Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a granulation machine for granulated drugs. Background Technology

[0002] With the continuous development of science and technology, people's medical level is also improving. For various intractable diseases, they can be directly treated with drugs. Modern drug manufacturing technology has the ability to extract some effective ingredients better, making the drugs more effective. In terms of drug absorption, the shape of the drug capsule can ensure better absorption. The capsule usually contains drug particles to facilitate absorption.

[0003] In the current process of extruding and granulating drugs, some smaller dust particles are inevitably present. A secondary process is required to separate the powder from the granules. The resulting granules are not stable enough, and the secondary separation can cause the granules to be collided and squeezed again, resulting in an increase in the amount of powder formed.

[0004] This disclosure relates to a granulation machine for pharmaceuticals. The machine frame is designed with an inclined structure to facilitate the discharge of granules. The feed inlet of the feeding component is filtered, and then the feeding component rotates with the rotating component. The extrusion component extrudes the powder, allowing the powder to be squeezed out of the rotating component. The separation component separates the powder from the rotating component to form granules. After passing through the filtration component, the smaller powder particles are separated, achieving the direct separation of granules and powder.

[0005] In a first aspect, this disclosure provides a granulation machine for granulated drugs, specifically comprising: a machine frame; a rotating assembly rotatably mounted inside the machine frame, a feeding assembly mounted at the upper end of the rotating assembly, an extrusion assembly disposed inside the rotating assembly at the bottom of the feeding assembly, the bottom of the extrusion assembly being fixed to the bottom of the machine frame, a filtering assembly disposed on the upper outer side of the rotating assembly, the filter frame of the filtering assembly being disposed at the chamfered position at the upper end of the rotating assembly, the filter frame being configured as a mesh frame, a brush plate mounted at the bottom of the separation plate of the separation assembly at the position of the filter frame, an auxiliary assembly mounted at the machine frame position at the bottom of the filtering assembly, a discharge plate mounted on the right side of the machine frame corresponding to the filtering assembly, a separation assembly mounted at the discharge plate of the machine frame, the end of the separation assembly contacting the upper outer wall of the rotating assembly.

[0006] In at least some embodiments, the feed hopper of the feeding assembly is configured as a funnel-shaped structure, and a top filter frame is snapped into place inside the feed hopper. The top filter frame is configured as a mesh frame structure.

[0007] In at least some embodiments, the rotating frame of the rotating assembly is rotatably mounted on the machine frame, and a drive motor is installed on one side of the bottom of the rotating frame, with the drive motor meshing with the bottom of the rotating frame.

[0008] In at least some embodiments, the top corners of the rotating frame are chamfered, a connecting cylinder is provided at the top of the rotating frame, the bottom of the connecting cylinder is cylindrical, and a discharge hole is provided on the bottom outer wall of the connecting cylinder.

[0009] In at least some embodiments, the fixed shaft of the extrusion assembly is fixed at the bottom of the machine frame, and an extrusion block is provided at the top of the fixed shaft. The extrusion block is placed inside the connecting cylinder of the rotating assembly, and the extrusion block is configured as a volute block structure.

[0010] In at least some embodiments, the outer frame of the separation component is fixed to the outer wall of the machine frame near the unloading plate, a separation plate is hinged on the outer frame, the end of the separation plate contacts the conical outer wall of the connecting cylinder of the rotating component, and a connecting rod is installed between the separation plate and the outer frame.

[0011] In at least some embodiments, the auxiliary frame of the auxiliary component is disposed at the bottom of the filter component inside the machine frame, the auxiliary frame is inclined, and a discharge plate is disposed at the outer end of the bottom position of the auxiliary frame.

[0012] This utility model provides a granulation machine for granulated drugs, which has the following beneficial effects:

[0013] In this invention, the entire frame is tilted to allow the granules to be discharged more easily from the feed plate. The powder is poured in from the feeding component, which filters the powder and then contacts the extrusion component inside the rotating component. The extrusion component extrudes the powder from the discharge hole. At this time, the separation component peels the extruded powder from the discharge hole, and the resulting granules fall onto the filtering component. The filtering component separates the granules from some powder, allowing the powder to be discharged from the auxiliary component, while the granules are discharged directly through the feed plate, thus achieving the separation and discharge of granules and powder.

[0014] In addition, the rotating component is set as the main moving part of the device, while the extrusion component is fixed. The rotating frame is set to be rotated, so that when the drive motor drives the rotating frame, the rotating component rotates as a whole. This facilitates the subsequent extrusion and granulation of the medicine powder within the rotating component. First, the top edge of the rotating frame is set as a chamfered structure, allowing the medicine granules to slide outward better through the chamfered structure. The bottom of the connecting cylinder is set as a cone shape, which provides greater stability when the medicine powder is granulated through the discharge hole.

[0015] In addition, after the powder enters the extrusion block position inside the connecting cylinder, the extrusion assembly is fixed to the machine frame by a fixed shaft, while the rotating assembly rotates. At this time, the powder is squeezed against the inner wall of the connecting cylinder by the volute structure of the extrusion block, so that the powder is discharged from the discharge hole, thus achieving the granulation effect of the powder.

[0016] In addition, the end of the separator plate is set to be tightly attached to the outer wall of the connecting cylinder, so that the rotating connecting cylinder contacts the end of the separator plate, so that the drug particles extending from the discharge hole are separated by the separator plate, thus completing the granulation of the drug powder. A connecting rod is added between the outer frame and the separator plate to allow the separator plate to fit more tightly to the outer wall of the connecting cylinder for use.

[0017] In addition, after the granules pass through the beveled corner of the rotating component and face the filter frame, the mesh structure of the filter frame will filter them, allowing the filter frame to separate the granules from some of the powder. The brush plate set at the separation component allows the granules in the filter frame to be better discharged from the feed plate. An auxiliary frame is set at the bottom of the filter component. The inclined auxiliary frame can guide the powder to be discharged. The discharge plate at the bottom of the auxiliary frame is convenient for external tools to collect. Attached Figure Description

After the drug particles pass through the beveled corner of the rotating component 3 and are directed toward the filter frame 601, the mesh structure of the filter frame 601 will filter them, allowing the filter frame 601 to separate the drug particles from some of the powder. The brush plate 602 provided at the separation component 5 allows the drug particles in the filter frame 601 to be better discharged from the feed plate 8. An auxiliary component 7 is installed at the bottom of the machine frame 1. The feed plate 8 is installed on the right side of the machine frame 1 corresponding to the filter component 6. The separation component 5 is installed at the feed plate 8 of the machine frame 1. The end of the separation component 5 contacts the upper outer wall of the rotating component 3.

[0039] In this embodiment of the disclosure, such as Figure 3 Figure 4 As shown, the feed hopper 201 of the feeding assembly 2 is configured as a funnel-shaped structure. A top filter frame 202 is snapped into the inside of the feed hopper 201. The top filter frame 202 is configured as a mesh frame structure. The funnel shape of the feed hopper 201 allows the feed hopper 201 to better consolidate the powder when it is poured in. The top filter frame 202 installed inside the feed hopper 201 allows the mesh frame structure of the top filter frame 202 to filter out some impurities, which facilitates better granulation of the powder in the subsequent process.

[0040] In this embodiment of the disclosure, such as Figure 3 As shown, the rotating frame 301 of the rotating assembly 3 is rotatably mounted on the machine frame 1. A drive motor 303 is installed on one side of the bottom of the rotating frame 301. The drive motor 303 meshes with the bottom of the rotating frame 301. The rotating assembly 3 is set as the main moving part of the device, while the extrusion assembly 4 is fixed. The rotating frame 301 is set to be rotatably mounted so that when the drive motor 303 drives the rotating frame 301, the rotating assembly 3 rotates as a whole, which facilitates the subsequent extrusion and granulation of the medicine powder in the rotating assembly 3 through the extrusion assembly 4.

[0041] In this embodiment of the disclosure, such as Figure 6As shown, the top corners of the rotating frame 301 are chamfered, and a connecting cylinder 302 is provided at the top of the rotating frame 301. The bottom of the connecting cylinder 302 is cylindrical, and a discharge hole 304 is provided on the outer wall of the bottom of the connecting cylinder 302. First, the top edge of the rotating frame 301 is chamfered so that the top of the rotating frame 301 can slide the granules outward better through the chamfered structure. The bottom of the connecting cylinder 302 is conical so that the bottom of the connecting cylinder 302 has a more stable effect when granulating the powder through the discharge hole 304.

[0042] In this embodiment of the disclosure, such as Figure 4 As shown, the fixed shaft 401 of the extrusion assembly 4 is fixed at the bottom of the machine frame 1. An extrusion block 402 is provided on the top of the fixed shaft 401. The extrusion block 402 is placed inside the connecting cylinder 302 of the rotating assembly 3. The extrusion block 402 is set as a volute block structure. After the powder enters the position of the extrusion block 402 inside the connecting cylinder 302, the extrusion assembly 4 is fixed on the machine frame 1 by the fixed shaft 401. The rotating assembly 3 will rotate. At this time, the powder will be extruded by the volute structure of the extrusion block 402 onto the inner wall of the connecting cylinder 302, so that the powder can be discharged from the discharge hole 304, thus achieving the granulation effect of the powder.

[0043] In this embodiment of the disclosure, such as Figure 5 As shown, the outer frame 501 of the separation component 5 is fixed to the outer wall of the machine frame 1 near the feeding plate 8. A separation plate 502 is hinged on the outer frame 501. The end of the separation plate 502 contacts the conical outer wall of the connecting cylinder 302 of the rotating component 3. A connecting rod 503 is installed between the separation plate 502 and the outer frame 501. The end of the separation plate 502 is set to be tightly attached to the outer wall of the connecting cylinder 302, so that the rotating connecting cylinder 302 contacts the end of the separation plate 502. This allows the drug particles extending from the discharge hole 304 to be separated by the separation plate 502, thus completing the granulation of the drug powder. The connecting rod 503 installed between the outer frame 501 and the separation plate 502 allows the separation plate 502 to better fit the outer wall of the connecting cylinder 302 for use.

[0044] In this embodiment of the disclosure, such as Figure 2 As shown, the auxiliary frame 701 of the auxiliary component 7 is set at the bottom of the filter component 6 inside the machine frame 1.

The discharge plate 702 at the bottom of the auxiliary frame 701 is convenient for external tools to collect.

[0045] The working principle of this embodiment is as follows: When in use, the medicine powder is poured directly into the feeding component 2, and then the medicine powder falls into the rotating component 3 at the bottom of the feeding component 2, so that the medicine powder comes into contact with the extrusion component 4. The rotating component 3 will cause the medicine powder to be squeezed out from the discharge hole 304 through the extrusion component 4. At this time, the separation component 5 is closely attached to the outer end of the discharge hole 304. The rotating component 3 will cause the separation component 5 to peel off the protruding medicine powder, so that the medicine powder forms medicine particles. The medicine particles will slide to the filter component 6. The filter component 6 will filter the medicine particles and separate the medicine particles from some of the powder. The powder will be discharged from the auxiliary component 7, while the medicine particles will be discharged through the feed plate 8.
