Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1 and 3, the shock absorbing carton board provided by the utility model comprises a carton board main body formed by a piece of facial tissue 1 and a shock absorbing layer 2. Wherein, the facial tissue 1 has two-layer, sets up respectively in the top and the bottom of buffer layer 2. The shock-absorbing layer 2 includes an inner liner 21, and both the top and bottom of the inner liner 21 are provided with a core paper interlayer 22. The inner liner 21 includes inner papers 211 arranged vertically symmetrically, and a grid plate 212 for damping is arranged between the symmetrical inner papers 211.

The core paper interlayer 22 comprises a wavy core paper 221, and a plurality of sponge rods 222 for filling are equidistantly arranged on the wavy core paper 221.

In this embodiment, the setting range of the sponge rod 222 is related to the number of undulations of the wavy core paper 221, and the sponge rod 222 is disposed in the groove of the wavy core paper 221 for filling the gap.

In this embodiment, the sponge rod 222 filled in the gap of the wavy core paper 221 in the core paper interlayer 22 not only realizes the damping effect on the cardboard box main body, but also can relieve the stress of the wavy core paper 221 when being extruded, and prolong the service life of the wavy core paper 221.

The working principle of the damping carton board based on the first embodiment is as follows: when the cardboard box board main body is assembled, the sandwich layers 22 of the core paper distributed on the two sides of the inner liner 21 in the shock absorption layer 2 are assembled first. When the sandwich 22 is assembled, a plurality of sponge rods 222 are sequentially arranged at the grooves of the wavy sandwich 221, and then are adhered by glue. When the core paper sandwich 22 is assembled, it is then attached to the corresponding side wall of the inner liner 21 by gluing. And then bonding the facial tissues 1 on the shock absorption layer 2 to realize the assembly of the cardboard box plate main body.

When the cardboard box board main body is subjected to the pressing force, the outermost core paper sandwich layer 22 in the shock absorbing layer 2 is subjected to force, and then it transmits the force to the inner liner layer 21, and then the inner liner layer 21 transmits the force to the inner core paper sandwich layer 22. Efficient weakening of the force is achieved via three layers of damping. When the stress of the cardboard body is within an acceptable range, the sponge rods 222 in the sandwich paper layers 22 which are released on the two sides of the inner liner layer 21 in the shock absorption layer 2 can be automatically recovered, so that the cardboard body can recover to an initial state after being stressed, and the service life of the cardboard body is prolonged.

Example two

As shown in fig. 2, based on the first embodiment, this embodiment further includes: grid 212 is formed from a plurality of X-shaped paper shells connected together. The plurality of inner papers 211 are respectively attached to the corresponding case walls of the louver 212 by adhesive.

In this embodiment, the grid plate 212 formed by connecting a plurality of X-shaped paper shells is bonded to the back paper 211 to form the inner liner 21. The inner liner 21 not only can improve the overall stability and structural strength of the carton board, but also can enhance the damping effect thereof.

Example III

As shown in fig. 3, based on the first or second embodiment, the present embodiment further includes: the groove of the wavy core paper 221 is integrally provided with a positioning block 223, and the vertical section of the positioning block 223 is in a rectangular structure. A positioning groove is formed in one side, close to the wavy core paper 221, of each sponge rod 222, and a positioning groove is inserted between each positioning groove and the corresponding positioning block 223 for limiting. The positioning block 223 is connected with the sponge rod 222 through adhesive. The facial tissue 1 and the wavy core paper 221 are adhered by glue.

In this embodiment, the positioning blocks 223 are matched with the positioning grooves on the sponge rods 222, so that when the core paper sandwich 22 is assembled, the sponge rods 222 are sequentially adhered to the wavy core paper 221 through glue.

In this embodiment, the insertion between the positioning groove and the positioning block 223 further enhances the adhesion stability between the sponge rod 222 and the wavy core paper 221 when the sponge rod 222 is adhered to the wavy core paper 221 by glue.

In this embodiment, when the shock absorbing layer 2 is adhered to the facial tissue 1, the sponge rod 222 adhered to the wave-shaped core paper 221 is also adhered to the facial tissue 1.

The above-described embodiments are merely a few preferred embodiments of the present utility model, and many alternative modifications and combinations of the above-described embodiments will be apparent to those skilled in the art based on the technical solutions of the present utility model and the related teachings of the above-described embodiments.
