Description
Technical field
The utility model is related to a kind of blackboard eraser, and in particular to a kind of automatic dust-absorption eraser, and automatic dust-absorption eraser is
The indispensable instrument of teaching, can rapidly and efficiently clean blackboard, mitigate the burden of academics and students, while dust can be absorbed, reduce
Harm of the dust to academics and students.
Background technology
When teacher or student are erased the board using traditional blackboard, not only compared with tired but also efficiency is low, in addition, chalk bits are diffused into
In air, the body of academics and students can be caused harm.Although occurring in that dust-free chalk currently on the market, process is used
In, one layer of chalk bits can be left on blackboard.Dust absorption blackboard eraser is also occurred in that currently on the market, but it is relatively costly, and effect is failed to understand
Aobvious, reliability is poor.
Utility model content
The purpose of this utility model is the defect for overcoming existing blackboard eraser, devises a kind of automatic dust-absorption eraser, can
Automatic blackboard cleaning is realized, and reaches the effect of dust suction.
The technical solution of the utility model is：
A kind of automatic dust-absorption eraser, including spindle motor 1, leading screw 2, guide rail 3, Rolling motor 4, wall 5, travel switch

Fast device 15, voltage raising and reducing module 16, roll left cylinder 17, right roller 18, supporting plate 19, little gear 20, left gear wheel 21, right gear wheel
22.Spindle motor 1 drives leading screw 2 to rotate, and drives blackboard eraser main body to move left and right by guide rail 3 and wheel 9, and Rolling motor 4 leads to
Cross gear drive to realize rolling left the rotating backward of cylinder 17 and right roller 18, so that a left side for realize rolling left cylinder 17 and right roller 18
Move right and rotate, strengthen wiping effect, travel switch 6 and A.C. contactor 12 can realize automatically controlling for blackboard eraser, when black
Blackboard eraser main body moves to opposite side from the side of blackboard 7, bumps against travel switch 6, and it will be automatically stopped, then press starting switch
13, it will be moved backward, and speed regulator 15 can control the speed that blackboard eraser main body is moved left and right, can be adjusted according to actual conditions
Section, the length of roll left cylinder 17 and right roller 18 is suitable with the width of blackboard 7, can disposably wipe clean blackboard 7, raising efficiency,
Roll left cylinder 17 and right roller 18 lower section equipped with dust absorption fan 10, can be by dust absorbing to dust-collecting box 11, above-mentioned each part is all
It is fixed on wall 5, need to be only improved on the basis of existing blackboard.
The utility model has the advantages that automatic blackboard cleaning can be realized, and disposably blackboard is wiped clean, efficiency high, and
And dust can be absorbed, reduce harm of the dust to academics and students.
