Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of particle packaging scales, in particular to a double-bucket particle packaging scale. Background Art
[0002] A dual-hopper granule packaging scale is a crucial piece of equipment used in the chemical, food, and pharmaceutical industries for accurately measuring and packaging granular materials. Common dual-hopper granule packaging scale designs often utilize two storage hoppers to improve packaging efficiency.
[0003] Currently, in existing dual-hopper granule packaging scales, when granular materials are conveyed to the measuring hopper, due to the close contact and interaction between the particles, the materials tend to form a dense accumulation layer at the bottom of the measuring hopper. This accumulation not only restricts the free flow of the materials, but also may cause uneven distribution of the materials inside the measuring hopper, thereby affecting the smoothness of the materials falling. As the accumulation phenomenon intensifies, the rate of material falling will gradually slow down, or even be completely blocked, resulting in a significant deviation between the expected measured weight and the actual amount of falling materials. Therefore, the utility model provides a dual-hopper granule packaging scale. Utility Model Content
