[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] A tablet compression machine, such as Figure 1-7 As shown, the device includes a frame 1, an upper mold 2 slidably connected to the upper part of the frame 1 via a support plate, a middle mold 3 fixedly connected to the middle part of the frame 1, a mold hole 4 on the middle mold 3, and a lower mold 5 movably connected to the lower part of the frame 1. Both the upper mold 2 and the lower mold 5 are matched with the mold hole 4. A push plate 6 is slidably connected to the middle mold 3, and a baffle 7 is fixedly connected to the middle mold 3 and slidably connected to the push plate 6. The baffle 7 is used to guide and limit the push plate 6. A cleaning mechanism is provided on the middle mold 3 to clean the medicine adhering to the upper mold 2. Figure 7As shown, the lower mold 5 includes a rotating handle rotatably connected to the frame 1. A threaded rod is threaded into the rotating handle, and an electric telescopic rod is installed inside the threaded rod. The telescopic end of the electric telescopic rod is slidably connected to the threaded rod, and a top plate is fixedly connected to the end of the electric telescopic rod. The top plate is adapted to the mold hole 4. When the height of the tablet needs to be adjusted, the operator rotates the rotating handle, which drives the threaded rod to rise and fall, thus adjusting the height of the pressed tablet according to actual needs. After the tablet is pressed, the operator controls the electric telescopic rod to extend, pushing the pressed tablet out of the mold hole 4. Then, the push plate 6 pushes the tablet to one side, without affecting the pressing of the next tablet. After the tablet is removed from the mold hole 4, the operator controls the electric telescopic rod to retract and reset, and the electric telescopic rod drives the top plate to reset. Once the top plate is reset, the operator can add the medication into the die hole 4 for tablet compression. During use, the operator first connects the upper die 2 to the external drive device, then adjusts the height of the lower die 5 within the die hole 4 according to the different medications. Next, the operator controls the upper die 2 to move downwards, and the combined action of the upper die 2 and lower die 5 compresses the medication. After compression, the operator controls the upper die 2 to move upwards and reset, and the lower die 5 pushes the compressed tablet out of the die hole 4. Then, the operator controls the push plate 6 to push the tablet to one side, ensuring that the compressed tablet does not affect subsequent compression work. The cleaning mechanism then cleans the medication adhering to the upper die 2, ensuring the surface of the upper die 2 is clean and preventing medication powder from sticking to the punch and affecting the surface smoothness of the tablets.

[0028] The cleaning mechanism includes a clamping rod 9 fixedly connected to the frame 1, and a cleaning ring 8 slidably connected to the end of the clamping rod 9. In use, the cleaning ring 8 can clean and scrape off the drugs adhering to the surface of the upper mold 2 to ensure the cleanliness of the surface of the upper mold 2.

[0029] The cleaning mechanism also includes a drive unit and a scraper 14. The drive unit is located on the top of the middle mold 3, and the scraper 14 is movably connected to the drive unit. The top of the scraper 14 is on the same horizontal line as the bottom of the cleaning ring 8. In use, the drive unit controls the scraper 14 to rotate. Since the top of the scraper 14 is on the same horizontal line as the bottom of the cleaning ring 8, after the upper mold 2 is reset, the bottom of the upper mold 2 is flush with the bottom of the cleaning ring 8. The rotation of the scraper 14 will scrape off the medicine cleaned by the cleaning ring 8 and the medicine at the bottom of the upper mold 2, ensuring the cleanliness of the surface of the upper mold 2, thereby ensuring the smoothness of the tablet surface.

[0030] The drive unit includes an electric push rod 10 fixedly connected to the middle mold 3. The telescopic end of the electric push rod 10 is fixedly connected to the push plate 6. A rack 11 is fixedly connected to the baffle 7. A large gear 12 is rotatably connected to the push plate 6, meshing with the rack 11. A small gear 13 is rotatably connected to the push plate 6, meshing with the large gear 12. A scraper 14 is fixedly connected to the gear shaft of the small gear 13. In use, when it is necessary to push out the tablet, the operator controls the electric push rod 10 to extend. The push rod 10 moves the push plate 6, which in turn drives the large gear 12 to rotate. The small gear 13 and the scraper 14 rotate accordingly. When the scraper 14 contacts the bottom of the upper mold 2 and the cleaning ring 8, the scraper 14 scrapes off the medicine on the upper mold 2 and the cleaning ring 8, ensuring that the surface of the upper mold 2 is clean. When it is necessary to press the tablets, the operator controls the electric push rod 10 to retract. The electric push rod 10 drives the push plate 6 to reset, thus preparing for the downward movement of the upper mold 2 without hindering the movement of the upper mold 2.

[0031] A vacuum cleaner 22 is fixedly connected to the push plate 6, and a vacuum cleaner cover 23 is fixedly connected to the vacuum cleaner 22. When in use, when the scraper 14 scrapes off the medicine, the operator controls the vacuum cleaner 22 to work. During the scraping process, the medicine will fall downwards, and the vacuum cleaner 22 will pick up the fallen medicine through the vacuum cleaner cover 23, which makes it easier to keep the work surface clean and is conducive to the cleanliness and hygiene of the tablets.

[0032] like Figure 5 As shown, a suction chamber 24 is provided inside the push plate 6, and the vacuum cleaner 22 is connected to the suction chamber 24. A valve 25 is provided at the bottom of the push plate 6. In order to facilitate the discharge of the medicine in the suction chamber 24, the bottom of the suction chamber 24 can also be set into a cone shape. When in use, the vacuum cleaner 22 stores the medicine it sucks up in the suction chamber 24, which is conducive to the collection of medicine. When there is a lot of medicine in the suction chamber 24, the operator controls the valve 25 to open, and the medicine in the suction chamber 24 will be discharged from the valve 25.

[0033] Example 2

[0034] like Figure 1-7As shown, based on Embodiment 1, this utility model has been further optimized. The push plate 6 is provided with a conveying mechanism, which is used to convey drugs and prevent drug blockage. The conveying mechanism includes a conveying pipe 16. A conveying hole is opened in the push plate 6. The top of the push plate 6 is fixedly connected to the conveying pipe 16 corresponding to the conveying hole. A material box 15 is fixedly connected to one side of the push plate 6 through a support rod. The material box 15 is connected to the conveying pipe 16. A conveying unit is provided in the material box 15. The conveying unit is used to prevent drugs with high humidity from condensing in the material box 15, thereby affecting the drug feeding. When the push plate 6 pushes out the tablet, the conveying mechanism works and adds a certain amount of drug into the die hole 4 to prepare for tableting. In use, the conveying unit conveys the drug in the material box 15 to the conveying hole of the push plate 6 through the conveying pipe 16, and then enters the die hole 4 to realize the drug delivery.

[0035] The conveying unit includes a tooth 19 fixedly connected to the baffle 7, a rotating rod 20 rotatably connected inside the material box 15, a first gear 17 fixedly connected to the upper end of the rotating rod 20, a second gear 18 rotatably connected to the top of the material box 15, the first gear 17 and the second gear 18 meshing, an auger 21 fixedly connected to the lower part of the rotating rod 20, a discharge port for discharging medicine at the bottom of the material box 15, the auger 21 cooperating with the discharge port, and a feeding port for adding medicine at the top of the material box 15. In use, the movement of the push plate 6 will drive the material box 15, the first gear 17 and the second gear 18 to move. The meshing of the second gear 18 with the tooth 19 can drive the second gear 18 to rotate, thereby driving the first gear 17 to rotate. The rotating rod 20 drives the auger 21 to rotate, thereby conveying the medicine in the material box 15, realizing the orderly conveying of medicine. At the same time, the auger 21 can effectively avoid the blockage of medicine, facilitating better conveying of medicine.

[0036] Working principle: During use, the operator first connects the upper mold 2 to the external drive device, then adjusts the height of the lower mold 5 within the mold hole 4 according to different drugs. Next, the operator controls the upper mold 2 to move downwards to compress the drug into tablets. After compression, the operator controls the upper mold 2 to move upwards to reset, and the lower mold 5 pushes the compressed tablet out of the mold hole 4. Then, the operator controls the push plate 6 to push the tablet to one side, ensuring that the compressed tablet does not affect subsequent compression work. The cleaning mechanism cleans the drug adhering to the upper mold 2, ensuring the surface of the upper mold 2 is clean and preventing drug powder from sticking to the punch and affecting the surface smoothness of the tablets. After the push plate 6 pushes out the tablet, the conveying mechanism works and adds a fixed amount of drug into the mold hole 4 to prepare for tableting. When it is necessary to push out the tablet, the operator controls the electric push rod 10 to extend, and the electric push rod 10 pushes the push plate 6 to move. The movement of the upper mold 2 and cleaning ring 8 causes the large gear 12 to rotate, which in turn causes the small gear 13 and scraper 14 to rotate. When the scraper 14 contacts the bottom of the upper mold 2 and cleaning ring 8, it scrapes off the medicine on the upper mold 2 and cleaning ring 8, ensuring the surface of the upper mold 2 is clean. When it is necessary to compress tablets, the operator controls the electric push rod 10 to retract, which drives the push plate 6 to reset, thus preparing for the downward movement of the upper mold 2 without obstructing its movement. The movement of the push plate 6 will drive the material box 15, the first gear 17 and the second gear 18 to move. The meshing of the second gear 18 with the teeth 19 can drive the second gear 18 to rotate, which in turn drives the first gear 17 to rotate. The rotating rod 20 drives the auger 21 to rotate, thereby conveying the medicine in the material box 15, realizing the orderly delivery of the medicine. At the same time, the auger 21 can effectively avoid the blockage of the medicine, making it easier to achieve better delivery of the medicine.
