Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard, and more specifically, to a pressure-resistant corrugated paperboard. Background Art

[0002] Corrugated paperboard is composed of two outer papers and a core paper located between the two outer papers. It is a multi-layer adhesive body with good elasticity and extensibility. Many items in life are packaged and transported in boxes made of corrugated paperboard, which has the advantages of low cost, low weight, convenient storage, and recyclability.

[0003] Corrugated paperboard is often made into corrugated boxes for storing and transporting goods. During transportation, the corrugated boxes need to be stacked. The existing corrugated boxes have poor compressive resistance. When stacking heavy items, the corrugated paperboard is prone to bending and deformation, thereby damaging the goods inside the corrugated box.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressure-resistant corrugated paperboard to solve the above problems.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A pressure-resistant corrugated paperboard includes outer papers and a core paper disposed between two outer papers. A clamping member for limiting the two outer papers is sleeved outside the two outer papers. The core paper includes two clamping plates and a corrugated plate located between the two clamping plates. The corrugated plate is bonded to the two clamping plates. Support columns are fixedly connected between the corrugated plate and the clamping plates. A plurality of semi-circular first protrusions are fixedly connected to one end of the two clamping plates away from each other. The first protrusions are bonded to the outer papers.

[0007] The utility model is further provided that: A second protrusion is fixedly connected to the side of the outer paper close to the clamping plate. The second protrusions on the outer paper and the first protrusions on the clamping plate are arranged in an alternating manner and are in contact with each other.

[0008] The utility model is further provided that: Both the first protrusions and the second protrusions are made of rubber material.

[0009] The utility model is further provided that: The support columns are hollow and the support columns are in tight contact with the corrugated plate and the clamping plates.

[0010] The utility model is further provided that: The clamping member includes two vertically arranged baffles, and clamping plates are fixedly connected to the sides of the two baffles.

[0011] The present utility model is further configured such that: a waterproof coating is provided on the sides of the two facial papers away from each other.

[0012] To sum up, the present utility model has the following beneficial effects:

[0013] By arranging corrugated plates in the core paper, the corrugated plates can disperse the impact force and gravity received by the corrugated cardboard to each wave crest and wave trough of the corrugated plates, thereby ensuring that the corrugated cardboard is not easily broken. The support columns and semi-circular protrusions can further improve the overall strength of the corrugated cardboard, and further enable the corrugated cardboard to have good load-bearing capacity, be more pressure-resistant, and not be easily damaged and deformed during transportation.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 As shown, a pressure-resistant corrugated cardboard includes a facial paper 1 and a core paper disposed between two facial papers 1. A waterproof coating is provided on the sides of the two facial papers 1 away from each other. The waterproof coating can improve the waterproof ability of the corrugated cardboard and can effectively prevent the overall strength of the corrugated cardboard from being affected by moisture. A clamping member for limiting the two facial papers 1 is sleeved outside the two facial papers 1. The clamping member can ensure the stability of the connection between the facial paper 1 and the core paper, and at the same time, the clamping member can improve the overall strength of the corrugated cardboard to a certain extent. The clamping member includes two vertically arranged baffles 6, and a clamping plate 7 is fixedly connected to the side surfaces of the two baffles 6. The clamping plate 7 clamps the two facial papers 1 towards each other.

[0020] Please refer to Figure 1 and Figure 2As shown in the figure, the core paper includes two clamping plates 2 and a corrugated plate 3 located between the two clamping plates 2. The corrugated plate 3 is adhered to the two clamping plates 2. The corrugated plate 3 can disperse the impact force and gravity received by the corrugated cardboard to each wave crest and wave trough of the corrugated plate 3, thereby ensuring that the corrugated cardboard is not easily broken. A support column 4 is fixedly connected between the corrugated plate 3 and the clamping plate 2. The support column 4 can further improve the overall strength of the corrugated cardboard, thereby improving the pressure resistance of the corrugated cardboard. The support column 4 is hollow and the support column 4 abuts against the corrugated plate 3 and the clamping plate 2. The hollow support column 4 can reduce the overall mass of the corrugated cardboard while ensuring the strength of the core paper. At the same time, when the corrugated cardboard is subjected to an external impact force, the hollow support column 4 can provide better buffering ability, making the corrugated cardboard not easily damaged.

[0021] Please refer to Figure 2 and Figure 3 As shown in the figure, several semi-circular first protrusions 5 are fixedly connected to the mutually remote ends of the two clamping plates 2. The first protrusions 5 are adhered to the facing paper 1. The first protrusions 5 can further improve the overall strength of the corrugated cardboard. A second protrusion 8 is fixedly connected to the side of the facing paper 1 close to the clamping plate 2. The second protrusion 8 on the facing paper 1 and the first protrusion 5 on the clamping plate 2 are arranged alternately and abut against each other. Both the first protrusion 5 and the second protrusion 8 are made of rubber material, so that both the first protrusion 5 and the second protrusion 8 have good elasticity. The mutually abutting first protrusion 5 and second protrusion 8 can strengthen the overall strength of the corrugated cardboard. When the corrugated cardboard is subjected to a large pressure, opposite elastic forces will be provided between the mutually abutting first protrusion 5 and second protrusion 8, thereby further improving the overall compressive resistance of the corrugated cardboard, and further enabling the corrugated cardboard to have good load-bearing capacity, be more pressure-resistant, and not easily damaged and deformed during transportation.

[0022] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
