Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paperboards, and in particular relates to a corrugated paperboard with a buffer structure. Background Art

[0002] In the modern logistics and packaging industry, corrugated cardboard is widely used in the transportation and packaging of various commodities, such as food, beverages, home appliances, and daily necessities, due to its low cost, light weight, and recyclability. It can be made into cartons, paper boxes, and other packaging containers of various specifications according to the shape, weight, and transportation requirements of different items.

[0003] In existing technologies, corrugated cardboard is usually composed of a simple corrugated interlayer and two layers of cardboard, and its structure is relatively simple. However, during transportation and storage, when faced with external force impact, the cushioning performance of the corrugated cardboard may be poor, making it difficult to effectively protect the items packaged inside. This is especially true for some fragile and delicate goods, such as electronic products and glass products, where even slight collisions or vibrations may cause damage to the items.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a corrugated cardboard with a buffer structure, aiming to solve the problem that the buffering performance of the corrugated cardboard may be poor.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The buffer structure is arranged between the lower cardboard and the upper cardboard, the protective structure is arranged at the corners of the lower cardboard, the upper cardboard is arranged directly above the lower cardboard, and a support structure is arranged between the lower cardboard and the upper cardboard.

[0008] The buffer structure includes a lower hexagonal pad fixedly connected to the top of the lower cardboard, the top of the lower hexagonal pad is fixedly connected to an elastic column, the top of the elastic column is fixedly connected to an upper hexagonal pad, the top of the upper hexagonal pad is fixedly connected to the bottom of the upper cardboard, and a cavity is opened inside the elastic column.

[0009] Preferably, the buffer structure is provided in multiple groups, and the multiple groups of buffer structures are located between the lower cardboard and the upper cardboard in a honeycomb shape. They can deform rapidly when subjected to external force, and convert impact energy into elastic potential energy and store it through compression, bending, etc.

[0010] Preferably, the supporting structure includes a first wave support plate fixedly arranged between the lower cardboard and the upper cardboard, a second wave support plate fixedly connected between the lower cardboard and the upper cardboard, and a connecting plate fixedly connected between the first wave support plate and the second wave support plate to enhance the stability of the internal structure of the corrugated cardboard.

[0011] Preferably, the protective structure includes a triangular block that can be detachably mounted at the corner of the lower cardboard, the outer side wall of the triangular block is fixedly connected to a mounting block, and the mounting block is located between the lower cardboard and the upper cardboard to avoid deformation of the corners of the corrugated cardboard.

[0012] Preferably, rivets are provided on both the lower cardboard and the upper cardboard, and the mounting block is detachably mounted between the lower cardboard and the upper cardboard via the rivets, securing the triangular block at the corners of the lower cardboard and the upper cardboard.

[0013] Preferably, the corners of the lower paperboard and the upper paperboard are provided with fitting grooves, and the triangular blocks are fitted with the lower paperboard and the upper paperboard respectively through the fitting grooves, which facilitates the fitting of the triangular blocks with the lower paperboard and the upper paperboard.

[0014] To sum up, the technical effects and advantages of the utility model are as follows: the corrugated cardboard with a buffer structure increases the structural stability through the action of the supporting structure, making the connection between the lower cardboard and the upper cardboard more stable, and provides a larger buffer space and good elastic recovery energy through multiple groups of buffer structures arranged in a honeycomb shape. Through the action of the cavity, the elastic column is made into a hollow structure, further increasing the elasticity of the elastic column and further reducing the overall weight of the corrugated cardboard, thereby making the structure of the corrugated cardboard more stable, avoiding deformation and collapse of the cardboard, and at the same time absorbing and relieving stress, so that the corrugated cardboard can withstand greater external forces.

[0015] The fitting groove facilitates the movement of the triangular block to fit the corners of the lower and upper cardboards. The installation block and rivets are used together to fix the position of the triangular block, thereby improving the impact resistance of the corners of the corrugated cardboard and avoiding deformation of the corners.

[0025] The present invention provides a corrugated cardboard with a buffer structure. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Reference Figure 1-4 A corrugated cardboard with a buffer structure includes a lower cardboard 1, an upper cardboard 3, a buffer structure 2 for buffering support, and a protective structure 4 for increasing the stability of the corners. The protective structure 4 is provided in four groups, and the four groups of protective structures 4 are respectively located on the corners of the lower cardboard 1 and the upper cardboard 3. The buffer structure 2 is provided between the lower cardboard 1 and the upper cardboard 3. The protective structure 4 is provided at the corners of the lower cardboard 1. The upper cardboard 3 is provided directly above the lower cardboard 1. A support structure 5 is provided between the lower cardboard 1 and the upper cardboard 3. The support structure 5 is provided in six groups, and the six groups of support structures 5 are located inside the lower cardboard 1 and the upper cardboard 3 and distributed in a linear array.

[0027] The buffer structure 2 includes a lower hexagonal pad 21 fixedly connected to the top of the lower cardboard 1, and the top of the lower hexagonal pad 21 is fixedly connected to an elastic column 22. The elastic column 22 is mainly made of rubber material and has a certain elasticity. The top of the elastic column 22 is fixedly connected to an upper hexagonal pad 23. The lower hexagonal pad 21 and the upper hexagonal pad 23 are both supported by plastic material. The top of the upper hexagonal pad 23 is fixedly connected to the bottom of the upper cardboard 3. A cavity 24 is provided inside the elastic column 22. The cavity 24 makes the interior of the elastic column 22 a hollow structure. When the corrugated cardboard is impacted by an external force, the elastic column 22 will rapidly deform and convert the impact energy into elastic potential energy and store it through compression, bending, etc. As the external force continues to act, the elastic column 22 gradually deforms and disperses the energy, thereby reducing the impact force acting on the object. When the external force disappears, the elastic column 22 will gradually return to its original shape under the action of its own elasticity, ready to cope with the next impact.

[0028] Reference Figure 2There are multiple groups of buffer structures 2, and the multiple groups of buffer structures 2 are located between the lower paperboard 1 and the upper paperboard 3 in a honeycomb shape. The honeycomb buffer structure 2 can provide relatively uniform buffering force in all directions.

[0029] Reference Figure 2 The support structure 5 includes a first wave support plate 51 fixed between the lower paperboard 1 and the upper paperboard 3, and a second wave support plate 53 is fixedly connected between the lower paperboard 1 and the upper paperboard 3. The first wave support plate 51 and the second wave support plate 53 are both arranged in a wave shape, and a connecting plate 52 is fixedly connected between the first wave support plate 51 and the second wave support plate 53. The support structure 5 provides additional support for the honeycomb buffer structure 2, further improving the overall compressive resistance of the corrugated paperboard.

[0030] Reference Figure 1 、 Figure 2 and Figure 4 The protective structure 4 includes a triangular block 41 that can be detachably mounted at the corner of the lower cardboard 1. The cross-section of the triangular block 41 is triangular. The outer wall of the triangular block 41 is fixedly connected with a mounting block 42, and the mounting block 42 is located between the lower cardboard 1 and the upper cardboard 3. The triangular block 41 is located at the corner of the lower cardboard 1 and the upper cardboard 3 to avoid deformation of the corner after being subjected to force. The mounting block 42 further increases the connectivity between the lower cardboard 1 and the upper cardboard 3 near the corner. The triangular block 41 is mainly made of hard plastic material with high strength and rigidity, which avoids collapse or distortion of the corners and keeps the shape of the corrugated cardboard stable.

[0031] Reference Figure 1 and 4 Rivets 43 are provided on both the lower cardboard 1 and the upper cardboard 3. The mounting block 42 is detachably mounted between the lower cardboard 1 and the upper cardboard 3 through the rivets 43. After the mounting block 42 is moved between the lower cardboard 1 and the upper cardboard 3, the rivets 43 stabilize the mounting block 42 between the lower cardboard 1 and the upper cardboard 3, thereby fixing the triangular block 41 at the corners of the lower cardboard 1 and the upper cardboard 3.

[0032] Reference Figure 1 、 Figure 2 and Figure 4 The lower paperboard 1 and the upper paperboard 3 are both provided with fitting grooves 44 at their corners, and the triangular blocks 41 are respectively fitted with the lower paperboard 1 and the upper paperboard 3 through the fitting grooves 44. The fitting grooves 44 are arranged in a triangular shape, and the triangular blocks 41 are fitted with the lower paperboard 1 and the upper paperboard 3 through the fitting grooves 44.

[0033] Working principle: First, select two cardboards of the same size (lower cardboard 1 and upper cardboard 3), and install multiple groups of buffer structures 2 in a honeycomb shape between the lower cardboard 1 and the upper cardboard 3, so as to provide a relatively uniform buffering force in all directions. The elastic column 22 is made of rubber material and can deform when impacted by external force, absorb and disperse impact energy. The elastic column 22 is a hollow structure, which enhances the elasticity of the elastic column 22 and, on the other hand, helps to reduce the overall weight of the corrugated cardboard. When the upper cardboard 3 is subjected to external force, the support structure 5 further supports the upper cardboard 3, making the entire buffer structure 2 more firm. The support structure 5 transmits and disperses stress in different directions. After the buffer structure 2 and the support structure 5 are arranged between the lower cardboard 1 and the upper cardboard 3, the triangular block 41 moves through the fitting groove 44 to fit the corners of the lower cardboard 1 and the upper cardboard 3. At this time, the mounting block 42 is located between the lower cardboard 1 and the upper cardboard 3, so that the rivet 43 fixes the mounting block 42, thereby fixing the position of the triangular block 41 to avoid deformation of the corners.
