Description

A conveyor belt type electric writing board

technical field

The present invention is a kind of teaching implement, a kind of conveyor belt type electric writing board.

Background technique

The writing board is the most commonly used tool in teaching activities. Existing writing board still is based on traditional hard blackboard, uses this hard blackboard to have many drawbacks.

1. Handwriting needs to be erased manually, which may cause dust pollution.

2, when the person who writes is not tall enough, it is difficult to write handwriting on the writing board to the position that is convenient to observe, and this has brought inconvenience to blackboard layout.

3. In some cases, it is difficult for people who are far away from the writing board to observe the content near the lower edge of the writing board.

Design a kind of writing board that can solve above-mentioned drawback seems very significant.

Contents of the invention

The invention is a conveyor belt type electric writing board, which has the characteristics of simple structure, convenient use, low cost, etc., and is suitable for schools and various training institutions.

Description of drawings

Fig. 1 is to observe a kind of conveyor belt type electric writing board from the side, a kind of schematic diagram of conveyor belt type electric writing board.

Fig. 2 is a schematic diagram of a conveyor belt type electric writing board observed from the front, a kind of conveyor belt type electric writing board.

Fig. 3 is a schematic diagram of the remote controller.

Reference sign

Drive wheel 1, bracket 2, board cloth 3, back plate 4, bracket 5, runner 6, dust collection tank 7, brush 8, board frame 9, motor 10, motor 11, controller 12, remote control 13.

Detailed ways

The upper and lower ends of the backboard 1 are respectively equipped with a bracket 2 and a bracket 5, the bracket 2 is equipped with a transmission wheel 1, and the bracket 5 is equipped with a runner 6 and a brush 8, and one end of the shaft of the transmission wheel 1 is connected to the rotating shaft of the motor 10 , One end of the shaft of the brush 8 is connected to the rotating shaft of the motor 11, the backboard 4 is equipped with a frame 9, and the frame 9 can be installed on a wall or other carrier. The controller 12 can receive the control command sent by the remote controller 13, and can control the motor 10, the motor 11 to start, stop, forward and reverse according to the control command. The remote controller 13 is used to send control commands.

The backboard 4 has a supporting effect on the board cloth 3, which is conducive to the smooth progress of writing. The handwriting to be written can be written on the board cloth 3. When erasing the writing on the board cloth 3, you only need to press the down button of the remote controller 13, and the controller 12 will control the motor 10 to rotate clockwise to drive the board cloth 3 move down. At the same time, the motor 11 rotates counterclockwise, and the brush 8 rotates counterclockwise relative to the plate cloth 3 . Like this, hairbrush 8 can erase the handwriting on the plate cloth 3. Erase handwriting on plate cloth 3 as produce dust, dust can be concentrated in the dust collection groove 7 lis of plate cloth 3 belows mostly. In this way, dust pollution caused by erasing handwriting can be effectively avoided.

After writing on a conveyor-belt type electric writing board, press the up or down button of the remote controller 13 to control the board cloth 3 to move up or down, so that the handwriting on the board cloth 3 can be moved to a position that is easy to observe. Location.
