NOVELTY - The utility model claims a coating device for graphene electric heating coating, belonging to the coating device. It comprises two parts of basic component and scraping component. wherein the scraping assembly comprises: a rotary screen roller rotatably mounted on the base assembly, a cutter holder located on the central axis of the rotary screen roller, a feeding pipe fixedly mounted on the cutter holder, a magnetic metal roller placed at the bottom of the rotary screen roller, an electromagnet fixedly mounted on the bottom of the transmission platform through a bracket, and a magnetic metal roller attached to the magnetic metal roller; and a limiting plate capable of lifting and installed on the cutter holder. The utility model controls the extrusion amount of the coating by adjusting the gap between the limiting plate and the rotary screen roller, by designing the distribution of the mesh of the rotary screen roller, controlling the shape of the coating extrusion, coating on the foaming ceramic, forming coating process with different thickness and pattern. The invention solves the problem that the thickness shape of the product in the coating graphene electric heating coating process of the existing coating device, the problem of single pattern.
