Technical Field

[0001] The invention relates to the field of sampling and testing, specifically a sampling and testing device for the production of chemical preparations. Background Technology

[0002] Chemical preparations mainly refer to drugs whose active ingredients are chemically synthesized. Corresponding to them are traditional Chinese medicine preparations and biological preparations. Chemical preparations need to be sampled and tested during production in order to understand the specific values ​​of the ingredients in the preparation.

[0003] Existing sampling and testing devices can only perform single-sample testing at a time, resulting in limited data and a lack of control data sets. This can lead to significant analytical errors in data interpretation. Furthermore, after adding the test reagent, the operator often needs to manually shake the sample to ensure rapid and uniform mixing, which is cumbersome and inconvenient. In addition, chemical preparations require testing for multiple data items per sample, and manually shaking each sample individually is labor-intensive and inefficient, impacting the production schedule of chemical preparations. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the present invention provides a sampling and testing device for chemical preparation production, which solves the technical problems of existing equipment being able to only perform sampling and testing of a single sample solution at a time, resulting in relatively simple data information, lack of control data groups, and easy to have large analytical errors in the judgment of data information. In addition, after the addition of the test reagent, the tester often needs to manually shake and vibrate to make the sample solution and the test reagent mix quickly and evenly, which is labor-intensive and has low testing efficiency.

Detailed Implementation

[0028] This invention provides a sampling and testing device for chemical preparation production, which solves the technical problems of existing equipment that can only perform sampling and testing of a single sample solution at a time, resulting in relatively simple data information, lack of control data groups, and easy to make large analytical errors in the judgment of data information. In addition, after the addition of the test reagent, the tester often needs to manually shake and vibrate to make the sample solution and test reagent mix quickly and evenly, which is labor-intensive and has low testing efficiency.

[0029] Reference Appendix Figure 1-7 A sampling and testing device for chemical preparation production includes: a platform 10, a top plate 11 disposed above the platform 10, and two support shafts 12 symmetrically distributed on the top of the platform 10 for supporting and fixing the top plate 11.

[0030] A support plate 20 is provided on each side of the two support shafts 12 that are far apart from each other. The support plate 20 has multiple placement slots 21 that are evenly distributed in a ring along its circumference. Each placement slot 21 has a detection tube 22 inside for holding the sample. The support plate 20 has a limit component 40 inside for blocking and limiting the detection tube 22 so that the detection tube 22 cannot move laterally out of the placement slot 21.

[0031] A bracket 30 is provided on the support shaft 12 to support the support plate 20 and the detection tube 22. The bracket 30 includes an upper support plate 31, a lower support plate 32, and a rotating shaft 33. The upper and lower ends of the rotating shaft 33 rotate inside the upper support plate 31 and the lower support plate 32, respectively, while the support plate 20 is fixed outside the rotating shaft 33. The upper support plate 31 and the lower support plate 32 both rotate outside the support shaft 12, and the lower support plate 32 is located at the bottom of the detection tube 22. The support plate 20 and the detection tube 22 are supported by the rotating shaft 33 and the lower support plate 32. The upper support plate 31 can be pushed to support the support plate 20. The lower support plate 32 rotates along the support shaft 12, causing the support plate 20 and the detection tube 22 to move below the top plate 11. A drive mechanism 50 is provided between the top plate 11 and the rotating shaft 33 to drive the rotating shaft 33 to rotate. A liquid separation assembly 60 is provided on the top of the top plate 11 to separate the materials inside the multiple detection tubes 22. A sampling and conveying mechanism 70 is provided on one side of the liquid separation assembly 60 to extract and convey the sample liquid to the liquid separation assembly 60. A liquid delivery mechanism 80 is provided on the other side of the liquid separation assembly 60 to deliver the detection agent inside the liquid separation assembly 60.

[0032] refer to Figure 5-7The support plate 20 has a mounting groove 23 in the middle. The limiting component 40 is set inside the mounting groove 23. The limiting component 40 includes a support ring 41 that rotates inside the mounting groove 23. Multiple L-shaped stops 42 are evenly distributed around the outside of the support ring 41. The multiple L-shaped stops 42 are respectively set outside the multiple detection tubes 22. By rotating the support ring 41, the L-shaped stops 42 are rotated to the outside of the detection tubes 22, blocking and limiting them so that they cannot leave the inside of the placement groove 21. A first magnet 231 is fixed inside the mounting groove 23. A second magnet 421 that attracts the first magnet 231 is fixed at the end of the L-shaped stops 42. After the L-shaped stops 42 block the detection tubes 22, the first magnet 231 and the second magnet 421 attract each other, fixing the L-shaped stops 42. This prevents the support ring from rotating randomly without external force, improving the limiting effect of the L-shaped stops 42 on the detection tubes 22.

[0033] refer to Figure 4 The drive mechanism 50 includes a motor 51 mounted on the top plate 11. The output end of the motor is equipped with a drive gear 52 located below the top plate 11. A driven gear 53 adapted to the drive gear 52 is mounted on the outside of the rotating shaft 33. After the rotating shaft 33 moves below the top plate 11, the driven gear 53 can mesh with the drive gear 52. The motor 51 drives the drive gear 52 to rotate, which in turn drives the driven gear 53 to rotate the rotating shaft 33. This causes the support plate 20 to drive multiple detection tubes 22 to rotate synchronously, thereby shaking the sample liquid and detection reagent inside the detection tubes 22, so that they can be quickly and evenly mixed.

[0034] refer to Figure 1-3 The liquid separation assembly 60 includes an annular tube 61, with multiple annularly distributed feed tubes 62 inserted into the bottom of the annular tube 61. The bottom ends of the multiple feed tubes 62 are all inserted into the top plate 11, and the distance between two adjacent feed tubes 62 is equal to the distance between two adjacent placement slots 21. After the support plate 20 moves to below the top plate 11, the detection tubes 22 in the multiple placement slots 21 can correspond one-to-one with the multiple feed tubes 62. The annular tube 61 transports the material into the multiple feed tubes 62, and the multiple feed tubes 62 dispense the material into the multiple detection tubes 22.

[0035] refer to Figure 1 and Figure 3The sampling and conveying mechanism 70 includes a sampling pump 71 installed on the top plate 11. The input end of the sampling pump 71 is provided with a sampling hose 72, and the output end of the sampling pump 71 is provided with a sample outlet pipe 73 inserted into the annular pipe 61. The sample outlet pipe 73 is provided with a first solenoid valve 74. The sampling pump 71 draws the sample liquid from inside the production equipment through the sampling hose 72 and discharges it into the annular pipe 61 through the sample outlet pipe 73 for sample liquid dispensing. The first solenoid valve 74 facilitates the sealing of the sample outlet pipe 73 to prevent the material from flowing in the sample outlet pipe 73.

[0036] refer to Figure 1-3 The infusion mechanism 80 includes multiple infusion tubes 81 inserted into the top of the annular tube 61. Each of the multiple infusion tubes 81 is equipped with a second solenoid valve 82. Each infusion tube 81 is equipped with a test reagent storage tank at its top. The test reagent in the test reagent storage tank is delivered to the annular tube 61 by the infusion tube 81, and then dispensed into multiple test tubes 22 for sample liquid testing. The second solenoid valve 82 can seal the inside of the infusion tube 81 to prevent the material from flowing in the infusion tube 81.

[0037] refer to Figure 1-4 The base 10 has a cavity 13 inside, and a tray 14 is provided inside the cavity 13. The tray 14 has multiple slots 141 inside, through which the detection tube 22 can be inserted into the tray 14, thereby storing the detection tube 22 inside the cavity 13. A positioning block 321 is fixed on the lower support plate 32. The positioning block 321 has a slot 322 inside that is adapted to the support shaft 12. After the lower support plate 32 rotates around the support shaft 12 to below the top plate 11, the positioning block 321 can be engaged with the outside of another support shaft 12 through the slot 322, thereby completing the positioning of the lower support plate 32.

[0038] Working principle: Multiple detection tubes 22 are placed inside multiple placement slots 21 on the support plate 20. The support ring 41 is rotated to move the L-shaped stop bar 42 to the outside of the detection tube 22, blocking and limiting it. Then, the upper support plate 31 and the lower support plate 32 are pushed to rotate along the support shaft 12, so that the support plate 20 and the detection tubes 22 move below the top plate 11, so that the driven gear 53 and the driving gear 52 mesh, opening the first solenoid valve 74. The sample liquid is drawn from the inside of the production equipment through the sampling pump 71 and the sampling hose 72, and discharged into the annular pipe 61 through the sample outlet pipe 73. The sample liquid is then distributed into the multiple detection tubes 22 through multiple discharge pipes 62. Then, the first solenoid valve 74 is closed and the second solenoid valve 82 is opened, and the detection reagent in the detection reagent storage tank is delivered through the infusion pipe 81. The sample solution is fed into the annular tube 61, and the feed tube 62 dispenses the sample solution into the interior of multiple detection tubes 22. The motor 51 drives the drive gear 52 to rotate, which in turn drives the driven gear 53 to rotate the shaft 33. This causes the support plate 20 to rotate the multiple detection tubes 22 synchronously, thereby shaking the sample solution and detection reagent inside the detection tubes 22 to achieve rapid and uniform mixing. At the same time, the support plate 20 can be used to place the detection tubes 22 inside another support plate 20. After mixing is completed, the support plate 20 moves the detection tubes 22 with the mixed sample solution away from below the top plate 11. Then, the other support plate 20 is pushed to move the empty detection tubes 22 into the area below the top plate 11, where sample solution is poured in. Another infusion tube 81 is used to introduce other types of detection reagents to test other properties of the sample solution.

[0039] Beneficial effects: It can conveniently and quickly dispense sample solutions into multiple test tubes 22 for each group of tests, and simultaneously shake and mix them, accelerating the mixing rate of sample solution and test reagent, eliminating the trouble of shaking each tube individually for the tester, reducing the tester's labor intensity and improving their work efficiency. Furthermore, by using two support plates 20 alternately, it can conveniently place the test tubes 22 required for different groups of test items, thereby enabling rapid testing of sample solutions for different items, improving sampling and testing efficiency, and enhancing the performance of the equipment.
