Abstract

The utility model relates to an auto blackboard eraser device. The shell is provided with a frame and the frame is provided with symmetrical transmission shaft. The transmission shaft is provided with wide plastic curtain and the curtain is fixed on the frame by the scale board on the back of the curtain. The frame is provided with approach grafting brush cleaning roller and blanket moisture absorption roller on the horizon direction of the bottom, wherein the brush cleaning roller is provided with sunk on the bottom. The frame is provided with electric motor on the bottom of the side surface and the motor transmission wheel mounted on the output shaft forms a transmission device with the separating boards mounted on the two ends of the transmission shaft head, after passing the belt, the transmission shaft and a transmission wheel mounted on the side of the brush cleaning roller. The utility model is compacted in structure, reasonable in design, swift in use and not restricted by the writing board. The device of wide plastic curtain rolls repeated to ensure the teachers not restricted by the board by removing the character on the wide plastic curtain with blanket moisture absorption roller.

Description

Driven type Automatic erasing blackboard device

Technical field

The utility model relates to a kind of new type blackboard, definite a kind of driven type Automatic erasing blackboard device of saying so.

Background technology

Traditional blackboard is the glass (frosted glass) that is fixed with on the framework through processing, is fixed on the wallboard and imparts knowledge to students, and this product is not easy to the faculty and writes, and the plate face is limited, wiping repeatedly after writing, and the powder after the wiping is scattered everywhere, pollutes classroom environment.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, driven type Automatic erasing blackboard device convenient to use.

In order to achieve the above object, the technical solution adopted in the utility model is: framework is installed in housing, the bar of parallel drive shaft up and down of symmetry is housed on it, be with wide cut plastic cement curtain on the transmission shaft lever, its rear end has liner plate to be fixed on the framework, framework lower end part horizontal direction is equipped with hairbrush wiping roller bearing and the felt moisture absorption roller bearing that is abutted against mutually, hairbrush wiping roller bearing below is equipped with tank, framework one side lower end part is fixed with motor, the electric-motor drive of assembling on its output shaft wheel through belt be connected with the drive of transmission shaft lever and the assembling of hairbrush wiping roller bearing side with two ends, transmission shaft lever termination on the separating plate installed cooperate the formation transmission device.

The utility model has the advantages that:

Compact conformation, reasonable in design, convenient to use, the clipboard face is unrestricted, this device is write the use of can rolling repeatedly of wide cut plastic cement curtain, being convenient to faculty's use not limited by the plate face, because felt moisture absorption roller bearing is wiped the writing on the wide cut plastic cement curtain, its dust falls automatically as preventing the pollution to surrounding environment in the tank.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 3 as can be known, the utility model is

When using the utility model, connect power supply, the motor rotation drives transmission device work, at this moment, being sleeved on two wide cut plastic cement curtains on the power transmission shaft moves clockwise, when wide cut plastic cement curtain is not worked, the faculty can write on wide cut plastic cement curtain, can start power supply (foot pedal type button or manual power switch) wide cut plastic cement curtain according to faculty's clipboard face and rotate to certain altitude, be desirable height, then, can continue on the wide cut plastic cement curtain of no writing, to continue to write, be convenient to the conciliation of seat, bring great convenience to the faculty at row personnel visual angle, back.During writing on needing wiping wide cut plastic cement curtain, regulate separating plate and make the hairbrush wiping roller bearing and the felt moisture absorption roller bearing spacing position of being abutted against mutually, writing can be wiped, the utility model can be suspended on the wall, also the housing seat can be crouched on the dais.
