Description

Technical Field

[0001] This utility model relates to the field of solid dosage form granulation technology, specifically to a continuous solid dosage form granulation device. Background Technology

[0002] Continuous solid dosage form granulation equipment is a key piece of equipment in the pharmaceutical industry used to convert powdered materials into granules. Its core function is to achieve continuous granulation through a continuous process, thereby improving production efficiency. Generally, granulation is completed by humidifying the powdered material, extruding it through contact with a plug, and allowing it to fall naturally.

[0003] In actual use, if the powder material is too wet, the particles that do not fall off in time may stick together, resulting in overly long particles that do not reach the desired length. At the same time, some of the extruded material may also stick to the outside of the plug hole, requiring manual cleaning over long-term use. Summary of the Invention

[0004] This utility model provides a continuous solid dosage form granulation equipment, which can drive a scraper ring to move up and down reciprocally through a drive mechanism to push off granules that have not fallen off in time, and at the same time remove material adhering to the outside of the granulation barrel.

[0005] To achieve the above objectives, a continuous solid dosage form granulation device is provided, comprising a placement base, a granulation barrel fixedly connected to the inner side of the upper end of the placement base, and a plurality of holes evenly distributed in a ring at equal angles on the outer side of the granulation barrel. A grinding blade is rotatably connected to the center of the inner bottom surface of the granulation barrel, and the grinding blade contacts the inner side of the granulation barrel. A grinding motor is fixedly installed on the inner bottom surface of the placement base, and the output end of the grinding motor passes through the granulation barrel and is fixedly connected to the center of the grinding blade. A scraper ring is slidably connected to the outer side of the granulation barrel, and a drive mechanism is fixedly connected to one side of the placement base. The drive mechanism is fixedly connected to the scraper ring. By setting the interaction between the drive mechanism and the scraper ring, the drive mechanism drives the scraper ring to move up and down reciprocally. While the scraper ring is moving up and down reciprocally, it pushes down the strip-shaped granules squeezed out by the grinding blade, and removes the material adhering to the outer side of the granulation barrel at the same time.

[0006] According to the continuous solid dosage form granulation equipment, the driving mechanism includes a connecting plate, a fixed plate, a connecting column, a mounting plate, a sliding column, a moving rod, a driving plate, a sliding groove, a driving motor, and a driving disk. The connecting plate is slidably connected to the outer side of the middle end of the placement seat. The mounting plate is fixedly connected to both sides of the scraper ring. The connecting column is fixedly connected to the end of the mounting plate away from the scraper ring, and the lower end of the connecting column is fixedly connected to the upper surface of the connecting plate. The moving connecting plate causes force to be applied to the connecting column and the mounting plate, which in turn causes the scraper ring to move up and down.

[0007] According to the continuous solid dosage form granulation equipment, the fixed plate is fixedly connected to the upper outer side of the placement seat, and the moving rod is fixedly connected to the upper surface of the connecting plate away from the center. The upper end of the moving rod passes through the fixed plate and extends above the fixed plate. By setting the mutual cooperation between the moving rod and the fixed plate, the moving rod is limited, preventing the connecting plate from driving the moving rod to move.

[0008] According to the continuous solid dosage form granulation equipment, the moving rod is rectangular in shape, and the contact surface between the moving rod and the fixed plate is smooth. By making the contact surface between the moving rod and the fixed plate smooth, friction is reduced, making the movement of the moving rod more stable.

[0009] According to the continuous solid dosage form granulation equipment described above, the drive plate is fixedly connected to the upper end of the moving rod, the sliding groove is formed on the surface of the drive plate, the sliding column slides inside the sliding groove, the drive motor is fixedly installed on the top surface of the fixed plate, the drive disk is fixedly connected to the output end of the drive motor, and the sliding column is fixedly connected to the side of the drive disk away from the center. The rotation of the drive disk drives the sliding column to rotate simultaneously. As the sliding column slides inside the sliding groove, the drive plate is subjected to force, which in turn drives the moving rod to move up and down.

[0010] According to the continuous solid dosage form granulation equipment described above, a protective shell is fitted around the drive motor, and the protective shell is fixedly connected to the upper surface of the fixing plate. The protective shell protects the drive motor, preventing foreign objects from directly contacting and damaging it.

[0011] According to the continuous solid dosage form granulation equipment described above, the inner sides of the sliding column and the sliding groove are mutually engaged, and the contact surfaces of the sliding column and the sliding groove are set to be smooth. By setting the sliding column and the sliding groove to engage, the sliding column drives the sliding groove to bear force, thereby making the reaction faster.

[0012] According to the continuous solid dosage form granulation equipment described above, a collecting tray is provided above the fixed plate. The collecting tray is fixedly connected to the outer surface of the placement seat, and a guide block is fixedly connected to one side of the collecting tray. The guide block is fixedly connected to the inner side of the collecting tray. By setting up the collecting tray, falling materials can be collected.

[0013] The beneficial effects of this utility model are as follows: by setting up the cooperation between the drive mechanism and the scraper ring, the drive mechanism drives the scraper ring to move up and down reciprocally. While the scraper ring moves up and down reciprocally, it pushes down the granules squeezed out by the crushing blade. At the same time, the material adhering to the outside of the granulation barrel is removed, so that manual scraping and cleaning are not required, saving time and effort.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The connecting column 2203 is fixedly connected to the end of the mounting plate 2204 away from the scraper ring 8. The lower end of the connecting column 2203 is fixedly connected to the upper surface of the connecting plate 2201.

[0026] The fixed plate 2202 is fixedly connected to the upper outer side of the placement base 1, and the moving rod 2206 is fixedly connected to the upper surface of the connecting plate 2201 away from the center. The upper end of the moving rod 2206 passes through the fixed plate 2202 and extends to the top of the fixed plate 2202. The moving rod 2206 is rectangular, and the contact surface between the moving rod 2206 and the fixed plate 2202 is smooth.

[0027] The drive plate 2207 is fixedly connected to the upper end of the moving rod 2206. The sliding groove 2208 is formed on the surface of the drive plate 2207.

[0028] Working principle: In use, the powder material to be granulated is first moistened and mixed with a binder or wetting agent. Then, the grinding motor 4 is started, causing the grinding blades 3 to rotate. As the grinding blades 3 rotate, the mixed powder material is poured into the inner side of the granulation drum 2. The rotating grinding blades 3, in contact with the granulation drum 2, compress the powder material, causing it to protrude through the holes on the surface of the granulation drum 2. Most of the material falls to the inner side of the collection tray 7 under gravity, while a small portion that doesn't fall immediately adheres to the surface of the granulation drum 2 and the outer side of the holes. At this point, the drive motor 2209 is started, causing the drive disc 2210 to rotate. When the disc 2210 rotates, it drives the sliding column 2205 to rotate simultaneously, causing the sliding column 2205 to slide inside the sliding groove 2208. During the sliding, the drive plate 2207 is subjected to force, which in turn drives the moving rod 2206 to move up and down. Since the moving rod 2206 is fixed to the connecting disc 2201, it also drives the connecting disc 2201 to move up and down. When the connecting disc 2201 moves, through the fixed cooperation with the connecting column 2203 and the mounting plate 2204, it drives the scraper ring 8 to move up and down, thereby pushing down the material particles that have not fallen in time and the adhering material. After granulation is completed, the container is placed at the guide block 5 to collect the material inside the collection disc 7.
