[0033] The working principle of the sterile powder injection vial vacuum extraction machine in this specific embodiment is as follows: the vial enters the inlet wheel 2 from the inlet track 1. The inlet wheel 2 transfers the vial to the vacuum main plate mechanism 3. After the vial is filled with powder, the vacuum inside the vial is extracted in the vacuum main plate mechanism 3, and the vacuum degree inside the vial is automatically detected. Then it enters the outlet wheel 4. Qualified products go to the outlet track 6 to enter the next process, and unqualified products are rejected to the rejection plate 5.

[0034] The working principle of the vacuum main disk mechanism 3 in this specific embodiment is as follows:

[0035] 1. After the vial enters the vacuum main plate through the inlet wheel 2, the vacuum of the vial holder 3-74 is opened to hold the vial in place.

[0036] 2. As the main shaft continues to rotate, under the action of the lower cam 3-81 and the bottle-closing cam 3-51, the lower sliding sleeve 3-72 and the bottle holder 3-74 are pushed upward by the bottle holder bearing 3-82. At this time, the upper sliding rod 3-62 descends, driving the bottle cover 3-66 downward to cover the vial.

[0037] 3. The rotating spindle continues to rotate. Under the action of the suction stopper cam 3-53, the suction stopper head 3-65 descends, the suction stopper vacuum body 3-67 opens and lifts the rubber stopper, and at the same time the bottle suction vacuum body 3-68 opens. The vacuum degree inside the bottle is detected and recorded so as to reject unqualified products.

[0038] 4. Continue rotating the main shaft. Under the action of the suction stopper cam 3-53, the rubber stopper is fastened, maintaining the vacuum inside the bottle.

[0039] 5. As the main shaft continues to rotate, the bottle holder moves downward and the bottle cover moves upward under the action of the cam. Figure 3 When the vacuum in the bottle holder is broken, the vial enters the dispensing wheel to complete one working cycle.

[0040] The machine in this specific embodiment operates continuously, with 16 stations on the vacuum main plate and a capacity of 300 bottles / minute. This machine can both perform vacuuming and nitrogen purging (filling the powder injection vials with nitrogen).

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
