[0002] Traditional Chinese Medicine (TCM) is a traditional Chinese medicine system primarily composed of herbs derived from plants, animals, and minerals. It encompasses a variety of herbs, prescriptions, and treatments based on the principles of Traditional Chinese Medicine (TCM) to regulate the body and treat illnesses.

[0003] A drug substance grinder, also known as a Chinese medicine grinder or medicinal material grinder, is used to finely grind raw Chinese medicine ingredients. This equipment is crucial for improving the efficacy of Chinese medicine and facilitating the preparation of Chinese medicine preparations. Drug substance grinders are widely used in the Traditional Chinese Medicine industry, pharmaceutical companies, and Chinese medicine research institutes.

[0004] Currently common API grinders have some shortcomings: on the one hand, when grinding existing Chinese medicinal materials, most of them are placed in a grinding disk and ground in a garlic-pounding manner using a handheld grinding roller. However, this grinding method makes it difficult to fully grind the API, resulting in uneven particle size and affecting the quality of the medicine. On the other hand, for APIs with different particle size requirements, existing grinders lack flexibility in the unloading and screening processes, making it difficult to quickly adjust the filter aperture according to different needs, resulting in low API processing efficiency. Therefore, a API grinder is proposed to solve the above problems. Summary of the Invention

[0005] The present invention is to solve the above technical problems and provides a raw material medicine grinder, the purpose of which is to improve the technical problem that traditional grinders are difficult to fully grind the raw materials, resulting in uneven particle size.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a raw material medicine grinder, which includes a base plate 1, and three groups of supporting legs 2 are fixedly connected to the top of the outer wall of the base plate 1, and grinding discs 3 are rotatably connected between the three groups of supporting legs 2. By allowing the grinding disc 3 to rotate between the three groups of supporting legs 2, the grinding roller 55 can grind the internal Chinese medicine while the grinding disc 3 itself will also rotate, so that the grinding effect of the Chinese medicine is better. A unloading component 4 is provided on the inner wall of the bottom end of the grinding disc 3, and a grinding component 5 is provided on the top of the outer wall of the supporting leg 2.

[0023] like Figure 2 As shown, the grinding assembly 5 includes a gear 51, which is rotatably connected to the top of the outer wall of a group of support legs 2. The outer wall of the gear 51 is meshed with the tooth block 56. The meshing between the two allows the operating arm 52 to drive the gear 51 to rotate to engage the grinding disc 3 to rotate synchronously in opposite directions, thereby making the internal grinding effect of traditional Chinese medicine better. Two groups of hinged rods 53 are hinged to the outer walls of the top of the two groups of support legs 2 on the left. The support legs 2 are provided with three groups. The tops of the two groups on the left are directly hinged to the tops of the hinged rods 53, and the hinged rods 53 on the right are fixedly connected to the surface of the operating arm 52. The top of the outer wall of the gear 51 is fixed. It is connected to an operating arm 52, and a hinged rod 53 is fixedly connected to the surface of the operating arm 52. The end of the hinged rod 53 away from the operating arm 52 is hinged to a connecting rod 54, and the end of the connecting rod 54 away from the hinged rod 53 is fixedly connected to a grinding roller 55. When the operating arm 52 rotates, it will synchronously drive the hinged rod 53 on its surface to rotate synchronously around the center of the circle, thereby driving the corresponding connecting rod 54 and the grinding roller 55 to rotate synchronously, so that the bottom end of the grinding roller 55 rotates around the inner wall of the grinding disk 3, so that the Chinese medicine can be ground. The outer wall of the top of the grinding disk 3 is fixedly connected to multiple groups of tooth blocks 56.

[0024] like Figure 3 、 Figure 4As shown, the unloading assembly 4 includes a rotating block 41, and two groups of filter screens 43 are fixedly connected to the outer wall of the top of the rotating block 41. The aperture sizes of the two groups of filter screens 43 are different. By setting two groups of filter screens 43 with different apertures, the filtration can be adjusted according to the particle size of different Chinese medicines to be ground. The rotating block 41 passes through and is rotatably connected to the inner wall of the bottom end of the grinding disc 3. The shielding door 42 and the filter screen 43 are both rotatably connected to the inner wall of the bottom end of the grinding disc 3. The outer wall of the top of the rotating block 41 is fixedly connected to the shielding door 42. The shielding door 42 and the two groups of filter screens 43 rotate around the rotation center point of the rotating block 41, and a discharge chute is provided at the bottom end of the grinding disc 3. The shielding door 42 is in a closed state, so that the discharge chute of the grinding disc 3 can be blocked and closed during grinding.

[0025] like Figure 3 、 Figure 4 As shown, the bottom end of the outer wall of the grinding disc 3 is fixedly connected to a connecting block 44, and the inner wall of the connecting block 44 is elastically connected to a plug rod 46 through a limit spring 45. One end of the limit spring 45 is fixedly connected to the surface of the plug rod 46, and the other end of the limit spring 45 is fixedly connected to the inner wall of the connecting block 44. The function of the limit spring 45 is to automatically reset the position of the plug rod 46 after it is pulled outward. The plug rod 46 passes through and is slidably connected to the inner wall of the connecting block 44. Three groups of through holes are provided on the outer wall of the bottom end of the rotating block 41, and the bottom end of the outer wall of the plug rod 46 is plugged into the inner wall of the through hole. The three groups of through holes at the bottom end of the rotating block 41 correspond to two groups of filter screens 43 and the shielding door 42, respectively, and can be switched between the three groups by plugging into each group of through holes.

[0026] The working principle of the present utility model is as follows: when grinding Chinese medicine, when the operating arm 52 is manually grasped and rotated, the gear 51 and the hinged rod 53 fixed on its surface are driven to rotate synchronously, and the gear 51 is engaged with the tooth block 56 on the outer wall of the top end of the grinding disc 3, so that when the operating arm 52 drives the gear 51 to rotate, the grinding disc 3 can also rotate synchronously in the opposite direction. At the same time, the connecting rod 54 and the grinding roller 55 hinged at one end of the hinged rod 53 away from the operating arm 52 will also move with the rotation of the operating arm 52. When the operating arm 52 rotates around the center of the circle, the connecting rod 54 and the grinding roller 55 are driven to rotate synchronously, so that the bottom end of the grinding roller 55 rotates around the inner wall of the grinding disc 3, and the Chinese medicine placed in the grinding disc 3 is ground. Since the grinding disc 3 itself also rotates between the three groups of support legs 2, the grinding effect of the Chinese medicine is further improved.

[0027] During the grinding process, the shielding door 42 fixed to the top outer wall of the rotating block 41 is closed, blocking the discharge chute at the bottom of the grinding disc 3. When unloading is required, the plug rod 46 is pulled outward, compressing the limit spring 45, causing the plug rod 46 to disengage from the through-hole in the bottom outer wall of the rotating block 41. The rotating block 41 is then rotated, driving the shielding door 42 and the two sets of filter screens 43 to rotate around their rotation center. Two sets of filter screens 43 with different apertures are fixedly connected to the top outer wall of the rotating block 41, allowing for adjustment and filtration according to the particle size required for different Chinese medicines. When the filter screens 43 are rotated to the desired position, the plug rod 46 is released. Under the action of the limit spring 45, the plug rod 46 re-engages with the corresponding through-hole in the bottom outer wall of the rotating block 41, fixing the position of the rotating block 41. At this time, the ground Chinese medicine can be filtered and discharged through the corresponding filter screens 43.
