The sorting automatic Batching system is a control device that enables the full automation, real-time, and high-precision feeding, weighing, mixing, and packaging of various raw materials in strict accordance with certain scientific ratios. A mortar type of building material that is uniformly mixed with dry powder building aggregates, binders, and additives, and transported to the construction site in bagged or bulk form, and can be directly used after adding water. At present, the batching machine connects the signal and the digital signal for opening and closing the hopper door to the PLC control system. Through the screw conveyor batching machine, the hopper door is opened to start loading materials, and the hopper door is closed after loading is completed. When the control system receives the signal of the screw's arrival, it collects the data of the batching machine and records it as the real-time weight. When it receives the signal of the hopper closing the silo door, it collects the data of the batching machine and records it as the real-time weight. Then, the system calculates the net weight, saves it, displays it and uploads it. When the system receives the spiral arrival signal, it starts the algorithm and stores the collected data in the defined array. When the next cycle period arrives, the collected data is compared with the first value in the array. If the value is within the defined threshold, the insertion sort algorithm is run to store the value in the array. Perform operations in sequence. Each collected value is compared with the first value in the array, and determine whether to save based on the result. If all consecutive values meet the conditions, it indicates that the weight of the object on the batching machine is in a stable state, and thus the flow rate for this time can be obtained. The intermediate value, loop period and array dimension can be adjusted according to actual application.

The material used as the binder in the mixture is found to have the corresponding ash dosage on the standard curve graph based on the solution titration consumption of a certain mass of the sample. Based on the detected ash dosage data, the rotational speed of the screw conveyor (for cement binder) or the belt (for two-ash binder) is repeatedly adjusted to make the ash dosage reach the designed amount. The batching machine takes the weighing instrument as the core to control other equipment to complete the batching. The raw materials are driven by the screw conveyor and fall from the silo into the weighing and batching machine, respectively conveying different materials. The running speed of the screw conveyor is adjusted by the frequency converter according to the output voltage of the weighing instrument. The formula of the ingredients and the batch of ingredients can be set through the keyboard of the weighing instrument. The weighing instrument automatically selects the required silo and sends instructions to drive the screw conveyor motor, causing the materials to fall into the weighing and batching machine. The weighing module on the weighing and batching machine outputs a weighing signal, which is then controlled by the weighing instrument to adjust the speed of the screw conveyor and control the feed volume, so that the end value reaches sufficient accuracy. When the batching is completed, the door opens automatically, and the materials enter the mixer for mixing. The weighing instrument automatically calculates the mixing time. After the mixing is completed, the finished materials are discharged.
