Technical Field

[0001] This utility model relates to the field of pharmaceutical tablet processing technology, and more specifically, to a pulverizer for levamlodipine besylate tablets. Background Technology

[0002] Levoamlodipine besylate tablets are a common drug for treating cardiovascular diseases such as hypertension and angina pectoris. In clinical applications, it is sometimes necessary to pulverize the tablets before use, such as for patients with difficulty swallowing, or in certain special drug formulations and experimental scenarios.

[0003] A search revealed that Chinese patent CN221181079U discloses a tablet pulverizing device, which can solve the problems of insufficient tablet pulverization and inconvenient powder handling in existing tablet pulverizing devices.

[0004] However, in actual use, existing pulverizers cause dust to disperse after pulverizing tablets, which can easily affect operators once it is dispersed in the air. In view of this, this utility model proposes a pulverizer for amlodipine besylate tablets. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a benzylsulfonic acid amlodipine tablet pulverizer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a benzylsulfonic acid amlodipine tablet pulverizer, comprising a pulverizing chamber, a sealing cover threaded onto the top of the pulverizing chamber, and a feeding box threaded onto the bottom of the pulverizing chamber. A pulverizing motor is fixedly mounted on the sealing cover, and a rotating shaft is fixedly mounted at the output end of the pulverizing motor. A first pulverizing blade and a second pulverizing blade are respectively provided at the bottom of the rotating shaft, with the second pulverizing blade located at the bottom of the first pulverizing blade.

[0022] As attached Figure 1-5 The illustrated levoamlodipine benzylsulfonic acid tablet pulverizer includes a pulverizing chamber 1. A sealing cover 2 is threaded onto the top of the pulverizing chamber 1, and a feeding box 3 is threaded onto the bottom of the pulverizing chamber 1. A pulverizing motor 4 is fixedly mounted on the sealing cover 2, and a rotating shaft 5 is fixedly mounted on the output end of the pulverizing motor 4. A first pulverizing blade 6 and a second pulverizing blade 7 are respectively arranged at the bottom of the rotating shaft 5, and the second pulverizing blade 7 is located at the bottom of the first pulverizing blade 6. A dust absorption structure is provided on the surface of the sealing cover 2 and on one side of the pulverizing motor 4. The rotating shaft 5, the first pulverizing blade 6 and the second pulverizing blade 7 are all located inside the pulverizing chamber 1, and the first pulverizing blade 6 and the second pulverizing blade 7 are detachably connected to the rotating shaft 5.

[0023] Specifically, in this structure, firstly, the inside of the crushing chamber 1 contains the amlodipine besylate tablets to be crushed. When it is necessary to crush them, the sealing cover 2 is threaded onto the top of the crushing chamber 1, and the rotating shaft 5, the first crushing blade 6 and the second crushing blade 7 are located inside the crushing chamber 1. The loading box 3 is threaded onto the bottom of the crushing chamber 1. At this time, the crushing motor 4 is started, so that the rotating shaft 5, the first crushing blade 6 and the second crushing blade 7 rotate inside the crushing chamber 1 to achieve the purpose of crushing the amlodipine besylate tablets.

[0024] The sealing cover 2 can prevent particles or dust from spilling out during the crushing process. After being filtered, the crushed amlodipine besylate tablets fall into the inside of the feeding box 3. The operator can remove the threads of the feeding box 3 to use the amlodipine besylate tablets inside the feeding box 3. In addition, the sealing cover 2 can also be removed from the crushing chamber 1 by threads, which facilitates the cleaning and maintenance of its interior.

[0025] In a specific embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 3, a dust absorption structure is provided on the surface of the sealing cover 2 and on one side of the crushing motor 4. The dust absorption structure includes a processing box 8, which is located on one side of the crushing chamber 1. Two filter elements 9 are installed inside the processing box 8. A conveying pipe 10 is provided between the processing box 8 and the sealing cover 2. A dust pump 11 is provided on one side of the processing box 8. A connecting pipe 12 and an external discharge pipe 13 are respectively provided at the input and output ends of the dust pump 11. The two ends of the conveying pipe 10 are respectively connected to the processing box 8 and the sealing cover 2. One end of the conveying pipe 10 extends into the interior of the sealing cover 2 and is connected to a filter head 19. One end of the connecting pipe 12 is connected to the processing box 8. Two mounting ports 15 are opened through the surface of the processing box 8. The two filter elements 9 are slidably connected to the processing box 8 through the mounting ports 15. A sealing plate 16 with a sealing strip is fixedly provided at the top of the filter element 9. Threaded holes are opened at the connection between the sealing plate 16 and the processing box 8. Bolts 17 are installed in the internal threads of the threaded holes. A groove 18 is opened on the sealing plate 16.

[0026] Specifically, in this structure, after the levoamlodipine benzyl sulfonate tablets are crushed, a large amount of dust will be inside the crusher, which will subsequently be dispersed into the air and affect the operators. Therefore, after the levoamlodipine benzyl sulfonate tablets are crushed, the dust inside the crusher is transported to the processing box 8 through the conveying pipe 10 by the dust pump 11. The dust is adsorbed by the two filter elements 9 inside the processing box 8. Finally, the filtered air is discharged through the connecting pipe 12 and the external exhaust pipe 13, thereby avoiding the dust from spreading in the air and causing an impact.

[0027] When absorbing the dust inside the pulverizer, one end of the conveying pipe 10 is connected to a filter head 19. The filter head 19 blocks the pulverized medicine to prevent the pulverized medicine from being sucked out along with the dust.

[0028] By removing bolt 17 and moving sealing plate 16 upward through pull groove 18, the operator can pull filter element 9 out of the inside of treatment box 8 through installation port 15, making it easy to disassemble and clean filter element 9. Similarly, filter element 9 can be installed inside treatment box 8 through installation port 15, with sealing plate 16 located inside installation port 15, sealed with sealing strip, and finally tightened with bolt 17 to complete the installation of filter element 9.

[0029] In a specific embodiment, as shown in the appendix Figure 4 As shown, a screen 14 is installed at the bottom of the inner cavity of the crushing chamber 1, and the outer wall of the screen 14 and the inner wall of the crushing chamber 1 are an integral structure.

[0030] Specifically, in this structure, the inside of the grinding chamber 1 is integrally formed with a screen 14. During the grinding process of amlodipine besylate tablets, the qualified drug can be screened through the screen 14 and fall into the inside of the loading box 3, while the incompletely ground drug is located on the surface of the screen 14. Until it is completely ground, all the drug can fall into the inside of the loading box 3 through the screen 14, thus improving the grinding effect.

[0031] Working principle of this utility model:

[0032] This application provides a benzyl amlodipine benzyl sulfonate tablet pulverizer. In specific use, the benzyl amlodipine benzyl sulfonate tablets to be pulverized are first loaded into the pulverizing chamber 1, and the sealing cover 2 is threaded on the top of the pulverizing chamber 1 so that the rotating shaft 5, the first pulverizing blade 6 and the second pulverizing blade 7 are located inside the pulverizing chamber 1. At the same time, the feeding box 3 is threaded on the bottom of the pulverizing chamber 1. At this time, the sealing cover 2 plays the role of preventing the particles or dust from spilling out during the pulverizing process.

[0033] Start the crushing motor 4, which drives the rotating shaft 5 to rotate, thereby causing the first crushing blade 6 and the second crushing blade 7, which are detachably connected to the rotating shaft 5, to rotate inside the crushing chamber 1 to crush the amlodipine benzylsulfonic acid tablets.

[0034] Since the bottom of the inner cavity of the grinding chamber 1 is equipped with a screen 14 that is integral with the inner wall of the grinding chamber 1, during the grinding process, the qualified medicine can be screened by the screen 14 and fall into the inside of the loading box 3, while the incompletely ground medicine remains on the surface of the screen 14. After the grinding is completed, all medicine can fall into the inside of the loading box 3 through the screen 14, thereby improving the grinding effect.

[0035] After the pulverized amlodipine besylate tablets are crushed, the dust pump 11 is started. The dust pump 11 transports the dust inside the pulverizer to the processing box 8 through the conveying pipe 10. The filter head 19 connected to one end of the conveying pipe 10 blocks the pulverized medicine to prevent it from being sucked out along with the dust. The two filter elements 9 inside the processing box 8 adsorb the dust. The filtered air is discharged through the connecting pipe 12 and the external exhaust pipe 13, thereby preventing the dust from spreading in the air and affecting the operators.

[0036] When the filter element 9 needs to be cleaned, the operator removes the bolt 17 and moves the sealing plate 16 upward through the pull groove 18. The filter element 9 is then pulled out from the inside of the treatment box 8 through the installation port 15 for cleaning. After cleaning, the filter element 9 is installed inside the treatment box 8 through the installation port 15, so that the sealing plate 16 is located inside the installation port 15. The sealing strip is used for sealing, and finally the bolt 17 is tightened to complete the installation of the filter element 9.

[0037] The operator can remove the feeding box 3 from the bottom thread of the crushing chamber 1 to use the crushed amlodipine benzylsulfonic acid tablets inside the feeding box 3. In addition, the sealing cover 2 can also be removed and installed from the crushing chamber 1 by thread, which facilitates the cleaning and maintenance of the inside of the crusher.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
