[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a dry granulator includes a support frame 1, a granulator body 2 placed on top of the support frame 1, a support platform 3 fixed to the top of the front of the granulator body 2, and fixed frames 4 fixed to the left and right sides of the top of the support platform 3. A first weighing sensor 5 is fixed to the surface of the fixed frames 4. A feeding hopper 6 is arranged between the fixed frames 4. A connecting frame 7 is fixed above the left and right sides of the feeding hopper 6. A drive structure 8 is movably connected to the top of the feeding hopper 6. Mounting rods 9 are arranged on the front and rear sides of the inner wall of the feeding hopper 6, and scrapers 10 are fixed to the surface of the mounting rods 9. The scrapers 10 are in contact with the surface of the inner wall of the feeding hopper 6. A solenoid valve 11 is connected to the bottom of the feeding hopper 6. A connecting pipe 12 is connected to the bottom of the solenoid valve 11. A feed pipe 13 is connected to the top of the front of the granulator body 2. A discharge valve 14 is connected to the bottom of the front side of the feeding hopper 6.

[0025] The fixed frame 4 is L-shaped, and the sensing head at the bottom of the first weighing sensor 5 is fixedly connected to the top of the connecting frame 7. When the staff pours the raw materials into the feeding barrel 6, the feeding barrel 6 will fall due to the increased weight, which will cause the connecting frame 7 to pull the sensing head below the first weighing sensor 5, thereby weighing the raw materials inside the feeding barrel 6.

[0026] The drive structure 8 includes a drive motor 81, a gear 82, a gear ring 83, and a moving table 84. The drive motor 81 is fixed above the front side of the feeding hopper 6. The gear 82 is fixed to the top of the output shaft of the drive motor 81. The gear ring 83 is positioned above the feeding hopper 6 and meshes with the gear 82. The moving table 84 is fixed to the front and rear sides of the inner wall of the gear ring 83, and the top of the mounting rod 9 is fixedly connected to the moving table 84. A guide rail 15 is fixed to the top of the feeding hopper 6. Guide wheels 16 are rotatably connected to the four sides of the bottom of the moving table 84. The guide wheel 16 contacts the surface of the guide rail 15 and rolls with the guide rail 15. When the feeding hopper 6 pours the raw materials into the granulator body 2, the operator can turn on the drive motor 81, which causes the output shaft of the drive motor 81 to drive the gear 82 to rotate, which in turn causes the gear ring 83 above the feeding hopper 6 to rotate. The moving table 84 drives the mounting rod 9 to move. The setting of the guide wheel 16 and the guide rail 15 can improve the stability of the gear ring 83 when rotating. The scraper 10 can scrape off the raw materials remaining on the inner wall surface of the feeding hopper 6 to avoid waste.

[0027] The bottom end of the connecting pipe 12 is connected to the top of the feeding pipe 13, and the connecting pipe 12 is a retractable hose. When the raw materials are poured into the feeding barrel 6, the connecting pipe 12 will contract when the feeding barrel 6 falls, so that the first weighing sensors 5 on both sides can accurately detect the raw materials inside the feeding barrel 6.

[0028] A fixing plate 17 is fixed to the front side of the support platform 3. A second weighing sensor 18 is installed on the top of the fixing plate 17. A receiving box 19 is placed above the second weighing sensor 18 and is located below the discharge valve 14. When there is excess medicine raw material inside the feeding barrel 6, the operator can open the discharge valve 14 to discharge the excess medicine raw material inside the feeding barrel 6. The excess medicine raw material falls into the receiving box 19. The weight of the medicine raw material inside the receiving box 19 can be weighed immediately by the second weighing sensor 18, thereby accurately controlling the medicine raw material inside the feeding barrel 6.

[0029] Working principle: When processing pharmaceutical preparations, the operator first pours the raw materials to be processed into the feeding tank 6, increasing the overall weight of the feeding tank 6. As the feeding tank 6 falls, it pulls the sensor head of the first weighing sensor 5. The first weighing sensor 5 detects the amount of raw materials inside the feeding tank 6. If the weight of the raw materials inside the feeding tank 6 is insufficient, the operator needs to add more raw materials. If the weight of the raw materials inside the feeding tank 6 is excessive, the operator opens the discharge valve 14, which then discharges the raw materials. The raw materials of the medicine inside the feeding hopper 6 are discharged. The excess raw materials are weighed through the receiving box 19. The raw materials inside the feeding hopper 6 are then precisely adjusted to the required level for processing. At this time, the operator opens the solenoid valve 11 and the drive motor 81. The raw materials inside the feeding hopper 6 fall into the lower feed pipe 13 and enter the granulator body 2. The scraper 10 inside the feeding hopper 6 scrapes off the raw materials on the inner wall surface of the feeding hopper 6 to prevent the raw materials from remaining inside the feeding hopper 6. After the raw materials are added, the operator can start the granulation operation.
