Abstract
Description
Technical Field
[0001] This utility model relates to the field of tablet press technology, specifically to a tablet press powder scraping device. Background Technology
[0002] In modern pharmaceutical manufacturing, rotary tablet presses have become key equipment in tablet production due to their high efficiency and stable production capabilities. The rotary tablet press uses a rotating disc to drive a die to sequentially complete processes such as powder filling, tableting, and tablet ejection. Throughout the production process, ensuring the precise distribution and timely cleaning of powder on the tablet press disc is crucial for guaranteeing tablet quality.
[0003] Residual drug powder on the tableting tray can have numerous adverse effects on tablet quality. Firstly, residual powder may mix with new powder during subsequent tableting processes, causing deviations in the proportion of active ingredient in each tablet, affecting the accuracy of dosage, and ultimately reducing the therapeutic effect. Secondly, long-term adhesion of powder to equipment components makes them susceptible to moisture and deterioration, potentially contaminating subsequently produced tablets, accelerating equipment wear, shortening equipment lifespan, and increasing maintenance costs. More seriously, if powder is not cleaned promptly, it can cause die blockage during tableting, resulting in uneven tableting pressure and quality defects such as cracked or loose tablets, directly impacting product yield and causing economic losses for pharmaceutical companies. Currently, there is no effective device for scraping residual powder off the tableting tray.

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0039] Example:
[0040] like Figures 1 to 7 As shown, this embodiment discloses a tablet press powder scraping device, comprising:
[0041] Scraping assembly 10 is mounted on a rotary tablet press, with one end of the scraping assembly 10 engaging with the pharmaceutical disc of the rotary tablet press.
[0042] A powder suction component 11 is provided on one side of the rotary tablet press. One end of the powder suction component 11 is provided on the scraping component 10 and is used to suction the powder scraped off by the scraping component 10.
[0043] The scraping assembly 10 includes a mounting structure 12 and a scraping plate 13. The mounting structure 12 is mounted on a rotary tablet press. One end of the scraping plate 13 is detachably connected to the mounting structure 12, and the other end is positioned above the tablet press's drug tray. The bottom of the scraping plate 13 is provided with a scraping part 14. One end of the scraping part 14 is fixedly connected to the scraping plate 13, and the other end contacts and slides against the tablet press's drug tray.
[0044] This invention achieves efficient cleaning of pharmaceutical powder through the coordinated operation of the scraping component 10 and the powder suction component 11. The mounting structure 12 stably fixes the scraping plate 13 to the rotary tablet press. The scraping part 14 at the bottom of the scraping plate 13 is in close contact with the surface of the pharmaceutical tray. When the pharmaceutical tray rotates, the scraping part 14 slides with the tray and scrapes away residual powder in real time. Simultaneously, the powder suction component 11 quickly removes the scraped powder, preventing secondary contamination. Furthermore, the detachable scraping plate 13 facilitates replacement and maintenance. This invention solves the problem that current rotary tablet presses cannot effectively scrape away residual powder from the pharmaceutical tray.
[0045] To facilitate the loading and unloading of the scraping component 10, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the mounting structure 12 includes a mounting base 15, a mounting rod 16, a mounting sleeve 17, and a fixing base 18. The mounting base 15 is mounted on the rotary tablet press and is fixedly connected to the rotary tablet press. The mounting rod 16 is fixedly mounted on the mounting base 15. The mounting sleeve 17 is mounted on the mounting rod 16 and is slidably connected to the mounting rod 16. One end of the fixing base 18 is fixedly connected to the mounting sleeve 17. The top of one end of the scraping plate 13 is detachably connected to the fixing base 18 by bolts.
[0046] The mounting sleeve 17 has a fixing tube 19 on one side, one end of which is fixedly connected to the mounting sleeve 17. The fixing tube 19 has a locking bolt 20 inside, one end of which passes through the fixing tube 19 and through the mounting sleeve 17. The end of the locking bolt 20 abuts against the mounting rod 16.
[0047] The mounting rod 16 is provided with a positioning locking groove 21 that cooperates with the locking bolt 20. The end of the locking bolt 20 is inserted into the positioning locking groove 21 and is connected to the positioning locking groove 21.
[0048] The sliding design of the mounting sleeve 17 and the mounting rod 16, combined with the insertion structure of the locking bolt 20 and the positioning locking groove 21, enables quick installation and removal of the mounting structure 12 while ensuring the stability of the scraper plate 13 after installation. This solves the problems of cumbersome disassembly and inaccurate positioning in traditional mounting structures, significantly improving the maintenance and disassembly efficiency of the scraper assembly 10. Simultaneously, the scraper plate 13 is bolted to the fixing seat 18, facilitating the replacement of the scraper plate 13.
[0049] To facilitate the absorption of scraped powder, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the powder absorption assembly 11 includes an absorption structure 22 and at least three absorption heads 23. The at least three absorption heads 23 are fixedly mounted on the scraping plate 13. One end of each of the at least three absorption heads 23 passes through the scraping plate 13 and is configured to cooperate with the side of the scraping part 14 that scrapes the powder. The absorption structure 22 is connected to the at least three absorption heads 23 through an absorption pipe 24. One end of the absorption pipe 24 is detachably connected to the absorption head 23, and the other end is detachably connected to the absorption structure 22.
[0050] Two suction heads 23 are respectively configured to cooperate with both ends of the scraping part 14, and another suction head 23 is configured to cooperate with the pharmaceutical hole on the pharmaceutical tray of the rotary tableting machine.
[0051] At least three suction heads 23 are distributed at the scraping section 14 and the pharmaceutical hole, and are connected to the suction structure 22 through a detachable suction pipe 24 to form a multi-point synchronous powder suction path. The multi-point suction heads 23 cover both ends of the scraping section 14 and the key areas of the pharmaceutical hole, ensuring that the scraped powder and the residual powder in the pharmaceutical hole are sucked away in time. The detachable pipe design facilitates individual replacement and maintenance, improving the comprehensiveness of powder suction and the flexibility of the equipment.
[0052] Two suction heads 23 collect residual powder from the edges of the scraping section 14 at both ends, while the other head is aligned with the pharmaceutical hole to remove residual powder from the hole. This prevents powder from accumulating at the scraping edge or clogging the pharmaceutical hole, reduces the risk of secondary contamination of the powder, and further ensures the quality of tablet forming.
[0053] To facilitate the installation of the suction pipe 24, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the fixed base 18 is provided with a fixed frame 25. One end of the fixed frame 25 is detachably connected to the fixed base 18 by bolts, and the other end of the fixed frame 25 is located above one side of the scraping plate 13. The fixed frame 25 is provided with a clamp 26 that cooperates with the suction pipe 24, and the suction pipe 24 is engaged with the clamp 26.
[0054] The clamp 26 and the fixing bracket 25 facilitate the installation of the suction pipe 24 and improve the stability of the installation of the suction pipe 24.
[0055] To facilitate the separation of powder and air, this embodiment is an improvement on the above embodiment.

The other end of the dust collection hood 28 is provided with at least three pipe interfaces 31 communicating with the dust collection chamber 30. The pipe interfaces 31 are configured to cooperate with the suction pipe 24, and the suction pipe 24 is detachably connected to the pipe interfaces 31. The conical filter head 29 is disposed at the end of the suction body 27 located inside the dust collection chamber 30 and is detachably connected to the suction body 27.
[0056] The dust collection hood 28 collects the airflow for dust collection through multiple pipe interfaces 31, the conical filter head 29 filters the powder at the inlet of the suction body 27, and the dust collection chamber 30 temporarily stores the dust and is easy to disassemble and clean.
[0057] The connection methods between the conical filter head 29 and the suction body 27, as well as the connection methods between the dust collection hood 28 and the suction body 27, both employ existing technologies, including but not limited to threaded connections or snap-fit connections. The conical filter head 29 efficiently intercepts powder, preventing dust from entering the suction body 27 and causing wear. The detachable dust collection hood 28 and filter head design facilitates regular cleaning and recovery of powder, improving equipment cleanliness and resource utilization. The conical filter head 29 can be the type of conical filter head used in existing vacuum cleaners.
[0058] The suction body 27 includes a suction housing 32, a motor housing 33, a drive motor 34, a mounting bracket 35, a connecting shaft 36, and a fan impeller 37. The suction housing 32 has a receiving cavity 38 that extends through one end of the suction housing 32. The other end of the suction housing 32 has an air inlet 39 communicating with the receiving cavity 38. A conical filter head 29 is fitted with the air inlet 39. The motor housing 33 is located at one end of the suction housing 32 and is used to seal the receiving cavity 38. The motor housing 33 is detachably connected to the suction housing 32. The mounting bracket 35 is located within the receiving cavity. The drive motor 34 is located inside the housing 33 and is slidably connected to the housing 38. One end of the mounting bracket 35 is fixedly connected to the motor housing 33. The drive motor 34 is located inside the motor housing 33. The connecting shaft 36 is located inside the mounting bracket 35. One end of the connecting shaft 36 passes through the mounting bracket 35 and is fixedly connected to the output shaft of the drive motor 34. The connecting shaft 36 is rotatably connected to the mounting bracket 35. The fan impeller 37 is fixedly located at the other end of the connecting shaft 36. The suction housing 32 is provided with a grille air outlet 40 that cooperates with the fan impeller 37. The grille air outlet 40 communicates with the housing 38.
[0059] The motor housing 33 includes a housing body 41 and a housing cover 42. The housing body 41 has a fixed cavity 43 inside, which extends through both ends of the housing body 41. One end of the housing body 41 is respectively fitted with the suction housing 32 and the mounting bracket 35. The housing body 41 and the suction housing 32 are detachably connected by bolts. The housing body 41 is fixedly connected to the mounting bracket 35. The housing cover 42 is located at the other end of the housing body 41 and is detachably connected to the housing body 41 by bolts. The drive motor 34 is installed in the fixed cavity 43 and is detachably connected to the housing cover 42 by bolts. The housing cover 42 has several heat dissipation holes 44, which are respectively connected to the fixed cavity 43.
[0060] The drive motor 34 drives the impeller 37 to rotate via the connecting shaft 36. The impeller 37 draws air out of the suction housing 32 through the grille outlet 40, thus achieving a relative negative pressure suction process. The split housing structure reduces the impact of motor heat on the powder, and the high-speed rotation of the impeller 37 generates stable negative pressure to ensure powder suction power. The detachable motor housing 33 and mounting bracket 35 facilitate maintenance of the drive components. The housing body 41 and housing cover 42 are bolted together to form a closed cavity. The drive motor 34 is fixed inside the housing cover 42, and the heat dissipation holes 44 allow for air circulation and heat dissipation inside and outside the cavity. The heat dissipation holes 44 are designed to extend the motor's service life, prevent high temperatures from affecting the stability of equipment operation, and improve the reliability of the drive system.
[0061] As a further preferred option, the rotatable connection between the connecting shaft 36 and the mounting bracket 35 is sealed using a dynamic sealing structure in the prior art.
