Abstract

The utility model discloses a multi-layer corrugated board, which mainly comprises corrugated box boards, an upper layer of wave corrugation, a lower layer of wave corrugation and an air bag rod, wherein the upper layer of wave corrugation and the lower layer of wave corrugation are arranged between the upper layer of corrugated box board and the lower layer of corrugated box board, the upper layer of wave corrugation and the lower layer of wave corrugation are both in sine wave shape, and the air bag rod is arranged at the position of a wave trough and a wave crest in each half period of the upper layer of wave corrugation and the lower layer of wave corrugation; air is slightly blown into the air bag rod with certain compressibility, the air bag rods arranged in the upper layer of wave corrugations and the lower layer of wave corrugations are in staggered direct contact, and the air bag rods are deformed under the action of external force to generate air pressure counter force. Has the advantages that: the corrugated box board without the intermediate partition board is designed, the thickness of a multi-layer corrugated box board is reduced, the air bag rods arranged between the upper layer and the lower layer or between the multi-layer corrugated box board and the multi-layer corrugated box board are mutually extruded when external force is generated to deform, the overall upward resultant force is generated, and the compressive strength of the overall box board is improved.

Description

Multilayer corrugated container board

Technical Field

The utility model belongs to the production and packaging field, concretely relates to multilayer corrugated container board.

Background

Corrugated paper is a plate-shaped object formed by bonding corrugated paper of corrugated shapes formed by processing of liner paper and corrugated rollers, generally divided into single corrugated paper boards and double corrugated paper boards, and divided into the following two types according to the size of the corrugated paper: A. b, C, E, F five types. The invention and application of the corrugated paper have more than one hundred years history, have low cost, light weight, easy processing, intensity big, printing adaptability is good, store and carry advantages such as convenient, more than 80% of the corrugated paper can be recycled, the corrugated paper can be used as the packing of food or digital products, relatively environmental protection, use comparatively extensively. At present, multilayer corrugated boxboards are seen everywhere, and one problem is that when a manufacturer tries to increase the strength of the corrugated boxboards, the thickness of the corrugated boxboards is increased, namely the strength of the corrugated boxboards is improved in a linear relation with the thickness of the corrugated boxboards, and the corrugated boxboards with environmental protection, high strength and small thickness need to be designed to meet the same requirement.

Disclosure of Invention

Not enough more than to, the utility model discloses the device provides a multilayer corrugated container board.

The utility model discloses the technical scheme that its technical problem was solved to the device adopted is: the multilayer corrugated board mainly comprises corrugated box boards, upper-layer wave corrugations, lower-layer wave corrugations and an air bag rod, wherein two layers of the upper-layer wave corrugations and the lower-layer wave corrugations are arranged between the upper-layer corrugated box board and the lower-layer corrugated box board, the upper-layer wave corrugations and the lower-layer wave corrugations are both in sine wave shapes, and the air bag rod is arranged at the positions of wave troughs and wave crests in each half period of the upper-layer wave corrugations and the lower-layer wave corrugations; air is slightly blown into the air bag rod with certain compressibility, the air bag rods arranged in the upper layer of wave corrugations and the lower layer of wave corrugations are in staggered direct contact, and the air bag rods are deformed under the action of external force to generate air pressure counter force.

The working principle is as follows: the inside main upper wave flute that is by of at first the double-deck (or multilayer) corrugated container board that sets up, lower floor's wave flute is constituteed, the baffle layer in the middle of in the past has been abandoned, effectively reduce the whole thickness of boxboard, both sides wave flute about arranging on this basis, and at wave flute crest, the gasbag stick is all installed to the trough position, upper and lower two-layer gasbag stick direct contact, it is fixed to extrude each other, when receiving the exogenic action, upper and lower two-layer wave flute takes place to warp, lead to the gasbag stick to be compressed each other, inside air pressure increases, produce atmospheric pressure reverse force, the gasbag stick between upper and lower two-layer wave flute all produces, it leaves to obtain one total direction of resisting external force, the structural strength of whole corrugated container board has been.

The utility model discloses the technical scheme who provides of device is useful: the corrugated box board without the intermediate partition board is designed, the thickness of a multi-layer corrugated box board is saved, the air bag rods arranged between the upper layer and the lower layer or between the multi-layer corrugated box board and the multi-layer corrugated box board are mutually extruded when external force is generated to deform, the overall upward resultant force is generated, deformation is resisted, and the compressive strength of the whole box board is improved.

Drawings

The device of the present invention will be further explained with reference to the drawings and the embodiments.
