Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated paperboard field, concretely is a kind of anti-deformation corrugated paperboard. BACKGROUND

[0002] As important material of packaging industry, corrugated paperboard is widely used in the packaging of various products due to its low cost, light weight, recyclability and other advantages. However, traditional corrugated paperboard has many problems in actual use, among which the deformation problem is particularly prominent.

[0003] During transportation, the packaging made of traditional corrugated paperboard is prone to deformation due to bumps and vibrations during vehicle travel, as well as uneven pressure when goods are stacked. This not only affects the appearance integrity of the packaging, but also may cause the internal products to be damaged due to extrusion and collision. For example, in electronic product packaging, deformation of corrugated paperboard packaging may cause internal precision electronic component pins to bend and circuit board to break, resulting in product failure.

[0004] In terms of warehousing, long-term stacking and storage will cause the bottom corrugated paperboard to bear a large pressure, and the traditional structure cannot effectively resist such pressure, resulting in paperboard indentation and bending, which seriously affects the protection performance of the packaging. Moreover, traditional corrugated paperboard is sensitive to environmental humidity. When the environmental humidity is high, the paperboard is prone to absorb moisture, resulting in a significant decrease in strength and further deformation. According to statistics, the compressive strength of traditional corrugated paperboard stored in a humid environment decreases by an average of 30%-50%. Therefore, we propose an anti-deformation corrugated paperboard. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model provides an anti-deformation corrugated paperboard to solve the above problems.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an anti-deformation corrugated paperboard, comprising two surface layers, each of which is provided with a plurality of intermediate support structures on one side corresponding to each other, and the intermediate support structures on both sides are arranged in an upper-lower mirror image staggered manner, and the adjacent two staggered surface layers are mutually adhered.

[0007] Preferably, the surface layer comprises surface paper and a plastic film, and the plastic film is compounded on the surface of the surface paper.

[0008] Preferably, the intermediate support structure is composed of an I-shaped support and two side support plates, the I-shaped support is composed of a short plate, a long plate and a vertical plate, the long plate and the short plate are connected by the vertical plate, the two sides of the vertical plate are respectively provided with inclined side support plates, and the two ends of the side support plates are respectively located between the side walls corresponding to each other of the long plate and the short plate.

[0009] Preferably, the long plate and the short plate are provided with arc-shaped notches at positions corresponding to the side support plates, and the side support plates are integrally formed with arc-shaped protrusions corresponding to the arc-shaped notches, and the arc-shaped protrusions are connected with the arc-shaped notches.

[0010] Preferably, the connection between the long plate and the vertical plate is fixedly provided with an inclined inclined support, and the end of the inclined support is fixedly provided with an end transverse plate, and the end transverse plate is attached to the side support plate.

[0011] Compared with the prior art, the anti-deformation corrugated paperboard has the following beneficial effects:

[0012] Significant improvement in compression resistance and deformation resistance

[0013] The unique intermediate support structure cooperates with the I-shaped support and the two inclined side support plates to work when subjected to pressure, and can disperse and conduct the pressure at multiple angles. The long plate and the short plate of the I-shaped support provide stable support in the horizontal direction, the vertical plate connects the long plate and the short plate to enhance the overall stability, and the inclined arrangement of the side support plate greatly increases the stress area and the support angle of the support structure, effectively resisting the bumps and vibrations during transportation and the pressure during storage stacking, preventing the paperboard from being concave and bent, ensuring the integrity of the package, and reducing the risk of internal products being squeezed and damaged by collision.

[0014] The arc-shaped notches and the arc-shaped protrusions between the long plate, the short plate and the side support plate are connected by the clamping design, which prevents the side support plate from being dislocated and ensures that the entire support structure remains stable when subjected to pressure, further improving the compression resistance and deformation resistance of the corrugated paperboard.

[0015] Good environmental adaptability

[0016] The plastic film of the surface layer is compounded on the surface paper to form an effective waterproof and moisture-proof barrier. In a humid environment, water erosion of the paperboard can be greatly reduced, and deformation caused by strength reduction due to water absorption can be avoided. According to experimental tests, compared with traditional corrugated paperboards, the average compression strength of the anti-deformation corrugated paperboard can be controlled within 10% under the same humidity environment, which greatly improves the use reliability under different environmental conditions.

[0017] Cost advantage and light weight

[0018] Instead of using the simple and crude method of increasing the thickness or the number of layers of the paperboard to improve the strength, the performance is enhanced by optimizing the structural design, which effectively controls the cost while ensuring the anti-deformation effect. Compared with the traditional improvement scheme of increasing the thickness or the number of layers, the amount of material used is not significantly increased, which reduces the cost of raw materials.

[0019] The overall structure is reasonable in design, weight is not excessively increased due to pursuit of strength, conforms to the development trend of modern packaging lightening, is favorable for reducing transportation cost and energy consumption, and has obvious advantages in the logistics transportation link.

[0020] High processing and production feasibility

[0021] The materials (surface paper, plastic film and materials constituting the intermediate support structure) used are common materials in the packaging industry, are widely sourced and have good compatibility between the materials. Whether it is composite plastic film to surface paper or assembly of the intermediate support structure, the processing technology is relatively mature, without the need to invest in a large number of new equipment and complex process improvement, is conducive to large-scale production and is conducive to rapid application to actual packaging production.

[0037] Composition: composed of an I-shaped support 5 and two side support plates 7. The I-shaped support 5 is composed of a short plate, a long plate and a vertical plate, and the long plate and the short plate are connected by the vertical plate.
