A gear 22 is arranged at one end of the transmission shaft 20, and the gear 22 meshes with a rack 8. A second motor 26 is arranged at the lower part of the moving frame 15 through a bracket. The second motor 26 is linked with the corresponding lower leveling roller 19 through a toothed belt pulley and a toothed belt. The corresponding lower leveling roller 19 is driven to rotate by the second motor 26, so as to perform auxiliary traction.

[0028] Working method and principle: After the paper is dried, it enters the coater from one end of the fixed frame 1. The upper glue supply pipe 5 and the lower glue supply pipe 6 both release glue. The glue drops from the glue dropping holes on the lower surfaces of the upper glue supply pipe 5 and the lower glue supply pipe 6, and the glue flows between the upper coating roller 11 and the upper squeegee 12, and between the lower coating roller 13 and the lower squeegee 14 respectively. The distance between the upper coating roller 11 and the upper squeegee 12, and between the lower coating roller 13 and the lower squeegee 14 is adjusted by the screw 28, so that the glue is respectively coated on the upper and lower surfaces of the paper. Then the paper is supported on the top of the lower smoothing roller 19. At this time, according to the material or performance of the paper, the height of the first lifting frame 10 is controlled by the first cylinder 9, so that the upper coating roller 11 and the lower coating roller 13 respectively press the upper and lower surfaces of the paper. The height of the second lifting frame 17 is controlled by the second cylinder 16, so that the upper smoothing roller 18 presses on the upper surface of the paper. Different papers have different pressing forces. At the same time, the corresponding lower smoothing roller 19 is driven to rotate by starting the second motor 26, so as to realize synchronous traction. During the process, through the cooperation of the upper smoothing roller 18 and the lower smoothing roller 19, the glue on the upper and lower surfaces of the paper is smoothed. At the same time, the smoothing mechanism drives the transmission shaft 20 to rotate through the cooperation of the first motor 21, so that through the cooperation of the gear 22 and the rack 8, the translation of the smoothing mechanism can be realized. For light paper, the smoothing mechanism can be farther away, and for heavier paper, the smoothing mechanism can be closer. The structure of the utility model is reasonable. The coating mechanism is installed in the fixed frame 1, and the smoothing mechanism is installed in the extension frame 2. The coating mechanism and the smoothing mechanism are installed in one frame, and the structure is more compact, saving floor space. Moreover, the upper coating roller 11 and the upper squeegee 12 can be lifted and lowered along with the first lifting frame 10, and the upper smoothing roller 18 can be lifted and lowered along with the second lifting frame 17, so that the pressure can be adjusted according to papers of different materials. At the same time, the smoothing mechanism can be horizontally moved along the transverse guide rail 7, and the distance between the smoothing mechanism and the coating structure can also be adjusted according to papers of different materials, so as to conveniently and flexibly meet the production needs, and the scope of application is greatly improved.
