step (3), the rotating disc 28 can be driven to rotate by the motor 27 in the first brushing structure 2, and the sleeve rod on the rotating disc 28 is movably connected with the swinging frame 22, so that eccentric rotation of the sleeve rod can be realized, and the swinging frame 22 can be forced to swing in the fixed frame 21 in a left-right reciprocating manner; the scraping strips 26 positioned on the upper side and the lower side of the diaphragm are contacted, so that the residual is scraped off on a large scale by the upper side wall and the lower side wall of the diaphragm, and the water in the first box 11 is stirred to be fully contacted; meanwhile, the air pump 16 at the front side of the first box body 11 is controlled to drive the air pump to blow out through the air holes of the scraping arm 25, so that a large amount of bubbles are generated, the liquid at the upper side and the lower side of the diaphragm is stirred again, the bubbles float upwards, and the removal of residual liquid is promoted;
step (4), the diaphragm can be contacted with water again for a long time through the guide structure 4, the contact and the rinsing are carried out relative to the stationary water through the movement of the diaphragm, and the retention time of the diaphragm in the second box body 12 can be adjusted by adjusting the distance between the two guide rollers 424 on the guide assembly 42;
step (5), finally, the second brushing structure 3 is driven the same as the first brushing structure 2, so that the left-and-right swing of the horizontal part of the diaphragm is realized to scrape larger residual water drops, the part of the diaphragm, which scrapes the water drops, is quickly air-dried by blowing, and then reciprocates, so that the effect of quick drying is realized (note that in order to improve the cleaning effect, the diaphragm does not move too fast, but the swinging speed of the scraping arm 25 is greater than the moving speed of the diaphragm, so that the repeated scraping and air-drying of one part can be realized);
and (6) rotating the first adjusting screw 23 according to the thickness of the diaphragm to enable the first sliding seat 24 to be stressed to relatively move or move in opposite directions, and adjusting the distance between the two scraping arms 25, namely adjusting the distance between the scraping strips 26 to enable the scraping strips 26 to be attached to the upper side surface and the lower side surface of the diaphragm.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
