Description
Technical field
Exempt to wipe dustproof blackboard automatically the present invention relates to a kind of, belongs to teaching aid technical field.
Background technique
Blackboard be in middle and primary schools' daily teaching must teaching aid, daily teaching work in, whenever wiping plate face on
Chalk writing when, all can dust be flown upward everywhere, for a long time, certain shadow be caused to the health of academics and students
It rings.The mode for solving the problems, such as this at present is using the chalk writing in wet rag wiping plate face, although avoiding to a certain extent
The problem of dust is flown upward everywhere, but due to after using the chalk in wet rag wiping plate face, there are water stain on blackboard panel,
It is because skidding directly affects again writing of the chalk in plate face, therefore, after using the chalk in wet rag wiping plate face,
Teacher could write again after having to wait for water stain natural drying, directly affect the process of teaching；Therefore, it is necessary to its carry out
It improves.
Summary of the invention
The object of the present invention is to provide one kind the chalk writing in plate face to be wiped and be prevented automatically
Dust is flown upward everywhere, and avoid impacting the health of academics and students exempts from wiping dustproof blackboard automatically.
The technical scheme is that
A kind of to exempt to wipe dustproof blackboard automatically, it is made of assembling framework, main drive roller, driven voller, motor and blackboard body；It is special
Sign is: the side of assembling framework is equipped with main drive roller by mounting base and motor, and the other side of assembling framework passes through mounting base
Equipped with driven voller, blackboard body is housed on main drive roller and driven voller, it is mutual by transmission chain between main drive roller and driven voller
Connection.
The blackboard body is annular in shape, and blackboard body is made of plastic material.
Support plate is provided between the main drive roller and driven voller.Support plate contacts company with the inner surface of blackboard body
It connects.
The assembling framework is rectangular box shape body, and the front end and bottom of assembling framework are respectively open-like shape.
The assembling framework bottom is movably installed with dust collecting box.
The inner surface of the assembling framework backboard is equipped with wiping roller group by mounting base, and the wiping roller group has more
A spaced wiper rolls is constituted；The outer surface of each wiper rolls is enclosed with felt layers.
The driven voller bottom side is provided with breast wheel, breast wheel by auxiliary driving chain respectively with driven voller and wiping
Roller group connection.
The outer surface of the wiping roller group and blackboard body connects.
The assembling framework side is provided with power switch, and power switch is connect with power supply and motor.
The beneficial effects of the present invention are:
This exempts to wipe in dustproof blackboard use process automatically, and blackboard body turns around main drive roller and driven voller under the action of motor
Dynamic, when the plate face with writing turns at wiping roller group, the writing in plate face is wiped by wiper rolls, produced by erasing characters
Dust collected through dust collecting box, since the contact position of wiping roller group and blackboard body is in the space of relative closure, thus
It can prevent flying upward for dust；This exempts to wipe that dustproof blackboard structure is simple, practicability is good automatically, can be automatically to the letter written with chalk in plate face
Mark is wiped, and can prevent dust from flying upward everywhere, has positive meaning to the health of academics and students.

Specific embodiment
This is exempted from wiping dustproof blackboard automatically and is made of assembling framework 1, main drive roller 2, driven voller 3, motor 4 and blackboard body 5；
Assembling framework 1 is rectangular box shape body, and the front end and bottom of assembling framework 1 are respectively open-like shape.The side of assembling framework 1 passes through peace
Fill seat and motor 4 and main drive roller 2 be housed, the other side of assembling framework 1 is equipped with driven voller 3 by mounting base, main drive roller 2 and from
Blackboard body 5 is housed, blackboard body 1 is annular in shape, and blackboard body 1 is made of plastic material on dynamic roller 3.Main drive roller 2 and driven
It is connected with each other between roller 3 by transmission chain 6.
Support plate 7 is provided between main drive roller 2 and driven voller 3.Support plate 7 passes through connecting column (not shown) and assembly
The top plate of frame 1 connects；Support plate 7 is connect with the inner surface sliding contact of blackboard body 5.The purpose of setting of support plate 7 is pair
Blackboard body 5 formed support, with facilitate in plate face writing and the later period wiping 5 plate face writing of blackboard body when prevent it
Deform and can not be by writing wiped clean.
1 bottom active card of assembling framework is equipped with dust collecting box 8, for collecting chalk dust caused by wiping blackboard,
In use process, focused on after dust collection is a certain amount of.The inner surface of 1 backboard of assembling framework is equipped with wiping by mounting base
Wipe roller group.Wiping roller group is made of multiple spaced wiper rolls 9；The outer surface of each wiper rolls 9 is enclosed with felt layers.Wiping
Each wiper rolls 9 of roller group is connected by the outer surface of felt layers and blackboard body 1.
3 bottom side of driven voller is provided with breast wheel 10, breast wheel 10 by auxiliary driving chain 11 respectively with driven voller 3 and wipe
Each wiper rolls 9 for wiping roller group connects.
Automatically 1 side of assembling framework for exempting to wipe dustproof blackboard is provided with power switch 12, power switch 12 and power supply and
Motor 4 connects.
This is exempted from wiping dustproof blackboard automatically and is no different in daily teaching work with normal blackboard, and the plate face of blackboard body 5 is passed through
It can write, after plate face writing is write completely, startup power supply switch 12 drives 2 counterclockwise rotation of main drive roller under the effect of motor 4
It is dynamic, to drive driven voller 3 to rotate synchronously by transmission chain 6；And then drive blackboard body 5 around main drive roller 2 and 3 turns of driven voller
It is dynamic.During this, driven voller 3 drives each wiper rolls 9 of wiping roller group to rotate by breast wheel 10 and auxiliary driving chain 11.
Since each wiper rolls 9 of wiping roller group is connected by the outer surface of felt layers and blackboard body 1.When with word
When the plate face of mark is turned at wiping roller group, the writing in plate face is wiped by the felt layers that 9 outer surface of wiper rolls is wrapped up, and wipes word
Dust caused by mark is collected through dust collecting box 8.During erasing characters, due to wiping roller group be located at blackboard body 1 and
Between 1 backboard of assembling framework in the space of relative closure, flying upward for dust thus can be prevented, thus solves existing dust everywhere
The problem of flying upward, the health of academics and students impacted.
As blackboard body 5 is around the rotation of main drive roller 2 and driven voller 3, clean plate face is gradually turned by main drive roller 2
It moves to the front end face of assembling framework 1, can be write again in plate face.
This exempts to wipe that dustproof blackboard structure is simple, practicability is good automatically, can wipe automatically the chalk writing in plate face
It wipes, and can prevent dust from flying upward everywhere, there is positive meaning to the health of academics and students.
