Technical Field

[0001] The utility model specifically relates to the field of corrugated paper, in particular to a corrugated paper gluing device. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard, and has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons, and other packaging materials for fragile goods. It is mainly made of traditional straw pulp and waste paper through pulping to make a raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

[0003] During the production and bonding process of corrugated paper, adhesive is applied to the surface of the corrugated board through a glue roller and then bonded to the corrugated board. When the width of the corrugated board is smaller than the length of the glue roller, the adhesive on the surface of the corrugated board that extends from the glue roller to the outside of the corrugated board is prone to overflow, resulting in a waste of adhesive.

[0004] For this reason, we propose a corrugated paper gluing device to solve the above problems. Utility Model Content
