The upper chute is connected to the lower chute. The part of the upper chute, which covers the upper part of the area of the lower chute provided with the small-particle-size defective capsule through holes, is provided with capsule scattering holes 21. The diameter of the capsule scattering hole is 2-2.5 times of the diameter of the capsule, namely two capsules can vertically pass through at one time. The right end of the upper chute, i.e. the bottom end, is provided with a stop plate 22. A capsule transition cavity 4 is formed between the upper chute and the lower chute. The capsule transition chamber is provided with a capsule outflow opening 41. The height dimension of the capsule outlet along the vertical direction is 1.5-2 times of the diameter of the capsule.

The lower chute shaking mechanism is a vibrating motor. The lower chute and the upper chute vibrate under the action of the lower chute shaking mechanism.

The capsule shell cutting mechanism comprises a discharging hopper 81, a vertical rotating shaft 82 which is rotatably connected to the rack and a rotating shaft driving mechanism 88 which drives the vertical rotating shaft to rotate. The vertical rotating shaft is provided with a feeding ring 83, an upper supporting ring 84, a discharging ring 85 and a lower supporting ring 86 from top to bottom in sequence. The feeding ring is fixedly connected with the rotating shaft and can rotate along with the vertical rotating shaft. The feeding ring is provided with a plurality of upper capsule storage through holes 831 which are distributed along the circumferential direction of the feeding ring and extend axially. The lower hopper 81 includes a first collecting hopper 811 for collecting capsules dropped from defective capsules of small particle size through holes, a second collecting hopper 812 for collecting capsules dropped from the lower end of the lower chute, and a lower nozzle 813 capable of aligning with the upper capsule storage through hole.

The blanking ring is fixedly connected with the vertical rotating shaft and can rotate along with the vertical rotating shaft. The blanking ring is provided with a plurality of lower capsule storage through holes 851 which extend along the circumferential direction of the blanking ring in the axial direction. The lower capsule storage through holes 851 are aligned in one-to-one correspondence with the upper capsule storage through holes. The upper supporting ring and the machine frame are sleeved on the vertical rotating shaft. The upper supporting ring is provided with an upper supporting ring part capsule falling notch 841. The upper supporting ring blocks the upper end of the lower capsule storage through hole aligned with the upper supporting ring to support the capsule in the upper capsule storage through hole aligned with the upper supporting ring. The upper supporting ring is in sealing and abutting connection with the upper end of the blanking ring. The upper supporting ring covers the upper end of the lower capsule storage through hole aligned with the upper supporting ring. The lower supporting ring is provided with a lower supporting ring part capsule falling notch 861. A vibrating screen is arranged below the falling notch 861 of the lower supporting ring part capsule. The lower supporting ring is in sealing and abutting connection with the lower end of the blanking ring. The lower supporting ring seals and blocks the lower end of the lower capsule storage through hole aligned with the lower supporting ring. The upper end and the lower end of the lower capsule storage through hole are respectively sealed by the upper supporting ring and the lower supporting ring, and the lower capsule storage through hole forms a sealed cavity. An arc-shaped slot 862 is arranged on the part of the upper end surface of the lower supporting ring, which is positioned between the falling gap of the capsule of the upper supporting ring part and the gap of the capsule of the lower supporting ring part. The arc slot 862 allows communication between the lower capsule storage through hole located between the upper ring portion capsule drop gap and the lower ring portion capsule gap. The lower capsule storage through hole is disconnected with the atmosphere when being communicated with the arc-shaped groove. The arc-shaped groove is provided with an air exhaust hole 863. The suction hole is connected with the air inlet of the vacuum pump 87. An air cavity 865 which is correspondingly communicated with the lower capsule storage through holes one by one through a communication hole 864 is arranged in the blanking ring. A knife handle 866 is connected in the communicating hole in a sealing and sliding way. The knife handle is connected with a knife strip 867 with a cutting edge facing the lower capsule storage through hole and used for cutting the capsule in the lower capsule storage through hole into two halves. When the lower capsule storage through hole is communicated with the atmosphere, the air pressure in the air cavity is equal to the air pressure in the lower capsule storage through hole. The knife handle is provided with a vertical through hole 8661 which can be positioned in the discharging ring when the knife strip cuts the capsule and a horizontal through hole 8662 which is crossed with the vertical through hole. The lower capsule storage through hole is provided with a knife slot 868 aligned with the communicating hole and allowing the knife strip to pass through. An air inlet gap 869 is arranged between the two ends of the knife strip and the knife groove.

The radial end of the upper supporting ring is fixed with the rack through a first connecting rib 842, the other end of the upper supporting ring is connected with the radial end of the lower supporting ring through a second connecting rib 843, and the radial other end of the lower supporting ring is connected with the rack through a third connecting rib 844. The connecting mode can effectively prevent the upper supporting ring and the lower supporting ring from being bent at the connecting part of the rack to cause the sealing and abutting connection of the upper supporting ring and the lower supporting ring with the blanking ring, and the service life of the connecting mode is prolonged.

The shaft driving mechanism 88 includes a driven gear 881 provided on the vertical shaft, a driving gear 882 meshing with the driven gear, and a driving motor 883 driving the driving gear to rotate. The driving motor is connected with the frame.

When the capsule collecting device is used, capsules are poured into the upper sliding groove from the upper end of the upper sliding groove, the upper sliding groove and the lower sliding groove swing in the front-back and left-right directions under the action of the lower sliding groove shaking mechanism, the capsules at the upper end slide downwards in a matching mode with gravity, the capsules fall through the capsule scattering holes through the upper sliding groove and scatter into the capsule transition cavity 4 in a relatively dispersed mode, and the capsules with the diameter smaller than the requirement fall out of the small-particle-size defective capsule through holes 12 in the process of moving towards the right in the capsule transition cavity and enter the first collecting hopper 811. The rest capsules enter the bottom end of the lower chute in a single-layer mode, the good capsules fall off when passing through the good capsule particle diameter through holes 11, and finally the capsules with the diameter larger than the requirement fall off from the lower end of the lower chute and fall into the second collecting hopper 812. The rotating shaft driving mechanism 88 drives the vertical rotating shaft to rotate, the vertical rotating shaft drives the feeding ring and the discharging ring to synchronously rotate, and when the feeding ring rotates to the upper capsule storage through hole and the discharging nozzle 813, the capsule in the discharging hopper falls into the upper capsule storage through hole. When the feeding ring rotates to align the upper capsule storage through hole with the upper supporting ring capsule falling gap and the lower supporting ring capsule gap, the upper supporting ring loses the supporting effect on the capsule, the capsule drops into the lower capsule storage through hole from the upper capsule storage through hole, the lower capsule storage through hole is sealed by the upper supporting ring and the lower supporting ring at two ends when the feeding ring rotates to the lower capsule storage through hole, and the lower capsule storage through hole is aligned with the arc-shaped groove 862, vacuum is formed in the capsule storage through hole under the vacuumizing free running of the vacuum pump, so that the cutter handle is driven in gas in the air cavity 865 to enable the cutter bar to move towards the lower capsule storage through hole, and therefore the capsule located in the lower capsule storage through hole is cut into two halves. When the lower feeding ring rotates to align the lower capsule storage through hole with the capsule falling notch of the lower supporting ring part, the lower capsule storage through hole is vacuumized, so that the cutter bar is reset again, the cut capsule falls onto the vibrating screen from the capsule falling notch of the lower supporting ring part, and the vibrating screen separates the medicine grains in the capsule from the capsule shell under the screen.
