Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and more specifically, it relates to a honeycomb corrugated composite paperboard. Background Technology

[0002] Honeycomb panels are made based on the principle of honeycomb structure in nature. Corrugated paper is bonded together to form countless hollow three-dimensional regular hexagons to form the core, and then face paper is glued to both sides. It is a new type of sandwich structure environmentally friendly and energy-saving material.

[0003] Corrugated cardboard consists of a flat linerboard (face paper), a corrugated linerboard (corrugated paper) in the middle, and an inner backing paper. The face paper protects and enhances the appearance of the product, the corrugated paper is the core, providing strength and support, and the backing paper increases stability and protects the product.

[0004] The former has strong resistance to end-face impact and small deformation; the latter has strong resistance to side impact and small deformation. Therefore, honeycomb panels are difficult to bend, while corrugated cardboard is easy to bend, which limits its use in certain applications and results in poor overall performance. Accordingly, this utility model proposes a honeycomb corrugated composite cardboard. Utility Model Content

The honeycomb holes on the honeycomb paperboards are vertically connected. A corrugated core board is provided between two adjacent honeycomb paperboards. The upper ends of the corrugated core board and the honeycomb paperboard are bonded to the top paper, and the lower ends are bonded to the bottom paper.

[0007] The present invention is further configured such that: a first slit and a second slit are provided between two adjacent honeycomb paperboards, which penetrate the bottom paper and the top paper vertically. The first slit extends from left to right, and the second slit extends from right to left. The first slit and the second slit are arranged alternately.

[0008] The present invention is further configured such that: the corrugated core board includes a middle layer paper, the upper end of the middle layer paper is provided with upper corrugated paper and the lower end is provided with lower corrugated paper, the upper end of the upper corrugated paper is bonded to the face paper and the lower end is bonded to the middle layer paper, and the lower end of the lower corrugated paper is bonded to the bottom paper and the upper end is bonded to the middle layer paper.

[0009] The present invention is further configured such that each of the corrugated core boards is bonded to two adjacent honeycomb cardboard sheets.

[0010] The present invention is further configured such that the spacing between two adjacent honeycomb paperboards is equal.

[0011] The present invention is further configured such that the basis weight of the base paper and the face paper are equal.

[0012] In summary, the present invention has the following beneficial effects: the honeycomb corrugated composite paperboard involved in the present invention achieves the effect of being bendable in specific positions and impact resistant in other positions by using the built-in corrugated core board for bending and the honeycomb paperboard parts on both sides of the corrugated core board for end face impact resistance.

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1 See Figure 1 and Figure 2 As shown, the honeycomb corrugated composite paperboard involved in this embodiment includes a bottom paper 1 arranged at the bottom and a top paper 2 arranged at the top. A plurality of honeycomb paperboards 3 are arranged at intervals along the length direction between the top paper 2 and the bottom paper 1. The honeycomb holes on the honeycomb paperboards 3 are vertically connected. A corrugated core board 4 is provided between two adjacent honeycomb paperboards 3. The upper ends of the corrugated core board 4 and the honeycomb paperboards 3 are bonded to the top paper 2, and the lower ends are bonded to the bottom paper 1.

[0017] Furthermore, the corrugated core board 4 includes a middle layer paper 41, with an upper corrugated paper 42 at the upper end and a lower corrugated paper 43 at the lower end. The upper end of the upper corrugated paper 42 is bonded to the face paper 2, and the lower end is bonded to the middle layer paper 41. The lower end of the lower corrugated paper 43 is bonded to the bottom paper 1, and the upper end is bonded to the middle layer paper 41.

[0018] Furthermore, each of the corrugated core boards 4 is bonded to two adjacent honeycomb paperboards 3.

[0019] Furthermore, the spacing between two adjacent honeycomb paperboards 3 is equal.

[0020] Furthermore, the base paper 1 and the face paper 2 have the same weight.

[0021] In this embodiment, by connecting and arranging a corrugated core board 4 between two honeycomb paperboards 3, the composite paperboard at the position of the corrugated core board 4 is given the function of free bending, while the composite paperboard at the other positions of the honeycomb paperboards 3 still has the end face resistance to compression and impact.

[0022] Example 2 See Figure 1 and Figure 2 As shown, the honeycomb corrugated composite paperboard involved in this embodiment is further configured based on embodiment 1, with a first slit 5 and a second slit 6 extending vertically through the bottom paper 1 and the face paper 2 between two adjacent honeycomb paperboards 3. The first slit 5 extends from left to right, and the second slit 6 extends from right to left, with the first slit 5 and the second slit 6 arranged alternately.

[0023] In this embodiment, the staggered arrangement of the first slit 5 and the second slit 6 makes it easier and more convenient to bend the composite paperboard at the position of the corrugated core board 4.

[0024] The honeycomb corrugated composite paperboard involved in this utility model achieves the effect of being bendable in specific positions and impact-resistant in other positions by using the built-in corrugated core board for bending and the honeycomb paperboard on both sides of the corrugated core board for end face impact resistance. It has complete overall functions and strong practicality.
