The rotary shutter 5 comprises a connecting rod 15 fixedly connected to the rotary shaft 14, a shutter 16 is fixedly mounted on the other end of the connecting rod 15, and an elastic sealing member 17 is mounted on the shutter 16. A driving pulley 18 is mounted on the output shaft of the rotary drive member 12, a driven pulley 19 is fixedly mounted on the rotary shaft 14, and the driving pulley 18 and the driven pulley 19 are connected by a belt 20.
