Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production, in particular to a high-efficiency wet mixing granulator. Background Technique

[0002] The wet granulator used in pharmaceutical production is a granulating device widely used in the pharmaceutical industry. This device mainly mixes powder materials and binders in a container and uses a high-speed granulating knife to cut them into uniform wet granules, so as to obtain the required granule characteristics, such as fluidity, compressibility and dissolution rate. The wet granulating machine plays a crucial role in pharmaceutical production. It can not only improve production efficiency, but also ensure the quality and consistency of pharmaceutical granules.

[0003] For some existing mixing granulators, the stirring blades or stirring rollers used for stirring are mostly at a fixed angle. When facing different types of pharmaceutical production, due to the different properties of raw materials, the stirring force and speed need to be adjusted during stirring. The inclination angle of the stirring blades will affect the stirring intensity and efficiency during pharmaceutical production. However, if the angle is adjusted improperly, it will not only cause additional chemical or physical reactions of the raw materials and change the properties of the raw materials, but also damage the equipment. At present, when adjusting the angle, it is manually adjusted by workers. When facing the preparation of different pharmaceuticals, the operators need to frequently stop the machine for adjustment, which is rather cumbersome.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-5 , the present invention provides a technical solution: including a first box body 10 and a second box body 11 fixedly connected to the bottom of the first box body 10. Both the first box body 10 and the second box body 11 are hollow structures. At the center of the inner wall of the bottom of the first box body 10, there is a second rotating shaft 25. At the bottom end of the outer arc wall of the second rotating shaft 25, there is a first fixing column 26 sleeved. In the middle of the outer arc wall of the second rotating shaft 25, there is a second sleeve column 33 sleeved. At the top end of the outer arc wall of the second rotating shaft 25, there is a first sleeve column 32 sleeved. At the bottom end of the outer arc wall of the second sleeve column 33, there are four stirring arms 35 fixedly connected and distributed in an annular array. The stirring arms 35 are L-shaped. Inside the horizontal parts of the four stirring arms 35, there is the same adjusting mechanism 40. Inside the second rotating shaft 25 at the position corresponding to the adjusting mechanism 40 on the outer arc wall, there is a fixing mechanism 50. The adjusting mechanism 40 includes an outer tooth ring 41 rotatably connected to the middle and lower part inside the second sleeve column 33. On the inner arc wall of the outer tooth ring 41, there is an inner tooth ring 45 fixedly connected. At the bottom inner walls of the four stirring arms 35 far from the second sleeve column 33, there are horizontally rotatably connected sprockets 42. The outer tooth ring 41 and the outer sides of the four sprockets 42 are all meshed with the same chain 43. The chain 43 is located inside the second sleeve column 33 and the horizontal parts of the stirring arms 35. At the corners where the chain 43 is meshed with the outer tooth ring 41 and far from the outer tooth ring 41, there are tension wheels 44 abutted. The tension wheels 44 are located inside the second sleeve column 33. In the middle of the outer arc wall of the tension wheels 44, there are tooth grooves, and the tooth grooves are adapted to the teeth of the outer tooth ring 41.

[0034] It should be noted that: the tooth structures of the outer tooth ring 41 and the sprockets 42 are the same. At the center of its top, there is a vertically penetrating second channel. The cross-sectional radius of the second channel is larger than that of the first channel. The inner tooth ring 45 is fixedly connected to the inner arc wall of the second channel. The inner ring cross-sectional radius of the inner tooth ring 45 is also larger than that of the first channel, that is, both the outer tooth ring 41 and the inner tooth ring 45 are located inside the second sleeve column 33 and do not contact the outside world;

[0035] Here, the chain 43 is cross-shaped, that is, it adapts to the positions of the four sprockets 42. The meshing connections between the chain 43 and the outer tooth ring 41 are all supported by the tension wheels 44. In this way, there are four meshing connections between the chain 43 and the outer tooth ring 41. On the outside of each connection, there are two tension wheels 44 abutted. This is not only to ensure the meshing connection between the outer tooth ring 41 and the chain 43, but also to keep the chain 43 from loosening.

[0036] Please refer toFigures 1-5 , the present utility model provides a technical solution: a vertically penetrating channel one is provided at the center of the top of the second sleeve column 33, the adjusting mechanism 40 is not located within the channel one, the horizontal portion of the second stirring arm 35 is fixedly connected to the outer arc wall of the second sleeve column 33, the vertical portion of the second stirring arm 35 is arranged away from the second box body 11, the second stirring arm 35 is a hollow structure, a placement groove one for installing the adjusting mechanism 40 is provided inside the second sleeve column 33, and the inside of the second stirring arm 35 communicates with the placement groove one. The second rotating shaft 25 is divided into two parts, and the fixing mechanism 50 is located between the upper half and the lower half.

[0037] It should be noted that: the horizontal portion of the second stirring arm 35 is a hollow structure, and the vertical portion at the other end of the second stirring arm 35 away from the second sleeve column 33 is actually the stirring blade. The second rotating shaft 25 can be regarded as being spliced by two coaxial and identically structured rotating shafts, but a fixing mechanism 50 is provided at the splicing position of the two.

[0038] Please refer to Figures 1-5 , the present utility model provides a technical solution: at the center of the bottom of the upper half of the second rotating shaft 25 and at the center of the top of the lower half of the second rotating shaft 25, turntables 51 are fixedly connected. On the side walls of the two turntables 51 close to each other, a same fixing column three is rotatably connected. The fixing mechanism 50 includes a plurality of fixing rods 52 fixedly connected to the outer arc wall of the fixing column three and distributed in an annular array. The end of the fixing rod 52 away from the fixing column three is rotatably connected to a pawl 53, and the pawl 53 is meshed with the internal gear ring 45. On the side walls of the two turntables 51 close to each other, a plurality of fixing columns two 55 are fixedly connected and distributed in an annular array. A plurality of the fixing columns two 55 are all located outside the fixing column three, and a plurality of the fixing columns two 55 correspond to a plurality of the pawls 53 one by one. A tension spring 54 is installed on the outer arc wall of the fixing column two 55, and the end of the tension spring 54 away from the fixing column two 55 is fixedly connected to the pawl 53.

[0039] It should be noted that: the fixing column three ensures that torque can be transmitted between the two parts of the second rotating shaft 25. The turntable 51 can also be regarded as the side wall of the two parts of the second rotating shaft 25 close to each other. When the fixing mechanism 50 is driven to rotate forward by the second rotating shaft 25, the turntable 51 will drive the tension spring 54 to further pull the pawl 53 to rotate inward and contract, reducing the friction between the pawl 53 and the teeth of the internal gear ring 45. When rotating in the reverse direction, the tension spring 54 is pushed in the reverse direction, and at the same time, the pawl 53 is pushed out to engage with the teeth of the internal gear ring 45.

[0040] Please refer to Figures 1-5, the present utility model provides a technical solution: both ends of the second rotating shaft 25 and the first fixed column 26 close to the second box body 11 penetrate through the inner wall of the bottom of the first box body 10. A driving mechanism 20 is provided inside the second box body 11. The driving mechanism 20 includes a horizontally arranged third bevel gear 24 fixedly connected to the bottom of the first fixed column 26. The bottom end of the outer arc wall of the second rotating shaft 25 is fixedly connected with a horizontally arranged second bevel gear 23. The third bevel gear 24 and the second bevel gear 23 are both located inside the second box body 11 and are symmetrically arranged about the center of the inside of the second box body 11. The bottom end of the second rotating shaft 25 is rotatably connected to the inner wall of the bottom of the second box body 11. The same side of the third bevel gear 24 and the second bevel gear 23 is meshed with the same vertical first bevel gear 22. The center of the side wall of the first bevel gear 22 away from the second rotating shaft 25 is fixedly connected with a first rotating shaft 21. One end of the first rotating shaft 21 away from the first bevel gear 22 is fixedly connected with a motor.

[0041] It should be noted that: the teeth of the third bevel gear 24 and the second bevel gear 23 are arranged oppositely, and the teeth of the first bevel gear 22 face the second rotating shaft 25. When the first bevel gear 22 rotates, it will drive the second bevel gear 23 and the third bevel gear 24 to rotate coaxially in opposite directions, thereby driving the first sleeve column 32 and the second sleeve column 33 in the stirring mechanism 30 to rotate coaxially in opposite directions, increasing the stirring effect and rate.

[0042] Please refer to Figures 1-5 , the present utility model provides a technical solution: a stirring mechanism 30 is provided at one end of the outer arc wall of the second rotating shaft 25 away from the inner wall of the bottom of the first box body 10. The stirring mechanism 30 includes a fixing cover 31 threadedly connected to the top of the second rotating shaft 25. The top end of the outer arc wall of the second rotating shaft 25 is sleeved with a first sleeve column 32. The first sleeve column 32 is located between the fixing cover 31 and the second sleeve column 33 and is in contact with the fixing cover 31 and the second sleeve column 33 respectively. Four stirring arms 34 arranged in an annular array are fixedly connected to the top end of the outer arc wall of the first sleeve column 32. The stirring arm 34 is L-shaped, its horizontal part is connected to the outer arc wall of the first sleeve column 32, and its vertical part faces the second box body 11. The ends of the stirring arm 34 and the stirring arm 35 close to each other on the side walls close to each other are both inclined surfaces.

[0043] It should be noted that: a threaded rod is fixedly connected to the top of the second rotating shaft 25, and the fixing cover 31 is threadedly connected to the threaded rod. A sealing ring is provided on the side wall of the first sleeve column 32 close to the fixing cover 31, and a sealing ring is provided on the side wall of the second sleeve column 33 close to the first sleeve column 32. When the fixing cover 31 moves to the bottom end of the threaded rod, the fixing cover 31, the first sleeve column 32 and the second sleeve column 33 are in close contact with each other to achieve sealing.

[0044] Please refer to Figures 1-5, the present utility model provides a technical solution: the length of the horizontal part of the stirring arm 34 is less than that of the horizontal part of the stirring arm 35, and the length of the vertical part of the stirring arm 34 is less than the distance from the horizontal part of the stirring arm 34 to the horizontal part of the stirring arm 35.

[0045] It should be noted that when the first sleeve column 32 and the second sleeve column 33 rotate, the stirring arm 34 and the stirring arm 35 on their outer arc walls will not contact each other, avoiding collision or even jamming.

[0046] Please refer to Figures 1-5 , the present utility model provides a technical solution: a plurality of vertical first sliding strips are arranged on the inner arc wall of the first sleeve column 32, a plurality of vertical sliding grooves are arranged on the outer arc wall of the end of the second rotating shaft 25 away from the second box body 11, a second sliding strip having the same structure as the first sliding strip is arranged at the top of the inner arc wall of the second sleeve column 33, and the first sliding strip and the second sliding strip are both adapted to the sliding grooves.

[0047] It should be noted that the first sliding strip and the second sliding strip facilitate the disassembly and installation of the first sleeve column 32 and the second sleeve column 33. A second groove is provided at the top of the second sleeve column 33, a ball is provided at the bottom of the first sleeve column 32, and the friction between the first sleeve column 32 and the second sleeve column 33 can be reduced when they rotate relative to each other. The sealing ring is located outside the groove.

[0048] Please refer to Figures 1-5 , the present utility model provides a technical solution: a plurality of arc-shaped fixing blocks are arranged at the bottom of the second sleeve column 33 in an annular array, grooves adapted to the arc-shaped fixing blocks are provided at corresponding positions at the top of the first fixing column 26, the cross-sectional radii of the middle part and the lower middle part of the outer arc wall of the second rotating shaft 25 are both smaller than the cross-sectional radius of the upper middle part of the outer arc wall of the second rotating shaft 25, and a top cover 12 is provided at the top of the first box body 10.

[0049] It should be noted that when the second sleeve column 33 is installed on the outside of the second rotating shaft 25 along the sliding groove, since the cross-sectional radii of the middle part and the lower middle part of the outer arc wall of the second rotating shaft 25 are small, that is, the outer arc wall of the second rotating shaft 25 does not directly contact the inner arc wall of the second sleeve column 33 and a moving space is reserved for the fixing mechanism 50, and the arc-shaped fixing blocks at the bottom of the second sleeve column 33 enable the first fixing column 26 to drive the second sleeve column 33 to rotate, and the top of the second rotating shaft 25 drives the first sleeve column 32 to rotate, and the two do not interfere with each other.

[0050] Working principle:

[0051] Pour the raw materials into the interior of the first box body 10, cover the top cover 12 and seal it well. The driving mechanism 20 drives the stirring mechanism 30 to stir the raw materials in the first box body 10. When it is necessary to adjust the inclination angle of the stirring blades, first pause the machine, and then rotate it slowly, so that the fixing mechanism 50 limits the internal gear ring 45 and then drives the adjusting mechanism 40 to operate, driving the stirring blades on the four stirring arms two 35 to rotate for angle adjustment. Then, the stirring mechanism 30 rotates forward to resume normal stirring, and the fixing mechanism 50, under the pulling of the tension spring 54, makes the pawl 53 no longer limit the internal gear ring 45, thus releasing the drive of the adjusting mechanism 40.
