Abstract
The invention relates to an auto-erase chalkboard of water-writing cloth, comprising a frame, a water-writing cloth first pulley, a motor, three thin plastic rollers, a second pulley, a second V-belt, a first thick plastic roller, a sponge pad, a steel sheet, a control panel, a second thick plastic roller, an electric hot air blower, and a first V-belt. The auto-erase chalkboard of water-writing cloth has the advantages that the defect that writing on the traditional electric chalkboard causes dust is changed, a water pen is developed and manufactured according to the writing principle of the water-writing cloth, writing is smooth, writings are attractive, the defects that the traditional auto-erase chalkboard is high in noise and is incompletely erased are overcome, and the auto-erase chalkboard of water-writing cloth is simple in structure, low in cost, environmentally friendly, pollution free, and especially capable of serving as an optimal choice for teachers who write on the chalkboard often.
Description
Technical field
The present invention relates to a kind of writing implement, especially a kind of water writes cloth auto-erasing blackboard.
Background technology
Traditional blackboard chalk is write on plate face, is not only difficult to wiping and also can produces a large amount of dust pollution Classroom airs simultaneously, be unfavorable for that academics and students' is healthy.Even if having there is dust-free chalk and the blank teaching of improvement in the later stage, but cannot solve low-carbon (LC), environmental protection, dustless practical problem.Teaching blank is smooth, have higher reflective, easily causes partial students cannot see writing on plate face, has higher contrast, reflective, easily allows student produce visual fatigue and harm one's eyes.Not environmentally, alcohol content is high for the expensive and major part of the board pen ink simultaneously used, and harmful teachers and students are healthy.
Multimedia teaching and electronic whiteboard teaching are another category strictly speaking.Because equipment price is high, maintenance and maintenance expense are comparatively large, can only use in minority area.Multimedia teaching simultaneously and electronic whiteboard teaching make teaching speed accelerate, and contain much information large increasing, and focal points are not given prominence to.Student does not have the time thought deeply and analyze on classroom, has half knowledge, cannot digest knowledge point.In addition from Chinese characters culture, the distinctive Calligraph Art of Chinese character, writes when teacher imparts knowledge to students every stroke and just can reach better teaching efficiency on blackboard.So although traditional chalk has dust, but the love knot that teacher loath to parts from each other.Traditional chalk and multimedia all can consume a large amount of manpower and financial resources, do not meet the thought of energy-conserving and environment-protective.Therefore, the present invention proposes the Design Conception that a kind of water writes cloth auto-erasing blackboard.
Summary of the invention
In order to solve traditional chalk and multimedia all can consume a large amount of manpower and financial resources, do not meet the thought of energy-conserving and environment-protective, the present invention proposes a kind of water and writes cloth auto-erasing blackboard, comprise frame, water writes cloth, first belt pulley, motor, three thin plastic drums, second belt pulley, second V belt, first thick plastic drum, foam-rubber cushion, stalloy, control panel, second thick plastic drum, electric-heating air blower and the first V belt, described motor is installed in frame, first belt pulley is connected with motor by its central shaft, first thick plastic drum is placed in frame top, second thick plastic drum is placed in frame inner bottom part, in frame, crossbeam is installed, electric-heating air blower and three thin plastic drums are placed on crossbeam respectively, described first thick plastic drum, second thick plastic drum, threaded engagement is carried out respectively by the bearing and bearing block that pass its central shaft, bearing block is bolted to be fixed with frame respectively, three described thin plastic drums carry out threaded engagement by the bearing and bearing block that pass its central shaft respectively, bearing block is bolted to be fixed with the crossbeam in frame respectively, first belt pulley is connected with the second thick plastic drum by the first V belt, second thick plastic drum is connected with the first thick plastic drum by the second V belt, described water writes cloth, first thick plastic drum, the pretightning force that second thick plastic drum and three thin plastic drums write cloth by water connects, water is equipped with foam-rubber cushion after writing cloth, stalloy is equipped with after foam-rubber cushion, foam-rubber cushion and stalloy are bolted in frame, described electric-heating air blower is connected with electric-heating air blower mouthpiece by plastic tube, described electric-heating air blower and electric-heating air blower mouthpiece are fixed in frame respectively by elastic rubber band, described control panel is placed in frame side, this control panel there are three button: K1, K2 and K3, first button K1 is that motor rotates forward, water is driven to write the motion of cloth positive direction, second button K2 is that motor and electric-heating air blower start simultaneously, write cloth to water to dry up, the word that erasing is write above, 3rd button K3 electric-heating air blower starts, write cloth to water to dry up, the word that erasing is write above.
The middle part of the described first thick plastic drum, the second thick plastic drum and three thin plastic drums respectively has a groove.
The invention has the beneficial effects as follows, the present invention changes driven blackboard in the past and has write dust drawback, and the principle utilizing water to write cloth to write, avoids auto-erasing blackboard noise in the past large, wipe sordid shortcoming.Structure of the present invention is simple, with low cost, environment friendly and pollution-free.Especially to the selection that frequent writing on the blackboard teacher is best especially.
