The oil storage tank 5 is used to store the edible vegetable oil to be filled. It should be noted that the oil storage tank 5 can be connected through an external oil supply pipeline to continuously supply the edible vegetable oil to the oil storage tank 5 to avoid filling interruption caused by untimely supply;

[0042] The lifting assembly 6 is arranged on the top of the filling frame 3, and the plurality of quantitative filling assemblies 7 are respectively connected to the lifting assembly 6. The bottle clamping assembly 4 is arranged on the bottom of the filling frame 3 to clamp the oil bottle on the conveying device 1 to prevent the oil bottle from tilting during filling, thereby affecting the filling effect.

[0043] The lifting assembly 6 is used to adjust the height of the quantitative filling assembly 7, and the quantitative filling assembly 7 is connected to the oil storage tank 5 so as to fill the edible vegetable oil in the oil storage tank 5 into the oil bottle clamped by the bottle clamping assembly 4; when the oil bottle is transported to the bottom of the filling rack 3, the lifting assembly 6 can drive the quantitative filling assembly 7 to descend to realize the vegetable oil filling of the oil bottle.

[0044] like Figure 4 and Figure 5As shown, the quantitative filling assembly 7 includes a first cylinder 71, an oil filling cylinder 72, a piston body (not shown), a second cylinder 73 and a rotary valve 74. The side wall of the oil filling cylinder 72 is connected to the oil storage tank 5 through a hose 75. The oil filling cylinder 72 has an inner chamber for accommodating edible vegetable oil. The piston body is arranged in the inner chamber, and its top is connected to the first cylinder 71.

By adjusting the locking knob 24, the position of the straight rod portion 221 of the clamping rod 22 in the clamping hole 230 can be changed, thereby adjusting the distance between the gear bars on both sides to accommodate oil bottles of different diameters.

[0051] like Figure 1 As shown, further, the number of the quantitative filling components 7 is four. In this embodiment, the filling mechanism can simultaneously fill four oil bottles with vegetable oil at one time.
