▎ 摘　　要

NOVELTY - Coating device comprises working chamber (1), and feeding roller (2) rotatably attached at the bottom end of one side between the inner walls of two ends of the working chamber. The inner wall of two ends of the working chamber far away from one side of the feeding roller is rotatably attached with a discharging roller (20). The position between the inner walls of two ends of the working chamber between the feeding roller and the discharging roller is rotatably attached with two pressing tubes (3). Two pressing pipes are respectively provided into a first pipe piece and a second pipe piece. The first pipe piece is located at one side close to the discharging roller, and the second pipe piece is located at one side close to the feeding roller. The first pipe piece is provided below the second pipe piece. The inner wall of two ends of the working chamber is located between the feeding roller and first pipe piece. USE - The coating device is used for processing graphene modified fiber. ADVANTAGE - The device condenses the surface of the fiber fabric; when the graphene material is sprayed to the condensing surface, the temperature difference is quickly condensed; and the graphene material is diffused towards the other surface with low temperature; and it can effectively avoid falling, so as to improve the coating effect in the actual processing operation process. DETAILED DESCRIPTION - Coating device comprises working chamber (1), and feeding roller (2) rotatably connected at the bottom end of one side between the inner walls of two ends of the working chamber. The inner wall of two ends of the working chamber far away from one side of the feeding roller is rotatably connected with a discharging roller (20). The position between the inner walls of two ends of the working chamber between the feeding roller and the discharging roller is rotatably connected with two pressing tubes (3). Two pressing pipes are respectively set into a first pipe piece and a second pipe piece. The first pipe piece is located at one side close to the discharging roller. The second pipe piece is located at one side close to the feeding roller. The first pipe piece is located below the second pipe piece. The inner wall of two ends of the working chamber is located between the feeding roller and first pipe piece, and the position between the first pipe piece and second pipe piece is fixed with a connecting pipe (4). The bottom of the outer wall of the connecting pipe is fixed with nozzles. The middle position of the feeding roller is provided with an air cavity, which is circulated with cold air. One side of the inner wall of the two ends of the working chamber located in the first pipe piece far away from the nozzle is rotatably connected with a limiting pipe, which is circulated with cold air. Two of the pressing pipes are circulated with hot air. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of coating device.
