[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a pulverizing and drying device for pharmaceutical raw materials. The drying mechanism 1 includes a support column 101, a processing box 102, and a dryer 103.

The drying mechanism 1 is used to dry the pulverized raw materials, the pulverizing mechanism 2 is used to pulverize the raw materials, and the cooperating mechanism 4 is used to assist the drying process.

[0028] Specifically, the drying mechanism 1, the pulverizing mechanism 2, and the coordinating mechanism 4 solve the problems of uneven drying, low drying efficiency, and easy agglomeration of raw materials after pulverization in the existing pharmaceutical process. By setting the pulverizing mechanism 2 inside the processing box 102 and configuring the drying mechanism 1 and the coordinating mechanism 4 outside the processing box 102, continuous operation of pulverization and drying is realized. The dryer 103 in the drying mechanism 1 can perform efficient hot air drying on the pulverized raw materials, while the coordinating mechanism 4 assists the drying process through physical means such as vibration, so that the raw material particles are evenly dispersed, thereby improving the drying effect and production efficiency.

[0030] Example 2

[0031] The second embodiment of this utility model provides a pulverizing and drying device for pharmaceutical raw materials. The pulverizing mechanism 2 includes a servo motor 201, a pulverizing roller 202, a support plate 203, and a mating plate 204. The output end of the servo motor 201 is fixedly connected to the inner wall of the pulverizing roller 202. The surface of the pulverizing roller 202 is rotatably connected to the inner wall of the support plate 203 via a sliding groove. The lower end of the support plate 203 is provided with the mating plate 204, and the outer side of the mating plate 204 is provided with an auxiliary mechanism 3. The auxiliary mechanism 3 includes a transmission plate 301, a drive screw 302, a transmission component 303, a tensioning wheel 304, and a stepper motor 305. The inner wall of the transmission plate 301 is threadedly connected to the surface of the drive screw 302, and the lower end of the drive screw 302 is drive-connected to the surface of the transmission component 303. The surface of component 303 is connected to the surface of tensioning wheel 304, the inner surface of transmission component 303 is connected to the output end of stepper motor 305, the surface of servo motor 201 is fixedly connected to the upper end of processing box 102, the two sides of support plate 203 are fixedly connected to the inner wall of processing box 102, the surface of mating plate 204 is slidably connected to the inner wall of processing box 102 through a sliding groove, the two sides of mating plate 204 are fixedly connected to the surface of transmission plate 301, the two ends of active screw 302 are rotatably connected to the inner walls of both ends of processing box 102, the surface of tensioning wheel 304 is rotatably connected to the lower end of processing box 102 through a rotating shaft, the surface of stepper motor 305 is fixedly connected to the lower end of processing box 102, and the surface of transmission plate 301 is slidably connected to the inner walls of both sides of processing box 102 through a sliding groove.

[0032] Specifically, the pulverizing mechanism 2 solves the problems of uneven raw material pulverization, inconvenient particle size adjustment, and unstable equipment transmission in existing pharmaceutical processes. By setting a servo motor 201 to drive the pulverizing roller 202 to rotate, and combining it with an adjustable mating plate 204, it achieves efficient pulverization of raw materials. At the same time, by using a stepper motor 305 in conjunction with the active screw 302 and the transmission plate 301, it is possible to accurately adjust the distance between the pulverizing roller 202 and the mating plate 204 to meet the particle size requirements of different formulations. The setting of the transmission component 303 and the tensioning wheel 304 improves the transmission stability and ensures that the pulverization process is continuous and reliable.

[0033] Furthermore, to meet the requirements of different formulations for raw material particle size, the distance between the pulverizing roller 202 and the mating plate 204 needs to be adjusted according to actual needs. This adjustment process is achieved by a stepper motor 305 located at the bottom of the processing box 102, whose output end is connected to a transmission component 303, which drives the active screws 302 on both sides of the processing box 102 to rotate. To ensure a smooth and reliable transmission process, a tensioning wheel 304 is provided at the bottom of the processing box 102 to maintain the tension of the transmission component 303. A transmission plate 301 is provided on the surface of the active screw 302, and the two are connected by a threaded engagement. When the active screw 302 rotates, the transmission plate 301 moves along the sliding groove direction on the inner wall of the processing box 102. Since both ends of the mating plate 204 are fixed with transmission plates 301, the movement of the transmission plates 301 can drive the mating plate 204 to make linear displacement, thereby realizing the precise adjustment of the distance between the crushing roller 202 and the mating plate 204. After the adjustment is completed, the raw material to be processed is put into the processing box 102 from the feed port. At this time, the servo motor 201 is started, and its output end drives the crushing roller 202 to rotate at high speed. The raw material falls into the gap area between the crushing roller 202 and the mating plate 204 under the action of gravity. Under the relative motion of the two, it is effectively crushed. The size of the crushed particles depends on the distance between the crushing roller 202 and the mating plate 204: the smaller the distance, the finer the particles; conversely, the larger the distance, the coarser the particles.

[0034] Example 3

[0035] The third embodiment of this utility model provides a pulverizing and drying device for pharmaceutical raw materials. The cooperating mechanism 4 includes a guide plate 401, a filter plate 402, a telescopic rod 403, a spring 404, and a vibration motor 405. The lower two sides of the guide plate 401 are fixedly connected to the surfaces of the two filter plates 402. The lower ends of the filter plates 402 are fixedly connected to the upper ends of the telescopic rod 403. The spring 404 is sleeved on the surface of the telescopic rod 403. The outer surface of the processing box 102 is fixedly connected to the surface of the vibration motor 405. The surface of the filter plates 402 is slidably connected to the inner wall of the processing box 102. The lower end of the telescopic rod 403 is fixedly connected to the bottom of the processing box 102.

[0036] Specifically, the cooperating mechanism 4 solves the problems of uneven material distribution after crushing, low drying efficiency, and easy particle accumulation in existing systems. By setting up the combination of the guide plate 401 and the filter plate 402, the crushed raw material is uniformly guided to the surface of the filter plate 402. The vibration motor 405 drives the filter plate 402 to vibrate at high frequency, which effectively prevents material accumulation and promotes uniform particle dispersion. At the same time, the cooperative structure of the telescopic rod 403 and the spring 404 enhances the buffering performance during vibration while ensuring stable support of the filter plate 402, thereby improving the stability of system operation.

[0037] Furthermore, the pulverized material falls through the mixing plate 204 into the guide plate 401 below, and is guided by the guide plate 401 to the filter plates 402 on both sides of the processing box 102. Then it enters the drying stage. The system is equipped with a dryer 103, which can perform hot air drying on the particles on the filter plates 402. At the same time, the vibration motor 405 drives the filter plates 402 to generate high-frequency vibration, so that the particles are evenly distributed and continuously moving on the filter plates 402, which helps to improve drying efficiency and prevent material accumulation. The fully dried particles are finally discharged from the processing box 102 through the filter plates 402, completing the entire continuous operation process of pulverization and drying.

[0038] Working principle:

[0039] In pharmaceutical manufacturing, the crushing and drying of raw materials is a crucial pretreatment step. To meet the particle size requirements of different formulations, the distance between the crushing roller 202 and the mating plate 204 needs to be adjusted according to actual needs. This adjustment is achieved by a stepper motor 305 located at the bottom of the processing chamber 102, whose output end is connected to a transmission component 303, which drives the active screws 302 on both sides of the processing chamber 102 to rotate. To ensure a smooth and reliable transmission process, a tensioning wheel 304 is provided at the bottom of the processing chamber 102 to maintain the tension of the transmission component 303. A transmission plate 301 is provided on the surface of the active screw 302, and the two are threaded together. When the active screw 302 rotates, the transmission plate 301 moves along the sliding groove on the inner wall of the processing chamber 102. Since the transmission plates 301 are fixed at both ends of the mating plate 204, the movement of the transmission plate 301 can drive the mating plate 204 to make a linear displacement, thereby achieving precise adjustment of the distance between the crushing roller 202 and the mating plate 204. After the adjustment is completed, the material to be processed is... Raw materials are fed into the processing box 102 through the feed inlet. At this time, the servo motor 201 is started, and its output drives the crushing roller 202 to rotate at high speed. Under the action of gravity, the raw materials fall into the gap area between the crushing roller 202 and the mating plate 204. Under the relative motion of the two, they are effectively crushed. The size of the crushed particles depends on the distance between the crushing roller 202 and the mating plate 204: the smaller the distance, the finer the particles; conversely, the larger the distance, the coarser the particles. The crushed material falls into the guide plate 401 below through the mating plate 204, and is guided by the guide plate 401 to the filter plates 402 on both sides of the processing box 102. Then it enters the drying stage. The system is equipped with a dryer 103, which can perform hot air drying on the particles on the filter plates 402. At the same time, the vibration motor 405 drives the filter plates 402 to generate high-frequency vibration, so that the particles are evenly distributed and continuously moving on the filter plates 402, which helps to improve the drying efficiency and prevent material accumulation. The fully dried particles are finally discharged from the processing box 102 through the filter plates 402, completing the entire continuous operation process of crushing and drying.

[0040] In summary, the coordinated operation of the pulverizing, drying, and blending mechanisms enables continuous operation of the raw material pulverizing and drying process. The pulverizing mechanism can adjust the pulverizing gap as required to ensure that the particle size meets the formulation requirements. The blending mechanism, through the combination of guide plates, filter plates, and vibrating motors, ensures that the pulverized material is evenly distributed and stably transported to the drying area, avoiding material accumulation. The drying mechanism uses efficient hot air drying on the filter plates, thereby improving the efficiency and quality stability of the pharmaceutical pretreatment process and meeting the requirements of high-quality pharmaceutical production.
