After the Broken 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 Three-dimensional 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 metering mixer consists of industrial computer, PLC, industrial weighing control terminal (LYNX), frequency converter, vibration motor, screw feeder, weighing module and so on. The industrial computer provides man-machine interactive interface, and completes the functions of controlling information input, data management, data display, storage, statistics and reports. All the control work is completed by PLC. During the system operation, PLC communicates with the upper computer in real time, so as to ensure the consistency between the data displayed on the interface and the actual data on site. The operating commands and setting parameters issued by the operator on the upper computer can be sent to the PLC for execution in real time.

The Activation screw mixer inputs the weight of the ingredients through the host, generates the weight of various materials according to the ratio of raw materials, and transmits it to the PLC through communication. During the dosing process, dynamic real-time monitoring is carried out, other switch quantities sent from each slave are collected regularly, the weight signal of each material is collected in real time and compared with the given signal to determine the next control scheme, and the weight signal is transmitted to the upper computer.

The Warehouse pump vacuum mixer adopts a master-slave batching system with PLC as the main controller and industrial computer as the upper computer, which can meet various requirements of the system and overcome the disadvantages of the above two systems. Operators can input and modify the formula through the keyboard and CRT display, dynamically monitor the production process of batching, and print batching results and production reports in time, so as to realize scientific batching production automation and management. Information such as the weight of each material, the cumulative blanking amount and the given value of each material are displayed on CRT, and relevant database files are formed. When necessary, various management files and reports are printed out.

The Error-proofing mixer adopts a master-slave communication structure, with one-to-many communication between the master and slave machines. The master is in the leading position to realize the communication management and control of each slave machine. The RS-232 asynchronous communication port of the industrial computer is connected with PLC after level conversion, forming a physical channel for communication between the upper and lower computers. The upper system is a master-slave bus type industrial local area network, with the upper computer as the master station of the industrial local area network communication, and all other PLCs connected to the network are slave stations. The upper computer adopts polling method, allocates the right to use the bus, and communicates with the slave stations one by one in a certain order.

The weighing system provides man-machine interactive interface, and completes the functions of controlling information input, data management, data display, storage, statistics and reporting, etc. The industrial computer inputs the weight of ingredients through the host keyboard, generates the weight of various materials according to the proportion of raw materials, and transmits them to PLC through communication. In the process of batching, dynamic real-time monitoring is carried out, and other switching values in the detection and control system sent by each slave machine are collected regularly, and the weight signals of each material are collected in real time and compared with the given signals to determine the next control scheme, and at the same time, the weight signals are transmitted to the upper computer.

The process of weighing system is mainly the batching metering and feeding process. In batching metering process, firstly, the time of discharging from the material feeder to the metering tank is controlled according to the weighing requirements, so as to control the amount of material entering the metering bin, and then the time of discharging from the feeder to the metering tank is controlled according to the material proportioning requirements, so as to control the weight entering the metering tank, thus completing the weighing process once until the specified weighing times for each batching are completed.

The High-speed mixer mainly completes batching metering and feeding process control. According to the user login level preset by the operator, PLC manually sets and adjusts the set parameters such as weighing times, counterweight, ratio, impact difference, etc. At the same time, the actual value of each batching and the actual value of under-value, as well as the next target value obtained by PLC operation, weighing times, times to be weighed, ratio, etc., and the system also requires equipment control requirements such as batching interlocking, downward interlocking and upward interlocking.
