The invention relates to the field of building board
processing, in particular to a board cleaning device in the building field. The board cleaning device comprises a feeding mechanism, a liquid conveying mechanism, a soaking
assembly, a rolling mechanism and three sets of cleaning assemblies, the feeding mechanism is vertically arranged, and the soaking
assembly comprises a moving mechanism, a stabilizing mechanism and a shifting mechanism; the rolling mechanism is arranged on the side, away from the liquid conveying mechanism, of the soaking
assembly, each set of cleaning assembly comprises a rolling
brush mechanism, a lifting mechanism and a spraying mechanism, and through cooperative operation of the feeding mechanism and a driving mechanism, automatic conveying is achieved, and input of the labor amount is reduced; through the arrangement of the soaking assembly, boards are soaked firstly, so that the fitting degree of dust and impurities on the surfaces of the boards and the boards is reduced, follow-up cleaning is facilitated, the height between the rolling
brush mechanism and the boards can be adjusted through the lifting mechanism, and therefore the board cleaning device adapts to cleaning of the plates of different sizes; and the spraying mechanism sprays when the rolling
brush mechanism performs rolling brushing, and washed impurities can conveniently flow away through sprayed
water flow.
