Problems solved by technology
[0008] Aiming at the deficiencies of the prior art, the present invention provides a single-pit kraft corrugated cardboard with cushioning support and its special equipment, which solves the problem that the existing single-pit corrugated cardboard is easily deformed or even broken when it is squeezed by an external force, and the side wall is not made. The sealing and waterproof treatment reduces the compression and deformation resistance of the cardboard itself, and at the same time, the buffer support components are manually bonded and assembled with the cardboard, which reduces the production efficiency and assembly quality of the cardboard

The invention discloses a buffering and supporting single-pit kraft corrugated board. The kraft corrugated board comprises surface paper, bottom paper and core paper, a buffering and supporting assembly is bonded between the facing sides of the surface paper and the bottom paper through a bonding agent, and waterproof assemblies are bonded to the two sides of the surface paper and the bottom paperthrough the bonding agent; and the buffering and supporting assembly comprises an upper elastic buffer piece and a lower elastic buffer piece, and the bottom of the upper elastic buffer piece is bonded with the top of the core paper through the bonding agent. The invention relates to the technical field of kraft corrugated board production. The buffering and supporting assembly is arranged on thesingle-pit corrugated board, so the corrugated board is effectively supported, and the buffering and damping effects are achieved; and the waterproof assemblies arranged on the side walls can preventliquid from entering the interior of the corrugated board through the side walls to soak the corrugated board to influence the supporting performance of the corrugated board, meanwhile, and the corrugated board is made of kraft paper, so the deformation resistance and the waterproof performance of the corrugated board are improved.
Description
technical field [0001] The invention relates to the technical field of corrugated cardboard production, in particular to a cushioning and supporting single pit kraft corrugated cardboard and special equipment thereof. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"), it has high mechanical strength, can withstand the collision and fall during handling, the actual performance of corrugated boxes depends on three factors: core paper And the characteristics of cardboard and the structure of the carton itself are mainly used to make cartons, the sandwich of cartons and other packaging materials for fragile goods. [0003] Refer to the Chinese Patent Publication No. CN110450469A for a cushioning...
