[0031] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0032] like Figures 1 to 5 As shown, a pharmaceutical tablet compressor includes a base 1, a rotating shaft 11 rotatably mounted on the base 1, a support plate 12 coaxially mounted on the top of the rotating shaft 11, a mold plate 13 coaxially mounted on the rotating shaft 11, a plurality of pressing holes 131 evenly distributed along its circumference on the mold plate 13, a plurality of mounting holes 121 evenly distributed along its circumference on the support plate 12, the plurality of mounting holes 121 corresponding one-to-one with the plurality of pressing holes 131, a pressing block 122 slidably mounted in the mounting hole 121, a frame 14 mounted on the base 1, a pressing assembly 2 for driving the pressing block 122 to move mounted on the frame 14, a feeding assembly 3 mounted on the bottom of the frame 14, a feeding assembly 4 and a discharging assembly 5 mounted on one side of the base 1, and a drive assembly 6 mounted on the bottom of the base 1; During operation, the drive component 6 drives the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, the support plate 12 and the mold plate 13 will rotate synchronously. When the mold plate 13 rotates to the position of the feeding component 4, the feeding component 4 adds the powder into the pressing hole 131. Then the mold plate 13 will continue to rotate. When the mold plate 13 moves to the position of the pressing component 2, the pressing component 2 will drive the pressing rod 23 and the pressing block 122 to press the powder in the pressing hole 131. When the mold plate 13 rotates to the top component 3, the top component 3 lifts the tablet from the mold plate 13. Then the unloading component 5 removes the tablet from the mold plate 13, thus completing the production of the tablet. The production structure is simple and convenient, can be continuously produced, has low labor intensity, and high efficiency.

[0033] like Figures 1 to 5As shown, the pressing assembly 2 includes a pressing ring 21, which is fixedly mounted on the frame 14 and coaxially arranged with the rotating shaft 11. A power protrusion 22 is coaxially fixedly mounted on the pressing ring 21, and the power protrusion 22 is connected to the pressing ring 21 by an arc. A pressing rod 23 is mounted on the top of the pressing block 122, and the pressing rod 23 slides through the support plate 12. A first return spring 24 is sleeved on the pressing rod 23, and the other end of the first return spring 24 is connected to the inner wall of the mounting hole 121. A first roller 25 is rotatably mounted on the top of the pressing rod 23, and the first roller 25 is rolled on the pressing ring 21. In use, the rotating shaft 11 is driven to rotate by the driving assembly 6. During the rotation of the rotating shaft 11, the support plate 12 is driven to rotate. The support plate 12 rotates synchronously, which drives the pressing rod 23 to rotate synchronously. During the rotation of the pressing rod 23, the first roller 25 at the bottom of the pressing rod 23 will move along the pressing ring 21. When the first roller 25 passes the power protrusion 22, the pressing rod 23 will move in the vertical direction, thereby driving the pressing block 122 to extend out of the support plate 12 and move towards the pressing hole 131 on the mold plate 13, thereby pressing the powder in the pressing hole 131. As the support plate 12 continues to rotate, the pressing rod 23 will gradually move away from the power protrusion 22. Under the action of the first return spring 24, the pressing rod 23 and the pressing block 122 will move away from the pressing hole 131 and be stored in the mounting hole 121.

[0034] like Figures 1 to 5 As shown, the ejector assembly 3 includes an ejector block 31, which is slidably installed in the pressing hole 131. An ejector rod 32 is coaxially mounted on the bottom of the ejector block 31, passing through the bottom of the mold plate 13. A second roller 33 is rotatably mounted on the bottom of the ejector rod 32. An ejector ring 34 is fixedly mounted on the bottom of the frame 14, and the ejector ring 34 is coaxially arranged with the rotating shaft 11. A drive protrusion 35 is coaxially mounted on the ejector ring 34. The installation height of the top of the drive protrusion 35 is higher than the installation height of the ejector ring 34, and the bottom of the drive protrusion 35 is arc-connected with the ejector ring 34. The second roller 33 is rotatably mounted on the ejector ring 34 and the drive protrusion 35. A second reset rod is sleeved on the ejector rod 32. Spring 36, one end of the second return spring 36 is connected to the bottom of the ejector rod 32, and the other end is connected to the bottom of the mold plate 13; in use, after the powder is squeezed by the pressing component 2 and the pressing block 122, the drive component 6 drives the rotating shaft 11 to continue to rotate. During the rotation of the rotating shaft 11, the mold plate 13 will rotate synchronously. During the rotation of the mold plate 13, the ejector rod 32 will rotate synchronously. The second roller 33 will move along the ejector ring 34, and then the second roller 33 will move along the drive protrusion 35. During the movement, the ejector rod 32 will move in the vertical direction, thereby lifting the tablet located in the pressing hole 131 to the top of the mold plate 13, so that the subsequent feeding component 5 can remove the tablet from the top of the mold plate 13.

[0035] like Figures 1 to 5 As shown, the feeding assembly 4 includes a mounting frame 41, on which a feeding cylinder 42 is mounted. A feeding pipe 43 is connected to the bottom of the feeding cylinder 42, and a feeding box 44 is connected to the other end of the feeding pipe 43. The feeding box 44 is located between the mold plate 13 and the support plate 12. The bottom opening of the feeding box 44 is configured to communicate with the pressing hole 131, and the bottom of the feeding box 44 is slidably connected to the mold plate 13. A flexible scraper 45 is installed at the bottom of the feeding box 44. In use, the powder is added into the feeding cylinder 42. Under the action of gravity, the powder will move along the feeding pipe 43 into the feeding box 44, and then fall from the feeding box 44 into the pressing hole 131 on the mold plate 13 at the bottom of the feeding box 44, so as to facilitate the subsequent pressing of the powder by the pressing block 122. The flexible scraper 45 can scrape off the excess powder at the top of the pressing hole 131.

[0036] like Figures 1 to 5 As shown, the feeding assembly 5 includes a feeding shaft 51, which is rotatably mounted on the machine base 1. Multiple feeding scrapers 52 are coaxially mounted on the feeding shaft 51, and the number of feeding scrapers 52 is the same as the number of pressing holes 131. A feeding plate 53 is obliquely mounted on the machine base 1, and an arc-shaped baffle strip 54 is mounted on the top of the feeding plate 53. In use, the feeding shaft 51 is driven to rotate synchronously by the driving assembly 6. During the rotation of the feeding shaft 51, the feeding scrapers 52 will rotate synchronously. During the rotation of the feeding scrapers 52, the tablets lifted by the ejector assembly 3 to the top of the mold plate 13 will be pushed, so that the tablets move towards the feeding plate 53, so as to separate the tablets from the mold plate 13.

[0037] like Figures 1 to 5 As shown, the feeding plate 53 has multiple sieve holes 55 evenly distributed on it, and a recycling plate 56 is installed at an incline on the bottom of the feeding plate 53. During use, when the drive assembly 6 drives the feeding shaft 51 to rotate, the pressed tablets are pushed onto the feeding plate 53. The tablets then slide along the feeding plate 53. During the sliding process, excess powder on the tablets falls onto the recycling plate 56 through the sieve holes 55, so as to facilitate the recycling of excess powder and obtain relatively clean tablets.

[0038] like Figures 1 to 5As shown, the drive assembly 6 includes a drive motor 61, a power shaft 62 coaxially mounted on the output shaft of the drive motor 61, a first driving bevel gear 63 and a second driving bevel gear 64 coaxially fixed on the power shaft 62, a first driven bevel gear 65 coaxially mounted on the bottom of the rotating shaft 11, and a second driven bevel gear 66 coaxially mounted on the bottom of the unloading shaft 51. The first driving bevel gear 63 meshes with the first driven bevel gear 65, and the second driving bevel gear 64 meshes with the second driven bevel gear 66. In use, the drive motor 61 is started, and the drive motor... During the rotation of 61, the power shaft 62 will rotate synchronously. During the rotation of the power shaft 62, the first driving bevel gear 63 and the second driving bevel gear 64 will rotate synchronously. During the rotation of the first driving bevel gear 63, the first driven bevel gear 65 will rotate synchronously. During the rotation of the first driven bevel gear 65, the rotating shaft 11 will rotate synchronously. During the rotation of the second driving bevel gear 64, the second driven bevel gear 66 will rotate synchronously. During the rotation of the second driven bevel gear 66, the unloading shaft 51 will rotate synchronously.

[0039] like Figures 1 to 5 As shown, a stirring rod 46 is rotatably installed inside the feeding box 44, and a power motor 47 is installed on the mounting frame 41. The power motor 47 is coaxially connected to the stirring rod 46. When in use, the power motor 47 is started. During the rotation of the power motor 47, the stirring rod 46 will rotate synchronously. During the rotation of the stirring rod 46, the powder in the feeding box 44 will be dispersed, so that the powder in the feeding box 44 can fall into the pressing hole 131, thus avoiding the blockage of the powder in the feeding box 44 to a certain extent.

[0040] The implementation principle of this embodiment is as follows: the drive component 6 drives the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, the support plate 12 and the mold plate 13 will rotate synchronously. When the mold plate 13 rotates to the position of the feeding component 4, the feeding component 4 adds the powder into the pressing hole 131. Then the mold plate 13 will continue to rotate. When the mold plate 13 moves to the position of the pressing component 2, the pressing component 2 will drive the pressing rod 23 and the pressing block 122 to press the powder in the pressing hole 131. When the mold plate 13 rotates to the top component 3, the top component 3 lifts the tablet from the mold plate 13. Then the unloading component 5 removes the tablet from the mold plate 13, thereby completing the production of the tablet.

[0041] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
