A sliding connection block 18 is arranged inside the sliding installation groove 8, and the sliding connection block 18 is fixedly installed at the bottom of the end of the mounting connecting arm 19 where the rotating limiting arm 21 is installed.

[0033] A bidirectional threaded rod 9 is rotatably installed inside the sliding installation groove 8. The bidirectional threaded rod 9 penetrates through the sliding connection block 18, driving the two sliding connection blocks 18 to approach or move away from each other; both ends of the bidirectional threaded rod 9 penetrate through the sliding installation groove 8 and extend outward, and a control rotating handle is fixedly installed at its extended end.

[0034] Working principle:

[0035] Please refer to Figures 1 to 3 and assemble this device as shown in the figure;

[0036] Taking a large number of rectangular gift packaging box papers as an example, first, according to the chamfering requirements of the gift wrapping paper, determine the positions of the two rotating limiting arms 21. For example, if the chamfer of the rectangular gift packaging box paper is a right triangle with an acute angle of 60 degrees and 30 degrees, then adjust the angle between one of the rotating limiting arms 21 and the corresponding mounting connecting arm 19 to 30 degrees, and adjust the angle between the other rotating limiting arm 21 and the corresponding mounting connecting arm 19 to 60 degrees; then align the chamfer line of the rectangular gift packaging box paper with the chamfering cutter 17 and place it directly below the chamfering cutter 17. Then rotate the bidirectional threaded rod 9 to adjust the distance between the two sliding connection blocks 18 so that the two sides of the rectangular gift packaging box paper that need to be chamfered are respectively in contact with the synchronous baffle 22; after determining the above conditions, place the rectangular gift packaging box papers in batches on the chamfering workbench 1, make the side of the rectangular gift packaging box paper in contact with the synchronous baffle 22, and finally start the telescopic cylinder 5 to make the fixed pressing block 16 press the batch of rectangular gift packaging box papers. Then, the chamfering cutter 17 performs chamfering cutting on the batch of rectangular gift packaging box papers, and the chamfering debris falls into the interior of the bearing box 7 through the chip guide groove 6.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
