The weighing and mixing machine is inputted into PLC through 16-bit high precision A/D converter module, and PLC automatically controls the whole batching and weighing process, data processing and alarm output of the weighing system through programming. The data parameters and operation of dosage are directly controlled by touch screen interface. The weighing system is connected to the computer through a 485 communication module to form a network, and the computer monitors the system and processes the data.

Inverter mixer through the human group configuration monitoring system and PLC program to load into the weighing and batching truck materials for weight, flow control, so as to achieve accurate measurement and batching. As a dynamic continuous measurement and batching of the whole machine type automation control device, the system can also provide accurate measurement data and control means for the production control and management of various industrial sites.

After the mixer reads it through PLC communication, the corresponding operation is performed. At the same time, PLC moves the monitoring signals to be collected by the touch screen into the communication storage area, and the touch screen can be monitored on the PC by reading the data, and the whole system is connected in series through pressure elements and weighing modules, so as to realize industrial automation, improve transportation efficiency and effectively prevent dust leakage, providing good environmental protection for field workers.

The weighing mixer is composed of some pneumatic and mechanical mechanisms, such as positioning mechanism, front silo supporting mechanism and conveying mechanism, etc. The cylinder is equipped with an in-place detection device. The control system consists of operation panel, plc system, weighing module, LCD screen, operation keyboard, process control point and upper computer. The weighing system ensures the accurate delivery of materials, reads the data of electronic scales, and displays the data in real time on the special plane display screen. At the same time, the data are sent to the upper computer to form a table for the batch data such as materials and density on the production line and analyze and process it.

The operator of the mixer inputs the proportion of each raw material, the machine will calculate the weight of each raw material by combining the weight of each ingredient, and then control the opening and closing of the metering valve to distribute the raw materials to the weighing hopper, when each raw material is completed in accordance with the proportion of the raw material, the raw material in the weighing hopper will be discharged to the lower part of the agitator for stirring, and after the completion of the mixing, the whole process is complete.

Mixing system is a kind of intelligent weighing system integrating control and management, with superior performance, stability and reliability. The product takes imported high-grade industrial computer as the mixing host, and combines with operation desk, analog screen and scale body to form a complete control system, and flexibly composes a machine and a scale and a machine and a scale according to the user's technological needs, and the selection of this system can greatly improve the enterprise's production efficiency and management ability.
