During specific work, the cleaning brush 71 rotates along with the rotating shaft 72 through friction force between the rubber sleeve and the rotating shaft 72, after the cleaning brush 71 is long in service time, the cleaning brush 71 can be turned over through rotating the rubber sleeve, and the cleaning brush 71 is cleaned by using an external cleaning tool, so that the cleaning of the cleaning brush 71 is kept.
The method comprises the following steps of S1: when the rolling shutter door is rolled, the rolling shutter motor 61 is used for controlling the scroll 62 to rotate, the rolling shutter roller 63 is controlled to drive the door curtain leaves 1 to roll, when the door curtain leaves 1 are rolled, the supporting plate can push the U-shaped plate frames 312 at the bottommost part to move upwards and then accumulate in sequence to roll, all the U-shaped plate frames 312 can be accumulated at the upper part, when the rolling shutter door is put down, the U-shaped plate frames 312 are affected by gravity and move downwards along the guide rods 313 along the door curtain leaves 1, the positioning arc frames 321 corresponding to the heights can intercept the moving arc frames 322 on the corresponding U-shaped plate frames 312, the U-shaped plate frames 312 are correspondingly distributed at the heights at the same intervals, the door curtain leaves 1 are supported, and the door curtain leaves 1 are prevented from being deformed to be contacted with the door frames 2.
S2, in the rolling and lowering stages of the rolling door, the worm gear 751 is driven to rotate by the rotation of the rolling roller 63, the worm sleeve 752 is controlled to drive the coupler 744 to rotate, the second bevel gear 742 is controlled by the coupler 744 to drive the first bevel gear 741 and the third bevel gear 743 to rotate alternately, the rotating shaft 72 rotates positively and negatively, and the cleaning brush 71 is driven to swing reciprocally by the rotating shaft 72 to clean the moving door curtain leaves 1.
S3: at intervals, the rack 542 is controlled by the electric push rod II 541 to move so as to drive the connecting gear 543 to rotate, the connecting rod 544 drives the ball 545 to rotate, lubricating oil can be discharged when the oil outlet channel 546 is consistent with the direction of the opening, the ball 545 seals the opening when the oil outlet channel 546 is perpendicular to the direction of the opening, the lubricating oil cannot be discharged, the piston 522 is controlled by the electric push rod I521 to push the lubricating oil, so that the lubricating oil is pressed to flow out of the opening, the lubricating oil is discharged through the oil outlet pipe 55, the lubricating oil is dispersed along the oil guide groove 3131, and the connection between the U plate frame 312 and the guide rod 313 is kept smooth.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
