[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions. When placing raw materials into a centrifuge, it is usually done manually by pouring the raw materials into the centrifuge for processing, which makes it inconvenient to control the amount of raw materials put in.

[0004] However, the above patent has the following shortcomings: the position of the first feeding pipe needs to be manually adjusted before feeding into the centrifuge, which is not convenient to use; in addition, during the expansion and contraction of the feeding pipe, raw materials are likely to be present in the feeding pipe, which may cause the raw materials to fall during the contraction of the first feeding pipe. Therefore, we propose a centrifuge feeding controller that is convenient for controlling the input amount of raw materials. Utility Model Content
