In the process of the rolling shutter door 2 being rolled up into the mounting box 1, the two side surfaces of the moving rolling shutter door 2 respectively contact the felt 502 on the two groups of mounting cylinders 501, and the hard objects and impurities attached to the rolling shutter door 2 are adhered to the felt 502. At this time, the cylinder 505 is started to drive the sliding of the rack 504, and the gear 503 is cooperated to make the mounting cylinder 501 drive the felt 502 to rotate one hundred and eighty degrees in the mounting seat 3, completing the conversion of the cleaning surface of the felt 502.
[0029] In this embodiment, reference Figure 5 、 Figure 6 and Figure 7 As shown, the mounting frame 4 is provided with two sets of symmetrically distributed screw rods 602, the left ends of the two sets of screw rods 602 are sleeved with synchronous wheels 603, the mounting frame 4 is provided with a synchronous belt 604, the synchronous belt 604 is respectively connected to the two sets of synchronous wheels 603, the two ends of the two sets of screw rods 602 respectively pass through the mounting frame 4 and are rotatably connected to the mounting frame 4, the two sets of screw rods 602 are correspondingly arranged with the mobile frame 601, the two sets of screw rods 602 respectively pass through the mobile frame 601 and are connected to the mobile frame 601 The movable rod 605 is connected to the movable frame 601 by a screw thread, and two sets of symmetrically distributed slide rods 607 are provided in the movable frame 601, and the movable rod 605 is respectively slidably sleeved with the two sets of slide rods 607.
