Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard production, in particular to a corrugated paper gluing mechanism. Background Art

[0002] When producing corrugated cardboard, glue must first be applied to one outer surface of the corrugated paper, and the corrugated paper coated with glue is then laminated to the base paper to form a semi-finished corrugated cardboard. Then glue is applied to the other outer surface of the corrugated paper in the semi-finished corrugated cardboard, and the semi-finished corrugated cardboard coated with glue is again laminated to the base paper to form a corrugated cardboard.

[0003] During the first glue application, the glue roller rotates and picks up the glue in the placement tank at the same time. The glue roller with glue on its surface contacts one of the outer surfaces of the continuously moving corrugated paper and transfers the glue to the corrugated paper. Since the glue is made of a mixture of water, starch, caustic soda, etc., the glue will be stratified if it is not stirred for a long time, which will weaken the viscosity of the upper glue layer, thereby causing the adhesion quality of the corrugated paper to the base paper to deteriorate. The existing method usually provides a stirring rod in the placement tank to solve the problem of stratification caused by the glue being left stationary for a long time. However, the existing stirring rod is usually close to the bottom of the placement tank and can only stir the glue below the glue roller, but cannot stir the upper glue in contact with the glue roller. The glue cannot be fully stirred, so that the upper glue and the lower glue cannot be fully mixed, and the viscosity of the glue cannot be effectively improved to improve the adhesion quality. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide a corrugated paper gluing mechanism that can fully stir the glue so that the upper layer of glue and the lower layer of glue are fully mixed, effectively improving the viscosity of the glue, thereby improving the gluing quality of the corrugated cardboard.

[0005] The technical solution adopted by the present utility model is as follows: a corrugated paper gluing mechanism, comprising a placement trough for placing glue, a glue-dipping roller for dipping glue is provided above the placement trough, a first stirring component for stirring glue is provided in the placement trough, the first stirring component comprises a first rotating shaft, and a plurality of first stirring members located on the first rotating shaft, the projections of the glue-dipping roller and the first rotating shaft projected on the bottom of the placement trough are staggered, an elastic stirring sheet is provided at one end of the first stirring member away from the first rotating shaft, the stirring sheet can be located above the glue liquid surface or in contact with the bottom of the placement trough, and the stirring sheet is away from the glue-dipping roller.

[0006] Principle of the technical solution:

[0007] Since the stirring blade is elastic and can be located above the glue liquid surface or in contact with the bottom of the placement tank, when the first rotating shaft rotates, the first rotating shaft drives the stirring blade to rotate. When the stirring blade rotates, it drives the upper layer of glue to flow vertically and circumferentially to the lower layer and mix with the lower layer of glue. At the same time, it also drives the lower layer of glue to flow vertically and circumferentially to the upper layer and mix with the upper layer of glue, so that the upper layer of glue and the lower layer of glue are fully mixed. Since the projections of the glue-dipping roller and the first rotating shaft on the bottom of the placement tank are staggered, and the stirring blade is away from the glue-dipping roller, stirring and gluing can be carried out simultaneously.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Beneficial effect: The stirring blade is elastic and bends when it contacts the bottom of the placement groove. The surface of the stirring blade contacts the bottom of the placement groove. When the stirring blade rotates, the stirring blade slides across the bottom of the placement groove and scrapes away the glue at the bottom of the placement groove, which can improve the stirring effect.

[0012] As a preferred embodiment of the present invention, multiple first stirring members are arranged radially along the first rotating shaft, and each first stirring member includes multiple circumferentially arranged first stirring blades, and the end of the first stirring blade away from the first rotating shaft is connected to the stirring sheet.

[0013] Beneficial effect: The multiple first stirring blades can increase the contact surface with the glue and can fully stir the glue.

[0015] Beneficial effect: The glue below the glue-dipping roller can be fully stirred, and the glue in the placement tank can be fully stirred in cooperation with the first stirring component, thereby improving the stirring efficiency.

[0016] As a preferred embodiment of the present invention, a scraper assembly for scraping excess glue on the glue roller is provided above the placement groove. The scraper assembly includes a fixed shaft and a scraper blade. One end of the scraper blade is connected to the fixed shaft, and the inner surface of the other end is in contact with the outer surface of the glue roller.

[0017] Beneficial effect: After the glue roller is dipped in glue, in addition to the glue on the surface of the glue roller, excess glue will be carried out of the placement groove through the glue on the surface of the glue roller, and the scraper can scrape off the excess glue.

[0018] As a preferred embodiment of the present invention, the place where the glue-dipping roller and the scraper blade are in contact is located above the placement groove.

[0019] Beneficial effect: The scraped glue can be directly returned to the placement groove without the need for additional components for holding the glue.

[0020] As a preferred embodiment of the present invention, a gluing roller for gluing corrugated paper is provided on the gluing roller, and the outer surface of the gluing roller is in contact with the outer surface of the gluing roller and both of them rotate.

[0021] Beneficial effect: The glue coating roller can be evenly stained with glue, the corrugated paper can be evenly coated with glue, and the gluing quality can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
