Semi-automatic batching system can complete the required control tasks by communicating with each slave machine, and it should also have the functions of real-time display of working conditions, formula optimization and management consulting, etc. The data between the host and each slave machine can be used as the data source of the batching system. The data exchange between the host and the slaves and the real-time display module for the control of the slaves are realized. The host issues cycle commands to the slaves, enters into the dosage cycle process, receives the working condition information from the slaves in turn. Real-time dynamic display, and according to the corresponding control program to send control commands to each slave.
020-34563445Weighing and feeding system based on PC and accurate quantitative dosage is a technical equipment integrating machine, electricity, signal processing and dosage. The electrical part is mainly composed of weighing module, weighing instrument, programmable controller (PLC), frequency converter, industrial control machine and printer. During the dynamic weighing process, it accepts the weight signal from the weighing module on the quantitative weighing hopper. When the weight of the material in the hopper reaches the set value, the I/O quantitative signal is output to PLC, which collects the quantitative output signal from the weighing instrument and controls the output frequency of each frequency converter through PLC, so as to control the amount of coarse and fine feeding of the corresponding vibrating Feeder and the opening and closing of the material door of each weighing hopper. The industrial control machine communicates with the weighing instrument through RS232 interface, and the weighing data of each scale will be displayed on the monitoring screen, and the user can adjust the formula on the panel of the weighing instrument or on the operation interface of the industrial control machine.
Automatic Batching system adopts computer automatic control and network technology technology, reaction pot to the production process from the material drying, screening, conveying, measuring, unloading, mixing, discharging to the packaging of the whole process of control and management, reaction pot for the production of improving the operational efficiency and quality of operation. Adopting industrial control machine weighing manager as the core control equipment, the output port of programmable controller controls the relay or contactor of the corresponding equipment and receives the working conditions, the industrial control machine executes the program prepared according to the process requirements, real-time collection of input from the weighing instrument, and controls the action of the corresponding equipment.
The feeder is controlled by PLC at regular intervals, the mixer is always mixing, and the liquid is quantitatively added when mixing, the material bin must be released when the door of the hopper is closed (if the hopper is equipped with weighing scale) and the scale is empty. The hopper will start to release material after the bin is closed in place. External storage tanks and internal silos start to feed material to the screw after a delay, the amount of material to be fed is controlled by the opening of the material door, and the starting and stopping is controlled according to the start and end of the discharge of material from the hopper. All controls are interlocked by PLC, and PLC controls the start and stop.
