Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, in particular to a corrugated paperboard with good pressure resistance. Background Art

[0002] Corrugated paper is currently widely used in paper packaging. It has many advantages such as simple processing, light weight, high strength and hardness, and easy storage. It is becoming more and more popular among outer packaging companies and is widely used in the market for the packaging, storage and transportation of food or digital products. In order to increase the shock resistance and stamping resistance, the corrugated board composed of corrugated paper is generally arranged in multiple layers, separated by core paper in the middle, and the multiple layers of corrugated paper are formed by gluing; for corrugated board used for storage and transportation of special items, the number of corrugated paper layers is usually increased to five, seven or other cardboard structures. Obviously, as the thickness of the corrugated board increases, the strength of the corrugated board also increases.

[0003] Existing corrugated paperboards with good pressure resistance generally use multiple types of corrugated paper to overlap to improve the structural strength, or add elastic blocks to the corrugated paper to improve the strength. When elastic blocks are used for buffering, local uneven force may occur, resulting in local damage to the corrugated paper and reducing the compressive resistance of the corrugated paperboard. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a corrugated paperboard with good pressure resistance to solve the technical problem that uneven local force may occur, resulting in local damage to the corrugated paper.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corrugated paperboard with good pressure resistance, comprising a corrugated mechanism, the corrugated mechanism comprising a lower paperboard, the top of the lower paperboard is fixedly connected to the lower corrugation, the lower corrugation is provided with a through hole, a horizontal tube is arranged inside the through hole, a plurality of the through holes and the horizontal tubes are provided, the plurality of the through holes and the horizontal tubes are linearly and equidistantly arranged, vertical tubes are arranged in the gaps of the lower corrugation, the horizontal tubes and the vertical tubes are connected to each other, and the top of the lower corrugation is fixedly connected to the upper paperboard.

[0006] By adopting the above technical solution, the corrugated cardboard forms a built-in liquid pressure dispersion system by arranging multiple through holes and horizontal tubes in the lower corrugation, as well as vertical tubes in the gaps. When the cardboard is subjected to external pressure, the liquid in the horizontal tubes and vertical tubes can flow freely, thereby dynamically dispersing and absorbing the external pressure, thereby improving the compression resistance of the cardboard.

[0007] Furthermore, the transverse tube and the vertical tube are both made of rubber, and the interior of the transverse tube and the vertical tube are filled with pure water.

[0008] By adopting the above technical solution, the horizontal pipe and vertical pipe made of rubber material can provide good elasticity and pressure resistance, and the rubber pipe can act as a seal to prevent leakage of internal pure water, thereby improving the safety of the equipment.

[0009] Furthermore, baffles are fixedly connected to both sides of the lower paperboard and the upper paperboard, and a liquid filling port is provided inside the baffles.

[0010] By adopting the above technical solution, by fixing and connecting baffles on both sides of the lower paperboard and the upper paperboard respectively, the structural stability and edge strength of the corrugated paperboard can be increased, preventing the edge of the paperboard from being torn or damaged when subjected to external force.

[0011] Furthermore, the liquid adding port and one of the transverse tubes are arranged opposite to each other, and a plug is arranged inside the liquid adding port.

[0012] By adopting the above technical solution, by arranging the liquid adding port opposite to one of the horizontal tubes, it can be ensured that the liquid can smoothly flow into the pressure dispersion system composed of the horizontal tube and the vertical tube, thereby quickly establishing an effective pressure dispersion network.

[0013] Furthermore, the corrugated structures are provided in two groups, and the two groups of corrugated structures are bonded together by glue.

[0014] By adopting the above technical solution, two sets of corrugated structures are bonded together by glue, which can significantly increase the overall thickness and number of layers of the corrugated cardboard, thereby improving its compressive strength and load-bearing capacity.

[0015] Furthermore, the corrugated mechanism is provided with two groups, a steel plate is provided between the two groups of the corrugated mechanism, and the upper and lower sides of the steel plate are bonded to the corrugated mechanism by glue.

[0016] By adopting the above technical solution, by arranging a steel plate between two groups of corrugated mechanisms, the compressive resistance and structural strength of the corrugated board can be significantly improved. As a hard material, the steel plate can effectively disperse the pressure transmitted from the upper corrugated mechanism and evenly transfer it to the lower corrugated mechanism, thereby enhancing the overall pressure balance and load-bearing capacity.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model can construct an effective liquid pressure dispersion system by setting up a corrugated mechanism. By filling pure water into the inside of the horizontal tube and the vertical tube and using the liquid filling port to discharge bubbles, the sealing of the system and the free flow of the liquid are ensured, and the pressure on the corrugated board can be dynamically dispersed and absorbed to improve its pressure resistance. The internal liquid can form a resistance when under pressure, providing additional support for the board on the corrugated board, enhancing the stability of the board, and providing effective buffering when locally under pressure to prevent the board from being damaged due to excessive local pressure;

[0019] 2. The utility model effectively transfers the pressure of the first layer to the second layer by setting a steel plate, thereby achieving uniform distribution of pressure. The hardness of the steel plate enables it to evenly disperse the pressure to the lower layer when subjected to pressure from the upper layer, thereby avoiding the situation where the cardboard is damaged due to excessive local pressure, and ensuring that the corrugated cardboard can be more stable and reliable when subjected to heavy objects or external forces. The steel plate serves as the middle supporting layer, which not only enhances the overall structural strength of the cardboard, but also extends the service life of the cardboard.

[0025] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] Embodiment 1:

[0028] A corrugated cardboard with good pressure resistance, such as Figure 1-Figure 4As shown, the corrugated mechanism 1 includes a lower paperboard 101, the top of the lower paperboard 101 is fixedly connected to a lower corrugated board 102, the lower corrugated board 102 is provided with a through hole 103, a transverse tube 104 is arranged inside the through hole 103, a plurality of through holes 103 and transverse tubes 104 are provided, and the plurality of through holes 103 and transverse tubes 104 are linearly and equidistantly arranged, a vertical tube 105 is arranged in the gap of the lower corrugated board 102, the transverse tube 104 and the vertical tube 105 are connected to each other, an upper paperboard 106 is fixedly connected to the top of the lower corrugated board 102, and the corrugated paperboard is connected to the upper paperboard 106 by a screw thread. A plurality of through holes 103 and transverse tubes 104 are arranged in the lower corrugation 102, and vertical tubes 105 are arranged in the gaps, forming a built-in liquid pressure dispersion system. When the paperboard is subjected to external pressure, the liquid in the transverse tubes 104 and the vertical tubes 105 can flow freely, thereby dynamically dispersing and absorbing the external pressure, thereby improving the pressure resistance of the paperboard. At the same time, the arrangement of the transverse tubes 104 and the vertical tubes 105 also increases the overall structural strength of the paperboard, making it difficult for the paperboard to be deformed or damaged when subjected to pressure, thereby not only improving the pressure resistance of the paperboard, but also extending its service life.

[0029] See also Figure 1 , Figure 2 and Figure 3 The material of the horizontal tube 104 and the vertical tube 105 are both rubber, and the interior of the horizontal tube 104 and the vertical tube 105 is filled with pure water. The horizontal tube 104 and the vertical tube 105 made of rubber can provide good elasticity and pressure resistance. The rubber tube can seal to prevent the internal pure water from leaking, thereby improving the safety of the equipment. At the same time, the pure water filled in the horizontal tube 104 and the vertical tube 105 can flow freely when under pressure. This fluidity helps to further disperse the pressure and form a dynamic support system, thereby ensuring the stable performance of the cardboard under various ambient temperatures.

[0030] See also Figure 1 , Figure 2 and Figure 3 Baffles 107 are fixedly connected to both sides of the lower paperboard 101 and the upper paperboard 106, and a liquid filling port 108 is opened inside the baffle 107. By fixing the baffles 107 on both sides of the lower paperboard 101 and the upper paperboard 106, the structural stability and edge strength of the corrugated paperboard can be increased, and the edge of the paperboard can be prevented from being torn or damaged when subjected to external force. At the same time, the liquid filling port 108 opened inside the baffle 107 is convenient for filling or replenishing liquid into the horizontal tube 104 and the vertical tube 105, maintaining the effectiveness of the liquid pressure dispersion system, and improving the practicality of the corrugated paperboard.

[0031] See also Figure 1 , Figure 2 and Figure 3The liquid adding port 108 and one of the horizontal tubes 104 are arranged opposite to each other, and a plug 109 is arranged inside the liquid adding port 108. By arranging the liquid adding port 108 and one of the horizontal tubes 104 opposite to each other, it can be ensured that the liquid can smoothly flow into the pressure dispersion system composed of the horizontal tube 104 and the vertical tube 105, so as to quickly establish an effective pressure dispersion network. At the same time, the plug 109 is arranged inside the liquid adding port 108, which can effectively close the liquid adding port, prevent liquid leakage, and ensure the stability and durability of the corrugated board during use.

[0032] See also Figure 1 , Figure 2 and Figure 3 The corrugated mechanism 1 is provided with two groups, and the two groups of corrugated mechanisms 1 are bonded to each other by glue. The two groups of corrugated mechanisms 1 are bonded to each other by glue, which can significantly increase the overall thickness and number of layers of the corrugated cardboard, thereby improving its compressive strength and load-bearing capacity. At the same time, the two groups of corrugated mechanisms 1 strengthen the structural stability of the cardboard, making it less likely to be deformed or damaged when subjected to external forces.

[0033] The implementation principle of the utility model is as follows: first, pure water is filled into the interior of the horizontal tube 104 and the vertical tube 105 through the liquid filling port 108, and at the same time, bubbles are discharged through the liquid filling port 108 on the other side baffle, and then the plugs 109 are respectively plugged into the liquid filling ports 108 to plug the outlet of the horizontal tube 104, and the preparation of the equipment is completed;

[0034] When the corrugated cardboard is locally compressed, the local pressure increases, causing the internal liquid to flow around and absorb a certain amount of pressure. Then the internal liquid can also form a resistance to provide support for the corrugated cardboard 106 and improve the pressure resistance of the equipment.

[0035] Embodiment 2:

[0036] See also Figure 4 Two groups of corrugated mechanisms 1 are provided, and a steel plate 2 is provided between the two groups of corrugated mechanisms 1. The upper and lower sides of the steel plate 2 are bonded to the corrugated mechanisms 1 by glue. By arranging the steel plate 2 between the two groups of corrugated mechanisms 1, the compressive resistance and structural strength of the corrugated board can be significantly improved. As a hard material, the steel plate can effectively disperse the pressure from the upper corrugated mechanism and evenly transfer it to the lower corrugated mechanism, thereby enhancing the overall pressure balance and load-bearing capacity. At the same time, the upper and lower sides of the steel plate 2 are bonded to the corrugated mechanism 1 by glue, ensuring the close combination of the components, improving the overall stability and durability of the corrugated board, and preventing the steel plate from moving or dislocating in the board, thereby ensuring the safety and reliability of the corrugated board during use.

[0037] The implementation principle of the utility model is as follows: firstly, the pressure of the first layer can be evenly distributed to the second layer by using the steel plate 2, thereby improving the balance of the pressure.
