The cardboard passes through the bottom of even gluey steel roller 9 through the conveying of conveyer belt, and glue shifts to the cardboard from even gluey steel roller 9 to this realization carries out the work that hot glue paintd to the cardboard.

The implementation principle of the embodiment is as follows:

when the cold glue is needed to coat the glue on the paperboard, a worker utilizes the driving device to enable the mounting seat 4 to descend, the mounting seat 4 drives the cold glue scraping plate to move downwards, after the distance between the cold glue scraping plate and the glue retaining steel roller 33 reaches the thickness needed by the glue, the driving device is stopped, the glue is sprayed into the first glue injection groove through the glue spraying pipe 6, then the worker starts the driving motor 35, the driving motor 35 enables the glue retaining steel roller 33 to rotate relative to the cold glue scraping plate 41, the surface of the glue retaining steel roller 33 is limited by the cold glue scraping plate 41 in the rotating process to wrap a layer of glue layer with uniform thickness, and when the paperboard passes through the bottom of the glue retaining steel roller 33, the glue retaining steel roller 33 coats the glue on the surface of the paperboard so as to coat the cold glue on the paperboard.

When the hot glue is needed to coat the glue on the paperboard, the worker jacks the glue remaining steel roller 33 by a certain height by using the jacking oil cylinder 31, then lifts the cold glue scraper blade 41 by using the driving device, and the supporting seat 71 pushes the glue rubber roller 8 to be attached to the glue remaining steel roller 33 under the matching of the feeding device. Glue enters a glue groove between the viscose rubber roller 8 and the glue steel roller 33 through the glue spraying pipe 6, at the moment, the worker leads in heat conduction oil towards the inner mandrel 32 through the heat conduction oil way 321, and the heat conduction oil heats the glue. Then the worker starts the driving motor 35, the driving motor 35 drives the glue remaining steel roller 33 to rotate, the glue remaining steel roller 33 enables the glue adhering rubber roller 8 and the glue homogenizing steel roller 9 to rotate, in the rotating process, hot glue is transferred to the surface of the glue homogenizing steel roller 9 through the glue adhering rubber roller 8, the hot glue is smeared to the surface of the paperboard when the paperboard passes through the lower surface of the glue homogenizing steel roller 9, and therefore smearing of the hot glue is achieved.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
