[0037] A pulling mechanism 6 is provided on the side of the tray 3 close to the lifting mechanism 2, and the pulling mechanism 6 includes a pulling cylinder 61, which is fixedly connected to the side of the inner cavity of the tray 3 away from the storage mechanism 4, and a gear 62 is movably connected to the outer side of the pulling cylinder 61, and a pull rod 63 is fixedly connected to the side of the gear 62 close to the pulling cylinder 61, and the pull rod 63 is fixedly connected to the pull rope 46, and the pull rod 63 is movably connected to the inner cavity of the pulling cylinder 61, and racks 64 are fixedly connected on both sides of the inner cavity of the support frame 26 close to the gear 62, and the gear 62 is meshed with the rack 64.

[0038] The soft cushion 53 is located above the tray 3 , and the portion of the pull rope 46 away from the pulling cylinder 61 is located between the tray 3 and the soft cushion 53 .

[0039] The spring assembly 51 is composed of a return spring 511 and a damping lifting rod 512 . The damping lifting rod 512 is located at the center of the inner cavity of the return spring 511 . The tops of the return spring 511 and the damping lifting rod 512 are fixedly connected to the lower pressure plate 52 .

[0040] The two sides of the tray 3 close to the rack 64 are fixedly connected with the limit bars 9 . When the tray 3 is located in the inner cavity of the support frame 26 , the limit bars 9 are in contact with the upper part of the inner cavity of the support frame 26 .

[0041] The part of the storage rod 44 located in the inner cavity of the storage cylinder 41 is fixedly connected to the freeze-dried protective bag 45, and the part of the storage rod 44 located in the inner cavity of the coil spring cylinder 42 is fixedly connected to the reset coil spring 43. The top of the tray 3 near the pulling mechanism 6 and both sides of the storage mechanism 4 are movably connected with rollers 7, and the freeze-dried protective bag 45 and the pull rope 46 are both attached to the surface of the roller 7. The top of the tray 3 near the storage mechanism 4 is fixedly connected with a scraper 8, and the top of the scraper 8 is attached to the freeze-dried protective bag 45.

[0042] The working principle and beneficial effects of the above technical solution are as follows: the spleen aminopeptide concentrate is injected into the vial, and the bottle stopper is inserted on the top of the vial, but not completely closed, so as to facilitate freeze-drying of the material in the vial to evaporate the moisture of the material, and then the vial is stacked in the inner cavity of the tray 3, and then the limiting strip 9 is aligned with both sides of the inner cavity of the support frame 26, and the tray 3 is placed in the inner cavity of the support frame 26;

[0043] When the tray 3 is pushed into the inner cavity of the support frame 26, the gear 62 is meshed with the rack 64, thereby driving the gear 62 to rotate. When the gear 62 rotates, the pull rod 63 is driven to rotate, thereby pulling the pull rope 46 through the pull cylinder 61 through the pull rod 63 to be wound around the surface of the pull rod 63 and stored in the inner cavity of the pull cylinder 61;

[0044] When the pull rope 46 moves, the freeze-dried protective bag 45 is pulled out from the inner cavity of the storage tube 41. When the freeze-dried protective bag 45 moves, the storage rod 44 is driven to rotate, thereby driving the return coil spring 43 to contract, and the freeze-dried protective bag 45 covers the top of the tray 3 to protect the vials in the inner cavity of the tray 3. In the process of the staff pushing the tray 3, the freeze-dried protective bag 45 is automatically used to protect the materials in the inner cavity of the tray 3, so that the staff no longer needs to put on the freeze-dried protective bags 45 one by one, which greatly improves the work efficiency;

[0045] As the tray 3 continues to move toward the inner cavity of the lifting mechanism 2, when the tray 3 is completely located in the inner cavity of the support frame 26, the lower pressing block 55 contacts and presses the protrusion 54, driving the lower pressing plate 52 to move downward. Since the freeze-dried protective bag 45 is located between the soft cushion 53 and the tray 3, the soft cushion 53 is driven to press and fix the freeze-dried protective bag 45, compact and seal the freeze-dried protective bag 45 and the tray 3, and through the deformability of the soft cushion 53, it is ensured that the freeze-dried protective bag 45 is completely sealed and pressed to avoid air leakage, and ensure that after the freeze-dried protective bag 45 is automatically laid, the tray 3 and the freeze-dried protective bag 45 are also sealed to avoid flying powder;

[0046] The freeze-drying protective bag 45 is water-permeable and air-permeable, and the model used is the Taikelun freeze-drying bag.

[0047] Embodiment 2: Figures 1 to 4 As shown, an embodiment of the present invention provides a freeze-drying device for producing spleen aminopeptide freeze-dried powder, the lifting mechanism 2 also includes a cylinder 21, the cylinder 21 is fixedly connected to the top of the freeze-drying mechanism 1, the output end of the cylinder 21 is fixedly connected to a top plate 22, the top plate 22 and the bottom ends of the support frame 26 are fixedly connected to a pressing plate 23, both sides of the top plate 22 are fixedly connected to rings 24, and both sides of the support frame 26 are fixedly connected to lifting rod assemblies 25.

[0048] The lifting rod assembly 25 is composed of a plurality of lifting rods of different lengths. There are a plurality of support frames 26 , and the plurality of support frames 26 are movably connected to the collar 24 through the lifting rod assembly 25 .

[0049] The working principle and beneficial effects of the above technical solution are as follows: the freeze-drying mechanism 1 performs freeze-drying processing on the material in the inner cavity of the tray 3. During the processing, the top plate 22 of the inner cavity of the freeze-drying mechanism 1 is sleeved on the top of the lifting rod assembly 25 through the sleeve ring 24, and multiple support frames 26 are lifted and suspended in the inner cavity of the freeze-drying mechanism 1. When the processing is completed, the cylinder 21 is started to drive the top plate 22 to descend, and the sleeve ring 24 is driven to descend by the descent of the top plate 22. First, the sleeve ring 24 descends along the longest lifting rod assembly 25 fixedly connected to the lowest support frame 26, and the lowest support frame 26 contacts the bottom end of the inner cavity of the freeze-drying mechanism 1 and stops moving. Then the penultimate support frame 26 falls on the top of the lowest support frame 26, and so on, so that the support frames 26 in the inner cavity of the freeze-drying mechanism 1 descend from bottom to top by their own gravity, and then the pressing plate 23 presses the material in the inner cavity of the tray 3, thereby compacting the bottle stopper on the top of the vial;

[0050] Next, the freeze-drying mechanism 1 is opened to take out the tray 3 and the inner cavity of the support frame 26. When the tray 3 moves toward the outside of the support frame 26, the lower pressing block 55 separates from the protrusion 54, so that the tension of the spring assembly 51 drives the lower pressing plate 52 to move upward, so that the soft cushion 53 is separated from the freeze-drying protective bag 45.

[0051] Then, the pull rope 46 is released by rotating the pull rod 63. At this time, the reset coil spring 43 loses its limit and drives the storage rod 44 to rotate through its own elasticity, thereby pulling the freeze-dried protective bag 45 back into the inner cavity of the storage tube 41. In the process of pulling back the freeze-dried protective bag 45, the scraper 8 is used to scrape off the dust that may be contaminated on the bottom of the freeze-dried protective bag 45.

[0052] Working principle and use process: Place spleen aminopeptide concentrate in a vial, and the stopper of the vial is not completely closed, then place the vial in the inner cavity of the tray 3, and then mesh the gear 62 with the rack 64, and push the limit bar 9 into the inner cavity of the support frame 26 along the inner wall of the support frame 26. During the pushing process, the gear 62 and the rack 64 mesh, thereby driving the pull rod 63 to rotate and pull the pull rope 46 into the inner cavity of the pulling cylinder 61 and wrap around the surface of the pull rod 63;

[0053] The pull rope 46 pulls the freeze-dried protective bag 45 out of the inner cavity of the storage tube 41. When the freeze-dried protective bag 45 is pulled out, the storage rod 44 is driven to rotate, thereby driving the return coil spring 43 to contract, and then the freeze-dried protective bag 45 is covered on the top of the tray 3 and located below the soft cushion 53, and the freeze-dried protective bag 45 protects the material in the inner cavity of the tray 3;

[0054] When the tray 3 drives the protrusion 54 to move to the middle of the inner cavity of the support frame 26, the lower pressing block 55 contacts the protrusion 54 and presses the protrusion 54 downward, thereby driving the cushion 53 at the bottom of the lower pressing plate 52 to descend and press and seal the freeze-dried protective bag 45 covering the top of the tray 3;

[0055] Then, the freeze-drying mechanism 1 freezes and dries the material. After the freeze-drying process is completed, the cylinder 21 is started to drive the top plate 22 and the collar 24 to descend. First, the collar 24 descends along the longest lifting rod assembly 25 fixedly connected to the lowest support frame 26. The lowest support frame 26 contacts the bottom end of the inner cavity of the freeze-drying mechanism 1 and stops moving. Then, the second-to-last support frame 26 falls on the top of the lowest support frame 26. Similarly, the support frames 26 in the inner cavity of the freeze-drying mechanism 1 descend from bottom to top in sequence by their own gravity, thereby reducing the spacing between the support frames 26, so that the pressing plate 23 is pressed down to cover the top of the vial in the inner cavity of the tray 3, and the bottle stopper on the top is pressed down.

[0056] After the processing is completed, the staff takes out the tray 3. At this time, the gear 62 and the rack 64 are engaged, thereby driving the pull rope 46 on the surface of the pull rod 63 to release the inner cavity of the pulling cylinder 61, and the reset coil spring 43 drives the storage rod 44 to reset, so that the freeze-dried protective bag 45 is stored and recovered in the inner cavity of the storage cylinder 41. At this time, the dust at the bottom of the freeze-dried protective bag 45 is scraped off through the top of the limiting strip 9, and the scraped dust remains in the inner cavity of the tray 3.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
