Description

Technical Field

[0001] This utility model relates to the field of tablet pressing device technology, and in particular to a rotary tablet pressing device. Background Technology

[0002] In the pharmaceutical industry, tablets, as one of the important dosage forms of medicines, are widely used due to their convenience, accurate dosage, and high stability. The production of tablet medicines is usually completed using tableting equipment, among which rotary tablet presses have become the most widely used tableting equipment in pharmaceutical companies due to their advantages such as high efficiency, uniform tablet formation, and adaptability to mass production. The working process of a rotary tablet press mainly includes quantitative feeding of drug powder, compression molding within the mold cavity, and ejection and collection of finished tablets. Its core components typically consist of a drug storage mechanism, a feeding system, a rotary pressing mechanism, and a tablet ejection mechanism. With the increasing demands for automation and precision in pharmaceutical production, improving the accuracy of feeding and the continuity of the compression process while ensuring tablet forming accuracy has become a key direction for the improvement of existing rotary tablet presses.

[0003] In the prior art, Chinese patent document CN222875402U discloses a rotary tablet pressing device. This device includes a tablet press, a pressing assembly, and a control panel. The pressing assembly is connected to the upper part of the tablet press, and the control panel is connected to the upper left side of the tablet press. By starting a first motor, a lever rotates, causing a sliding screen to move back and forth on a guide rod. This allows unpressed tablet powder to fall through the holes in the sliding screen into a collection box engaged between lower guide rails, effectively sieving and collecting the tablet powder and preventing significant waste. However, similar to the prior art, the alignment between the loading hole and the pressing cylinder is not precise enough during the feeding process. Powder falls in prematurely before alignment, leading to powder leakage, material shortage, or uneven accumulation, resulting in poor practicality. Therefore, this utility model discloses a rotary tablet pressing device to solve the problems of powder leakage, material shortage, and unstable pressing in the prior art during tablet pressing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a rotary tablet pressing device to solve the problems of powder leakage, material shortage and unstable pressing in the existing tablet pressing process.

Each set of loading holes has a tablet pressing cylinder on its upper end. Limiting circular baffles are provided on the side of the tablet pressing cylinder near the central axis of the second mounting plate and on the side away from the central axis of the second mounting plate. Each set of tablet pressing cylinders has inclined slopes on both sides along the circumferential direction of the limiting circular baffles. A feeding structure is provided on the fixed frame. A second mounting platform is provided on the side wall of the operating worktable located on one side of the fixed frame. A pressing structure is provided on the second mounting platform.

[0007] Preferably, the feeding structure includes a first feeding tube, the top end of which is connected to the lower end of the connecting cylindrical tube, and a first fixing ring is provided on the lower outer wall of the first feeding tube. A connecting tube is slidably inserted into the bottom inner wall of the first feeding tube, and a second feeding tube is slidably inserted into the other end of the connecting tube. A second fixing ring is provided on the upper outer wall of the second feeding tube, and a vertical spring is sleeved on the first feeding tube, the connecting tube, and the second feeding tube between the first fixing ring and the second fixing ring. The bottom end of the second feeding tube slidably abuts against the upper end face of the tablet pressing cylinder.

[0008] Preferably, the pressing structure includes a pressing cylinder. One end of the pressing cylinder is fixedly mounted on the upper surface of the second mounting platform via a fixed cylinder. The output end of the pressing cylinder is connected to an output rod. The other end of the output rod passes through and protrudes from the outer wall of the second mounting platform and is fixedly mounted with a pressing ring. The other end of the pressing ring is on the same vertical central axis as the tablet pressing cylinder at the corresponding position. A first circular hole is opened on the second mounting platform corresponding to the position of the output rod. The output rod is slidably inserted vertically into the first circular hole. The outer diameter of the pressing ring matches the inner diameter of each set of tablet pressing cylinders.

[0009] Preferably, the upper end face of the first mounting circular plate is provided with an annular groove, and the lower end face of the second mounting circular plate is provided with an annular protrusion corresponding to the annular groove.

[0014] The beneficial effects of this utility model are: By setting up an operating table and a fixed frame on the loading base, and installing a controller and switching valve on the fixed frame, a complete feeding unit is formed by combining the medicine storage cylinder, feeding pipe, and connecting round pipe. A servo motor drives the output rotating shaft to rotate the second mounting round plate, allowing the powder to enter the feeding pipe sequentially and quantitatively under the controller's instructions and finally fall into the filling hole, ensuring the stability and controllability of the feeding process. Because the second feeding pipe can move upwards and compress the vertical spring under the action of the limiting baffle and inclined slide during rotation, it can maintain a tight fit with the tablet pressing cylinder throughout the alignment process. The filling hole and the tablet pressing cylinder achieve precise alignment when rotated into position, avoiding premature powder leakage and misalignment, thus improving the accuracy of feeding and the consistency of the tablets. In the pressing stage, the pressing cylinder drives the pressing ring to cooperate coaxially with the tablet pressing cylinder through the output rod, so that the powder receives stable and uniform pressure in the limited mold cavity, avoiding empty pressure or uneven pressure in cases of incomplete filling or misalignment, thereby ensuring the integrity and density of the tablet formation. Furthermore, the combination of the dispensing hole, dispensing ramp, and splash guard allows the pressed tablets to fall smoothly into the collection device, effectively preventing tablet splashing or accumulation and keeping the work surface clean. Overall, this invention achieves close coordination and cyclical connection between the three major stages of feeding, rotation, and pressing. It not only solves the problems of inaccurate feeding, unstable pressing, and powder waste in existing technologies, but also improves the durability and reliability of the equipment through the precise drive of the servo motor and the auxiliary effect of spring buffering, thereby significantly improving the stability and consistency of tablet production. It has high practical value and promotional significance. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] This utility model provides, for example Figures 1 to 4 The rotary tablet compression device shown includes: a fixed frame 3 on one side of a loading base 1, an operating table 2 on the top of the loading base 1, a controller 4 installed on one side of the top of the fixed frame 3, a switch valve 5 at the output end of the controller 4, and the controller 4 and the switch valve 5 connected by an electrical signal, a first mounting platform 9 on the top of the fixed frame 3 near the operating table 2, a drug storage cylinder 6 on the first mounting platform 9, a feeding pipe 7 on the top of the drug storage cylinder 6, a connecting round pipe at the bottom of the drug storage cylinder 6, the switch valve 5 installed on the connecting round pipe, and a rotary compression assembly on the operating table 2. The rotary compression assembly is used to compress the drug powder leaking from the drug storage cylinder 6 into tablets. By setting an operating workbench 2 and a fixed frame 3 on the loading base 1, and installing a controller 4 and a switching valve 5 on the fixed frame 3, a complete feeding unit is formed by combining the medicine storage cylinder 6, the feeding pipe 7, and the connecting round pipe. Then, the output rotating shaft 28 driven by the servo motor drives the rotation of the second mounting round plate 15, so that the medicine powder can enter the feeding pipe in sequence and quantitatively under the command of the controller 4 and finally fall into the filling hole 29, ensuring the stability and controllability of the feeding. Since the second feeding pipe 20 can move upward to compress the vertical spring 22 under the action of the limit baffle and the inclined slide 18 during the rotation, it can always be in close contact with the tablet pressing cylinder 17 during the alignment process. The filling hole 29 and the tablet pressing cylinder 17 achieve precise fit when rotated into place, avoiding the problems of premature leakage of medicine powder and misaligned filling, improving the accuracy of feeding and the consistency of tablets. In the pressing stage, the pressing cylinder 8, through the output rod 26, drives the pressing ring 27 to coaxially engage with the tablet pressing cylinder 17, ensuring that the powder is subjected to stable and uniform pressure within the defined mold cavity. This avoids air pressure or uneven pressure in cases of incomplete filling or misalignment, thus guaranteeing the integrity and density of the formed tablets. Furthermore, the combination of the dispensing hole 14, the dispensing ramp 10, and the splash guard 11 allows the pressed tablets to fall smoothly into the collection device, effectively preventing tablet splashing or accumulation and keeping the work surface clean. Overall, this invention achieves close coordination and cyclical connection between the three major stages of feeding, rotation, and pressing. It not only solves the problems of inaccurate feeding, unstable pressing, and powder waste in existing technologies, but also improves the durability and reliability of the equipment through the precise drive of the servo motor and the auxiliary effect of spring buffering, thereby significantly improving the stability and consistency of tablet production. It has high practical value and promotional significance.

[0021] Furthermore, in this example, such as Figure 2 , Figure 3 and Figure 4As shown, the rotary pressing assembly includes a first mounting circular plate 13. The bottom end of the first mounting circular plate 13 is fixedly mounted on the upper surface of the operating workbench 2 by multiple sets of fixing columns 12. A drug discharge ramp 10 is formed on the upper surface of the operating workbench 2 at the end away from the fixing frame 3. A splash guard 11 is installed on the operating workbench 2 at the edge of the drug discharge ramp 10. A drug discharge circular hole 14 is formed on the first mounting circular plate 13 at the same position as the drug discharge ramp 10 in the vertical direction. An output rotating shaft 28 is rotatably mounted in the middle of the first mounting circular plate 13. A servo motor is provided through the middle of the operating workbench 2 at the bottom end of the output rotating shaft 28. The servo motor is fixedly mounted in the inner cavity of the loading base 1, and the output of the servo motor... The first mounting plate 13 is fixedly connected to the output rotating shaft 28. The upper end face of the first mounting plate 13 is engaged and rotatably mounted with the second mounting plate 15. The bottom center of the second mounting plate 15 is fixedly mounted on one end of the output rotating shaft 28. The second mounting plate 15 has multiple assembly holes 29 arranged in a circumferential array corresponding to the position of the dispensing hole 14. The upper end face of each assembly hole 29 is provided with a tablet pressing cylinder 17. A limiting circular baffle 16 is provided on the side of the tablet pressing cylinder 17 near the central axis of the second mounting plate 15 and on the side away from the central axis of the second mounting plate 15. Each set of tablet pressing cylinders 17 has inclined slopes 18 on both sides along the circumferential direction of the limiting circular baffle 16. The fixing frame 3 is provided with a feeding structure. Furthermore, a second mounting platform 19 is provided on the side wall of the operating workbench 2, located on one side of the fixed frame 3. The second mounting platform 19 has a pressing structure. The feeding structure includes a first feeding pipe 24, the top end of which is connected to the lower end of a connecting round pipe. A first fixing ring 25 is provided on the lower outer wall of the first feeding pipe 24, and a connecting pipe 23 is slidably inserted into the bottom inner wall of the first feeding pipe 24. A second feeding pipe 20 is slidably inserted into the other end of the connecting pipe 23. A second fixing ring 21 is provided on the upper outer wall of the second feeding pipe 20. A vertical spring 22 is sleeved and installed on the first feeding pipe 24, the connecting pipe 23, and the second feeding pipe 20 between the first fixing ring 25 and the second fixing ring 21. The bottom end slides against the upper end face of the tablet pressing cylinder 17. The pressing structure includes a pressing cylinder 8. One end of the output end of the pressing cylinder 8 is fixedly installed on the upper end face of the second mounting platform 19 through a fixed cylinder. The output end of the pressing cylinder 8 is connected to an output rod 26. The other end of the output rod 26 passes through and protrudes from the outer wall of the second mounting platform 19 and is fixedly installed with a pressing ring 27. The other end of the pressing ring 27 is on the same vertical central axis as the tablet pressing cylinder 17 at the corresponding position. A first circular hole is opened on the second mounting platform 19 at the position corresponding to the output rod 26. The output rod 26 is slidably inserted in the first circular hole in a vertical direction. The outer diameter of the pressing ring 27 matches the inner diameter of each set of tablet pressing cylinders 17. When the equipment is started and ready to perform a pressing operation, the controller 4 first issues a command to open the switch valve 5. The powder in the medicine storage cylinder 6 enters the first feeding pipe 24, the connecting pipe 23 and the second feeding pipe 20 from top to bottom through the connecting round pipe. The powder falls from the second feeding pipe 20 into the corresponding loading hole 29 on the second mounting round plate 15. During the feeding and loading process, the servo motor is temporarily held or rotated in a predetermined position to ensure that the loading hole 29 is in the receiving position. As the amount of powder in the loading hole 29 reaches the predetermined amount (according to the timing by the controller 4), the controller 4 commands the switch valve 5 to close to stop the feeding. Then, the controller 4 controls the servo motor to rotate a certain angle, so that the loaded loading hole 29 is rotated to the pressing position, that is, directly below the pressing ring 27. At this time, the pressing cylinder 8 is started, and the output rod 26 drives the pressing ring 27 to move down into the tablet pressing cylinder 17 to press the powder in the cavity. After pressing is completed, the pressing cylinder 8 returns to its original position, the pressing ring 27 rises, and the servo motor continues to drive the second mounting plate 15 and the tablet pressing cylinder 17 to rotate to the next loading position at a predetermined angle. When a certain set of tablet pressing cylinders 17 rotates to align with the position of the dispensing hole 14, the formed tablets fall along the dispensing hole 14 to the dispensing ramp 10 and are guided into the collection device by the splash guard 11. The above process is repeated continuously to achieve a continuous cycle of feeding, positioning, pressing, and tableting, thereby ensuring the timing match between feeding and pressing, avoiding problems such as pressing before the feeding is aligned or premature leakage of powder, and improving the consistency of tablet forming and production stability.

[0022] Furthermore, in this example, such as Figure 2 and Figure 3 As shown, the upper end face of the first mounting circular plate 13 has an annular groove, and the lower end face of the second mounting circular plate 15 has an annular protrusion corresponding to the annular groove. The annular protrusion fits into the annular groove and is slidably connected within the annular groove. The inner wall of the annular groove has a sliding coating. The inner diameter of the dispensing hole 14 is the same as that of each assembly feeding hole 29 and the tablet pressing cylinder 17. The inner diameter of the second feeding pipe 20 is the same as that of the tablet pressing cylinder 17. The middle part of the first mounting circular plate 13 has a section corresponding to the position of the output rotating shaft 28. There is a second circular hole, and a first circular groove is opened at the bottom center of the second mounting circular plate 15 corresponding to the position of the output rotating shaft 28. The output rotating shaft 28 is installed in the second circular hole in a snap-fit ​​rotational manner, and the output rotating shaft 28 is installed in the first circular groove in a fixed manner. One end of the vertical spring 22 is fixedly installed on the bottom outer wall of the first feeding tube 24, and the other end of the vertical spring 22 is fixedly installed on the top outer wall of the second fixing ring 21. The two ends of the connecting tube 23 are respectively slidably inserted into the bottom inner wall of the first feeding tube 24 and the top inner wall of the second feeding tube 20. Under the control of controller 4, the switch valve 5 is first opened, allowing the powder in the medicine storage cylinder 6 to flow through the connecting round pipe into the first feeding pipe 24, connecting pipe 23, and second feeding pipe 20, and then leak from the lower end of the second feeding pipe 20 into the loading hole 29 on the second mounting round plate 15; subsequently, the servo motor drives the output rotating shaft 28 to rotate the second mounting round plate 15 at set intervals, so that each loading hole 29 passes through the feeding position in sequence and is rotated into the working area between the tablet pressing cylinder 17 and the limiting round baffle 16; during the rotation of the second mounting round plate 15, the upper end face of the second feeding pipe 20 and the second mounting round plate 15 are in contact with the second mounting round plate 15. The lower end face of the circular plate 15 slides relative to each other, and when the second feeding pipe 20 slides over the inclined slope 18 provided on both sides of each group of tablet pressing cylinders 17, the second feeding pipe 20 is forced to move upward along the axial direction, thereby compressing the vertical spring 22 sleeved between the first feeding pipe 24, the connecting pipe 23 and the second feeding pipe 20. This elastic buffering action not only avoids the hard collision between the second feeding pipe 20 and the tablet pressing cylinder 17, but also causes the second feeding pipe 20 to fit tightly against the edge of the tablet pressing cylinder 17 after rotation through the spring force, assisting in the alignment correction; at the same time, the first mounting circular plate 13 is provided with an annular groove, and the lower end face of the second mounting circular plate 15 is provided with an annular groove. The end is provided with a matching annular protrusion and the inner wall of the groove is provided with a sliding coating to maintain a good sliding fit and radial positioning between the two circular plates. When the controller 4 detects that the loading hole 29 has been filled with a predetermined amount of powder, the controller 4 controls the switch valve 5 to close and stop feeding. Then, the servo motor drives the output rotating shaft 28 to drive the second mounting circular plate 15 to rotate at a set interval angle, so that the second mounting circular plate 15 rotates to precisely position the loading hole 29, which has been filled with powder, directly below the pressing ring 27. The inner diameters of the discharging circular hole 14, the loading hole 29, the tablet pressing cylinder 17, and the second feeding pipe 20 are the same to ensure guidance and... When the seal is closed, the pressing cylinder 8 is activated, and the output rod 26 drives the pressing ring 27 to move down into the corresponding tablet pressing cylinder 17 to press the powder. After pressing, the pressing cylinder 8 drives the pressing ring 27 to move up and reset, and the servo motor rotates at a predetermined angle to enter the next cycle, thus forming a closed-loop three-step cycle of "opening the valve to quantitatively feed - rotating the turntable and using the inclined plane and spring buffer to achieve automatic alignment - closing the valve to accurately position and start pressing". This achieves high-precision synchronization and reliable cycle of feeding and pressing actions, significantly reduces powder leakage, material shortage and mechanical wear, and ensures the consistency of finished tablets and the stability of equipment operation.
