Abstract

The invention provides a compound erasing type board erasing device, which comprises a bracket and a drive motor arranged at the bracket, a transmission mechanism connected with the output terminal of the motor and an erasing mechanism connected with the transmission mechanism; the erasing mechanism comprises an erasing head; the erasing head moves linearly; the erasing head comprises an erasing roller and an erasing pressure rod arranged in parallel with the erasing roller; the compound erasing type board erasing device of the invention has the beneficial effect that: the erasing pressure rod which is arranged in parallel with the erasing roller is adopted and further erasing by the erasing pressure rod after carrying out erasing by the erasing roller is carried out, thereby greatly improving the cleanliness of the surface that is erased; besides, the erasing roller adopts a hollow air suction structure, thus being beneficial to sucking the dust of chalk handwritings and improving the environment.

Description

【Technical field】 [0001] The invention relates to the technical field of board surface wiping, in particular to a double wiping type board wiping device. 【Background technique】 [0002] The board is a tool for disseminating culture, and it is an indispensable part of teacher teaching, student learning or blackboard propaganda. The existing boards include blackboards or whiteboards. At present, most of the erasers are hand-held erasers, which are slow and inefficient because they must be moved by hand, and the hands are prone to fatigue, which affects teaching. [0003] Another kind of automatic blackboard eraser, this blackboard eraser comprises horizontal transmission unit, is arranged on the vertical fixed plate that can drive horizontally with it and moves horizontally on the horizontal transmission unit, this fixed plate is provided with automatic body wiper element, and this automatic body wiper element is made of A plurality of rotating body-wiping parts arranged side...
