[0024] Please refer to Figures 1-5As shown in the figure, a high-efficiency ferrous citrate tablet preparation device includes a frame 11; a cylinder 12 is fixedly connected to the top of the frame 11; a punch 13 is fixedly connected to the output end of the cylinder 12; a disk body 191 is fixedly connected to the top of the frame 11; a tablet pressing seat 14 is fixedly connected to the position corresponding to the punch 13 at the bottom of the disk body 191; a tablet pressing hole is formed in the middle of the tablet pressing seat 14; a lifting groove is formed at the bottom of the tablet pressing seat 14; a pushing seat 18 is slidably connected in the lifting groove; a top seat 19 is arranged at the top of the pushing seat 18; the top of the top seat 19 is inserted into the interior of the tablet pressing hole; a connecting rod 17 is hinged to the bottom of the pushing seat 18; the bottom end of the connecting rod 17 is rotatably connected to a disk seat 16; a motor 15 is fixedly connected to the bottom of the frame 11; a driving shaft is fixedly connected to the output end of the motor 15; the driving shaft is fixedly connected to the disk seat 16; during use, relying on the motor 15 to drive the driving shaft to rotate, the motor 15 is a servo motor 15, the driving shaft will drive the disk seat 16 to rotate, the disk seat 16, the connecting rod 17 and the pushing seat 18 form a crank connecting rod 17 mechanism, so as to drive the top seat 19 at the top to move up and down. After the punch 13 is inserted into the tablet pressing hole, the ferrous citrate tablets are pressed and formed above the top seat 19. Then, when the top seat 19 moves up, it will push out the ferrous citrate tablets, so that it is convenient for the staff to take out the ferrous citrate tablets, saving time and effort and facilitating the preparation and production of ferrous citrate tablets.

[0025] Further, as Figures 1-3 shown, a rotating shaft 21 is rotatably connected to the middle of the disk body 191; a scraper 22 is fixedly connected to the rotating shaft 21; a feeding groove is formed in the disk body 191; the feeding groove is located on the side of the tablet pressing seat 14; during use, by rotating the rotating shaft 21, relying on the rotating shaft 21 to drive the scraper 22 to rotate, so as to push the ferrous citrate tablets to move, making them move above the feeding groove and then fall from the feeding groove. A container can be placed below the feeding groove for collection.

[0026] Further, as Figure 2 shown, a first bevel gear 31 is fixedly connected to the rotating shaft 21; a second bevel gear 32 is fixedly connected to the driving shaft; the first bevel gear 31 and the second bevel gear 32 are meshed with each other; during use, relying on the driving shaft to drive the second bevel gear 32 and the first bevel gear 31 to rotate, and then drive the scraper 22 to automatically rotate to take out the ferrous citrate tablets. Before use, it is necessary to adjust the transmission ratio of the first bevel gear 31 and the second bevel gear 32 so that the action of the scraper 22 pushing the tablets corresponds to the action of the top seat 19 pushing out the ferrous citrate tablets.

[0027] Further, as Figures 4-5As shown, a groove 41 is formed at the top of the pushing seat 18; a spring 42 is fixedly connected to the bottom of the groove 41; a fixing seat 43 is fixedly connected to the bottom of the groove 41; the fixing seat 43 is fixedly connected to the bottom end of the spring 42; during use, the top seat 19 and the pushing seat 18 are separated, and the top seat 19 and the pushing seat 18 are connected by the spring 42. By selecting springs 42 with different elastic forces accordingly, the pressure on the ferrous citrate tablets can be correspondingly adjusted, thereby improving the uniformity of the density after multiple different ferrous citrate tablets are compacted. Moreover, after the top seat 19 ejects the tablets, the pushing seat 18 will compress the spring 42, so that the top seat 19 maintains an ejected state for a certain period of time, facilitating the scraper 22 to scrape off the ferrous citrate tablets.

[0028] Further, as Figures 4-5 shown, a plurality of sliding grooves 52 are formed at the top of the pushing seat 18; a guide rod 51 is slidably connected in the sliding groove 52; a limiting ring 53 is fixedly connected to the bottom end of the guide rod 51; the guide rod 51 is inserted into the sliding groove 52 and is slidably connected thereto; during use, by providing the cooperation of the guide rod 51 and the sliding groove 52, the top seat 19 and the pushing seat 18 can be guided and positioned, improving the stability, and the limiting ring 53 is used to limit the distance between the top seat 19 and the pushing seat 18, facilitating the pushing seat 18 to pull the top seat 19 downward.

[0029] Further, as Figure 1 and 3 shown, a baffle 6 is fixedly connected to the side of the scraper 22; during use, by providing the baffle 6, the ferrous citrate tablets can be restricted, reducing the situation where they are too offset to enter the blanking chute.

[0030] Further, as Figure 1 shown, a blanking slideway 7 is fixedly connected to the bottom of the blanking chute. During use, the ferrous citrate tablets can be conveniently conveyed to a specified container or place through the blanking slideway 7 for convenient use.

[0031] Working principle: During use, the driving shaft is rotated by the motor 15. The motor 15 is a servo motor 15. The driving shaft drives the disk base 16 to rotate. The disk base 16, the connecting rod 17, and the pushing seat 18 form a crank and connecting rod 17 mechanism to drive the top top seat 19 to move up and down. After the punch 13 is inserted into the tablet pressing hole, the ferrous citrate tablets are pressed and formed above the top seat 19. Then, when the top seat 19 moves upward, it ejects the ferrous citrate tablets, which can facilitate the staff to take out the ferrous citrate tablets, saving time and effort and facilitating the preparation and production of ferrous citrate tablets. By rotating the rotating shaft 21, the scraping plate 22 is driven to rotate by the rotating shaft 21, thereby pushing the ferrous citrate tablets to move so that they move above the blanking chute and then fall from the blanking chute. A container can be placed below the blanking chute for collection. The driving shaft drives the second bevel gear 32 and the first bevel gear 31 to rotate, and then drives the scraping plate 22 to automatically rotate to take out the ferrous citrate tablets. Before use, it is necessary to adjust the transmission ratio of the first bevel gear 31 and the second bevel gear 32 so that the action of the scraping plate 22 pushing the tablets corresponds to the ejection of the ferrous citrate tablets by the top seat 19. The top seat 19 and the pushing seat 18 are separately arranged and are connected by a spring 42. By selecting springs 42 with different elastic forces accordingly, the pressure on the ferrous citrate tablets can be correspondingly adjusted, thereby improving the density uniformity of multiple different ferrous citrate tablets after being pressed. And after the top seat 19 ejects the tablets, the pushing seat 18 will squeeze the spring 42, so that the top seat 19 maintains an ejected state for a certain period of time, facilitating the scraping plate 22 to scrape the ferrous citrate tablets. By setting the guide rod 51 and the sliding groove 52 to cooperate, the top seat 19 and the pushing seat 18 can be guided and positioned, improving stability. And the limiting ring 53 is used to limit the distance between the top seat 19 and the pushing seat 18, facilitating the pushing seat 18 to pull the top seat 19 to move downward. By setting the baffle 6, the ferrous citrate tablets can be restricted to reduce the situation where they deviate too much and cannot enter the blanking chute.
