A support frame 11 is installed in the middle of the installation frame 1. Four visual recognition devices 12 are installed on the support frame 11. A connection block 13 is installed on the left side of the partition plate 10. An electric slide rail 14 is installed on the connection block 13. The visual recognition device 12 is signal-connected to the electric slide rail 14. An electric slider 15 is slidably arranged on the electric slide rail 14. The bottom of the electric slider 15 is fixedly connected with a push plate 16. The push plate 16 slides on the conveyor belt 9. Two guide frames 4 are fixedly connected to the rear side of the upper part of the installation frame 1. A rotating shaft I 5 is rotatably arranged by the two guide frames 4 together. A driving motor 6 is installed on the installation frame 1. The output shaft of the driving motor 6 is connected to the rotating shaft I 5. Two support cylinders 7 are fixedly connected to the left and right sides of the installation frame 1. A rotating shaft II 8 is rotatably arranged between the two support cylinders 7. Four conveyor belts 9 are jointly sleeved on the rotating shaft I 5 and the rotating shaft II 8. Eight partition plates 10 are fixedly connected to the rotating shaft I 5 and the rotating shaft II 8 together. A blanking port is arranged on the left partition plate 10. The partition plate 10 is in contact with the conveyor belt 9. A transparent glass II 39 is embedded on the right side of the material feeding frame 2. Through the transparent glass II 39, it is convenient to check the storage capacity of the capsules inside the material feeding frame 2. The two support cylinders 7 are jointly fixedly connected with a guide frame 20. The guide frame 20 guides the qualified capsules to prevent the qualified capsules from falling outside the finished product placement frame 19.

[0027] When the device needs to be used, start the driving motor 6. The output shaft of the driving motor 6 rotates to drive the rotating shaft I 5 to rotate, thereby driving the conveyor belt 9 to rotate. Then pour the capsules into the material feeding frame 2. Then, start the visual recognition device 12. The capsules fall on the conveyor belt 9. The visual recognition device 12 recognizes the capsules. When a damaged capsule is recognized, the visual recognition device 12 sends a signal to start the electric slide rail 14, so that the electric slider 15 drives the push plate 16 to move leftward, and then pushes the damaged capsule into the defective product placement frame 18, thereby quickly screening out the damaged capsules and improving the detection efficiency. After screening out the damaged capsules, the electric slider 15 drives the push plate 16 to move rightward to reset, and continues to convey the qualified capsules forward and fall into the finished product collection frame.

[0028] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 4 and Figure 5Two support seats 22 are installed on the mounting frame 1, and a screen rod 23 is rotatably arranged on the two support seats 22. A limiting cylinder 21 is arranged on the screen rod 23, and the limiting cylinder 21 is connected to the lower hopper 3. A plurality of discharge troughs 24 are opened on the screen rod 23. The screen rod 23 and the rotating shaft Ⅰ5 are jointly sleeved with two transmission components 25, and a transparent glass Ⅰ26 is embedded on the limiting cylinder 21.

[0029] After the capsule is poured into the discharge frame 2, it passes through the limiting cylinder 21 and is guided into the interior of the sieve rod 23. At this time, the output shaft of the driving motor 6 rotates to drive the transmission assembly 25 to rotate accordingly, and the transmission assembly 25 drives the sieve rod 23 to rotate. In this process, the capsule is guided in an orderly manner inside the sieve rod 23, and is accurately discharged onto the conveyor belt 9 through the discharge port at the lower end of the limiting cylinder 21, thereby realizing fine control of the discharge amount, which not only ensures the continuity and stability of the processing process, but also significantly improves the efficiency and accuracy of subsequent detection work.

[0030] See also Figure 4 , Figure 5 and Figure 6 The discharge frame 2 is provided with a sliding frame 27 in a sliding manner, and a limit shaft 28 is rotatably provided inside the sliding frame 27. A flap 29 is fixedly connected to the limit shaft 28. Torsion springs 30 are sleeved at both ends of the limit shaft 28. The two ends of the torsion spring 30 are respectively connected to the sliding frame 27 and the flap 29. Magnetic blocks I 31 are installed on the left and right sides of the sliding frame 27. Four guide rods 32 are fixedly connected to the outside of the discharge frame 2. A sliding frame 33 is slidably provided with the four guide rods 32. Magnetic blocks II 34 are installed on the left and right sides of the sliding frame 33. The front side of the discharge frame 2 is provided with a press Button 37, the sliding frame 33 can contact the button 37, an alarm 38 is installed on the lower front side of the discharge frame 2, the button 37 is located above the alarm 38, the alarm 38 is electrically connected to the button 37, and the left and right sides of the sliding frame 27 are fixedly connected with pull rods 35, the pull rods 35 increase the fulcrum between the hand and the sliding frame 27, and then it is convenient to pull the sliding frame 27 upward, and protective covers 36 are arranged on the left and right sides of the sliding frame 27, and the torsion spring 30 is located inside the protective cover 36, so as to protect the torsion spring 30 and prevent foreign matter from being entangled on the torsion spring 30.

[0031] Initially, the pull rod 35 is moved upward to make the sliding frame 27 located at the inner top edge of the feeding frame 2. At this time, under the action of the magnet Ⅰ 31 and the magnet Ⅱ 34, the sliding frame 27 drives the sliding rack 33 to move to the outer top edge of the feeding frame 2. When the capsule is added, the extrusion flap 29 rotates downward, and the torsion spring 30 undergoes elastic deformation. After the capsule falls into the interior of the feeding frame 2, the torsion spring 30 returns to its original shape, causing the flap 29 to rotate upward to its original position, closing the top of the feeding frame 2. At this time, the capsule at the top in the feeding frame 2 abuts against the sliding frame 27. As the number of capsules in the feeding frame 2 gradually decreases, due to the influence of gravity, the sliding frame 27 moves downward. Under the action of the magnet Ⅰ 31 and the magnet Ⅱ 34, the sliding frame 27 drives the sliding rack 33 to smoothly slide down along the preset guide rod 32. When there is a small amount of capsules in the feeding frame 2, the continuous downward movement of the sliding rack 33 will touch the button 37, thereby activating the alarm 38, and the alarm 38 sounds, reminding the staff to replenish the capsules in the feeding frame in a timely manner to ensure the continuity and efficiency of the production or detection process.
