Fixed-size slitting equipment for building curtain wall manufacturing and slitting method thereof

The invention discloses fixed-size slitting equipment for building curtain wall manufacturing and a slitting method thereof, and belongs to the technical field of plate slitting mechanical equipment. The fixed-size slitting equipment comprises a machine base, a first sliding connecting groove is formed in the top of the machine base, and a first sliding connecting base is slidably connected in the first sliding connecting groove. Through mutual cooperation of the designed first sliding connecting base, the first pressing roller, the concave connecting groove, the elastic supporting device, the threaded connecting groove, the circular-truncated-cone-shaped threaded barrel and other structures, the flexibility is high, and glass plates with different widths for the building curtain wall are clamped and fixed, the stability of the glass plate for the building curtain wall on the machine base can be improved, the precision of the hobbing cutter on the surface of the glass plate for the building curtain wall is gu
