Description

Technical Field

[0001] This application relates to the field of pharmaceutical machinery technology, and in particular to a high-speed rotary tablet press for pharmaceutical use. Background Technology

[0002] In the pharmaceutical industry, the pressure regulation accuracy of rotary tablet presses directly affects the stability of tablet quality. Existing rotary tablet presses often use hydraulic cylinders to directly drive the punch, with pressure sensors typically externally mounted or simply installed on top of the punch. This results in issues such as pressure feedback lag, low monitoring accuracy due to direct impact loads acting on the sensor, and a lack of buffering structures. Furthermore, high-speed compression leads to large pressure fluctuations, easily causing uneven tablet thickness, cracking, and other quality defects. Simultaneously, the impact loads exacerbate mold wear, increasing equipment maintenance costs. In addition, the existing pressure regulation component design results in low pressure transmission efficiency, making it difficult to adapt to the dynamic pressure control requirements of high-speed tableting and failing to meet the pharmaceutical industry's production requirements for high-precision and high-stability tablet quality. Therefore, this paper proposes a high-speed rotary tablet press for pharmaceutical applications. Utility Model Content

[0003] The purpose of this application is to provide a high-speed rotary tablet press for pharmaceutical use, which solves the problems of pressure feedback lag, low monitoring accuracy, large pressure fluctuations, and tablet quality defects.

[0004] This application provides a high-speed rotary tablet press for pharmaceutical use, employing the following technical solution: It includes a frame assembly, a turntable assembly, a die assembly, a pressure regulating assembly, and a cooling assembly. The die assembly includes an upper punch, a lower punch, and a middle die. The upper and lower punches are respectively mounted on the upper and lower surfaces of the turntable assembly, and the middle die is fixed in the middle of the turntable assembly. The pressure regulating assembly includes a hydraulic cylinder mounted on the frame assembly. The upper end of the upper punch has a groove, and a movable block is movably connected to the upper end of the groove. A pressure rod is fixedly connected to the side of the movable block near the groove. A pressure sensor corresponding to the pressure rod is provided inside the groove on the side away from the movable block. A spring is sleeved on the surface of the pressure rod and the pressure sensor. One end of the spring is fixedly connected to the side of the movable block near the groove, and the other end is fixedly connected to the side of the groove away from the movable block. The side of the movable block outside the groove corresponds to the output end of the hydraulic cylinder. A downwardly protruding protrusion is provided at the middle of the end of the movable block inside the groove. The height of the protrusion is less than the initial extension length of the pressure rod, and the protrusion corresponds to the bottom of the groove. By adopting the above technical solution and setting the installation layout of the upper punch, lower punch, and middle die of the punch assembly, it is ensured that the force is balanced from top to bottom during the compression of the powder, providing a stable structural foundation for tablet forming. The hydraulic cylinder of the pressure regulating component cooperates with the movable block, combined with the pressure rod, pressure sensor, spring, and protrusion in the upper punch groove. When the movable block moves down, the pressure rod first contacts the pressure sensor to realize real-time pressure detection, the spring buffers the impact load, and the subsequent protrusion transmits the tableting force. This not only ensures the accuracy and continuity of pressure detection and reduces pressure fluctuations, avoiding tablet cracking and uneven thickness, but also solves the existing problem of pressure feedback lag and improves the stability of tablet quality.

[0005] Preferably, the frame assembly includes a base and a column, the base is fixed to the ground by bolts, the column is vertically fixed to the base, and a hydraulic cylinder is installed on the top of the column.

[0006] By adopting the above technical solution, the base of the frame assembly is fixed to the ground with bolts, which enhances the overall stability of the equipment and avoids the equipment shaking during high-speed tablet pressing, thus preventing it from affecting the tablet pressing accuracy. The column is vertically fixed to the base and a hydraulic cylinder is installed on the top, which provides stable installation support for the hydraulic cylinder, ensuring that the output force of the hydraulic cylinder can act vertically on the moving block, ensuring accurate pressure transmission direction, and further improving the reliability of pressure regulation.

[0007] Preferably, the turntable assembly includes a turntable and a drive mechanism. The turntable is connected to the drive mechanism via a main shaft, and the upper punch, lower punch, and middle die are all mounted on the turntable.

[0008] By adopting the above technical solution, the turntable assembly's turntable is connected to the drive mechanism via the main shaft, driving the upper punch, lower punch, and middle die to rotate synchronously, realizing continuous tablet pressing operations and improving production efficiency; at the same time, the unified mounting carrier makes the movement coordination of the three parts stronger, avoiding tablet pressing failures caused by component misalignment and ensuring stable equipment operation.

[0009] Preferably, the cooling assembly includes a cooling coil and a fan, with the cooling coil arranged around the turntable assembly and the fan mounted on the side of the frame assembly.

[0010] By adopting the above technical solution, the cooling coil of the cooling component surrounds the turntable assembly, which can comprehensively cool the turntable and the die assembly, preventing heat accumulation during tableting; the fan is installed on the side of the frame assembly to assist in heat dissipation, accelerate heat dissipation, prevent materials from sticking to the mold due to high temperature, ensure tablet forming quality, and extend the service life of the die assembly.

[0011] Preferably, the hydraulic cylinder of the pressure regulating component can be replaced by a pneumatic cylinder, which is mounted on the frame assembly and corresponds to the movable block.

[0012] By adopting the above technical solutions, the hydraulic cylinder of the pressure regulating component can be replaced with a pneumatic cylinder, providing a variety of options for the pressure driving method of the equipment, which can be flexibly adapted to different production scenarios, thereby improving the applicability and flexibility of the equipment.

[0013] Preferably, the pressure sensor is used to detect the pressure value transmitted to the pressure rod for upward thrust, and a controller is provided on the front side of the base of the frame assembly. The controller is electrically connected to the hydraulic cylinder and the pressure sensor respectively.

[0014] By adopting the above technical solution, the pressure sensor detects the pressure value transmitted by the pressure rod. The controller on the front side of the base is electrically connected to the hydraulic cylinder and the pressure sensor. It can receive pressure signals in real time and adjust the output force of the hydraulic cylinder to form a closed-loop pressure control, avoiding the lag and error of manual adjustment, ensuring that the tableting pressure is always stable within the set range, and further improving the consistency of tablet quality.

[0015] Preferably, the drive mechanism of the turntable assembly includes a servo motor and a reducer, with the servo motor connected to the main shaft of the turntable via the reducer.

[0016] By adopting the above technical solution, the servo motor of the turntable component drive mechanism, in conjunction with the reducer, drives the turntable, which can precisely control the turntable speed. This makes the upper punch, lower punch, and middle die more precisely coordinated at the tableting station, adapting to the requirements of high-speed tableting for the synchronization of speed and pressure, reducing tableting defects caused by speed fluctuations, and improving the stability of the equipment during high-speed operation.

[0017] Preferably, the movable block is fixedly connected to sliders on both the left and right sides of one end inside the groove, and a groove adapted to the slider is opened inside the groove. The slider is movably connected in the groove, and the upper punch and lower punch are made of hard alloy material.

[0018] By adopting the above technical solution, the slider of the movable block cooperates with the groove of the groove to ensure the vertical movement of the movable block, avoid pressure transmission deviation, and ensure pressure adjustment accuracy; the upper and lower punches are made of hard alloy material to enhance their wear resistance and hardness, resist friction and impact during high-speed tableting, reduce mold wear, reduce equipment maintenance costs, extend mold service life, and adapt to the long-term high-speed operation requirements of the equipment.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This high-speed rotary tablet press for pharmaceuticals utilizes a combination structure of a movable block, a pressure rod, a spring, and a pressure sensor. During operation, a hydraulic cylinder pushes the movable block downwards. The pressure rod first contacts the pressure sensor for real-time pressure detection. The spring provides buffering during the pressure rod's compression process, preventing impact loads from directly acting on the pressure sensor. Subsequently, the protrusion of the movable block contacts the upper punch to transmit the tableting force. During this process, the pressure sensor's detection value changes synchronously with the force transmitted by the protrusion, ensuring both the continuity and accuracy of pressure detection. The spring buffer also reduces pressure fluctuations, effectively solving the problems of lag in pressure feedback and low monitoring accuracy in existing technologies. This improves tablet quality stability and reduces defects such as tablet breakage and uneven thickness. The sliders on both sides of the movable block cooperate with the grooves in the upper punch's groove, providing stable guidance during the movable block's up-and-down movement. This ensures that the pressure rod always perpendicularly compresses the pressure sensor, and the protrusion perpendicularly transmits force to the upper punch, preventing uneven pressure transmission caused by movable block misalignment. This further improves pressure adjustment accuracy and ensures consistent tablet compression.

[0020] 2. This high-speed rotary tablet press for pharmaceuticals uses hard alloy materials for the upper and lower punches. The high hardness and wear resistance of the upper and lower punches effectively resist the frequent friction and impact during high-speed tableting. Compared to existing molds made of ordinary materials, this significantly reduces the wear rate, lowers equipment maintenance costs, and extends the mold's service life, meeting the long-term stable operation requirements of high-speed rotary tablet presses. The cooling coils of the cooling system surround the turntable assembly, with a fan assisting in heat dissipation, continuously cooling the turntable and punch assembly. This prevents heat accumulation during tableting, which can lead to material sticking to the mold and ensures tablet forming quality. The stable temperature environment also helps maintain the stability of pressure regulation, indirectly improving tablet compression accuracy. The drive mechanism of the turntable assembly uses a servo motor with a reducer, enabling precise rotational speed control of the turntable. This allows for more precise coordination between the upper and lower punches and the middle mold. Combined with the high-precision pressure control of the pressure regulation component, this meets the requirements of high-speed rotary tableting for dynamic pressure and speed synchronization control, improving overall production efficiency and tablet quality stability.

Figure 1 , Figure 2 and Figure 3The assembly includes a frame assembly 1, a turntable assembly 2, a die assembly 3, a pressure regulating assembly 4, and a cooling assembly 5. The die assembly 3 includes an upper punch 31, a lower punch 32, and a middle die 33. The upper punch 31 and lower punch 32 are respectively mounted on the upper and lower surfaces of the turntable assembly 2, and the middle die 33 is fixed in the middle of the turntable assembly 2. The pressure regulating assembly 4 includes a hydraulic cylinder 41, which is mounted on the frame assembly 1.

The height of the protrusion 317 is less than the initial extension length of the pressure rod 313, and the protrusion 317 is set corresponding to the bottom of the groove 311. By setting the installation layout of the upper punch 31, lower punch 32 and middle die 33 of the punch assembly 3, the upper and lower forces are balanced during the compression of the powder, providing a stable structural foundation for tablet forming; the hydraulic cylinder 41 of the pressure regulating assembly 4 cooperates with the movable block 312, combined with the pressure rod 313, pressure sensor 42, spring 314 and protrusion 317 in the groove 311 of the upper punch 31. When the movable block 312 moves down, the pressure rod 313 first contacts the pressure sensor 42 to realize real-time pressure detection. The spring 314 buffers the impact load, and then the protrusion 317 transmits the tableting force. This not only ensures the accuracy and continuity of pressure detection, reduces pressure fluctuations, avoids tablet cracking and uneven thickness, but also solves the existing pressure feedback lag problem and improves the stability of tablet quality.

The upper punch 31, lower punch 32, and middle die 33 are all installed on the turntable 21. The base 11 of the frame assembly 1 is fixed to the ground with bolts to enhance the overall stability of the equipment and prevent the equipment from shaking during high-speed tablet pressing, which would affect the tablet pressing accuracy.

The cooling coil 51 is arranged around the turntable assembly 2, and the fan 52 is installed on the side of the frame assembly 1. The hydraulic cylinder 41 of the pressure regulating assembly 4 can be replaced with a pneumatic cylinder. The pneumatic cylinder is installed on the frame assembly 1 and corresponds to the movable block 312. The cooling coil 51 of the cooling assembly 5 surrounds the turntable assembly 2, which can comprehensively cool the turntable 21 and the punch assembly 3 to prevent heat accumulation during tableting. The fan 52 is installed on the side of the frame assembly 1 to assist in heat dissipation, accelerate heat dissipation, prevent materials from sticking to the mold due to high temperature, ensure tablet forming quality, and extend the service life of the punch assembly 3. The hydraulic cylinder 41 of the pressure regulating assembly 4 can be replaced with a pneumatic cylinder, providing diversified options for the pressure drive mode of the equipment. It can be flexibly adapted to different production scenarios, improving the applicability and flexibility of the equipment.

[0027] Reference Figure 1 , Figure 4 and Figure 5The pressure sensor 42 is used to detect the pressure value transmitted from the pressure rod 313 to its upper punch 31. A controller 6 is provided on the front side of the base 11 of the frame assembly 1. The controller 6 is electrically connected to the hydraulic cylinder 41 and the pressure sensor 42 respectively. The drive mechanism 22 of the turntable assembly 2 includes a servo motor 221 and a reducer 222. The servo motor 221 is connected to the main shaft of the turntable 21 through the reducer 222. The movable block 312 is located inside the groove 311, and sliders 315 are fixedly connected to both sides of one end. The groove 311 has a groove 316 adapted to the slider 315. The slider 315 is movably connected in the groove 316. The upper punch 31 and the lower punch 32 are made of hard alloy material. The pressure sensor 42 detects the pressure value transmitted by the pressure rod 313. The controller 6 on the front side of the base 11 is electrically connected to the hydraulic cylinder 41 and the pressure sensor 42. It can receive pressure signals in real time and adjust the output force of the hydraulic cylinder 41 to form a closed-loop pressure. To control and avoid the lag and error of manual adjustment, the tableting pressure is kept stable within the set range, further improving the consistency of tablet quality. The servo motor 221 of the turntable assembly 2 drive mechanism 22, in conjunction with the reducer 222, drives the turntable 21, which can precisely control the rotation speed of the turntable 21. This makes the coordination between the upper punch 31, lower punch 32 and the middle die 33 at the tableting station more precise, adapting to the requirements of high-speed tableting for the synchronization of rotation speed and pressure, reducing tableting defects caused by rotation speed fluctuations, and improving the stability of the equipment during high-speed operation. The slider 315 of the movable block 312 cooperates with the slide groove 316 of the groove 311 to ensure that the movable block 312 moves vertically, avoiding pressure transmission deviation and ensuring pressure adjustment accuracy. The upper punch 31 and lower punch 32 are made of hard alloy material to enhance their wear resistance and hardness, resist the friction and impact during high-speed tableting, reduce die wear, reduce equipment maintenance costs, extend die service life, and adapt to the long-term high-speed operation requirements of the equipment.

[0028] In this embodiment, by setting up a combined structure of movable block 312, pressure rod 313, spring 314, and pressure sensor 42, during operation, hydraulic cylinder 41 pushes movable block 312 downward. Pressure rod 313 first contacts pressure sensor 42 to achieve real-time pressure detection. Spring 314 provides buffering during the pressing process of pressure rod 313, avoiding direct impact load on pressure sensor 42. Subsequently, the protrusion 317 of movable block 312 contacts upper punch 31 to transmit pressing force. During this process, the detection value of pressure sensor 42 changes synchronously with the force transmitted by protrusion 317, ensuring both the continuity and accuracy of pressure detection, and also using the spring... The spring 314 buffer reduces pressure fluctuations, effectively solving the problems of pressure feedback lag and low monitoring accuracy in the prior art, improving tablet quality stability, and reducing defects such as tablet cracking and uneven thickness. The sliders 315 on the left and right sides of the movable block 312 cooperate with the sliding grooves 316 in the grooves 311 of the upper punch 31, playing a stabilizing guiding role when the movable block 312 moves up and down, ensuring that the pressure rod 313 always vertically squeezes the pressure sensor 42 and the protrusion 317 vertically transmits force to the upper punch 31, avoiding uneven pressure transmission caused by the offset of the movable block 312, further improving the pressure adjustment accuracy, and ensuring the consistency of tablet compression.

[0029] The implementation principle of this application embodiment is as follows: After the equipment is started, the servo motor 221 of the drive mechanism 22 in the turntable assembly 2 drives the turntable 21 to rotate around the main shaft through the reducer 222. The upper punch 31, lower punch 32 and middle die 33 installed on the turntable 21 rotate synchronously with the turntable 21 and enter the tableting process. The powder to be pressed is filled into the die hole of the middle die 33 and rotates with the turntable 21 to the tableting station. At this time, the upper punch 31 is located directly above the middle die 33 and the lower punch 32 is located directly below the middle die 33, completing the material positioning before tableting. The hydraulic cylinder 41 of the pressure regulating assembly 4 is started, and its output end applies a downward force to the movable block 312. The movable block 312 moves down in the groove 311, and the sliders 315 on the left and right sides slide along the slide grooves 316 in the groove 311 to ensure that the movable block 312 moves vertically. During the downward movement of the movable block 312, the pressure rod 313 on the side close to the groove 311 first contacts the pressure sensor 42 at the bottom of the groove 311. 2. The pressure value is detected and the signal is transmitted to the controller 6. As the movable block 312 continues to move down, the spring 314 sleeved on the surface of the pressure rod 313 and the pressure sensor 42 is compressed, which plays a buffering role. When the protrusion 317 inside the movable block 312 contacts the bottom of the groove 311, the movable block 312 transmits the force of the hydraulic cylinder 41 to the upper punch 31 through the protrusion 317. The upper punch 31 moves down under the force, and works with the lower punch 32 to squeeze the powder in the die hole of the middle die 33, and compress the powder into tablets. During the compression process, the pressure sensor 42 detects the pressure in real time and feeds it back to the controller 6. The controller 6 adjusts the output force of the hydraulic cylinder 41 according to the detection value to ensure stable tableting pressure. The cooling component 5 works continuously during the tableting process. The cooling coil 51 around the turntable component 2 cools the turntable 21 and the punch die component 3. The fan 52 on the side of the frame component 1 assists in heat dissipation to avoid heat accumulation during the tableting process from affecting the tablet forming quality and equipment stability.
