Problems solved by technology

[0002] Traditional blackboards need to be manually erased, and a large amount of dust will be generated during the erasing process, which will cause great harm to the health of users
[0003] Therefore, the birth of the environmentally friendly blackboard has effectively solved this problem. The existing environmentally friendly blackboards are mostly locked on the wall by passing through the wall screws, and are driven by internal multi-motors and a relatively complicated transmission mechanism. This structural feature leads to the following technologies Problems: 1. Installation is inconvenient; 2. Complex structure and high production cost; 3. Inconvenient maintenance after problems occur; 4. Does not have self-erasing function, or cannot realize regional selective erasing

Abstract

The invention discloses a blackboard and particularly relates to a self-erasure environmental-friendly blackboard, which comprises a rack and is characterized in that the left end and the right end of the rack are respectively provided with a board left-end rotating roller and a board right-end rotating roller, an environmental-friendly board is sheathed on the board left-end rotating roller and the board right-end rotating roller, a first synchronous belt pulley is in linkage connection with a board rotation driving motor, a second synchronous belt pulley is in linkage connection with the first synchronous belt pulley through a synchronous belt and is fixedly arranged on the board left-end rotating roller, an eraser box sliding rod is longitudinally arranged on the rack, an eraser box is movably arranged on the eraser box sliding rod, a third synchronous belt pulley is in linkage connection with an eraser driving motor, an eraser movement synchronous belt is arranged on the third synchronous belt pulley, the eraser box and the eraser movement synchronous belt are in linkage connection, and a dust collecting box is arranged below the eraser box. The self-erasure environmental-friendly blackboard has the characteristics of simple structure, convenience for operation and maintenance, and capability of realizing automatic erasure by regions and automatic dust collection.

Description

technical field [0001] The invention relates to a blackboard, in particular to a self-erasing environment-friendly blackboard. Background technique [0002] Traditional blackboards need to be erased manually, and the erasing process will generate a lot of dust, which will cause great harm to the health of users. [0003] Therefore, the birth of the environmentally friendly blackboard has effectively solved this problem. The existing environmentally friendly blackboards are mostly locked on the wall by passing through the wall screws, and are driven by internal multi-motors and a relatively complicated transmission mechanism. This structural feature leads to the following technologies Problems: 1. It is inconvenient to install; 2. The structure is complicated and the production cost is high; 3. It is inconvenient to maintain after a problem occurs; 4. It does not have the self-erasing function, or it cannot realize regional selective erasing. [0004] Based on this, make the...
