Lithium strip calendering and shearing mechanism

The invention discloses a lithium strip calendering and shearing mechanism which comprises a calendering device. The calendering device comprises a first calendering roller and a second calendering roller which are arranged in parallel, and the outer surface of the first calendering roller is provided with a plurality of profiling grooves which are distributed at intervals and are used for shearing a lithium strip. The lithium strip, a first isolating membrane and a second isolating membrane simultaneously enter the space between the first calendering roller and the second calendering roller, the lithium strip is matched with the profiling groove under the extrusion of the first calendering roller and the second calendering roller, and the section, entering the profiling groove, of the lithium strip is calendered into a lithium membrane, then the lithium membrane is sheared into a lithium membrane section, and the lithium membrane section is attached to the first isolating membrane; and the second isolating m
