Liquid quantitative canning scale

The utility model relates to a liquid quantitative canning scale, and belongs to the technical field of liquid quantitative canning scales. The liquid quantitative filling scale mainly aims at solving the problems that a filling nozzle of an existing liquid quantitative filling scale is generally the same, so that when the caliber of a filling container is too large, the filling time is too long, the filling efficiency is too low, when the caliber of the filling container is too small, too much liquid is sprayed out at a time, and a small container is prone to toppling over in the filling process. According to the technical scheme, the liquid quantitative canning scale comprises a weighing table, the weighing table is fixedly connected with a supporting sliding rod, and the outer wall of the supporting sliding rod is fixedly connected with a controller. Through the design of the liquid spraying head, the blocking block, the liquid outlet hole, the first screw rod, the movable push rod and other structures, wh
