Description

Technical Field

[0001] The utility model relates to the technical field of graphite mechanical processing, in particular to a feeding device. Background Art

[0002] Graphite negative electrode material is a commonly used negative electrode material for lithium-ion batteries. It is widely used in the field of lithium-ion batteries because of its good electrical conductivity, chemical stability and lithium insertion performance. In the automated feeding production process of graphite negative electrode materials, ton bags filled with graphite negative electrode materials are usually poured into the feed port of the feeding device. Since artificial graphite materials contain magnetic foreign matter such as iron, copper, nickel, and cobalt, these magnetic foreign matter will cause the structure of artificial graphite powder materials to be unstable, affecting important properties of the battery such as the internal resistance, cycle life and capacity performance of the battery. Therefore, magnetic bars are set at the feed port of the feeding device to absorb the magnetic foreign matter in the artificial graphite material. However, since these magnetic bars are fixed on the feeding device, it is inconvenient to clean the magnetic bars after absorbing the magnetic foreign matter. Utility Model Content
