Description

Technical Field

[0001] The utility model relates to the field of structural design, in particular to a high-pressure-resistant and shock-absorbing corrugated paperboard. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of corrugated core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] In the packaging material field, corrugated cardboard is widely used in various industries, including logistics, warehousing, and product packaging, due to its excellent pressure resistance, cushioning properties, and low cost. However, with the rapid development of the modern logistics industry, the requirements for packaging materials are also increasing. Traditional corrugated cardboard can no longer meet the high demands in certain scenarios. In particular, when transporting heavy goods or fragile items, traditional corrugated cardboard is easily deformed or even damaged by excessive pressure, making it unable to effectively protect the contents.

[0004] For this reason, in order to obtain better pressure-resistant and shock-absorbing corrugated cardboard, existing manufacturers will choose to stack multiple layers of corrugated paper, or directly use corrugated cardboard with a two-layer paper core structure. In this way, the strength of the corrugated cardboard is guaranteed.

[0005] Although the existing corrugated cardboard has good strength and cushioning performance during actual use, the existing corrugated cardboard has a relatively large overall surface rigidity and lacks a cushioning effect due to its wavy structure. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide a high pressure-resistant and shock-absorbing corrugated cardboard to solve the technical problem that the existing corrugated cardboard has a large overall surface rigidity and lacks a buffering effect due to its wavy structure.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-pressure-resistant and shock-absorbing corrugated cardboard, comprising an upper cardboard, a lower cardboard is arranged below the upper cardboard, a core paper structure is arranged between the upper cardboard and the lower cardboard, the core paper structure is composed of a plurality of first support plates and a plurality of groups of support rods, each group of the support rods is composed of a plurality of second support plates, the first support plates are connected to the upper cardboard and the lower cardboard, the second support plates are connected to the upper cardboard and the lower cardboard, and the first support plates and the second support plates are arranged in a mirror-image manner.

[0008] By adopting the above technical solution, the upper paperboard and the lower paperboard are stably supported by the first support plate and the second support plate that cross in mirror image.

[0009] The present invention is further configured such that a plurality of first limiting holes are provided on the first support plate in conjunction with a plurality of second support plates.

[0010] By adopting the above technical solution, a plurality of second support plates are arranged through the limiting holes so as to pass through the first support plate, so that the second support plates and the first support plates support each other, thereby ensuring the stability of the structure.

[0011] The utility model is further configured such that a second auxiliary plate is provided between the upper paperboard and the lower paperboard at a position higher than the first limiting hole, and a first auxiliary plate is symmetrically provided between the upper paperboard, the lower paperboard and the second auxiliary plate from top to bottom.

[0012] By adopting the above technical solution, the overall strength of the core paper structure is enhanced by providing the first auxiliary plate and the second auxiliary plate.

[0013] The present invention is further configured such that the first auxiliary plate and the second auxiliary plate are fixedly arranged with a plurality of first support plates.

[0014] By adopting the above technical solution, the first auxiliary plate and the second auxiliary plate are fixed by the first supporting plate, and the strength of the first supporting plate is strengthened by the first auxiliary plate and the second auxiliary plate.

[0015] The utility model is further configured such that the first auxiliary plate and the second auxiliary plate are provided with second limiting holes to cooperate with the second supporting plate, and the second auxiliary plate passes through the second limiting holes on the first auxiliary plate and the second auxiliary plate at a certain angle to connect the upper paperboard and the lower paperboard.

[0016] By adopting the above technical solution, the second support plate can be normally fixedly connected to the upper paperboard and the lower paperboard through the second limiting hole, and the first auxiliary plate and the second auxiliary plate provide auxiliary support for the second support plate.

[0017] The present invention is further configured such that the angle between the first support plate and the upper paperboard is 60°.

[0018] By adopting the above technical solution and setting it at a 60° angle, the inner angle of the core paper structure is kept at the most stable angle, ensuring the supporting force of the corrugated cardboard.

[0019] The present invention is further configured such that the opening thickness of the first limiting hole is greater than that of the second support plate.

[0020] By adopting the above technical solution, the second support plate can move to a certain extent, thereby preventing the cardboard from breaking when it is suddenly impacted.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model optimizes the adaptability of the cardboard when subjected to impact by adjusting the angle between the first support plate and the upper cardboard, and controlling the opening thickness of the first limiting hole (greater than the second support plate), while ensuring that the cardboard has good cushioning performance when placing items. In addition, the first support plate, the first auxiliary plate, and the second auxiliary plate support each other to ensure the overall strength of the cardboard. These design details together constitute the uniqueness of the high-pressure-resistant and shock-absorbing corrugated cardboard of the utility model, so that it can meet the high pressure-resistant requirements while also having a good shock-absorbing effect.
