Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a cardboard gluing device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. In order to improve the overall strength of corrugated cardboard, multiple layers of corrugated cardboard need to be laminated. Conventional corrugated cardboard lamination usually uses gluing to achieve the bonding of corrugated cardboard. Existing corrugated cardboard gluing devices can usually only glue one side of the corrugated cardboard and are not adjustable enough to adapt to corrugated cardboard of various specifications. Publication number CN107984808B relates to a corrugated cardboard gluing device. The upper and lower partitions have through-holes each containing an electrically controlled valve. A stirring paddle is installed in the glue storage chamber for stirring the material, which is drivably connected to the output shaft of a first motor. The glue storage chamber is also equipped with a heating device for heating the material. The lower surface of the corrugated paper in the upper gluing chamber contacts the upper gluing roller, while the lower surface of the lining paper in the lower gluing chamber contacts the lower gluing roller. The lower gluing chamber is also connected to the glue storage chamber via a lift pump. This device cannot gluing corrugated cardboard of varying specifications and has limited adjustability.
