Fluid food filling machine based on gravity sliding

The invention discloses a fluid food filling machine based on gravity sliding. The fluid food filling machine based on gravity sliding comprises a bottom frame, a long supporting rod, a material barrel and the like. A round hole is formed in one side of the bottom frame; internal threads are arranged in the round hole; the long supporting rod is installed on the bottom frame; the material barrel is installed at the end, away from the bottom frame, of the long supporting rod and used for containing liquid; a small hole is formed in the bottom of the material barrel; and the liquid in the material barrel can be discharged through the small hole. According to the fluid food filling machine based on gravity sliding provided by the invention, through cooperation of a conveying assembly and a filling bottle, the filling bottle slides down by means of self weight through an inclined material receiving plate, and a limiting assembly can be triggered in the process, so that the filled filling bottle slides down, and i
