The rotating roller 104 and the supporting roller 105 are located on the inner side of the display belt 107, and the winding roller 106 is located on the outer side of the display belt 107. The display belt 107 is connected end to end around the winding roller 106, and the display belt 107 is wound around the winding roller 106. 07 is rolled up and folded, thereby increasing the length of the display belt 107 without increasing the occupied space, thereby increasing the writing area; the driving component 110 can drive the cleaning brush 108 to move forward and backward; when in use, the teacher writes and writes on the blackboard on the display belt 107, thereby conducting ideological and political teaching. When the front side of the display belt 107 is full of blackboard writing, the driving component 110 drives the rotating roller 104 to rotate, thereby driving the display belt 107 to rotate, so that the blackboard writing on the display belt 107 rotates to the back, and the display belt 107 without writing rotates to the front, which is convenient for the teacher to continue writing and teaching. In this way, not only does it not need to erase the blackboard writing during the teaching process, but the previous blackboard writing can also be saved. ; When the teaching is completed, the rotating roller 104 can continue to rotate, so that the previous blackboard writing can be rotated to the front again, which is convenient for students to review the previous blackboard writing content; when it is necessary to clean the writing on the display belt 107, the driving component 110 and the rotating component 109 are started at the same time, and the driving component 110 drives the cleaning brush 108 to move, so that the cleaning brush 108 abuts against the surface of the display belt 107. At this time, the rotating component 109 drives the rotating roller 104 to rotate, and then drives the display belt 107 to rotate, so that the surface of the display belt 107 is brushed by the cleaning brush 108, and then the writing on the display belt 107 is erased, thereby achieving the purpose of improving the writing and display effects.

[0028] Secondly, the rotating shaft 111 is fixedly connected to the rotating roller 104, and is rotatably connected to the mounting frame 102, and is located on one side of the rotating roller 104; the worm wheel 112 is fixedly connected to the rotating shaft 111, and is sleeved on the rotating shaft 111; the rotating motor 114 is connected to the mounting frame 102, and is located on one side of the mounting frame 102; the worm 113 is arranged on the rotating motor 114, and is connected to the output end of the rotating motor 114; the worm 113 is driven to rotate by the rotating motor 114, and the worm 113 drives the worm wheel 112 to rotate, thereby driving the rotating shaft 111 and the rotating roller 104 to rotate, thereby achieving the purpose of driving the rotating roller 104 to rotate; at the same time, through the self-locking property between the worm wheel 112 and the worm 113, the stability of the rotating roller 104 is improved, and then the stability of the display belt 107 is improved.

[0029] At the same time, the shaft 115 is rotatably connected to the mounting frame 102 and is arranged on the mounting frame 102; the rubber wheel 116 is fixedly connected to the shaft 115, abuts against the display belt 107, and is sleeved on the shaft 115; two rubber wheels 116 are provided, and are respectively located at the left and right ends of the shaft 115. The rubber wheels 116 are in contact with both sides of the display belt 107 to prevent the blackboard writing in the middle from being blurred due to friction. At the same time, the rubber wheels 116 are elastic and can avoid damage to the surface of the display belt 107.

[0030] In addition, the support plate 117 is fixedly connected to the mounting frame 102, abuts against the display belt 107, and is arranged on the mounting frame 102; the support plate 117 supports the front side of the display belt 107, so that when the teacher writes, the display belt 107 will not be sunken, thereby avoiding affecting the teacher's writing.

[0031] When using the display device of this embodiment, the display belt 107 is used to display the blackboard writing. The teacher can write directly on the outer layer of the display belt 107, and can easily leave clear handwriting with ordinary chalk. When the front side of the display belt 107 is full of blackboard writing, the teacher does not need to interrupt the teaching to erase the blackboard writing. The rotating roller 104 can be driven to rotate by the rotating member 109 to rotate the full blackboard writing part to the back, and the unwritten part can be automatically rotated to the front for the teacher to continue writing. This process not only saves the time of erasing the blackboard writing, but also retains the previous blackboard writing content, which is convenient for students to review at any time. In addition, when the display belt 107 needs to be erased, the teacher can also use the rotating roller 104 to rotate the rotating member 109 to rotate the rotating roller 104 to rotate the full blackboard writing part to the back, and the unwritten part can be automatically rotated to the front for the teacher to continue writing. This process not only saves the time of erasing the blackboard writing, but also retains the previous blackboard writing content, which is convenient for students to review at any time. When cleaning the handwriting on the display belt 107, the teacher can start the driving component 110 and the rotating component 109 at the same time. The driving component 110 drives the cleaning brush 108 to move back and forth until the cleaning brush 108 is in close contact with the surface of the display belt 107. Then, the rotating component 109 drives the worm 113 to rotate through the rotating motor 114, and the worm 113 drives the worm wheel 112 and the rotating shaft 111 to rotate, thereby driving the rotating roller 104 and the display belt 107 to rotate. As the display belt 107 rotates, its surface will be brushed by the cleaning brush 108, effectively erasing the handwriting, thereby achieving the purpose of writing and displaying effects.
