[0027] Among them, it also includes a feeding mechanism, which cooperates with the drug hardness detection mechanism. The feeding mechanism includes a plurality of rectangular drug discharge ports 24 and a drug body discharge port 26 on the side away from the rotating shaft 5. Each rectangular drug discharge port 24 is provided with a rectangular groove 36 on the side away from the corresponding drug body discharge port 26.

The other end of the second release tube 27 extends to the top of the bottom plate 1 and cooperates with one of the connecting ports 25. Furthermore, a sealing ring is installed at this end of the second release tube 27 to ensure the actual connection sealing.

[0028] In the present invention, when in use, a tablet is placed in the rectangular medicine discharge port 24 at the left front. When testing, the drive motor 6 is started to rotate one-third of a circle, and the transmission of the first gear 7 and the second gear 8 allows the shaft 5 to rotate one-third of a circle, and the rectangular medicine discharge port 24 at the left front rotates to the rightmost side. At this time, the first near-infrared detection head 28 and the second near-infrared detection head 29 can synchronously detect the two sides of the tablet to complete the detection operation, and the cooperation of the first light shielding box 17 and the second light shielding box 18 can prevent external light from interfering with the detection; During the rotation of the rotating shaft 5, the transmission of the gearbox 9 will cause the rotating plate 10 to rotate for multiple circles. The rotation of the rotating plate 10 will cause the first piston block 19 to reciprocate left and right through the connecting rod 11. The left and right reciprocating motion of the first piston block 19 will generate a one-way gas flow between the outside, the first piston cylinder 12 and the gas temporary storage cylinder 13 through the cooperation of the one-way port 20 and the one-way tube 15. The one-way gas flow can continuously gather gas at the bottom of the gas temporary storage cylinder 13. Since the electromagnetic valve in the first release tube 14 is powered on and closed, the first release tube 14 is in a closed state at this time. The gathering of gas will drive the second piston block 23 to move upward and compress the first spring 22. When the driving motor 6 is powered off, that is, when the medicine rotates to the rectangular medicine discharge port 24 on the far right for detection, the solenoid valve is powered off and turned on. Under the elastic action of the first spring 22, the second piston block 23 moves down quickly, and the gas in the bottom space of the gas temporary storage cylinder 13 is quickly pressed out. The pressed gas will first enter the top space of the second piston cylinder 43. Since the exhaust pores 32 cannot meet the demand for large-scale exhaust, the high-pressure gas gathers in the top space of the second piston cylinder 43, which will push the third piston block 33 to move down and stretch the second spring 31. When the third piston block 33 moves down to a position lower than the second release tube 27, part of the high-pressure gas will be discharged from the second release tube 27. The second release tube 27 cannot meet the demand for rapid discharge of a large amount of gas, resulting in the top of the second piston cylinder 43 still being in a high-pressure gas state, pushing the third piston block 33 to continue to move down, and finally using the first connecting column 34 and the annular medicine pressing strip 35, it moves down to hit the medicine. In this way, the hardness detection of the medicine can be realized, and the thickness detection and hardness detection are integrated into one, thereby improving the efficiency of the overall detection. After completing this part of the inspection, with the next start of the driving motor 6, the uninspected medicines released from the left side will rotate again to the right rectangular medicine release port 24, and the inspected medicines in the right rectangular medicine release port 24 will rotate to the left rear. When the driving motor 6 is powered off, the released high-pressure gas will be discharged from the second release tube 27 and will enter the columnar groove at the left rear through the corresponding connecting port 25, pushing the corresponding fourth piston block 37 to move away from the rotating shaft 5. The second connecting column 39 is used to drive the moving bar 40, the fourth spring 42, the sliding bar 16 and the scraper plate 21 to move. The movement of the scraper 21 will push the inspected medicines to move and at the same time scrape the surface of the glass placement plate 30 to prevent tablet fragments from adhering to the glass and affecting the next inspection. Now, in this process, due to the large friction force, the fourth spring 42 will be compressed to a large extent. When the fourth piston block 37 finally moves to the corresponding rectangular groove 36, the high-pressure gas in the columnar groove will be continuously released, and the second piston block 37 will maintain this position. At this time, the moving bar 40 will move to the position that penetrates the medicine discharge port 26 (and no longer moves at this position), and the tablets are pushed out. Just place a collection box here to collect the tested medicines. The high-pressure gas passes through the columnar groove and the rectangular groove 36, and finally moves upward along the rectangular medicine discharge port 24. The emergence of this continuous airflow can avoid the situation that some severely damaged medicine powders diffuse into the environment and finally fall on the nearest glass placement plate 30 when pushing the medicine; It should also be noted that, during the period of time when the moving bar 40 moves to the outside and remains stationary, under the action of inertia and the elastic action of the fourth spring 42, the sliding bar 16 and the scraper plate 21 will shake for many times and finally stop moving. The shaking of the scraper plate 21 can shake off the drugs that are tightly adhered thereto, so as to prevent them from falling on the glass placement plate 30 when moving back and affecting the next detection. When the high-pressure gas is not sufficient to support the third piston block 33 to move downward, the remaining high-pressure gas will be released from the exhaust hole 32 (a small part will be released from the second release tube 27), and the third piston block 33 will move upward (eventually move upward to its original state). When it moves upward to be higher than the second release tube 27, the third spring 38 contracts and pulls the fourth piston block 37, the second connecting column 39, the moving bar 40, the fourth spring 42, the sliding bar 16 and the scraper plate 21 and other structures back to the initial position to facilitate the next drug release process.

The first gear 7 and the second gear 8 drive the rotating shaft 5 to rotate for one third of a circle. The rectangular medicine dispensing opening 24 on the left front rotates to the rightmost side. At this time, a tablet is placed in the rectangular medicine dispensing opening 24 on the left front. Step 3: Start the first near infrared detection head 28 and the second near infrared detection head 29 to detect the coating thickness of the tablets, and at the same time, after the driving motor 6 is powered off, automatically perform hardness detection; Step 4: Start the drive motor 6 and rotate it one-third of a circle.

Continue this process to achieve continuous drug testing.
