[0003] Early mixing techniques were relatively simple, often using manual stirring or simple mechanical stirring devices. Although mixing drums are constantly being improved, it is still difficult to guarantee a uniform mixing state throughout the drum. Insufficient mixing may occur in some areas, affecting the quality stability of pharmaceutical intermediates.

[0004] In view of this, we propose a pharmaceutical intermediate raw material mixing cylinder. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0027] Please see Figure 1 - Figure 4 This utility model provides a technical solution:

[0028] A pharmaceutical intermediate raw material mixing cylinder includes a chassis 1, with support columns 2 fixedly installed at the bottom of the chassis 1. In addition, there are three sets of support columns 2, and the three sets of support columns 2 are arranged in a circular array with equal spacing around the center of the circular cross section of the chassis 1, making the mixing cylinder body more stable. A cylinder body 3 is snapped into the center of the top of the chassis 1, and a bracket 4 is fixedly installed on the top of the chassis 1.

[0029] In one embodiment of this utility model, a mixing component 5 is provided at the top of the chassis 1. The mixing component 5 includes a servo motor 51. The servo motor 51 is fixedly installed at the top of the bracket 4. A rotating shaft 52 is fixedly installed at the bottom output end of the servo motor 51. One end of a connecting rod 53 is fixedly connected to the outer wall of the rotating shaft 52. A rotating rod 54 is rotatably installed at the other end of the connecting rod 53. A drive gear 55 is fixedly installed at the top of the rotating rod 54. A fixing post 56 is fixedly installed on the lower surface of the top of the bracket 4. A bevel gear disk 57 is fixedly installed at the bottom of the fixing post 56. The drive gear 55 meshes with the bevel gear disk 57. The rotating shaft 52 passes through the bevel gear disk 57. First, various pharmaceutical intermediate raw materials are added into the cylinder 3. Then, the servo motor 51 is started, which drives the rotating shaft 52 to begin rotating. When the rotating shaft 52 rotates, the connecting rod 53 moves synchronously. Since the other end of the connecting rod 53 is rotatably mounted to the rotating rod 54, the rotating rod 54 begins to revolve around the rotating shaft 52. A ball 58 is fixedly mounted on the rotating rod 54 and rotatably mounted on the bracket 4. A bottom rod 59 is fixedly mounted at the bottom end of the rotating rod 54, and a stirring rod 510 is fixedly mounted on the bottom rod 59. In addition, the movement trajectory of the stirring rod 510 does not intersect with the cylinder 3 to prevent the generation of fumes. Motion interference causes the ball 58 to roll in a circle on the support 4. This rolling provides a stable support point for the rotation of the rod 54, ensuring that the rod 54 does not deviate or wobble during its rotation. Furthermore, the rolling of the ball 58 reduces the friction of the rod 54 during its movement, making its movement smoother. Since the driving gear 55 meshes with the bevel gear disk 57 fixedly mounted at the bottom of the fixed column 56, when the rod 54 rotates, the driving gear 55 revolves around the center of the bevel gear disk 57 while simultaneously rotating on it due to the meshing relationship and self-adjustment. Due to the inertia of its own motion, the drive gear 55 will also rotate around its own axis. This combined motion of the drive gear 55 further drives the rotating rod 54 to move synchronously, so that the bottom rod 59 and the stirring rod 510 move synchronously. During the rotation, the stirring rod 510 stirs the material on the circumference of different radii inside the cylinder 3, which works in conjunction with the revolution of the rotating rod 54 to mix the material from different directions and layers. In addition, there are six sets of stirring rods 510, and the six sets of stirring rods 510 are all arranged in a circular array with equal spacing around the center of the circular cross section of the bottom rod 59, so that the material mixing effect is better.

[0030] In one embodiment of this utility model, an auxiliary component 6 is provided on the cylinder 3. The auxiliary component 6 includes an auger paddle 61. The auger paddle 61 is fixedly installed on the arc-shaped outer wall at the bottom end of the bottom rod 59, which improves the mixing effect of the material. When the bottom rod 59 rotates with the movement of the rotating rod 54, the auger paddle 61 rotates synchronously with the rotation of the bottom rod 59. The auger paddle 61 has a spiral structure. During rotation, it can generate both axial and radial forces on the material. The axial force causes the material to flow in the vertical direction of the cylinder 3, while the radial force causes the material to tumble and mix in the radial direction of the cylinder 3. This stirring method further improves the uniformity and effect of material mixing. In addition, a conical cover 62 is attached to the top of the cylinder 3. With the shielding effect of the conical cover 62, it can prevent the material from splashing out of the cylinder 3 during the stirring process. Furthermore, the diameter of the cross-sectional surface of the top of the conical cover 62 is smaller than the diameter of the cross-sectional surface of its bottom end. In addition, the conical cover 62 forms a funnel-like structure. During the material stirring process, when the material splashes or moves upward due to the stirring action of the stirring rod 510 and the auger paddle 61, the conical cover 62 can use its shape to block the splashed material and guide it back into the cylinder 3.

[0031] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the servo motor 51. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0032] Working principle: First, various pharmaceutical intermediate raw materials are added into the cylinder 3. Then, the servo motor 51 is started, which drives the rotating shaft 52 to begin rotating in a circular motion. When the rotating shaft 52 rotates, the connecting rod 53 moves synchronously. Since the other end of the connecting rod 53 is rotatably mounted to the rotating rod 54, the rotating rod 54 begins to revolve around the rotating shaft 52, causing the ball 58 to roll in a circular motion on the support 4. This rolling provides a stable support point for the rotation of the rotating rod 54, ensuring that the rotating rod 54 will not deviate or wobble during the rotation. On the other hand, the rolling of the ball 58 can reduce the friction of the rotating rod 54 during the movement, making the movement of the rotating rod 54 smoother. Due to the bevel teeth fixedly mounted on the bottom of the fixed column 56 and the drive gear 55, the rotation is smoother. The wheel 57 meshes with each other. When the rotating rod 54 revolves, the driving gear 55 revolves around the center of the bevel gear disk 57. At the same time, due to the meshing relationship and its own motion inertia, the driving gear 55 also rotates around its own axis. This compound motion of the driving gear 55 further drives the rotating rod 54 to move synchronously, so that the bottom rod 59 and the stirring rod 510 move synchronously. During the rotation, the stirring rod 510 stirs the material on the circumference of different radii inside the cylinder 3. It works in conjunction with the revolution of the rotating rod 54 to mix the material from different directions and layers, so that the material is fully mixed in the cylinder 3, achieving a better mixing effect and ensuring that various pharmaceutical intermediate raw materials can be uniformly fused together.

[0033] Furthermore, when the bottom rod 59 rotates with the movement of the rotating rod 54, the auger paddle 61 rotates synchronously with the rotation of the bottom rod 59. The auger paddle 61 has a spiral structure, and during rotation, it can generate both axial and radial forces on the material. The axial force causes the material to flow in the vertical direction of the cylinder 3, while the radial force causes the material to tumble and mix in the radial direction of the cylinder 3. This stirring method further improves the uniformity and effect of material mixing. Furthermore, the conical cover 62 forms a funnel-like structure. During the material mixing process, when the material splashes upward or moves due to the stirring action of the stirring rod 510 and the auger paddle 61, the conical cover 62 can use its shape to block the splashed material and guide it back into the cylinder 3, thereby shielding the material during the mixing process, preventing the material from splashing out of the cylinder 3, avoiding material waste and pollution to the working environment, and thus improving the practicality of the mixing cylinder body. After the mixing is completed, the bottom rod 59 and the conical cover 62 are removed, the cylinder 3 is taken off, and the mixture is poured out for subsequent processing.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
