Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment technology, specifically relating to a large-scale pharmaceutical powder mixing equipment. Background Technology

[0002] In pharmaceutical manufacturing, powder mixing is an indispensable and crucial step. Its core purpose is to achieve a highly uniform physical mixture of various active pharmaceutical ingredients (APIs), excipients, or functional powders to ensure the consistency, safety, and efficacy of the final product.

[0003] In existing technologies, pharmaceutical powder mixing typically employs mixing equipment, especially large-scale pharmaceutical powder mixing equipment, which can hold more pharmaceutical powder and meet the needs of pharmaceutical production. However, large-scale pharmaceutical powder mixing equipment has a large mixing chamber with a considerable height, usually exceeding the height of an adult. After the mixing chamber stops rotating, it is impossible to ensure that the discharge port faces downwards. Furthermore, the feeding port is located at the top of the mixing chamber before mixing, which is inconvenient for feeding and requires the use of lifting equipment, resulting in poor practicality. Utility Model Content

[0004] This utility model provides a large-scale pharmaceutical powder mixing device, which aims to solve the problem of poor practicality caused by the inconvenience of feeding and discharging in existing large-scale pharmaceutical powder mixing devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a large-scale pharmaceutical powder mixing device, comprising:

[0006] A rack provides installation space;

[0007] A mixing tank is located in the installation space and is rotatably connected to the frame, with its rotation axis set horizontally; the mixing tank has a feeding port and a discharging port.

[0008] A drive assembly is mounted on the frame and connected to the rotating shaft of the mixing tank. The drive assembly is used to drive the mixing tank to rotate forward so that the powder is mixed.

[0009] An adjustment component, disposed on the drive component, is used to drive the mixing box to rotate forward until the height of the feeding port decreases after the drive component stops working, or to make the discharge port face downwards.

[0010] In one possible implementation, the driving component includes:

[0011] The drive is fixed to the frame;

[0012] A speed reduction transmission structure is mounted on the frame, the speed reduction transmission structure having a power input end connected to the driver and a power output end connected to the mixing tank shaft.

[0013] In one possible implementation, the speed reduction transmission structure includes:

[0014] Fixed box, with cavity;

[0015] The first rotating shaft is rotatably mounted on the fixed box, with one end extending out of the cavity and connected to the driver, and the other end provided with a first helical gear;

[0016] The second rotating shaft is rotatably mounted on the fixed box. The second rotating shaft is perpendicular to the first rotating shaft. The second rotating shaft is provided with a second helical gear that meshes with the first helical gear, and also with a first spur gear.

[0017] The third rotating shaft is rotatably mounted on the fixed box and is parallel and spaced apart from the second rotating shaft. One end of the third rotating shaft extends out of the cavity and is connected to the rotating shaft of the mixing box. The third rotating shaft is provided with a second spur gear that meshes with the first spur gear. The third rotating shaft is used to drive the mixing box to rotate in the forward direction.

[0018] In one possible implementation, a first one-way bearing is provided between the third shaft and the second spur gear.

[0019] In one possible implementation, the regulating component includes:

[0020] The worm gear is mounted on the third rotating shaft;

[0021] A second one-way bearing is disposed between the worm gear and the third shaft;

[0022] A worm gear meshes with the worm wheel, with one end of the worm gear extending out of the cavity.

[0023] In one possible implementation, the extended end of the worm gear is connected to a handwheel.

[0024] In this implementation, the drive component ensures that the mixing tank rotates on the frame, thereby ensuring thorough mixing of the powder within the mixing tank. The adjustment component ensures that, after mixing, the discharge port of the mixing tank is adjusted to face downwards for proper discharge. Furthermore, the adjustment component also allows for lowering the height of the mixing tank's discharge port before feeding to accommodate the height of the operator, facilitating the precise filling of the required amount of powder, making it highly practical.

[0033] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Please see Figure 1 The large-scale pharmaceutical powder mixing equipment provided by this utility model will now be described.

[0035] Large-scale pharmaceutical powder mixing equipment holds a larger volume of material, resulting in a slower rotation speed of the mixing tank 20 during the mixing process. Simultaneously, the weight of the pharmaceutical powder exceeds the weight of the mixing tank 20. Consequently, the position of the discharge port 22 or the feeding port 21 is not fixed after mixing. Regarding the discharge process, the discharge port 22 needs to be adjusted to face downwards, which is inconvenient and requires constant opening and closing of the drive. Furthermore, setting the discharge port 22 downwards inevitably results in the feeding port 21 being located at the top of the mixing tank 20, exceeding the height of an adult, making it inconvenient for workers to feed the material.

[0036] See Figure 1A large-scale pharmaceutical powder mixing device includes a frame 10, a mixing tank 20, a drive assembly 30, and an adjustment assembly 40. The frame 10 has installation space. The mixing tank 20 is located in the installation space and is rotatably connected to the frame 10, with its rotation axis horizontally positioned. The mixing tank 20 has a feeding port 21 and a discharging port 22. The drive assembly 30 is mounted on the frame 10 and connected to the rotating shaft of the mixing tank 20. The drive assembly 30 can drive the mixing tank 20 to rotate forward to mix the pharmaceutical powder. The adjustment assembly 40 is mounted on the drive adjustment assembly 40 and can, after the drive adjustment assembly 40 stops working, drive the mixing tank 20 to rotate forward until the height of the feeding port 21 decreases, or to make the discharging port 22 face downwards.

[0037] Compared with the prior art, the large-scale powder mixing equipment provided in this embodiment ensures that the driving component 30 can rotate the mixing tank 20 on the frame 10, thereby ensuring that the powder in the mixing tank 20 is fully mixed. The adjusting component 40 ensures that after mixing, the discharge port 22 of the mixing tank 20 is adjusted to face downwards for discharge. Furthermore, the adjusting component 40 can also lower the height of the feeding port 21 of the mixing tank 20 before feeding to accommodate the height of the operator, thus facilitating the filling of a fixed amount of powder, making it highly practical.

[0038] In some embodiments, the driving component 30 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The drive assembly 30 includes a driver 31 and a reduction gear transmission structure 32. The driver 31 is fixed on the frame 10. The reduction gear transmission structure 32 is disposed on the frame 10 and has a power input end connected to the driver 31 and a power output end connected to the rotating shaft of the mixing box 20.

[0039] The driver 31 provides power and transmits the power to the mixing box 20 through the reduction gear transmission structure 32, which can ensure the stable rotation of the mixing box 20.

[0040] In some embodiments, the aforementioned speed reduction transmission structure 32 may adopt the following... Figure 2 The structure shown. See also Figure 2The reduction gear transmission structure 32 includes a fixed housing 321, a first rotating shaft 322, a first helical gear 323, a second rotating shaft 324, a second helical gear 325, a first spur gear 326, a third rotating shaft 327, a second helical gear 325, and a manual adjustment component. The fixed housing 321 has a cavity. The first rotating shaft 322 is rotatably mounted on the fixed housing 321, with one end extending out of the cavity and connected to the driver 31, and the other end equipped with the first helical gear 323. The second rotating shaft 324 is rotatably mounted on the fixed housing 321, perpendicular to the first rotating shaft 322, and is equipped with a second helical gear 325 that meshes with the first helical gear 323, and also has a first spur gear 326 mounted on it. The third rotating shaft 327 is rotatably mounted on the fixed box 321 and is parallel and spaced apart from the second rotating shaft 324. One end of the third rotating shaft 327 extends out of the cavity and is connected to the rotating shaft of the mixing box 20. The third rotating shaft 327 is provided with a second spur gear 328 that meshes with the first spur gear 326. The third rotating shaft 327 can drive the mixing box 20 to rotate in the forward direction.

[0041] The speed reduction transmission structure 32 drives the second helical gear 325 to rotate via the first helical gear 323 connected to the first rotating shaft 322, which in turn drives the second rotating shaft 324 to rotate. The first spur gear 326 on the second rotating shaft 324 drives the second spur gear 328 on the third rotating shaft 327 to rotate, thereby realizing the rotation of the third rotating shaft 327. At the same time, the power is transmitted to the rotating shaft of the mixing box 20, causing the mixing box 20 to rotate on the horizontal axis.

[0042] Specifically, the diameter of the first helical gear 323 can be smaller than the diameter of the second helical gear 325, and the diameter of the first spur gear 326 can be smaller than the diameter of the second spur gear 328, in order to achieve the deceleration effect.

[0043] In some embodiments, the third rotating shaft 327 and the second spur gear 328 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 A first one-way bearing 329 is provided between the third rotating shaft 327 and the second spur gear 328.

[0044] When the adjustment component 40 is working, the mixing box 20 also needs to be adjusted to rotate. At this time, the rotating shaft of the mixing box 20 will drive the third rotating shaft 327 to rotate. In order to prevent the third rotating shaft 327 from transmitting power to the second spur gear 328, a first one-way bearing 329 is introduced. The inner ring of the first one-way bearing 329 is connected to the third rotating shaft 327, and the outer ring is connected to the second spur gear 328. The second spur gear 328 can drive the third rotating shaft 327 to rotate in the forward direction, but the third rotating shaft 327 cannot drive the second spur gear 328 to rotate in the forward direction. This can reduce the resistance during the adjustment process and also protect the driver 31.

[0045] In some embodiments, the adjustment component 40 may employ, for example... Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The adjusting assembly 40 includes a worm gear 41, a second one-way bearing 42, and a worm 43. The worm gear 41 is sleeved on the third rotating shaft 327. The second one-way bearing 42 is disposed between the worm gear 41 and the third rotating shaft 327. The worm 43 meshes with the worm gear 41, and one end of the worm 43 extends out of the cavity.

[0046] The worm gear 41 and the second spur gear 328 are spaced apart on the axis of the third rotating shaft 327, and a second one-way bearing 42 is provided between the worm gear 41 and the third rotating shaft 327. Specifically, the inner ring of the second one-way bearing 42 is connected to the third rotating shaft 327, and the outer ring is connected to the worm gear 41. When the second spur gear 328 drives the third rotating shaft 327 to rotate in the forward direction, the second one-way bearing 42 prevents the third rotating shaft 327 from transmitting power to the worm gear 41. After the driver 31 stops working, the worm 43 drives the worm gear 41 to rotate in the forward direction, ensuring that the power of the worm gear 41 is transmitted to the third rotating shaft 327, thereby realizing the forward rotation of the third rotating shaft 327. The power is then transmitted to the mixing box 20 through the third rotating shaft 327, realizing the tilting adjustment of the mixing box 20.

[0047] This structure facilitates the adjustment of the mixing tank 20, ensuring that the discharge port 22 of the mixing tank 20 faces downwards, or that the height of the feeding port 21 is lowered. This eliminates the previous inconvenient adjustment methods, saves power, avoids high-frequency opening and closing of the driver 31, and extends the service life of the driver 31.

[0048] In some embodiments, the worm gear 43 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The protruding end of the worm gear 43 is connected to a hand control wheel 44, which is located outside the fixed box 321, making it convenient for staff to manually control and further facilitating the adjustment process.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
