The present invention relates to a liquid quantitative injection device having a relatively simple configuration installed in an automatic packaging machine, which is much smaller than the volume of the main tank but is two to three times larger than the bag volume at the lower portion of the main tank installed at the upper portion of the automatic packaging machine. By installing a large volume of auxiliary tank so that the juice of the main tank is always supplied to the bag through the auxiliary tank less affected by gravity, a certain amount of juice is injected into the bag without error, the packaging machine for automatic juicer (4) The main tank 10 having a relatively large volume installed at the upper part of the base 8, the auxiliary tank 6 provided at the lower part of the main tank 10, and the liquid of the main tank 10; Supply pipe 12 to be supplied to (6), the injection pipe 16 for injecting the juice of the auxiliary tank 6 into the bag 14, the flow path of the supply pipe 12 and the injection pipe 16 ) Opening and closing flow path opening and closing means (18) and (20), respectively, It will largely configured the juice height (liquid level) supplied to the 12 to the liquid level to automatically adjust (液體 位置) adjusting means, and a controller (C).;The inner volume of the auxiliary tank is formed to be 2 to 3 times larger than the volume of the bag so as to always retain the juice that can be injected into the bag, the inner diameter of the supply pipe installed in the main tank of the injection pipe installed in the auxiliary tank 1.2 to 2 times larger than the inner diameter to ensure that the juice of the main tank is smoothly supplied to the auxiliary tank.
