It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, the transverse ring-crush reinforced recycled paper according to the embodiment of the present invention comprises a first paper board 1, a second paper board 2, a bottom board 3, a first paper core layer 4, a second paper core layer 5 and a third paper core layer 6, the paper core layer I4 is arranged between the paper board I1 and the paper board II 2, the paper core layer II 5 is arranged on one side edge of the paper board II 2 far away from the paper core layer I4, the bottom plate 3 is arranged below the paper core layer II 5, the paper core layer III 6 is arranged between the paper core layer II 5 and the bottom plate 3, a plurality of arc-shaped grooves I7 are arranged in the paper core layer I4, an arc-shaped groove II 8 is arranged between the adjacent arc-shaped grooves I7, a plurality of honeycomb holes 9 are arranged in the paper core layer II 5, and the part between adjacent honeycomb holes 9 is provided with a cylinder structure 10 at intervals from top to bottom, and a corrugated board 11 is arranged in the paper core layer III 6.

By means of the technical scheme, the plurality of paper core layers are added among the paper boards, and the arc-shaped grooves and the honeycomb holes 9 are added among the adjacent paper core layers, so that the transverse ring crush performance of the paper boards can be further improved.

As shown in fig. 1, the inside of the cylindrical structure 10 is a hollow structure, and the cylindrical structure 10 can play a supporting role, so that the safety of the honeycomb holes 9 is further ensured, and meanwhile, the hollow structure can reduce the weight of the paperboard.

As shown in fig. 1, a plurality of support columns 12 are arranged between the second paper core layer 5 and the third paper core layer 6, and wave plates are arranged in the support columns 12; the connection between the second paper core layer 5 and the third paper core layer 6 can be further strengthened through the support columns 12, and the pressure resistance of the paperboard can be further strengthened.

As shown in fig. 1, the diameter of the arc-shaped groove two 8 is smaller than that of the arc-shaped groove one 7, and the top ends of the arc-shaped groove one 7 and the arc-shaped groove two 8 are tangent to the bottom end of the paper board one 1; the pressure resistance of the paper core layer I4 can be improved by arranging the arc-shaped grooves II 8 with the diameter smaller than that of the arc-shaped grooves I7 between the arc-shaped grooves I7, so that the transverse ring pressure of the paper board is improved.

As shown in fig. 1, the corrugated board 11 is formed by vertically staggering W-like structures, and the ring pressing of the cardboard can be enhanced from the upper direction and the lower direction respectively through the vertically staggered W-like structures.

In summary, with the aid of the technical solution of the present invention, the compression resistance of the paper board can be increased by disposing the paper core layer one 4 between the paper board one 1 and the paper board two 2, and the annular compression resistance of the paper board can be further increased by the paper core layer two 5 and the paper core layer three 6, which is more beneficial to the use and safety of the paper board, and the arc-shaped groove one 7 inside the paper core layer one 4 can support and buffer the paper board one 1 and the paper board two 2, the arc-shaped groove two 8 can not only strengthen the connection between the arc-shaped grooves one 7, but also further play a role of ring crush between the paper board one 1 and the paper board two 2, the honeycomb holes 9 and the cylinder structures 10 inside the paper core layer two 5 can further strengthen the transverse ring crush of the paper board, the W-like structure staggered inside the paper core layer three 6 can play a role of ring crush strengthening from top to bottom more evenly, the ring crush performance of the structural paperboard is greatly improved.
