Lithium strip extrusion structure with cleaning medium output function

Abstract

The invention relates to the field of lithium strip production equipment, in particular to a lithium strip extrusion structure with a cleaning medium output function. The lithium strip extrusion structure comprises a pipe body. The pipe body comprises an extrusion section and a matching section. A first channel formed by the inner wall of the extrusion section is used for extruding metal lithium.The inner wall of the matching section is an inner thread and used for being connected with a mold in a threaded manner. Lithium chloride output holes capable of being opened or closed are correspondingly formed in the inner wall of the extrusion section and the inner wall of the matching section. Lithium chloride powder can be output into the extrusion section and the matching section when the lithium chloride output holes are opened. The invention aims at providing the lithium strip extrusion structure capable of conveniently cleaning metal lithium remained in the lithium strip extrusion structure.

Description

technical field [0001] The invention relates to the field of lithium strip production equipment, in particular to a lithium strip extrusion structure with a cleaning medium output function. Background technique [0002] Lithium is more and more widely used in our life, and the demand is increasing. Among them, the demand for use in the battery field is increasing. [0003] Among the upstream manufacturers of lithium battery manufacturers, lithium raw materials need to be extruded into ribbon-shaped lithium ribbons, and then the lithium ribbons are rolled up to form discs, which are then packaged and supplied to downstream manufacturers. [0004] The process of manufacturing lithium strips is to place metal lithium in a pipe. The head end of the pipe is provided with a mold with strip-shaped openings, and then the pressure rod is pushed from the tail end of the pipe, and the metal lithium is in the pipe. Pushed, it moves to contact the die and squeezes out from the opening o...

Problems solved by technology

[0008] At the same time, since there will inevitably be a gap between the mold and the mating section, and the mating section is under great pressure during the extrusion process, after a period of time in the lithium strip extrusion process, a small amount of metal will be squeezed into the inner wall of the mating section. If lithium remains in it, it will also form a plaque-like structure, which will stick to the inner wall of the mating section (on the internal thread). After accumulating to a certain extent, it will cause adverse effects on the next and subsequent mold installations. Therefore, production After a period of time, it is also necessary to stop work to remove these plaques

[0009] The current methods for cleaning the plaques are manual stripping or wiping, both of which are very inefficient and prone to residual lithium metal. The stripping method is also easy to damage the inner wall of the pipeline. At the same time, it cannot be cleaned with water, because after cleaning It needs to dry the pipeline, which will affect the operation of the production line, and the unqualified water drying will cause the scrapping of large quantities of products
