Description

Technical Field

[0001] This application relates to the technical field of pharmaceutical equipment, and in particular to a gyratory pellet mill. Background Technology

[0002] In the pharmaceutical industry, the oscillating granulator uses the repeated oscillation of a rotating drum to force the medicine through arc-shaped screens of different diameters, thereby pressing moist powder or dry loose material into granules of different sizes. These granules are used as intermediate particles in the manufacture of granules or tablets, and granule preparation is one of the important steps in the pharmaceutical process.

[0003] In the existing pellet mill production process, the operator places a collection box below the discharge port of the device to collect the material. In order to achieve quantitative pellet filling, manual monitoring is usually adopted. The operator needs to pay attention to the material feeding of the device at all times and replace the collection box in time when it is full.

[0004] Regarding the aforementioned technologies, manual monitoring and replacement of the collection box is prone to errors due to fatigue or negligence, leading to particle overflow and waste. During the particle production process, operators are unable to perform other tasks, resulting in wasted labor costs and increased labor costs. Utility Model Content

[0005] To reduce labor costs, this application provides a gyratory pellet mill.

[0006] This application provides a gyratory pellet mill, which adopts the following technical solution:

[0007] A vibrating pellet mill, comprising:

[0008] The machine casing is provided with a material inlet;

[0009] A granulation assembly is disposed inside the machine housing and installed below the feed inlet. The granulation assembly is used to granulate the drug.

[0010] A drive box is fixedly connected to the chassis, and a drive system is installed inside the drive box. The drive system is used to drive the granulation assembly to operate.

[0011] A feeding pipe, one end of which is fixedly installed at the bottom of the machine housing, and the feeding pipe is connected to the machine housing;

[0012] A collection box is disposed at the bottom of the discharge pipe;

[0013] A pipe switch assembly is installed on the feed pipe and is used to control the opening and closing of the feed pipe.

[0014] A control unit is installed at the bottom of the collection box and is used to control the operation of the pipeline switch assembly;

[0015] A warning device is installed on the drive box and is used to detect the filling status of the collection box and emit visual and audible signals.

[0016] By adopting the above technical solution, during granulation, the drug is added through the inlet. Driven by the drive system, the granulation assembly forms the drug into granules. The finished granules flow out from the feed pipe and fall into the collection box. Under the control of the control components, the pipe switch assembly on the feed pipe automatically adjusts its working state according to the actual situation. The warning device monitors the material level in the collection box and promptly issues visual and audible signals to remind the operator to take measures and quickly replace the collection box. This granulator significantly reduces the labor costs in granule drug preparation and improves the automation level of the granule drug preparation process.

[0017] Optionally, the granulation assembly includes:

[0018] A rotating disk is rotatably mounted on the chassis, and the drive system drives the rotating disk to rotate.

[0019] A rotating shaft is coaxially and fixedly mounted on the rotating disk, and a spline is provided on the rotating shaft;

[0020] A rotating drum is slidably mounted on the rotating shaft, and the sliding direction is consistent with the axial direction of the rotating shaft;

[0021] A screen, both ends of which are fixedly mounted on the machine housing, is wound around the rotating drum.

[0022] By adopting the above technical solution, the medicine enters the granulation component through the feed port. The drive system drives the rotating disk to rotate back and forth, which in turn drives the rotating shaft to rotate. Under the action of the spline on the rotating shaft, the rotating drum rotates back and forth. During the rotation, the rotating drum will fully tumble and stir the raw materials in the machine box. At the same time, the raw materials will be continuously squeezed against the screen. Through the forming action of the screen, granules are finally formed. The granulation component can realize a stable granulation process.

[0023] Optionally, the pipeline switching assembly includes:

[0024] The mounting box is fixedly mounted on the feed pipe;

[0025] The first telescopic rod, the fixed end of the first telescopic rod is fixedly installed on the mounting box;

[0026] A first spring is disposed within the rodless cavity of the first telescopic rod;

[0027] A sliding plate, which is fixedly installed at the movable end of the first telescopic rod, and has a sliding groove on it;

[0028] A rotating rod is mounted on the feeding pipe, with one end of the rotating rod extending out of the feeding pipe and into the mounting box;

[0029] A sealing disc, which is fixedly installed on the rotating rod, and the size of the sealing disc is adapted to the size of the feed pipe;

[0030] A rotating block is disposed inside the mounting box and is fixedly mounted on the rotating rod;

[0031] The slider is hinged to the rotating block and is slidably installed in the groove, with the sliding direction perpendicular to the extension and retraction direction of the first telescopic rod.

[0032] By adopting the above technical solution, the combination of the first telescopic rod and the first spring allows the slide plate to move freely within a certain range, thereby driving the movement of the rotating block and the slider. When it is necessary to close the feeding pipe, the rotating rod drives the sealing disc to rotate, so that the periphery of the sealing disc fits tightly with the feeding pipe to achieve sealing. When it is necessary to open the feeding pipe, the opposite action process creates a gap between the sealing disc and the feeding pipe, enabling feeding. The automatic opening and closing function of the feeding pipe is realized through the pipeline switch assembly, avoiding the overflow and waste of particles.

[0033] Optionally, the control element includes:

[0034] A control box, which is fixedly mounted on the chassis, has an opening at the top and is located at the bottom of the collection box;

[0035] A movable plate is slidably installed inside the control box, with the sliding direction along the axis of the feed pipe, and the collection box is placed on the movable plate;

[0036] The second telescopic rod is installed inside the control box, and its two ends are fixedly connected to the movable plate and the bottom of the control box, respectively.

[0037] The second spring is mounted on the second telescopic rod, and both ends of the second spring are fixedly connected to the movable plate and the fixed end of the second telescopic rod, respectively.

[0038] A venting tube, one end of which is connected to the rod-side cavity of the first telescopic rod, and the other end of which is connected to the rodless cavity of the second telescopic rod.

[0039] By adopting the above technical solution, during the granulation process, when the granular drug in the collection box reaches a certain weight, the movable plate moves downward due to gravity, compressing the second telescopic rod and the second spring, thereby triggering the control component and controlling the pipeline switch assembly to close the feed pipe, thus automatically stopping the feeding. This design effectively reduces the workload of operators, realizes automatic detection of changes in the weight of the collection box, avoids fatigue caused by continuous monitoring, and ensures consistent weight of granular drug in the collection box by precisely controlling the feeding amount.

[0040] Optionally, the warning device includes:

[0041] A touch switch, which is fixedly installed on the inner side wall of the control box;

[0042] Warning light, which is fixedly mounted on the drive box and electrically connected to the touch switch;

[0043] A buzzer is fixedly mounted on the drive box and is electrically connected to the touch switch.

[0044] By adopting the above technical solution, when the granular medicine entering the collection box is about to reach the capacity of the collection box, or when the amount of granules in the collection box reaches a certain amount, the touch switch is triggered, the warning light lights up and the buzzer sounds, thereby reminding the operator to replace the collection box in time, avoiding granule overflow or waste, and improving the ease of use of the pellet mill.

[0045] Optionally, the chassis is provided with an observation window, which is made of transparent material.

[0046] By adopting the above technical solution, the transparent observation window allows operators to intuitively monitor the granulation process inside the machine, improving the visibility of the production process, facilitating timely detection and handling of problems, and reducing equipment failures or product quality issues caused by the inability to observe in real time.

[0047] Optionally, the chassis has an installation port on the side away from the drive box, and a cover plate is provided on the installation port. The cover plate is threaded to the chassis, and one end of the rotating roller is rotatably mounted on the cover plate.

[0048] By adopting the above technical solution, the installation port on the side of the chassis away from the drive box and the matching cover plate structure provide a convenient passage for the installation of the rotating drum, making equipment maintenance more convenient. During the use of the pellet mill, the rotating drum may need to be replaced due to wear and tear from long-term operation. The cover plate allows the rotating drum to be replaced or repaired without disassembling the entire chassis, improving the maintainability and ease of operation of the equipment.

[0049] Optionally, the inlet is narrowed so that all the poured medicine passes through the rotating drum.

[0050] By adopting the above technical solution, the constricted inlet ensures that all the poured medicine passes through the rotating drum, avoiding medicine scattering or insufficient processing, and improving the uniformity and efficiency of granule preparation.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. By setting up pipeline switch components and control devices, automatic quantitative dispensing of granules is achieved, reducing the need for manual monitoring and lowering labor costs and labor intensity;

[0053] 2. The amount of particles in the collection box is detected by the control components, and the opening and closing of the feed pipe is controlled by the pipeline switch assembly, which effectively avoids particle overflow and waste caused by human monitoring errors, and improves production efficiency and product quality.

[0054] 3. The warning device can emit visual and audible signals when the collection box is close to full, reminding operators to replace the collection box in time, reducing misoperation caused by negligence or fatigue, and improving production safety. Attached Figure Description

[0064] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0065] This application discloses a gyratory pellet mill.

[0066] Reference Figure 1 and Figure 2The oscillating granulator includes a casing 1, a granulation component 2, a drive box 3, a feed pipe 4, a collection box 5, a pipe switch assembly 6, a control component 7, and a warning component 8. The casing 1 has a feed inlet 11. The granulation component 2 is located inside the casing 1 and installed below the feed inlet 11. The granulation component 2 is used to granulate the medicine. The drive box 3 is fixedly connected to the casing 1 and contains a drive system used to drive the granulation component 2. One end of the feed pipe 4 is fixedly installed at the bottom of the casing 1, and the feed pipe 4 communicates with the casing 1. The collection box 5 is located at the bottom of the feed pipe 4. The pipe switch assembly 6 is installed on the feed pipe 4 and is used to control the opening and closing of the feed pipe 4. The control component 7 is installed at the bottom of the collection box 5 and is used to control the operation of the pipe switch assembly 6. The warning component 8 is installed on the mounting box 61 and is used to detect the filling status of the collection box 5 and emit visual and audible signals.

[0067] When in use, start the drive system in the drive box 3. The drive system drives the granulation component 2 to start running. Then, the raw material to be granulated is put into the machine box 1 through the feed port 11 on the machine box 1 and falls into the granulation component 2. The granulation component 2 processes the raw material to make it into granules that meet the requirements. The granules are then slid down through the feed pipe 4 connected to the bottom of the machine box 1 and enter the collection box 5 below for collection.

[0068] During the collection process, the control unit 7 installed at the bottom of the collection box 5 monitors the filling status of the collection box 5 in real time. When the set full state is reached, the control unit 7 controls the pipe switch assembly 6 to close the feed pipe 4, stopping the particles from falling into the collection box 5 and preventing particle overflow. At the same time, the warning unit 8 installed on the machine box 1 will emit visual and audible signals when it detects that the collection box 5 is about to be full, reminding the operator to replace the collection box 5 in time. After the collection box 5 is replaced, the control unit 7 controls the pipe switch assembly 6 to open the feed pipe 4 and continue to collect particles. This cycle ensures that the particle collection work is carried out in an orderly manner, realizes the continuous and stable granulation and collection operation of the swing pellet mill, and reduces the cost of manual monitoring.

[0069] Reference Figure 1 and Figure 2 The casing 1 has a rectangular box structure with an opening at the top. The feed inlet 11 on the casing 1 is narrowed, so that all the poured medicine passes through the granulation component 2. The side wall of the casing 1 is also equipped with an observation window 9, which is made of transparent material, so that the operator can intuitively monitor the granulation process inside the casing 1.

[0070] Reference Figure 2 and Figure 4The granulation assembly 2 includes a rotating disk 21, a rotating shaft 22, a rotating drum 23, and a screen 24. The rotating disk 21 is rotatably mounted on the housing 1 and is located on the side of the housing 1 near the drive box 3. The drive system drives the rotating disk 21 to rotate. The drive system in the oscillating granule can be a motor driven by a belt, chain, or direct gear, etc., and this application does not make a specific limitation. The rotating shaft 22 is coaxially fixedly mounted on the rotating disk 21 and is provided with a spline. The rotating drum 23 is horizontally arranged, and one end of the rotating drum 23 is slidably mounted on the rotating shaft 22. The sliding direction is along the axial direction of the rotating shaft 22. The spline is engaged with the rotating drum 23. Both ends of the screen 24 are fixedly mounted on the housing 1 and the screen 24 is wound around the rotating drum 23.

[0071] When in use, after the drive system is started, the power is transmitted to the rotating disk 21, causing the rotating disk 21 to start to rotate back and forth. The rotation of the rotating disk 21 drives the rotating shaft 22 to rotate synchronously. The spline set on the rotating shaft 22 cooperates with the rotating drum 23 installed on it. When the rotating shaft 22 rotates, the spline drives the rotating drum 23 to rotate back and forth around the shaft. At the same time, the raw materials of medicine put in from the feed port 11 of the machine box 1 enter the interior of the rotating drum 23.

[0072] As the rotating drum 23 rotates, the pharmaceutical raw materials inside are fully turned over, stirred and gradually squeezed towards the screen 24. When the raw materials are squeezed to the screen 24, under the continuous action of the rotating drum 23, the pharmaceutical raw materials are squeezed into granules and fall through the screen 24, thereby realizing the granulation process of pharmaceutical raw materials and obtaining uniform pharmaceutical granule products.

[0073] Reference Figure 2 and Figure 3 The pipeline switch assembly 6 includes a mounting box 61, a first telescopic rod 62, a first spring 63, a sliding plate 64, a rotating rod 65, a sealing disc 66, a rotating block 67, and a slider 68. Mounting box 61 is fixedly mounted on feeding pipe 4. First telescopic rod 62 is vertically mounted inside mounting box 61. Fixed end of first telescopic rod 62 is fixedly mounted on mounting box 61. First spring 63 is located in rodless cavity of first telescopic rod 62. Slide plate 64 is fixedly mounted on movable end of first telescopic rod 62. Slide plate 64 has a sliding groove, which is L-shaped. Rotating rod 65 passes through feeding pipe 4. One end of rotating rod 65 passes through feeding pipe 4 and into sliding groove. Sealing plate 66 is disc-shaped and fixedly mounted on rotating rod 65. Sealing plate 66 is adapted to the size of feeding pipe 4. Rotating block 67 is located inside mounting box 61 and fixedly mounted on rotating rod 65. Sliding block 68 is hinged to rotating block 67 and slidably mounted in sliding groove. Sliding direction is perpendicular to telescopic direction of first telescopic rod 62.

[0074] Reference Figure 2 and Figure 4 The control component 7 includes a control box 71, a movable plate 72, a second telescopic rod 73, a second spring 74, and a vent pipe 75. The control box 71 is located at the bottom of the collection box 5, and is fixedly mounted on the machine housing 1 with an open top. The movable plate 72 is slidably mounted inside the control box 71, with the sliding direction along the axis of the feed pipe 4. The periphery of the sliding plate abuts against the control box 71. The collection box 5 is placed on the movable plate 72. The second telescopic rod 73 is vertically mounted inside the control box 71, and its two ends are fixedly connected to the bottom of the movable plate 72 and the control box 71, respectively. The second spring 74 is mounted on the second telescopic rod 73, and its two ends are fixedly connected to the fixed ends of the movable plate 72 and the second telescopic rod 73, respectively. One end of the vent pipe 75 is connected to the rod-side cavity of the first telescopic rod 62, and the other end of the vent pipe 75 is connected to the rodless cavity of the second telescopic rod 73.

[0075] When the oscillating granulator starts running, the collection box 5 is empty. Under the action of the second spring 74, the second telescopic rod 73 is in the extended state, so that the movable plate 72 is in a higher position inside the control box 71. At the same time, the sealing plate 66 opens the feed pipe 4, and the granular medicine can fall smoothly into the collection box 5.

[0076] As particles continuously fall into the collection box 5, the weight of the collection box 5 gradually increases, exerting downward pressure on the movable plate 72. When the pressure reaches a certain level, the movable plate 72 overcomes the elastic force of the second spring 74 and begins to slide downward, causing the second telescopic rod 73 to retract. When the second telescopic rod 73 retracts, the volume of its rodless cavity decreases, and the internal gas is forced into the rod cavity of the first telescopic rod 62 through the vent pipe 75, increasing the pressure inside the rod cavity of the first telescopic rod 62, which then overcomes the elastic force of the first spring 63 and begins to retract. The retraction of the first telescopic rod 62 causes the slide plate 64 to move downward, and the slider 68 slides along the L-shaped horizontal section of the chute. The slider 68 pulls the rotating block 67 to rotate, which in turn drives the sealing disc 66 to rotate, gradually reducing the flow area of ​​the discharge pipe 4.

[0077] When the material in the collection box 5 reaches the preset near-full state, the movable plate 72 slides down to the lowest position, causing the first telescopic rod 62 to retract sufficiently to completely block the discharge pipe 4 with the sealing plate 66, at which point the particles stop falling.

[0078] When the collection box 5 is replaced, the pressure on the movable plate 72 disappears. Under the elastic force of the second spring 74, the movable plate 72 moves upward, the second telescopic rod 73 extends, the pressure in its rodless chamber decreases, the gas in the rod chamber of the first telescopic rod 62 flows back, the first spring 63 pushes the first telescopic rod 62 to extend again, driving the slide plate 64 to move upward, the slider 68 slides, the rotating rod 65 drives the sealing plate 66 to reopen the feed pipe 4, and the collection of particles resumes. This cycle repeats, realizing the automatic control of the opening and closing of the feed pipe 4 according to the filling status of the collection box 5, and accurately completing the quantitative collection of particles.

[0079] Reference Figure 2 The warning device 8 includes a touch switch 81, a warning light 82, and a buzzer 83. The touch switch 81 is fixedly installed on the inner side wall of the control box 71, the warning light 82 is fixedly installed on the drive box 3 and is electrically connected to the touch switch 81, and the buzzer 83 is fixedly installed on the drive box 3 and is electrically connected to the touch switch 81.

[0080] During normal operation of the equipment, as the material in the collection box 5 gradually increases, the movable plate 72 gradually descends. When the movable plate 72 descends to the critical position where the collection box 5 is about to be full, it will touch the touch switch 81 installed on the inner side wall of the control box 71. After the touch switch 81 is triggered, the warning light 82 electrically connected to it immediately lights up, emitting a conspicuous visual signal on the drive box 3 so that the operator can quickly notice this change in the equipment's status. At the same time, the buzzer 83 connected to the touch switch 81 will also sound an audible alarm, attracting the operator's attention through auditory stimulation, so that the operator knows that the collection box 5 has reached the state requiring processing, and immediately replaces the collection box 5 with a new one, thereby effectively avoiding problems such as particle overflow caused by the collection box 5 being overfilled.

[0081] Reference Figure 2 The chassis 1 has an installation port on the side away from the drive box 3. A cover plate 12 is provided on the installation port. The cover plate 12 is threadedly connected to the chassis 1. One end of the rotating roller 23 is rotatably mounted on the cover plate 12.

[0082] When the rotating roller 23 needs maintenance or needs to be replaced due to malfunction or other reasons, the cover plate 12 is unscrewed from the housing 1. The operator can clearly see the rotating roller 23 and its surrounding components through the installation port. The operator can then reach into the housing 1 and remove the rotating roller 23 from the installation port, making the installation process of the rotating roller 23 smoother and more efficient, and reducing the installation difficulty and time cost.

[0083] The implementation principle of a swing granulator according to an embodiment of this application is as follows: the raw materials of medicine are fed into the machine box 1 through the feed port 11 of the machine box 1, the drive system drives the rotating disk 21 to rotate, the rotating disk 21 drives the rotating shaft 22 to rotate, and the spline on the rotating shaft 22 drives the slidably mounted rotating drum 23 to rotate, so that the raw materials are turned over and squeezed in the rotating drum 23, and after being screened by the screen 24 surrounding it, the particles that meet the particle size requirements fall off.

[0084] The produced granules enter the collection box 5 through the feed pipe 4 at the bottom of the machine casing 1. The control component 7 at the bottom of the collection box 5, based on the filling status, controls the rotation of the sealing disc 66 installed on the feed pipe 4 via the vent pipe 75 and the pipe switch assembly 6, thereby opening and closing the feed pipe 4 for precise quantitative collection. When the collection box 5 is nearly full, the touch switch 81 is triggered, the warning light 82 illuminates, and the buzzer 83 sounds, prompting the operator to handle the situation, ensuring stable equipment operation and orderly granule collection, and reducing labor costs.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
