Detailed Embodiments

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a tablet grinding inspection device, which is mainly used to solve the problem in the prior art that due to the different sizes of tablet particles, direct grinding may lead to incomplete tablet crushing. Large tablet particles may get stuck during the crushing process, causing equipment damage and safety hazards, affecting the uniformity and stability of the medicine, and provides the following technical solutions. Figure 1-Figure 3 Make a detailed description:

[0023] A tablet grinding inspection device, comprising:

[0024] A base 1, a mounting plate 4 is fixedly arranged on one side of the top of the base 1, and an L-shaped plate 5 is connected between the other side of the base 1 and the upper side of the mounting plate 4;

[0025] The grinding assembly 2 is used for grinding the tablets. The grinding assembly 2 includes a fixed plate 201 fixedly arranged between the mounting plate 4 and the middle part of the L-shaped plate 5. A mounting column 202 is fixedly embedded in the middle part of the fixing plate 201. A grinding groove 2021 is configured in the middle of the top of the mounting column 202. An abrasive tube 205 is fixedly arranged in the middle of the bottom of the mounting column 202. The abrasive tube 205 is connected to the grinding groove 2021. A grinding column 203 is arranged directly above the mounting column 202. The bottom end of the grinding column 203 is connected to a slide bar 204. The slide bar 204 slides and penetrates inside the abrasive tube 205. The surface of the slide bar 204 is evenly distributed with abrasive grooves 2041.

[0026] The rotating lifting mechanism 3 is arranged on the upper side of the L-shaped plate 5. The rotating lifting mechanism 3 is used to drive the crushing column 203 to rotate and lift. The rotating lifting mechanism 3 includes a rotating rod 301 rotatably connected to the middle of the top of the L-shaped plate 5. A mounting cylinder 302 is fixedly provided at the bottom of the rotating rod 301. The crushing column 203 slides and is inserted into the interior of the mounting cylinder 302. The surface of the mounting cylinder 302 is constructed with a spiral channel 303. The surface of the crushing column 203 is fixedly provided with an extension rod 2031. The extension rod 2031 slides and is inserted into the interior of the spiral channel 303. A driving member is arranged on the upper side of the mounting plate 4. The driving member is used to drive the rotating rod 301 to perform a rotational motion.

[0027] Workflow Description:

[0028] Preparation: Put the tablets to be tested into the grinding tank 2021 (it should be noted that the slide bar 204 is always inserted into the abrasive tube 205 and will not be separated from the abrasive tube 205 even at the highest position, so the intact tablets will not enter the abrasive tube 205);

[0029] Starting device: Turn on the drive motor 308. Through the drive disk 309 and the connecting rod 307, drive the rotating rod 301 to rotate. As the rotating rod 301 rotates, the crushing column 203 inside the mounting cylinder 302 starts to rotate and move up and down. The crushing column 203 enters and exits the crushing groove 2021 to initially crush the tablets, turning them into smaller particles.

[0030] Further grinding: The tablet particles after initial crushing enter the abrasive tube 205. The sliding rod 204 slides inside the abrasive tube 205, and the inclined groove on its surface further grinds the tablet particles.

[0031] Collecting powder: The fully ground medicine powder finally falls from the lower port of the abrasive tube 205 for subsequent inspection.

[0032] This tablet powder grinding and inspection device mainly uses the rotating and lifting mechanism 3 to drive the crushing column 203 to rotate and move up and down, realizing the crushing and grinding of tablets. The effective treatment in the initial crushing stage reduces the possibility of large - particle tablets directly entering the abrasive tube 205, reduces the risk of material jamming, and avoids the problem of incomplete crushing caused by uneven particle sizes in traditional methods.

[0033] As Figure 2 shown, in some embodiments, the driving member includes a U - shaped plate 304 fixed to the top of the rotating rod 301. A guiding rod 305 is fixed between the inner side walls of the U - shaped plate 304. A connecting ring 306 is slidably sleeved on the surface of the guiding rod 305. A connecting rod 307 is fixed to the surface of the connecting ring 306. The outer wall of the mounting plate 4 is equipped with a drive motor 308. The output shaft of the drive motor 308 is connected to a drive disk 309. One end of the connecting rod 307 away from the connecting ring 306 slidably penetrates through the side of the drive disk 309. More specifically, for the working principle of the driving member, after the drive motor 308 is started, its output shaft drives the drive disk 309 to rotate. The rotation of the drive disk 309 is transmitted to the connecting ring 306 through the connecting rod 307. The connecting ring 306 slides on the surface of the guiding rod 305, driving the U - shaped plate 304 to swing reciprocally, and further causing the rotating rod 301 at the bottom of the U - shaped plate 304 to perform a rotary motion. The rotation of the rotating rod 301 further drives the crushing column 203 to rotate and move up and down through the spiral channel 303.

[0034] As Figure 2 shown, in some embodiments, the bottom end of the crushing column 203 is conical, and the crushing groove 2021 matches the bottom end of the crushing column 203. More specifically, the conical design at the bottom end of the crushing column 203 helps to concentrate the pressure, enabling the tablets to be more effectively broken in the initial crushing stage. This design can better adapt to tablets of different sizes and hardnesses, ensuring that each tablet can be fully processed. The conical bottom end not only helps to break the tablets but also plays a guiding role, enabling the broken tablet particles to smoothly enter the abrasive tube 205.

[0035] like Figure 3 As shown, in some embodiments, the abrasive groove 2041 is an oblique groove, and the opening is tilted downward. More specifically, the surface structure of the oblique groove increases the contact area with the tablet particles, thereby improving the grinding efficiency. This design ensures that each tablet particle can be fully ground. The opening of the oblique groove is tilted downward, which helps the tablet particles to flow smoothly during the grinding process and reduces the risk of material jamming. This design allows the tablet particles to slide naturally under the action of gravity to avoid clogging.

[0036] like Figure 2 As shown, in some embodiments, a tube cover 2051 is threadedly connected to the lower end of the abrasive tube 205. More specifically, the tube cover 2051 is threadedly connected to the lower end of the abrasive tube 205, thereby ensuring the sealing of the inside of the abrasive tube 205, thereby preventing leakage of powder during the grinding process and keeping the working environment clean.

[0037] like Figure 2 As shown, in some embodiments, a beaker groove 101 is provided in the middle of the top of the base 1. The beaker groove 101 is an annular ladder groove, and is concentrically arranged with the abrasive tube 205. More specifically, the design of the annular ladder groove enables the beaker groove 101 to adapt to beakers of different diameters. At the same time, the structure of the annular ladder groove helps to stabilize the beaker placed therein, reducing the possibility of shaking or shifting of the beaker during the grinding process. The concentric arrangement of the beaker groove 101 and the abrasive tube 205 ensures that the tablet powder can accurately fall into the beaker after grinding, avoiding powder scattering or contamination of the working environment.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
