[0024] Example:
[0025] This embodiment provides a high-speed tablet press, such as Figures 1-3 As shown, it includes an upper pressure roller 1 and a housing 2. The upper pressure roller 1 includes an upper main pressure roller 101 and an upper pre-pressure roller 102. The top of the upper pressure roller 1 is fixedly connected to the top of the inner surface of the housing 2. The housing 2 serves as the main frame of the entire high-speed tablet press, supporting and fixing various components to ensure stable operation of the equipment. The upper track plate 3 is vertically connected to the rotating shaft 4. A first track 5 is recessed on the side wall of the upper track plate 3. The first track 5 on the side wall of the upper track plate 3 is used to guide the movement trajectory of the upper punch 6 so that it can accurately align with the die hole 8 and perform tableting operation. The die hole 8 is used to contain the powder and serves as a mold for tablet forming. The die hole 8 cooperates with the upper punch 6 and the lower punch 9 to complete the tablet pressing.
[0026] The convex groove on the top of the upper punch 6 runs along the first track 5, which is set in a wave shape in the vertical plane, the middle die 7 is connected perpendicularly to the rotating shaft 4, and when the bottom of the upper punch 6 corresponds to the die hole 8 on the middle die 7, the upper punch 6 can be docked with the lower punch 9 and extrude the powder in the die hole 8, the lower punch 9 is placed on the upper surface of the lower track disc 10, the upper surface of the lower track disc 10 is provided with an ejection rail 11, and the geometric center of the lower track disc 10 is connected to the rotating shaft 4, which ensures the synchronous rotation of the upper track disc 3 and the lower track disc 10 and ensures the coordination of the entire tabletting process.
[0027] One side of the lower track disc 10 is provided with a lower pressing wheel 12, which is correspondingly arranged with the upper pressing wheel 1, and the front end of the lower track disc 10 near the lower pressing wheel 12 is provided with a powder box 13, and the inside of the powder box 13 is horizontally provided with stirring paddles 14, which are divided into two groups, each group of stirring paddles 14 contains three to eight paddles, and the paddles are arranged at 60 degrees to the horizontal direction, which makes the stirring of the medicine powder more uniform, the powder box 13 is placed at the front end of the lower track disc 10 near the lower pressing wheel 12, the powder box 13 is used to store medicine powder, and the stirring paddles 14 inside the powder box 13 keep the medicine powder in a uniform and loose state, which facilitates the accurate filling of medicine powder by the upper punch 6 and the lower punch 9 during movement, ensures the consistency of the dose of each tablet, and the design scheme of the stirring paddles 14 can make the medicine powder uniformly dispersed in the powder box, preventing the medicine powder from caking or precipitating.
[0028] The distance between the upper pressing wheel 1 and the lower pressing wheel 12 is less than the distance between the upper track disc 3 and the lower track disc 10, when the upper punch 6 and the lower punch 9 are located between the upper pressing wheel 1 and the lower pressing wheel 12, at this time, the upper punch 6 and the lower punch 9 are closest to each other, then under the docking and cooperation of the upper punch 6 and the lower punch 9, the medicine powder is extruded into tablets in the die hole 8.
[0029] The top of the powder box 13 is provided with a feeding device 15, which is fixedly arranged on one side in the box 2, and the feeding device 15 can deliver tablet raw materials to the powder box 13; this design realizes the delivery of tablet raw materials to the powder box 13. This design ensures that the medicine powder can be continuously and stably supplied to the powder box 13, avoiding the interruption of production caused by insufficient medicine powder during tabletting, thereby improving the production efficiency and continuity.
[0030] The powder box 13 is arranged on the same plane as the lower track disc 10, which is conducive to the accurate entry of the lower punch 9 into the powder box 13 for powder filling during movement. This layout ensures the docking accuracy between the lower punch 9 and the powder box 13, improves the accuracy and stability of powder filling, and thus ensures the consistency of tablet quality. The powder box 13 is provided with an opening 16 on the side close to the rotating shaft 4, which facilitates the smooth entry of the pharmaceutical raw materials in the powder box 13 into the die hole 8 under the rotation of the stirring paddle 14, while avoiding leakage or scattering of the powder, ensuring the cleanliness of the production environment and the utilization rate of the powder.
[0031] One end of the rotating shaft 4 is connected to the output end of the first motor 17, and the rotating shaft 4 and the output end of the first motor 17 are on the same straight line. This connection ensures efficient power transmission, allowing the rotating shaft 4 to stably receive power output from the first motor 17 and transmit it to other components that require power, such as the upper track disc 3 and the lower track disc 10, ensuring the coordination and stability of the entire high-speed tablet press.
[0032] The geometric center of the stirring paddle 14 is connected to the output shaft of the second motor 18. Specifically, the output end of the second motor 18 is meshingly connected to the output end (geometric center) of the stirring paddle 14. This design ensures the balance and stability of the stirring paddle 14 during rotation, thereby improving the stirring effect and ensuring the uniformity and consistency of the powder, and thus ensuring the stability of tablet quality.
[0033] The lower pressure wheel 12 includes a lower main pressure wheel 121 and a lower pre-pressing wheel 122. The upper main pressure wheel 101 and the lower main pressure wheel 121 are correspondingly arranged, and the upper pre-pressing wheel 102 and the lower pre-pressing wheel 122 are correspondingly arranged. This corresponding arrangement allows the upper and lower pressure wheels to work together to pre-press and main-press the powder, ensuring that the powder is fully compacted into tablets. The upper pre-pressing wheel 102 and the lower pre-pressing wheel 122 first preliminarily compact the powder, and the upper main pressure wheel 101 and the lower main pressure wheel 121 then finally compact the powder. This step-by-step compaction method helps to improve the density and hardness of the tablets, ensuring the quality and forming effect of the tablets.
[0034] If necessary for production, the powder box 13 and the feeding device 15 can be provided with two symmetrical groups to improve production efficiency.
[0035] When the device is viewed from above and in working condition, the rotating shaft 4 rotates clockwise, and since the middle die 7 is connected to the rotating shaft 4, the middle die 7 also rotates clockwise. The powder box 13 has a discharge box 19 on the counterclockwise side. A ejection rail 11 is fixedly arranged on the box 2 below the discharge box 19. The ejection rail 11 has a circular arc cross section, which is designed to adapt to the shape of the middle die 7 and the lower rail disc 10 for cooperation. When the lower rail disc 10 carrying the lower punch 9 operates above the ejection rail 11, the ejection rail 11 contacts the lower punch 9 and makes the lower punch 9 lift in vertical height (at this time, the upper punch 6 is vertically upwardly moved under the drive of the first rail 5). Then the lower punch 9 ejects the tablets in the die hole 8. At the same time, since the tablets continuously move in the die hole 8, the tablets continuously move in the tangential direction of the die hole 8 under the action of inertia after being pressed and then ejected by the lower punch 9. Then the tablets fall into the discharge box 19. Finally, the operator can collect the tablets at the end of the discharge box 19. After the tablets are ejected from the die hole 8, the powder box 13 continues to fill the tablet raw materials (i.e. raw material powder) into the idle die hole 8.
[0036] After the tablet is extruded, the tablet passes through the ejection rail 11, and then the tablet moves along the upper rail disc 3 and the lower rail disc 10. The upper rail disc 3 and the lower rail disc 10 are integrally formed.
[0037] The use process of the high-speed tablet press is as follows:
[0038] (1) Equipment starting and stopping: manual starting of the equipment is required. The first motor 17 and the second motor 18 are turned on, so that the rotating shaft 4 starts to operate, thereby driving the upper rail disc 3 and the lower rail disc 10 to rotate, and starting the whole tabletting process. When the production is completed, the equipment is manually stopped.
[0039] (2) Raw material supply of the feeding device 15: Although the feeding device 15 can automatically deliver tablet raw materials to the powder box 13, manual periodic inspection and replenishment of the raw material powder are required to ensure that the feeding device 15 can continuously and stably supply the raw material powder.
[0040] (3) Maintenance and cleaning of the stirring paddle 14: The stirring paddle 14 may have residual or caked powder during operation, which needs to be manually cleaned and maintained regularly to ensure the stirring effect and normal operation of the equipment.
[0041] (4) Installation and replacement of the die (middle die 7): When producing tablets of different specifications or shapes, the middle die 7 needs to be manually replaced to adapt to different production needs.
[0042] (5) Daily inspection and maintenance of the equipment: including checking whether the connection of each part is firm, whether the rail is smooth, and whether the motor is normally operating, which needs to be manually maintained and maintained regularly.
[0043] (6) Quality monitoring and adjustment: During the tabletting process, random samples of tablets are taken for quality testing, such as hardness, thickness, weight, etc. Based on the test results, equipment parameters such as pressure and speed are adjusted.
[0044] (7) Troubleshooting: If the equipment malfunctions during operation, such as powder blockage, punch jamming, etc., manual intervention is required to identify and resolve the problem in a timely manner.
[0045] (8) Cleaning after production: After production, manual cleaning of the residual powder inside and outside the box 2 is required to ensure the cleanliness of the equipment and prepare for the next production.
[0046] The length and arc of the lines of the upper and lower pressure wheels 1 and 12 and the upper and lower punches 6 and 9 are only for illustration, and those skilled in the art can make adaptive adjustments according to actual use.
