Technical Field

[0001] This utility model relates to the technical field of corrugated paper processing equipment, and in particular to a corrugated cardboard flattening device for corrugated paper processing. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single-wall corrugated paperboard and double-wall corrugated paperboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. More than 80% of corrugated paper can be recycled and is widely used in packaging, transportation and other industries.

[0003] During the processing of corrugated paper, due to the production process or storage method, corrugated paperboard often curls and wrinkles, which affects the subsequent processing quality and the appearance of the product. Therefore, it is necessary to flatten the corrugated paperboard.

[0004] Most existing corrugated cardboard flattening devices use upper and lower pressure rollers to flatten the corrugated cardboard. However, this flattening method has some shortcomings: on the one hand, the pressure of the pressure rollers is difficult to adjust, and it is impossible to achieve the ideal flattening effect for corrugated cardboard of different thicknesses and materials; on the other hand, the corrugated cardboard is prone to shifting during the flattening process, affecting the flattening accuracy.

[0005] Therefore, this utility model proposes a corrugated cardboard flattening device for corrugated paper processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated cardboard flattening device for corrugated paper processing.
