Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing and forming, and in particular to a corrugated paper glue-free flattening and forming device. Background Art

[0002] Because corrugated paper has many advantages such as low production cost, light weight, and high compressive strength, it is often used when packaging products. In addition, waste corrugated paper is recyclable and is an environmentally friendly packaging material.

[0003] The corrugated paper 9 includes a first surface layer 91, a flat tube liner 92 and a second surface layer 93, which are stacked in sequence. The flat tube liner 92 is coated with glue on both sides, and the first surface layer 91 and the second surface layer 93 are respectively adhered. After the flat tube liner 92 is glued by the gluing machine, the flat tube liner 92 is coated with glue on both sides, and there is also glue on the side edges. After entering the double-sided machine for bonding, the glue on the side edges will overflow from both sides of the cardboard. When the cardboard is conveyed, part of the glue overflowing from the edge will adhere to the working surface of the conveyor belt and the hot plate, and the bonded glue will condense into small pieces. When the produced cardboard passes through these small uneven pieces, the surface paper will be scratched, or the bottom paper will have pits. The glue bonded to the conveyor belt will accelerate the wear and damage of the conveyor belt. If the glue is bonded to the surface of the roller, it will cause the conveyor belt to deviate and accelerate the wear of the conveyor belt. If glue can be prevented from oozing out over the edges of the board, the service life of hot plates, conveyor belts, rollers, etc. can be extended. Summary of the invention
