[0002] As is well known, pharmaceuticals are substances or preparations used to prevent, treat, or diagnose diseases in humans and livestock. Drugs are classified by their source into natural drugs and synthetic drugs. Medicines can also prevent or treat diseases, reduce suffering, improve health, enhance the body's resistance to disease, or aid in the diagnosis of diseases. Granulation in the pharmaceutical manufacturing process is a technique that improves powder flowability by agglomerating finer particles into coarser granules. Almost all solid dosage forms require granulation, and the resulting granules may be the final product, such as granules.

[0003] Utility model patent CN202220680376.1 discloses a rapid granulation device, relating to the technical field of pharmaceutical processing equipment. The device includes a granulation box, a rapid granulation mechanism at the top of the granulation box, and a debris recovery mechanism at the bottom of the granulation box. The rapid granulation mechanism includes a welding block, which is fixedly welded to the outer wall of the granulation box. A fixing frame is fixedly installed on the top of the welding block, and an electric push rod is fixedly installed on the inner wall of the fixing frame.

[0004] This invention pre-adds the pharmaceutical raw materials into the inner cavity of the granulation box, then controls the electric push rod to extend, driving the sealing push plate to slide down in the inner cavity of the granulation box, thereby extruding the pharmaceutical raw materials in strip form through the through hole in the inner cavity. At the same time, the drive motor is controlled to work, driving the cutting blade holder to rotate and cut the strip-shaped pharmaceutical raw materials, thus completing the granulation process of the medicine and shortening the granulation processing time of the medicine.

[0005] However, the granulation plate of this equipment is welded, which limits the size of the generated drug particles and reduces its applicability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figs. 1-3 This application proposes a granulation device for pharmaceutical processing according to this embodiment, including a crushing chamber 1, a feed inlet 2 at the top of the crushing chamber 1 for feeding raw materials; a conveying chamber 3 horizontally connected to the bottom of the crushing chamber 1, a discharge port 4 at the lower right end of the conveying chamber 3, a discharge plate 5 fixed at the discharge port 4 by bolts, and a plurality of discharge holes 6 evenly opened on the discharge plate 5; a discharge chamber 7 at the bottom of the conveying chamber 3 corresponding to the discharge holes 6, and a straight cutter 9 driven by a first motor 8 in the discharge chamber 7 corresponding to the discharge holes 6, for cutting the extruded material into granules.

[0022] Furthermore, two interlocking crushing rollers 10 are arranged laterally inside the crushing chamber 1. The two ends of the two crushing rollers 10 are respectively rotatably set on the left and right side walls inside the crushing chamber 1. One end of each of the two crushing rollers 10 is provided with a gear 11, and the two gears 11 mesh with each other. The other end of one of the crushing rollers 10 is driven by an external drive device, which can be a conventional drive device. This design allows the two crushing rollers 10 to cooperate with each other to perform efficient preliminary crushing of the raw materials.

[0023] To improve material feeding efficiency, a conical feeding trough 13 is provided at the bottom of the crushing chamber 1, corresponding to the connection with the conveying chamber 3. The design of the conical feeding trough 13 allows the crushed material to enter the conveying chamber 3 smoothly, avoiding material accumulation.

[0024] Furthermore, an auger 14 is provided laterally inside the conveying chamber 3. The two ends of the auger 14 are respectively rotatably located at the left and right ends of the conveying chamber 3. A second motor 15 is provided at the left end of the conveying chamber 3 corresponding to the auger 14 to drive its rotation. The auger 14 rotates under the drive of the second motor 15, which can further crush and mix the materials and convey them to the discharge port 4.

[0025] To facilitate material discharge, a discharge channel 16 is provided in the discharge chamber 7 corresponding to the discharge hole 6. The design of the discharge channel 16 not only facilitates material discharge but also facilitates the replacement of the discharge plate 5, thereby improving the applicability and flexibility of the device.

[0026] In addition, an inspection port 17 is provided on the left side of the discharge chamber 7, and a cover plate 12 is hinged to the inspection port 17. The design of the inspection port 17 facilitates the inspection and replacement of the cutter 9, ensuring the normal operation of the device.

[0027] When using this pharmaceutical granulation device, the raw material is first fed into the crushing chamber 1 through the feed inlet 2. After initial crushing by two crushing rollers 10, the material enters the conveying chamber 3 through the conical feed chute 13. In the conveying chamber 3, the auger 14 further crushes and mixes the material and conveys it to the discharge outlet 4. The material is squeezed into strips through the discharge holes 6 on the discharge plate 5 and then enters the discharge chamber 7. In the discharge chamber 7, the straight cutter 9 cuts the strip material into granules and finally discharges them through the discharge channel 16. If it is necessary to replace the discharge plate 5 with a different size discharge hole 6, simply remove the bolts and replace the discharge plate 5. If it is necessary to repair or replace the cutter 9, simply open the cover plate 12 of the inspection port 17 to carry out the operation.

[0028] In summary, the granulation device for pharmaceutical processing of this invention can effectively meet the needs of pharmaceutical processing. Through its reasonable structural design, it achieves efficient crushing, mixing, conveying, and granulation of raw materials, while also possessing high applicability and flexibility.
