Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, and more specifically, to a high-strength composite corrugated cardboard. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard, and further classified into five types according to the size of the corrugations: A, B, C, E, and F. Corrugated paper has been invented and used for over a century. It boasts advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper can be recycled. It is widely used for packaging food and digital products, is relatively environmentally friendly, and has a broad range of applications.

[0003] While existing corrugated cardboard has a certain compressive strength, it is clearly insufficient when dealing with heavy goods. During transportation, the corrugated core often deforms and collapses, making it difficult to reuse ordinary corrugated cardboard and resulting in a waste of resources. To address these issues, a solution is proposed below. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a high-strength composite corrugated cardboard, which can improve the strength of corrugated paper.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A high-strength composite corrugated cardboard includes a face layer and a corrugated layer. Two face layers are provided, arranged parallel to each other and symmetrically. Reinforcing members are provided on the sides of the two face layers. A corrugated layer is arranged between the two face layers and fixedly connected to each of the two face layers. The cross-section of the corrugated layer is wavy. Multiple cavities are formed between the corrugated layer and the face layer. Supporting members are provided inside each cavity. Each supporting member includes two support plates. One end of each support plate is fixedly connected to the other end of the two support plates, which is fixedly connected to the side of the corrugated layer. The other end of each support plate is fixedly connected to the side of the face layer.

[0007] Preferably, the reinforcement includes a reinforcement layer and a support layer, the reinforcement layer is arranged parallel to one side of the panel layer, the support layer is located between the reinforcement layer and the panel layer, and the support layer, the panel layer, and the reinforcement layer are fixedly connected.

[0008] Preferably, the support layer includes horizontal support strips and vertical support strips. A plurality of horizontal support strips are provided and are evenly arranged. A plurality of vertical support strips are provided and are evenly arranged. The vertical support strips and the horizontal support strips are perpendicular to each other. The horizontal support strips and the vertical support strips are fixedly connected and form a mesh structure.

[0009] Preferably, the opposite sides of the transverse support bar and the longitudinal support bar are evenly provided with a plurality of slots, and the slots of the transverse support bar are interlocked with the corresponding slots of the longitudinal support bar.

[0010] Preferably, the depth of the bayonet is half the height of the corresponding horizontal or vertical support bar.

[0011] Preferably, the two support plates are integrally formed.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This solution improves the support strength between the two panel layers by installing support members between the corrugated layer and the panel layer. At the same time, the support members can support the corrugated layer, reduce its deformation, and thus improve the stress. The design of two support plates can distribute the pressure and ensure support. Meanwhile, the reinforcing members strengthen the panel layer, increase the stress on the panel layer, and reduce the magnitude of the stress deformation of the panel layer, thereby improving the overall strength.

[0014] Second, by having the reinforcing layer in contact with the outside, wear resistance is improved, and by having the supporting layer, the deformation resistance of the reinforcing layer and the panel layer is improved, thereby increasing strength.

[0015] Third, the combination of horizontal and vertical support bars forms a mesh structure, which can support the reinforcing layer. The horizontal and vertical support bars themselves have a certain thickness, which can enhance the resistance to deformation. The snap-fit ​​design allows the horizontal and vertical support bars to be located in the same plane, so that the upper and lower ends of the horizontal and vertical support bars are evenly stressed, ensuring support.

[0016] Fourth, the one-piece molded support plate reduces processing difficulty and facilitates installation. Attached Figure Description

[0024] Example 1:

[0025] Please see Figure 1-5 A high-strength composite corrugated cardboard includes a face layer 1 and a corrugated layer 2. Two face layers 1 are provided, arranged parallel to each other and symmetrically. The corrugated layer 2 is arranged between the two face layers 1 and fixedly connected to each of the two face layers 1. The cross-section of the corrugated layer 2 is corrugated, forming multiple cavities 4 between the corrugated layer 2 and the face layer 1. Support members 5 are provided inside the cavities 4. The support members 5 include support plates 6, of which two are provided. One end of the two support plates 6 is fixedly connected, and the two support plates 6 are integrally formed. The integrally formed support plates 6 are easy to process and reduce processing intensity. The connecting end of the two support plates 6 is fixedly connected to the side of the corrugated layer 2, and the other end of the two support plates 6 is fixedly connected to the side of the face layer 1. Installing support members 5 between the corrugated layer 2 and the face layer 1 improves the support strength between the two face layers 1. At the same time, the support members 5 can support the corrugated layer 2, reduce the deformation of the corrugated layer 2, and thus improve the stress resistance. Furthermore, the design of two support plates 6 can distribute pressure, thereby ensuring support.

[0026] Reinforcing members 3 are provided on the sides of the two panel layers 1. Each reinforcing member 3 includes a reinforcing layer 7 and a supporting layer 8. The reinforcing layer 7 is arranged parallel to one side of the panel layer 1 and is made of kraft paper, providing good wear resistance and a certain degree of water resistance, thus reducing the impact of liquids. The supporting layer 8 is located between the reinforcing layer 7 and the panel layer 1. The supporting layer 8 includes transverse supporting strips 9 and longitudinal supporting strips 10. Several transverse supporting strips 9 are evenly arranged, and several longitudinal supporting strips 10 are evenly arranged, with the longitudinal supporting strips 10 perpendicular to the transverse supporting strips 9. Several slots 11 are evenly provided on the opposite sides of the transverse and longitudinal supporting strips 9, with the depth of each slot 11 equal to the depth of the corresponding transverse or longitudinal supporting strip 9. The horizontal support bar 9 and the corresponding vertical support bar 10 are interlocked at half the height of the support bar 10. The horizontal support bar 9 and the vertical support bar 10 are fixedly connected, forming a mesh structure. The support layer 8, the panel layer 1, and the reinforcement layer 7 are fixedly connected. Through the cooperation of the horizontal support bar 9 and the vertical support bar 10, a mesh structure is formed, which can support the reinforcement layer 7. The horizontal support bar 9 and the vertical support bar 10 themselves have a certain thickness, which can enhance the resistance to deformation. The design of the interlocking 11 can make the horizontal support bar 9 and the vertical support bar 10 located in the same plane, so that the upper and lower end faces of the horizontal support bar 9 and the vertical support bar 10 are evenly stressed, ensuring support.
