Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, and more specifically to a high-strength corrugated paperboard. Background Art

[0002] Cardboard is also called paperboard. It is usually made of various plant fibers, and some are mixed with non-plant fibers, and are made on a cardboard machine. Some special cardboards are also mixed with animal fibers such as wool or mineral fibers such as asbestos. Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard (also called boxboard) bonded together, and has good elasticity and extensibility. It is mainly used to make cartons, sandwiches for cartons, and other packaging materials for fragile goods. It is made of raw cardboard similar to yellow cardboard by beating with traditional straw pulp and waste paper, and then mechanically processed to make it corrugated, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

[0003] However, the existing corrugated paperboard has the following problems when used:

[0004] (1) For some items that need to be transported over long distances or in harsh transportation conditions, ordinary corrugated cardboard cannot provide adequate protection. They are easily affected by external impact and extrusion during transportation. Corrugated cardboard is prone to deformation and cracking, causing damage to the items inside;

[0005] (2) Secondly, when encountering a humid environment, corrugated cardboard is often unable to effectively block the intrusion of moisture. Once moisture enters, the paper fibers will absorb water and swell, resulting in a weakening of the bonding force between the fibers. This makes the cardboard more likely to deform and break when subjected to pressure, stretching or impact, and thus cannot provide sufficient support and protection for the packaged items.

[0006] The utility model can further improve the strength of the corrugated paperboard, so that the corrugated paperboard can buffer and absorb the impact force and block the moisture in a humid environment. Utility Model Content

[0007] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provide a high-strength corrugated paperboard.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength corrugated cardboard, comprising: corrugated core paper, a reinforcing core paper is arranged on the upper end of the corrugated core paper, a buffer plate is glued to the upper end of the reinforcing core paper, the bottom structure sequence of the corrugated core paper is arranged in the opposite order to the upper end, the reinforcing core paper is arranged at the bottom of the buffer plate, and a waterproof film is arranged on the outermost side of the corrugated core paper.

[0009] A further preferred solution is that the wave core paper is arranged in a wave shape as a whole, and suction and pressure columns are arranged at intervals of the wave core paper.

[0010] A further preferred solution: the upper end of the reinforcing core paper is provided with embedding grooves at equal distances, the embedding grooves are arranged in a semicircular shape, and the embedding grooves are nested and connected with the bottom of the buffer plate.

[0011] A further preferred solution is that a filling groove is provided at the outermost side of the fitting groove, and a buffer core is filled in the filling groove.

[0012] A further preferred solution is that support columns are arranged at equal distances at the bottom of the buffer plate, and the support columns are matched with the engaging grooves.

[0013] A further preferred solution is that the waterproof membrane above the corrugated core paper is arranged at the upper end of the buffer plate, and the waterproof membrane below the corrugated core paper is arranged at the bottom of the reinforced core paper below the corrugated core paper.

[0014] Beneficial effects:

[0015] 1. The wave core paper and the pressure absorption column are provided. The pressure absorption column can quickly absorb and bear part of the energy due to its special structure and material. When external force acts, the pressure absorption column deforms first, converting part of the impact energy into its own elastic potential energy, thereby reducing the impact on the wave core paper. The wave core paper bends and deforms when under pressure due to its unique wave shape, further dispersing and buffering the energy. The undulating structure of the wave increases the contact area with the external force, so that the energy can be more evenly distributed on the entire core paper, avoiding excessive local force and causing structural damage;

[0016] 2. The buffer plate and support column are provided. The buffer plate further improves the buffering performance of the corrugated cardboard. When encountering impact or vibration, the buffer plate can absorb and disperse energy. The support column mainly plays the role of enhancing the structural stability and bearing capacity. It can evenly disperse the pressure from above and prevent local excessive force from causing structural deformation or damage;

[0017] 3. By providing the reinforcing core paper and the buffer core, the reinforcing core paper and the buffer core can absorb and disperse the external impact force, reduce the impact on the overall structure, thereby protecting the internal structure from damage, and the reinforcing core paper can provide additional support to help prevent structural deformation or damage;

[0018] 4. In summary, this kind of high-strength corrugated paperboard, by providing structures such as wavy core paper, reinforced core paper and buffer plate, can effectively improve the strength and performance of the paperboard through the reinforced core paper and buffer plate, so that it has good anti-deformation effect when subjected to force and compression in different directions. When encountering impact or vibration, the reinforced core paper and buffer plate can absorb and disperse energy, and the wavy core paper, due to its unique wavy shape, will bend and deform when subjected to pressure, further dispersing and buffering energy, so that the energy can be more evenly distributed on the entire core paper, avoiding local excessive force and causing structural damage.

[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] See also Figure 1-4In an embodiment of the utility model, a high-strength corrugated paperboard comprises: a corrugated core paper 1, a reinforcing core paper 2 is arranged on the upper end of the corrugated core paper 1, a buffer plate 3 is glued to the upper end of the reinforcing core paper 2, the bottom structure sequence of the corrugated core paper 1 is arranged opposite to the upper end, the reinforcing core paper 2 is arranged at the bottom of the buffer plate 3, the outermost side of the corrugated core paper 1 is provided with a waterproof membrane 4, the corrugated core paper 1 is arranged in a corrugated shape as a whole, and suction and pressure columns 101 are arranged at the intervals of the corrugated core paper 1, and the suction and pressure columns 101 are glued and fixed at the intervals of the corrugated core paper 1, so that the suction and pressure columns 101 can absorb the pressure on the upper and lower ends of the corrugated core paper 1, and when absorbing, the suction and pressure columns 101 are squeezed to expand to both sides, and the interior of the suction and pressure columns 101 is solid memory foam, so when squeezed, it will not be broken due to the hollow inside, and after the pressure disappears, due to the particularity of the memory foam, the suction and pressure The column 101 will slowly return to its original shape so that it can continue to absorb pressure and buffer when it is squeezed subsequently. After the pressure absorption column 101 is glued to the corrugated core paper 1, the buffer plate 3 is glued to the upper end of the reinforced core paper 2, so that the bottom of the buffer plate 3 is glued to the upper end of the reinforced core paper 2, and then the glued cardboard is fixed to the upper and lower ends of the corrugated core paper 1 respectively to protect the upper and lower ends of the corrugated core paper 1. At the same time, the corrugated shape of the corrugated core paper 1 itself can also increase the strength of the cardboard itself, which has higher strength than the flat cardboard. At the same time, the reduction in the spacing between the corrugations and the increase in the corrugations will provide better compression and bending resistance, making the cardboard stronger and less prone to damage. At the same time, the waterproof film 4 at the outermost end can effectively waterproof the cardboard to prevent water from entering the inside of the cardboard and soaking the internal structure of the cardboard, causing the cardboard to lose its protective function and its strength to decrease.

[0026] In the embodiment of the utility model, the upper end of the reinforcing core paper 2 is provided with an equidistant embedding groove 201, the embedding groove 201 is arranged in a semicircular shape, the embedding groove 201 is nested and connected with the bottom of the buffer plate 3, the outermost side of the embedding groove 201 is provided with a filling groove 202, the filling groove 202 is filled with a buffer core 203, and the bottom of the buffer plate 3 is provided with support columns 301 at an equidistant distance, and the support columns 301 are matched with the embedding groove 201. When the reinforcing core paper 2 is connected and fixed to the buffer plate 3, the embedding groove 201 is an important structure for nesting and connecting with the support column 301 at the bottom of the buffer plate 3. The embedding groove 201 arranged in a semicircular shape is provided with a filling groove 202 at the outermost side of the embedding groove 201. The filling groove 202 is filled with a buffer core 203, and the support column 301 is arranged at an equidistant distance at the bottom of the buffer plate 3. The support column 301 is matched with the embedding groove 201. When the reinforcing core paper 2 is connected and fixed to the buffer plate 3, the embedding groove 201 is an important structure for nesting and connecting with the support column 301 at the bottom of the buffer plate 3. 01 can better fit the shape of the support column 301 to achieve a tight connection. This tight nested connection can effectively disperse the pressure and improve the overall stability and pressure resistance. The filling groove 202 opened at the outermost side of the fitting groove 201 and the buffer core 203 filled therein further enhance the buffering effect. When subjected to external impact, the buffer core 203 can absorb and mitigate the impact force, and cooperate with the support column 301 to squeeze and expand downward to absorb and buffer the pressure, thereby avoiding local excessive force and causing structural deformation or damage. At the same time, strengthening the core paper 2 helps to enhance the stability and durability of the entire structure.

[0027] In the embodiment of the utility model, the waterproof membrane 4 above the corrugated core paper 1 is arranged at the upper end of the buffer plate 3, and the waterproof membrane 4 below the corrugated core paper 1 is arranged at the bottom of the reinforced core paper 2 below the corrugated core paper 1. The function of the waterproof membrane is to provide waterproof performance and prevent moisture from penetrating into the core paper or other parts. The upper waterproof membrane 4 can protect the buffer plate 3 from moisture to a certain extent, and at the same time, it can also prevent moisture from entering the corrugated core paper 1 and other internal structures from above. The lower waterproof membrane 4 can prevent moisture from coming from below from soaking the reinforced core paper 2 and other parts, thereby maintaining the performance and strength of the overall structure.

[0028] Working principle: When the corrugated core paper 1 is combined with the reinforced core paper 2, the buffer plate 3 and the waterproof film 4 to form a complete corrugated board, the presence of the reinforced core paper 2 significantly enhances the overall compression and tensile resistance of the corrugated board. When it is subjected to heavy objects or external force, it can maintain the stability of the structure with the buffer core 203 and is not prone to deformation or rupture. The buffer plate 3 further enhances the buffering performance of the corrugated board, and can absorb and disperse energy with the support column 301. After absorbing, buffering and dispersing energy layer by layer, the pressure absorption column 101 can quickly absorb and withstand part of the energy and deform to make a Part of the impact energy is converted into its own elastic potential energy, thereby reducing the impact on the corrugated core paper 1. The corrugated core paper 1 bends and deforms when under pressure due to its unique wave shape, further dispersing and buffering the energy. The undulating structure of the wave increases the contact area with the external force, so that the energy can be more evenly distributed on the entire core paper, avoiding structural damage caused by excessive local force, thereby improving the overall strength of the corrugated cardboard. The waterproof film 4 makes the entire corrugated cardboard have good waterproof properties and can effectively block the intrusion of moisture. The internal core paper will not reduce its strength due to moisture.
