Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to an environmentally friendly, pressure-resistant spiderweb-shaped corrugated cardboard. Background Art

[0002] Corrugated cardboard is a packaging material made of paper, widely used in transportation, storage, and display. Due to its recyclability, biodegradability, low carbon emissions, and resource conservation, corrugated cardboard is a highly environmentally friendly packaging material. It possesses excellent strength, pressure resistance, and protective properties, making it an important material in modern logistics and packaging industries. Existing corrugated cardboard typically consists of three layers of paper. The middle layer is corrugated cardboard, providing support and protection, while the outer layer is usually flat. Although the corrugated middle layer supports the outer layers, its overall strength is relatively low, resulting in poor pressure resistance. Therefore, we propose an environmentally friendly, pressure-resistant spiderweb-shaped corrugated cardboard. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an environmentally friendly, pressure-resistant spiderweb-shaped corrugated cardboard.

[0004] The technical solution of this utility model is as follows: an environmentally friendly, pressure-resistant spiderweb-shaped corrugated cardboard, comprising an outer cardboard, an inner cardboard on one side of the outer cardboard, a corrugated assembly between the outer cardboard and the inner cardboard, the corrugated assembly comprising multiple sets of vertical pressure-resistant flutes, a reinforcing flute frame between every two sets of vertical pressure-resistant flutes, each set of vertical pressure-resistant flutes comprising multiple sets of vertical flutes, a bending flute between every two sets of vertical flutes, each set of reinforcing flute frames comprising reinforcing flutes, and multiple sets of supporting flute frames on both sides of the reinforcing flutes.

[0005] Preferably, the two sides of the corrugated assembly are respectively bonded to the outer cardboard and the inner cardboard on the side closest to each other.

[0006] Preferably, the two ends of the bending rib are respectively installed close to one end of the two sets of vertical ribs, and each set of bending ribs is provided with an inclined surface.

[0007] Preferably, the bent ribs on the two sets of vertical compression ribs that are close to each other are honeycomb-shaped.

[0008] Preferably, the two sides of the reinforcing frame are respectively attached to one side of the two sets of vertical anti-compression ribs.

[0009] Preferably, the mounting end of each set of support frames is installed corresponding to the reinforcing rib, and the support frames are arranged in a "V" shape.

[0010] Preferably, the end of the support frame away from the reinforcing rib is fitted to the inclined surface.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This utility model has a simple overall structure. It consists of an outer cardboard, an inner cardboard, and a corrugated assembly combined to form a corrugated cardboard. The overall strength of the cardboard is enhanced by the vertical anti-compression flutes and the reinforcing flute frame. At the same time, the strength of the corrugated assembly is enhanced by the supporting flute frame and the inclined surface, thereby improving the compression resistance of the corrugated cardboard.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-4As shown, this utility model proposes an environmentally friendly, pressure-resistant spiderweb-shaped corrugated cardboard, comprising an outer cardboard 1, an inner cardboard 2 disposed on one side of the outer cardboard 1, and a corrugated assembly 3 disposed between the outer cardboard 1 and the inner cardboard 2. The two sides of the corrugated assembly 3 are respectively bonded to the outer cardboard 1 and the inner cardboard 2 on their respective adjacent sides. The corrugated assembly 3 includes multiple sets of vertical pressure-resistant flutes 31, each set of vertical pressure-resistant flutes 31 including multiple sets of vertical flutes 311. A bending flute 312 is disposed between every two sets of vertical flutes 311. The vertical flutes 311 and the bending flutes 312 are fixedly connected. The two sets of vertical flutes close to each other... The bending ribs 312 on the compression-resistant flutes 31 are honeycomb-shaped. The two ends of each bending rib 312 are respectively installed close to one end of two sets of vertical flutes 311. Each set of bending ribs 312 has a bevel 313. The bevel 313 increases the contact area between the vertical compression-resistant flutes 31 and the outer cardboard 1 and inner cardboard 2. The multiple sets of vertical compression-resistant flutes 31 enhance the strength between the outer cardboard 1 and the inner cardboard 2, thereby improving the compression resistance of the corrugated cardboard. A reinforcing flute frame 32 is provided between every two sets of vertical compression-resistant flutes 31. The two sides of each reinforcing rib 32 are respectively attached to two sets of vertical compression ribs 31, close to each other on one side. The two sides of each reinforcing rib 32 are respectively bonded to the two sets of vertical compression ribs 31. Each set of reinforcing ribs 32 includes a reinforcing rib 321. Multiple sets of supporting ribs 322 are provided on both sides of the reinforcing rib 321. The mounting end of each supporting rib 322 is installed corresponding to the reinforcing rib 321. The mounting end of the supporting rib 322 is fixedly connected to the reinforcing rib 321. The supporting rib 322 is set in a "V" shape. The end of the supporting rib 322 away from the reinforcing rib 321 is connected to the inclined... The surfaces 313 are fitted together, and the "V"-shaped setting of the support frame 322 can abut against the inclined surface 313 on the bending frame 312, thereby improving the strength of the vertical compression-resistant frame 31. The overall structure of this utility model is simple. The outer cardboard 1, inner cardboard 2 and corrugated assembly 3 are combined to form corrugated cardboard. The setting of the vertical compression-resistant frame 31 and the reinforcing frame 32 can enhance the overall strength of the cardboard. At the same time, the setting of the support frame 322 and the inclined surface 313 can enhance the strength of the corrugated assembly 3, thereby improving the compression resistance of the corrugated cardboard.

[0021] In this embodiment, the operator first glues a set of vertical compression-resistant ribs 31 onto the inner cardboard 2, and then aligns one side of the reinforcing rib 32 with the vertical compression-resistant rib 31. At this time, one side of the reinforcing rib 321 is in contact with the vertical rib 311, and the supporting rib 322 abuts against the inclined surface 313 of the folded rib 312. Then, the subsequent vertical compression-resistant ribs 31 and reinforcing rib 32 are laid out in an array one by one. Finally, the outer cardboard 1 is attached to the side of the corrugated assembly 3 away from the inner cardboard 2.

[0022] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
