It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] like Figure 1 straight Figure 4As shown, a rotary dual-purpose coating knife includes a support frame 1, a driving roller 4 is rotatably connected to the middle part of the support frame 1, a knife roller 10 is arranged above the driving roller 4, and a straight scraper 14 and a comma scraper 15 are fixedly connected to the side wall of the knife roller 10. The arrangement of the straight scraper 14 and the comma scraper 15 meets the needs of different coating processes.

[0017] The upper end of the support frame 1 is vertically slidably connected to a lifting block 6, and the end of the knife roller 10 is rotatably engaged on the lifting block 6. When the lifting block 6 moves, the height of the knife roller 10 is changed. A second motor 7 is arranged on the lifting block 6, and the output end of the second motor 7 is fixedly connected to the end of the knife roller 10. When the second motor 7 is started, the knife roller 10 is driven to rotate, thereby replacing the scraper.
