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 anti-folding corrugated board shown in fig. 1 to 4 comprises corrugated paper 100, and a plurality of first through holes 110 are uniformly formed on the corrugated paper. Meanwhile, two reinforcing strip groups 200 perpendicular to the corrugated strips 120 of the corrugated paper penetrate through the corrugated paper, and the reinforcing strip groups are arranged symmetrically to the corrugated paper. It should be noted that the reinforcing bar group 200 is composed of at least two reinforcing bars 210, and second through holes 220 corresponding to the first through holes on the corrugated paper one by one are formed on the reinforcing bars. In addition, two sides of the corrugated paper are respectively bonded with a first piece of face paper 300 through glue, and the first face paper is provided with third through holes 310 corresponding to the first through holes one to one. A reinforcing pin 400 is inserted into the corrugated paper 100, the reinforcing strip 210 and the first face paper 300 through the third through hole, the second through hole and the first through hole. In order to prevent the reinforcing pins from moving, spokes 430 are respectively disposed at the first end 410 and the second end 420 of the reinforcing pins, and the spokes are respectively fixed on the first face paper so that the reinforcing pins and the first face paper are integrated. It should be noted that in order to facilitate production of the spokes to be unfolded after the reinforcing pins are inserted through the corrugated paper 100, the reinforcing strips 210 and the first face paper 300, the spokes 430 connected to the first end 410 have a shorter length than the spokes provided at the second end. Under the structure, if the corrugated board is stressed transversely to bend, the reinforcing strip group penetrating into the corrugated paper also needs to bend adaptively in the bending process, and it should be noted that, because the reinforcing strip group is not positioned on the central line of the corrugated paper, the reinforcing strip group inevitably needs to stretch or move in the bending process to adapt to the length change required by bending. However, the reinforcing strips are non-extensible materials, so that the reinforcing strips are required to move in the corrugated paper to compensate for the insufficient length during bending, but because the movement of the reinforcing strips in the corrugated paper is prevented by the existence of the reinforcing pins, the corrugated paper board is subjected to resistance from the reinforcing strips during bending, and the folding resistance of the corrugated paper board is correspondingly improved. In addition, the acting force transmitted to the reinforcing pins by the reinforcing bars is uniformly transmitted to the first face paper by the spokes, so that the acting force borne by the corrugated board is uniformly distributed, and the effect of improving the anti-folding capacity of the corrugated board can be achieved.

As a further improvement of the above embodiment, in order to improve the integrity between the reinforcing bar set 200 and the reinforcing pins 400 and the first face paper and the corrugated paper, a layer of hot melt net 500 is laid on the side of the first face paper 300 opposite to the corrugated paper. During production, the hot-melt net is laid on the first face paper 300, and then the reinforcing pins penetrate through the hot-melt net, the first face paper, the corrugated paper and the reinforcing strip set. After the operation is finished, the hot melt net is hot melted by hot air, at the moment, the spokes 430 on the reinforcing pins are in hot melt connection with the molten hot melt net, and the hot melt net is simultaneously bonded on the first surface paper. This kind of connected mode has the advantage that the fastness of connection is big and effort conduction dispersion. The bending resistance of corrugated board can be greatly improved.

As a further improvement of the above embodiment, in order to further improve the folding resistance, a layer of second face paper 600 covering the hot melt net 500 and the spokes 430 is provided on the side of the first face paper 300 facing away from the corrugated paper. Be connected through the viscose between this second facial tissue and the first facial tissue, receive the power back that the enhancement pin conducted and come when first facial tissue because second facial tissue and first facial tissue bond, consequently the effort that first facial tissue received can be shared to the second facial tissue.
