DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objectives, technical solutions and beneficial effects clearer and more specific, the present invention is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, the pharmaceutical granulator includes a base 1, a control cabinet 4, a rotating shaft 5, a granulation bin 6, and a recovery bin 13;

[0026] The top surface of the base 1 is provided with a control cabinet 4 and a recovery bin 13 in parallel. The front surface of the control cabinet 4 is provided with a door body, which is convenient for overhauling the internal equipment of the control cabinet 4. The bottom surface of the base 1 is provided with a support foot 2, and the bottom surface of the support foot 2 is connected with a universal wheel 3, which is convenient for transporting the entire equipment to a designated position. A granulation bin 6 is provided on the side of the control cabinet 4, and the granulation bin 6 is connected to the control cabinet 4 through a rotating shaft 5. The top surface of the granulation bin 6 is connected to a mixing bin 8, and a crushing roller 9 is provided inside the mixing bin 8. The bottom of the granulation bin 6 is connected to a feeding port 12, and the front surface of the granulation bin 6 is connected to a hatch through a hinge. The setting of the hatch is convenient for cleaning and overhauling the interior of the granulation bin 6 A hob 15 is provided inside the granulation bin 6, and a driving mechanism is provided inside the control cabinet 4. The driving mechanism is used to drive the hob 15 to rotate. The driving mechanism includes a motor 22, a reducer 23, a transmission belt 24, etc. The driving mechanism is a common driving mechanism in the prior art. The driving mechanism is used to drive the rotating shaft 5 to rotate, thereby driving the hob 15 to rotate. Rotating bearings 10 are provided on both sides of the hob 15. A blade 16 is provided on the outer surface of the hob 15. The hob 15 rolls and cuts to perform a granulation operation. A partition screen 17 is provided inside the granulation bin 6. The partition screen 17 can perform preliminary screening of the granulated material, and the material with a qualified particle size leaks out from the discharge port 12;

[0027] A recovery bin 13 is provided just below the discharge port 12. The recovery bin 13 recovers the material leaking out of the granulation bin 6 after granulation. A bottom wheel 14 is provided at the bottom of the recovery bin 13 to facilitate the transportation of the recovery bin 13. A support plate 19 is provided inside the recovery bin 13. A mesh slot 20 is placed on the top surface of the support plate 19. A side plate 21 is provided on the side of the top surface of the mesh slot 20.

The mesh slot 20 can screen the drug particles again, and the drug particles with the required particle size are recovered inside the mesh slot 20.

[0028] When the pharmaceutical granulator is used for the preparation of drug granules, the entire equipment is transported to the designated location, and the material is fed from the feed port 7 for drug granulation. The granulated material enters the mixing bin 8 for the first cutting and granulation. The material after the first cutting enters the granulation bin 6 for cutting and granulation again. A rolling device is provided inside the granulation bin 6, and the material is rolled into the recovery bin 13 through a pipeline for recovery. The material is recovered into the mesh slot 20, and the material that meets the particle size is stored in the mesh slot 20. The particles or powder with a small particle size are sieved out from the mesh slot 20, and the sieved material is left outside the mesh slot 20. In the recovery bin 13, the mesh slot 20 is lifted out from the side plate 21 of the mesh slot 20, and the drug granules that meet the requirements in the mesh slot 20 are recovered. At the same time, the residual material inside the recovery bin 13 is cleaned, and the residual material inside the granulation bin 6 is cleaned from the bin door 11. The operation is convenient.
