[0003] However, there are still some outstanding problems in the actual application process. For example, during the metering process, the uneven distribution of powder can easily cause the agglomeration of powder, which will not only interfere with the normal metering process, but also affect the quality accuracy of the final metering. In addition, in the feeding channel after the metering is completed, powder accumulation and blockage often occur, which causes a large error in the final metering result and affects the accuracy and stability of the feeding. The above problems seriously restrict the further improvement of the accuracy and reliability of the existing metering devices, resulting in adverse consequences such as inaccurate metering and unsmooth feeding in actual operation, which brings many inconveniences and losses to related production and applications.
