Existing equipment for these processes, such as rounding and polishing, is separate and unsuitable for automated operation. This is particularly difficult to achieve with the diverse specifications and small batch sizes of pills produced. Improvements are needed to increase production efficiency and meet the demands of small-batch, diverse processing. Utility Model Content

Mechanism 3 includes a screw extrusion mechanism 31, a pelletizing mechanism 32, and a receiving trough 33. The screw extrusion mechanism 31 is equipped with a drug feed hopper 34. The pelletizing mechanism 32 is equipped with two relatively rotating pelletizing rollers 321. The output end of the screw extrusion mechanism 31 is provided with a discharge hole. The drug strips extruded through the discharge hole enter the pelletizing rollers 321 and are cut into pellets. The pellets fall through the receiving trough 33 into the rounding mechanism 2 for rounding. The rounded pills fall into the receiving bin 12 for collection. The receiving bin 12 is equipped with a screen 18, and a scrap recovery box is located below the screen 18.
[0023] The rounding mechanism 2 includes a spiral rounding roller 21 and an intermittent discharge baffle 22. Two intermittent discharge baffles 22 are symmetrically located at the bottom of the rounding hopper 14 and are each connected to a discharge drive mechanism (such as a cylinder or motor-driven reciprocating mechanism) within the chassis 1. The upper end of the spiral rounding roller 21 is detachably connected to the drive motor within the chassis 1 via a rotating shaft 23. The granulating roller 321 is replaceably arranged in the granulating mechanism 32, and the granulating roller 321 is provided with a granulating groove matching the diameter of the pills. The granulating groove in the granulating roller 321 is set according to the size of the granulated pills, and the granulating rollers 321 of different specifications can be replaced according to the size of the pills; the spiral rounding roller 21 is provided with a rounding groove matching the diameter of the pills, and the spiral rounding roller 21 can be replaced with rounding grooves of different specifications according to the size of the pills; during rounding, the intermittent discharge baffle 22 seals the bottom of the round hopper 14, and the pills roll upward from the bottom of the round hopper 14 through the rounding groove in the spiral rounding roller 21, roll to the top of the spiral rounding roller 21, and then fall to the bottom of the round hopper 14 for continuous reciprocating circulation; after a batch of pills are rounded, the intermittent discharge baffle 22 moves to both sides under the drive of the discharge drive mechanism, and the pills fall from the round hopper 14 into the receiving box 12.
[0024] The screw conveying rod in the screw extrusion mechanism 31 is connected to the extrusion motor 36 through a coupling 35. Two symmetrically arranged support mounting seats 16 are installed between the granulation mechanism 3 and the mounting side plate 15, and the two support mounting seats 16 are fixedly connected to the mounting side plate 15 through positioning bolts 17.
[0025] Working principle of this utility model:
[0026] Put the raw materials into the medicine feed hopper 34, open the control box 11 and start the equipment. The screw extruder 31 extrude the raw materials into strips and convey them to the granulator 32. The two relatively rolling granulator rollers 321 in the granulator 32 cut the medicine strips into granules. The granules fall into the round hopper 14 through the receiving chute 33 (the intermittent discharge baffle 22 seals the round hopper 14 at this time). After cutting a batch of materials, the granulator 3 stops granulating. Then the driving motor in the chassis 1 drives the spiral roller 21 to rotate through the rotating shaft 23. The pills are continuously rolled upward from the bottom of the round hopper 14 through the rounding groove in the spiral rounding roller 21, and then fall to the bottom of the round hopper 14 after rolling to the top of the spiral rounding roller 21, and the cycle repeats continuously. After a batch of pills in the round hopper 14 are rounded, the discharging drive mechanism controls the intermittent discharging baffle 22 to move away from the bottom of the round hopper 14, and the pills fall from the round hopper 14 into the receiving box 12, and then fall onto the screen 18 for screening. The crushed material recovery box below the screen 18 will recover the crushed pills and powder.
