The application provides a material flow meter. The material flow meter comprises a rotating shaft, a detection board, a counterweight, an angular displacement sensor, and a bearing, two sides of the rotating shaft are respectively connected with the detection board and the counterweight, when the rotating shaft is horizontally arranged, the gravity torque of the detection board and the gravity torque of the counterweight are balanced, and the rotating shaft is provided with the bearing used for fixing the rotating shaft and the angular displacement sensor used for detecting the rotation angle of the rotating shaft and sending detection signals. According to the material flow meter, the impulsive force caused by the impact on the detection board by a detected medium and a force generated by downward sliding of the powder material on the detection board are converted to electric signals and inputted to a flow integrating meter, the operation of the flow of the material falling freely is realized based on the theorem of momentum, the instantaneous flow and the accumulative flow are displayed, the opening degree of a discharge valve is controlled via a programmable logic controller, the blanking is stable, and the blanking amount is accurately measured.
Description
technical field [0001] The invention relates to a metering device, in particular to a material flow meter, a powder material flow control system and a control method thereof. Background technique [0002] In the gypsum board production process, it is necessary to uniformly mix and form the plaster powder, starch, additives, etc. in strict proportions. The plaster powder is controlled by the discharge valve at the bottom of the silo and the belt scale. The fluctuation is relatively large, and it is easy to It caused the bucket elevator and the circular pipe conveying reamer to block the material, which seriously affected the continuity of production. With the improvement of the molding speed of the company's new production line, it is required to control the blanking amount of plaster powder more accurately and reduce the fluctuation of blanking. Contents of the invention [0003] This application is aimed at controlling the discharge volume through the discharge valve at ...
