Abstract

The invention discloses a screw-type multi-component material batching method. The controller controls the operation of the screw conveyor and reads the sensing data of the weighing module in real time, respectively performs the calibration of the unloading of each component material, and the unloading of the unloading method. Iteratively predicting the amount in the air; adjusting the speed of the feed pump to control the material level of the lower silo within a small range; and dynamically adjusting the closing time of the screw conveyor based on the comparison between the accumulated feeding amount and the formula data . The materials of each component are discharged in turn, and when the material in the mixing hopper is detected to reach the set value, the material is mixed evenly and then the push plate is opened to discharge the mixture. The invention uses distance sensors, vibrating rods and distributors to reduce the change of material distribution and impact during the feeding process, speed up the iterative prediction convergence speed, obtain a higher feeding speed while ensuring accuracy, and is suitable for small Quick batching of batches.
