Description

Technical Field

[0001] The utility model relates to the technical field of cleaning the surface layer of road brick blanks, in particular to a cleaning device for the surface layer of road brick blanks. Background Art

[0002] Pavement bricks are a kind of material that is mainly made of cement, gravel, coal slag, coal gangue, sand and other raw materials through stamping and forming by stamping presses. They are often used as paving materials for urban road sidewalks, city squares, gardens, communities and other roads. During the pressing and conveying process of the brick blanks of pavement bricks by the stamping presses, some fine slag adhered to the stamping presses will fall on the surface layer of the brick blanks. If they are not cleaned in time, these fine slag will solidify on the surface layer of the brick blanks during the curing and drying process, affecting the smoothness and flatness of the surface layer of the brick blanks. Therefore, after the brick blanks are pressed, the surface layer of the brick blanks needs to be cleaned of impurities.

[0003] In the prior art, a cleaning brush device is generally used for cleaning. For example, the authorization announcement number CN220030621U discloses a brick blank surface cleaning device, in which a cleaning brush is fixedly connected to one end of a horizontal conveyor belt. The horizontal conveyor belt drives the brick blank to pass under the cleaning brush, and the cleaning brush is driven by a motor to clean the surface of the brick blank. However, this cleaning brush device still has defects during actual use: since the surface layer of the brick blank is relatively fragile just after the brick blank is pressed and formed, when the cleaning brush device is used for cleaning, the brush body is easy to damage the surface layer of the brick blank.
