Abstract
Description
Technical Field
[0001] This utility model relates to the field of drug grinding technology, specifically to a drug grinding device. Background Technology
[0002] Grinding drugs has many advantages, mainly related to improving efficacy, facilitating formulation, and aiding storage. For example, grinding can reduce the size of drug particles, increase the contact area between the drug and the dissolution medium, accelerate drug dissolution, and allow the human body to absorb the drug more fully, thereby improving the bioavailability of the drug. Moreover, smaller drug particles can be absorbed into the bloodstream more quickly, thus accelerating the speed at which the drug takes effect. Furthermore, the fluidity and compressibility of ground drug powder are better, making it easier to formulate various dosage forms, such as tablets, capsules, and powders.
[0003] Although drug grinding has many advantages, existing drug grinding equipment sometimes causes some drugs to remain stationary during grinding when grinding viscous or prescription drugs. However, some of the drugs that move with the rotation of the blades form agglomerates. Agglomerates result in insufficient grinding uniformity, which in turn affects the quality of subsequent formulations.
[0004] Therefore, how to thoroughly grind the drug to avoid particle agglomeration and inconsistent uniformity is a problem that needs to be solved. Utility Model Content
[0005] In view of this, the present invention provides a drug grinding device, which uses a rotating handle to make the swinging component swing with the grinding component, causing the drug to shake in the grinding jar, so that it can fully contact the blade through shaking, making the drug more evenly distributed in the grinding jar and improving the grinding effect.
[0006] To address the aforementioned technical problems, this utility model provides a drug grinding device, including a support base, a swing assembly, and a grinding assembly mounted on the swing assembly. The swing assembly and the support base are connected via a rotating shaft. The swing assembly includes a swing arm disposed on one side of the rotating shaft, with a support plate fixed to the bottom of the swing arm. The grinding assembly is mounted on the top of the support plate via a connector. Specifically, by connecting the grinding assembly to the support plate via the connector, the grinding assembly can be swung by the swing assembly when grinding the drug. This swaying motion provides different angles for grinding, expanding the grinding range. Furthermore, when the drug clumps together, the swaying motion disperses the clumps onto the blades, preventing the clumps from affecting the uniformity of grinding.
[0007] A rotating shaft passes through the support base, and symmetrical limit blocks are arranged on the rotating shaft to restrict its movement. These limit blocks are located on both sides of the support base. In other words, the limit blocks ensure stable rotation of the rotating shaft on the support base, preventing axial movement during use. This ensures the stability of the oscillating component when it oscillates around the rotating shaft, making the device operate more stably and reducing potential malfunctions and poor grinding results caused by axial movement of the rotating shaft.
[0008] A counterweight is connected to the other side of the rotating shaft, and a handle for easy operation is attached to the counterweight. That is, the weight of the swing component is balanced by the counterweight, making the swing process more stable and reducing swaying caused by the shift of the center of gravity; the swing angle of the swing component can be flexibly controlled by the handle, and the position and angle of the swing component can be adjusted at any time according to actual needs, increasing the flexibility of the device.
[0009] The grinding assembly includes a grinding jar, the top of which abuts against a cover plate, and a grinding motor is mounted on the top of the cover plate. The cover plate seals the grinding jar, preventing medication from splashing out during grinding, ensuring operator safety and a clean environment; while the grinding motor provides power for the grinding operation, allowing the medication to be ground within the grinding jar.
[0010] The output shaft of the grinding motor is connected to a rotating shaft via a coupling, and a cutting tool for grinding the medicine is fixedly mounted at the bottom of the rotating shaft. That is, the rotating shaft is connected to the output shaft of the grinding motor via a coupling to ensure the stability of power transmission. The stable rotation enables the cutting tool to rotate at high speed under the drive of the motor, thereby grinding the medicine in the grinding jar and achieving the pulverization and refinement of the medicine.
[0011] The rotating shaft is also equipped with a scraper, which is used to scrape the medicine on the tank wall, and the scraper is located at the top of the blade. That is, the scraper scrapes off the medicine that adheres to the tank during the grinding process, so that the medicine returns to the grinding area, ensuring the uniformity and thoroughness of the medicine grinding, improving grinding efficiency while avoiding waste of medicine.
[0012] The connector includes a support plate and threaded holes at the bottom of the grinding jar, as well as screws that connect the support plate and the grinding jar through the threaded holes. That is, the connection method using threaded holes and screws allows for a detachable connection between the grinding assembly and the support plate in the oscillating assembly, facilitating the installation, disassembly, and replacement of the grinding assembly. It also facilitates cleaning, maintenance, or tool replacement operations on the grinding jar, improving the maintainability and practicality of the device.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0014] 1. The swing assembly and the support base are connected by a rotating shaft. The grinding assembly is installed on the swing assembly, which allows the swing assembly to swing around the rotating shaft, thereby driving the grinding assembly to move. This helps to expand the grinding range and realize grinding operations at multiple angles and positions.
[0015] 2. The rotating shaft passes through the support base, and symmetrical limit blocks are set on the shaft body. The limit blocks are located on both sides of the support base to restrict the movement of the rotating shaft, ensuring the stability and reliability of the swing assembly when swinging around the rotating shaft, and reducing the problems of failure and poor grinding effect caused by the movement of the rotating shaft.
[0016] 3. A scraper is installed on the shaft at the top of the cutter, which can scrape off the medicine adhering to the wall of the grinding jar during the grinding process, so that the medicine can return to the grinding area, ensuring the uniformity and thoroughness of the medicine grinding and avoiding medicine waste.
[0017] 4. The connecting parts are connected by threaded holes in the tray and the bottom of the grinding jar, and screws are used to achieve a detachable connection between the grinding assembly and the tray in the swing assembly. This facilitates the installation, disassembly and replacement of the grinding assembly, and makes it easy to clean, maintain or replace the grinding jar or the cutting tools.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0024] like Figure 1-4 As shown: This embodiment provides a drug grinding device, including a support base 100, a swing assembly 400, and a grinding assembly 500 mounted on the swing assembly 400. The swing assembly 400 is connected to the support base 100 via a rotating shaft 200. The swing assembly 400 includes a swing arm 401 disposed on one side of the rotating shaft 200, with a support plate 402 fixedly mounted at the bottom of the swing arm 401. The grinding assembly 500 is mounted on the top of the support plate 402 via a connector 300. The swing assembly 400 includes a swing arm 401, with a support plate 402 at the bottom of the swing arm 401, and the grinding assembly 500 is mounted on the top of the support plate 402 via the connector 300. This structure allows the swing assembly 400 to swing around the rotating shaft 200, thereby driving the grinding assembly 500 mounted thereon to swing, providing different angles and methods for drug grinding. This allows the grinding assembly 500 to achieve a swing function through the swing assembly 400, increasing the flexibility and versatility of the grinding process and improving the effect of drug grinding.
[0025] A rotating shaft 200 passes through a support base 100, and symmetrically arranged limit blocks 201 are positioned on the rotating shaft 200 to restrict its movement. The limit blocks 201 are located on both sides of the support base 100. The limit blocks 201 restrict the movement of the rotating shaft 200, ensuring that it can only rotate around its own axis without axial displacement. This guarantees the normal oscillation of the swing assembly 400, ensures the stability of the rotating shaft 200's position on the support base 100, prevents axial movement of the rotating shaft 200 during operation, and guarantees the stability and accuracy of the swing assembly 400's oscillation, thereby improving the reliability and efficiency of the entire drug grinding device.
[0026] A counterweight 202 is connected to the other side of the rotating shaft 200, and a handle 203 for easy operation is attached to the counterweight 202. The weight of the counterweight 202 can be adjusted according to the actual situation of the swing assembly 400 to achieve a balanced effect. Simultaneously, the handle 203 allows the operator to control the swing amplitude and frequency of the swing assembly 400 by gripping the handle 203. In other words, on the one hand, the counterweight 202 balances the weight of the swing assembly 400 during swing, making the swing more stable; on the other hand, the handle 203 facilitates manual operation of the swing assembly 400, increasing the flexibility and convenience of the device.
[0027] The grinding assembly 500 includes a grinding jar 501, the top of which abuts against a cover plate 502. A grinding motor 503 is mounted on the top of the cover plate 502. The grinding assembly 500 includes a grinding jar 501, the top of which abuts against the cover plate 502, and the cover plate 502 serves to seal the grinding jar 501. The grinding motor 503 is mounted on the top of the cover plate 502, and can drive the grinding components to grind the drug. The grinding jar 501 is used to contain the drug to be ground, the cover plate 502 can prevent the drug from splashing out during the grinding process, and the grinding motor 503 provides power for the grinding process to ensure the normal progress of drug grinding.
[0028] The output shaft of the grinding motor 503 is connected to a rotating shaft 504 via a coupling. A cutting tool 505 for grinding the medicine is fixedly mounted on the bottom of the rotating shaft 504. The coupling ensures coaxiality between the motor output shaft and the rotating shaft 504, resulting in smoother power transmission. When the grinding motor 503 starts, its output shaft drives the rotating shaft 504 to rotate, which in turn drives the cutting tool 505 to rotate, grinding the medicine in the grinding jar 501. The cutting tool 505 cuts and grinds the medicine, improving the efficiency and quality of the grinding process.
[0029] A scraper 506 is also provided on the rotating shaft 504. The scraper 506 is used to scrape the medicine on the tank wall, and the scraper 506 is located at the top of the cutter 505. When the rotating shaft 504 rotates, the scraper 506 rotates accordingly. The edge of the scraper 506 contacts the tank wall of the grinding tank 501, scraping off the medicine adhering to the tank wall and allowing it to fall back into the grinding area to be ground by the cutter 505 along with other medicines. The scraper 506 can effectively solve the problem of medicine adhering to the tank wall during the grinding process, so that the medicine on the tank wall can be scraped off and participate in the grinding, improving the grinding uniformity and utilization rate of the medicine.
[0030] The connector 300 includes a support plate 402 and a threaded hole 301 at the bottom of the grinding jar 501, as well as a screw 302 that connects the support plate 402 and the grinding jar 501 through the threaded hole 301. By engaging the screw 302 with the threaded hole 301, the grinding jar 501 can be fixed to the support plate 402. Tightening the screw 302 ensures a secure connection, while removing the screw 302 allows the grinding jar 501 to be removed from the support plate 402. This connection method securely mounts the grinding jar 501 to the support plate 402, ensuring the stability of the grinding assembly 500 during oscillation, while also facilitating the disassembly and installation of the grinding jar 501, and making cleaning and maintenance convenient.
[0031] The method of using this utility model is as follows: Open the cover plate 502 of the grinding jar 501, put the medicine to be ground into the grinding jar 501, and then close the cover plate 502 to ensure that the medicine will not overflow during the grinding process. Then turn on the power of the grinding motor 503. After the grinding motor 503 starts, its output shaft drives the rotating shaft 504 to rotate through the coupling. The cutter 505 fixed at the bottom of the rotating shaft 504 rotates accordingly and begins to grind the medicine in the grinding jar 501. At the same time as the rotating shaft 504 rotates, the scraper 506 on the rotating shaft 504 will also rotate accordingly, returning the medicine adhering to the jar wall to the grinding area for grinding. While grinding the medicine, turn the handle 203 to make the swing component 400 swing with the grinding component 500, so that the medicine shakes in the grinding jar 501, allowing it to fully contact the cutter 505 through shaking, making the medicine more evenly distributed in the grinding jar 501 and improving the grinding effect.
