Technical Field

[0001] The utility model relates to the technical field of paperboards, in particular to an anti-delamination corrugated paperboard. Background Art

[0002] Corrugated cardboard is a common packaging material. It is made of at least one layer of corrugated core paper (also known as middle paper) and two layers of surface paper (inner and outer liner paper) bonded together. It has good compressive strength, cushioning properties and a certain degree of moisture resistance, allowing corrugated cardboard to provide effective protection when transporting and storing goods.

[0003] Existing corrugated cardboard may cause delamination due to poor adhesion, material quality problems or usage environment factors. The existing publication number CN214449036U discloses an anti-delamination corrugated cardboard. By providing fixing blocks and fixing grooves, the adhesive area between the corrugated board and the fixing board is increased, making the fixing of the corrugated board and the fixing board more firmly. However, the fixing board needs to be provided with a specific shape, which is difficult to process. At the same time, after the corrugated cardboard is provided with the fixing board, it will cause the problem of large thickness. Utility Model Content

[0004] The purpose of the utility model is to provide a delamination-resistant corrugated cardboard to solve the problem proposed in the above-mentioned background art that the corrugated cardboard on the current market is more firmly fixed by a corrugated plate and a fixed plate, but the fixed plate needs to be set in a specific shape, which is difficult to process. At the same time, the corrugated cardboard will cause a large thickness after the fixed plate is set.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a delamination-proof corrugated cardboard, comprising a corrugated cardboard main body, wherein a central corrugated cardboard is provided inside the corrugated cardboard main body, and a first toothed cardboard and a second toothed cardboard of the same structure are respectively engaged on both sides of the central corrugated cardboard, and the first toothed cardboard and the second toothed cardboard are relatively meshed with each other, and a surface cardboard and an inner cardboard are respectively provided on both sides of the corrugated cardboard main body, and a second reinforcing cardboard is provided between the inner cardboard and the second toothed cardboard, a first reinforcing cardboard is bonded between the surface cardboard and the first toothed cardboard, and the first and second reinforcing cardboards have the same structure, and first convex plates and second convex plates are respectively provided on opposite sides of the first and second reinforcing cardboards by folding and evenly spaced.

[0006] Preferably, the surface paperboard, the first reinforcement paperboard, the first toothed paperboard, the central corrugated paperboard, the inner paperboard, the second reinforcement paperboard and the second toothed paperboard have the same thickness.

[0007] Preferably, the outer sides of the surface paperboard and the inner paperboard are coated with a first waterproof coating and a second waterproof coating respectively.

[0008] Preferably, the first convex plate and the second convex plate are both folded to form a double-layer paperboard structure, and the double-layer structures of the first convex plate and the second convex plate are respectively bonded and fixed.

[0009] Preferably, one side of the flat end of the first reinforcing paperboard is bonded and fixed to the inner side of the surface paperboard, and the other side of the first reinforcing paperboard and the end of the first convex plate are respectively bonded and fixed to the first toothed paperboard.

[0010] Preferably, one side of the flat end of the second reinforcing paperboard is bonded and fixed to the inner side of the inner paperboard, and the other side of the second reinforcing paperboard and the end of the second convex plate are respectively bonded and fixed to the second toothed paperboard.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the delamination-resistant corrugated cardboard is made of cardboard of uniform thickness, achieving material uniformity, and serrated cardboards are provided on both sides of the central corrugated cardboard. The serrated cardboards mesh with each other, ensuring the structural reliability of the central corrugated cardboard and enhancing the cushioning effect. Furthermore, the serrated cardboards are more reliably connected to the surface cardboard and inner cardboard layers, effectively preventing delamination of the corrugated cardboard. The delamination-resistant corrugated cardboard further includes an inner cardboard layer between the serrated cardboard, the surface cardboard, and the inner cardboard layer. The inner cardboard layer supports the serrated cardboard via raised plates, which also enhance the strength of the corrugated cardboard. BRIEF DESCRIPTION OF THE DRAWINGS
