[0028] A coating mechanism 2 is provided at the end of the workbench 1 away from the discharging unit, and the coating mechanism 2 is used to coat the tin-plated sheet output by the winding shaft 11;

[0029] like Figure 2-Figure 3 As shown, the coating mechanism 2 includes a coating table 21 and guide rails 22 installed on both sides of the coating table 21. The coating table 21 is used to lay tin-plated sheets. A frame 23 is slidably installed on the guide rails 22. The frame 23 is suitable for sliding along the guide rails 22 under external drive, wherein the external drive can adopt a screw transmission structure or other driving methods, which are not limited here;

[0030] A slide plate 24 is slidably mounted on the frame 23, and the slide plate 24 is suitable for approaching or moving away from the coating station 21, and a coating die head 25 is fixedly mounted below the slide plate 24;

[0031] like Figure 4 As shown, a liquid nozzle 251 is fixed on the coating die 25, and the liquid nozzle 251 is connected to a pipeline, and the end of the pipeline away from the liquid nozzle 251 is connected to a barrel for holding the coating, and a pump connected to the pipeline is provided on the barrel, so that the coating is pumped out by the pump, and the coating is input into the coating die 25 through the cooperation of the pipeline and the liquid nozzle 251, and a slit 252 connected to the liquid nozzle 251 is provided at the output end of the coating die 25, and the slit 252 is used to output the coating.
