During manufacturing, it usually requires a certain ratio of metal powder to be mixed in advance, so a metal powder mixing device is often needed;

[0003] For example, the patent with publication number CN220574739U discloses a powder mixing device for laser additive manufacturing. Specifically, the powder to be mixed is proportioned by a proportioning component, so that alloy powders of different components can be prepared. At the same time, the material contained in the receiving chamber is stirred by a stirring member in the storage component, so that the material can be prevented from agglomerating and agglomerating, thereby improving the mixing rate of the material. Among them, the proportioning component adopts a weighing device, which can directly receive the material discharged by the storage component and weigh the material.

[0004] However, although a stirring member is used to break up the lumps of materials in the storage device, when discharging the materials, the first electric first telescopic rod is used to control the cover plate to release the materials from the storage device, and the loading bucket provided with a weighing device receives various materials. This is not only inconvenient to control the materials released, but also lacks a structure to evenly mix the materials after weighing.

[0005] Based on the above description, there is an urgent need for an additive manufacturing metal powder mixing device that is easy to control the ingredient ratio. Utility Model Content
