Alumite coating equipment

Abstract

The invention discloses alumite coating equipment. The alumite coating equipment comprises a coating outer shell, a rubber roller, a pressing roller, a driving motor, a gluing module and a coating outer shell; the rubber roller is rotationally connected with the coating outer shell; a driving gear is fixed on one side of the rubber roller; the pressing roller is positioned above the rubber roller,and is rotationally connected with the coating outer shell; a driven gear is arranged on one side of the pressing roller, and is engaged with the driving gear; the driving motor is arranged on one side of the coating outer shell; an output end of the driving motor is fixedly connected with the rubber roller; the gluing module is positioned at the bottom of the rubber roller, and is fixedly connected with the coating outer shell; through the coating module, glue in a glue tank is in a moving state, so that the uniformity of each part of the glue is guaranteed; and on the other hand, the glue on the edge of the glue tank is continuously cleaned into the glue tank, so that the glue cost is saved, the influence on coating of alumite plates by mixing of deteriorated glue with existing glue isprevented, the cleaning difficulty of the glue tank after use is reduced, and the cleaning time is shortened.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to an anodized aluminum coating equipment. Background technique [0002] Anodized aluminum foil is a hot stamping material made by coating and vacuum evaporation on a film base and adding a layer of metal foil. The thickness of anodized aluminum is generally (12, 16, 18, 20) um. 500~1500mm wide polyester film, generally 16um thick and 500mm wide film in China. [0003] Anodized aluminum foil is made by coating a release layer, an imaging layer, and embossing a laser pattern on a film sheet, after vacuum aluminum plating, then coating an adhesive layer, and finally rewinding the finished product. The domestic anodized aluminum foil generally has 4~5 layers. Most of the existing anodized aluminum coatings use a roll coater, that is, the glue is pressed on the anodized aluminum by the pressure between the rollers, but the existing anodized When coating aluminum coating equipme...

Problems solved by technology

The domestic anodized aluminum foil generally has 4~5 layers. Most of the existing anodized aluminum coatings use a roll coater, that is, the glue is pressed on the anodized aluminum by the pressure between the rollers, but the existing anodized When coating aluminum coating equipment, on the one hand, the glue is in a fixed state, and the glue is in contact with the air, especially the glue on the edge is easy to condense, so on the one hand, the glue on the edge may deteriorate and fall off, thus mixing with the glue in the glue tank. This will affect the coating quality of the overall glue. On the other hand, after the glue is condensed, more glue will be attached, which will lead to an increase in the cost of the glue, and the cleaning of the condensed glue is more difficult and laborious. Secondly, the glue in the glue tank is in the In the static state, after the glue is used for a long time on the rubber roller, it will inevitably lead to insufficient uniformity of the glue, resulting in uneven coating thickness of the anodized aluminum, which affects the processing of the anodized aluminum. Therefore, there is an urgent need for the production of an anodized aluminum coating equipment
