The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 4, a first slitting tool 1, a second slitting tool 2 and a third slitting tool 3 are arranged along the feeding direction of a paper core 4, the second slitting tool 2 comprises a square frame 2-1, the square frame 2-1 is obliquely arranged, two sides of the square frame 2-1 are respectively provided with a vertical second slitting groove 2-2, and the upper end of the second slitting groove 2-2 is provided with a second cutter 2-3.

The inclination angle of the square frame 2-1 is 60 °.

The second cutters 2-3 on the two sides of the square frame 2-1 are symmetrically distributed relative to the geometric center of the square frame 2-1, so that the paper core 4 can be divided into regular dodecagons after being cut by a second dividing tool.

The second dividing grooves 2-2 on both sides of the square frame 2-1 are arranged in parallel, so that two corners of the paper core 4 can be cut off conveniently.

The bottom of the square frame 2-1 is provided with a second bottom plate 2-4.

The first slitting tool 1 comprises a rectangular frame 1-1, a vertical first slitting groove 1-2 is formed in the rectangular frame 1-1, and a first cutter 1-3 is arranged at the upper end of the first slitting groove 1-2.

The third slitting tool 3 comprises a U-shaped frame 3-1, a third cutter 3-2 is arranged on one side of an opening of the U-shaped frame 3-1, a flange 3-3 is arranged on one side of the third cutter 3-2, and the flange 3-3 facilitates the third cutter 3-2 to slit the paper core 4.

The bottom of the U-shaped frame 3-1 and the flange 3-3 are provided with a third bottom plate 3-4.

When the cutting tool is specifically used, the lower ends of the first cutting tool 1, the second cutting tool 2 and the third cutting tool 3 can be positioned on the same horizontal line, so that the operation is convenient.

Before the operation of the utility model, a corresponding number of cutters are configured in the 3 slitting tools, and the relative positions between the cutters and the tools are adjusted to ensure that the size of the paper core after being slit meets the requirement.
