[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3This utility model provides a technical solution: a cushioning structure for composite cushioning packaging paperboard, comprising a composite cushioning packaging paperboard body 1, a corrugated paperboard layer 8 in the middle of the composite cushioning packaging paperboard body 1, and a first foam layer 7 and a second foam layer 9 respectively bonded to both sides of the corrugated paperboard layer 8. The first foam layer 7 and the second foam layer 9 have the same structure, and the opposite sides of the first foam layer 7 and the second foam layer 9 are formed by wire cutting to form an interlocking toothed structure. This structure can enhance the impact resistance of the composite cushioning packaging paperboard body 1 through the cushioning properties of the first foam layer 7 and the second foam layer 9 themselves. Furthermore, the other side of the first foam layer 7 and the second foam layer 9 are respectively provided with a first connecting paperboard 6 and a second connecting paperboard 10. The toothed structures of layer 7 and the second foam layer 9 are respectively engaged in the grooves above and below the corrugated cardboard layer 8, and the toothed structures of the first foam layer 7 and the second foam layer 9 are smaller than the size of the grooves above and below the corrugated cardboard layer 8. This structure, by engaging with the corrugated cardboard layer 8, can reduce the overall thickness of the composite cushioning packaging cardboard body 1 and ensure that there is space for mutual movement between the first foam layer 7 and the second foam layer 9, allowing the first foam layer 7 and the second foam layer 9 to work with the corrugated cardboard layer 8 for cushioning and shock absorption. The other side of the first connecting cardboard 6 and the second connecting cardboard 10 are respectively bonded with the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11, and the corrugation direction of the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11 is the same. Furthermore, the corrugated directions of the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11 are perpendicular to the corrugated cardboard layer 8. The first corrugated cardboard layer 5 and the second corrugated cardboard layer 11 are symmetrically arranged, and the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11 have the same structure as the corrugated cardboard layer 8. This structure, through the corrugated cardboard layer 8 which is perpendicular to the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11, can provide better compressive strength, avoiding deformation or collapse when pressure is applied along the corrugated direction, thereby avoiding affecting the cushioning effect. The other side of the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11 are respectively provided with a first waterproof partition 4 and a second waterproof partition 12, and the other side of the first waterproof partition 4 and the second waterproof partition 12 are bonded with a first bubble wrap layer. 3. The first bubble film layer 3 and the second bubble film layer 13 have the same thickness, and both the thickness of the first bubble film layer 3 and the second bubble film layer 13 is greater than the thickness of the first panel 2. This structure, with the first bubble film layer 3 and the second bubble film layer 13 being existing bubble film structures, has a cushioning effect. By placing the first bubble film layer 3 and the second bubble film layer 13 in the area near the outer side, it can initially resist internal and external impact forces, achieving a highly efficient cushioning effect. Furthermore, the other side of the first bubble film layer 3 and the second bubble film layer 13 is provided with the first panel 2 and the second panel 14. The first panel 2, the first waterproof partition 4, the first connecting cardboard 6, the second connecting cardboard 10, the second waterproof partition 12, and the second panel 14 have the same thickness.Furthermore, both sides of the first panel 2, the first waterproof partition 4, the first connecting cardboard 6, the second connecting cardboard 10, the second waterproof partition 12, and the second panel 14 are covered with a waterproof membrane structure. This structure allows the first panel 2, the first waterproof partition 4, the first connecting cardboard 6, the second connecting cardboard 10, the second waterproof partition 12, and the second panel 14 to form a multi-layer structure, ensuring the overall structural strength of the composite cushioning packaging cardboard body 1 and acting as a separator for the cushioning structure. Simultaneously, it achieves functional zoning, allowing the composite cushioning packaging cardboard body 1 to avoid moisture damage and maintain its cushioning effect through highly efficient waterproofing.
[0018] Working Principle: When using the cushioning structure of this composite cushioning packaging cardboard, firstly, when the main body 1 of the composite cushioning packaging cardboard is subjected to impact, the first bubble wrap layer 3 and the second bubble wrap layer 13 provide cushioning treatment both inside and outside. The first panel 2 and the first waterproof partition 4 fix the first bubble wrap layer 3 on both sides, allowing the first panel 2 and the first waterproof partition 4 to move relative to each other, thus cushioning and absorbing shock for the first bubble wrap layer 3. The second panel 14 and the second waterproof partition 12 fix the second bubble wrap layer 13 on both sides. When the second panel 14 and the second waterproof partition 12 move relative to each other, the second bubble wrap layer 13 provides shock absorption. The first bubble wrap layer 3 and the second bubble wrap layer 13 provide initial shock absorption, and then the impact force is transmitted to the first... The corrugated cardboard layer 5 and the second corrugated cardboard layer 11 are further cushioned. The corrugated cardboard layer 8, being perpendicular to the first corrugated cardboard layer 5 and the second corrugated cardboard layer 11, makes the overall strength of the composite cushioning packaging cardboard body 1 higher and less prone to damage to the cushioning structure. The first foam layer 7 and the second foam layer 9 are further reinforced with the corrugated cardboard layer 8 through a toothed structure, improving the cushioning performance of the composite cushioning packaging cardboard body 1 while ensuring its strength. The first connecting cardboard 6 connects the first corrugated cardboard layer 5 and the first foam layer 7, and the second connecting cardboard 10 connects the second corrugated cardboard layer 11 and the second foam layer 9, ensuring the stability of each layer structure and thus completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
