The lifting loading terminal is driven to move upwards through the row lifting driving mechanism, and moves transversely to be close to the unreeling mechanism of the corresponding laser cutting machine, so that the inner hole of the stainless steel coiled material is aligned with the unreeling shaft 15 of the unreeling mechanism, and then the stainless steel coiled material is pushed onto the unreeling shaft 15 through the transverse movement.
The two centering clamping plates 3 are driven by the centering driving motor 5 to be far away from the stainless steel coiled material, the two lifting claws 1 are driven by the opening and closing driving mechanism to be opened, and the lifting loading terminal is driven by the row lifting driving mechanism to reset, so that loading work is completed.
The foregoing is illustrative of the present invention, and is not to be construed as limiting thereof, but rather as various changes, modifications, substitutions, combinations, and simplifications which may be made without departing from the spirit and principles of the invention are intended to be included within the scope of the invention.
