Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to high-strength environmentally friendly corrugated paperboards. Background Art

[0002] With the rise of the outer packaging industry and the logistics industry, corrugated boxes have become popular among people due to their low cost, simple processing, convenience and practicality. Corrugated boxes can hold various items, and can also store and transport items, reducing the chance of damage to items.

[0003] Corrugated cardboard is mainly composed of an upper layer of paper, a corrugated core paper and a lower layer of paper. Each layer is bonded together with glue and then made into a cardboard box for holding heavy objects. When carrying heavy objects, the corrugated cardboard is only supported by the wavy corrugated cardboard. After repeated use, its support strength decreases, which affects subsequent use. Utility Model Content

[0005] To achieve the above object, the present invention provides the following technical solution: a high-strength environmentally friendly corrugated paperboard, comprising two upper and lower upper papers, a first corrugated paper core bonded to one side of the upper paper, a lower paper bonded to the other side of the first corrugated paper core, and further comprising;

[0006] A plurality of first corrugated grooves are provided on the upper and lower inner sides of the first corrugated paper core, a plurality of second corrugated paper cores are bonded to one side surface of the first corrugated grooves, and the top of the second corrugated paper core is bonded to the bottom of the upper paper;

[0007] A plurality of second corrugated grooves are arranged on the upper and lower sides of the second corrugated paper core. A cylindrical paper tube is bonded inside the second corrugated grooves. The top of the cylindrical paper tube is bonded to the bottom of the upper paper.

[0008] Preferably, the top paper includes a waterproof layer, a reinforcement layer and a support layer, and the reinforcement layer is bonded between the waterproof layer and the support layer.

[0009] Preferably, the reinforcement layer is a carbon fiber layer, and the support layer is a steel mesh layer.

[0010] Preferably, the first corrugated paper core and the second corrugated paper core are both arranged in a wave shape.

[0011] Preferably, the number of the cylindrical paper tubes corresponds one-to-one to the inner sides of the second corrugated grooves, and the width of the cylindrical paper tubes is the same as the width of the second corrugated paper core.

[0012] Preferably, the upper and lower sides of the second corrugated paper core are respectively fixed to the bottom of the support layer and the inner side of the first corrugated groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model bonds a plurality of second corrugated paper cores to the interior of the first corrugated groove on the inner side of the first corrugated paper core, thereby increasing the stress points of each layer in the corrugated paperboard, further enhancing the overall compressive resistance of the corrugated paperboard, and protecting the integrity of the articles contained in the corrugated paperboard;

[0015] 2. The utility model has a configuration in which a plurality of cylindrical paper tubes are bonded to the inside of the second corrugated groove inside the second corrugated paper core. When the upper paper is pressed, the cylindrical paper tubes are deformed, so that the cylindrical paper tubes and the second corrugated paper core abut against each other, preventing the cylindrical paper tubes from deforming, thereby improving the strength of the corrugated board.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4As shown, the high-strength environmentally friendly corrugated cardboard includes two upper and lower papers 1, the upper paper 1 includes a waterproof layer 101, a reinforcement layer 102 and a support layer 103, the reinforcement layer 102 is bonded between the waterproof layer 101 and the support layer 103, so as to improve the waterproofness and support of the corrugated cardboard, the reinforcement layer 102 is a carbon fiber layer, and the support layer 103 is a steel mesh layer. The carbon fiber layer has high strength and toughness, which can make the corrugated cardboard have strong puncture resistance and pressure resistance, making it not easy to break, which is conducive to the corrugated box carrying heavy objects or carrying them frequently. One side of the upper paper 1 is bonded with a first corrugated paper core 2, and the second The other side of a corrugated paper core 2 is glued to the lower paper 3, and a number of first corrugated grooves 6 are provided on the upper and lower inner sides of the first corrugated paper core 2. A number of second corrugated paper cores 4 are glued to the surface of one side of the first corrugated groove 6, and the top of the second corrugated paper core 4 is glued to the bottom of the upper paper 1. The first corrugated paper core 2 and the second corrugated paper core 4 are both arranged in a wavy shape, and their structures are the same, which can improve the strength of subsequent support and prevent arbitrary deformation. A number of second corrugated grooves 7 are provided on the upper and lower sides of the second corrugated paper core 4, and a cylindrical paper tube 5 is glued to the inside of the second corrugated groove 7, and the top of the cylindrical paper tube 5 is glued to the bottom of the upper paper 1.

[0023] The number of cylindrical paper tubes 5 corresponds one to one with the inner side of the second corrugated groove 7, and the width of the cylindrical paper tube 5 is the same as the width of the second corrugated paper core 4. In this way, when the upper paper 1 is squeezed downward, it is convenient to better support the upper paper 1, thereby improving the overall strength of the corrugated board.

[0024] The upper and lower sides of the second corrugated paper core 4 are respectively fixed to the bottom of the support layer 103 and the inner side of the first corrugated groove 6, so that the second corrugated paper core 4 is conveniently bonded between the upper paper 1 and the first corrugated paper core 2 to prevent the second corrugated paper core 4 from moving.

[0025] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional options in the field, and this technical solution will not further elaborate on them.

[0026] Working principle: When in use, the setting of the upper paper 1 can not only improve the waterproofness of the corrugated cardboard, but also has higher strength and toughness, which can make the corrugated cardboard have strong puncture resistance and pressure resistance, making it not easy to be damaged, which is conducive to the corrugated cardboard box carrying heavy objects or carrying them frequently. At the same time, in the subsequent use process, a number of second corrugated paper cores 4 are bonded to the inside of the first corrugated groove 6 on the inner side of the first corrugated paper core 2, so that the force points of each layer in the corrugated cardboard are increased, and the overall pressure resistance of the corrugated cardboard is further enhanced, and the integrity of the corrugated cardboard for holding items is protected. In addition, pressing the upper paper 1 will also cause the cylindrical paper tube 5 to deform, so that the cylindrical paper tube 5 and the second corrugated paper core 4 abut against each other, preventing the deformation of the cylindrical paper tube 5, thereby improving the strength of the corrugated cardboard.
