Problems solved by technology
Pour directly into the mold cavity at one time, the material is too concentrated, it is not easy to distribute evenly, and it is easy to cause the difference in bulk density when scraping the material
This can only ensure that the material on the surface is scraped flat, but the material on the lower layer cannot guarantee its uniformity due to the bridge phenomenon. The density of the product is uneven, so the strength and hardness vary greatly; some weighing materials are measured by the constant volume method, the dryness and wetness of the materials are different, and whether there is vibration will seriously affect the bulk density, and the constant volume method has a large error

Description
technical field [0001] The invention relates to the field of powder molding, in particular to an automatic weighing feeding and scraping device for powder molding. Background technique [0002] In the powder molding process, it is necessary to weigh a certain weight of powder and put it into a fixed mold for scraping, spreading, and pressing. At present, weighing and scraping by manual operation still accounts for more than 80%. The scraping devices on the market generally use manual weighing, pouring into the cavity of the mold at one time, and then scraping with a scraper. Pour directly into the mold cavity at one time, the material is too concentrated, it is not easy to distribute evenly, and it is easy to cause differences in bulk density when scraping the material. This can only ensure that the material on the surface is scraped flat, but the material on the lower layer cannot guarantee its uniformity due to the bridge phenomenon. The density of the product is uneven,...
