[0042] It should be noted here that: the bottle body is positioned by the positioning groove 12, and in the process of positioning the bottle body, the bottom of the bottle body is against the inclined surface 1303 of the upper limit plate 1302 of each limiting assembly, pushing each limiting plate 1302 to move toward the inner side of the sliding groove 1301 and squeezing the third spring 1304 to deform and generate elastic force, through the elastic force of the third spring 1304, one end of each limiting plate 1302 is pushed against the outside of the bottle body after positioning and placement, and the bottle body after positioning and placement is squeezed and limited, so that the bottle body can be more accurately and stably quantitatively packaged.

[0043] Working principle: during the process of the liquid quantitative filling machine performing the liquid quantitative filling operation on the bottle body, the bottle body is placed on each positioning groove 12 in turn, and the bottle body is positioned by the positioning groove 12. During the process of positioning and placing the bottle body, the bottom of the bottle body abuts against the inclined surface 1303 of the upper limit plate 1302 of each limiting assembly, pushing each limiting plate 1302 to move toward the inner side of the sliding groove 1301 and squeeze the third spring 1304 to deform and generate elastic force. Through the elastic force of the third spring 1304, one end of each limiting plate 1302 is pushed against the outside of the positioned bottle body, and the positioned bottle body is squeezed and limited, so that the bottle body can be more accurately and stably quantitatively filled.

[0044] After each bottle body is positioned and placed, the mounting plate 3 is driven to move downward toward the operating table 101 through the lifting assembly and the second guide assembly. Through the downward movement of the mounting plate 3, one end of the delivery tube 6 connected to the lower end of each mounting tube 201 is inserted into the interior of each bottle body, which is convenient for more stable liquid packaging and delivery. In the process of quantitative liquid packaging, the liquid in the liquid storage box 103 is transported toward the interior of the bottle body through the flexible tube 202 and the mounting tube 201 on each delivery assembly. In the process of transportation, the amount of the transported liquid is monitored in real time through the flow valve 203, which is convenient for quantitative packaging of each bottle. In the process of liquid transportation, the sealing plate 801 is pushed to no longer abut against the lower end of the delivery tube 6 through the squeezing effect of the transported liquid, so that the transported liquid The liquid is transported toward the inside of the bottle body through the gap between the blocking plate 801 and the lower end of the delivery tube 6. During the liquid transportation process, the blocking plate 801 is used to buffer and reduce the pressure of the transported liquid, thereby reducing the speed at which the liquid is transported from the delivery tube 6, and further reducing the bubbles generated inside the liquid storage box 103 during liquid transportation, so that the flow valve 203 can monitor more accurately and ensure the quantitative packaging effect. During the protection process, the filter plate 802 can be driven to slide inside the delivery tube 6 by the adjustment component. Through the sliding of the filter plate 802, the elastic force of the first spring 903 between the filter plate 802 and the blocking plate 801 is adjusted, so that the first spring 903 can pull the blocking plate 801 with different elastic forces, so that the protection component can be used for protection with different protection strengths.

[0045] After the quantitative filling of the interior of the bottle body is completed, the delivery of liquid on the installation tube 201 and the delivery tube 6 is stopped. At this time, the sealing plate 801 is pulled by the pulling component to abut against the lower end of the delivery tube 6. Through the effect of the sealing plate 801 abutting against the lower end of the delivery tube 6, the interior of the delivery tube 6 is isolated and protected, which is convenient for the subsequent quantitative filling of the liquid quantitative filling machine.
