The utility model is achieved through the following technical solutions：
A kind of roll type blackboard with automatic erasing function, including tourelle and automated cleaning dust arrester；It is described
Tourelle includes drive roll, driven roller, the conveyer belt and buncher for being paved with blackboard paper, and the buncher is through tooth
Wheel group and rotating shaft one end of the drive roll are connected, the both ends of the drive roll rotating shaft, the two of driven roller rotating shaft
End is fixed on framework through bearing；The automated cleaning dust arrester is arranged at the one or both sides of the tourelle, and
It is adjacent to the tourelle.
Preferably, the automated cleaning dust arrester includes dust arrester housing, the roll-type blackboard eraser provided with rotating shaft, the roller
Formula blackboard eraser is fixed on the dust arrester housing through bearing, and the rotating shaft of the roll-type blackboard eraser is through gear and the buncher
Gear train is connected by meshing transmission.
The drive roll, driven roller are hollow sheet metal cylinder.
The rotating speed of the buncher is 25rpm-35rpm.
Preferably, it is additionally provided with dust cover outside the dust arrester housing.
Compared with prior art, the beneficial effects of the utility model are：
1. blackboard panel is made roller by the utility model, automatic cleaning apparatus be close to Rolling blackboard side or
Both sides, the double use of blackboard area is not only realized, dust cover is additionally provided with outside automatic cleaning apparatus, realized under enclosed environment certainly
Dynamic blackboard wiping, really realizes dustlessization, effectively eliminates harm of the dust to human body；
2. the rolling of the utility model blackboard can be effectively increased usable floor area, efficiency of teaching is improved；
3. the utility model structure design is simply ingenious, manufacturing cost is low, practical, can be widely applied to each compound
School.
