Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, in particular to a metal belt slitting equipment with a static electricity removal function. Background Art

[0002] The existing slitting machines for slitting metal strips generally lay a layer of blanket at the position of the slitting mechanism to protect the bottom of the metal strip when slitting the metal strip, and use the blanket to buffer the cutting knife during cutting to extend the service life of the cutting knife.
