Abstract

The invention discloses a screw-type multi-component material batching device and a controller thereof. The batching device includes a frame, multiple sets of lower bins and screw conveyors, a weighing hopper, a weighing module, a blanking valve, a mixing hopper, a control There is an hourglass-shaped distributor on the upper part of the metering hopper, and a distance sensor and a vibrating rod are respectively installed on the side wall of the lower silo and the frame. The controller adjusts the speed of the feeding pump to control the material level of the feeding bin within a narrow range, adjusts the operating speed of the screw conveyor, and performs iterative predictive control of its closing time based on the current and accumulated feeding errors. The invention adopts the distance sensor, the vibrating rod and the distributor to reduce the change of the material distribution and the impact during the feeding process, accelerate the convergence speed of the iterative prediction, obtain a higher feeding speed while ensuring the accuracy, and is suitable for small Quick batching of batches.
