Wherein, remove bubble agitator head 5 including solid fixed ring 501 with remove bubble needle bar 502, gu fixed ring 501 installs on sleeve pipe 4, remove bubble needle bar 502 and fix on solid fixed ring 501, remove bubble needle bar 502 and be the broach form, gu fixed ring 501 accessible set screw is connected with sleeve pipe 4, convenient to detach, when the filling to the oral liquid filling bottle 18 filling of different bore sizes, removable not equidimension remove bubble agitator head 5.

The oral liquid filling machine further comprises a lifting frame 6, the plurality of filling column heads 1 are fixed on the lifting frame 6 at intervals, the number and the spacing of the filling column heads 1 can be specifically set according to production requirements, and the filling column heads 1 can be fixed into one row as shown in figure 3 or can be arranged into a plurality of rows. The lifting frame 6 is slidably mounted on the guide slide bar 7, the lifting frame 6 is fixedly provided with the lifting push rod 8, the guide slide bar 7 and the lifting push rod 8 are vertically fixed on the fixing frame 19, and the lifting push rod 8 can drive the lifting frame 6 to vertically lift.

In the process of filling the oral liquid, air is mixed in the liquid to form a large amount of bubbles, so that the filling amount is insufficient, the final liquid level in each oral liquid filling bottle 18 is different in height, and in order to eliminate the bubbles generated in the filling process, the filling amount in each oral liquid filling bottle 18 is the same.

In order to further improve the defoaming effect of the defoaming stirring head 5, the defoaming stirring head 5 can also rotate in the defoaming process, and the liquid bubbles are broken up in the rotating process through the comb-tooth-shaped defoaming needle rod 502. Specifically, in the first embodiment of driving the bubble removing stirring head 5 to rotate, a driving mechanism (not shown in the figure) can be arranged on the lifting frame 6 and/or the base body, and the sleeve 4 and the bubble removing stirring head 5 are driven to rotate by the driving mechanism. In a second embodiment, the bubble-removing stirring head 5 is driven to rotate, the filling needle tube 2 is rotatably mounted on the filling column head 1, an impeller (not shown) is fixedly mounted at the inner end of the filling needle tube 2, the filling needle tube 2 is fixedly connected with the casing tube 4, and the impeller and the filling needle tube 2 are driven to rotate by the pressure of the filling material, so that the casing tube 4 and the bubble-removing stirring head 5 are driven to rotate.

As a further improvement of the present invention, in order to reduce the generation of filling bubbles, the air in the oral liquid filling bottle 18 can be reduced as much as possible during filling, therefore, in this embodiment, the upper portion of the seat body 3 is set to be concave, a sealed exhaust chamber 9 is formed between the concave portion of the upper portion of the seat body 3 and the filling column head 1, a gap is reserved between the inner wall of the casing 4 and the outer wall of the filling needle tube 2 to form an exhaust channel 10, the upper end of the casing 4 extends into the exhaust chamber 9, the exhaust channel 10 is communicated with the exhaust chamber 9, one side of the seat body 3 is provided with an exhaust tube 11 communicated with the exhaust chamber 9, the exhaust tube 11 is used for connecting a vacuum pump to pump the air in the bottle, and the air in the bottle can enter the exhaust chamber 9 from the exhaust channel 10 and then be.

When air in the oral liquid filling bottle 18 is pumped and discharged, the filling column cap 1 is required to descend to enable the bottom end of the seat body 3 to be in close contact with the mouth of the oral liquid filling bottle 18.

In addition, because the material conveying pipe 13 is generally of a hose structure, in order to prevent negative pressure generated in the bottle from sucking a part of oral liquid material into the bottle when air is pumped and discharged so as to influence precision errors of subsequent filling amount, in the embodiment, a valve seat 14 is installed on the inner wall of the material filling cavity 101, a valve rod 15 is slidably installed on the valve seat 14, a plug 16 is fixed at the upper end of the valve rod 15, a spring 17 is sleeved on the valve rod 15, the spring 17 is located between the plug 16 and the valve seat 14, the plug 16 is driven by the elastic force of the spring 17 to abut against the inner end of the material feeding hole 102, the plug 16 can be in close fit with the inner end of the material feeding hole 102, and under the action of appropriate elastic force, the plug 16 can prevent negative pressure suction force from sucking the material in the material conveying pipe 13 into the material filling cavity 101 and can also. Meanwhile, the plug 16 can prevent the bottom end of the filling needle tube 2 from generating liquid dropping phenomenon, and prevent pollution and waste. In addition, when filling and injecting materials, the oral liquid body can be pushed to open the plug 16 to finish the material injection as long as the power of a delivery pump of the liquid storage delivery system is adjusted to enable the delivery pressure of the oral liquid body to be greater than the elastic force of the spring 17.

In summary, when the oral liquid filling machine of this embodiment works, the lifting rod 8 drives the lifting rack 6 to descend, so that the rubber pad 12 at the bottom end of the seat body 3 contacts and seals with the oral liquid filling bottle 18, and then the vacuum pump pumps air in the bottle, so that the air enters the exhaust chamber 9 through the sleeve 4 and is then exhausted through the exhaust tube 11. Then the liquid storage and conveying system conveys the oral liquid material into the filling column head 1, the material is injected into the oral liquid filling bottle 18 from the filling needle tube 2, liquid bubbles generated by filling rise to the position of a bottle opening along with the rising of the liquid level of the material in the bottle, and the bubble removing stirring head 5 can eliminate the liquid bubbles at the position of the bottle opening to flatten the liquid level. This oral liquid filling machine only needs quantitative filling can guarantee that the filling volume is the same in each oral liquid filling bottle 18 when the filling, and the oral liquid level height in the bottle is also the same, and the filling is not influenced by the foam, can not cause the material extravagant yet.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
