Abstract

The invention discloses a blackboard with a dust prevention function. The blackboard with the dust prevention function comprises a frame, a pair of driving synchronous pulleys driven by a turbine gear motor and a pair of driven synchronous pulleys, wherein the driving synchronous pulleys and the driven synchronous pulleys are arranged on the frame. A pair of tensioning synchronous pulleys is arranged between the driving synchronous pulleys and the driven synchronous pulleys. The turbine gear motor is arranged below the driving synchronous pulleys on the frame. A roller a supported by a bearing block of the roller is arranged below the turbine gear motor on the frame. A roller b driven by a roller motor is arranged above the driven synchronous pulleys on the frame. A rubber plate is connected to the outer surfaces of the driving synchronous pulleys, the tensioning synchronous pulleys and the driven synchronous pulleys to form a rotating blackboard loop when the turbine gear motor drives the synchronous pulleys to rotate. The roller a and the roller b are in contact with the surface of the rotating blackboard loop. The roll motor drives the roller b to rotate to remove chalk dust on the surface of the blackboard. The blackboard with the dust prevention function is simple, practical and good in dust removal effect and avoids the harm of dust to a body in a using process.

Description

technical field [0001] The invention relates to a blackboard, in particular to an automatic dustproof blackboard with dustproof function. Background technique [0002] With the rapid development of education, although various teaching equipment and instruments are constantly being updated, the use of modern teaching methods and equipment is replacing the old traditional teaching step by step, but in the long process of excessive development, the use of traditional blackboards still occupy a large proportion. For more than two hundred years, blackboards have witnessed the development of education from the earliest black paint on the surface of hard objects such as wood boards and cement to the ground glass in the 1990s, and now to the color-coated steel plates and composite materials. Now the types of blackboards have also begun to become complex and diverse, divided into black, white, green and so on from the color. From the mechanism, it can be divided into bracket activi...
