[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0031] like Figure 1 As shown;

[0032] A double-layer tableting device for producing telmisartan amlodipine tablets includes a base 1 and a lower mold base 11 mounted on the surface of the base 1, and an upper mold base 12 is provided on the surface of the lower mold base 11.

[0033] In this implementation scheme: In the prior art, the tableting process is completed using a base 1. For the specific working principle of the base 1, please refer to the technology disclosed in "CN217319436U discloses a tableting mechanism for a pharmaceutical tableting machine." This technology discloses that "the distance between the cylinder and the lower template is adjusted by fixing the adjusting bolt to the lower or higher first rotating slot, so that the drug powder in the lower template is uniformly pressed. Excessive pressure from the cylinder can be buffered by a spring, facilitating uniform force on the drug powder, thus preventing the tablets from dispersing." However, in this prior art design... Because the production process of telmisartan amlodipine tablets also faces the challenge of higher standards, the existing technology cannot clean up the residual materials. The residual materials will affect the accuracy of subsequent tableting, resulting in large differences in tablet weight, uneven appearance, and even problems such as cracked tablets and sticking tablets. The residual materials may also breed microorganisms, affecting the quality and safety of the drug, leading to an increase in the product non-compliance rate, increasing production costs and the risk of enterprise recall. In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a guiding mechanism 2 and a rotating mechanism 3 are added to this application.

[0034] Furthermore:

[0035] like Figure 1 and Figure 2 As shown:

[0036] Based on the above: a double-layer tableting device for producing telmisartan amlodipine tablets, further comprising a guide mechanism 2 and a rotating mechanism 3 disposed on the surface of the base 1;

[0037] The guiding mechanism 2 includes a frame 21 fixed to the surface of the base 1. A cylinder 22 is mounted on the surface of the frame 21. The push rod at the end of the cylinder 22 is fixedly connected to the upper mold base 12. A rotating mechanism 3 is provided on the surface of the base 1. The rotating mechanism 3 includes a base 31 fixedly connected to the surface of the base 1. A rotating cylinder 32 is rotatably connected to the surface of the base 31. Scrapers 33 are symmetrically fixedly connected to the surface of the rotating cylinder 32.

[0038] In this implementation scheme: the base 1 serves as the main body of the equipment, supporting the lower mold base 11 and the upper mold base 12 to form the tableting mold base. The base 31 of the rotating mechanism 3 is fixed on the base 1. The rotating drum 32 can rotate. The scraper 33 rotates with the rotating drum 32 to clean the surface of the lower mold base 11. It can clean the excess material on the surface of the lower mold base 11 in a timely manner, preventing material residue from affecting the tableting quality and tablet appearance, and improving production efficiency and product qualification rate. In the guiding mechanism 2, the frame 21 is fixed on the base 1. The cylinder 22 push rod is connected to the upper mold base 12. The cylinder 22 extends and retracts to drive the upper mold base 12 to move up and down to complete the tableting action.

[0039] Furthermore:

[0040] like Figure 3 As shown:

[0041] In an optional embodiment, the inside of the rotating drum 32 is provided with a reciprocating groove 34, and a pressing column 35 is slidably connected to the inner surface of the rotating drum 32. A slider 36 is symmetrically fixedly connected to the surface of the pressing column 35, and the slider 36 slides on the surface of the rotating drum 32 through the reciprocating groove 34.

[0042] In this embodiment, the reciprocating groove 34 inside the rotating drum 32 cooperates with the slider 36 on the pressing column 35. When an external force is applied, the pressing column 35 slides up and down inside the rotating drum 32, causing the slider 36 to move along the trajectory of the reciprocating groove 34. Due to the special structural design of the reciprocating groove 34, the sliding of the slider 36 will cause the rotating drum 32 to rotate, thereby driving the scraper 33 to rotate synchronously to complete the cleaning action. By utilizing the cooperation between the reciprocating groove 34 and the slider 36, the linear motion of the pressing column 35 is converted into the rotational motion of the rotating drum 32, realizing the power transmission and motion form conversion, which makes the operation easier.

[0043] Furthermore:

[0044] like Figure 3 As shown:

[0045] In an optional embodiment, a bracket 37 is fixedly connected to the push rod surface at the end of the cylinder 22, and the end of the bracket 37 away from the cylinder 22 is fixedly connected to the pressing post 35.

[0046] In this embodiment: the end rod of the cylinder 22 is fixedly connected to the bracket 37, and the other end of the bracket 37 is connected to the pressing column 35. When the cylinder 22 extends and retracts, it drives the upper mold base 12 to move up and down, and simultaneously drives the pressing column 35 to move up and down through the bracket 37. This makes the movement of the pressing column 35 linked with the pressing action of the upper mold base 12. The up and down sliding of the pressing column 35 drives the rotating drum 32 to rotate, realizing the cleaning operation of the scraper 33. A linkage mechanism between the guide mechanism 2 and the rotating mechanism 3 is established, so that the pressing and cleaning actions are closely combined and coordinated. During each pressing process, the movement of the upper mold base 12 automatically triggers the cleaning action of the scraper 33 without manual intervention or additional control steps, reducing the complexity of equipment operation, ensuring that the surface of the lower mold base 11 can be cleaned in time before each pressing, maintaining the clean state of the mold, and ensuring the stability and continuity of the pressing quality.

[0047] Furthermore:

[0048] like Figure 4 As shown:

[0049] In an optional embodiment, the two sections of the reciprocating chute 34 have different lengths.

[0050] In this embodiment, the asymmetrical design of the reciprocating slide groove 34 causes differences in the distance and speed of the slider 36 on the surface of the pressing column 35 sliding along both sides of the reciprocating slide groove 34 when the pressing column 35 slides up and down inside the rotating cylinder 32. This results in different torques that cause the rotating cylinder 32 to rotate. Furthermore, the specific distance between the lower mold base 11 and the upper mold base 12 means that when the cylinder 22 moves the upper mold base 12 closer to the lower mold base 11, the pressing column 35 moves downwards. Under the action of the reciprocating slide groove 34, the rotation angle, speed, and acceleration of the rotating cylinder 32 exhibit regular changes, achieving rapid, large-angle rotation in the early stages, driving the scraper 3... 3. Rapid rotation ensures that the scraper 33 can promptly disengage from the area between the lower mold base 11 and the upper mold base 12 before the tableting action occurs when the lower mold base 11 and the upper mold base 12 overlap. This avoids interference between the lower mold base 11 and the upper mold base 12. The timely disengagement of the scraper 33 from the tableting area does not affect the normal operation of double-layer tableting, ensuring the continuity and accuracy of the tableting action, improving production efficiency and product quality, reducing downtime and maintenance time and production costs caused by equipment interference, and completing the tablet lifting action on one side. The rotating drum 32 rotates 180 degrees, and the symmetrical design of the scraper 33 ensures continuous cleaning of the surface of the lower mold base 11.

[0051] Furthermore:

[0052] like Figure 3 As shown:

[0053] In an optional embodiment, a rubber strip 38 is fixedly connected to the surface of the scraper 33.

[0054] In this embodiment, the rubber strip 38 fixedly connected to the surface of the scraper 33 plays a role when the scraper 33 rotates with the rotating drum 32 to clean the surface of the lower mold base 11. Since the rubber strip 38 is soft and has a certain elasticity, it can closely fit the surface contour of the lower mold base 11 when it comes into contact with the surface of the lower mold base 11. Even if there are slight unevenness on the surface of the lower mold base 11, the rubber strip 38 can effectively clean the material residue in each corner through its own deformation. At the same time, during the rotation of the rotating drum 32, the elasticity of the rubber strip 38 can buffer the collision force between the scraper 33 and the lower mold base 11, making the cleaning action of the scraper 33 gentler.

[0055] Furthermore:

[0056] like Figure 5 As shown:

[0057] In an optional embodiment, a compression spring A39 is provided inside the pressing post 35.

[0058] In this embodiment: A compression spring A39 is provided inside the pressing column 35. When the pressing column 35 is subjected to external force and moves downward, the compression spring A39 is compressed and stores elastic potential energy. After the pressure is removed, the compression spring A39 releases the elastic potential energy and pushes the pressing column 35 to reset upward. The contact pressure between the pressing column 35 and the reciprocating slide groove 34 slider 36 is adjusted by the elastic force to ensure that the rotating drum 32 rotates smoothly. During the movement of the pressing column 35, it plays the role of buffering external force impact, adjusting the movement force and resetting.

[0059] Furthermore:

[0060] like Figure 5 As shown:

[0061] In an optional embodiment, a rotating plate A310 is rotatably connected to the surface of the base 31, a rotating plate B311 is rotatably connected to the surface of the pressing post 35, and the two ends of the compression spring A39 are fixedly connected to the rotating plate A310 and the rotating plate B311 respectively.

[0062] In this embodiment, the two ends of the compression spring A39 are fixedly connected to the rotating plate A310 and the rotating plate B311 respectively. When the pressing column 35 moves up and down, the rotating plate B311 rotates accordingly and stretches or compresses the compression spring A39. The deformation of the compression spring A39 drives the rotating plate A310 or the rotating plate B311 to rotate, avoiding wear of the base 31 and the surface of the pressing column 35 by the compression spring A39, thereby increasing the service life of the parts.

[0063] Furthermore:

[0064] like Figure 2 As shown:

[0065] In an optional embodiment, three sets of connecting blocks A23 and connecting blocks B25 are fixedly connected to the surfaces of both the lower mold base 11 and the upper mold base 12. A guide post 24 is fixedly connected to the surface of the connecting block A23, and a guide rod 26 is fixedly connected to the surface of the connecting block B25.

[0066] In this embodiment: three sets of connecting blocks A23 and connecting blocks B25 are fixed to the surfaces of the lower mold base 11 and the upper mold base 12, respectively. Connecting block A23 fixes the guide post 24, and connecting block B25 fixes the guide rod 26. When the upper mold base 12 moves up and down under the drive of the cylinder 22, the guide rod 26 cooperates with the guide post 24 to provide multi-directional and multi-point guiding constraints for the movement of the upper mold base 12, ensuring that the upper mold base 12 moves smoothly and accurately in the vertical direction.

[0067] The layout of the three sets of guide pillars 24 and guide rods 26 significantly enhances the stability and guiding accuracy of the upper mold base 12 during movement, disperses the lateral force on the upper mold base 12 during tableting, avoids mold offset and tilting problems caused by uneven force, ensures that the lower mold base 11 and the upper mold base 12 always maintain precise alignment during tableting, makes the pressure evenly distributed on the material, improves the tablet forming quality, reduces the scrap rate caused by mold misalignment, and improves production efficiency and product consistency.

[0068] Furthermore:

[0069] like Figure 6 As shown:

[0070] In an optional embodiment, a sleeve 27 is slidably connected to the surface of the guide rod 26, and a guide groove 28 that mates with the sleeve 27 is opened on the surface of the guide post 24. A compression spring B29 is fixedly connected to the bottom end of the sleeve 27, and the end of the compression spring B29 away from the sleeve 27 is fixedly connected to the connecting block B25.

[0071] In this embodiment: the sleeve 27 is fitted onto the guide rod 26 and can slide along it. At the same time, the sleeve 27 cooperates with the guide groove 28 on the surface of the guide post 24 for guidance. The bottom end of the sleeve 27 is connected to the compression spring B29, and the other end of the compression spring B29 is fixed to the connecting block B25. When the upper mold base 12 moves, it drives the sleeve 27 to slide on the guide rod 26. The compression spring B29 is compressed or extended during the up and down movement of the sleeve 27, which plays a role in buffering, shock absorption and reset, ensuring that the upper mold base 12 moves accurately. The compression spring B29 effectively absorbs the inertial impact force of the upper mold base 12 during start-up, stop and speed change, reduces equipment vibration and noise, reduces mold wear, and extends mold service life. At the same time, the elastic reset function of the compression spring B29 enables the upper mold base 12 to quickly and smoothly reset after completing the tablet pressing action, preparing for the next tablet pressing, improving equipment operating efficiency and tablet pressing quality stability.

[0072] Furthermore:

[0073] like Figure 6 As shown:

[0074] In an optional embodiment, a plurality of balls 210 are rotatably connected to the surface of the sleeve 27.

[0075] In this embodiment, multiple balls 210 are rotatably connected to the surface of the sleeve 27. During the movement of the sleeve 27 and the guide groove 28 on the surface of the guide post 24, the balls 210 roll in contact with the surface of the guide post 24, converting the traditional sliding friction into rolling friction, reducing energy loss, making the upper mold base 12 move more smoothly and quickly, and reducing the energy consumption of the equipment. In addition, the smoother movement process helps to improve the motion accuracy of the upper mold base 12, ensuring the uniformity of the tableting pressure and the quality of tablet forming.

[0076] Working principle: The extension and retraction of cylinder 22 drives the upper mold base 12 to move vertically along guide post 24 and guide rod 26. During this process, three sets of connecting blocks A23 and connecting blocks B25 on the surfaces of the lower mold base 11 and the upper mold base 12 respectively fix the guide post 24 and guide rod 26, providing guidance for the movement of the upper mold base 12. Sleeve 27 is fitted onto guide rod 26 and cooperates with guide groove 28 of guide post 24. Under the action of compression spring B29, the smoothness and accuracy of the movement of upper mold base 12 are further ensured. The ball bearings 210 on the surface of sleeve 27 convert sliding friction into rolling friction, reducing movement resistance. As cylinder 22 drives the upper mold base 12 to move closer to lower mold base 11, it also drives bracket 37 to move downward. During the downward movement of bracket 37, it drives pressing post 35 on the rotating cylinder. The surface of cylinder 32 slides, and the slider 36 on the surface of the pressing column 35 cooperates with the asymmetrical reciprocating groove 34 inside the rotating cylinder 32. The slider 36 slides in the reciprocating groove 34, causing the rotating cylinder 32 to rotate. The asymmetrical design of the reciprocating groove 34 makes the rotation angle, speed and acceleration of the rotating cylinder 32 rotate in a regular manner, driving the scraper 33 to clean the lower mold base 11. The compression spring A39 inside the pressing column 35 is connected to the rotating plate A310 and rotating plate B311, which plays the role of buffering, adjusting contact pressure and assisting in reset, and completing the lifting action of one side of the pressing plate. The rotating cylinder 32 rotates 180 degrees. The symmetrical design of the scraper 33 can achieve continuous cleaning of the surface of the lower mold base 11. After the first layer of pressing plate is completed, the previous step is repeated to press the second layer.

[0077] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
