AUTOMATIC POWDER SAMPLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/021230
Kind Code:
A1
Abstract:
An automatic powder sampling device, comprising: a material bin (100), the outer side wall of the material bin (100) being provided with a mounting position; a protective cover (200), the protective cover (200) passing through the mounting position and being mounted on the material bin (100), and the side of the protective cover (200) away from the material bin (100) being provided with a discharge port (210); and a sampling assembly, comprising a material scraping rod (300), a material pushing device, a sampling wheel (320) and a cam (330), the cam (330) being fixed in the protective cover (200) in the axial direction of the sampling wheel (320), the sampling wheel (320) being rotatably mounted in the protective cover (200) around the central axis of the cam (330), the outer side wall of the sampling wheel (320) being attached to the inner side wall of the protective cover (200), a recess (322) for placing materials being provided in the outer side wall of the sampling wheel (320), the material scraping rod (300) and the material pushing device passing through the recess (322) and being slidably connected into the sampling wheel (320) in the radial direction thereof, the bottoms of the material scraping rod (300) and the material pushing device abutting against the cam (330) respectively, and the bottoms of the material scraping rod (300) and the material pushing device sliding with respect to the surface of the cam (330) respectively. The device has the characteristics of high automation degree, high automatic sampling efficiency and simple structure, facilitating popularization and use in the field of automatic sampling in production of positive and negative electrode materials of lithium batteries.
