Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to a high-elasticity peak-shaped double-wall corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a structural material composed of multiple layers of paper, commonly used for packaging and transporting goods. Corrugated cardboard boasts advantages such as high strength, lightweight, environmental friendliness, low cost, and customizability. Due to its excellent physical properties and economic efficiency, it is widely used globally and is one of the essential materials in the modern packaging industry. Most existing corrugated cardboard consists of one or more corrugated cores sandwiched between two flat linerboards. This structure makes it lightweight and provides good compressive strength. However, the overall structural elasticity of existing corrugated cardboard is relatively low. When encountering impacts, it cannot effectively buffer the impact force, easily damaging the goods it protects. Therefore, we propose a highly elastic peak-shaped double-wall corrugated cardboard. Utility Model Content

A high-elasticity corrugated core is disposed at the position of the flat corrugation core on each set of single-sided corrugated core strips. A second corrugated core is disposed between every two sets of first corrugated cores, each set of second corrugated cores includes two sets of single-sided corrugated core strips, each set of single-sided corrugated core strips includes multiple sets of arc corrugations and flat corrugations.

[0021] Example

[0022] like Figure 1-6 As shown, this utility model proposes a high-elasticity peak-shaped double-wall corrugated cardboard, comprising two sets of face sheets 1, with multiple sets of first corrugated cores 2 disposed between the two sets of face sheets 1. Each set of first corrugated cores 2 includes two sets of single-sided corrugated core strips 21. The upper and lower sides of each set of single-sided corrugated core strips 21 are respectively attached to one side of the two sets of face sheets 1. The single-sided corrugated core strips 21 are arranged in a wavy shape. The two sets of single-sided corrugated core strips 21 are arranged opposite each other. The opposite arrangement of the two sets of single-sided corrugated core strips 21 can make the first corrugated core 2 as a whole have higher elasticity. The first corrugated core 2 is arranged in an elastic peak shape. Each set of single-sided corrugated core strips 21 includes multiple sets of concave corrugations 211 and flat cores 212. One end of the corrugated core 211 is installed correspondingly to one end of the flat core 212. The concave corrugated core 211 is fixedly connected to the flat core 212. One side of the flat core 212 on each set of single-sided corrugated core strips 21 is glued to the face paper 1. Each set of single-sided corrugated core strips 21 is provided with a high-elastic corrugated core 4 at the position of the flat core 212. The outer periphery of the high-elastic corrugated core 4 is respectively attached to the concave corrugated core 211 and the flat core 212 on the two sets of single-sided corrugated core strips 21. The outer periphery of the high-elastic corrugated core 4 is glued to the concave corrugated core 211 and the flat core 212. The setting of the high-elastic corrugated core 4 enhances the strength of the first corrugated core 2 and improves the elasticity of the first corrugated core 2, thereby improving the buffering performance of the first corrugated core 2 after being impacted.

[0023] A second corrugated core 3 is provided between every two sets of first corrugated cores 2. Each set of second corrugated cores 3 includes two sets of single-sided corrugated core strips 31. The upper and lower sides of each set of single-sided corrugated core strips 31 are respectively attached to one side of the two sets of face paper 1. The single-sided corrugated core strips 31 are arranged in a wavy shape. The two sets of single-sided corrugated core strips 31 are arranged opposite each other. The opposite arrangement of the two sets of single-sided corrugated core strips 31 can improve the elasticity of the single-sided corrugated core strips 31. The second corrugated core 3 is arranged in an elastic peak shape. Each set of single-sided corrugated core strips 31 includes multiple sets of curved ribs 311 and flat ribs 312. One end of the curved rib 311 is installed corresponding to one end of the flat rib 312. The curved rib 311 and the flat rib 312 is fixedly connected. The two sets of single-sided corrugated core strips 31 are bonded to each other at the position of the flat rib 312. Each set of single-sided corrugated core strips 31 is provided with a reinforcing rib 5 near the position of the flat rib 312. The outer side of the reinforcing rib 5 is respectively bonded to the arc rib 311 and the flat rib 312 on the single-sided corrugated core strip 31. The outer side of the reinforcing rib 5 is bonded to the arc rib 311 and the flat rib 312. The side of the reinforcing rib 5 away from the single-sided corrugated core strip 31 is bonded to the side of the face paper 1. The side of the reinforcing rib 5 is bonded to the face paper 1. The setting of the reinforcing rib 5 can enhance the overall strength of the second corrugated core 3 and improve the impact resistance of the second corrugated core 3.

[0024] The concave rib 211 on the first corrugated core strip 21 corresponds to the flat rib 312 on the second corrugated core strip 31. The flat rib 212 on the first corrugated core strip 21 corresponds to the arc rib 311 on the second corrugated core strip 31. Multiple sets of first corrugated cores 2 and multiple sets of second corrugated cores 3 are arranged in an alternating manner. The alternating arrangement of the first corrugated cores 2 and the second corrugated cores 3 can enhance the overall strength of the corrugated cardboard and improve its elasticity, thereby enhancing the impact resistance of the corrugated cardboard.

[0025] In this embodiment, the operator integrates the concave corrugation 211 and the flat core 212 to form a single-sided corrugated core strip 21. Then, the two sets of single-sided corrugated core strips 21 are glued together in a facing position. The high-elasticity corrugated core 4 is then glued between the two sets of single-sided corrugated core strips 21. The curved corrugation 311 and the flat corrugation 312 are then integrated to form a single-sided corrugated core strip 31. The two sets of single-sided corrugated core strips 31 are then glued together in a facing position. The reinforcing corrugated core 5 is then glued to the flat corrugation 312 position on the two sets of single-sided corrugated core strips 31. The single-sided corrugated core strips 21 and 31 are then laid out in an alternating array on one side of a set of face paper 1. Finally, another set of face paper 1 is glued to the other side of the first corrugated core 2 and the second corrugated core 3 to complete the production of a high-elasticity peak-shaped double-wall corrugated cardboard.

[0026] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
