[0024] This implementation example Figure 1 , Figure 2 , Figure 3 As shown, a tablet granulation and forming apparatus includes a base 1, a motor 2, an ejection mechanism 3, a granulation disc 4, and a pressure mechanism 5. The motor 2 and the ejection mechanism 3 are both disposed in the inner cavity of the base 1. The granulation disc 4 is rotatably mounted on the base 1. The power output end of the motor 2 is connected to the granulation disc 4. Multiple granulation holes 6 on the granulation disc 4 are sequentially divided into a filling area 41, a granulation area 42, and an ejection area 43 along the circumferential direction. The ejection end of the ejection mechanism 3 is adapted to the granulation hole 6 of the ejection area 43. The pressure mechanism 5 is disposed on the base 1, and the extrusion end of the pressure mechanism 5 is adapted to the granulation hole 6 of the granulation area 42.

[0025] First, the powder is distributed on the filling area 41 of the granulation disc 4, filling the granulation holes 6 of the filling area 41. The motor 2 rotates the granulation disc 4 at a certain angle to the position of the pressure mechanism 5. Then, the pressure mechanism 5 intervenes and extrudes the powder in the granulation holes 6 into tablets. Next, the motor 2 rotates the granulation disc 4 at a certain angle to the position of the ejection mechanism 3. The ejection mechanism 3 intervenes and ejects the tablets from the granulation holes 6. During this process, the continuously distributed filling area 41, granulation area 42 and ejection area 43 work simultaneously. The steps of powder distribution, tablet forming and tablet ejection are carried out synchronously, which greatly saves the tablet forming efficiency and increases the tablet output.

[0026] Preferably, the ejection mechanism 3 includes a first cylinder 7, a first horizontal plate 8, and ejection rods 9. The cylinder 7 is installed vertically upward in the inner cavity of the base 1, the first horizontal plate 8 is installed horizontally on the power output end of the first cylinder 7, and multiple ejection rods 9 are installed vertically on the first horizontal plate 8, and the ejection rods 9 are adapted to the granulation holes 6 in the ejection area 43.

[0027] The first cylinder 7, along with the first horizontal plate 8 and the ejector rod 9, rises to eject the tablets from the granulation holes 6 in the ejection zone 43, thus completing the tablet unloading process.

[0028] Preferably, the pressure mechanism 5 includes a cantilever 10, a second cylinder 11, a second horizontal plate 12, and extrusion rods 13. The cantilever 10 is mounted on the base 1, the second cylinder 11 is mounted vertically downward on the cantilever 10, the second horizontal plate 12 is mounted horizontally on the power output end of the second cylinder 11, and multiple extrusion rods 13 are mounted vertically on the second horizontal plate 12, and the extrusion rods 13 are adapted to the granulation holes 6 in the granulation zone 42.

[0029] The second cylinder 11 lowers the second horizontal plate 12 and the extrusion rod 13, and the extrusion rod 13 extrudes the tablets in the granulation holes 6 of the granulation zone 42 into shape.

[0030] Preferably, the base 1 is provided with a feeding pipe 14 adapted to the filling area 41, and the discharge end of the feeding pipe 14 slides against the upper surface of the granulation disc 4.

[0031] The feed tube 14 provides a scraping (powder scraping) function while filling the granulation holes 6 in the filling zone 41.

[0032] Preferably, such as Figure 4 As shown, a scraper 15 adapted to the ejection area 43 is provided on the base 1, and the bottom of the scraper 15 slides against the upper surface of the granulation disc 4.

[0033] After the ejection mechanism 3 ejects the tablets, the granulation disc 4 rotates, and the scraper 15 scrapes off the ejected tablets.

[0034] Preferably, the bottom of the scraper 15 is provided with a relief groove 151 that is adapted to the ejection end of the ejection mechanism 3.

[0035] Sometimes when the ejector rod 9 of the ejector mechanism 3 rises above the upper surface of the granulation hole 6, the clearance groove 151 can avoid collision when the granulation disc 4 rotates, ensuring that the granulation disc 4 rotates smoothly during unloading.

[0036] Preferably, a proximity sensor 16 is provided on the base 1, and a plurality of positioning blocks 17 adapted to the proximity sensor 16 are provided on the outer periphery of the granulation disk 4. The plurality of positioning blocks 17 correspond one-to-one with the filling area 41, the granulation area 42 and the ejection area 43 respectively.

[0037] The proximity sensor 16 can work with the positioning block 17 to ensure that the granulation disc 4 rotates accurately and works smoothly.

[0038] Preferably, a material trough 18 is provided on the base 1.

[0039] The feed trough 18 is used to collect the tablets scraped off by the scraper plate 15.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
