[0003] When batch production materials are needed, various ingredients of raw materials need to be mixed, but the proportions of each raw material added are inconsistent. Since the speed of the material conveying device is fixed and the distribution of the materials on the conveying device is uneven, manual control of the amount of raw materials is needed when adding raw materials, which not only reduces work efficiency, but also may cause human error and inaccurate control of the amount.

The target raw material is first selected and a preset weight value is set. The transmission starting point is first selected according to the discharging point. Then, the position of the endpoint of the conveying device is obtained according to the preset weight value, so as to obtain the conveying distance. According to the proportion of the target raw material, the preset weight values of other raw materials are obtained through formula conversion, so as to obtain the conveying distances of different conveying devices.
