The support frame 1 is a basic support structure and comprises a front hanging beam 12, a horizontal frame 11, supporting legs, balancing rods, connecting rods and the like, as shown in fig. 1 and 2. The supporting legs, the balance bar and the connecting bar are all the prior art which can be easily thought by a person skilled in the art, and therefore, the detailed description is omitted here.

The horizontal frame 11 is provided with the displacement device 2, and the displacement device 2 comprises a three-axis three-dimensional moving structure, so that position regulation and control in a three-dimensional space can be realized. Laser cutting machine 3 is connected with displacement device 2's displacement output for displacement device 2 can regulate and control laser cutting machine 3's position, carries out the accurate cutting to the thin slice 9 in the cutting region on the edge-to-edge cutting platform 4, and the control cuts off-the-shelf shape.

The roll gap of the roller device 8 is arranged right opposite to the cutting area, and the height of the roll gap is not lower than the height of the platform where the cutting area is located, so that the sheets 9 in the roll gap can be smoothly conveyed and placed on the platform where the cutting area is located.

When the height of the roll nip is the same as the height of the platform on which the cutting zone is located, i.e. flush, the sheet 9 can be placed just directly above the platform on which the cutting zone is located. There is almost no angle between the sheet 9 and the platform where the cutting area is located, and the cutting shape of the laser cutter 3 is completely determined by the laser track of the laser cutter 3.

The diameter of the lower roller 81 may be smaller than that of the upper roller 82, and one of the rollers is used as an active roller, and the rotation direction is adjusted to convey the sheet 9 in a specific direction.

For the second rod 44, when the sheet 9 is conveyed in the horizontal direction through the rolling gap between the lower roller 81 and the upper roller 82, the height of the rolling gap should not be lower than the height of the second rod 44, and the height difference is small, so that the sheet 9 cannot be conveyed into the cutting area, and on one hand, the phenomena of abutting, breaking, damage and the like with the side wall of the second rod 44 can be avoided; on the other hand, the included angle between the sheet 9 and the platform where the cutting area is located can be reduced, and accurate shape control cutting is realized.
