When the pressure reaches the preset pressure, namely the assembly of the wiping roller is judged to reach the working position, the hydraulic cylinder cannot extend continuously, the oil pressure of the pipeline rises, the action pressure of the pressure switch is reached, the pipeline is closed, the oil supply is stopped, and the hydraulic cylinder 32 is kept at the working position to carry out wiping operation.
