[0002] In the process of drug manufacturing, it is sometimes necessary to grind or pulverize the drugs to facilitate administration or further preparation, which requires the use of a drug grinding device.
[0003] Currently, common pharmaceutical grinders grind drugs into the machine, then sieve them to remove larger particles. The larger particles are then put back into the machine for further grinding. The ground drugs need to be manually sieved repeatedly and then put back into the grinder. This process is not only very cumbersome, but also extremely inconvenient to clean. Utility Model Content

[0019] 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.
[0020] Please see Figure 1-2 This application proposes a grinding device for pharmaceutical processing provided in this embodiment. The grinding device includes a grinding box 1, a support base 2 fixedly connected to the outer wall of the grinding box 1, the grinding box 1 is a hollow cylindrical shape with openings at the top and bottom, a cover plate 3 is fixed to the top by bolts, a grinding roller 4 is longitudinally rotatably mounted at the bottom of the cover plate 3 and coincides with the central axis of the grinding box 1, and a feed pipe 5 is provided on the side wall of the grinding box 1 corresponding to the grinding roller 4.
[0021] The grinding roller 4 includes a rotating shaft 41 that is rotatably connected to the top of the cover plate 3. The bottom of the rotating shaft 41 is provided with a conical guide block 42. A trapezoidal first grinding zone 43 is fixed on the lower side of the guide block 42. The top of the first grinding zone 43 is the same size as the bottom of the guide block 42. A cylindrical second grinding zone 44 is fixed at the lower end of the first grinding zone 43. The top of the second grinding zone 44 is the same size as the bottom of the first grinding zone 43. This design allows the pharmaceutical raw materials to be smoothly guided into the grinding zone through the conical guide block 42 after entering the grinding box 1 for step-by-step grinding.
[0022] Furthermore, a motor 7 is provided at the top of the cover plate 3 corresponding to the rotating shaft 41 to drive its rotation. The motor 7 drives the grinding roller 4 to rotate through the rotating shaft 41, thereby realizing the grinding of the medicine. This design not only improves the grinding efficiency, but also reduces the tediousness of manual operation.
[0023] The inner wall of the grinding chamber 1, the outer surface of the first grinding zone 43, and the outer surface of the second grinding zone 44 are provided with abrasive layers 8. From the top of the first grinding zone 43 to the bottom of the second grinding zone 44, the roughness of the abrasive layers 8 on the inner wall of the grinding chamber 1, the outer surface of the first grinding zone 43, and the outer surface of the second grinding zone 44 gradually decreases. This design allows the medicine to be gradually refined during the grinding process, avoids the formation of large particles, and improves the grinding effect.
[0024] A screen 9 is fixed to the bottom opening of the grinding box 1 by bolts. The screen 9 is designed to disperse the ground medicine and ensure that the medicine particles do not stick together after grinding. At the same time, the screen 9 is fixed by bolts, which makes it easy to disassemble and clean later.
[0025] Furthermore, a vibration motor 6 is fixedly installed on the outer wall of the grinding chamber 1. The vibration motor 6 enables the grinding chamber 1 to vibrate, thereby further dispersing the ground pharmaceutical raw materials, preventing adhesion, and further improving the grinding effect.
[0026] When using this pharmaceutical grinding equipment, firstly, the cover plate 3 is fixed to the top of the grinding chamber 1 with bolts. The pharmaceutical raw materials are added into the grinding chamber 1 through the feed pipe 5. The motor 7 is started, driving the grinding roller 4 to rotate. The pharmaceutical raw materials are guided through the guide block 42 to the space between the first grinding zone 43 and the inner wall of the grinding chamber 1 for preliminary grinding. Subsequently, the pharmaceutical raw materials enter the second grinding zone 44 for further refinement. The ground pharmaceutical materials are screened through the sieve 9 to ensure that the particles reach the required fineness. The vibration of the vibrating motor 6 can disperse the pharmaceutical raw materials and prevent them from sticking together. After grinding is completed, the cover plate 3 and the sieve 9 are removed by unscrewing the bolts for cleaning.
[0027] In summary, the pharmaceutical grinding equipment of this utility model achieves efficient grinding and screening of pharmaceuticals through a reasonable structural design. The step-by-step grinding design avoids the occurrence of large particles and improves the grinding effect. The combined use of the screen 9 and the vibrating motor 6 further improves the grinding efficiency and pharmaceutical quality. The detachable design of the cover plate 3 and the screen 9 makes the cleaning of the equipment more convenient and reduces the workload of the operators. It has high practical value and promising prospects for promotion.
