Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 5, the paper cutting knife provided in this embodiment includes a knife roll 1, blades 2 are convexly disposed on an outer circumferential surface of the knife roll 1 along an axial direction thereof, and a plurality of notches 21 are uniformly spaced on the blades 2. The depth of the notch 21 extends from the blade part of the blade 2 to the outer circumferential surface of the knife roller 1, and is larger than the thickness of the paper to be cut, so that the paper can be completely cut through in the thickness direction.

It should be noted that the arrangement structure of the blades 2 is adapted to the shape and size of the paper to be cut, wherein, as shown in fig. 2, when the blades 2 are in a linear arrangement structure and are arranged parallel to the axis of the knife roller 1, the blades can also be used for cutting paper with higher strength, so that the cut paper is continuously conveyed, the positioning and conveying precision of the paper is improved, and the cutting quality is further improved.

As shown in fig. 3, when the blades 2 are in the form of a special-shaped arrangement structure and are arranged in a folding line, the method is mostly applied to the production of special-shaped box boards.

In addition, as shown in fig. 1, 4 and 5, a plurality of elastic pressing blocks 3 are uniformly distributed on one side of the blade 2 along the axial direction of the knife roll 1, and the distances from the elastic pressing blocks 3 to the blade 2 are equal.

As another embodiment, a plurality of elastic pressing blocks 3 are respectively and uniformly distributed on both sides of the blade 2 along the axial direction of the knife roll 1, and the distances from the elastic pressing blocks 3 to the blade 2 are respectively equal.

Make blade 2 cut this elastic pressing block 3 before to the cardboard play and compress tightly the positioning action through setting up elastic pressing block 3, and utilize its elastic action, and then make blade 2 can be quick, the orderly cardboard of cutting of tangent plane, improve the cardboard greatly and cut the quality.

Example two

As shown in fig. 6 to 8, in which the same or corresponding components as in the first embodiment are denoted by the same reference numerals as in the first embodiment, only the points of difference from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that: as shown in fig. 6, the utility model also provides a paperboard cutting device, which comprises a facial tissue conveying part I, a corrugated paper conveying part II and a compound mechanism III for automatically laminating the facial tissue and the corrugated paper; the paper board cutting mechanism 4 is arranged on the rear side of the compound mechanism iii, the paper board cutting mechanism 4 comprises a transmission roller 41 and a paper cutting knife above the transmission roller 41, a paper board transmission channel 42 is formed between the transmission roller 41 and the paper cutting knife, as shown in fig. 7 and 8, the paper board 300 formed by compound formation of the compound mechanism iii is transversely cut at intervals by the paper cutting knife through the paper board transmission channel 42, and therefore continuous transmission between adjacent paper boards 300 is achieved.

In this embodiment, the cardboard cuts mechanism 4 and sets up behind compound mechanism III, and to the cardboard that intensity is not high, this mode of setting has avoided coiling on rotor 1 because of the cardboard tip that the glue problem leads to cutting, realizes cardboard sola continuous output through subsequent transport mechanism, is particularly applied to the production of special-shaped case cardboard.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
