Description

Seven layers of corrugated container board of shock-resistant are resisted to high elasticity

Technical Field

The utility model relates to a paper technical field, especially a seven layers corrugated container board of high elasticity impact resistance.

Background

With the rapid development of national economy and the great improvement of the living standard of people in China, various electric products with different functions also continuously enter the lives of people, and because the electric products are sensitive to collision and impact, the electric products need to be protected by a packing box in the circulation process and are convenient to transport and store, and certain requirements are provided for the strength of the paper packing box for better protecting and storing the electric products.

The existing carton is generally made of corrugated boards, but the impact resistance of the carton made of the common corrugated boards is poor, and external vibration is easily transmitted to electric appliances placed in the carton, so that the electric appliances in the carton are unnecessarily damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a seven layers of corrugated container board of shock-resistant are strikeed to high elasticity for the carton that uses this kind of corrugated container board to make has better buffering effect, can fully absorb external energy, prevents that the electrical apparatus is shaken badly in the carton.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a high-elasticity impact-resistant seven-layer corrugated board comprises a first corrugated paper layer, a first bubble film layer, a second corrugated paper layer, a corrugated paper core layer, a third corrugated paper layer, a second bubble film layer and a fourth corrugated paper layer which are sequentially arranged from top to bottom; support strips are arranged in gaps between the corrugated paper core layer and the second corrugated paper layer and between the corrugated paper core layer and the third corrugated paper layer; the supporting bars comprise buffer tubes and supporting columns which are axially arranged in parallel along the buffer tubes; the buffer tube supports tightly in the trough setting of corrugated paper sandwich layer, the support column supports tightly on second corrugated paper layer or third corrugated paper layer with the one end that the buffer tube is not connected.

Further, the buffer tube is made of PVC foam.

Furthermore, the support column is composed of a plurality of frustum platforms which are gradually reduced, and the interior of the support column is hollow.

Further, the support column is made of plastic.

Furthermore, the air bubbles in the air bubble film layer are of a honeycomb structure, and the size of the air bubbles is 3-6 mm.

Has the advantages that: through set up the bubble rete respectively between first corrugated paper layer, second corrugated paper layer and third corrugated paper layer, fourth corrugated paper layer, make the utility model discloses possess better buffer function, work as promptly the utility model discloses when receiving great impact, the bubble rete can carry out the energy-absorbing deformation, prevents that outside effort from transmitting to inside electrical apparatus on, makes inside electrical apparatus accept the damage. Simultaneously, be provided with the support bar respectively in the clearance between corrugated paper sandwich layer and second corrugated paper layer, corrugated paper sandwich layer and third corrugated paper layer, this support bar can have certain rigidity, can guarantee that corrugated paper sandwich layer can not the atress warp and lose buffering effect. Simultaneously, buffer tube and support column in the support bar all have certain buffer function, can play a similar spring's effect.

Reference numerals: 1. the corrugated paper comprises a first corrugated paper layer 2, a first bubble film layer 3, a second corrugated paper layer 4, a corrugated paper core layer 5, a third corrugated paper layer 6, a second bubble film layer 7, a fourth corrugated paper layer 8, a support bar 81, a buffer tube 82 and a support column.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The seven-layer corrugated board with high elasticity and impact resistance shown in fig. 1 and 2 comprises a first corrugated paper layer 1, a first bubble film layer 2, a second corrugated paper layer 3, a corrugated paper core layer 4, a third corrugated paper layer 5, a second bubble film layer 6 and a fourth corrugated paper layer 7 which are arranged from top to bottom in sequence and bonded by glue; wherein first corrugated paper layer and fourth corrugated paper layer, second corrugated paper layer and third corrugated paper layer are the kraft paper material, and in order to increase the wearability of the first corrugated paper layer, the fourth corrugated paper layer that are in the outside, can coat one side polyvinyl acetate in the outside of first corrugated paper layer, fourth corrugated paper layer. In addition, the first bubble film layer and the second bubble film layer are made of the same PVC bubble film material.

Meanwhile, the supporting bars 8 are respectively arranged in the gaps of the corrugated paper core layer facing the second corrugated paper layer and the corrugated paper core layer facing the third corrugated paper layer. Specifically, the supporting bar is composed of a buffer tube 81 and a plurality of supporting columns 82 which are arranged on the buffer tube side by side and uniformly. Wherein, the support bar sets up along corrugated paper sandwich layer medium wave length direction, and its surface supports tightly in corrugated paper sandwich layer's trough. And one end of the support column, which is not connected with the buffer tube, is abutted against the second corrugated paper layer or the third corrugated paper layer on two sides of the corrugated paper core layer. So that the support strip plays a supporting role. In this embodiment, the outer diameter of the buffer tube is the same as the diameter of the corrugated paper core at the trough of the corrugated paper core, so that the buffer tube and the corrugated paper core are in tangential contact.

On the basis of this embodiment, it is preferred, in order to reduce the utility model discloses a weight, the buffer action of still remaining the assurance buffer tube simultaneously of convenient transportation, the buffer tube adopts PVC foam material.

On the basis of the present embodiment, preferably, the supporting column is formed by stacking a plurality of frustums which are gradually reduced, and in order to reduce the production cost and increase the elastic deformation capability, the supporting column is internally provided with a hollow structure.

In the present embodiment, it is preferable that the support column is made of plastic material, such as PPS, PA66, PEEK, PAI, PEI, etc., in order to ensure the strength of the support column and reduce the weight of the support column.

On the basis of this embodiment, preferably, in order to guarantee the intensity of bubble rete to and bubble rete has better energy-absorbing effect, the bubble in the bubble rete is honeycomb structure and distributes, and the size of bubble is between 3~6 mm.
