Description

Technical Field

[0001] The utility model relates to the technical field related to medicine manufacturing, in particular to a medicinal granule size-forming device. Background Art

[0002] The granulation device is a commonly used device for the production of granules in the pharmaceutical manufacturing process. It is mainly used to impact and shear the granules or uneven granules that have agglomerated after granulation and drying under the action of the high-speed rotating stirring cone knife of the granulation device, and then discharge uniform granules through the mesh of the screen, and then mix or tablet press them. It is widely used in the raw material drug, chemical, pharmaceutical and other industries.

[0003] After extensive searching, it was discovered that the existing Chinese patent publication number is CN219896432U, which discloses a storage tank granulation device for drug preparation, including a granulation box, the top of which is fixedly connected to a drug storage tank, the top of which is fixedly connected to a granulation machine, a processing box fixedly connected to one side of the granulation box, a bottom plate slidably connected to the bottom of the processing box, a sealing plate symmetrically fixedly connected to the top of the bottom plate, a handle fixedly connected to the middle of the sealing plate, a storage box symmetrically placed on the top of the bottom plate, a partition fixedly connected to the middle of the top of the bottom plate, and a fan fixedly connected to the top of the processing box. The utility model can perform dust extraction during the granulation process, while preventing drug particles from being extracted and preventing large amounts of dust from overflowing. At the same time, it can quickly remove and collect drug particles, and simultaneously realize the installation of a new storage box, thereby eliminating the need for long-term downtime and facilitating the rapid completion of drug transportation.

[0004] In summary, the existing laboratory-produced granulator, which can obtain a controllable particle size range through operation, occupies a relatively large production area and has a high particle loss after use; and the overall structure of the equipment is strong and not easy to disassemble, which is very inconvenient for staff to operate.

[0005] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a medicinal granule granulation device to make it more valuable for industrial use. Utility Model Content

A feed port 12 is provided on one side of the upper body 6 near the top, and a discharge port 11 is provided at the bottom of the lower body 10. The inclined feed port 12, combined with the speed adjustment, facilitates feeding and adjusting the speed and effect of the product pelletizing within the body.

[0033] A rotating shaft 13 distributed along the vertical direction is installed in the upper body 6, the servo motor 4 is connected to the top of the rotating shaft 13 through a synchronous belt transmission mechanism 5, a stirring mechanism 14 is installed on the rotating shaft 13, and a screen 16 is installed in the lower body 10.

A number of stirring cone knives 20 are evenly distributed along the circumferential direction on the outer side of the stirring mounting cylinder 18. The stirring cone knives 20 are installed on the stirring mounting cylinder 18 at an angle through a connecting rod 19.

[0035] The stirring installation barrel 18 is installed on the rotating shaft 13 by a threaded connection. A gasket 15 is installed on the rotating shaft 13 below the stirring installation barrel 18. Wherein, the distance between the stirring mechanism 14 and the screen 16 in the lower body 10 can be quickly adjusted by the gasket 15.

[0036] The upper body mounting flange 8 at the bottom of the upper body 6 is installed together with the lower body mounting flange 9 at the top of the lower body 10; a screen top frame 17 is provided on the top outer side of the screen 16, and an upper card slot 21 for placing the screen top frame 17 is provided on the bottom inner side of the upper body mounting flange 8, an upper through hole 22 connected to the upper upper body 6 is provided on the upper body mounting flange 8 at the top of the upper card slot 21, a lower card slot 22 for placing the screen top frame 17 is provided on the top inner side of the lower body mounting flange 9, and a lower through hole 24 connected to the lower body 10 below is provided on the lower body mounting flange 9 at the bottom of the lower card slot 22.

[0038] Brief description of the working process of this utility model:

[0039] After the machine is started, the drug first enters the inclined conical feed port. The speed is adjusted by the control knob, and the actual parameters are displayed on the display. Simultaneously, the stirring cone blades on the rotating shaft stir the incoming drug, evenly dispersing it. They also squeeze the drug at the edges of the machine body, forcing it to pass through the screen and form smaller particles. These particles are then discharged from the lower discharge port, completing the granulation process. Adjusting the rotating shaft speed with the control knob changes the granulation speed of the product within the cavity.

[0040] This machine has a simple structure and a small footprint, making it suitable for benchtop operation in labs and pre-production environments. The unit consists of a detachable upper and lower body, allowing for quick installation and removal of the stirring mechanism and screen, making it easy to operate.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0042] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
