The application discloses a longitudinal shearing and slitting device for precise stainless steel cold-rolled thin strips and relates to the field of stainless steel cold-rolled thin strip
processing. The device comprises a base, an unwinding roller, a flattening mechanism, a
cutting mechanism and a winding roller. The unwinding roller, the flattening mechanism, the
cutting mechanism and the winding roller are installed on the base, and the flattening mechanism is provided with two groups. A separating mechanism is installed on the left side of the
cutting mechanism, and the separating mechanism is connected with a
polishing mechanism. The longitudinal shearing and slitting device for precise stainless steel cold-rolled thin strips adopts two groups of reciprocating
polishing mechanisms, can polish the cutting edges of the stainless steel strips for multiple times after the stainless steel strips are slit, effectively guarantees the deburring effect of the cutting edges of the stainless steel strips, cooperates with a self-cleaning mechanism, can move the two
polishing plates to the limit positions, automatically cleans the surface debris of one polishing plate, effectively avoids the adhesion of the debris and impurities and influences the polishing effect of the polishing plate on the stainless steel strips, and guarantees the polishing quality.
