Filling machine frame with two-dimensional limit function

The utility model discloses a filling machine frame with a two-dimensional limit function. The filling machine frame can easily and quickly fix material guns during material gun replacement. The filling machine frame comprises a main frame body and a rotating swing arm formed by connecting two sections of connecting rods with a linear guide rail through middle shafts and bolts. A material gun assembly is formed by connecting a material gun with a material gun connecting plate through bolts. The material gun connecting plate and a frame connecting plate are both of a Z-shaped structure. A square or round hole, a bolt hole, a fabrication hole and a groove are formed in the middle portion of the material gun connecting plate. An insertion bolt, a bolt hole, a fabrication hole and a boss are formed in the middle portion of the frame connecting plate. When the material gun connecting plate and the frame connecting plate are combined, the V-shaped groove is in combination with the V-shaped boss to limit the displacement in the horizontal direction, and the rectangular bolt is matched with the square hole to limit the displacement in the vertical direction. The filling machine frame with the two-dimensional limit function can be provided with a plurality of material guns for achieving filling of multiple materials, thereby improving the utilization and compatibility and enhancing the market competitiveness of an enterprise.
