The utility model is the automatic blackboard eraser device with simple structure, convenient operation and controllability.
Description
Technical field
The utility model relates to a kind of school supply and stationery, especially relates to the automatic eraser device of chalk writing on a kind of erasing blackboard.
Background technology
It is very simple and crude to have the blackboard eraser that is used to wipe the writing on the blackboard now, only be at the fixing panniform bristle of the one side of blackboard eraser, utilize the erasing back and forth on the blackboard writing of felt hair, writing is wiped from blackboard, reach the purpose of removing writing on the blackboard, adopt the writing on this blackboard eraser brushing blackboard, the writing dust is floated in the air on the blackboard surface, make people be subjected to the evil of dust pollution deeply, influence the healthy of user, frequent erasing blackboard is also bigger to people's physical demands in short time simultaneously.People have designed the blackboard eraser of some automatic brushing blackboards under external force drives now, but the most complex structure of the blackboard eraser of these automatic brushing blackboards, unusual inconvenience when installing and change blackboard eraser, and handling in use relatively poor, bring some inconvenience for people's use.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind of simple in structure, easy automatic eraser device of controlling of user.
For solving the problems of the technologies described above, the technical solution of the utility model is: automatic eraser device, comprise the guide rail that is set in parallel in the blackboard above and below, be provided with the support that can reciprocatingly slide at the driving lower edge of drive unit two guide rails between two guide rails, but support is provided with the blackboard eraser of brushing blackboard, and described blackboard both sides are respectively equipped with can control the reciprocatingly slide control device of traverse of support; Described guide rail is respectively equipped with the adjusting device that can adjust two guide rail positions.
As a kind of improvement, described drive unit comprises the drive motors that support is provided with, and is provided with the driving wheel that can rotate under drive motors drives between described support and the described guide rail.
As further improvement, described drive unit comprises drive motors and is arranged on the directive wheel of described blackboard side, be provided with between described support and the directive wheel can the tractive support reciprocatingly slides along two guide rails under drive motors drives rope.
As further improvement, the length of described blackboard eraser is identical with the blackboard height.
As further improvement, be respectively equipped with guide wheel between described support and the guide rail.
As further improvement, described control device is the limit switch that is connected with the drive motors control system.
As further improvement, described support is provided with the elastic device that blackboard eraser can be pushed to blackboard.
The automatic eraser device of technique scheme, owing to be to have adopted the guide rail that is set in parallel in the blackboard above and below, be provided with the support that can reciprocatingly slide at the driving lower edge of drive unit two guide rails between two guide rails, but support is provided with the blackboard eraser of brushing blackboard, is respectively equipped with in the blackboard both sides to control the reciprocatingly slide control device of traverse of support; Be respectively equipped with the adjusting device that to adjust two guide rail positions at guide rail, control the slip traverse of support easily by the control device that is provided with, thereby control is arranged on the slip traverse of blackboard eraser on the support, reaches the purpose of control blackboard eraser brushing blackboard, and is convenient easy to operate; Adjust two guide rail positions by adjusting device, realizing installation easily to support, and and blackboard between the adjustment of position so that use.Employing is provided with drive motors and drives driving wheel on support, the mode that perhaps adopts directive wheel to cooperate with rope can be selected different type of drive according to different environments for use.The length of employing blackboard eraser is identical with the blackboard height and be respectively equipped with guide wheel between support and guide rail, can further facilitate people's use.Control device adopts the limit switch be connected with the drive motors control system, and is simple in structure, is provided with the elastic device that blackboard eraser can be pushed to blackboard on support, and the bristle of blackboard eraser is remained and the contacting of blackboard, clean to the brushing of writing with assurance.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is the structural representation of the utility model automatic eraser device;
Fig. 2 is the structural representation of the utility model automatic eraser device one embodiment.
The specific embodiment
As accompanying drawing 1, automatic eraser device, comprise the guide rail 2 that is set in parallel in blackboard 1 above and below, be provided with support 3 between two guide rails, support 3 can reciprocatingly slide at the driving lower edge of drive unit two guide rails, for convenience the slip of support 3, between support 3 and guide rail 2, be respectively equipped with guide wheel 6, support 3 is connected with guide rail 2 by guide wheel 6, has reduced the resistance that reciprocatingly slides greatly, has made things convenient for people's use.Drive unit can adopt small-sized drive motors, but on support 3, be provided with the blackboard eraser 4 of brushing blackboard 1, be respectively equipped with in blackboard 1 both sides and can control the reciprocatingly slide control device 7 of traverse of support 3, for simple in structure, control device 7 can adopt the limit switch that is connected with drive motors 5 control systems, like this, and the interaction of the support 3 by blackboard 1 both sides limit switch and slip, control the traverse that support 3 reciprocatingly slides, with convenient use to automatic eraser device; And be respectively equipped with the adjusting device 8 that to adjust two guide rail positions at guide rail 2, adjust the relative distance between the fixtures such as wall of guide rail 2 and blackboard 1 or fixed guide 2 by adjusting device 8, and two distances between the guide rail, with easy to install and use, as adopting the mode of regulating bolt.
