Summary of the invention
This utility model provides for carrying out the dust problem that causes when teaching erases the board at present for the defect of prior art, and this utility model uses Rolling blackboard and the wiping arrangement of Electronic control, it is achieved automatic erasing, dust-proof pollution-free, time saving and energy saving function.
This utility model is for realizing object above, use following scheme: a kind of roller is from wiping dustproof blackboard, including support, the roller bearing of support both sides, be wire-wrapped on roller bearing write band and the wiping arrangement of band is write in wiping, wherein roller bearing includes actively roller bearing and driven roller bearing, and this active roller bearing passes through transmission band and is connected with the roller motor being fixed on support, cradle back is located at by described wiping arrangement, described in write band for blackboard iron sheet；Described wiping arrangement is made up of dust blowing mechanism and linear electric motors, and wherein dust blowing bar one end connects dust blowing mechanism, and its other end connects linear electric motors, and wherein dust blowing mechanism is moved back and forth in writing band by linear electric motors.
Preferably, described dust blowing mechanism includes dust blowing wiping, trace and bracing piece group, and described dust blowing is wiped in the strip being vertically arranged, and its wiping face is cotton rub or swipe, and described trace one end is wiped with dust blowing and is connected, and its other end is connected to linear electric motors；Described bracing piece group is formed fan-shaped array by multiple bodies of rod, and its opening is respectively connecting to dust blowing and wipes, and its Guan Bi end is connected to trace.
Preferably, also including control chamber and dust cover, this control chamber one end connects roller motor and linear electric motors by wire, and its other end connects attaching plug by power control switch；This dust cover cover is connected to support, roller bearing, writes outside band, roller motor and wiping arrangement and control chamber, and it is provided with opening with writing band corresponding position.
Preferably, the back bottom side of described support is provided with dust collecting installation.
Preferably, described blackboard iron sheet surface scribbles and is applicable to various writing implement high-molecular coating.
Preferably, the top, the back side of described support is equipped with parallel chute with bottom, all slides and be located in this chute in described dust scraper two ends.
Preferably, described linear electric motors are fixed on support by angle bar.
Preferably, described dust cover is additionally provided with the connector of connection wall.
The beneficial effects of the utility model: this utility model utilizes roller motor to drive roller bearing to be switched over by blackboard panel two writing surface, use wiping arrangement that the blackboard iron sheet being inverted to the back side carries out dynamically wiping repeatedly simultaneously, avoid manual wipping and contact the dust harzard that wiping brings, use the wiping arrangement being located at cradle back to utilize linear electric motors power faster reciprocal motion to prevent blackboard iron sheet from writing the unclean situation of powder wiping simultaneously；Chute is set in cradle back and keeps fit-state for spacing dust blowing mechanism with blackboard iron sheet, play more preferable wiping effect；The mode using dust cover cover to connect, prevents dust from blowing out；Application of the present utility model not only avoids manual wipping to affect respiratory health problem, more improves manipulation efficiency.

Detailed description of the invention
A kind of roller as illustrated in fig. 1-3 is from wiping dustproof blackboard, including support 1, one driven roller bearing 2 and actively roller bearing 3 are set in support 1 both sides, wherein actively roller bearing connects roller motor 4 by transmission band, this roller motor 4 is fixed on support 1, two roller bearings are wrapped with the blackboard iron sheet 5 of closed at both ends, blackboard iron sheet 5 roller motor 4 and under actively roller bearing 3 promotes front-back switch over, write condition meeting two sides；Wiping arrangement includes wiping 6 for the dust blowing of wiping writing on the blackboard, affecting the dust blowing bars 7 of dust blowing wiping 6 motion and provide the linear electric motors 8 of power for this motion, and wherein dust blowing is wiped 6 and is additionally provided with the bracing piece group 9 playing enhancing degree of stability with dust blowing bar 7；Fit with blackboard iron sheet 5 in motor process to keep dust blowing in wiping arrangement to wipe 6, be equipped with parallel chute 10 at top, support 1 back side with bottom, wipe 6 two ends with this dust blowing being and slide in chute 10, play more preferable wiping effect；In order to adapt to the practical multipurpose writing implement of blackboard iron sheet 5, scribble on its surface and be applicable to various writing implement high-molecular coating；
Holding, linear electric motors 8 are fixed on support by angle bar, and linear electric motors 8 are in support 1 back side, and leave suitable distance between blackboard iron sheet 5；
Hold, in order to be placed on body of wall by this device, therefore on support 1, be provided with connector, be used for connecting wall；
Holding, linear electric motors 8 and the roller motor 4 of this device connect control chamber 11 by wire, and control chamber 11 connects attaching plug by and off switch；
Hold, take over control dust hood 12 in whole device outside mask, it is to avoid the dust of wiping is blown out.
As follows according to said structure operating process in use:
