4. A method for quantitative filling of fluid materials, characterized in that: The method of using the fluid material quantitative filling device according to claim 3 for filling comprises the following steps: Step 1: When a filling bottle is transported to the filling position, the second cylinder (412) is started to drive the movable plate (410) to move downward, the movable plate (410) drives the injection pipe (411) to move downward, and the injection pipe (411) drives the outer sleeve (41) to move downward. First, the lower pressure ring (416) at the lower end of the outer sleeve (41) covers the bottle mouth of the filling bottle. During the process of continuing to move downward, the injection pipe (411) gradually moves into the filling bottle. Step 2: by opening the first one-way valve (44), closing the second one-way valve (48), and starting the first cylinder (46) to move upward, a quantitative amount of material enters the inside of the quantitative cylinder (45) through the feeding pipe (43), thereby achieving quantitative feeding; by closing the first one-way valve (44), opening the second one-way valve (48), and starting the first cylinder (46) to move downward, a quantitative amount of material flows out of the quantitative cylinder (45) to the discharge pipe (49), and then enters the injection pipe (49) The liquid flows through the discharge hole (417) into the filling bottle; the second cylinder (412) is then started to drive the movable plate (410) to move upward, and the movable plate (410) drives the injection tube (411) to move upward. First, the injection tube (411) moves upward along the outer sleeve (41). Since the injection tube (411) is in close contact with the outer sleeve (41), the discharge hole (417) on the injection tube (411) can be blocked by the outer sleeve (41); Step 3, when the movable plate (410) moves downward, the movable plate (410) drives the tooth plate (31) to move downward, the tooth plate (31) drives the gear (32) to rotate, and the gear (32) drives the second sealing plate (34) to block the filling bottles transported from the side position to the filling position. When the movable plate (410) moves downward to the set position, the tooth plate (31) moves to the lowest position, and the second sealing plate (34) rotates to a horizontal state to completely block the filling bottles at the filling position; Step 4: After the filling is completed, the movable plate (410) moves upward, the movable plate (410) drives the toothed plate (31) to move upward, the toothed plate (31) drives the gear (32) to rotate, the gear (32) drives the second sealing plate (34) to gradually release the filling bottle at the filling position, and at the same time, the gear (32) drives the first sealing plate (33) to gradually block the subsequent filling bottle on one side of the filling position. When the second sealing plate (34) completely releases the filling bottle at the filling position, the first sealing plate (33) can block the subsequent filling bottle on one side of the filling position. When the movable plate (410) moves upward to the set position, the first sealing plate (33) rotates to a horizontal state to completely block the subsequent filling bottle on one side of the filling position.
