Specifically, the composition structure and connection relationship of each part are as follows:

[0018] The filling component A includes a liquid separation block 1, a metering block 2, a filling needle fixing block 3, a filling needle 4, a servo motor 5 and an electric cylinder 6. The servo motor 5 is connected to the electric cylinder 6. Guide rails 18 are arranged on both sides of the electric cylinder 6. The electric cylinder 6 and the two guide rails 18 are mounted on a fixing seat 19 by nuts. A slider 20 is slidably arranged on the guide rail 18. The slider 20 is fixedly connected to a fixing plate 21 by nuts. The filling needle fixing block 3 is fixedly connected to the fixing plate 21 by nuts. The filling needle fixing block 3 is locked and connected to the metering block 2 by nuts. The metering block 2 is locked and connected to the liquid separation block 1 by nuts. The filling needle 4 is installed on the filling needle fixing block 3. An air shower chamber B is installed at the bottom of the filling needle fixing block 3. The filling needle 4 is arranged through the air shower chamber B.

[0019] The air shower room B includes an air shower block 7, an air inlet pipe 8 and a flow equalizing plate 9. The air shower block 7 is connected to the bottom of the filling needle fixing block 3 by a nut locking, and the flow equalizing plate 9 is installed on the lower part of the air shower block 7 by a nut locking. The filling needle 4 is arranged through the holes of the air shower block 7 and the flow equalizing plate 9, and the filling needle 4 is located in the middle of the flow equalizing plate 9. The air inlet pipe 8 is also connected and fixed to the air shower block 7 by a nut.

[0020] It is worth noting that a spacer sleeve 22 is provided below the air shower room B. The spacer sleeve 22 is installed on the upper part of the die head 23 by locking with a nut. The spacer sleeve 22 passes through the middle part of the die head 23, and the filling needle 4 is provided through the spacer sleeve 22.

[0021] The air circuit component C includes a filter 10, a filter element 11, a steam valve 12, an air valve 13, a pressure gauge 14, a sanitary hose 15, a temperature probe 16 and a steam trap 17. The filter element 11 is installed inside the filter 10, and the steam valve 12 and the air valve 13 are installed on the upper end pipeline of the filter 10, wherein the steam valve 12 is connected to the steam pipeline, and the air valve 13 is connected to the compressed air pipeline; the filter 10 is installed with a pressure gauge 14, and the lower end pipeline of the filter 10 is installed with a sanitary hose 15, a temperature probe 16 and a steam trap 17, and the sanitary hose 15 is connected to the interface of the air inlet pipe 8 in the air shower room B.

[0022] The working principle of this specific implementation is:

[0023] ① Sterilization: The sterilization process is controlled by the PLC program. When the program is started, the steam valve 12 is opened, and steam enters through the steam pipeline to sterilize the filter 10, the filter element 11, the air shower block 7, and the filling needle 4. During the sterilization process, the temperature is monitored by the temperature probe 16, and the steam temperature is controlled at 121-125°C. The sterilization time is 20 minutes. After the sterilization is completed, the steam valve 12 is closed, and the air valve 13 is opened. Compressed air with a pressure of 1 bar enters through the compressed air pipeline and blows for 20 minutes to dry the filter 10, the air shower block 7, the filling needle 4 and the internal pipeline of the device.

[0024] ② Before production, the servo motor 5 controls the electric cylinder 6 to move upward, and the electric cylinder 6 drives the filling component A and the air shower room B to move upward along the guide rail 18, separating from the spacer 22, and exposing the filling needle body on the upper part of the spacer 22. At the same time, the air valve 13 opens, and the compressed air with a pressure of 1 bar enters the pipeline through the compressed air pipeline, passes through the filter 10, and is sterilized and filtered by the filter element 11 to become sterile gas, which flows to the air shower block 7. The sterile gas is blown out through the flow equalizing plate 9, and the sterile gas protects the exposed filling needle 4 from being contaminated by the outside air. During the production process, the electric cylinder 6 drives the filling component A to move up and down, and the exposed filling needle body is also protected by the sterile gas blown out by the flow equalizing plate 9 and is not contaminated.

[0025] This specific implementation can protect the filling needle from being contaminated during the up and down movement of the filling needle, is reliable and practical, and has broad market application prospects.
