Abstract

The utility model discloses a kind of corrugated papers, belong to field of papermaking.The device includes upper cardboard, lower cardboard and the core paper being arranged between the upper cardboard and the lower cardboard, the core paper is the thin-wall construction of kidney ellipsoid, its have above depend on face and under depend on face, face is depended on described to be fixedly connected with the upper supporting plate, face is depended under described to be fixedly connected with the lower carrier plate, depended on the core paper of the utility model face and under depend on face and increase contact area between upper cardboard and lower cardboard, gap between reduction core paper, the tension of cardboard and lower cardboard in increase, cross section, which is the core paper of kidney ellipsoid, simultaneously has certain elasticity, two adjacent core papers can mutually exert on reaction force when pushing, make corrugated paper that there is certain elasticity while the compression strength for increasing corrugated paper, increase resiliency.

Description

A kind of corrugated paper

Technical field

The utility model is related to field of papermaking, more particularly to a kind of corrugated paper.

Background technology

Corrugated paper is the plate object that the corrugated paper of the waveform formed by sheet lining and by processing by corrugated roller is bonded, It is generally divided into two class of single wall corrugated board and double-layer corrugated cardboard, is divided into according to the size of corrugation：A, five type of B, C, E, F.Corrugation The invention and application of paper have more than 100 years history history, and at low cost, light weight, processing is easy, intensity is big, printing adaptability sample is excellent It is good, storage convenient in carrying the advantages that, 80% or more corrugated paper can be used as food or number by reclaiming, corrugated paper The packaging of code product, relatively environment-friendly, use is relatively broad.

Form that there are many corrugated papers in the prior art, but the easy bending of generally existing, especially along core paper length direction It is easy bending, some core papers are in the problem of corrugated paper of honeycomb structure overcomes easy bending, but gap is larger between core paper, on Support plate and lower carrier plate are easy to stab out duck eye, in addition, in order to which the structure for increasing the existing corrugated paper of intensity is all to be rushed in rigidity when receiving It when hitting, is easily damaged, and is permanent damage, lack resiliency.

Utility model content

The utility model provides a kind of corrugated paper, can solve the problems, such as pointed in background technology.

A kind of corrugated paper, including upper cardboard, lower cardboard and the core paper being arranged between the upper cardboard and the lower cardboard, The core paper is the thin-wall construction of kidney ellipsoid, have above depend on face and under depend on face, it is described on depend on face and the upper supporting plate It is fixedly connected, face is depended under described and is fixedly connected with the lower carrier plate.

More preferably, further include reinforcing rib, the setting direction of the reinforcing rib and the length direction of the core paper are perpendicular, institute It states reinforcing rib and runs through the core paper, be fixedly connected with the core paper.

More preferably, the reinforcing rib has upper layer and lower layer, and reinforcing rib described in upper layer is fixedly connected with the upper cardboard, lower layer The reinforcing rib is fixedly connected with the lower cardboard.

More preferably, it is covered with plastic film on the upper cardboard.

The utility model provides a kind of corrugated paper, depended on core paper face and under depend on face and increase and upper cardboard and lower paper Contact area between plate reduces gap between core paper, the tension of cardboard and lower cardboard in increases, while the core that cross section is kidney ellipsoid There is paper certain elasticity, two adjacent core papers can mutually exert on reaction force when pushing, increase the compression strength of corrugated paper While make corrugated paper have certain elasticity, increase resiliency.

Description of the drawings

Fig. 1 is a kind of corrugated paper structure schematic diagram one provided by the utility model；

Fig. 2 is a kind of corrugated paper structure schematic diagram two (hiding upper cardboard) provided by the utility model；

Fig. 3 is the front view of Fig. 1.

Reference sign：

The upper cardboards of 10-, cardboard under 20-, 30- core papers, 31- reinforcing ribs.

Specific implementation mode

Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this The protection domain of utility model is not restricted by specific implementation.

As shown in Figure 1 to Figure 3, a kind of corrugated paper that the utility model embodiment provides, including upper cardboard 10, lower cardboard 20 And the core paper 30 being arranged between the upper cardboard 10 and the lower cardboard 20, the core paper 30 are the thin-wall construction of kidney ellipsoid, It has above depend on face and under depend on face, it is described on depend on face and be fixedly connected with the upper supporting plate, depended under described face with it is described Lower carrier plate is fixedly connected.

Further, further include reinforcing rib 31, the length direction of the setting direction of the reinforcing rib 31 and the core paper 30 Perpendicular, the reinforcing rib 31 runs through the core paper 30, is fixedly connected with the core paper 30.

Specifically, the reinforcing rib 31 has upper layer and lower layer, and reinforcing rib 31 described in upper layer is fixed with the upper cardboard 10 to be connected It connects, reinforcing rib 31 described in lower layer is fixedly connected with the lower cardboard 20.

Further, plastic film is covered on the upper cardboard 10, plastic film can further increase 10 He of cardboard The surface tension of lower cardboard 20.

The utility model provides a kind of corrugated paper, depended on core paper 30 face and under depend on face increase and upper cardboard 10 and Contact area between lower cardboard 20, reduces core paper 30 gaps, the tension of cardboard 10 and lower cardboard 20 in increase, while cross section For the core paper 30 of kidney ellipsoid there is certain elasticity, two adjacent core papers 30 can mutually exert on reaction force when pushing, increases Make corrugated paper that there is certain elasticity while the compression strength of corrugated paper, increases resiliency.

Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office It is limited to this, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.

Claims
