Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper boards, and in particular to a composite pressure-resistant packaging paper board. Background Art

[0002] Packaging paper board is a sheet material used for packaging items. It is usually made from processed paper and can be used to make various packaging containers, such as cartons, paper boxes, and pads. Packaging paper board is widely used in the packaging of food, beverages, electronic products, daily necessities and other industries to protect goods and facilitate transportation and sales.

[0003] The packaging paper board is made into a pad and placed between products to protect the products to prevent the products from colliding and rubbing against each other during transportation, which may cause surface scratches and damage. It also keeps the products in a stable position inside the packaging to avoid shaking and displacement during transportation.

[0004] When transporting products over long distances, especially over bumpy or vibrating roads or when transporting multiple products, the pads between products are often deformed due to the excessive weight of the products above, causing the products to be squeezed and collided with each other and damaged.

[0024] 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.

[0025] Reference Figure 1-3The utility model provides an embodiment: a composite pressure-resistant packaging paper board, including a cardboard 1. The material of the cardboard 1 is hard cardboard, so that the cardboard 1 has good tensile strength and compressive resistance. A honeycomb panel 6 is bonded to the bottom of the cardboard 1. The honeycomb panel 6 is composed of a plurality of hexagonal honeycombs surrounded by paper sheets. When the cardboard 1 is subjected to external pressure, the pressure will be dispersed to each honeycomb wall so that the pressure on the cardboard 1 can be dispersed, rather than concentrated at a certain point or a local area, thereby improving the compressive resistance of the cardboard 1. The unique honeycomb structure of the honeycomb panel 6 itself has a certain elasticity. When the cardboard 1 is impacted, the honeycomb panel 6 will undergo a certain elastic deformation to absorb and store part of the energy, thereby playing a buffering effect.

[0026] A fiber layer 5 is bonded under the honeycomb panel 6. The fiber layer 5 is made of fiberboard, which can improve the tensile strength of the cardboard 1, especially the lateral strength, making the cardboard 1 more durable and not easy to break or deform. At the same time, because the fiber layer 5 is made of fiberboard, it has a certain elasticity. When the cardboard 1 is impacted or squeezed, it can better absorb and disperse energy, thereby reducing damage to the cardboard 1 when it is impacted.

[0027] A support paper 7 is bonded under the fiber layer 5. The support paper 7 is arranged to have a wavy structure, and the crests of the support paper 7 are bonded to the bottom surface of the fiber cloth, and the troughs of the support paper 7 are bonded to the bottom plate 4. The wavy support paper 7 can evenly disperse the external pressure applied to the cardboard 1 to various parts of the cardboard 1, avoiding rapid damage caused by concentration at a certain point or local area. The above structure can improve the compressive strength and bearing capacity of the packaging paper board. The bottom plate 4 is bonded under the support paper 7. The material of the bottom plate 4 is cardboard, which makes the bottom plate 4 have good tensile strength and compressive resistance. When the bottom plate 4 is fixed to the support paper 7, the cardboard 1 is not easy to bend when subjected to external pressure.

[0028] The edges on both sides of the bottom surface of the fiber layer 5 are bonded to the reinforcing ribs 3, and the bottom surface of the reinforcing ribs 3 is bonded to the edge of the top surface of the bottom plate 4. The reinforcing ribs 3 are made of corrugated paper. When the reinforcing ribs 3 are fixed to the edge between the fiber layer 5 and the bottom plate 4, the supporting paper 7 can be shielded to prevent the edges of the supporting paper 7 from being damaged when under force.

[0029] A reinforcing frame 2 is bonded to the outside of the cardboard 1, the bottom of the reinforcing frame 2 is bonded to the outside of the bottom plate 4, the side panels of the reinforcing frame 2 are bonded to the edges of the honeycomb panel 6, the fiber layer 5 and the supporting paper 7, and the reinforcing frame 2 is set as a rectangular frame structure. The material of the reinforcing frame 2 is cardboard.

[0030] When the reinforcement frame 2 is bonded to the outside of the cardboard 1 and the bottom plate 4, the reinforcement frame 2 can wrap the honeycomb panel 6, fiber layer 5, and support paper 7 between the cardboard 1 and the bottom plate 4, making the edges of the above structure more firm. When the cardboard 1 is subjected to pressure and extrusion, it can better maintain the overall shape and stability of the packaging paper board, thereby improving the compression resistance of the packaging paper board. In addition, the use of the reinforcement frame 2 to protect the edge of the structure between the cardboard 1 and the bottom plate 4 can prevent external moisture from entering the space between the cardboard 1 and the bottom plate 4, thereby avoiding the reduction in strength of the packaging paper board due to moisture, thereby extending the service life of the packaging paper board.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
