Description

Technical Field

[0001] The invention relates to the technical field of drug particle size analysis and detection, and in particular to a drug particle size analysis and detection device. Background Art

[0002] The drug particle size analysis and detection device is mainly used to measure the size, distribution and other physical properties of drug particles. It is an indispensable and important tool in the drug research and development and production process. The drug particle size analysis and detection device mainly includes laser particle size analyzers, microparticle laser particle size analyzers and other types. They use different principles and technical means to achieve accurate measurement of drug particle size.

[0003] Chinese patent publication number CN117092000A discloses a drug particle size analysis and detection device and method, including a shell and multiple drug classification mechanisms, the drug classification mechanisms include a driving component, a cam, a screen installation frame, a drug screening net and multiple reset springs, the shell provides installation conditions for the multiple drug classification mechanisms, and the drugs can be classified through the multiple drug classification mechanisms. The drug screening nets on each drug classification mechanism have different apertures, and the apertures decrease from top to bottom. When the drugs need to be screened, the raw materials are poured into the feed port on the shell, the driving component is started, and the driving component drives the cam to rotate. The cam pushes the screen installation frame to slide in the shell, and the rebound force of the multiple reset springs pushes the screen installation frame to abut against the cam, thereby realizing the screening of the raw materials in the drug screening net, thereby solving the problem of low efficiency of existing drug classification.

[0004] The above scheme still has the following shortcomings when used in practice: in the drug particle size analysis and testing process, in order to ensure the accuracy and reliability of the particle size analysis results, the staff must first mix the drug powder or granules with the water solvent, and this mixing process needs to achieve a high degree of uniformity. However, the above drug particle size analysis and testing method relies on manual operation, which not only increases the workload, but also introduces the risk of errors caused by human factors. The staff needs to strictly control the ratio of the drug and the solvent during the mixing process. Any slight deviation may affect the final analysis results. In addition, manual mixing is difficult to ensure the consistency and repeatability of each operation, which restricts the efficiency of the entire testing process. Summary of the invention

[0086] like Figure 7 , Figure 8As shown, the mixing assembly includes: a support frame 101, fixedly mounted on the inner wall of the pretreatment box 2; a mixing bucket 102, threadedly mounted on the inner wall of the support frame 101, and a liquid adding pipe 12 is provided through the bottom surface of the liquid storage tank 6, and the end of the liquid adding pipe 12 away from the liquid storage tank 6 is located directly above the mixing bucket 102; a fixed gear ring 103, fixedly sleeved on the outer wall of the mixing bucket 102; an adjusting gear 104, rotatably mounted at a corner of the top surface of the support frame 101; a servo motor 105, fixedly mounted at a corner of the bottom surface of the support frame 101, and the output end of the servo motor 105 is fixedly connected to the adjusting gear 104; the mixing assembly also includes: a sealing ring 106, fixedly mounted on the inner wall of the discharge end of the mixing bucket 102; a fixed rod 107, fixedly mounted on the inner wall of the sealing ring 106; a sliding rod 108, which is provided through the fixed rod 1 07 is away from the end connected to the sealing ring 106; the sealing plug 109 is fixedly installed on the top of the sliding rod 108; the spring 1010 is mounted on the sliding rod 108 and is located below the fixed rod 107, and the two ends of the spring 1010 are fixedly connected to the sliding rod 108 and the fixed rod 107 respectively; the bottom plate 1011 is fixedly installed at the bottom end of the sliding rod 108; when the medicine is added to the mixing bucket 102, the liquid adding tube 12 can be opened to add the water solvent in the liquid storage tank 6 to the mixing bucket 102 for preliminary mixing with the medicine.

Since the mixing tank 114 is inclined and the connecting rod 113 is arranged at the side position of the top of the transmission column 111, the transmission column 111 can drive the mixing tank 114 to rotate when it rotates, so as to achieve the oscillation of the mixing tank 114, so that the medicine can be fully mixed. After the mixing is completed, the feed pipe on the laser particle size analyzer 1 can be connected to the discharge pipe 115 on the mixing tank 114, so that the mixture in the mixing tank 114 is added to the laser particle size analyzer 1, and then the particle size analysis of the medicine can be completed by the laser particle size analyzer 1.

[0088] The specific working principle of the present invention is as follows:

[0089] First, the drug to be tested can be added to the storage box 4, and the drug can enter the hopper 5 under the action of gravity. Then, the position of the adjustment plate 73 can be adjusted according to the amount of drug to be tested. When adjusting, the knob 85 can be rotated to drive the transmission gear 84 to rotate through the transmission rod 83. The transmission gear 84 is engaged with the tooth groove 87, so that the lifting plate 82 can be driven to slide along the fixed frame 81, thereby driving the connecting sleeve 79 and the adjustment plate 73 to slide along the support rod 71 through the connecting frame 86, so that the overlapping part of the adjustment sleeve 76 and the guide sleeve 75 changes, thereby realizing the adjustment of the amount of drug loaded in the guide sleeve 75 and the adjustment sleeve 76;

[0090] After the adjustment is completed, the driving motor 93 can be turned on to drive the semicircular plate 94 and the driving half gear 95 to rotate. When the semicircular plate 94 rotates, it can rotate inside the arc groove on the mounting plate 92, so that the support rod 71 can load and unload materials stably, and when the semicircular plate 94 is separated from the mounting plate 92, the driving half gear 95 can mesh with the follower gear 91 to drive the follower gear 91 to rotate. When the semicircular plate 94, the mounting plate 92, the follower gear 91 and the driving half gear 95 are used in conjunction with each other, the lower support rod 71 can rotate 180°. In the initial state, the opening 74 is located at a position corresponding to the feeding hopper 5. The figure shows the components The position is not shown, the medicine in the storage box 4 can enter the guide sleeve 75 and the adjusting sleeve 76 through the feeding hopper 5, and as the connecting plate 72 and the adjusting plate 73 rotate 180 degrees, the guide sleeve 75 and the adjusting sleeve 76 filled with the medicine can be rotated to the top of the mixing bucket 102, and the support block 78 can be rotated along the bottom surface of the guide ring 710, at this time, the support block 78 can be located at the inclined surface 711 on the guide ring 710, and under the action of the inclined surface 711, the torsion spring can drive the cover plate 77 to rotate to leak the bottom end of the adjusting sleeve 76, and the medicine inside can fall into the mixing bucket 102;

[0091] When the medicine is added to the mixing bucket 102, the liquid adding pipe 12 can be opened so that the water solvent in the liquid storage tank 6 is added to the mixing bucket 102 for preliminary mixing with the medicine. After mixing, the servo motor 105 can be turned on to drive the adjusting gear 104 to rotate. The adjusting gear 104 is meshed with the fixed gear ring 103, so that the mixing bucket 102 can be driven to rotate. The mixing bucket 102 is threadedly connected to the support frame 101, so it can move in the vertical direction during rotation, so that the discharge end of the mixing bucket 102 enters the feeding end of the mixing tank 114. The top rod 116 inside the feeding end of the mixing tank 114 can lift the bottom plate 1011, the sliding rod 108 and the sealing plug 109. After the sealing plug 109 is separated from the sealing ring 106, the mixture in the mixing bucket 102 can be added to the mixing tank 114. After the filling is completed, the servo motor 105 can be reversed to reset the mixing bucket 102 so that it can be used again.

[0092] After the mixture is added to the mixing tank 114, the oscillation motor 112 can be turned on to drive the transmission column 111 to rotate. Since the mixing tank 114 is tilted and the connecting rod 113 is arranged at the side position of the top of the transmission column 111, the transmission column 111 can drive the mixing tank 114 to rotate when it rotates, so as to achieve the oscillation of the mixing tank 114, so that the medicine can be fully mixed. After the mixing is completed, the feed pipe on the laser particle size analyzer 1 can be connected with the discharge pipe 115 on the mixing tank 114, so that the mixture in the mixing tank 114 is added to the laser particle size analyzer 1, and then the particle size analysis of the medicine can be completed by the laser particle size analyzer 1.
