The invention discloses a quick cement sculpture forming machine which comprises a cement filling device, a seat frame, a setting belt, a setting belt support frame and a vertical driving mechanism used for adjusting the height of the setting belt support frame, wherein a setting belt positioning mechanism is arranged on the setting belt support frame; the setting belt positioning mechanism comprises electromagnetic telescopic cylinders which are arranged in the horizontal direction; each electromagnetic telescopic cylinder comprises a cylinder body and a telescopic rod; the cylinder bodies of the electromagnetic telescopic cylinders are fixedly arranged on the setting belt support frame; the length directions of the telescopic rods point to the middle part of the setting belt support frame; and clamping heads capable of clamping the setting belt are arranged at the end parts of the telescopic rods. According to the quick cement sculpture forming machine, through the arrangement of the setting belt and the vertical driving mechanism used for adjusting the height of the setting belt support frame, cement filling can be performed quickly layer by layer, which is different from the conventional printing mode and can multiply the cement sculpture manufacturing efficiency.
