Technical Field

[0001] This utility model relates to the field of drug production and recycling technology, specifically a defective tablet separation device. Background Technology

[0002] Tablets are solid dosage forms, typically in the shape of tablets or irregularly shaped tablets, which are formed by uniformly mixing a drug with excipients and then compressing them. They are primarily used for oral administration. Their core components include the active pharmaceutical ingredient (API) and excipients, such as fillers, binders, and disintegrants.

[0003] In the compression production process of tablet drugs, tablets may break during compression. These broken tablets are called defective tablets. Since the tablets break into defective products of different sizes, they need to be separated and classified according to size when recycling them. Traditionally, tablet drugs are mostly sorted and sieved manually. This method greatly increases the labor intensity of workers and the cost of human resources. At the same time, the separation and screening efficiency is low and the overall practicality is not strong. Therefore, this utility model proposes a defective tablet separation device.

[0024] Please see Figure 1-4The present invention provides an embodiment of a defective tablet separation device, comprising a separation body 1, a separation chamber 2 inside the separation body 1, and a primary sieve plate 3, a secondary sieve plate 4, a tertiary sieve plate 5 and a material support plate 6 respectively installed from top to bottom inside the separation chamber 2. The primary sieve plate 3, the secondary sieve plate 4, the tertiary sieve plate 5 and the material support plate 6 are arranged at equal intervals. The primary sieve plate 3, the secondary sieve plate 4 and the tertiary sieve plate 5 are all provided with sieve filter holes 7. The diameter of the sieve filter holes 7 of the primary sieve plate 3, the secondary sieve plate 4 and the tertiary sieve plate 5 gradually decreases from top to bottom.

[0025] With this structural design, when it is necessary to separate defective tablets, the tablets can be placed uniformly on the top primary sieve plate 3. At this time, the defective tablets on the primary sieve plate 3 can fall through the sieving holes 7 of each sieve plate by gravity, thus completing the multi-stage sieving of defective tablets. The defective drugs can be separated and sieved according to size. The largest tablets will remain on the primary sieve plate 3, the second-sized tablets will remain on the second-sized sieve plate 4, the third-sized tablets will remain on the third-sized sieve plate 5, and the smallest tablets will remain on the support plate 6. In this way, the defective tablet separation and sieving work can be completed through the multi-stage sieve plates.

[0026] In this embodiment, to better and more quickly separate the defective tablets, please refer to the appendix of the instruction manual for details. Figure 2 as well as Figure 4 As shown, an upper end cover 8 is fixedly installed on the top surface of the separator 1. A rotary motor 9 is fixedly installed at the center of the upper surface of the upper end cover 8. The output shaft of the rotary motor 9 is inserted into the interior of the separation chamber 2 and is fixedly connected to a central shaft. The central shaft passes through the primary screening plate 3, the secondary screening plate 4, the tertiary screening plate 5, and the material support plate 6. The central shaft is connected to the primary screening plate 3, the secondary screening plate 4, the tertiary screening plate 5, and the material support plate 6 through bearings.

[0027] Furthermore, several mixing rods 10 are fixedly installed inside the primary screening plate 3, the secondary screening plate 4, and the tertiary screening plate 5, and on the outer wall of the central axis.

[0028] This structural design allows the rotary motor 9 to drive the central shaft to rotate via its output shaft. When the central shaft rotates, it drives the mixing rods 10 on each screening plate to rotate. As the mixing rods 10 rotate, they can move the defective tablets on the corresponding screening plates. By mixing and driving the defective tablets, it is possible to effectively prevent them from accumulating statically on the screening plates, thereby improving the separation quality and screening speed, avoiding the phenomenon of material not being discharged after accumulation, and ensuring the normal use of the separation device of this utility model.

[0029] In this embodiment, in order to further improve the overall separation and feeding speed of defective tablets and improve the screening efficiency, a vibration motor 11 is fixedly installed at the center of the lower surface of the bottom of the separator 1. The vibration motor 11 can drive each screening plate to vibrate. In actual use, it has a good vibration screening and feeding effect, which can effectively improve the feeding and separation speed of the separation device of this utility model. It has the practical use characteristics of vibration separation and is more practical.

[0030] In this embodiment, to reduce the ground transmission effect of the vibration motor 11, please refer to the appendix of the specification for details. Figure 2 As shown, spring dampers 12 are fixedly installed at the four corners of the lower surface of the separator 1, and a lower base 16 is fixedly installed between the bottom ends of several spring dampers 12.

[0031] The spring damper 12 is a mature existing technology product. It is composed of a damper and a spring. The working principle of the spring damper 12 is to consume vibration energy by converting mechanical energy into other forms of energy, thereby suppressing vibration. When used in this utility model, the spring damper 12 can effectively reduce the vibration transmission effect of the vibration motor 11 to the lower base 16, thereby effectively helping the machine body to reduce vibration and reducing the transmission influence of the vibration motor 11 to the external ground, and has a certain ground vibration reduction effect.

[0032] In this embodiment, in order to facilitate the sealing of the separation chamber 2 and the observation of the working process, a sealing door 13 is provided on the outside of the separation chamber 2. The sealing door 13 is hinged to the separation machine body 1. A visualization window 14 is provided on the sealing door 13. Transparent tempered glass is installed inside the visualization window 14. A handle 15 is fixedly installed on the outer wall of the sealing door 13. In this way, the internal processing of the machine can be observed through the visualization window 14, which facilitates timely observation and processing.

[0033] Working principle: When using this utility model, the defective tablets of uneven size can be placed uniformly on the top primary sieve plate 3, then the sealing door 13 is closed, and the rotary motor 9 and the vibration motor 11 are started at the same time.

[0034] The rotary motor 9 can drive the central shaft to rotate through its output shaft. When the central shaft rotates, it will drive the mixing rods 10 on each screening plate to rotate. When the mixing rods 10 rotate, they can drive the defective tablets on the corresponding screening plate to move. By mixing the defective tablets, it can effectively prevent them from standing still and accumulating on the screening plate, improve the separation quality and screening speed, avoid the phenomenon of no material discharge after accumulation, and ensure the normal use of the separation device of this utility model.

[0035] By driving each screening plate to vibrate through the vibration motor 11, it has a good vibration screening and feeding effect in actual use, which can effectively improve the feeding and separation speed of the separation device of this utility model and has the practical application characteristics of vibration separation.

[0036] When the rotary motor 9 and the vibration motor 11 are working, the defective drugs on the primary sieve plate 3 can move under the action of the two driving structures. The moving defective drugs can fall through the sieve filter holes 7 of each sieve plate by gravity, thereby completing the multi-stage sieve work of defective tablets, so that the defective drugs can be separated and sieved in multiple stages according to their size.

[0037] After separation and sieving, the largest tablets remain on the primary sieve plate 3, the second-sized tablets remain on the secondary sieve plate 4, the third-sized tablets remain on the tertiary sieve plate 5, and the smallest tablets remain on the support plate 6. In this way, the defective tablet drugs can be separated and sieved through the multi-stage sieve plates.

[0038] After the separation and screening work is completed, the staff can open the sealed door 11 and then sort and remove the defective drugs on each screening plate, thus completing the multi-stage separation and screening of defective drugs.

[0039] In summary, compared with traditional manual sorting and sieving, this utility model can automatically complete the automatic sieving process of defective tablets, effectively improving the automated separation effect of defective tablets. It can automatically separate and sieve defective drugs according to their size, making it more usable. By replacing manual labor with machines to perform defective drug separation operations, it can effectively improve the separation efficiency of defective tablets, increase the production and recycling speed of drugs, reduce the labor intensity of workers, and effectively reduce human resource costs, thereby improving the economic benefits of enterprises.

[0040] Furthermore, the internal mixing structure effectively drives the movement of defective tablets on each screening plate, effectively preventing defective medicines from accumulating statically on the screening plates, improving the material feeding and separation effect, and avoiding blockage caused by the accumulation of defective medicines. It has a good practical effect in promoting screening. At the same time, it can be used in conjunction with the vibration motor 11, which drives each screening plate to vibrate. In actual use, it has a good vibration screening and feeding effect, which can effectively improve the feeding and separation speed of the separation device of this utility model. It has the practical characteristics of vibration separation and is more practical.

Therefore, the embodiments should be considered illustrative 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
