Further, described dust arrester comprises annular resilient blackboard eraser, dust collection, handle and eccentric wheel, and described annular resilient blackboard eraser embeds described dust collection, and joins several radial holes of brill, forms dust collection passage; Described handle controls described eccentric wheel and rotates, and adjusts the compression degree between described annular resilient blackboard eraser and described flexible flat rubber belting.
Further, described coiler device comprises upper winding shaft, lower winding shaft, upper clutch, lower clutch, upper motor and lower motor, described upper clutch can realize the Engage and disengage of described upper winding shaft and described upper motor, described lower clutch can realize the Engage and disengage of described lower winding shaft and described lower motor, described upper winding shaft is identical with described lower winding shaft diameter, realizes synchronized rotating in same direction.
Further, described frame comprises left socle and right support, and common support described writing device, described dust arrester, described coiler device, and this mounting means is conducive to ensureing to write the stability with blackboard in dust removal process.
During a kind of campaign-styled flexible blackboard work of the utility model, can write on writing device with chalk, write writing device motion completely and by the process of dust arrester, writing is above wiped free of, and dust is absorbed.The course of work is roughly as follows: under the support of hard supporting plate, writes on flexible flat rubber belting with chalk; If desired wipe after flexible flat rubber belting writes full word, then descend clutch to connect, lower motor drives lower winding shaft to rotate, and flexible flat rubber belting moves downward and is wound up on lower winding shaft; Upper clutch disconnects, upper winding shaft and the synchronized rotating in same direction of lower winding shaft; Driving handle, eccentric wheel rotates, eccentric wheel radius of gyration major part is contacted with annular resilient blackboard eraser, promote the wiping of ring-type elastic plate mutually to compress with flexible flat rubber belting, under the effect of frictional force, the writing of flexible flat rubber belting above annular resilient blackboard eraser is wiped free of, and the dust of generation is radially inhaled into dust collection in hole; If do not need erasing after flexible flat rubber belting writes full word, drive handwheel, eccentric wheel rotates, eccentric wheel radius of gyration smaller portions are contacted with annular resilient blackboard eraser, thrust between annular resilient blackboard eraser and flexible flat rubber belting is removed, upper clutch is connected, and upper motor drives upper winding shaft to rotate, and flexible flat rubber belting moves upward and is wound up on upper winding shaft; Lower clutch disconnects, lower winding shaft and the synchronized rotating in same direction of upper winding shaft.
The beneficial effect of employing acquired by such scheme is:
1, flexible flat rubber belting motion, annular resilient blackboard eraser is fixed, and is convenient to collect dust, protection of the environment.
2, in the process that the flexible flat rubber belting of driven by motor moves, the writing on blackboard is wiped free of automatically, alleviates the workload of teacher.
As long as 3 flexible flat rubber belting long enoughs, blackboard to write space just enough large, the work erased the board can be placed on break and complete, and avoids the impact of dust collection noise, ensure that hours of instruction, improve effect of giving lessons.
