[0042] Working principle:

[0043] First, place the corrugated cardboard on the cutting base 1. During cutting, the driving motor 401 on the cutting component 4 can be turned on to drive the rotating cam 402 to rotate, so that the rotating cam 402 rotates and presses the cutting knife 405 below, causing the cutting knife 405 to enter the cutting groove 10 on the upper surface of the cutting base 1, facilitating the cutting work of the corrugated cardboard. When the convex part of the rotating cam 402 moves away from the cutting knife 405, the cutting knife 405 is reset under the reset action of the first spring 406, facilitating the cutting work of the corrugated cardboard;

[0044] Before cutting, the adjusting gear 607 on the centering component 6 can be rotated, so that the adjusting gear 607 drives the winding wheel 602 to rotate and wind the connecting rope 603 through the rotating shaft 601, so that the connecting rope 603 pulls the movable plate 604, causing the movable plate 604 to slide on the side of the cutting base 1 and the upper surface of the side plate 5, and then facilitating the extrusion plate 606 at the end of the movable plate 604 to centrally extrude the corrugated cardboard, avoiding the problem of the corrugated cardboard skewing during transportation;

[0045] After the adjusting gear 607 rotates, then rotate the adjusting screw 802 on the positioning assembly 8, so that the adjusting screw 802 performs a threaded movement with the fixing plate 801. Further, it is convenient for the adjusting screw 802 to drive the limiting tooth block 804 to move upward through the limiting plate 803, so that the limiting tooth block 804 can be engaged into the adjusting gear 607, facilitating the positioning after the rotating shaft 601 rotates;

[0046] The limiting wheels 905 on the cardboard limiting assembly 9 provided at both ends of the fixed frame 2 can, through the use of the third spring 906 between the connecting rod 904 and the fixed cylinder 903, facilitate the extrusion and limitation of the corrugated cardboard transmitted below, improving the stability of corrugated cardboard cutting.

[0047] This corrugated cardboard cutting device of the present utility model can, through the use of the centering assembly in the inner cavity of the cutting seat, center and limit the corrugated cardboard through the pressing plates at the upper ends of the movable plates at both ends above the cutting seat, avoiding the problem of skew when the corrugated cardboard is conveyed. At the same time, in cooperation with the use of the positioning assembly, the meshing between the limiting tooth block on the upper surface of the limiting plate and the adjusting gear is facilitated, so as to position after the rotating shaft rotates;

[0048] This corrugated cardboard cutting device of the present utility model can, through the use of the cardboard limiting assemblies at both ends of the fixed frame, limit and extrude the corrugated cardboard through the limiting wheels below the connecting rod under the action of the third spring during cardboard conveying, improving the stability of corrugated cardboard cutting.

[0049] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
