Problems solved by technology

For example, the Chinese patents with application numbers 200710142591.6, 201010108011.3 and 201310178558.4 all measure the falling materials through the calculation of the weight reduction of the weighing bin. Although these schemes do not need to consider the amount of air, they do not consider the weight loss of materials when they fall from the feeding valve. The effect affects the accuracy of weighing and measurement, and cannot meet the requirements of high-precision blanking, and these solutions can only be used for continuous blanking and cannot be directly applied to batch blanking

Abstract

The invention discloses a screw rod weightless type material discharging machine based on a neural network and a controller of the screw rod weightless type material discharging machine. The materialdischarging machine comprises a rack, a discharging bin, a spiral conveyor, a material mixing hopper, a weighing module, a material falling valve and the controller. The controller adopts a neural network module and predicts the weightless value of a material based on a material level, a material falling rate and the material density of the discharging bin and the spiral blade diameter, the screwpitch and the maximum rotating speed of a screw rod of the spiral conveyor, so that the closing time of the spiral conveyor is adjusted. According to the screw rod weightless type material dischargingmachine based on the neural network and the controller of the screw rod weightless type material discharging machine, modeling is conducted on discharging weighing by adopting the neural network, theweightless value of the falling material under different material falling states can be accurately predicted through the trained network so that direct and accurate discharging can be achieved, and the screw rod weightless type material discharging machine is suitable for small batch production; a bin position sensor and a vibrating rod are used for detecting and adjusting the material accumulative form in the discharging bin, and fluctuation of the material falling rate is reduced; and the total error of batch discharging is reduced by controlling the discharging accumulative error, and thedischarging efficiency is improved due to the fact that the screw rod can maintain the high running speed.
