Description
Technical field
The invention belongs to corrugated board processing technique field, more specifically, it relates to a kind of combined corrugated board and its
Processing method.
Background technology
Corrugated board has low light weight, cost, easy processing, easy to storing up as most important, most widely used packaging material
The advantages that depositing and transporting, this is that and the stupefied shape structure such as its U, V, UV also carries significantly not available for timber packaging and mental package
The high resistance to compression of carton, resistance to broken ability.It has very high mechanical strength, can support collision in by handling process and fall and fall, be existing
The necessary material of generation packaging.
The more undulates of corrugated paper of corrugated board of the prior art are horizontally arranged in corrugation sandwich layer, this structure
Paperboard structure intensity difference, in use corrugated board often deformed upon because of compression, can not adapt in handling process
Different impacts, be easy to cause corrugated board internal layer and does not work, or even damage, influences the safety of packed article.Therefore need
A kind of new technical solution is proposed to solve the above problems.
The content of the invention
In view of the deficienciess of the prior art, the purpose of the present invention one is to provide a kind of combined corrugated board, it is above-mentioned multiple
Closing corrugated board has good resistance to deformation, shock resistance, extends the service life of above-mentioned combined corrugated board.
To achieve the above object, the present invention provides following technical solution：A kind of combined corrugated board, including facial tissue layer,
Corrugation sandwich layer and inner paper layer, the inner paper layer and facial tissue layer are located at the interior outside of corrugation sandwich layer respectively, and the corrugation sandwich layer includes
The corrugated board sheet composition of some continuous wave-likes of row, is equipped with least two pieces reinforcement paper between the facial tissue layer and inner paper layer
Plate, the side of every piece of reinforced paperboard are fixedly connected on facial tissue layer, its opposite side is fixedly connected on inner paper layer, described watt
The stupefied scraps of paper are filled in by the reinforced paperboard, the reinforced paperboard and facial tissue layer, the reinforced paperboard and inner paper layer or described
In the cavity that reinforced paperboard, facial tissue layer and inner paper layer are formed, and it is bonding with the cavity inner wall.
By using above-mentioned technical proposal, reinforced paperboard is added in combined corrugated board, on the one hand adds corrugation
The thickness of paper so that the integral hardness of combined corrugated board increases；On the other hand the both sides of corrugated board sheet are connected to interior
Ply of paper and facial tissue layer, also play the effect of support inner paper layer and facial tissue layer as corrugated board sheet.Thereby increase above-mentioned multiple
Anti- deformation and the impact resistance of corrugated board are closed, extends the service life of combined corrugated board so that above-mentioned corrugated paper is more
What is added is firm and durable.
The present invention is further arranged to：Often arrange and form section between the corrugated board sheet and the facial tissue layer or inner paper layer
In continuous semicircle or half-oval shaped supporting structure.
By using above-mentioned technical proposal, above-mentioned corrugated board sheet bends to continuous semicircle or half-oval shaped, at this time
Continuous curved circular shape, not only increases the thickness of corrugated paper, while multiple semicircle or semiellipse arc structures have
Good cushion performance, can effectively reduce the probability that cavity deforms between inner paper layer and facial tissue layer, so as to improve above-mentioned multiple
Close the firmness and durability of corrugated board.
The present invention is further arranged to：Often arrange to form between the corrugated board sheet and the facial tissue layer or inner paper layer and replace
Semi-conical supporting structure.
By using above-mentioned technical proposal, above-mentioned corrugated board sheet bends to alternate semi-conical structure, at this time half-conical
Curved surface there is certain cushion performance, the probability that cavity between inner paper layer and facial tissue layer deforms can be effectively reduced, so as to carry
