Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, specifically to a corrugated cardboard with strong load-bearing capacity. Background Technology

[0002] With the explosive growth of e-commerce, the demand for goods transportation and packaging has increased dramatically. Corrugated cardboard, as one of the most commonly used packaging materials, needs to withstand greater weight and more complex transportation environments. During the stacking, handling, and long-distance transportation of goods, ordinary corrugated cardboard is prone to damage and deformation, failing to meet the reliability and safety requirements of e-commerce logistics. For example, the transportation of large home appliances and furniture requires corrugated cardboard with stronger load-bearing capacity to ensure that the products are not damaged during transportation.

[0003] Traditional corrugated cardboard has a relatively simple corrugation angle and arrangement. When subjected to greater pressure, the pressure is concentrated on some corrugations, which can easily lead to corrugation collapse and cardboard deformation. Its structural design cannot effectively distribute pressure when faced with complex external forces, thus limiting the overall load-bearing capacity. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard with strong load-bearing capacity, which solves the problem that corrugated cardboard is prone to collapse and deformation when subjected to large pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard with strong load-bearing capacity, comprising a corrugating mechanism, wherein the corrugating mechanism comprises a corrugated body, the corrugated body being alternately bent to form a first edge and a second edge, wherein the first edge is convex upward and the second edge is concave downward, a first reinforcing plate is provided in the first edge, a second reinforcing plate is provided in the second edge, and a plurality of reinforcing mechanisms are provided on the upper and lower surfaces of the corrugated body.

[0006] Preferably, the first edge, the first reinforcing plate, the second edge, and the second reinforcing plate are all bent to form a bend, the bend value being between 40° and 55°.

[0007] Preferably, the first reinforcing plate extends to the two ends of a first angular edge, and the second reinforcing plate extends to the two ends of a second angular edge.

[0008] Preferably, both the first reinforcing plate and the second reinforcing plate are mesh plate structures, and both the first reinforcing plate and the second reinforcing plate are made of carbon fiber.

[0009] Preferably, each of the reinforcing mechanisms includes a reinforcing rib, the reinforcing rib having a circular vertical cross-section and meandering over the upper and lower surfaces of the corrugated body, and a reinforcing column is provided inside the reinforcing rib.

[0010] Preferably, the reinforcing rib is coiled in an S-shape, and the bending angle of the reinforcing rib is between 55° and 65°.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a corrugated body, a first edge, a second edge, a first reinforcing plate, a second reinforcing plate, reinforcing ribs, and reinforcing columns, and by setting the first and second reinforcing plates in a mesh-like pattern and embedding them within the first and second edge with an included angle between 40° and 55°, can better distribute pressure across the entire cardboard surface when under pressure, especially when subjected to external forces from different directions, making the force transmission more uniform, thereby improving the overall load-bearing capacity. The reinforcing ribs that meander on the surface of the corrugated body and the reinforcing columns set inside the reinforcing ribs can further increase the load-bearing capacity of the cardboard.
