Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1 As shown in Embodiment 1 of this utility model, an emulsification device for a pre-filled syringe includes an emulsification pump 4. One port of the emulsification pump 4 is connected to a circulation pipe 8, and the other port is connected to a container. In this embodiment, the horizontal port of the emulsification pump 4 is connected to the container, allowing material to flow into the container through the emulsification pump and also allowing material to flow back from the container to the emulsification pump 4. The vertical port of the emulsification pump 4 is connected to the circulation pipe 8, which is bent so that its outlet end communicates with the container. Thus, under the action of the emulsification pump 4, a circulation pipeline is formed, realizing circulating emulsification and improving the emulsification effect.
[0027] Furthermore, such as Figure 1 As shown, an oil inlet assembly is connected to the circulation pipe 8, container, or emulsifying pump 4, allowing silicone oil to enter the circulation pipeline. In this embodiment, the oil inlet assembly is connected to the circulation pipe 8 via an oil inlet pipe.
[0028] Furthermore, such as Figure 1As shown, the circulation pipe 8 or the container or the emulsification pump 4 is provided with a delivery pipe 2 for connecting the ultrasonic rubber plug cleaning machine, through which water is delivered into the emulsification pump 4, and after the emulsification is completed, the emulsification mixture can be delivered back to the ultrasonic rubber plug cleaning machine, facilitating the siliconization of the rubber plug. In this embodiment, the delivery pipe 2 is connected to the circulation pipe 8, and the other end of the delivery pipe 2 is connected to the ultrasonic rubber plug cleaning machine, and water is delivered through the delivery pipe 2 and the lower part of the circulation pipe 8 to the emulsification pump 4 by the ultrasonic rubber plug cleaning machine. Preferably, the water gradually enters the container after entering the emulsification pump 4. After the oil and water are respectively delivered into the circulation pipe through the oil inlet pipe and the delivery pipe 2, the water or oil or water-oil mixture is circulated through the circulation pipe, the container and the emulsification pump by the operation of the emulsification pump 4, so as to circularly emulsify the water-oil mixture, and when the water-oil mixture is used for the siliconization of the rubber plug, the problem of uneven siliconization is avoided. In a preferred embodiment, the ultrasonic rubber plug cleaning machine can be a KJCS-20ES type full-automatic wet ultrasonic rubber plug cleaning machine.
[0029] In addition, in this embodiment, the process of gradually storing the water into the container after the water enters the emulsification pump 4 through the delivery pipe 2 is prior to the emulsification process, so the water inlet process does not conflict with the emulsification process.
[0030] Embodiment 2, which is different from embodiment 1, is as shown in Figure 1 As shown, the oil inlet assembly comprises a silicone oil bucket 12 and a silicone oil metering pump 11 connected to the oil outlet of the silicone oil bucket 12, and the silicone oil metering pump 11 is connected to the circulation pipe 8 through the oil inlet pipe. Under the action of the silicone oil metering pump 11, the silicone oil is input into the circulation pipe 8. In addition, a one-way valve 10 is arranged on the oil inlet pipe to prevent the backflow of oil to the oil inlet assembly. The opening of the one-way valve 10 is opened with the opening of the silicone oil metering pump 11, and is closed with the closing of the silicone oil metering pump 11.

The water can enter the funnel 14 through the emulsifying pump 4, and the water-oil mixture can enter the emulsifying pump 4 from the funnel 14 under the action of the emulsifying pump, and then enter the funnel 14 again through the circulating pipe 8.
[0034] Embodiment 5, which is different from embodiment 4, as shown in Figure 1 As shown, the upper part of the funnel 14 is provided with a high liquid level meter 13, and the low liquid level meter 14 is arranged near the horizontal interface of the interface of the emulsifying pump 4 connected with the funnel 14.

The controller is used for controlling the opening and closing of the conveying valve 7 and the emulsifying valve 9, so that the water feeding process and the emulsification process can be carried out in sequence. After the emulsification is completed, the emulsifying valve 9 can be closed and the conveying valve 7 can be opened by the controller, and the emulsified mixture can be sent back to the ultrasonic rubber plug cleaning machine by the emulsifying pump 4, so that the rubber plug can be siliconized.
