Description

Technical Field

[0001] This utility model relates to the field of dry suspension production technology, and more specifically, to a dry suspension grinding device. Background Technology

[0002] Dry suspensions are pharmaceutical preparations made by preparing poorly soluble drugs into powders or granules with suitable excipients. When used, they are dispersed into a suspension by adding water and shaking. This form of preparation is convenient to carry, has good stability, and is easy to take, making it especially suitable for patients with swallowing difficulties, such as children and the elderly.

[0003] However, existing dry suspensions often suffer from incomplete grinding during the grinding process, resulting in the presence of particles within the powder. This prevents the dry suspension from dissolving properly during use, rendering it unusable and prone to clogging the discharge port during collection and packaging. Therefore, a dry suspension grinding device has been developed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dry suspension grinding device. The technical problem to be solved by the present invention is that when existing dry suspensions are ground, the grinding is incomplete and particles are mixed in the powder. As a result, the particles cannot be dissolved when the dry suspension is used, causing the dry suspension to be unusable. It also easily causes blockage of the discharge port when collecting and dispensing the dry suspension.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dry suspension grinding device, comprising a shell assembly, wherein a sieving and grinding assembly is disposed in the inner cavity of the shell assembly, and a grinding assembly is disposed on the top of the shell assembly;

[0006] The screening and grinding assembly includes an inclined block, a base column fixedly connected to the top center of the inclined block, a first motor fixedly connected to the top of the base column, a rotating rod fixedly connected to the top of the first motor, a locking column fixedly connected to the top of the rotating rod, multiple T-shaped locking grooves on the surface of the locking column, a protective cover fixedly connected to the top of the base column, a screen plate sleeved on the outer surface of the rotating rod, a through hole at the intersection of the screen plate and the rotating rod, a locking ring sleeved on the surface of the locking column, multiple T-shaped locking blocks fixedly connected to the inner side of the locking ring, multiple scrapers fixedly connected to the outer surface of the locking ring, multiple center columns fixedly connected to the outer surface of the locking ring, grinding rollers sleeved on the outer surface of each center column, and a conical locking cover rotatably connected to the top of the locking column.

[0007] In a preferred embodiment, the grinding assembly includes a grinding box with multiple through holes extending through its outer surface. Multiple baffles are fixedly connected to the top of the inner wall of the grinding box. Rotating columns are provided through the inner walls of the through holes. Grinding rollers are sleeved on the outer surfaces of the rotating columns. A gear is fixedly connected to one end of each rotating column. A second motor is fixedly connected to the side of each gear away from the rotating column. A placement frame is fixedly connected to the bottom of the second motor.

[0008] In a preferred embodiment, the housing assembly includes a base frame, a discharge box is fixedly connected to the top of the base frame, a re-grinding box is fixedly connected to the top of the discharge box, an installation groove is provided at the bottom of the re-grinding box, and a door is provided on one side of the discharge box.

[0009] In a preferred embodiment, the T-shaped locking groove intersects with the T-shaped locking block, the top of the perforation and the scraper intersect with the bottom of the grinding roller, and the plurality of scrapers and the central column are symmetrically arranged on the surface of the locking ring.

[0010] In a preferred embodiment, the bottom of the grinding roller inside the grinding box is also provided with an inclined discharge groove, and the multiple gears are in a meshing state.

[0011] In a preferred embodiment, the screen plate is fixedly connected in the mounting groove, the inclined block is fixedly connected to the bottom of the discharge box cavity, and the grinding box is fixedly connected to the top of the re-grinding box.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by providing a shell assembly and a grinding assembly, allows for direct pouring of the dry suspension into the grinding chamber during later use. The second motor is then started, and the two grinding rollers rotate relative to each other to perform the first grinding of the dry suspension. Fine powder will pass directly through the sieve disc into the discharge box. The ground dry suspension can then be easily removed by simply opening the chamber door. If the sieve disc becomes clogged after prolonged use, the discharge box and re-grinding box can be disassembled, the sieve disc removed for cleaning, and then reinstalled in the mounting slot for continued use. This solves the problem of easy clogging of the discharge port during the collection and dispensing of dry suspension.

[0014] 2. This utility model, by incorporating a sieving and grinding assembly, addresses the issue of incomplete grinding of the dry suspension by the two grinding rollers. When the dry suspension falls to the top of the sieve tray and cannot fall into the grinding chamber, the first motor drives the rotating rod, causing the locking ring to rotate the two scrapers and the central column. During this rotation, the grinding rollers perform a secondary grinding of the remaining dry suspension on the top of the sieve tray. The scrapers then push the dry suspension on the top of the sieve tray, allowing it to flow and increasing the probability of it falling. This solves the problem of incomplete grinding and the presence of particles within the powder during the grinding of existing dry suspensions, which prevents the dry suspension from dissolving during use and renders it unusable.

[0024] The grinding assembly 3 includes a grinding box 31. Multiple through holes 32 are provided on the outer surface of the grinding box 31. Multiple baffles 33 are fixedly connected to the top of the inner wall of the grinding box 31. Rotating columns 34 are provided through the inner walls of the through holes 32. Grinding rollers 35 are sleeved on the outer surface of the rotating columns 34. A gear 36 is fixedly connected to one end of the rotating columns 34. A second motor 37 is fixedly connected to the side of a single gear 36 away from the rotating column 34. A placement rack 38 is fixedly connected to the bottom of the second motor 37.

[0025] The outer casing assembly 1 includes a base frame 11, a discharge box 12 is fixedly connected to the top of the base frame 11, a re-grinding box 13 is fixedly connected to the top of the discharge box 12, an installation groove 14 is provided at the bottom of the re-grinding box 13, and a box door 15 is provided on one side of the discharge box 12.

[0026] Among them, the T-shaped locking groove 26 intersects with the T-shaped locking block 211, the top of the perforation 29 and the scraper 212 intersect with the bottom of the grinding roller 214, and multiple scrapers 212 and the central column 213 are symmetrically arranged on the surface of the locking ring 210; in later use, the dry suspension can be directly ground by the scraper 212 and the grinding roller 214.

[0027] The grinding roller 35 inside the grinding box 31 also has an inclined discharge groove at the bottom, and multiple gears 36 are meshed with each other, so that the grinding rollers 35 can rotate in opposite directions to achieve the effect of the first grinding.

[0028] The screen plate 28 is fixedly connected in the mounting groove 14, the inclined block 21 is fixedly connected in the bottom of the inner cavity of the discharge box 12, and the grinding box 31 is fixedly connected in the top of the re-grinding box 13. The screen plate 28 in the mounting groove 14 can be disassembled during later use. After prolonged use, the screen plate 28 can be directly removed for cleaning to avoid clogging problems after long-term use.

[0029] Working principle of this utility model:

[0030] In later use, the dry suspension can be directly poured into the grinding box 31, and the second motor 37 is started. The two grinding rollers 35 rotate relative to each other to perform the first grinding of the dry suspension. The fine powder will directly pass through the sieve plate 28 into the discharge box 12. Later, the ground dry suspension can be taken out by simply opening the box door 15. After prolonged use, the sieve holes in the sieve plate 28 may become clogged. In later use, if the dry suspension that has not been fully ground by the two grinding rollers 35 falls to the top of the sieve plate 28 and cannot fall into the grinding box 31, the first motor 23 drives the rotating rod 24, which causes the locking ring 210 to drive the two scrapers 212 and the central column 213 to rotate. During the process, the grinding roller 214 performs a second grinding on the dry suspension that has not been ground completely on the top of the sieve plate 28. Then, the scraper 212 pushes the dry suspension on the top of the sieve plate 28 to make it flow, increasing the probability of it falling off. This solves the problem that existing dry suspensions are not ground thoroughly during grinding, and the powder contains particles, which prevents the particles from dissolving when the dry suspension is used, making it unusable. Alternatively, the discharge box 12 and the re-grinding box 13 can be disassembled, the sieve plate 28 can be taken out for cleaning, and then it can be installed in the installation slot 14 for continued use. This also solves the problem of easy blockage of the discharge port when collecting and dispensing dry suspensions.
