Abstract

The invention relates to a novel dust-free blackboard, in particular to the novel dust-free blackboard in the field of mechatronics, the blackboard in the current market can produce a large amount of dust in a using process, labor and time are wasted in cleaning of the blackboard, and the dust pollution is produced and causes serious harm to body health of teachers and students. During the using process of the novel dust-free blackboard, the erased dust is collected in a dust box, so that the air pollution caused by dust drifting is prevented, and the blackboard can be popularized in teaching use abundantly.

Description

Novel dustless blackboard

1, technical field

The invention belongs to a kind of new type blackboard, be specifically related to a kind of dust-free blackboard of mechano-electronic field.

2, background technology

The blackboard used in the market can be divided into three major types: one, common green plate, and this blackboard is modal type, and with chalk-writing, its advantage is workable, and shortcoming is that dust pollution is serious; Two, high optic panel, this blackboard needs to coordinate water-soluble pen to write, although it overcomes the problem of dust pollution, water-soluble pen needs to buy, and high times of cost ratio chalk, improves use cost, and writing experience is not as chalk.Be difficult to accomplish to universal in a large number in the whole nation, therefore this high optic panel is only for special occasions, such as meeting room, computer classroom etc.Three, electrostatic dust prevention blackboard, this blackboard installs electrostatic dust protection device additional on green plate, and dust-proof effect is relatively good at short notice for it, but its service life is shorter, about half a year, and troublesome maintenance.Except above three kinds of blackboards, also have a kind of liquid aqueous chalk, this chalk can be write on common green plate, chalk is liquid state, writes the absorption of rear slabbing or comes off in plate face, can not produce a large amount of dust, but use cost is expensive, is not suitable for common teaching and uses.

3, summary of the invention

Technical problem to be solved by this invention does not produce dust in the process erased the board, and realizes a kind of low cost, high efficiency, dustlessization teaching.

Dust, clean blackboard is not produced in order to the present invention that solves the problem is one, comprising: plank (1), blackboard paste (2), friction cylinder (3), blackboard slot (4), motor (5), case shell (6), dust box (7), spring (8), dust arrester (9), pinion (10), middle gear (11), gear wheel (12), belt pulley A (13), belt pulley B (14), flat rubber belting (15), press button (16), screw rod (17).

Wherein: at two, the left and right of blackboard end face, a belt pulley A (13) belt pulley B (14) is installed respectively, the thickness of belt pulley is equal with the width of blackboard, belt pulley circumferentially have circular groove, each belt pulley respectively has three circular groove grooves equal with the distance between groove.Loaded by flat rubber belting (15) on belt pulley A (13) and belt pulley B (14), Fig. 5 in one plane, is seen in flat rubber belting (15) and plank (1) surface.Be posted in by annular blackboard on flat rubber belting (15) and plank (1), wherein flat rubber belting and blackboard paste and are sticked together, and blackboard subsides can be followed flat rubber belting and be rotated together, see Fig. 6.Have the cylinder (3) that rubs at the left end of blackboard, install a dust arrester (9), and surface contacts with each other along on its generatrix direction, when the cylinder (3) that rubs rotates, both will rub, and see Fig. 4.A motor (5) is installed in the lower left of blackboard, friction cylinder (3) and belt pulley A (13) main shaft are respectively installed a pinion (11) (12), pinion (10) on motor (5) engages with gear (11) (12) simultaneously, sees Fig. 2.And motor (5) is by a set of photoelectric sensor system and Single-chip Controlling, according to this cover system, different functions (as realizing which function, can be described in detail later) can be realized.Have in blackboard slot (4) groove at the lower limb of blackboard and several press buttones (16) are installed, see Fig. 4.On the right side of blackboard, inferior horn respectively installs two springs (8), it can make flat rubber belting under tension all the time, flat rubber belting (15) uses for a long time and can not loosen and cause skidding, the pulling force size of flat rubber belting (15) inside can pass through the nut realization of regulating spring (8) both sides, sees Fig. 3.

When Novel dustless blackboard works, under the driving of motor (5), friction cylinder (3) rotates clockwise, blackboard pastes (2) and also rotates clockwise, word is above transmitted to the left, when the word on blackboard subsides (2) and friction cylinder (3) surface contact, by friction, word is wiped, at this moment the cylinder (3) that rubs is surperficial just adheres to a large amount of dust, again with dust arrester (9) contact friction, just the dust on surface can be removed, drop in the dust box (7) of below.So just like a cork the word on blackboard can be wiped, can not dust be produced, and efficiency be high.Time saving and energy saving.

5, detailed description of the invention

On the case shell of Novel dustless blackboard install a switch, when blackboard is write expired word need all to wipe time, Push switch, word on blackboard subsides (2) is under the drive of belt pulley, to left movement, word and friction cylinder (3) contact friction, wipe word.Meanwhile, the blackboard that the blackboard back side is clean pastes and rotates to front, so just can continue to write on blackboard.In blackboard slot (4), install several press buttones, the distance between press button is at a distance of about 50cm.When the upper left demifacet of blackboard needs to wipe with word, and when the word of right-half plane does not need to wipe, just optionally can press certain press button on blackboard slot.Illustrate, such as, to the press button numbering on blackboard slot, need to wipe with the word on a left side if be from left to right respectively A, B, C, D, E...... B press button, and the word on right side needs to retain, and only needs to press B switch just passable; If E press button needs to wipe with the word on a left side, and the word on right side needs to retain, and only needs to press E switch and just can realize.If (wipe the word on the right side of E press button, and the word in left side needing to retain, and is do not accomplish), the function that these are different realized, all realized by the rotation of a set of photoelectric sensor system and Single-chip Controlling motor (5).
