The feeding system is a control device for fully automated, real-time and high-precision feeding, weighing, mixing and packaging of various raw materials strictly in accordance with a certain scientific ratio. The dry powder building aggregate, binder, and additives are evenly mixed, transported to the construction site in the form of bags or bulk, and can be used directly after adding water to the mortar building materials. At present, the signal of the batching machine and the digital signal of the switch bin door of the hopper are connected to the PLC control system, and the batching machine is transmitted through the screw, and the hopper bin door begins to load, and the loading ends. When the control system receives the spiral arrival signal, the data of the batching machine is recorded as real-time weight, and when the signal of the hopper closing the bin door is received, the data of the batching machine is recorded as real-time weight, and then the system calculates the net weight to save, display and upload. When the system receives the spiral arrival signal, the algorithm starts to store the collected data in the defined array. When the next cycle comes, the collected data is compared with the first value in the array. If the value is within the defined threshold, the insertion sorting algorithm is run to store the value in the number of people. Each time the collected value is compared with the first value in the array, and it is determined whether to save according to the result. The continuous values meet the conditions, indicating that the weight of the object on the batching machine is in a stable state, and the flow rate can be obtained. The intermediate value, cycle period and array dimension can be adjusted according to the actual application.

For the material used as the binder in the mixture, the corresponding ash dose is found on the standard curve according to the solution titration consumption of the sample of a certain quality. Through the detected ash dose data, repeatedly adjust the screw conveyor revolution (for cement binder) or belt revolution (for ash binder), so that the ash dose reaches the design dosage. Batching machine with weighing instrument as the core, control other equipment to complete the batching. The raw materials are driven by the winch from the bin to the weighing batching machine, and different materials are transported respectively. The running speed of the winch is adjusted by the frequency conversion governor according to the output voltage of the weighing instrument. The weighing instrument keyboard is used to set the formula and batch of ingredients, the weighing instrument automatically selects the required bin, sends instructions to drive the winch motor, and makes the material fall into the weighing batching machine. The weighing module on the weighing batching machine outputs the weighing signal, and the frequency conversion governor is controlled by the weighing instrument to adjust the winch speed and control the feed amount, so that the end value reaches sufficient accuracy. At the end of the dosing, the automatic door opens, the material enters the mixing machine, the weighing instrument automatically calculates the mixing time, and releases the finished material after the mixing is finished.
