Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1, 2, 3 and 4, a capsule shell cutting mechanism comprises a frame 10, a discharging hopper 81, a vertical rotating shaft 82 rotatably connected to the frame, and a rotating shaft driving mechanism 88 for driving 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 comprises a lower mouth 813 able to be aligned 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 lower 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 upper capsule storage through hole 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 feeding device is used, capsules are poured into the discharging hopper, 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 capsules in the discharging hopper fall 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.
