Technical Field

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself;

[0003] In current technology, corrugated cardboard is usually composed of cardboard and inner core paper. If the force is too great during use, the cardboard will bend. If the strength of the corrugated cardboard is too low, the support and force-bearing capacity will be too low, reducing the use effect. Therefore, it is necessary to design a reinforced corrugated cardboard to solve the above problems. Utility Model Content

[0010] Preferably, the support core and the buffer core are installed alternately between the outer paperboards.

[0012] 1. Through the designed support core and reinforcement frame, the support core is supported between the outer cardboards during use, and the strength and supporting capacity of the corrugated cardboard are strengthened by the support core.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figures 1 to 3The utility model provides a technical solution: a reinforced corrugated paperboard, including an outer paperboard 1, a support core 2 and a buffer core 3 are installed between the outer paperboards 1, the support core 2 includes a support plate 6 and a support frame 7 installed between the support plates 6, a reinforcing plate frame 4 is fixedly installed on the inner surface of the outer paperboard 1, a positioning card slot 5 is opened on the outer surface of the support plate 6, the reinforcing plate frame 4 is engaged with the positioning card slot 5, and the support core 2 is fixed to the outer paperboard 1 by engaging the positioning card slot 5 with the reinforcing plate frame 4. Similarly, the outer paperboard 1 on the other side is installed on the other side of the support core 2, and the outer paperboard 1 on the other side is supported by the support of the support plate 6 and the support frame 7. The strength and supporting capacity of the corrugated cardboard are stronger, reducing the phenomenon of deformation due to stress; the support core 2 and the buffer core 3 are staggered between the outer cardboard 1 to ensure that sufficient support and buffering are provided on the inner side of the outer cardboard 1; the cross-sectional shape of the support frame 7 is set to be X-shaped, and the two ends of the support frame 7 are fixedly connected to the support plate 6, so that the support frame 7 is stably connected to the support plate 6 when in use and sufficient supporting capacity is guaranteed; the shape of the reinforcement plate frame 4 is set to be a cross mesh, and the size and shape of the positioning slot 5 match the size and shape of the reinforcement plate frame 4, so that the reinforcement plate frame 4 can provide a reinforcement effect while being stably connected to the support plate 6.

[0020] From the above description, it can be seen that the utility model has the following beneficial effects: when in use, the support core 2 is supported between the outer cardboards 1, and the strength and supporting capacity of the corrugated cardboard are strengthened by the support core 2, and the reinforcing board frame 4 is installed on the inner side of the outer cardboard 1, and the positioning card slot 5 is used to make the reinforcing board frame 4 engage with the support core 2, and the outer cardboard 1 is strengthened by the reinforcing board frame 4 and the connection between the support core 2 is stable, so that the strength of the corrugated cardboard is higher.

[0021] Example 2: Please refer to Figures 1 to 3 As shown, on the basis of the first embodiment, the utility model provides a technical solution: the buffer core 3 includes a first buffer plate 8 and a second buffer plate 9, the first buffer plate 8 and the second buffer plate 9 are symmetrically installed between the outer paperboard 1, and both sides of the first buffer plate 8 and the second buffer plate 9 are supported on the support core 2, and the buffering capacity of the paperboard is enhanced by the dual supporting effect of the first buffer plate 8 and the second buffer plate 9 when in use; the cross-sectional shape of the first buffer plate 8 and the second buffer plate 9 are both set to an arc shape, and both sides of the first buffer plate 8 are supported on the support plate 6, so that the supporting and buffering capacity of the first buffer plate 8 and the second buffer plate 9 is better.

[0022] By adopting the above technical solution, the first buffer plate 8 and the second buffer plate 9 of the buffer core 3 are symmetrically installed between the outer paperboard 1 when in use, and the two sides of the first buffer plate 8 and the second buffer plate 9 are respectively supported on adjacent support plates 6, thereby ensuring the stability of the installation of the support core 2 while providing support buffering.

[0023] The working principle and use process of the utility model are as follows: during assembly, the reinforcing plate frame 4 is fitted and fixedly installed on the inner side of the outer paperboard 1, and then the supporting core 2 is fixed to the outer paperboard 1 by engaging the positioning card slot 5 on the reinforcing plate frame 4. Similarly, the outer paperboard 1 on the other side is installed on the other side of the supporting core 2. With the support of the supporting plate 6 and the supporting frame 7, the strength and supporting capacity of the corrugated paperboard are made stronger, and the phenomenon of deformation caused by force is reduced. The first buffer plate 8 and the second buffer plate 9 are supported on the supporting plate 6. When the outer paperboard 1 and the support plate 6 are subjected to force, the first buffer plate 8 and the second buffer plate 9 can assist in providing support and buffering capacity, thereby making the supporting capacity of the corrugated paperboard better.
