After position so that roller 3 can be tightly attached to the front end face of display screen 2.
Pillar 710 is detachably connected with roller 3, and pillar 710 is close to 3 one end of roller integrally formed with backplate 711, roller 3
Both ends offer card slot 712, integrally formed with the strip 713 to match with card slot 712 on backplate 712, offer on strip 713
Threaded hole 714, the via hole 715 to match with threaded hole 73 is offered on roller 3, and via hole 715 is stepped hole.It is long-term in roller 3
It using, after cleaning cotton failure, can be removed from pillar 710 together with roller 3, replacement is wound with the roller 3 of new cleaning cotton,
Fixing screws are installed fixed in via hole 715 again, replace more convenient.
The first mounting rack 8 and the second mounting rack 80 are also equipped in shell 1, motor 410 is mounted on the first mounting rack 8,
First mounting rack 8 is located remotely from 42 one end of driven sprocket, is equipped with support shaft on the second mounting rack 80, support shaft is threaded through driven
In sprocket wheel 42, the second mounting rack 80 is located remotely from 41 one end of drive sprocket.First mounting rack 8 and the second mounting rack 80 are located at
The both ends of drive sprocket 41 and driven sprocket 42 can avoid impacting the operating of mobile mechanism.
In the present embodiment, when clearing up display screen 2, motor 410 drives drive sprocket 41 to rotate counterclockwise, to drive transmission
Chain rotates counterclockwise, and when pushing block 433 is located at 42 lower section of drive sprocket 41 and driven sprocket, pushing block 433 is in transmission chain
It is moved from left to right under drive, and then the card for being located at 5 lower part of movable plate is pushed to set block 51, movable plate 5 and cross bar 55 from left to right
Movement, i.e. drive roller 3 moves to right from 2 left side of display screen, simultaneously as be provided with gear 6 on roller 3, and shell 1 in
6 front end of gear is equipped with the rack gear 61 being meshed with gear 6, and roller 3 rotates clockwise in motion process from left to right
(viewed from above), at this point, roller 3 cleans display screen 2 to friction is generated between display screen 2；
When movable plate 5 moves to right side, and skewback 52 is touched with the mandril 53 for being located at 41 lower section of drive sprocket, skewback
52 under the pushing of mandril 53, rotation counterclockwise occurs around the through-hole where articulated shaft 50, and then card is driven to set 51 inverse time of block
Needle rotation, so that being detached between fixture block 510 and pushing block 4330, i.e., transmission chain, which continues rotation, can not drive movable plate 5 mobile,
At this point, roller 3 is parked in display screen right end, mobile and rotation no longer occurs；
Drive sprocket 41 continues to rotate counterclockwise under the drive of motor 410, and card sets block 51 and moves below drive sprocket 41
Move to after top, card sets block 51 and moves from right to left, sets block 51 with the card for being located at 5 top of movable plate and contacts, drive movable plate 5 from
Dextrad left movement repeats above-mentioned scouring process, until touching the mandril 53 above driven sprocket 42, movable plate 5 is parked in
2 left end of display screen.
