Description

Technical Field

[0001] The utility model relates to the field of aerated concrete equipment, in particular to a roughening device for autoclaved aerated concrete slabs. Background Art

[0002] Autoclaved aerated concrete board is a new type of lightweight, porous, green and environmentally friendly building material with cement, lime, silica sand and other raw materials as the main raw materials, and different amounts of anti-corrosion treated steel mesh are added according to the structural requirements. Roughening technology is a construction method. Because the smooth autoclaved aerated concrete board cannot be pasted on the wall, many grooves are scratched on the autoclaved aerated concrete board to facilitate the pasting of the autoclaved aerated concrete board on the wall.

[0003] The utility model patent with Chinese patent application number CN202310081727.6 discloses a roughening device for an autoclaved aerated concrete board, including a covering box and a roughening component arranged inside the covering box, wherein a height adjustment component is slidably installed inside the covering box, and the roughening device for the autoclaved aerated concrete board drives the assembly plate to rotate by utilizing a driving member. During the movement of the covering box, the first serrated plate performs interval punching on the surface of the autoclaved aerated concrete board, and divides the surface of the autoclaved aerated concrete board into several sections of areas to be roughened. The assembly plate is controlled to rotate by the driving member, so that the latch extrusion component is inserted into the top hole, and the second serrated plate is squeezed to the position where the holes are punched on the autoclaved aerated concrete board. By moving the covering box, the roughening treatment can be performed on several sections of the areas to be roughened, and the overall roughening stroke is shortened while effectively avoiding the occurrence of large-scale shedding on the surface of the autoclaved aerated concrete board.

[0004] However, the textures of the roughened concrete slabs by the equipment are straight lines to increase the surface area, and there is still a lot of room for increasing the surface area. Utility Model Content

[0005] In view of the above problems, the utility model provides a device for roughening an autoclaved aerated concrete slab, which conveys the concrete slab on a roller conveyor and passes under a scraper. The mobile component drives the scraper to move horizontally left and right, thereby producing wavy lines on the concrete surface. At the same time, a cleaning brush can brush up the dust in the lines and suck it out through an external dust suction device, thereby further increasing the surface area of ​​the concrete slab compared to the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
