Technical Field
[0001] This utility model relates to the field of pharmaceutical processing equipment technology, and in particular to a tablet press for pharmaceutical use. Background Technology
[0002] To facilitate administration and improve drug quality, some powdered drugs are compressed into tablets. After compression, the drug becomes a solid tablet, which is convenient for patients to take orally, and is easier to carry and measure, reducing the risk of accidental ingestion. At the same time, it also ensures the uniformity of drug weight.
[0003] When compressing pharmaceutical powder into tablets, various types of tablet presses are used. For example, Chinese utility model patent CN208006316U discloses a pharmaceutical tablet press that can easily remove tablets after they are formed without damaging them, ensuring the quality of the tablets. This is achieved by using compression springs on the pressing plate to eject the molded medicine, and by installing anti-jump plates at the pressing holes on the worktable to prevent the molded medicine from being... The invention involves a novel method for discharging tablets. First, by starting a motor, the application drives a telescopic rod to press down, causing the tableting plate to fit snugly against the tableting trough. After tableting, the compression spring at the bottom of the trough separates the medication from the trough. However, when the spring rebounds, it only lifts the trough, leaving the formed medication inside, making it difficult to easily remove the tablets. Second, during the tableting process using the tableting trough and tableting plate, manual loading and unloading are required for each tableting step, resulting in low tableting efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1-5 As shown, the present invention provides a pharmaceutical tablet press, including a worktable 1. Multiple first rollers 2 are fixedly installed at the lower end of the worktable 1. A main controller 3 is fixedly installed at the front end of the worktable 1. A motor 4 is fixedly installed at the top inside the worktable 1, and the motor 4 is electrically connected to the main controller 3 via a connecting wire. A protective cover 5 is fixedly installed at the upper end of the worktable 1. A tablet pressing mechanism 6 is arranged on the worktable 1 inside the protective cover 5. The tablet pressing mechanism 6 includes a tablet pressing disc 7, an upper mounting plate 8, and a lower mounting plate 9. 9 are fixedly connected to each other by a rotating shaft 29, and the tableting plate 7, the upper mounting plate 8, and the lower mounting plate 9 are movably mounted on the worktable 1 by the rotating shaft 29. The lower end of the rotating shaft 29 passes through the worktable 1 and extends to the lower end of the worktable 1 and is connected to the output end of the motor 4 for transmission. Multiple upper pressure rods 10 are movably installed in the upper mounting plate 8, and multiple lower push rods 11 are movably installed in the lower mounting plate 9. A hopper 12 is provided at the rear end of the protective cover 5. The hopper 12 is fixedly installed at the rear end of the protective cover 5 by a bracket 13, and the lower end of the hopper 12 extends into the tableting plate 7.
[0023] like Figures 1-3 As shown, a feeding tray 14 is fixedly installed on one side of the inner side of the protective cover 5. A shovel 15 is also fixedly installed on one side of the inner side of the protective cover 5 above the feeding tray 14. One end of the shovel 15 extends between the tablet pressing plate 7 and the lower mounting plate 9. With the help of the feeding tray 14, the formed tablets can be easily fed out. The shovel 15 can also be used to peel the formed medicine off the lower push rod 11.
[0024] like Figures 1-2 , Figure 5 As shown, a bottom ring 16 is fixedly installed on the workbench 1, and a first notch 17 is opened in the bottom ring 16. A top ring 18 is provided inside the protective cover 5, and a second notch 19 is opened in the top ring 18. The top ring 18 is fixedly installed inside the protective cover 5 through multiple mounting seats 20 on the outside. By fixing the bottom ring 16 on the workbench 1 and the top ring 18 inside the protective cover 5, the lower push rod 11 and the upper pressure rod 10 can be controlled to move up and down respectively.
[0025] like Figures 1-2 , Figure 4As shown, the tableting disc 7 has multiple tableting holes 22 at its bottom. A scraper 30 is also installed inside the bottom of the tableting disc 7, with one end of the scraper 30 away from the tableting disc 7 fixedly mounted on the worktable 1. With the help of the fixed scraper 30, the powder in the tableting disc 7 can be pushed into the tableting holes 22 when the tableting disc 7 rotates. The upper mounting plate 8 has multiple first insertion holes 21. A second roller 24 is rotatably mounted on the upper end of the upper pressure rod 10. Two first fixing rings 25 are fixedly mounted on the outer side of the upper pressure rod 10. The upper pressure rod 10 is inserted into the corresponding first insertion hole 21 through the two first fixing rings 25. The upper pressure rod 10 located between the upper end of the upper mounting plate 8 and one of the first fixing rings 25 is... It is also equipped with a compression spring. Multiple second insertion holes 23 are opened in the lower mounting plate 9. A third roller 26 is rotatably installed at the lower end of the lower push rod 11. Two second fixing rings 27 are fixedly installed on the outside of the lower push rod 11. The lower push rod 11 is inserted into the corresponding second insertion hole 23 through the second fixing rings 27. A guide plate 28 is fixedly installed at the upper end of the lower push rod 11. The lower push rod 11 located between the lower end of the lower mounting plate 9 and one of the first fixing rings 25 is also equipped with a compression spring. By inserting multiple upper pressure rods 10 in the upper mounting plate 8 and multiple lower push rods 11 in the lower mounting plate 9, it can cooperate with the bottom ring 16 and the top ring 18 to realize the processing of drug powder tableting in the tableting hole 22.
[0026] It should be noted that this utility model is a pharmaceutical tablet compressor. When compressing pharmaceutical powder, the powder is quantitatively fed into the tablet compressor 7 via the discharge valve at the lower end of the hopper 12. Simultaneously, the motor 4 drives the pulley at the lower end of the rotating shaft 29 to rotate via the pulley at the output end of the motor 4. This causes the rotating shaft 29 to synchronously drive the tablet compressor 7, the upper mounting plate 8, and the lower mounting plate 9 to rotate. When the corresponding upper pressure rod 10 in the upper mounting plate 8 rotates to the position of the second notch 19 in the top ring 18, the compression spring on the outside of the upper pressure rod 10 and the first fixing ring 25 move the upper pressure rod 10 upwards. Thus, the lower end of the upper pressure rod 10 is pulled out from the corresponding tablet compressor hole 22. As the tablet compressor 7 rotates, since one end of the scraper 30 is fixedly mounted on the worktable 1, the rotating tablet compressor 7, in conjunction with the scraper 30, scrapes the powder into the tablet compressor hole 22. Because the upper end of the corresponding lower push rod 11 is inserted in the lower part of the inner 22, the powder will not leak into the lower mounting plate 9. Then, when the upper pressure rod 10 rotates to the position below the top ring 18, the upper pressure rod 10, in conjunction with the upper second roller 24, moves down in the first insertion hole 21 due to the restriction of the top ring 18. Thus, the powder is compressed and formed in the tableting hole 22 by the upper pressure rod 10 and the lower push rod 11. When the lower push rod 11 rotates to the position of the first notch 17 in the bottom ring 16, the lower push rod 11 moves down with the help of the second fixing ring 27 on the outside and the compression spring. Thus, the upper end of the lower push rod 11 disengages from the tableting hole 22 and takes out the tablet. When the lower push rod 11 drives the medicine through the scraper 15, it can peel the medicine into the guide plate 28 and guide the medicine into the bottom ring 16 through the guide plate 28. The subsequent operation can be repeated.
