The invention relates to an automatic unloading and rolling former for a building decorative material designed cement brick. The automatic unloading and rolling former comprises a conveying supporting device, a mould frame device, a stirring device, an automatic unloading device and a compacting rolling device, wherein the mould frame device is arranged on the conveying supporting device; the stirring device is mounted at the left side of the conveying supporting device; the automatic unloading device is mounted on the stirring device; and the compacting rolling device is mounted on the conveying supporting device. The automatic unloading and rolling former solves the problems that working efficiency of manually processing the designed cement brick in the prior art is low, labor power is needed for stirring and unloading designed cement brick base stock, labor power is needed for vibrating and rolling the designed cement brick base stock, the designed cement brick is difficult to take out from a mould, and the like, can realize functions of controlling the designed cement brick base stock to automatically unload during designed cement brick processing and automatically vibrating, rolling and forming the designed cement brick, and has the advantages of being high in working efficiency, mechanically stirring and unloading the designed cement brick base stock, mechanically vibrating and rolling the designed cement brick, easily taking out the processed designed cement brick from the mould, and the like.
