Abstract
The invention relates to a bidirectional-driving belt transmission self-absorption-type powder-driven blackboard eraser which comprises a board eraser, a blackboard and a power controlled device, wherein wall bodies at the left side and the right side of the blackboard are respectively provdied with a transmission device; the two transmission devices are linked and arranged on a board eraser guide device at the lower frame of the blackboard; the board eraser guide device is provided with a self-absorption-type board eraser; a dual-speed-reduction motor is adopted to bidirectionally drive a roller wheel to rotate; the roller wheel drives upper and lower thin steel strips to transmit synchronously, thus the blackboard eraser moves at the uniform speed stably; the self-absorption-type board eraser is of a suspension-type structure; uniformly distributed magnets are adhered to a thin iron plate; when the blackboard is erased, the board surface of the existing blackboard with a metal board surface can adapt to automatic leveling, the chalk traces can be erased very cleanly, and the self-absorption-type board eraser is installed through a clip, thus the board eraser is convenient to replace or clean; when the self-absorption-type board eraser operates left and right, chalk powder is mostly accumulated to two side surfaces of the board eraser, under the effect of static electricity, the chalk powder is adsorbed mutually, and when the chalk powder is accumulated to a certain quantity, the chalk powder is formed to be of a block shape, and falls off naturally, no chalk dust flies, and the problem that the powder dust pollutes environment and endangers health is solved effectively; and the bidirectional-driving belt transmission self-absorption-type powder-driven blackboard eraser is convenient to use, and is labor-saving and time-saving.
Description
Technical field
The invention belongs to the school supply and stationery field, relate to the self-priming electric blackboard eraser of a kind of bi-directional drive belt drive.
Background technology
Traditional blackboard eraser is commonly Brush type; Teacher is when erasing the board; Need hold this blackboard eraser and move around up and down and could the chalk mark on the blackboard be wiped clean, often will repeat so many times action that erases the board on the classroom, increase heavy manual labor to teacher; And use this blackboard eraser chalk dust when erasing the board to fly upward everywhere and cause air pollution, airborne dust granules is healthy very unfavorable to teacher's.Fly upward for reducing chalk dust, many teachers adopt wet cloth to erase the board, but fundamentally do not alleviate the amount of labour that teacher erases the board, and also thoroughly do not solve for hundreds of years chalk dust to the air-polluting problem.
In addition because the height of blackboard, when the middle part of blackboard write full after, teacher will owe pin usually or stretch high arm in the eminence of blackboard or bend over to continue to write at the lower of blackboard, this has increased teacher's labour intensity undoubtedly.
Summary of the invention
The object of the present invention is to provide the self-priming electric blackboard eraser of a kind of bi-directional drive belt drive, make the automation that erases the board, solve chalk dust the air-polluting problem, easy to use, laborsaving saving time, wiping effect is good.
The technical scheme that the present invention adopts: the self-priming electric blackboard eraser of a kind of bi-directional drive belt drive; Comprise blackboard eraser, blackboard and electric control gear; Transmission device respectively is installed on the body of wall of its blackboard left and right sides; Two transmission devices connect the blackboard eraser guider that is arranged on the blackboard upper and lower side frame, and the blackboard eraser guider is provided with self-priming blackboard eraser.
Described two transmission device left-right symmetric; Structure is identical, is separately positioned in the safty shield of the left and right sides, and the base plate of transmission device is fixed on the body of wall of blackboard both sides; Reducing motor, bearing and bearing block respectively are installed on the base plate of the left and right sides, and two reducing motors are respectively positive hour hands and rotate and rotate counterclockwise.
The left and right sides reducing motor output shaft of described transmission device connects left and right sides power transmission shaft through left and right sides shaft coupling; The two ends of each power transmission shaft are arranged in bearing and the bearing block; Upper side frame and corresponding two rollers up and down of lower frame with blackboard are installed on each power transmission shaft; On last bottom roller, be separately installed with up and down two thin steel bands, and thin steel band is along laying in the upper side frame of blackboard and the lower frame.
The directive wheel of described blackboard eraser guider is arranged on the upper side frame of blackboard; Be provided with bearing in the directive wheel; In the upper side frame of blackboard and lower frame, be provided with laterally zygomorphic clamp, clamp and steel band connect firmly, and the upper left corner and the upper right corner are provided with travel switch in the frame of the both sides of blackboard.
Described self-priming blackboard eraser top connects with directive wheel through packing ring, bolt and nut, and self-priming blackboard eraser is arranged in the last lower clip of blackboard eraser guider.
Be bonded with magnetic patch on the sheet iron of described self-priming blackboard eraser and place the lucite back side of panel; Press strip is pressed on the sheet iron and with plexiglass base plate and is adhesively fixed; The sheet iron periphery is bonded with fur, and the extended periphery of fur is inboard to be adhesively fixed with the lucite back side of panel.
The positive beneficial effect that the present invention had:
1. adopt two reducing motor bi-directional drive to drive roller and rotate, roller drives thin up and down steel band Synchronous Transmission simultaneously, because rotating speed is slower; About 100 rev/mins; Steel band is very thin, and it is very little that steel band is wrapped on the roller vary in diameter, so can realize that the steel strip driving blackboard eraser at the uniform velocity steadily moves up and down;
2. self-priming blackboard eraser is floated structure, on sheet iron, is bonded with the magnetic patch that is uniformly distributed with, and can adapt to the plate face Automatic Levelling of existing metal black-board when erasing the board, with the chalk mark wipe very clean, fine through the experiment wiping effect;
3. self-priming blackboard eraser is installed through clamp, is convenient for changing or cleans blackboard eraser;
4. not having chalk dust when erasing the board flies upward; Because self-priming blackboard eraser about when moving, chalk powder concentrates at two sides of blackboard eraser mostly, under the fur electrostatic interaction; Chalk powder adsorbs each other; When assembling certain quantity, will become block and come off naturally, fundamentally solved the problem of environmental pollution that dust causes;
5. electric blackboard eraser substitutes and manually erases the board; Automaticity is high; As long as with have gentle hands flicking switch once, the word on 6～7 square metres of blackboards only needed to disappear for 30 seconds, made things convenient for teacher to continue in the middle part of blackboard, to write; Need not owe pin and bend over and write, alleviate the teacher amount of labour that erases the board and the labour intensity of writing greatly with comfortable posture;
6. electric blackboard eraser is easy to use, and laborsaving saving time is pollution-free to air, avoids the healthy of dust granules infringement teacher, helps popularizing automated teaching and civilization teaching.
