| description | The invention relates to a material continuous metering and distribution method. The method includes the following steps that: a) a material metering device is started; b) a material feeding device and a metering screw are started, so that material distribution is realized; c) the flow F of the current output material of the metering screw is calculated according to a formula F=A*P; d) the sum Qm of the material conveyed by the metering screw after the metering screw operates for t seconds is calculated; e) the correction value of the flow calibration coefficient of a weighing sensor II is calculated; f) the correction value P' of the flow calibration coefficient is adopted to correct an original flow calibration coefficient P in the step c); and g) the step b) to step f) are repeated. In a whole metering control process, the difference of calculated flow and set flow is applied; the actual material can be distributed according to the set flow through controlling the speed of the metering screw 6, and therefo |
