Abstract

The utility model provides a simple structure, low in production cost, elasticity is strong, reduce and impale the probability, improve life's high elasticity corrugated paper, from the top down includes following cardboard, corrugated paper layer, higher authority cardboard in proper order, corrugated paper layer's a terminal surface laminating is provided with first elastic layer.

Description

High-elasticity corrugated paper

Technical Field

The utility model relates to a corrugated paper equipment field, in particular to include high elasticity corrugated paper.

Background

The corrugated board has the advantages of good shock resistance, printing, light weight, recyclability and the like, and is widely applied to the fields of product packaging and the like.

At present, the commonly used corrugated board generally forms a three-layer corrugated board structure by outer surface paper on the upper surface and the lower surface and corrugated paper in the middle, has low strength and poor impact resistance, and limits the packaging and transportation of some special products. In order to improve strength and impact resistance, it is common to increase the number of corrugated layers to form a five-layer, seven-layer, or nine-layer structure. Because the thickness of the corrugated board is in direct proportion to the strength of the corrugated board. However, the method has limited effects of improving the strength and impact resistance of the corrugated board, not only wastes resources, but also reduces the packaging space.

Chinese patent CN211942453U discloses a corrugated paper board structure shocks resistance, including facial tissue, corrugated paper, core paper, base stock, the facial tissue with the laminating is fixed with first yarn weaving layer between the corrugated paper, the core paper with from last to laminating in proper order down between the base stock and being fixed with second yarn weaving layer, dampproofing rete, the corrugated paper is located the filling of concave position department between its two adjacent crests and is provided with the honeycomb buffer layer, the corrugated paper is located the filling of its crest and is provided with the silica gel layer. This patent is the simple mode through filling increases the buffer layer, when playing the buffering, can greatly increase the weight of corrugated paper, has increased cost and intensity of labour for transportation, transport.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a simple structure, low in production cost, elasticity is strong, reduce and pierce through the probability, improve life's high elasticity corrugated paper.

In order to realize the technical problem, the utility model adopts the solution that the high-elasticity corrugated paper comprises a lower paper board, a corrugated paper layer and an upper paper board from top to bottom in sequence, and a first elastic layer is arranged on one end surface of the corrugated paper layer in a fitting manner.

The further improvement is that: the bottom surface of the upper paper board is provided with a second elastic layer, the first elastic layer is arranged on the upper end surface of the corrugated paper layer, and the second elastic layer and the first elastic layer form a plurality of triangular structures.

The further improvement is that: the outer end face of the upper paperboard is also provided with a puncture-proof layer.

The further improvement is that: the anti-puncturing layer is oxford.

The further improvement is that: the first elastic layer is made of rubber.

The further improvement is that: the first elastic layer and the second elastic layer are made of rubber.

By adopting the technical scheme, the beneficial effects of the utility model are that: 1. through setting up first elastic layer, second elastic layer to constitute stable triangle-shaped structure, have good elasticity and from resilience ability, improve the intensity and the life of corrugated paper.

2. The anti-puncturing layer is used as the outer end face, the lower paper board is used as the inner end face, and the anti-puncturing layer faces outwards, so that the probability that the upper paper board is punctured due to external force can be reduced, and the impact resistance is further improved.

3. Compare in prior art, under the condition that reaches shock attenuation, buffering effect equally, utilize the advantage of triangle-shaped structure, greatly reduced the weight gain who consequently causes, one reduce the increase of cost, two reduce the increase of transportation cost, the transport labour that consequently brings.

Drawings

Fig. 1 is a schematic structural view of the high-elasticity corrugated paper of the embodiment of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the embodiment of the present invention discloses a highly elastic corrugated paper, which comprises a lower paper board 1, a corrugated paper layer 3, and an upper paper board 2 from top to bottom.

In order to avoid the collapse of the corrugated paper layer 3 caused by external impact and lose the original supporting effect on the lower paper board 1 and the upper paper board 2, the first rubber layer 4 is attached to the upper end face of the corrugated paper layer 3, and when the lower paper board 1 or the upper paper board 2 is subjected to impact force, the corrugated paper layer 3 is subjected to collapse deformation and then acts on the elasticity of the first rubber layer 4 to rebound to restore to the original shape. The service life of the high-elasticity corrugated paper is ensured.

The corrugated paper layer 3 and the first rubber layer 4 are separately manufactured and then fixed together by gluing.

The upper paper sheet 2 and the second rubber layer 5 are manufactured separately and then fixed together by gluing.

In order to further reinforce the corrugated paper layer 3, the bottom surface of the upper paper board 2 is provided with a second rubber layer 5, and the second rubber layer 5 and the first rubber layer 4 form a plurality of triangular structures, so that the structure is more stable, and the impact resistance of the upper paper board 2 is stronger when the upper paper board is used as an outer end surface.

In order to improve the puncture-proof performance of the upper paper board 2, the outer end face of the upper paper board 2 is also provided with a puncture-proof layer 6, and the puncture-proof layer 6 is oxford.

The utility model discloses high elasticity corrugated paper when the carton is being manufactured, in order to prevent to pierce through layer 6 for outer terminal surface, below cardboard 1 be interior terminal surface, prevents piercing through layer 6 outwards, can reduce above cardboard 2 because the probability that external force was pierced improves life. Second rubber layer 5 and first rubber layer 4 constitute a plurality of stabilities and have elastic triangle-shaped structure, can provide stable bearing structure to have certain self-resilience ability, improved the life of corrugated paper.

Modifications and variations of the present invention are within the scope of the claims and are not limited by the disclosure of the embodiments.
