Abstract
An electrically controlled multifunctional blackboard which can goes up and down electrically with board writing erased automatically is provided. The blackboard adopts a driving structural style; a belt wheel motor, a transmission belt and a belt wheel are connected in turn and are fixed on a bracket of the blackboard; the transmission belt serves as the blackboard. The belt wheel motor drives the transmission belt (blackboard) to drive through the belt wheel so as to realize that the blackboard goes up and down electrically. In the front of the transmission belt, a pressing stick is hung on the bracket of the blackboard through a stick spring; the inner surface of the transmission belt near the writing side is lined with a back plate; the pressing stick causes the transmission belt to be pressed on the back plate under the elastic force of the stick spring to ensure the writing strength of a flexible blackboard. In the back of the blackboard, a brush, a main shaft of the brush and a brush motor are connected in turn to be arranged on the bracket of the blackboard; the brush motor drives the main shaft of the brush and the brush to rotate to realize automatic erasure of the board writing. A sink is arranged just below the brush to realize powder recovery.
Description
1, affiliated technical field
The utility model relates to a kind of blackboard device that can realize automatic lifting, wipe and have environment-friendly function.
2, background technology
As everyone knows, at present most blackboards is divided into wall-hanging and fixed two kinds, these blackboards have used decades continuously, the teacher needs frequent turnover blackboard, wiping examination blackboard at school the time, this not only wants physical exertion, also pollute the environment, influence attractive in appearance owing to writing a large amount of chalk dusts that produce in addition, human body sucks chalk dust for a long time and also can impair one's health.
3, summary of the invention
Drawback for aspects such as overcoming effort, trouble, contaminated environment that existing blackboard in use exists, impair one's health, the utility model provides a kind of electric-controlled type multi-functional blackboard, and this blackboard not only has automatic upset, the function of wiping automatically, also has an environment-friendly function that reduces the chalk dust escaped quantity.
The technical solution adopted in the utility model is: this electric-controlled type multi-functional blackboard, mainly by belt wheel motor, shaft coupling, belt wheel, belt wheel main shaft, driving-belt, block bearing, blackboard support, rack pin shaft, support plate, compress parts such as rod, rod spring, hairbrush, hairbrush main shaft, hairbrush motor and tank and form, wherein belt wheel motor, shaft coupling, belt wheel main shaft, belt wheel, driving-belt, block bearing are linked in sequence and form a belt driver and be installed on the blackboard support; In the front of driving-belt, compress rod, rod spring and be linked in sequence and form a hold down gag and articulate on the rack pin shaft on the blackboard support; At the back side of driving-belt, hairbrush, hairbrush main shaft and hairbrush motor are linked in sequence and form a blackboard writing erasing apparatus and be installed on the blackboard support; By the inner surface of writing side one support plate is set at driving-belt, support plate is consolidated on the blackboard support with the height that is appropriate to human body and writes; One tank is set under hairbrush, and tank is placed on the blackboard support.The material of driving-belt adopts soft rubber etc., and is coated with the last layer blackboard paint on its surface.When automatically controlled belt wheel motor opens, the stopping time, driving-belt (blackboard) also can rise at any time, stop, and can guarantee that so not only the teacher writes at suitable height, and is convenient to show.Be suitable for human body write the height the blackboard zone support plate is set, be to write hardness in order to increase.When needs were write, driving-belt was in inactive state, compressed the elastic force effect of rod by the rod spring and was pressed on the driving-belt, and driving-belt is contacted with support plate, had solved because of the soft problem that is difficult for writing of writing surface.When driving-belt is under the rotary state,, make driving-belt can not contact and cause wearing and tearing with support plate at transmission process because the effect of moment compresses rod and separate with driving-belt.Contact position linear velocity direction is opposite with the width of driving-belt is equal for the width of driving-belt back side hairbrush, when driving-belt rotates, starts the hairbrush motor hairbrush rotation can be wiped the writing on the driving-belt rapidly.Because belt wheel and hairbrush be respectively by different Electric Machine Control, do writing on the blackboard and demonstrate and do not wipe writing so also can only rotate belt wheel.Tank is set below hairbrush, the chalk dust of wiping is collected at this, be beneficial to environmental protection.
Characteristics of the present utility model are: realize blackboard automatic upset and the automatic removing of writing, reduced dust pollution, and apparatus structure is simple, be convenient to mounting or dismounting and safeguard.

5, the specific embodiment
In Fig. 1, driving-belt (8) is wound on the belt wheel (4), and belt wheel (4) is installed on the block bearing (6) by belt wheel main shaft (3), and belt wheel main shaft (3) links by shaft coupling (2) and belt wheel motor (1), when belt wheel motor (1) when starting, will drive the rotation of driving-belt (8).Driving-belt in the utility model (8) is blackboard panel, like this can by control belt wheel motor (1) open and close control blackboard panel liter, stop.Blackboard writing erasing apparatus is by hairbrush motor (14), hairbrush main shaft (15) and hairbrush (16) are formed, whole device is installed on the blackboard support (7) and is positioned at driving-belt (8) back side, open hairbrush motor (14) during use, hairbrush (16) will be driven by hairbrush main shaft (15) and rotate, thereby wipe the handwriting on the driving-belt (8).
In embodiment illustrated in fig. 2, support plate (13) pad is at the inner surface of driving-belt (8), and is consolidated on the blackboard support (7) to be appropriate to the height that human body writes, and writes hardness with increase.Support plate width (B), highly (H) for writing the zone.
In the embodiment shown in fig. 3, belt pressing device is by compressing rod (9) and rod spring (10) is formed.One end of rod spring (10) is affixed with the end face that compresses rod (9) during installation, and the rack pin shaft (11) on the other end and the blackboard support (7) articulates, and whole hold down gag can rotate around rack pin shaft (11), and guarantees that rod spring (10) is in extended state.When blackboard is in the state of writing, promptly driving-belt (8) compresses rod (9) and is subjected to the effect of rod spring (10) spring tension to produce a thrust (F to driving-belt (8) when remaining static
y), this thrust (F
y) driving-belt (8) and support plate (13) are contacted with each other, so convenient writing on soft driving-belt (8).
In the embodiment shown in fig. 4, when blackboard surface is in rollover states, promptly driving-belt (8) direction of motion (v) upwards the time, knows that by the friction force analysis driving-belt (8) will be to compressing (9) frictional force (F that make progress of rod
m), this frictional force (F
m) make the direction of rotation (ω of whole hold down gag around rack pin shaft (11)
g) upwards, driving-belt (8) leaves the surface of support plate (13) like this, when having avoided driving-belt (8) rotation and the fretting wear between support plate (13), zone face leaves the spacing of support plate (13) can be by the rigidity adjustment of rod spring (10).
In embodiment illustrated in fig. 5, the direction of rotation (ω of hairbrush (16)
s) with the direction of motion of driving-belt (8) (v) opposite, guarantee the efficient of wiping chalk writing.Because the chalk dust (18) when wiping is positioned at the back side of driving-belt (8), so reduced the escaped quantity of chalk dust (18), the chalk dust of wiping simultaneously (18) is collected by the tank (5) that is placed on blackboard device below, satisfies environmental requirement.
The utility model both can be fixed in the wall and use, also portable, at this moment the bottom size of easel (7) should suitably strengthen, to increase stability.
