[0013] In one of the embodiments, the pulverizing box is provided with a guide block surrounding the opening end, and the guide block is used for guiding the medicine into the pulverizing box.

[0014] In one of the embodiments, the mounting rack is provided with an elastic buffer, and the mounting rack, the elastic buffer and the vibrating disc are sequentially connected.

[0015] In one of the embodiments, the pulverizing box comprises an upper box body and a lower box body, the lower box body is located below the upper box body and detachably connected with the upper box body; the lower box body has a first collecting cavity, and the first screen is arranged between the upper box body and the first collecting cavity of the lower box body.

[0016] In one of the embodiments, the pulverizing driving mechanism is a push rod mechanism, and the pulverizing mechanism comprises a top plate, a protruding block and a connecting rod.

[0017] The top plate is located outside the pulverizing cavity, the output end of the push rod mechanism is in driving connection with the top plate; the protruding block is located in the pulverizing cavity, the pulverizing box is provided with a mounting through hole penetrating through the cavity wall of the pulverizing cavity, one end of the connecting rod is connected with the top plate, the other end of the connecting rod passes through the mounting through hole and is connected with the protruding block, and the protruding block is used for cooperating with the inner bottom wall of the pulverizing cavity to extrude the tablets.

[0018] In one of the embodiments, one end of the connecting rod located outside the pulverizing box is sleeved with a reset spring, and the top plate, the reset spring and the pulverizing box are sequentially connected.

[0019] In one of the embodiments, a side wall of the pulverizing box is provided with a plug hole, a plug plate is detachably plugged in the plug hole, and the top wall of the plug plate is the inner bottom wall of the pulverizing cavity.

The part of the collection plate located outside the second collection chamber is provided with an easy-pull ring.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The detachable grinding chamber design facilitates the removal of residual material from the grinding chamber, avoiding the hassle of rummaging through narrow and complex structures and improving work efficiency. Furthermore, it allows for thorough cleaning and maintenance of the grinding chamber. Since powder inevitably accumulates inside, the detachable design ensures cleanliness and prevents residue buildup, guaranteeing the accuracy and stability of subsequent grinding operations.

[0025] 2. By connecting the pulverizing mechanism inside the pulverizing chamber, the pulverizing drive mechanism located outside the chamber does not come into contact with the tablets, thus preventing contact between the drive mechanism and tablet powder. During cleaning, the pulverizing mechanism can be easily removed along with the pulverizing chamber, effectively controlling the potential contamination from tablet powder within the relatively independent module of the pulverizing chamber and its internal pulverizing mechanism. Subsequent cleaning and maintenance of the pulverizing drive mechanism is greatly simplified; only routine wiping and maintenance of key transmission parts are required to ensure it remains in good working order, ready to handle the next round of high-intensity pulverizing tasks, providing a solid guarantee for the efficient and stable progress of the pharmaceutical processing flow.

[0026] 3. A vibratory feeder and a vibratory motor are used as the pulverizing drive mechanism, and a first screen and grinding balls are used as the pulverizing mechanism. When the vibratory feeder is driven by the vibratory motor to vibrate violently, the energy of the vibration is transferred to the pulverizing chamber, causing the grinding balls to be forcefully thrown and rolled at high speed within the pulverizing chamber. During this process, the grinding balls collide violently with the tablets, are continuously squeezed, and experience high-frequency friction, thereby continuously pulverizing the tablets until they are made into fine powder that can pass through the first screen and leave the pulverizing area of ​​the grinding balls.

[0027] 4. A pusher mechanism is used as the pulverizing drive mechanism. Through cooperation with the top plate, protrusions, and connecting rods, the tablets positioned between the protrusions and the inner bottom wall are repeatedly compressed. On one hand, this repeated compression disperses the extrusion force, preventing damage to the equipment caused by high-intensity compression and impacts. For example, the peak stress on the connecting rod is significantly reduced, decreasing the risk of breakage and deformation, lowering maintenance costs, and extending equipment life. On the other hand, it improves the uniformity of pulverization. The tablets are subjected to uniform force, gradually becoming finer, resulting in a finer and more uniform powder.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] First embodiment:

[0038] See Figure 1 The first embodiment of the present invention includes a pharmaceutical tablet pulverizer for analysis, comprising a mounting frame 1, a pulverizing drive mechanism 2, and at least one pulverizing box 3.

[0039] The pulverizing drive mechanism 2 is mounted on the mounting frame 1. The pulverizing box 3 has a pulverizing chamber 31 and an opening 32 communicating with it. The pulverizing box 3 is detachably connected to the pulverizing drive mechanism 2. After the pulverizing task is completed, the operator can remove the pulverizing box 3 from the pulverizing drive mechanism 2. On the one hand, this facilitates the removal of residual material in the pulverizing chamber 31, avoiding the hassle of difficult material retrieval in a narrow and complex connection structure, thus improving work efficiency. On the other hand, it facilitates deep cleaning and maintenance of the pulverizing box 3. The inside of the pulverizing box 3 inevitably contains residual tablet powder. The detachable pulverizing box 3 facilitates the cleaning of residual tablet powder, ensuring that no material residue remains for the next use, thereby ensuring that the accuracy and stability of subsequent pulverizing operations are not affected by residual impurities. Preferably, the detachable connection is a snap-fit ​​connection, allowing the pulverizing box 3 to be quickly removed after pulverization by engaging the snap-fit ​​mechanism.

[0040] The pulverizing box 3 is connected to the pulverizing mechanism 4 located in the pulverizing chamber 31. The pulverizing drive mechanism 2 is connected to the pulverizing mechanism 4 so that the pulverizing mechanism 4 can pulverize the tablets located in the pulverizing chamber 31.

[0041] In use, the operator places the tablets to be pulverized into the pulverizing chamber 31 of the pulverizer 3, and fixes the pulverizer 3 on the mounting frame 1. The pulverizing drive mechanism 2 is then started. The pulverizing drive mechanism 2 directly or indirectly drives the pulverizing mechanism 4 to pulverize the tablets. After completion, the pulverizer 3 and the pulverizing mechanism 4 inside the pulverizer 3 are removed. A new pulverizer 3 and a new pulverizing mechanism 4 are then used to start a new round of pulverizing tasks. At the same time, after removing the pulverizer 3 and taking out the pulverized tablet powder, the pulverizer 3 and the pulverizing mechanism 4 are cleaned and dried in preparation for the next round of tablet pulverizing.

[0042] Specifically, because the powder produced after tablet crushing is extremely fine and has a certain degree of stickiness, if the crushing drive mechanism 2 and the crushing mechanism 4 are integrally fixedly connected, the powder can easily get into the gaps, bearings, gears, and other critical and precision parts of the drive mechanism. This will not only affect the transmission efficiency of the drive mechanism, causing power transmission obstruction and equipment malfunction, but also significantly increase the difficulty of cleaning. Cleaning requires a lot of time and effort, and the inability to completely remove the powder may leave residual hygiene hazards in the equipment, endangering the quality of subsequent tablet crushing.

[0043] Based on this, the pulverizing mechanism 4 is connected inside the pulverizing box 3, ensuring that the pulverizing drive mechanism 2, located outside the pulverizing box 3, does not come into contact with the tablets, thus preventing contact between the drive mechanism and the tablet powder. During cleaning, the pulverizing mechanism 4 can be easily removed along with the pulverizing box 3, effectively controlling the potential contamination from the tablet powder within the relatively independent module of the pulverizing box 3 and its internal pulverizing mechanism 4. Subsequent cleaning and maintenance of the pulverizing drive mechanism 2 is greatly simplified; only routine wiping and maintenance of key transmission parts are required to ensure it remains in good working order, ready to handle the next round of high-intensity pulverizing tasks, providing a solid guarantee for the efficient and stable progress of the pharmaceutical processing flow.

[0044] Preferred, such as Figure 1 and Figure 2 As shown, the crushing drive mechanism 2 includes a vibratory plate 21 and a vibratory motor 22. The vibratory plate 21 is movably mounted on the mounting frame 1, and the vibratory motor 22 is mounted on the vibratory plate 21. The crushing box 3 is detachably connected to the vibratory plate 21. When the vibratory motor 22 is powered on and started, according to the principle of electromagnetic induction, the rotor inside the vibratory motor 22 rotates at high speed, driving the eccentric block to generate periodic centrifugal force, thereby enabling the vibratory plate 21 to obtain high-frequency and stable vibration energy, and vibrate violently at a specific frequency and amplitude.

[0045] The grinding mechanism 4 includes multiple grinding balls 41 and at least one first screen 42. Preferably, the grinding balls 41 have high hardness and density, and a stable structure that will not chemically react with the tablets. The first screen 42 is disposed inside the grinding chamber 31, and the multiple grinding balls 41 are disposed inside the grinding chamber 31 and supported by the first screen 42. When the vibrating disk 21 is driven by the vibrating motor 22 to vibrate violently, the vibration energy is transferred to the grinding box 3, causing the grinding balls 41 to be forcefully thrown and rolled at high speed inside the grinding chamber 31. During this process, the grinding balls 41 collide violently with the tablets, continuously squeeze them, and experience high-frequency friction, thereby continuously grinding the tablets and quickly turning them into fine powder. The powder can then pass through the first screen 42 and leave the grinding area of ​​the grinding balls 41. Compared to the low-speed grinding in the prior art, the pulverizing mechanism 4 can complete the grinding of the tablets in a shorter time, greatly reducing the grinding time required. For example, compared to the prior art of grinding tablets with a regular mortar and pestle, the high-speed vibration energy generated by the vibratory mill can more quickly destroy the integrity of the tablet structure, making it easier to grind the tablets into fine powder and greatly improving the efficiency of drug grinding.

[0046] Preferred, such as Figure 2 As shown, the grinding box 3 is provided with a guide block 33 surrounding the opening 32. The guide block 33 is used to guide the medicine into the grinding box 3 to prevent the tablets from accumulating at the edge of the opening 32, which would result in insufficient medicine content entering the grinding box 3 and affect the grinding effect.

[0047] The mounting frame 1 is equipped with an elastic buffer 11, and the mounting frame 1, the elastic buffer 11, and the vibratory disk 21 are connected in sequence. When the crushing drive mechanism 2 is working, the vibratory disk 21 will generate high-frequency and violent vibrations. The elastic buffer 11 is placed between the mounting frame 1 and the vibratory disk 21. Through its elastic deformation characteristics, it can effectively absorb the vibration energy transmitted from the vibratory disk 21, preventing the vibration from being directly transmitted to the mounting frame 1 and the external environment.

[0048] The pulverizing box 3 includes an upper box body 34 and a lower box body 35. The lower box body 35 is located below the upper box body 34 and is detachably connected to the upper box body 34. The lower box body 35 has a first collection chamber 36, and a first screen 42 is disposed between the upper box body 34 and the first collection chamber 36 of the lower box body 35. Specifically, during the pulverizing process, after the tablets are pulverized, the powder particles that meet the required size can pass through the first screen 42 and enter the first collection chamber 36 of the lower box body 35, while larger tablet fragments remain in the upper box body 34 to continue pulverizing. This not only improves the accuracy of pulverization, making the final powder particle size more uniform, but also avoids over-pulverization, reduces energy consumption, and improves production efficiency. At the same time, after the tablets are pulverized, the upper box body 34 and the lower box body 35 can be separated to obtain most of the tablet powder in a fine powder form, which is convenient for operators to collect.

[0049] Second embodiment:

[0050] Please see Figure 3 It shows a pharmaceutical tablet pulverizer for analysis provided in the second embodiment of this application, which differs from the first embodiment described above in that:

[0051] The crushing drive mechanism 2 is a push rod mechanism 23. Preferably, the push rod mechanism 23 can be an electric push rod mechanism 23, a hydraulic push rod mechanism 23, or a pneumatic push rod mechanism 23. The crushing mechanism 4 includes a top plate 43, a protrusion 44, and a connecting rod 45.

[0052] See Figure 4 Preferably, the top plate 43 is located outside the crushing chamber 31, and the output end of the push rod mechanism 23 is driven to be connected to the top plate 43; the protrusion 44 is located inside the crushing chamber 31, and the crushing box 3 is provided with a mounting through hole 37 that penetrates the cavity wall of the crushing chamber 31. One end of the connecting rod 45 is connected to the top plate 43, and the other end of the connecting rod 45 passes through the mounting through hole 37 and is connected to the protrusion 44. The protrusion 44 is used to cooperate with the inner bottom wall of the crushing chamber 31 to squeeze the tablet.

[0053] When the crushing device is started, the push rod mechanism 23, which is driven and connected to the top plate 43, repeatedly pushes the top plate 43. After the top plate 43 is subjected to force, it drives the connecting rod 45 to move. The connecting rod 45 transmits the movement of the top plate 43 to the protrusion 44, so that the protrusion 44 moves vertically towards the inner bottom wall of the crushing chamber 31 along the guide of the mounting through hole 37, and together with the inner bottom wall of the crushing chamber 31, repeatedly squeezes the tablet between the protrusion 44 and the inner bottom wall.

[0054] On the one hand, the repeated extrusion of the pulverizing device disperses the extrusion pressure, avoiding damage to the equipment caused by high-intensity extrusion and collision. For example, the peak stress on the connecting rod 45 is significantly reduced, decreasing the risk of breakage and deformation, lowering maintenance costs, and extending equipment life. On the other hand, it improves the uniformity of pulverization. The tablets are subjected to uniform force, gradually becoming finer, resulting in a finer and more uniform final powder.

[0055] Preferably, a return spring 46 is fitted onto the end of the connecting rod 45 outside the crushing box 3, and the top plate 43, the return spring 46, and the crushing box 3 are connected in sequence. After the push rod mechanism 23 pushes the top plate 43 to complete one pressing action, the return spring 46 quickly rebounds due to its own elasticity, assisting the top plate 43 to return to its original position and preparing for the next pressing. This makes the entire crushing process smoother, reduces equipment operation interruptions and impacts, and ensures continuous and stable crushing operations. At the same time, the return spring 46 can also absorb excess energy during the movement of the top plate 43, effectively buffering the impact force generated by sudden acceleration or deceleration, preventing the impact force from being directly transmitted to the crushing box 3 and other connected components, reducing the probability of component damage due to vibration and collision, and further extending the overall service life of the equipment.

[0056] Preferably, the side wall of the pulverizing box 3 has an insertion hole, into which an insert plate 5 is detachably inserted. The top wall of the insert plate 5 is the inner bottom wall of the pulverizing chamber 31. The pulverizing box 3 has a collection chamber located directly below the insert plate 5, and the bottom wall of the insert plate 5 is the top wall of the second collection chamber 39. After the tablet pulverization operation is completed, the insert plate 5 is removed, and the drug powder falls into the second collection chamber below, thereby completing the collection of the crushed tablet powder.

[0057] Preferably, the wall of the second collecting chamber 39 is connected to a second screen 38, which is located at the top of the second collecting chamber 39. The powder falling from the crushing chamber 31 first passes through the second screen 38. Larger powder particles are intercepted and crushed again, while powder that can pass through the screen is collected at the bottom of the second collecting chamber 39.

[0058] Preferably, the side wall of the pulverizing box 3 is also provided with a collection port that connects to the second collection chamber 39. A collection plate 6 is sleeved on the collection port. The part of the collection plate 6 located inside the second collection chamber 39 is provided with a collection groove 61. The collection groove 61 is used to collect the tablet powder after passing through the second screen 38. The part of the collection plate 6 located outside the second collection chamber 39 is provided with an easy-pull ring 62. By simply pulling the easy-pull ring 62, the collection plate 6 can be easily removed, completing the collection of most of the drug powder. Moreover, the detachable collection plate 6 can be removed and cleaned at any time, effectively preventing drug powder residue from deteriorating and contaminating subsequent batches of drug powder, effectively ensuring the hygiene standards of drug production, and maintaining the long-term stable performance of the pulverizing device.
