Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper, in particular to a novel double-corrugated paper core corrugated paper. Background Art

[0002] Corrugated paper, also known as corrugated cardboard, is a multi-layer composite adhesive structure. It is composed of at least one layer of wavy core paper interlayer and one layer of cardboard. These core papers and cardboards are arranged side by side in a row, supporting each other, and cleverly forming a stable triangular structure. This unique structure gives corrugated paper excellent mechanical strength. In the plane direction, it can withstand a considerable degree of pressure and exhibits excellent compressive resistance. At the same time, corrugated paper also has good elasticity and its buffering effect is very significant. In the process of transporting goods, whether it is an accidental collision or an accidental fall, corrugated paper can play an excellent protective function and effectively protect the internal items from damage. For this reason, corrugated paper is widely used in many fields. Among them, in the packaging of electronic products, corrugated paper can effectively buffer external impacts and protect delicate electronic components; in food packaging, it can ensure that food remains intact during transportation and ensure food safety. In short, corrugated paper plays an indispensable and important role in the packaging industry with its unique structure and performance.

[0003] A novel high-strength double-corrugated paper core corrugated paper with a publication number of CN 214777930 U is retrieved. By setting a strengthening mechanism, when the corrugated paper is subjected to external force during use, after the outer plate is subjected to force, force is applied to the fiberboard, the outer plate and the fiberboard are deformed, part of the impact force is consumed, and part of the impact force is offset. When the fiberboard is deformed, the support column moves toward the board core after being subjected to force, and through the transmission of two transmission rods, the two support rings move in opposite directions on the support rod, compressing the spring on the support rod, and part of the impact force is consumed again, and part of the impact force is offset again, so that the deformation of the corrugated paper when subjected to external force is greatly reduced, and the structural strength of the corrugated paper is indirectly improved, so that the corrugated paper has high-strength performance;

[0004] The shortcomings of the new type of high-strength double-corrugated core corrugated paper in the above comparative example: although a reinforcement mechanism has been set up to increase the structural strength of the corrugated paper, in actual application scenarios, corrugated paper usually needs to be cut into various protective outer boxes according to specific needs, but such operation often leads to a problem, that is, during the cutting process, it is easy to cut the position where the reinforcement mechanism is located, so that the reinforcement mechanism originally used to enhance the structural strength is damaged, which leads to a significant decrease in the overall structural strength of the corrugated paper. In addition, in some storage environments with high humidity, this type of corrugated board may become soft and deformed due to absorbing too much water, which greatly reduces its original support and protection function. For example, during transportation, if it encounters humid weather such as rain, the corrugated board may quickly become damp due to poor waterproofing effect, resulting in a sharp decrease in its strength and inability to effectively protect the goods inside.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a novel double-corrugated paper core corrugated paper, comprising two surface papers 1 and a reinforcing structure 2 located in the middle of the two surface papers 1, and a waterproof structure 3 closely fitted with the reinforcing structure 2;

[0021] The reinforcing structure 2 includes two corrugated boards 21 and a tight plate 22 located in the middle of the two corrugated boards 21. The tight plate 22 is bonded between the two corrugated boards 21. The opposite sides of the two corrugated boards 21 are provided with U-shaped blocks 23 distributed in a linear array. Plug-in grooves 24 are left between the U-shaped blocks 23. The top and top of the tight plate 22 are provided with plug-in blocks 25 adapted to the plug-in grooves 24.

[0022] The above scheme is adopted: through the design of the reinforcement structure 2 and the waterproof structure 3, the two corrugated boards 21 and the tight board 22 in the middle are matched with each other, and the overall stability and pressure resistance are enhanced by the design of the U-shaped block 23, the plug-in groove 24 and the plug-in block 25. The butter paper 31 has good water-proof performance and can effectively block the invasion of external moisture, while the absorbent cotton 32 can absorb the trace moisture that may penetrate, further enhancing the waterproof effect. In addition, the waterproof coating sprayed on the outer wall of the face paper 1 forms multiple waterproof guarantees, which can effectively prevent moisture from intruding and avoid paper damage due to moisture, thereby extending the service life of the corrugated paper, so that it can maintain good performance in various environments, and provide more reliable protection for the internal items. Specifically, the design of the two corrugated boards 21 fundamentally increases the strength of the device, and the plug-in groove 24 left between the U-shaped blocks 23 is adapted to the plug-in block 25. When the plug-in block 25 is inserted into the plug-in groove 24, they are tightly fitted together, thereby increasing the strength of the corrugated paper by increasing the overall density.

[0023] like Figures 1 to 5 As shown, the waterproof structure 3 includes butter paper 31 bonded to the opposite sides of the two face papers 1 and absorbent cotton 32 located in the middle of the U-shaped block 23 and bonded to the corrugated board 21. The outer walls of the two face papers 1 are sprayed with a waterproof coating.

[0024] The above scheme is adopted: the waterproof coating is the first layer of protection that is also in direct contact with the outside world. When the rainfall is too heavy, rainwater may penetrate in. At this time, the butter paper 31 can effectively block the invasion of external moisture through its good waterproof performance. When the butter paper 31 is slightly cracked, the absorbent cotton 32 can absorb the trace moisture that may penetrate in, thereby achieving a waterproof effect.

[0025] like Figures 1 to 5 As shown, the U-shaped blocks 23 arranged on opposite sides of the two corrugated boards 21 are bonded to the top surface and the bottom surface of the compact board 22 respectively.

[0026] According to the above solution, the U-shaped blocks 23 are bonded to the corrugated board 21 , and the U-shaped blocks 23 are evenly distributed on the corrugated board 21 .

[0027] like Figures 1 to 5 As shown, the two face papers 1 and the corrugated board 21 are equidistantly and symmetrically distributed with the compacting board 22 as the midpoint.

[0028] The above solution is adopted: the two corrugated boards 21 increase the material thickness and support level of the top and bottom of the device. For example, when heavy objects are stacked or squeezed by objects above, the top can effectively disperse and resist the pressure to avoid dents or deformation. At the bottom, when the device is placed on various surfaces, whether it is a flat ground or a slightly uneven contact surface, the enhanced strength provided by the two corrugated boards 21 can ensure that the bottom firmly supports the weight of the entire device and the items inside it, and will not easily bend or break.

[0029] The working principle and use process of this utility model:

[0030] First, through the exquisite cooperation between the two corrugated boards 21 and the tight board 22 in the middle, a unique structural combination is achieved. In this combination, after the plug-in block 25 is inserted into the corresponding plug-in slot 24, they can fit together tightly. This tight fit greatly increases the connection tightness between the components, thereby effectively improving the overall density. The increase in overall density directly brings about a significant improvement in the strength of the corrugated paper, enabling it to better withstand various external forces and pressures. In terms of waterproofing, the waterproof coating serves as the first line of defense and is also an important layer of protection for direct contact with the external environment. When encountering excessive rainfall, although the waterproof coating can play a certain blocking role, strong rainwater may still penetrate. At this time, the butter paper 31 stands out with its good water-proof performance and can effectively prevent further intrusion of external moisture. Even in extreme cases, the butter paper 31 is slightly broken, and the absorbent cotton 32 can also play a key role in absorbing the trace moisture that may penetrate.
