Description
Technical field
The utility model relates to a kind of abrasive tumbling formula driven blackboard device.
Background technology
In school and constituent parts, generally use at present the fixing old-fashioned blackboard of manually wiping, this blackboard wipe a large amount of dust of middle generation, damage to user's health.Show according to survey data: the sick rate of teaching profession is the trend rising year by year, the pneumoconiosis that wherein dust causes and various acute and chronic breathing problem are main in the current occupational disease of China, harm is the most serious and the most a kind of, the questionnaire sample investigation result of in nineteen ninety-five, 3125 teachers in primary and middle schools of 30Suo middle school, Foochow and 6 primary schools being carried out as education expert Tian Jun shows: teachers in primary and middle schools' respiratory system Prevalence Rate of Chronic Diseases is higher, common is chronic pharyngitis and vocal cords disease, wherein male sex's Prevalence Rate of Chronic Diseases is 58.53%, the chronic illness rate of women is 61.06%, and all have with the length of teaching increasing the trend raising.
Meanwhile, the process that old-fashioned blackboard eraser removes, also wastes a lot of time, and class 45 minutes, on average wiped a blackboard with 3 minutes, and every class is wiped 3 blackboards, five/once time be wasted in and erased the board on.
Prior art solves the problem of chalk dust by the blackboard eraser of motion, blackboard is special but not common fixing blackboard on the wall.Blackboard eraser is enclosed within on blackboard and fixes.Therefore the thickness of blackboard has certain control.Blackboard eraser is attached to blackboard surface, by movement, removes writing by hairbrush, and the dust of generation is absorbed by inner dust catcher.Just because of adopting blackboard eraser to move and the static mode of blackboard, cause blackboard eraser to be easy to loosening distortion, and the dust of accumulation can not be removed in time, also caused obstruction, and then aggravate distortion, although this mode, having solved to a certain extent the disorderly problem of chalk dust, aspect waste settling time, does not have the solution of essence.Still need the process of waiting for that blackboard eraser removes, need to wait for that blackboard eraser is from clipping another side on one side.Meanwhile, adopt that blackboard eraser is moving and the static mode of blackboard causes the wearing and tearing of blackboard eraser very serious, easily deform.The replacement cost of blackboard eraser is higher simultaneously, has lost economic worth, is not also therefore promoted on a large scale, and occupation rate of market is very low.
Existing scheme cannot realize absolute dustlessization, and wipes because it adopts the friction of blackboard eraser and blackboard to realize, and noise is large and dust is disorderly.Even if damage to user's health, but in cleaning blackboard, still can produce dust, if cleaning personnel wear special protective garment, caused cost rising.

The utility model solves the technical scheme that its technical problem adopts: a kind of abrasive tumbling formula driven blackboard device, have and be arranged on same fixed support and the moving cylinder of the principal and subordinate who is oppositely arranged and secondary driven cylinder, between the moving cylinder of described principal and subordinate and secondary driven cylinder, be provided with fixed dam, move the upper of cylinder and secondary driven cylinder described principal and subordinate, lower two ends are equipped with turntable bearing, move the upper of cylinder described principal and subordinate, lower two ends are equipped with synchronizing wheel driven by stepper motors, be provided with ring-shaped P VC substrate around the both sides, front and back of described fixed dam, outside at described ring-shaped P VC substrate is bonded with blackboard foil, upper in the inner side of described ring-shaped P VC substrate, lower two ends are equipped with the driving-belt with synchronizing wheel pairing, before the moving cylinder of described principal and subordinate, rear both sides are respectively equipped with the first rubbing frame and the second rubbing frame, be provided with the 3rd rubbing frame in the front side of the driven cylinder of described pair, and the side at described the second rubbing frame is provided with storage tank, between described storage tank and the second rubbing frame, be provided with in turn some outlet pipes from top to bottom.
Further, in order to simplify structure and as a kind of concrete version, stepper motor described in the utility model is arranged in the moving cylinder bore of principal and subordinate and is in transmission connection by decelerator and synchronizing wheel.
Further, consider that principal and subordinate moves cylinder the mechanism such as stepper motor and decelerator need to be installed, can cause differing with the diameter of secondary driven cylinder, thereby can affect the plane laminating degree of ring-shaped P VC substrate, the utility model is provided with position-limiting drum at the moving cylinder side of described principal and subordinate.
Further, in order to make the moistening region of current more even, the quantity of outlet pipe described in the utility model is 6.
Further, the friction of considering cylinder and PVC substrate produces larger resistance, in order to make cylinder along with PVC substrate motion is to reduce resistance, the upper/lower terminal of the moving cylinder of principal and subordinate described in the utility model and secondary driven cylinder is fixed on the outer ring of turntable bearing, and the inner ring of described turntable bearing is arranged on fixed support.
Further, in order to make the operation of driving-belt more solid and reliable, the utility model is equipped with the annular groove for holding driving-belt at the upper/lower terminal of the driven cylinder of described pair.
The beneficial effects of the utility model are: the utility model has solved a lot of problems existing in blackboard-cleaning, solve by introduce moistening rubbing frame in erase process the sordid problem of dust wiping erasing the board in process, also solved the situation that dust large area is piled up simultaneously, rubbing frame is easy to remove and install, can often clean, the utility model Expected Results reaches without large area dust and occurs, only produce certain dust at first rubbing frame place, can be regularly by simply rubbing frame once being cleared up without professional ability personnel, move and the motionless mode of blackboard eraser has solved the situation of the easy aging distortion of blackboard eraser by blackboard, also reduced the cost of working service simultaneously, existing electric blackboard eraser adopts common blackboard, therefore can produce huge noise, and the PVC substrate that the present invention adopts coordinates bonding blackboard foil, the sound that only exists stepper motor to rotate in rotation and erase process and to produce.
