The invention relates to the technical field of background wall manufacturing in image-text manufacturing, and discloses accurate sand blasting and carving background wall manufacturing equipment. A shell is included. A screw is movably connected to the bottom of the shell. The two sides of the screw are movably connected with adjusting rods. A suction channel is fixedly connected in the adjustingrods. The side, away from the adjusting rods, of the suction channel is fixedly connected with a feeding channel. The bottom of the screw is movably connected with a carving box. A guiding groove isfixedly connected in the carving box, and an air conveying rod is fixedly connected to the surface of the guiding groove. The shell is placed on the surface of a tile which is about to be subjected tocarving and sand blasting, a drive component is started to make the screw rotate so that a grinding ball can be driven to work, the grinding ball can be reversely pushed, an air pressure rod is madeto upwards extrude an annular film, the adjusting rods can be pushed and bent, the feeding channel gets close to the part, making contact with the tile, of the grinding ball, and accordingly the effects that sand blasting positioning is accurate, and sand blasting moves along with carving moving are achieved.
