculates the supply ratio of each raw material according to the detection data and the process formula, and then the PLC control system synthesizes the supply speed of each raw material supply system to accurately and continuously complete the raw material ratio according to the process sequence.

Through pipeline transportation, the PLC system processes the information such as weighing module or flowmeter to control the actions of automatic valves and delivery pumps, so as to realize accurate and safe feeding, effectively solve the problem of material pollution in the workshop and create a clean and tidy production environment for enterprises. The weighing mixer (batching equipment) adopts PLC control scheme, which has the advantages of powerful function, high reliability, low cost and easy maintenance, greatly improves the batching accuracy, is convenient for microcomputer control of metering, realizes networked production management, and has achieved good economic benefits through putting into operation.
