Abstract

The utility model discloses a protective corner post for a cellular board. The protective corner post comprises a core layer and an outer cladding, wherein the core layer is formed by sticking 8 to 10 layers of corrugated boards which are arranged vertically, and wave stripes of the corrugated boards are arranged vertically; and the outer cladding is kraft paper stuck to the core layer. Multilayer corrugated boards are stuck into the solid core layer, so that the bearing strength of the protective corner post is improved; the corrugated boards and the wave stripes thereof are arranged vertically, so that the protective corner post is highest in strength and bearing capacity in the vertical stress direction; the edges of the upper and lower surfaces of the protective corner post are wrapped by using the kraft paper, so that the bonding strength is improved; and the protective corner post is easy to manufacture and is made of waste paperboards, so that waste is changed into valuable, and resource waste is reduced.

Description

Bending block protection corner post

Technical field

The utility model relates to a kind of bending block protection corner post.

Background technology

At present, bending block protection corner post comprises inner sandwich layer and surrounding layer, and its inner sandwich layer adopts two stupefied dividing plates of AB to erect through rolling back group; Its surrounding layer is the PE film paper that sticks on the inner sandwich layer surface; Play dampproof effect, but the deficiency of its existence is that this protection corner post is hollow type; The load-carrying intensity difference can not meet the demands.

Summary of the invention

The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of bending block protection corner post being provided.

For realizing above-mentioned purpose, the utility model adopts following technical proposals:

A kind of bending block protection corner post, it comprises inner sandwich layer and surrounding layer, inner sandwich layer is bonding by the vertically disposed corrugated board of 8-10 layer, and the wave striped vertically is provided with; Surrounding layer is the craft paper that sticks on the inner sandwich layer.

Said craft paper is wrapped in the side all around of inner sandwich layer and the edge of top and bottom.

The beneficial effect of the utility model is:

(1) multi-wall corrugated board is bonded as solid inner sandwich layer, has increased the loading strength of this protection corner post;

(2) corrugated board and wave striped thereof vertical array all makes that its intensity on last lower stress direction is the highest, and bearing capacity is maximum;

(3) craft paper superscribes following edge, can be so that the top and bottom of this protection corner post and panel bonding surrounding layer part when bonding, again can bonding inner sandwich layer part, and increased bonding intensity;

(4) manufacturing process is simple, uses the waste paperboard resources making, is processed into paper article (being the bending block corner post) with scrapping cardboard in the factory, turns waste into wealth, and reduces the wasting of resources.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein 1. inner sandwich layers, 2. surrounding layer, the 3. edge of top and bottom.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Former protection corner post is to process through the outsourcing mode; And there are load-carrying intensity difference, the more high shortcoming of cost; Make a kind of bending block protection corner post now into, as shown in Figure 1, it comprises inner sandwich layer 1 and surrounding layer 2; Inner sandwich layer 1 is bonding by 10 layers of vertically disposed corrugated board, and the wave striped vertically is provided with; Surrounding layer 2 is for sticking on the craft paper on the inner sandwich layer 1.Said craft paper is wrapped in the side all around of inner sandwich layer and the edge 3 of top and bottom.

Method for making: with waiting in the factory that scrapping cardboard collects; Be cut into big or small same size cardboard through repairing sanction machine maintenance; Again through bonding 10 layer paperboards of gluing machine; After delivering to the pre-molding of presenting a theatrical performance as the last item on a programme, cut into the size that needs through guillotine at last, corner post is wrapped up moulding unidimensional craft paper such as cutting with one deck at last.

Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.

Claims

1. a bending block is protected corner post, and it comprises inner sandwich layer and surrounding layer, it is characterized in that, inner sandwich layer is bonding by the vertically disposed corrugated board of 8-10 layer, and the wave striped vertically is provided with; Surrounding layer is the craft paper that sticks on the inner sandwich layer.

2. bending block protection corner post as claimed in claim 1 is characterized in that said craft paper is wrapped in the side all around of inner sandwich layer and the edge of top and bottom.
