Description

Technical Field

[0001] This invention relates to the field of pharmaceutical manufacturing molding technology, specifically a tablet pharmaceutical manufacturing molding apparatus. Background Technology

[0002] As is well known, tablets are one of the most widely used dosage forms in clinical practice. Tablet manufacturing equipment is a device used to assist in the molding of tablets. Its core task is to stably and continuously compress uniformly mixed raw materials into tablets that meet the requirements through mechanical pressure.

[0003] A search revealed Chinese patent application CN201820668538.3, which discloses a tableting device for tablet manufacturing. The device is broadly described as including a base plate with supports welded to both ends of its top. A circular ring is welded to the center of the top of the base plate. A turntable, coaxially arranged, is movably fitted onto the inner ring of the top of the ring. A cylindrical mounting groove is formed at the bottom of the turntable. A circular baffle is slidably fitted onto the inner wall of the mounting groove. Lower forming columns, arranged in an array along the axis of the baffle, are threaded onto the top of the baffle. A guide block is vertically welded to the lower forming column near the axis of the turntable. Chinese patent application CN202320310450.5... The patent discloses a swing-type granulation device for tablet drug production. It is generally described as including a chamber, inside which a granulation mechanism and a swing mechanism are arranged. The swing mechanism is located below the granulation mechanism. The granulation mechanism includes an extrusion section, a power section, and a cutting section. The extrusion section is located above the cutting section, and the power section is located to the left of the cutting section. The extrusion section includes a cylinder, a connecting rod, and a pressure plate. The bottom surface of the cylinder is fixedly connected to the top surface of the chamber. The bottom end of the cylinder output rod extends through the top surface of the chamber into the interior of the chamber. In use, the granulation mechanism automatically granulates the tablet drug, and the swing mechanism collects and screens the granules. The swing plate drives the tablet drug to swing and shake, thereby screening excess residue.

[0004] While both of the aforementioned existing technical solutions can achieve tablet production, the former uses a side-push method to push and unload the tablets. However, in reality, most tablets are flat, resulting in a large contact area between their upper and lower ends and a correspondingly large cross-sectional friction. Using a side-push method inevitably causes varying degrees of indentation on the sides of the tablets. The latter method allows for greater openness in tablet forming, resulting in lower controllability of tablet shape. The screening process can also easily cause tablets to aggregate. Once aggregated tablets stick together, it can easily affect the quality of the tablets, and their functionality and reliability need further improvement. Summary of the Invention

[0005] To address the problems in the prior art, this invention provides a tablet manufacturing and molding apparatus. Based on the ability to continuously extrude tablets, it employs a split-type tableting mold, resulting in a shallower tablet compression depth. Demolding is achieved through end-face pushing, leading to better tablet demolding integrity. Furthermore, screening can be performed continuously in batches, reducing the aggregation and adhesion of large quantities of tablets, thus further improving functionality and reliability.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] Example

[0041] Please see Figures 1-18A tablet manufacturing apparatus includes a frame 1 and a feeding assembly. The feeding assembly includes an inclined feeding tube 2, a large spiral feeding tube 3, and a small spiral feeding tube 4. The inclined feeding tube 2 is fixedly connected inside the frame 1. The large spiral feeding tube 3 and the small spiral feeding tube 4 are connected by a gradient guide tube 5. The large spiral feeding tube 3 has multiple circular material passage holes 6, and the small spiral feeding tube 4 has multiple strip-shaped screening holes 7. The integral structure formed by the large spiral feeding tube 3, the gradient guide tube 5, and the small spiral feeding tube 4 is rotatably mounted inside the frame 1. A third... A servo motor 8 is used for the synchronous rotation drive of the small spiral feed tube 4, the gradient guide tube 5, and the large spiral feed tube 3. A support ring 38 is fixedly connected inside the frame 1. A receiving ring 39 is rotatably connected inside the support ring 38. The receiving ring 39 is provided with a sloped annular surface 49, which has a gradient trend of a smaller inner diameter at the front and a larger inner diameter at the rear. The receiving ring 39 is used to receive tablets removed from the tablet cavity 22 and assist in conveying the received tablets to the large spiral feed tube 3. The receiving ring 39 is fixedly connected to the large spiral feed tube 3. The feed pipe 3 is connected, and a support shaft 40 is fixedly connected inside the large spiral feed pipe 3. The support shaft 40 is fixedly connected to the small spiral feed pipe 4. A suspension frame 41 is fixedly connected to the rear end of the frame 1. The support shaft 40 is rotatably connected to the suspension frame 41. The first servo motor 8 is installed on the rear side of the suspension frame 41, and the output shaft of the first servo motor 8 is drivenly connected to the support shaft 40. The design of the feeding component can be matched with the entire process of tablet and drug forming, forming an auxiliary guiding feeding structure. It achieves good feeding continuity while screening tablets and drugs and residue, ensuring orderly auxiliary feeding during tablet and drug forming. To reduce the adhesion between tablets and ensure better quality stability during batch production, a fragment box 42 and a powder collection box 43 are fixedly connected inside the frame 1. The fragment box 42 and the powder collection box 43 are located directly below the large spiral feed tube 3 and the small spiral feed tube 4, respectively. The powder collection box 43 has a central bulge. The fragment box 42 is fixedly connected to the support ring 38. When the tablets enter the small spiral feed tube 4 through the large spiral feed tube 3, the residual powder on the tablets will fall into the powder collection box 43 under its own gravity, realizing powder recovery and improving the cleaning effect of the tablets.

[0042] It should be further explained that a double-sided conveyor forming assembly is installed inside the frame 1. The double-sided conveyor forming assembly is matched with the inclined feed pipe 2. A receiving guide arc plate 9 is fixedly connected inside the frame 1. The receiving guide arc plate 9 is used for the stepped connection between the inclined feed pipe 2 and the large spiral feed pipe 3. The double-sided conveyor forming assembly includes two conveyor belts 10, both of which are installed inside the frame 1. A first inclined mounting frame 27 and a second inclined mounting frame 28 are fixedly connected inside the frame 1. A first drive wheel 29 and a first driven wheel 30 are rotatably connected to the first inclined mounting frame 27. A second drive wheel 31 and a second driven wheel 32 are rotatably connected to the second inclined mounting frame 28. The two conveyor belts 10 are respectively connected to the first driven wheel 30 and the second driven wheel 32. Driven wheel 32 is connected to the drive wheel, and the two conveyor belts 10 are also connected to the first drive wheel 29 and the second drive wheel 31 respectively. The bottom end of the first inclined frame 27 is equipped with a second servo motor 33, and the output shaft of the second servo motor 33 is connected to the first drive wheel 29. The bottom end of the first inclined frame 27 is rotatably connected with a lower extension shaft 34. Synchronous gears 35 are installed on both the lower extension shaft 34 and the first drive wheel 29. The two synchronous gears 35 are meshed and connected to each other. Synchronous pulleys 36 are installed on both the lower extension shaft 34 and the second drive wheel 31. The two synchronous pulleys 36 are connected to each other through a synchronous soft belt 37. The inclined feed pipe 2 is set between the two conveyor belts 10. The conveyor belt 10 on the right side is located between the two conveyor belts 10. Multiple first positioning frames 11 are installed on the conveyor belt 10 located on the left side, and multiple second positioning frames 12 are installed on the conveyor belt 10 located on the left side. The first positioning frames 11 are equipped with a first pressing frame 13 and a first extrusion frame 14 via a first composite elastic element. The first extrusion frame 14 is fitted within the first pressing frame 13. The second positioning frames 12 are equipped with a second pressing frame 15 and a second extrusion frame 16 via a second composite elastic element. The second extrusion frame 16 is fitted within the second pressing frame 15. Both the first and second composite elastic elements include sliding frames 17. The first positioning frames 11 and the second positioning frames 12 are slidably connected to the two sliding frames 17 respectively. The sliding frames 17 are fixedly connected to a first spring 18, a second spring 19, and a third spring 20. The first positioning frame 11 and the second positioning frame 12 are respectively fixedly connected to two first springs 18. The second spring 19 is fixedly connected to a bridging plate 21. The third spring 20 is fixedly connected to the bridging plate 21. The first extrusion frame 14 and the second extrusion frame 16 are respectively fixedly connected to the two bridging plates 21. Through the design of the double-sided conveying molding assembly, the auxiliary molding operation of pharmaceutical raw materials into tablets can be realized. The split tableting mold allows the tablets to be pressed into the second extrusion frame 16 and the first extrusion frame 14 to a smaller depth. The tablets are demolded by pushing from the end face, resulting in better demolding integrity and less impact on the normal conveying of tablets during the molding process, making it more practical.

[0043] Furthermore, each of the multiple first extrusion frames 14 and multiple second extrusion frames 16 is provided with a sheet-shaped cavity 22. A stepped hole is formed within the sheet-shaped cavity 22, and an embedded post 23 is slidably connected within the stepped hole. A side tension spring 24 is fixedly connected to the embedded post 23 and is fixedly connected to the bridge plate 21. The first extrusion frame 14 has a first movable material passage 25, and the second extrusion frame 16 has a second movable material passage 26. The first movable material passage 25 and the second movable material passage 26 are matched. When the corresponding first extrusion frames 14 and second extrusion frames 16 are in contact with each other, the two opposite sheet-shaped cavities 22 cooperate to form a complete sheet cavity structure. The pharmaceutical raw materials within the tablet cavity structure are compressed into tablet structures. Simultaneously, the reverse pushing force of the tablets causes the insert post 23 to move. During this movement, the insert post 23 overcomes the elastic tension of the side tension spring 24 and retracts into the stepped hole. Accompanying the movement of the conveyor belt 10, when the first extrusion frame 14 and the second extrusion frame 16 separate, the side tension spring 24 pulls the insert post 23 out of the stepped hole, facilitating the auxiliary ejection and feeding of the tablets within the tablet cavity 22, preventing the tablets from sticking inside. The inclined feed pipe 2 is equipped with double-sided openings 45, which match the first extrusion frame 14 and the second extrusion frame 16 to achieve the first extrusion... The auxiliary limiting of the tablet holder 14 and the second extrusion holder 16 ensures the phased approach of the first extrusion holder 14 and the second extrusion holder 16 towards the drug raw material, avoiding excessive single extrusion amplitude that could cause tablet defects. The top of the inclined feed tube 2 is connected to a feeding box 46, on which a suspension shell 47 is installed. An electric screw conveyor 48 is installed on the suspension shell 47. The electric screw conveyor 48 is a combination structure of a servo motor and a screw conveyor shaft. When the servo motor is powered on, it can drive the rotation of the screw conveyor shaft. The rotating screw conveyor shaft can form auxiliary extrusion on the material in the feeding box 46 to ensure that the drug raw material enters relative to the inclined feed tube 2. To ensure continuity and saturation, a receiving box 51 is provided at the bottom of the receiving guide arc plate 9 to assist in receiving accidentally dropped tablets. A receiving box 52 is provided below the rear outlet of the small spiral feed tube 4 to receive the prepared tablets. Two unloading plates 44 are installed inside the frame 1, and a diagonal hanging rod 50 is fixedly connected inside the frame 1. Both unloading plates 44 are fixedly connected to the diagonal hanging rod 50. The two unloading plates correspond to the outer sides of the two conveyor belts and correspond to the movement trajectories of the first extrusion frame and the second extrusion frame, respectively. When tablets adhere to the embedded column 23, the tablets can be pushed out a second time to improve the reliability of the unloading operation.

[0044] In this embodiment, the first servo motor 8, the second servo motor 33, and the electric screw conveyor 48 are all commercially available conventional devices known to those skilled in the art. In this invention, we simply use them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0045] In summary, the working principle of this tablet manufacturing and molding device is as follows: Before use, the first servo motor 8, the second servo motor 33, and the electric screw conveyor 48 are electrically connected. The connection status of each transmission component is checked. After starting the equipment and waiting for the overall equipment to run smoothly, the pharmaceutical raw material is added into the feeding box 46. The servo motor in the electric screw conveyor 48 is powered on and runs, driving the screw conveyor shaft to rotate, forming a continuous auxiliary extrusion on the pharmaceutical raw material in the feeding box 46, so that the pharmaceutical raw material is stably conveyed along the inclined feed pipe 2. At the same time, the tablet is formed by double-sided conveying. The second servo motor 33 in the assembly drives the first drive wheel 29 to rotate, which in turn drives the lower extension shaft 34 to rotate synchronously via two meshing synchronous gears 35. The synchronous pulley 36 on the lower extension shaft 34 drives the second drive wheel 31 to rotate via the synchronous soft belt 37, thereby enabling the two conveyor belts 10 to rotate synchronously in opposite directions between the first drive wheel 29 and the first driven wheel 30, and between the second drive wheel 31 and the second driven wheel 32, respectively. The conveyor belts 10 drive multiple first positioning frames 11 and multiple second positioning frames 12 on them to move synchronously. As the two conveyor belts 10 move in the same direction, the first drive wheel 29 rotates in opposite directions. As the first and second pressure tube frames 13 and 15 move closer together, they first make relative contact with the inclined feed tube 2. Then, when the first and second pressure tube frames 13 and 15 are fully fitted together, they can wrap around and enclose the inclined feed tube 2. During this process, the two corresponding first springs 18 are first compressed and then extended to accommodate the movement of the first and second pressure tube frames 13 and 15 around the inclined feed tube 2. At the same time, the first extrusion frame 14 and the second extrusion frame 16 on the left and right sides gradually approach each other. After the first pressure frame 13 and the second pressure frame 15 come into contact with the inclined feed pipe 2, the first extrusion frame 14 and the second extrusion frame 16 will be pushed into the corresponding first pressure frame 13 and the second pressure frame 15 by the auxiliary pushing action of the inclined feed pipe 2. During this stage, the corresponding second spring 19 and the third spring 20 will be elastically compressed, and the first extrusion frame 14 and the second extrusion frame 16 on the left and right sides will gradually move away from each other.

[0046] Furthermore, as the conveyor belt 10 moves, the first pressing frame 13 and the second pressing frame 15, which are in contact with each other on the left and right, will move synchronously with the two conveyor belts 10. During this movement, the first pressing frame 13 and the second pressing frame 15 fall synchronously along the inclined feed pipe 2. When the first pressing frame 13 and the second pressing frame 15 move to the area of ​​the two double-sided openings 45, the first extrusion frame 14 in the first pressing frame 13 and the second extrusion frame 16 in the second pressing frame 15 will approach each other under the elastic reset action of the corresponding second spring 19 and third spring 20, until the first extrusion frame 14 and the second extrusion frame 16 approach each other and the double-sided openings 45. The long, flat surfaces of the conveyor belt 10 make contact, thus creating a certain amount of compression on the raw pharmaceutical material inside the inclined feed tube 2. As the conveyor belt 10 moves further, after the first extrusion frame 14 and the second extrusion frame 16, which were in contact with the inclined feed tube 2, are completely removed from the inclined feed tube 2, they will also come into contact with each other. This contact will cause the corresponding two tablet cavities 22 to combine, compressing the raw pharmaceutical material between the first extrusion frame 14 and the second extrusion frame 16 into tablets. Since the space between the two combined tablet cavities 22 is smaller than the space of the corresponding section within the inclined feed tube 2, therefore... During this process, the pharmaceutical raw material is further compressed. Due to the reverse pushing effect of the pharmaceutical raw material on the embedded post 23, the side tension spring 24 will elastically elongate, thereby causing the corresponding embedded post 23 to retract into the stepped hole, ensuring the full shape of the tablet. Furthermore, since the rear ends of the first extrusion frame 14 and the second extrusion frame 16 are closed, while the front ends of the first live material channel 25 and the second live material channel 26 have channels communicating with the inclined feed pipe 2, after the pharmaceutical raw material has filled the two interlocking tablet cavities 22, excess pharmaceutical raw material can also flow back relative to the inclined feed pipe 2 through the extrusion force. When the first extrusion frame 14 and the second extrusion frame 16 are positioned to the left and right, the excess pharmaceutical raw material can flow back relative to the inclined feed pipe 2. After the tablet holders 16 come into contact with each other, the communication channel between the first extrusion holder 14 and the second extrusion holder 16 that came into contact with each other in the previous step and the inclined feed pipe 2 will be closed, that is, the first live material channel 25 and the second live material channel 26 will be blocked and sealed, so as to achieve complete separation of the formed tablet medicine from the medicine raw material in the inclined feed pipe 2. As the conveyor belt 10 moves further, when the first extrusion holder 14 and the second extrusion holder 16 move and separate from each other, the tablet medicine between them will fall off. During the separation process, the side tension spring 24 will cause the embedded post 23 to extend out of the stepped hole to assist in pushing the tablet medicine relative to the tablet cavity 22 to fall off, preventing the tablet medicine from sticking together in the tablet cavity 22.

[0047] Furthermore, the tablets fall onto the receiving guide plate 9 and descend along it into the receiving ring 39. Guided and rotated by the sloping annular surface 49 of the receiving ring 39 (smaller at the front and larger at the back), the tablets smoothly enter the large spiral feed tube 3, which is fixedly connected to it. As the first servo motor 8 drives the support shaft 40 to rotate via its output shaft, the support shaft 40 drives the large spiral feed tube 3, the gradient guide tube 5, and the small spiral feed tube 4 to rotate synchronously. Under the spiral guidance of the large spiral feed tube 3, the tablets move slowly. Due to the spiral structure of the large spiral feed tube 3... The mechanism drives the tablets to slide and flip, ensuring continuous contact between the tablets and the adjacent circular feed hole 6. This allows for the screening out of fragments within the tablets. The fragment box 42 then collects these fragments. To prevent intact tablets from passing through the circular feed hole 6, the diameter of the hole should be smaller than the tablet diameter. Furthermore, to enhance the contact between the tablets and the circular feed hole 6, a stepped slope structure can be incorporated into the large spiral feed tube 3 to strengthen the contact and compression effect between the tablets and the circular feed hole 6. A detailed schematic diagram is attached. Figure 17 As shown, the tablets are conveyed through the large spiral feed tube 3 and then through the gradient guide tube 5 into the small spiral feed tube 4. During the continued conveying process in the small spiral feed tube 4, the residual powder on its surface falls into the powder collection box 43 below under the action of gravity through the strip sieve holes 7. The raised structure in the middle of the powder collection box 43 guides the powder to collect on both sides for easy subsequent recycling and removal. The processed finished tablets are discharged from the rear outlet of the small spiral feed tube 4 and fall into the tablet collection box 52 below, completing the entire tablet forming, sieving, and collection process. Due to the conveying channel formed by the large spiral feed tube 3, the small spiral feed tube 4, and the gradient guide tube 5, good differentiation of tablets can be achieved, perfectly avoiding the adhesion of tablets during the preparation process, as shown in the attached figure. Figure 18 The diagram shows the working principle of the unloading plate 44. The straight arrows indicate the direction of the unloading plate 44 pushing the tablets attached to the embedded column 23. The curved arrows indicate the movement of the tablets attached to the embedded column 23. The overlapping parts of the components indicate the trajectory of the movement, not the spatial interference between the components.
