In order to more clearly understand the technical solution provided by the embodiments of the present application, a brief description is first given to an existing corrugated carton containing a large amount of tobacco leaves.

In the prior art, a container for containing bulk tobacco leaves is generally a seven-layer corrugated carton made of seven-layer corrugated paper boards, and compared with a common three-layer corrugated carton or a five-layer corrugated carton, the strength of the corrugated carton is better.

However, in the production practice, the tobacco leaves after being transported are generally stacked in a stacking manner, and the whole corrugated case is neatly stacked in a designated area. In this case, the lowermost corrugated box bears the weight of all the boxes in the upper part thereof and the tobacco leaves therein. When the weight of the upper part is too large, the side parts of the carton below the upper part are bent, and when the weight is too large, the carton is seriously deformed, so that the tobacco leaves inside the carton are crushed.

The bottom of the upper carton is not flat, so that the force applied to the lower carton is not uniformly applied to the sides of the lower carton, and when the gravity of the upper carton is applied to the lower carton through a certain region or a certain point, the stressed region of the lower carton is deformed, and the position adjacent to the stressed region is deformed, and the sides of the lower carton are bent accordingly.

In order to solve the above-mentioned technical problem, an embodiment of the present application provides a high strength corrugated cardboard, referring to fig. 1 and fig. 2, the high strength corrugated cardboard includes a reinforced core paper 10 and side paper boards 20 adhered to two sides of the reinforced core paper 10, the reinforced core paper 10 includes a mesh-shaped framework 11, a plurality of stress through holes 112 in a diamond shape are formed in the mesh-shaped framework 11, the plurality of stress through holes 112 are distributed in a rectangular array, corrugated paper blocks 12 are respectively formed inside the plurality of stress through holes 112, side walls of the corrugated paper blocks 12 are tightly attached to inner walls of the stress through holes 112, two sides of the corrugated paper blocks 12 respectively extend out of two sides of the mesh-shaped framework 11, and the two side paper boards 20 are respectively adhered to two sides of the corrugated paper blocks 12.

Further description is provided below with respect to specific usage scenarios.

The method is characterized in that the stress of paper boards during stacking of the paper boxes in daily production practice is simulated, and when a target paper box receives the weight of a plurality of paper boxes and goods on the upper portion of the target paper box, four side walls of the paper box bear the pressure of the weight of the upper portion directly. When the target carton side wall is the high strength corrugated cardboard provided in the embodiments of the present application, the pressure is directly applied to the side wall 20 and the side wall edge of the reinforced core paper 10.

The mesh skeleton 11 is in a mesh shape, and when the pressure is directly pressed to the mesh skeleton 11, the mesh skeleton 11 can disperse the pressure to other positions of the mesh skeleton 11, so that the whole mesh skeleton 11 is stressed together. The reason is that the net-shaped framework 11 is composed of a plurality of rod pieces, the plurality of rod pieces are distributed in a net shape to form the net-shaped framework 11, most of the rod pieces are in point or surface connection, when a certain rod piece is stressed, other rod pieces connected with the certain rod piece are stressed accordingly, and the stress is transmitted to other rod pieces connected with the certain rod piece, so that the stress is dispersed, and the high-strength corrugated board can bear higher stress.

Limited by the net structure, the net-shaped framework 11 is provided with a plurality of stress through holes 112, the inside of each stress through hole 112 is provided with a corrugated paper block 12, and the probability of deformation of the rod piece on the net-shaped framework 11 is reduced when the net-shaped framework 11 bears stress by the corrugated paper block 12, so that the net-shaped framework 11 can bear more stress.

In general, the embodiment of the application uses the mesh core paper, so that the stress applied to the corrugated board can be dispersed and uniformly distributed on other parts of the corrugated board, the occurrence of the condition that the stress is concentrated to one point or a certain area is reduced, the structural strength of the corrugated board is improved, and the bearing capacity of the corrugated board is further improved.
