Abstract
The utility model discloses an electric blackboard cleaning device comprising an eraser, an upper cross beam and a lower cross beam. The upper cross beam is arranged on the upper portion of a blackboard, and the lower cross beam is arranged on the lower portion of the blackboard. An eraser fixator is arranged between the upper cross bean and the lower cross beam, and the eraser is mounted the eraser fixator. A power-driven mechanism is further arranged on the eraser fixator, and drives the eraser fixator to move along the upper cross beam and the lower cross beam. By the arrangement of the upper cross beam and the lower cross beam on the blackboard and the eraser fixator moving along the upper cross beam and the lower cross beam, the eraser is enabled to perform reciprocating motion, automatic cleaning of the blackboard is realized, and labor and time are greatly saved.

Be provided with the blackboard eraser fixator between described entablature and sill, described blackboard eraser is installed on this blackboard eraser fixator;
Also be provided with motor drive mechanism on described blackboard eraser fixator, described motor drive mechanism drives described blackboard eraser fixator to move along entablature and sill.
In driven blackboard cleaning device described in the utility model, the two ends of described entablature be respectively arranged with for the fixing upper bracket in blackboard top; The two ends of described sill be respectively arranged with for the fixing lower carriage in blackboard bottom.
In driven blackboard cleaning device described in the utility model, described blackboard eraser fixator comprises the connecting plate be across on entablature and sill, and described blackboard eraser is dismountable to be installed on this connecting plate.
In driven blackboard cleaning device described in the utility model, described entablature is provided with Timing Belt, and described sill is provided with lower Timing Belt;
Described motor drive mechanism comprises upper motor and the lower motor that is divided into described connecting plate two ends; Wherein, the output shaft of described upper motor is connected with and cogs, and this cogs and described upper Timing Belt engagement; The output shaft of described lower motor is connected with lower gear, described lower gear and described lower Timing Belt engagement.
In driven blackboard cleaning device described in the utility model, described connecting plate is connected by linear bearing with described entablature, sill respectively.
In driven blackboard cleaning device described in the utility model, the upper bracket at described entablature two ends is respectively arranged with travel switch, and when described blackboard eraser fixator contacts with described travel switch, described motor drive mechanism stops driving described blackboard eraser fixator to move.
In driven blackboard cleaning device described in the utility model, by entablature and sill are set on blackboard, and the blackboard eraser fixator moved along entablature and sill is set, make it possible to achieve blackboard eraser moves back and forth on blackboard, also realized Automatic erasing blackboard, manpower and the time of greatly saving.
The accompanying drawing explanation
The structural representation that Fig. 1 is driven blackboard cleaning device described in the utility model.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, driven blackboard cleaning device described in the utility model, comprise blackboard eraser 21, also comprises the entablature 3 that is arranged at blackboard 1 top and the sill 4 that is arranged at blackboard 1 bottom.Be provided with blackboard eraser fixator 2 between described entablature 3 and sill 4, described blackboard eraser 21 is installed on this blackboard eraser fixator 2.Also be provided with motor drive mechanism on described blackboard eraser fixator 2, described motor drive mechanism can drive described blackboard eraser fixator 2 to move along entablature 3 and sill 4.Described blackboard eraser fixator 2 drives blackboard eraser 21 and slips on blackboard 1, thereby blackboard-cleaning is clean.
Particularly, as shown in Figure 1, at the two ends of described entablature 3, be respectively arranged with for the fixing upper bracket 31,32 in blackboard 1 top; The two ends of described sill 4 be respectively arranged with for the fixing lower carriage 41,42 in blackboard 1 bottom.2 of described blackboard eraser fixators specifically comprise the connecting plate 22 be across on entablature 3 and sill 4, and described blackboard eraser 21 is dismountable to be installed on this connecting plate 22, by bolt 23 or other removablies, install.
In the utility model, for realizing connecting plate 22 synchronizing moving up and down in the horizontal direction, also on described entablature 3, be provided with the Timing Belt (not shown), be provided with lower Timing Belt (not shown) on described sill 4.Described motor drive mechanism specifically comprises upper motor 24 and the lower motor 25 that is divided into described connecting plate 22 two ends; Wherein, the output shaft of described upper motor 24 is connected with the (not shown) that cogs, and this cogs and described upper Timing Belt engagement; The output shaft of described lower motor 25 is connected with the lower gear (not shown), described lower gear and described lower Timing Belt engagement.Like this, when described upper motor 24 and lower motor 25 synchronous rotation, due to the acting in conjunction of upper Timing Belt and lower Timing Belt, make described connecting plate 22 smooth sliding in the horizontal direction.
In the utility model, described connecting plate 22 is connected by linear bearing with described entablature 3, sill 4 respectively, to reduce the wearing and tearing between each several part, and increases the service life.
Be further, also the upper bracket 31,32 at described entablature 3 two ends is respectively arranged with travel switch 34,33, as described blackboard eraser fixator 2 and described travel switch 34(or 33) while contacting, described motor drive mechanism stops driving described blackboard eraser fixator 2 to move, thereby makes blackboard eraser fixator 2 rest on an end of blackboard 1.When motor drive mechanism starts again, can control by the electrode direction of regulating power supply the direction of rotation of motor, thereby control the moving direction of blackboard eraser fixator 2.The embodiment of comparative optimization is, when blackboard eraser fixator 2 each runs are also removed travel switch to the end of blackboard 1, all regulate the electrode direction of power supply, thereby make blackboard eraser fixator 2 constantly move to the other end of blackboard 1 at next, also realize the reciprocating motion of blackboard eraser fixator 2.
In driven blackboard cleaning device described in the utility model, by entablature and sill are set on blackboard, and the blackboard eraser fixator moved along entablature and sill is set, make it possible to achieve blackboard eraser moves back and forth on blackboard, also realized Automatic erasing blackboard, manpower and the time of greatly saving.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
