When the present invention is in use, first adjust the inclination adjustment mechanism 3: turn the rotating handle 301, the rotating handle 301 drives the driving bevel gear 303 to rotate, the driving bevel gear 303 drives the driven bevel gear 304 to rotate, and the driven bevel gear 304 drives the threaded rod 305 to rotate, The threaded rod 305 drives the transmission slider 306 to slide along the T-shaped chute, the transmission slider 306 drives the fourth connecting rod 307 to rotate, and the fourth connecting rod 307 drives the casing 1 to rotate around the hinge point with the bottom plate 2 until the main part of the device is tilted Adjust the degree to the level that the tablet can slide down smoothly and the drive assembly is easy to operate.

Then adjust the dividing mechanism: turn the knob 1005 to drive the first connecting rod 403 to rotate continuously, the first connecting rod 1001 drives the turntable 1002 to rotate, and the turntable 1002 drives the rotating block 1003 to turn to the longitudinal chute 1007; To divide the number of tablets into equal pieces, align the rotating block 1003 with the corresponding horizontal chute 1008, at this time the turntable 1002 drives the first connecting rod 1001 to slide longitudinally, and the first connecting rod 1001 drives the selection block 903 and the corresponding swivel 904 Cooperate; then turn the knob 1005 to drive the rotary block 1003 to rotate into the corresponding horizontal chute 1008 until the rotary block 1003 is embedded in the fixed groove 1009 under the elastic force of the second spring 1010; at this time, the selection block 903 drives the swivel 904 rotates, and the swivel ring 904 drives the rotating connecting rod 905 to rotate, and the rotating connecting rod 905 drives the corresponding stop ring 802 to rotate to the working position; Rotate to the top of one of the first chute 804, so far the setting of the equal parts of the dividing mechanism is completed.

After completing the setting of the dividing mechanism, put the tablet from the drug delivery port 15, the tablet slides along the slideway 11 to the drug blocking mechanism 6 and is blocked by the drug blocking plate 601 and cannot continue to slide down; then run the driving mechanism 4: pull the handle 404 upward , the handle 404 drives the turret 402 to rotate around the hinge point with the sliding rod 401, and the turret 402 drives a pair of first connecting rods 403 to rotate around the hinge point with the bracket 14; The sliding rod 401 slides downward along the bracket 14, the sliding rod 401 drives the first connecting plate 501 to move downward, the first connecting plate 501 drives the second connecting plate 503 to move downward through the third spring 504, and the second connecting plate 503 drives the drive The rod 505 moves downward, and the driving rod 505 drives a pair of trapezoidal sliders 703 to slide toward each other along the trapezoidal chute in the guide block 701; the trapezoidal slider 703 drives the clamping slider 707 to move towards each other through the fourth spring, and the clamping slider 707 Drive a pair of connecting frames 708 to move towards each other, the connecting frame 708 drives the second connecting rod 709 to move, the second connecting rod 709 drives the third connecting rod 711 to rotate around the hinge point with the connecting block 710; the rotation of the third connecting rod 711 drives the clamping The bar slides inwardly along the second guide groove 16, and the four clamping bars move inwardly at the same time to realize the positioning and clamping of the tablet; Sliding inside, the fourth spring is compressed and the force of the clamping rod on the tablet gradually increases, and the tablet is clamped.

After the tablet is clamped, the first connecting plate 501 continues to move downward, the third spring 504 is compressed, and the knife seat 801 affixed to the first connecting plate 501 passes through the opening on the first connecting plate 501 and starts to clamp the tablet. The tablets are divided: the eight blades on the knife seat 801 are all in contact with the tablets, and the blades with the baffle 803 above cannot slide upwards, so the tablets are divided under the support of the baffle ring 802; the blades without the baffle 803 above will Retracts upward under pressure without splitting the tablet.

After the division of the tablet is completed, the handle 404 is pulled back to the initial state, the sliding rod 401 slides upward, the cutting mechanism moves upward under the drive of the sliding rod 401, and the transmission mechanism 5 moves upward under the driving of the sliding rod 401; Driven by the mechanism 5, it returns to the initial state to release the clamping of the tablet. At the same time, the second connecting plate 503 drives the elastic plate 602 to move upward through the cooperation of the slot 506 and the triangular block 603, and the elastic plate 602 drives the medicine blocking plate 601 to move upward. The guide rod 604 slides upwards; after the medicine blocking plate 601 slides upwards to a certain height, the blocking of the tablets is released, and the divided tablets continue to slide down to the medicine outlet 12 along the slideway 11, and the divided medicine tablets fall through the medicine outlet 12. Complete the collection in the lower drawer 13; the fifth spring 605 is compressed when the baffle plate moves upward, and the baffle plate drives the triangular reset block 607 to contact the baffle piece 803 on the top of the guide rod 604. 803 exerts force on the triangular reset block 607, and the triangular reset block 607 moves away from the second connecting plate 503. The triangular reset block 607 drives the deformation of the elastic plate 602, and the elastic plate 602 drives the triangular block 603 to separate from the slot 506. Under the action of the elastic force of five springs 605, the medicine retaining plate 601 slides down to reset along the guide bar 604, waiting for the next division.

The invention is simple in structure and convenient in operation, and effectively realizes arbitrary switching of different equal portions of tablets of various sizes. At the same time, the tablets are divided evenly, which meets the needs of children with different weights for the dosage. The tablet division speed is fast and the efficiency is high. Improve the work efficiency of medical staff and ensure the safety of patients taking medicine.
