AI Technical Summary
In existing dispensing devices, freeze-dried microspheres tend to fall out of the same dispensing hole, resulting in poor dispensing performance.
A freeze-dried microsphere filling device is adopted, which includes a filling table and a sieving assembly. The diameter of the sieving hole is larger than the diameter of the microsphere but the depth is smaller than the diameter of the microsphere. The microspheres are made to enter the sieving hole by shaking the filling table. The baffle and sliding plate structure ensures that only one microsphere falls into each filling hole.
This improves the dispensing effect of freeze-dried microspheres, ensuring that only one microsphere falls out of each dispensing hole, reducing microsphere waste and inaccurate dispensing.

Abstract
Description
Technical Field
[0001] This application relates to the field of biological experimental equipment, and in particular to a dispensing device for freeze-dried microspheres. Background Technology
[0002] In many fields such as biopharmaceuticals and biodetection, it is often necessary to use dispensing devices to accurately dispense lyophilized microspheres for subsequent experimental operations or product packaging.
[0003] In related technologies, the dispensing device includes a dispensing platform with multiple dispensing holes evenly spaced on it. A receiving plate is positioned at the bottom of the dispensing platform and has multiple receiving holes aligned with the dispensing holes to receive freeze-dried microspheres falling from them. In use, the operator places the freeze-dried microspheres on the dispensing platform and then shakes the platform to cause the microspheres to fall from the dispensing holes into the receiving holes, thus dispensing the freeze-dried microspheres.
[0004] However, in practical applications, multiple freeze-dried microspheres tend to fall out of the same dispensing hole, resulting in poor dispensing effect of freeze-dried microspheres, which requires improvement. Utility Model Content
[0005] To improve the dispensing effect of freeze-dried microspheres, this application provides a dispensing device for freeze-dried microspheres.
[0006] The freeze-dried microsphere packaging device provided in this application adopts the following technical solution:
[0007] A dispensing device for freeze-dried microspheres includes a dispensing platform and a sieving assembly. The dispensing platform has a plurality of dispensing holes evenly distributed on it. The sieving assembly includes a sieving plate and a baffle. The sieving plate is slidably connected to the dispensing platform, located above the dispensing holes and having a plurality of sieving holes, with each sieving hole offset from the dispensing hole. The baffle is located on the upper side of one end of the sieving plate. The diameter of each sieving hole is larger than the diameter of the freeze-dried microspheres, and the depth of each sieving hole is smaller than the diameter of the freeze-dried microspheres.
[0008] By adopting the above technical solution, in practical applications, multiple freeze-dried microspheres are placed on the upper side of the sieving plate. The baffle blocks the freeze-dried microspheres to prevent them from falling between the dispensing table and the sieving plate as much as possible. By shaking the dispensing table, the freeze-dried microspheres fall into the sieving holes. Since the diameter of the sieving holes is larger than the diameter of the freeze-dried microspheres, and the depth of the sieving holes is smaller than the diameter of the freeze-dried microspheres, only one freeze-dried microsphere can be placed in each sieving hole. The remaining freeze-dried microspheres are shaken to the baffle, and then the sieving plate is slid to align each sieving hole with each dispensing hole, ensuring that only one freeze-dried microsphere falls into each dispensing hole, thereby improving the dispensing effect of the freeze-dried microspheres.
[0009] Preferably, the two inner sides of the dispensing table are provided with slots along their own length, and the screening plate is inserted into the two slots.
[0010] By adopting the above technical solution, and by setting slots, the screening plate is inserted into two slots to achieve the sliding connection of the screening plate to the dispensing table.
[0011] Preferably, the dispensing table is further provided with a positioning groove, which is connected to one end of the two slots near the baffle, and the baffle abuts against the groove wall of the positioning groove.
[0012] By adopting the above technical solution, and by setting a positioning groove, the baffle abuts against the groove wall to achieve positioning of the baffle, which ensures that each screening hole and each dispensing hole are misaligned.
[0013] Preferably, the screening assembly further includes two mounting blocks and a partition. The two mounting blocks are disposed on the upper side of the screening plate, and the partition is inserted vertically into the two mounting blocks and located on the side of the baffle close to the screening hole.
[0014] By adopting the above technical solution, by setting two mounting blocks and a partition, the partition slides vertically so that it abuts against the upper side of the screening plate, thereby confining multiple freeze-dried microspheres between the partition and the baffle, further improving the packaging effect of freeze-dried microspheres.
[0015] Preferably, the screening assembly further includes two guide plates, which are disposed on the upper side of the screening plate, with one end of each guide plate abutting against the mounting block and the other end abutting against the baffle.
[0016] By adopting the above technical solution and setting two guide plates, the freeze-dried microspheres can be passed between the two mounting blocks as much as possible, so that the freeze-dried microspheres can fall into the sieve hole.
[0017] Preferably, the screening assembly further includes a pusher plate and a sliding rod, the pusher plate being located between the baffle and the partition, and the sliding rod being disposed on the side of the pusher plate near the baffle and movably passing through the baffle.
[0018] By adopting the above technical solution, and by setting a pusher plate and a sliding rod, the sliding rod can be moved so that the pusher plate can push the freeze-dried microspheres through the two mounting blocks so that the freeze-dried microspheres can fall into the sieve hole.
[0019] Preferably, the screening assembly further includes a handle located at the end of the sliding rod away from the push plate.
[0020] By adopting the above technical solution and setting a handle, the sliding rod can be moved easily.
[0021] Preferably, the screening assembly further includes a connecting block, which is disposed on the side of the baffle near the partition. The upper side of the connecting block is inclined, and the upper side of the connecting block near the baffle is higher than the upper side of the other end. The partition has a connecting groove in the vertical direction, and the connecting block is movably inserted through the connecting groove and its upper side abuts against the bottom wall of the connecting groove.
[0022] By adopting the above technical solution, by setting a connecting block and sliding the sliding rod, the push plate is brought close to the partition. With the cooperation of the connecting block and the connecting groove, the partition can move automatically upward to remove the obstruction to the freeze-dried microspheres, thereby facilitating the push of the freeze-dried microspheres into the sieve hole.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By shaking the dispensing table, the freeze-dried microspheres fall into the sieve holes. Since the diameter of the sieve holes is larger than the diameter of the freeze-dried microspheres and the depth of the sieve holes is smaller than the diameter of the freeze-dried microspheres, only one freeze-dried microsphere can be placed in each sieve hole. The remaining freeze-dried microspheres are shaken to the baffle, and then the sieve plate is slid to align each sieve hole with each dispensing hole, which can ensure that only one freeze-dried microsphere falls into each dispensing hole, thereby improving the dispensing effect of freeze-dried microspheres.
[0025] 2. By setting two mounting blocks and a partition, the partition slides vertically so that it abuts against the upper side of the screening plate, thereby confining multiple freeze-dried microspheres between the partition and the baffle, further improving the packaging effect of the freeze-dried microspheres;
[0026] 3. By setting a connecting block and sliding the sliding rod, the push plate is brought close to the partition. With the cooperation of the connecting block and the connecting groove, the partition can move automatically upward to remove the obstruction to the freeze-dried microspheres, thus making it easier to push the freeze-dried microspheres into the sieve hole.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a dispensing device for freeze-dried microspheres.
[0034] Example 1:
[0035] Reference Figure 1 and Figure 2 The dispensing device includes a dispensing platform 1, a screening component 2, and a receiving plate 3. The dispensing platform 1 is evenly provided with a plurality of dispensing holes 11. In this embodiment, the number of dispensing holes 11 is 96.
[0036] Specifically, the screening component 2 includes a screening plate 21 and a baffle 22. The screening plate 21 is a rectangular plate, which is slidably connected to the dispensing table 1 in the direction of its length. The screening plate 21 is located above the dispensing holes 11 and has multiple screening holes 211. The number of screening holes 211 is the same as the number of dispensing holes 11, and each screening hole 211 is offset from each dispensing hole 11. The baffle 22 is also a rectangular plate and is fixedly connected to the upper side of one end of the screening plate 21. The diameter of the screening holes 211 is slightly larger than the diameter of the freeze-dried microspheres, and the depth of the screening holes 211 is smaller than the diameter of the freeze-dried microspheres. The receiving plate 3 is positioned and installed on the dispensing table 1 by snap-fit. The receiving plate 3 is located below the dispensing holes 11, and each receiving hole (not marked in the figure) on the receiving plate 3 is aligned with each dispensing hole 11.
[0037] In practical applications, multiple freeze-dried microspheres are placed on the upper side of the sieve plate 21, and the baffle 22 blocks the freeze-dried microspheres to prevent them from falling between the dispensing table 1 and the sieve plate 21. By shaking the dispensing table 1, the freeze-dried microspheres fall into the sieve holes 211 because the sieve holes 211 and dispensing holes 11 are misaligned. Simultaneously, the diameter of the sieve holes 211 is larger than the diameter of the freeze-dried microspheres, and the depth of the sieve holes 211 is smaller than the diameter of the freeze-dried microspheres, ensuring that only one freeze-dried microsphere is placed in each sieve hole 211. The remaining freeze-dried microspheres are then shaken to the baffle 22, and the sieve plate 21 is slid to align each sieve hole 211 with each dispensing hole 11, thus ensuring that only one freeze-dried microsphere falls into each dispensing hole 11, thereby improving the dispensing effect of the freeze-dried microspheres. It should be noted that the dispensing holes 11 are larger than the sieve holes 211 to facilitate the falling of the freeze-dried microspheres.
[0038] In some embodiments, slots 12 are provided on both inner sides of the dispensing platform 1. The slots 12 are arranged along the length of the dispensing platform 1. The two sides of the sieving plate 21 are respectively inserted into the two slots 12 to realize the slidable connection of the sieving plate 21 to the dispensing platform 1. The structure is simple and the operation is convenient.
[0039] In some embodiments, the dispensing table 1 is also provided with a positioning groove 13. The positioning groove 13 is connected to one end of the two slots 12 near the baffle 22, and the baffle 22 abuts against the groove wall of the two positioning grooves 13, so as to realize the positioning of the baffle 22. At this time, it can be ensured that each screening hole 211 is misaligned with each dispensing hole 11, thereby ensuring that only one freeze-dried microsphere falls out of each dispensing hole 11.
[0040] The implementation principle of this embodiment is as follows: In practical applications, multiple freeze-dried microspheres are placed on the upper side of the sieve plate 21, and the baffle 22 blocks the freeze-dried microspheres to prevent them from falling between the dispensing table 1 and the sieve plate 21 as much as possible. By shaking the dispensing table 1, the freeze-dried microspheres fall into the sieve holes 211 because the sieve holes 211 are misaligned with the dispensing holes 11. At the same time, the diameter of the sieve holes 211 is larger than the diameter of the freeze-dried microspheres, and the depth of the sieve holes 211 is smaller than the diameter of the freeze-dried microspheres, so that only one freeze-dried microsphere is placed in each sieve hole 211. Then, the remaining freeze-dried microspheres are shaken to the baffle 22, and the sieve plate 21 is slid to align each sieve hole 211 with each dispensing hole 11, thus ensuring that only one freeze-dried microsphere falls into each dispensing hole 11, thereby improving the dispensing effect of the freeze-dried microspheres. It should be noted that the dispensing hole 11 is larger than the sieve hole 211 to facilitate the dropping of freeze-dried microspheres.
[0041] Example 2:
[0042] Reference Figure 3 and Figure 4 This embodiment is identical to Embodiment 1 in all other structural aspects, except that the screening assembly 2 further includes two mounting blocks 23 and a partition 24. The two mounting blocks 23 are fixedly connected to the upper side of the screening plate 21, and are located between the screening hole 211 and the baffle 22. The partition 24 is vertically inserted into the two mounting blocks 23, allowing it to move vertically. When the freeze-dried microspheres fall into the screening hole 211, the partition 24 moves upward, allowing the freeze-dried microspheres to pass between the two mounting blocks 23 and the partition 24. Moving the partition 24 downward, so that it abuts against the screening plate 21, prevents other freeze-dried microspheres from falling back into the screening hole 211 during the process of the freeze-dried microspheres falling through the dispensing hole 11 onto the receiving plate 3, thereby further improving the dispensing effect of the freeze-dried microspheres.
[0043] In some embodiments, the screening assembly 2 further includes two guide plates 25, which are fixedly connected to the upper side of the screening plate 21. One end of the guide plate 25 abuts against the mounting block 23, and the other end abuts against the baffle 22. The guide plate 25 is flush with the end of the mounting block 23 away from the dispensing table 1. This reduces the accumulation of freeze-dried microspheres between the mounting block 23 and the dispensing table 1, thus ensuring that the freeze-dried microspheres can pass between the two mounting blocks 23 as much as possible, so that the freeze-dried microspheres can fall into the screening hole 211.
[0044] In some embodiments, the screening assembly 2 further includes a push plate 26 and a sliding rod 27. The push plate 26 is located between the baffle 22 and the partition 24. The sliding rod 27 is fixedly connected to the side of the push plate 26 near the baffle 22 and is movably inserted through the baffle 22. By sliding the sliding rod 27, the push plate 26 can push the freeze-dried microspheres through the two mounting blocks 23 so that the freeze-dried microspheres can fall into the screening hole 211.
[0045] In some embodiments, the screening assembly 2 further includes a handle 28, which is fixedly connected to the end of the sliding rod 27 away from the push plate 26 to facilitate the application of force and thus facilitate the sliding of the sliding rod 27. Furthermore, the sliding rod 27 is threadedly connected to the push plate 26, enabling the overall installation and disassembly of the screening assembly 2.
[0046] In some embodiments, the screening assembly 2 further includes a connecting block 29, which is fixedly connected to the side of the baffle 22 near the partition 24. The upper side of the connecting block 29 is inclined, and the upper side of the connecting block 29 near the baffle 22 is higher than the upper side of the other end. Meanwhile, the partition 24 has a connecting groove 241 in a vertical direction, and the connecting block 29 is movably inserted through the connecting groove 241 with its upper side abutting against the top wall of the connecting groove 241. Thus, by sliding the sliding rod 27, the push plate 26 moves closer to the partition 24. With the cooperation of the connecting block 29 and the connecting groove 241, the partition 24 can automatically move upward to release the obstruction of the freeze-dried microspheres, thereby facilitating the pushing of the freeze-dried microspheres into the screening holes 211. In this embodiment, there are two connecting blocks 29 and two connecting grooves 241 to stably drive the partition 24 upward.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
