Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical machinery, in particular to a powder grinding and mixing device for pharmaceutical raw materials. Background Art

[0002] As the basic material in the pharmaceutical process, the quality and processing method of pharmaceutical raw materials have a crucial impact on the efficacy and safety of the final drug. During the drug production process, raw materials usually need to be ground to achieve purposes such as improving solubility, increasing the reaction surface area, and promoting uniform mixing. For the ground pharmaceutical raw materials, in order to achieve the precise ratio in the formula and ensure the uniformity of the drug, they must be fully mixed through a stirring device. The powder grinding and mixing device for pharmaceutical raw materials occupies an important position in the pharmaceutical industry. As the core processing link, its mixing uniformity and efficiency have a decisive impact on the overall quality and production efficiency of drugs. Especially in the core link of grinding multiple pharmaceutical raw materials and then putting them into a mixing tank for stirring and mixing, a series of obvious limitations and technical problems have gradually emerged in the existing mixing and stirring mechanisms.

[0003] Specifically, in the mixing and stirring process of the existing powder grinding and mixing device for pharmaceutical raw materials, most of them adopt a stirring mechanism that rotates in a single direction. This single-direction stirring method has problems of poor mixing uniformity and low efficiency when facing the mixing of multiple pharmaceutical raw materials. Content of the Utility Model

[0004] The purpose of the utility model is to provide a powder grinding and mixing device for pharmaceutical raw materials, which solves the problems that in the existing powder grinding and mixing device for pharmaceutical raw materials in the prior art, most of them adopt a stirring mechanism that rotates in a single direction. When facing the mixing of multiple pharmaceutical raw materials, this single-direction stirring method has prominent problems such as poor mixing uniformity and low efficiency. Due to insufficient stirring, agglomeration is likely to occur between the raw materials, resulting in uneven mixing, which directly affects the quality and efficacy of the drug. At the same time, single-direction stirring also increases the time required for mixing, reduces production efficiency, and is difficult to meet the requirements of the modern pharmaceutical industry for high-efficiency and high-quality mixing. More seriously, uneven mixing may also bring potential safety risks, such as unstable efficacy or increased side effects caused by uneven distribution of drug components.

[0005] To achieve the above purpose, the utility model provides a powder grinding and mixing device for pharmaceutical raw materials, including a moving base, a mixing cylinder, and two vertical plates;

[0006] The two vertical plates are symmetrically arranged on both sides of the top of the moving base, and the mixing cylinder is arranged at the center of the top of the moving base and located between the two vertical plates;

Detailed implementation manners

[0022] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0023] Refer to Figures 1-5 , a pharmaceutical raw material grinding and mixing device, including a mobile base 101, a mixing cylinder 103 and two vertical plates 102;

[0024] The two vertical plates 102 are symmetrically arranged on both sides of the top of the mobile base 101, and the mixing cylinder 103 is arranged at the center of the top of the mobile base 101 and between the two vertical plates 102;

[0025] On one side of each of the two vertical plates 102 close to each other, there is provided a mounting ring plate 108 adapted to the outer circle of the mixing cylinder 103 and bolted and fixed. One side of the mounting ring plate 108 is fixedly connected to a rotating rod 107 rotatably connected to the side wall of the vertical plate 102;

[0026] A stirring system is provided inside the mixing drum 103, a material inlet and outlet structure is connected to the top of the mixing drum 103, a containing bin 104 is provided at the top center of the movable base 101, a driving assembly is installed on the side wall of the vertical plate 102 on one side, and an output shaft of the driving assembly passes through the vertical plate 102 through a shaft sleeve and is transmission-connected to the end of the rotating rod 107.

[0027] Furthermore, the driving assembly includes a driving motor 109, which is connected to the side wall of the vertical plate 102 through a mounting sleeve 112, and the output shaft of the driving motor 109 is drivingly connected to a driving gear plate 110 that is rotatably connected to the side wall of the vertical plate 102. The top of the driving gear plate 110 is connected to a driven gear plate 111 through a tooth meshing engagement, and one side of the driven gear plate 111 is fixedly connected to a shaft rod with one end passing through the shaft sleeve and penetrating the vertical plate 102, and one end of the shaft rod is connected to the end of an adjacent rotating rod 107. Through the coordinated arrangement of the driving motor 109, the mounting sleeve 112, the driving gear plate 110 and the driven gear plate 111 in the driving assembly, after the driving motor 109 is started in the working process, its output shaft drives the driving gear plate 110 to rotate, and then drives the driven gear plate 111 to rotate through the tooth meshing engagement, and finally drives the mixing barrel 103 to rotate around its axis through the shaft rod and the rotating rod 107. This arrangement achieves the effect of efficiently and stably driving the mixing drum 103 to rotate, ensuring the smooth progress of the mixing process.

[0028] Furthermore, fixing rods 113 are fixedly connected to both sides of the mounting sleeve 112, and one end of the fixing rod 113 is fixedly connected to the side wall bolts of the vertical plate 102. The fixing rods 113 on both sides of the mounting sleeve 112 are fixedly connected to the side walls of the vertical plate 102 by bolts. During the working process, the fixing rods 113 provide a stable support for the driving motor 109 and the mounting sleeve 112, ensuring the stability and reliability of the driving assembly during the mixing process, thereby improving the mixing efficiency and service life of the entire equipment.

[0029] Furthermore, the material inlet and outlet structure includes a conical barrel 115 connected to the top of the mixing barrel 103 and a feed hopper 117 connected to the end of the conical barrel 115. The internal thread of the feed hopper 117 is connected to a plug 116. Through the coordinated arrangement of the conical barrel 115, the feed hopper 117 and the plug 116 in the material inlet and outlet structure, raw materials can be conveniently added to the mixing barrel 103 through the feed hopper 117 during the work process. After mixing, the mixed raw materials can be discharged by opening the plug 116. This arrangement achieves the effect of convenient and efficient material inlet and outlet, and improves the convenience of operation and mixing efficiency of the equipment.

[0030] Further, the stirring system includes a mixing motor 114 installed at the center of the bottom of the mixing cylinder 103 and a stirring rod 118 disposed inside the mixing cylinder 103. The output shaft of the mixing motor 114 passes through the bottom of the mixing cylinder 103 through a bushing and is drivingly connected to the end of the stirring rod 118. Through the cooperative setting of the mixing motor 114 and the stirring rod 118 in the stirring system, after the mixing motor 114 is started during the working process, its output shaft drives the stirring rod 118 to perform stirring and mixing inside the mixing cylinder 103. This setting achieves the effect of fully and evenly stirring the raw materials, improving the uniformity and quality of the mixing.

[0031] Further, a placement groove 105 adapted to the storage bin 104 is formed at the center of the top of the moving base 101, and a handle 106 is fixedly connected to one side of the top of the moving base 101. Through the setting of the placement groove 105 at the center of the top of the moving base 101 and the handle 106 on one side, during the working process, the storage bin 104 can be conveniently placed in the placement groove 105, and the entire device can be moved through the handle 106. This setting achieves the effect of conveniently and quickly moving and placing the device, improving the flexibility and practicality of the device.

[0032] In summary: when using the present pharmaceutical raw material grinding and mixing equipment, first move the entire equipment to a suitable working position through the handle 106 on one side of the mobile base 101, and ensure its stability. Subsequently, place the storage bin 104 in the placement groove 105 at the top center of the mobile base 101 to receive the mixed pharmaceutical raw materials. Next, add the ground pharmaceutical raw materials through the feed and discharge structure at the top of the mixing barrel 103, specifically, add the raw materials through the conical barrel 115 and the feed hopper 117, and use the plug 116 to close the feed hopper 117 during the mixing process. At this time, the mixing barrel 103 is fixedly connected by bolts to the mounting ring plates 108 on the two vertical plates 102, and the internal stirring system and drive assembly are ready. When the drive assembly on the vertical plate 102 on one side is started, the drive motor 109 starts to work through the stable support of the mounting sleeve 112 and the fixed rod 113, and its output shaft drives the driving gear plate 110 to rotate. The driving gear plate 110 drives the driven gear plate 111 to rotate through the engagement of the teeth, and then drives the mixing drum 103 to rotate around its axis through the shaft and the rotating rod 107. At the same time, the mixing motor 114 at the bottom of the mixing drum 103 is also started, and its output shaft passes through the bottom of the mixing drum 103 through the shaft sleeve and is connected to the end of the stirring rod 118, driving the stirring rod 118 to stir and mix inside the mixing drum 103. Since the overall rotation of the mixing drum 103 is different from the stirring direction of the stirring system, the two cooperate with each other so that the internal grinding raw materials can be mixed more fully and evenly. After the mixing is completed, by opening the plug 116, the mixed pharmaceutical raw materials can be discharged from the mixing drum 103 through the conical barrel 115 and the feed hopper 117, and fall into the storage bin 104. In the whole work process, each component cooperates with each other to achieve an efficient and stable mixing effect.

[0033] This technical solution provides a new type of pharmaceutical raw material grinding and mixing equipment, which realizes more sufficient and uniform mixing of the grinding raw materials through the overall rotation of the mixing drum 103 and the mutual cooperation of the internal stirring system. Specifically, the overall rotation of the mixing drum 103 is realized by the coordinated setting of the driving motor 109, the mounting sleeve 112, the driving gear plate 110 and the driven gear plate 111 in the driving assembly. This setting ensures the smooth progress of the mixing process and improves the uniformity of the mixing. At the same time, the internal stirring system fully and evenly stirs the raw materials through the coordinated setting of the mixing motor 114 and the stirring rod 118, further improving the quality and efficiency of the mixing.

[0034] In addition, the device also achieves convenient and efficient feeding and discharging effects by optimizing the design of the feeding and discharging structure, that is, the cooperative setting of the conical cylinder 115, the feeding hopper 117 and the plug 116, improving the operation convenience and mixing efficiency of the device. At the same time, the placement groove 105 at the center of the top of the mobile base 101 and the side handle 106 are provided, enabling the device to be moved and placed conveniently and quickly, enhancing the flexibility and practicality of the device.

[0035] Through the ingenious cooperation and setting of each component, this technical solution not only effectively solves the problems of poor mixing uniformity and low efficiency in the prior art, but also meets the requirements of the modern pharmaceutical industry for high-efficiency and high-quality mixing. This device has significant technical advantages and practical value, providing strong support for the sustainable development of the pharmaceutical industry.

Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
