Description

Technical Field

[0001] This utility model relates to the field of paper packaging box and cardboard technology, specifically a composite cushioning combined cardboard structure for paper packaging boxes. Background Technology

[0002] Currently, paper packaging boxes are essential equipment for packaging goods, with huge usage. However, in order to improve the structural strength, load-bearing capacity, and cushioning and impact resistance of paper boxes, these packaging boxes often use multi-layer composite corrugated cardboard. The core layer of the corrugated cardboard is made of corrugated paper or honeycomb paper, which is the core part of the entire cardboard, providing structural strength and cushioning performance. The cross-section of the corrugated paper is generally arranged in a serpentine shape on the inside of the cardboard. In actual application, due to the large gaps between the corrugated paper and the outer and inner layers, it is easy to deform under pressure, resulting in poor overall load-bearing capacity and impact resistance of the cardboard. It is also prone to collapsing due to external force or the squeezing of external objects. Therefore, we propose a composite cushioning combined cardboard structure for paper packaging boxes. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a composite cushioning combined cardboard structure for paper packaging boxes, which solves the problem mentioned in the background art where the gaps between the corrugated paper and the outer and inner layers are large, making it easy to deform under pressure. This results in poor overall load-bearing capacity and impact resistance of the cardboard, making it prone to collapsing due to external forces or the squeezing of external objects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite cushioning combined cardboard structure for paper packaging boxes, comprising:

[0007] Core layer paperboard;

[0008] Two honeycomb paper layers are respectively bonded to the upper and lower surfaces of the core paperboard, and a support mechanism is provided inside the honeycomb paper layers;

[0009] Two connecting cardboard pieces are respectively bonded to two honeycomb paper layers;

[0010] Two corrugated paper layers are respectively bonded to two connecting cardboards, and a second support mechanism is provided on the corrugated paper layers;

[0011] Two outer cardboard layers are respectively bonded to two corrugated paper layers.

[0012] Preferably, the support mechanism includes multiple support paper rings, each of which is bonded to the honeycomb paper layer. The multiple support paper rings are arranged in pairs, and a support paper tube is bonded to each pair of support paper rings. The two ends of the support paper tube are respectively bonded to the core paperboard and the connecting paperboard to improve the load-bearing capacity and impact resistance.

[0013] Furthermore, the second support mechanism includes multiple triangular paper tubes, each of which is bonded to a corrugated paper layer. The multiple triangular paper tubes are respectively bonded to a connecting cardboard and an outer cardboard. Three supporting cardboards are bonded inside each triangular paper tube, and paper pillars are bonded between the three supporting cardboards to improve load-bearing capacity and impact resistance.

[0014] Furthermore, one of the outer cardboard layers is provided with a waterproof layer.

[0015] Furthermore, a wear-resistant layer is provided on the waterproof layer.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a composite cushioning combined cardboard structure for paper packaging boxes, which has the following beneficial effects:

[0018] This paper packaging box uses a composite cushioning modular cardboard structure. Through the combination of core cardboard, honeycomb paper layer, corrugated paper layer, etc., it is easy to assemble into a composite cushioning cardboard. It is easy to cooperate with triangular paper tubes, supporting cardboard, paper columns, etc. to reinforce and support the corrugated paper layer. It is easy to cooperate with supporting paper rings and supporting paper tubes to reinforce and support the honeycomb paper layer. By filling the gaps between the corrugated paper layer and the honeycomb paper layer, the load-bearing capacity and impact resistance of the corrugated paper layer and the honeycomb paper layer are improved. Through the combination of waterproof layer and wear-resistant layer, the overall cardboard has waterproof and wear-resistant functions, improving its practicality. Attached Figure Description

[0025] Example

[0026] Please see Figures 1-4 A composite cushioning modular cardboard structure for paper packaging boxes, comprising:

[0027] Core paperboard 1;

[0028] Two honeycomb paper layers 2 are respectively bonded to the upper and lower surfaces of the core paperboard 1, and a support mechanism 1 is provided inside the honeycomb paper layers 2.

[0029] Two connecting cardboard pieces 3 are respectively glued to two honeycomb paper layers 2;

[0030] Two corrugated paper layers 4 are respectively glued to two connecting cardboard 3, and a support mechanism 2 is provided on the corrugated paper layers 4;

[0031] Two outer cardboard layers 5 are glued to two corrugated paper layers 4 respectively.

[0032] The support mechanism includes multiple support paper rings 6, which are all bonded to the honeycomb paper layer 2. The multiple support paper rings 6 are arranged in pairs, and a support paper tube 7 is bonded to the two support paper rings 6. The two ends of the support paper tube 7 are bonded to the core paperboard 1 and the connecting paperboard 3, respectively. The support paper rings 6 are used to support the honeycomb paper layer 2, thereby improving the strength of the honeycomb paper layer 2. The support paper tube 7 is used to further support and reinforce the support paper rings 6 and the honeycomb paper layer 2, thereby better resisting impact.

[0033] The second support mechanism includes multiple triangular paper tubes 8, which are all bonded to the corrugated paper layer 4. The multiple triangular paper tubes 8 are bonded to the connecting cardboard 3 and the outer cardboard 5 respectively. Three supporting cardboards 9 are bonded inside the triangular paper tubes 8, and paper pillars 10 are bonded between the three supporting cardboards 9. The triangular paper tubes 8 are used to support the corrugated paper layer 4, making the corrugated paper layer 4 more secure. The three supporting cardboards 9 are used to support the triangular paper tubes 8, and the paper pillars 10 are used to centrally support the three supporting cardboards 9.

[0034] One of the outer cardboard layers 5 has a waterproof layer 11 for waterproofing.

[0035] A wear-resistant layer 12 is provided on the waterproof layer 11 to improve wear resistance.

[0036] In summary, the working principle and process of the composite cushioning modular cardboard structure for the paper packaging box are as follows: First, the composite cushioning modular cardboard structure for the paper packaging box is placed at the desired location. Then, during use, the supporting paper tube 7 is glued to the two supporting paper rings 6. Next, the supporting paper tube 7 and the two supporting paper rings 6 are glued to the honeycomb paper layer 2. Then, the core cardboard 1 and the honeycomb paper layer 2 are glued together. The connecting cardboard 3 is glued to the honeycomb paper layer 2. Then, the triangular paper tube 8, paper column 10, and three supporting cardboard 9 are glued together. The triangular paper tube 8 is glued to the corrugated paper layer 4 and then glued to the connecting cardboard 3. Finally, the outer cardboard 5 is glued on and coated with a waterproof layer 11 and a wear-resistant layer 12 on one of the outer cardboard layers 5 to improve waterproof and wear-resistant performance. By filling and supporting the gaps between the corrugated paper layer 4 and the honeycomb paper layer 2, the overall load-bearing capacity and cushioning impact resistance of the device are improved, thus enhancing its practicality.

[0037] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
