Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical granulation technology, and in particular to a granulation device for pharmaceutical production. Background Technology

[0002] When pharmaceutical factories produce solid granular drugs, they usually need to store the fixed granular drugs in designated loading silos. This requires a granulation feeding device to place the granules onto a vibrating plate. The vibrating plate is driven by a vibrator to vibrate, and the vibrating plate moves the granules. During the granulation process, granules that do not meet the size requirements need to be filtered, which requires a filter plate. However, when filtering drugs of different sizes, the fixed pore size on the filter plate makes it impossible to adapt to granules of different sizes.

[0003] Common granulation devices used in pharmaceutical production only include granulation and filtration functions. They can transport granules and filter out granules that are not up to size. However, they lack the function of adjusting the filter pore size, which cannot guarantee that the pore size can be adjusted according to different granule sizes. This can easily lead to problems where the pore size on the filter plate cannot be adapted to different granule sizes, affecting the filtration effect.

[0004] Therefore, to address the lack of filter hole adjustment function in the aforementioned granulation device for pharmaceutical production, a granulation device for pharmaceutical production can be designed. This device uses a drive motor to drive a drive gear to rotate. The drive gear, through meshing with meshing teeth, causes a rack to move backward. The rack, via a connecting rod, causes a movable plate to move backward until the filter hole on the movable plate, which is compatible with the size of the granules, is located below the three feeding partitions. This movement then stops, thus achieving the function of filter hole adjustment. Utility Model Content

[0005] To overcome the problem that common granulation devices used in pharmaceutical production lack the function of adjusting the filter pore size, which cannot guarantee that the filter pore size can be adjusted according to different sizes of granules, it is easy for the pore size on the filter plate to be unable to match different sizes of granules, thus affecting the filtration effect.

[0006] The technical solution of this utility model is as follows: a granulation device for pharmaceutical production, including a support base; it also includes a movable plate, filter holes, a connecting rod, a toothed rod, meshing teeth, a concave frame, a drive motor, and a drive gear. The top of the support base is provided with a movable plate, and the top of the movable plate is provided with several filter holes of different diameters at equal intervals. The middle of the front side of the movable plate is provided with a connecting rod, and the bottom of the rear side of the connecting rod is provided with a toothed rod. The top of the toothed rod is provided with several meshing teeth at equal intervals. The bottom of the support base is provided with a concave frame corresponding to the position of the toothed rod. The middle of the right side of the concave frame is provided with a drive motor, and the output end of the drive motor on the left side is connected to the drive gear through the concave frame.

[0007] Preferably, a drive motor drives a drive gear to rotate. The drive gear, through meshing with meshing teeth, drives a rack to move backward. The rack, via a connecting rod, drives a movable plate to move backward until the filter holes on the movable plate, which are adapted to the size of the drug particles, are located below the three feeding partitions. This achieves the function of adjusting the filter holes, thus solving the problem of common pharmaceutical granulation devices that only include granulation and filtration functions. These devices can transport drug particles and filter out those that are not up to size, but lack the function of adjusting the filter holes. This makes it impossible to ensure that the filter hole diameter can be adjusted according to different sizes of drug particles, which can easily lead to the problem that the hole diameter on the filter plate cannot be adapted to different sizes of drug particles, affecting the filtration effect.

[0008] Preferably, the rear end of the rack is inserted into the inner side of the concave frame, and the drive gear meshes with the meshing teeth.

[0009] Preferably, a left side plate is provided on the left side of the top of the support base, a right side plate is provided on the right side of the top of the support base, and three feeding partitions are provided at equal intervals on the top of the left side plate.

[0010] Preferably, two baffles are symmetrically arranged on the left side of the top of the left side plate, corresponding to the position of the feeding baffle, and three discharge baffles are equally spaced on the top of the right side plate.

[0011] Preferably, the feeding baffle and the discharging baffle are welded together as one piece, and a counterweight is provided on the left side of the support base.

[0012] Preferably, a support frame is provided on the left side of the top of the right side plate, and two vibration motors are symmetrically arranged on the top of the support frame.

[0013] Preferably, four leg connectors are symmetrically arranged at the left and right ends of the front and rear sides of the support base. A spring is fitted at the bottom of the leg connector, and a support leg is fitted at the bottom of the spring.

[0014] The beneficial effects of this utility model are:

[0015] 1. The drive motor drives the drive gear to rotate. The drive gear, through meshing with the meshing teeth, drives the rack to move backward. The rack, through the connecting rod, drives the movable plate to move backward until the filter holes on the movable plate, which are adapted to the size of the medicine particles, are located below the three feeding partitions. This achieves the function of filter hole adjustment. This solves the problem of common medicine production granulation devices that only include granulation and filtration functions. They can transport medicine particles and filter out those that are not up to size, but lack the function of filter hole adjustment. They cannot guarantee that the filter hole diameter can be adjusted according to different sizes of medicine particles. This can easily lead to the problem that the hole diameter on the filter plate cannot be adapted to different sizes of medicine particles, affecting the filtration effect.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a granulation device for pharmaceutical production, including a support base 1; it also includes a movable plate 2, filter holes 3, a connecting rod 4, a rack 5, meshing teeth 6, a concave frame 7, a drive motor 8, and a drive gear 9. The movable plate 2 is located on the top of the support base 1. Several filter holes 3 of varying diameters are evenly spaced through the top of the movable plate 2. A connecting rod 4 is located in the middle of the front side of the movable plate 2. A rack 5 is located at the bottom rear side of the connecting rod 4. Several meshing teeth 6 are evenly spaced through the top of the rack 5. A concave frame 7 is located at the bottom of the support base 1 corresponding to the rack 5. A drive motor 8 is located in the middle of the right side of the concave frame 7. The output end of the drive motor 8 on the left side passes through the concave frame 7 and is connected to the drive gear 9. The drive motor 8 drives the drive gear 9 to rotate. The drive gear 9, through meshing with the meshing gear 6, drives the rack 5 to move backward. The rack 5, through the connecting rod 4, drives the movable plate 2 to move backward until the filter hole 3 on the movable plate 2, which is adapted to the size of the medicine granules, is located below the three feeding partitions 12. The movement stops then, realizing the function of adjusting the filter hole 3. This solves the problem of common medicine granulation devices, which only include the functions of granulation and filtration. They can transport medicine granules and filter those that are not up to size, but lack the function of adjusting the filter hole 3. This makes it impossible to ensure that the diameter of the filter hole 3 can be adjusted according to the different sizes of medicine granules. It is easy for the hole diameter on the filter plate to be unable to adapt to the different sizes of medicine granules, which affects the filtration effect.

[0023] Please see Figures 2-4 In this embodiment, the feeding baffle 12 and the discharging baffle 14 are welded together. A counterweight 15 is provided on the left side of the support base 1, and a support frame 16 is provided on the left side of the top of the right side plate 11. Two vibration motors 17 are symmetrically arranged on the top of the support frame 16. Four support leg connectors 18 are symmetrically arranged on the left and right ends of the front and rear sides of the support base 1. Springs 19 are fitted at the bottom of the support leg connectors 18, and support legs 20 are fitted at the bottom of the springs 19. The medicine granules are poured into the middle of the three feeding baffles 12 on the left side plate 10. The path of the medicine granules is limited by the feeding baffles 12. Then the vibration motors 17 are started, and the vibration motors 17 drive the left side plate 10 to move the medicine granules. Plate 10, movable plate 2, and right side plate 11 vibrate. Due to the vibration, the granules on the left side plate 10 move towards the movable plate 2 until they reach the top of the movable plate 2. Due to the vibration, the granules on the movable plate 2 move towards the right side plate 11. During the movement of the granules on the movable plate 2, granules that are not up to size fall down through the filter holes 3 until they fall into the support base 1 for storage. After the granules on the movable plate 2 move to the right side plate 11, the path of the granules is limited by the discharge baffle 14. The vibrating right side plate 11 drives the granules to fall into the designated position, thus completing the granule feeding and filtration work.

[0024] Please see Figures 1-4 In this embodiment, the rear end of the rack 5 is inserted into the inner side of the concave frame 7, and the drive gear 9 meshes with the meshing gear 6. A left side plate 10 is provided on the left side of the top of the support base 1, and a right side plate 11 is provided on the right side of the top of the support base 1. Three feeding partitions 12 are provided at equal intervals on the top of the left side plate 10. Two baffles 13 are symmetrically provided on the left side of the top of the left side plate 10 corresponding to the position of the feeding partitions 12. Three discharge partitions 14 are provided at equal intervals on the top of the right side plate 11. When it is necessary to adjust the filter hole 3 according to the size of different medicine particles, the drive gear 9 is driven to rotate by the drive motor 8. The drive gear 9 drives the rack 5 to move backward by meshing with the meshing gear 6. The rack 5 drives the movable plate 2 to move backward through the connecting rod 4 until the filter hole 3 on the movable plate 2 that matches the size of the medicine particle is located below the three feeding partitions 12, and then stops moving. This realizes the function of adjusting the filter hole 3 and prevents the problem that the aperture on the filter plate cannot match the size of medicine particles of different sizes, thus affecting the filtration effect.

[0025] During operation, the granules are poured into the middle of the three feeding baffles 12 on the left side plate 10. The feeding baffles 12 limit the movement path of the granules. Then, the vibration motor 17 is started, which drives the left side plate 10, the movable plate 2, and the right side plate 11 to vibrate. Due to the vibration, the granules on the left side plate 10 move towards the movable plate 2 until they reach the top of the movable plate 2. Due to the vibration, the granules on the movable plate 2 move towards the right side plate 11. During the movement of the granules on the movable plate 2, any granules that are not up to size fall downwards through the filter holes 3 until they fall into the support base 1. Internally stored, after the medicine particles on the movable plate 2 move to the right side plate 11, the path of the medicine particles is limited by the discharge partition 14. The vibrating right side plate 11 drives the medicine particles to fall into the designated position. When it is necessary to adjust the filter hole 3 according to the size of different medicine particles, the drive motor 8 drives the drive gear 9 to rotate. The drive gear 9 drives the rack 5 to move backward through the meshing of the meshing gear 6. The rack 5 drives the movable plate 2 to move backward through the connecting rod 4 until the filter hole 3 on the movable plate 2 that matches the size of the medicine particles is located below the three feeding partitions 12, and then the movement stops, realizing the function of adjusting the filter hole 3.

[0026] Through the above steps, the drive motor 8 drives the drive gear 9 to rotate. The drive gear 9, through meshing with the meshing gear 6, drives the rack 5 to move backward. The rack 5, through the connecting rod 4, drives the movable plate 2 to move backward until the filter hole 3 on the movable plate 2, which is adapted to the size of the medicine granules, is located below the three feeding partitions 12, at which point the movement stops. This realizes the function of adjusting the filter hole 3, thus solving the problem of common medicine granulation devices that only include granulation and filtration functions. They can transport medicine granules and filter those that are not up to size, but lack the function of adjusting the filter hole 3. This makes it impossible to ensure that the diameter of the filter hole 3 can be adjusted according to different sizes of medicine granules, which can easily lead to the problem that the hole diameter on the filter plate cannot be adapted to different sizes of medicine granules, affecting the filtration effect.
