English display board with adjusting function

Abstract

The invention discloses an English display board with an adjusting function, relates to the technical field of display boards, and solves the problems that when handwriting on a display board is manually erased at present, the handwriting on the display board cannot be completely erased at one time, repeated erasing is needed, and time and labor are wasted. The English display board with an adjusting function comprises a cleaning and positioning assembly. The cleaning and positioning assembly comprises a positioning frame, the positioning frame is connected to the outer side of a board body of the display board in an inserted mode, and a reverse erasing assembly is installed in the positioning frame. When the device erases the handwriting on the surface of the display board, a driving assembly drives the cleaning and positioning assembly and the reverse erasing assembly to rapidly and thoroughly erase the handwriting on the surface of the display board, and the rotating direction of the binding face of the erasing cylinder and the display board is the same as the moving direction of the cleaning and positioning assembly. The friction force between the erasing cylinder and the surface of the display board can be increased, the erasing time can be prolonged, the writing on the surface of the display board can be erased quickly and thoroughly, and convenience and flexibility are achieved.
