Description

Technical Field

[0001] This utility model relates to the field of honeycomb paperboard technology, specifically to a high-strength honeycomb paperboard structure. Background Technology

[0002] Honeycomb paperboard is made based on the principle of honeycomb structure in nature. It is a new type of environmentally friendly and energy-saving sandwich structure material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component - paper core, and then bonding face paper to both sides of it.

[0003] Currently, the common honeycomb paperboard structure on the market usually uses a honeycomb paper core with several honeycomb holes and two sets of face paper attached to the top and bottom of the honeycomb paper core with adhesive to form the overall structure of the honeycomb paperboard. However, the face paper on the top and bottom of the honeycomb paper core is often thin. When it is under pressure and comes into contact with the top of the honeycomb holes on the lower honeycomb paper core, it is easy to leave marks. Furthermore, the structural characteristics of the honeycomb holes also increase the risk of deformation or even damage to the face paper, reducing the structural stability, load-bearing capacity and aesthetics of the honeycomb paperboard. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength honeycomb paperboard structure, which can further improve the structural stability of the paperboard on both sides of the honeycomb paper core, and further improve the overall strength and corresponding load-bearing capacity of this honeycomb paperboard structure.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A high-strength honeycomb paperboard structure includes a honeycomb paper core with a plurality of honeycomb holes and a honeycomb paperboard body formed by face paper adhered to both sides of the honeycomb paper core. A reinforcing plate is adhered at the connection position between the honeycomb paper core and the face paper on both sides. The reinforcing plate includes corrugated cardboard and an interlayer adhered between the corrugated cardboard and the honeycomb paper core.

[0007] Preferably, the corrugated cardboard and interlayer are provided in multiple sets and arranged at intervals, respectively connected to the face paper and the honeycomb paper core.

[0008] Preferably, the corrugated cardboard is arranged in blocks and staggered along the horizontal and vertical directions of the reinforcing plate.

[0009] Preferably, the honeycomb paper core includes a first honeycomb plate that is plate-shaped and a plurality of second honeycomb plates that are strip-shaped and arranged around the periphery of the first honeycomb plate.

[0010] Preferably, the face paper is further provided with creases that are adapted to the arrangement direction of the multiple sets of corrugated cardboard arranged in blocks and the multiple sets of second honeycomb panels arranged around the periphery of the first honeycomb panel.

[0011] Compared with the prior art, this utility model has the following advantages and effects:

[0012] This utility model relates to a high-strength honeycomb paperboard structure. Compared to traditional honeycomb paperboard structures, the addition of reinforcing plates between the honeycomb core and the side linerboards further enhances the structural stability and load-bearing capacity of this honeycomb paperboard structure. Furthermore, by incorporating cardboard or film sandwich structures between the corrugated cardboard and the honeycomb core within the reinforcing plates, the impact resistance and cushioning effect under pressure can be further improved. This also appropriately reduces the deformation and even damage to the corresponding corrugations on the corrugated cardboard, the corresponding honeycomb holes on the honeycomb core, and the side linerboard under pressure, thus enhancing the user experience and appearance of this honeycomb paperboard structure. Simultaneously, the addition of reinforcing plates further improves the waterproof effect of this honeycomb paperboard structure, appropriately extending its service life.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] See Figure 1-2This embodiment relates to a high-strength honeycomb paperboard structure, including a honeycomb paper core 1 with a plurality of honeycomb holes 10 and a face paper 2 attached to both sides of the honeycomb paper core 1 to form a honeycomb paperboard body 100. A reinforcing plate 3 is glued at the connection position between the two sides of the honeycomb paper core 1 and the face paper 2. The reinforcing plate 3 includes a corrugated cardboard 31 and an interlayer 32 glued between the corrugated cardboard 31 and the honeycomb paper core 1.

[0020] Specifically in this embodiment, such as Figure 1 The overall structural configuration of this type of honeycomb cardboard body 100 is shown below, and see also... Figure 2 The diagram shown is a structural disassembly of the honeycomb paperboard core 1, with side linerboards 2 and reinforcing plates 3 on both sides. The reinforcing plates 3, through the corrugated cardboard 31 and interlayer 32 mounted thereon, are respectively adapted and bonded to the linerboard 2 and the honeycomb paperboard core 1 via adhesive, thereby forming... Figure 1 The honeycomb paperboard body 100 shown is an example. Compared to traditional honeycomb paperboard structures, the addition of reinforcing plates 3 between the honeycomb core 1 and the two side sheets 2 further improves the structural stability and load-bearing capacity of the honeycomb paperboard body 100. Furthermore, depending on usage requirements, the interlayer 32, consisting of a paperboard or film structure, between the corrugated cardboard 31 and the honeycomb core 1 within the reinforcing plate 3 can further enhance the impact resistance and cushioning effect of the honeycomb paperboard under pressure. This also appropriately reduces the deformation and even damage to the corresponding corrugations on the corrugated cardboard 31, the corresponding honeycomb holes 10 on the honeycomb core 1, and the side sheets 2 under pressure, thus improving the user experience and appearance of the honeycomb paperboard body 100. Simultaneously, the addition of the reinforcing plates 3 also further improves the waterproof effect of the honeycomb paperboard body 100, appropriately extending its service life.

[0021] The corrugated cardboard 31 and interlayer 32 are provided in multiple sets and arranged at intervals, respectively connected to the face paper 2 and the honeycomb paper core 1, from Figure 1 and Figure 2 As can be seen, this type of honeycomb paperboard body 100 can be further improved in terms of impact resistance and load-bearing capacity between the face paper 2 and the honeycomb paper core 1 through multiple sets of corrugated paperboard 31 and interlayer 32 arranged at intervals in the upper reinforcing plate 3, according to different usage environments and usage needs. This improves the structural stability and overall strength of this type of honeycomb paperboard body 100, reduces the degree of damage to the internal honeycomb paper core 1, and improves applicability and practicality.

[0022] The corrugated cardboard 31 is arranged in blocks and staggered along the transverse and longitudinal directions of the reinforcing plate 3, from Figure 2As can be seen, the corrugated cardboard 31 can be evenly divided into multiple groups and staggered according to the specific size of the honeycomb cardboard. The multiple groups of corrugated cardboard 31 arranged in this way can further improve the impact resistance of the honeycomb cardboard body 100 and the degree of deformation caused to the internal corrugated cardboard 31, interlayer 32 and honeycomb paper core 1 under a certain impact force. At the same time, it can also play a certain buffering and guiding effect for the corrugated cardboard 31 arranged in blocks in the corresponding direction under the stress state in the corresponding direction, and improve the stability and uniformity of the stress in different directions.

[0023] The honeycomb paper core 1 includes a first honeycomb plate 11 in the form of a plate and a plurality of second honeycomb plates 12 in the form of strips arranged around the periphery of the first honeycomb plate 11. For details, please refer to [link to relevant documentation]. Figure 3 As shown, the honeycomb paperboard body 100 can be configured with internal honeycomb paper cores 1 according to actual packaging needs and specific packaging locations. The first honeycomb plate 11 arranged in a plate shape on it can ensure the structural stability of the honeycomb paperboard body 100. At the same time, multiple sets of second honeycomb plates 12 arranged in strip shape surround the outer periphery of the first honeycomb plate 11, which can provide better cushioning effect on the outer edge of the honeycomb paperboard body 100 under pressure, effectively reducing the degree of deformation of the honeycomb paper cores 1 on the outer edge. It also facilitates the connection between multiple sets of honeycomb paperboard bodies 100 and effectively improves the compressive strength of the corresponding honeycomb paperboard body 100 outer edge at the connection position, which is located at the corner, to meet different packaging requirements and storage environments.

[0024] The face paper 2 is also provided with creases 21 that match the arrangement direction of the multiple sets of corrugated cardboard 31 arranged in blocks and the multiple sets of second honeycomb panels 12 surrounding the first honeycomb panel 11. Figure 3 and Figure 4 As can be seen, this type of honeycomb cardboard body 100 can be customized according to actual packaging requirements and its specific packaging location. The face paper 2 can be customized based on the specific structure of the internal honeycomb core 1, the specific positions of the corresponding first honeycomb board 11 and second honeycomb board 12, and the corresponding arrangement direction of the multiple sets of corrugated cardboard 31 arranged in a block-like, staggered pattern. (See also...) Figure 3 and Figure 4Taking the addition of creases 21 on the face paper 2 and the arrangement of the internal honeycomb paper core 1 in the corresponding direction as an example, the addition of creases 21 facilitates the bending and joining process of this honeycomb paperboard body 100 in the corresponding direction according to the packaging requirements at different locations. While meeting different packaging requirements, it can effectively reduce the stress and deformation of the face paper 2, corrugated paperboard 31 and honeycomb paper core 1 during the bending process and in the corresponding state, reduce the cracking phenomenon of the face paper 2, the corresponding corrugated paperboard 31 and the honeycomb paper core 1 during the bending process and in the corresponding bending state, further improve the connection stability of this honeycomb paperboard body 100 structure, meet different storage environments and packaging requirements, and improve the structural flexibility and applicability of this honeycomb paperboard body 100.
