[0033] During use, the present invention places a metal sheet onto the adjustable blanking assembly 3 and holds it in place, with the held area being the non-cutting zone. The cutting assembly 2 then cuts the metal sheet into the desired shape. After cutting, the adjustable blanking assembly 3 transports the scrap metal sheet to the front end, where it is unloaded using the gaps in the adjustable blanking assembly 3. To completely remove the cut metal material, the vibrating blanking assembly 4 vibrates the material during transport, causing it to fall through the gaps in the adjustable blanking assembly 3 onto the chain conveyor 5, which then transports it to a collection area.

[0034] The cutting assembly 2 includes a laser cutter 21 and a linear module 22. Two sets of linear modules 22 are symmetrically fixed to the left and right sides of the top of the mounting base 1. The left and right sides of the bottom of the laser cutter 21 are fixedly connected to the slider ends of the two sets of linear modules 22. The cutting end of the laser cutter 21 can move left and right. By moving the laser cutter 21 back and forth on the linear modules 22, it is convenient to cut metal sheets.

[0035] The adjustment assembly 31 includes a pitch-changing module 311 and support racks 312. Two sets of pitch-changing modules 311 are symmetrically mounted on the left and right side walls inside the mounting base 1.

The rear end bottom of the lower pressure arm 325 is fixedly connected to a fitting block 327. The mounting bracket is connected to the slider at the front end of the pitch variable module 311.

[0037] When the present invention is in use, a metal sheet is placed on the support rack 312, and the output end of the driving cylinder 322 is extended to drive the lower pressure arm 325, so that the lower pressure arm 325 drives the bonding block 327 to press down to fix the metal sheet, and the area where the bonding block 327 presses is the non-cutting area of ​​the metal sheet; then the laser cutting machine 21 cuts the metal sheet into the required shape; after the cutting is completed, the sliding end of the variable pitch module 311 drives the support rack 312 and the mounting bracket 321 to move, because the bonding block 327 and the frontmost support rack 312 fix the metal sheet; the cut metal sheet waste can be transported to the front end along with the mounting bracket 321, and the metal sheet waste is removed manually. During the transportation process, the support rack 312 is driven by the variable pitch module 311, so that the gaps between the multiple groups of support racks 312 are continuously increased, so that the metal cutting material can be discharged through the gaps.

[0039] The mounting plate 46 is an L-shaped structure, and the two inner side surfaces of the mounting plate 46 are fixedly connected to the bottom surface and the outer side surface of the pitch variable module 311 respectively.

[0040] When the present invention is in use, the metal sheet waste is transported to the front end for unloading along with the mounting frame 321, and the driving motor 41 drives the turntable 43, and the turntable 43 drives the slide bar 45 to slide up and down in the mounting shell 42 through the second connecting rod 44, and the slide bar 45 drives the mounting plate 46 to move up and down, and the mounting plate 46 drives the variable pitch module 311 to vibrate up and down, so that the metal sheet will vibrate during transportation, so that the metal sheet cutting material will fall off completely, and fall from the increasing gap between the supporting racks 312 onto the chain conveyor 5, and the chain conveyor 5 will transport the metal cutting material to the collection area.
