Description

Technical Field

[0001] The present invention relates to the technical field of spectral sampling, in particular to a spectral sampling device for tablet medicines. Background Art

[0002] Spectroscopic analysis refers to a class of analytical methods for substances, primarily including atomic emission spectroscopy, atomic absorption spectroscopy, ultraviolet-visible absorption spectroscopy, and infrared spectroscopy. Spectroscopic analysis can be further categorized into molecular spectroscopy and atomic spectroscopy based on the nature of electromagnetic radiation. It primarily utilizes the transitions of valence electrons within molecules, and therefore the absorption spectrum is determined by the distribution and bonding of valence electrons within the molecule. Spectroscopic analysis offers advantages such as rapid analysis, ease of operation, the absence of pure samples, the ability to simultaneously measure multiple elements or compounds, excellent selectivity, high sensitivity, and minimal sample damage. Existing spectroscopic analyzers can be used for sampling in new material testing, metrology, related standardization, and certification and accreditation services.

[0003] The purpose of drug testing is to prevent substandard drugs from entering the market and ensure drug safety. In the current field of drug testing, spectroscopic sampling is often required for small tablets and pills. In existing technologies, tablet sampling requires first grinding the tablet to obtain a fixed amount of powder, dissolving it, and then placing it in a cuvette. A spectroscopic analyzer is then used to compare the solution with a standard working solution. This process requires grinding, mixing, and aspiration, and involves a lot of manual intervention, resulting in low sampling efficiency and a high risk of errors. Summary of the Invention

[0026] In this embodiment, an arc block 37 is fixed on the top of the rotating rod 35, and the driving shaft 23 is located on the top of the arc block 37 on both sides of the suction component 5 and the driving component 4, and a card frame 48 is slidably connected. The upper end of the card frame 48 is installed with a transmission belt 410, and the upper end of the card frame 48 on one side of the vertical frame 41 is fixed with a shaft 47, and the position of the top of the vertical frame 41 corresponding to the shaft 47 is fixed with a second motor 46, and the output end of the second motor 46 is fixedly connected to the shaft 47. The card connection between the arc block 37 and the card frame 48 is the same as the rotation trajectory of the driving shaft 23, so when the rotating rod 35 of each group of grinding and mixing components 3 rotates to the card frame 48 position, the arc block 37 can automatically engage with the card frame 48, wherein the card frame 48 at the top of the suction component 5 is fixed by the mounting bracket. The card frame 48 on the front of the vertical frame 41 is installed on the side plate of the vertical frame 41 through the shaft 47. Under the drive of the transmission belt 410 and the second motor 46, the two sets of card frames 48, the arc block 37 and the rotating rod 35 can be driven to rotate at the same time. At this time, the grinding plate 33 and the mixing barrel 34 of the grinding and mixing assembly 3 facing the vertical frame 41 are both close to the grinding table 31. In this process, the tablets in the grinding table 31 are ground by the grinding plate 33 and the components fall into the mixing barrel 34 to prevent powder from falling. The grinding and mixing assembly 3, the grinding plate 33 and the mixing barrel 34 on the top of the suction assembly 5 are away from the grinding table 31.

The slide 13 is fixed, and moves to the position at the bottom of the straight tube 55 along the slide rail 11 through the screw rod 15. When the driving component 4 drives the upper pressure plate 411 to squeeze the grinding plate 33 and cover the grinding table 31, the connecting frame 44 descends synchronously, and the grinding and mixing components 3 of the opposite group are sent into the cleaning tank 21 for cleaning. At the same time, through the connection of the fixed frame 51, the suction pump 52 descends, and the straight tube 55 is inserted into the jack of the cuvette 12. The electric push rod 53 drives the inclined bellows 54 to expand and insert it into the mixing barrel 34 away from the grinding table 31, and sends the stirred and mixed solution into the cuvette 12. Then, the screw rod 15 drives the slide 13 and the cuvette 12 into the detection chamber 14 for detection. The detection content of this part is the same as the existing spectral detection technology. After the detection is completed, the screw rod 15 sends the cuvette 12 out from the other end of the slide rail 11.

[0028] When using the device, the tablet to be tested is placed inside the opened grinding table 31, and then the first motor 22 drives the drive shaft 23 to rotate, and the grinding and mixing assembly 3 rotates to the front of the vertical frame 41, and the grinding plate 33 and the mixing barrel 34 are merged with the grinding table 31 through the upper pressing plate 411 and the lower pressing plate 413.

At the front end of the vertical frame 41, the rotation of the bidirectional screw 42 is driven by the motor, and the two screw blocks 43 drive the upper pressing plate 411 and the lower pressing plate 413 to squeeze the grinding plate 33 and the mixing barrel 34, so that they are close to the grinding table 31 and merged into a whole.

Then the driving shaft 23 continues to rotate and opens on one side of the suction component 5. The engagement of the arc block 37 with the card frame 48 is the same as the rotation trajectory of the driving shaft 23. Therefore, when the rotating rod 35 of each group of grinding and mixing components 3 rotates to the card frame 48 position, the arc block 37 can automatically engage with the card frame 48. The card frame 48 at the top of the suction component 5 is installed on the side plate of the vertical frame 41 through the mounting bracket, and the card frame 48 on the front of the vertical frame 41 is installed through the shaft 47.

At this time, the grinding plate 33 and the mixing barrel 34 of the combined component 3 are both close to the grinding table 31. In this process, the tablets in the grinding table 31 are ground by the grinding plate 33 and the components fall into the mixing barrel 34 to prevent powder from falling. The grinding and mixing component 3, the grinding plate 33 and the mixing barrel 34 on the top of the suction component 5 are away from the grinding table 31. At this time, the rotation of the rotating rod 35 can drive the rotation of the stirring frame, which is convenient for adding the mixed liquid and accelerating the mixing of the mixed liquid and the tablet powder. The upper pressing plate 411 and the lower pressing plate 413 are driven to move by the driving component 4, so that the grinding and mixing components 3 can be combined into a whole, which is convenient for receiving the ground powder. At the same time, through the connection of the connecting frame 44, the push plate 45 located at the top of the cleaning tank 21 squeezes the connecting plate 25 and slides downward along the slide groove 26. , insert the grinding and mixing component 3 into the cleaning tank 21, rinse or soak the grinding and mixing component 3 with a specific cleaning liquid to facilitate recycling, and send it into the cuvette 12 through the suction component 5. The cuvette 12 is placed on the top of the slide 13 manually, and then the clamping plate 16 is used to clamp and fix the bottom edge of the cuvette 12. The slide 13 moves along the slide rail 11 to the bottom of the straight tube 55 through the screw rod 15. When the driving component 4 drives the upper pressure plate 411 to squeeze the grinding plate 33 and cover the grinding table 31, the connecting frame 44 is synchronously lowered to send the opposite group of grinding and mixing components 3 into the cleaning tank 21 for cleaning. At the same time, through the connection of the fixing frame 51, the suction pump 52 is lowered, and the straight tube 55 is inserted into the socket of the cuvette 12.The electric push rod 53 drives the inclined bellows 54 to expand and insert into the mixing barrel 34 away from the grinding table 31, sending the stirred and mixed solution into the cuvette 12. The screw 15 then drives the slide 13 and the cuvette 12 into the detection chamber 14 for detection. After use, the grinding and mixing assembly 3 rotates to the top of the cleaning tank 21 and is driven by the drive assembly 4 to be inserted into the cleaning tank 21 for cleaning. Four sets of grinding and mixing assemblies 3 can be reused to perform multiple spectral sampling.
