Description

Technical Field

[0001] This application relates to the field of tablet manufacturing, and in particular to a rotary tablet press for tablet manufacturing. Background Technology

[0002] Tablet production refers to the process of mixing the active pharmaceutical ingredient with excipients and then producing a solid dosage form (tablet) through a series of technological steps. Rotary tablet presses are key equipment in the pharmaceutical industry used to compress granular or powdered materials into tablets of a specified shape and size.

[0003] Existing rotary tablet presses typically use guide blades in the feeding assembly to scrape off the powder from the surface of the forming disc. However, the scraping effect of the blades is limited, and powder easily remains on the surface of the forming disc, making them inconvenient to use. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a rotary tablet press for tablet production.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A rotary tablet press for tablet production includes a base, a turntable assembly rotatably connected to the top center of the base, a feeding assembly on one side of the turntable assembly, a material feeding assembly on the other side of the turntable assembly, a cleaning assembly between the feeding assembly and the material feeding assembly, the turntable assembly including a forming disc with a plurality of forming holes on its surface, a stamping disc at both the top and bottom of the forming disc, and a negative pressure chamber including a suction port at both the top and bottom of one end of the negative pressure chamber, a negative pressure interface fixedly installed at the other end of the negative pressure chamber, the suction port being located between the forming disc and the top stamping disc, and the suction port being in contact with the forming disc and the top stamping disc.

[0007] By adopting the above scheme, the base facilitates the internal fixing of the drive motor and transmission mechanism, enabling the turntable assembly to rotate. The forming hole of the turntable assembly sequentially passes through the feeding assembly, unloading assembly, and cleaning assembly, facilitating the pressing and unloading of the powder. The unloading assembly facilitates the export of the pressed tablets for easy collection. The feeding assembly facilitates the storage of powder and fills the forming hole. The cleaning assembly facilitates cleaning the top of the forming plate and the bottom of the top stamping plate after the unloading assembly has finished unloading. The forming hole provides forming space for pressing the powder. The negative pressure interface facilitates connection to an external negative pressure device, allowing the negative pressure chamber to be drawn to negative pressure, creating suction at the suction port. The suction port, in contact with the forming plate and the top stamping plate, facilitates the removal of residual powder from the top of the forming plate and the bottom of the top stamping plate.

[0008] Furthermore, a mounting base is fixedly installed inside the suction port, and cleaning brushes are fixedly installed on the top and bottom of the mounting base.

[0009] By adopting the above solution and setting the mounting base, it is easy to fix the cleaning brush, which facilitates the cleaning brush to sweep off the residual powder on the top of the forming plate and the bottom surface of the top stamping plate, and makes it easy to remove the powder.

[0010] Furthermore, a first fixing column is fixedly installed at the bottom of the negative pressure chamber, and the bottom of the first fixing column is fixedly connected to the top of the base.

[0012] Furthermore, the stamping plate is fixedly equipped with several telescopic rods, and a stamping head is fixedly installed at the output end of the telescopic rods, with the stamping head facing the forming hole.

[0013] By adopting the above scheme, a punch head is fixedly installed at the output end of the telescopic rod, which facilitates the telescopic rod to drive the punch head to move. During the filling stage, the lower punch head rises to a specific height to receive a certain amount of powder. During the pressing process, the upper punch head moves downward to apply pressure to the powder inside the forming hole. The lower punch head remains stable, supporting the material to receive pressure from the upper punch head. After pressing is completed, the lower punch head lifts upward to help push the formed tablet out of the mold.

[0014] Furthermore, the feeding assembly includes a feeding hopper, and a third fixing column is fixedly installed at the bottom of the feeding hopper, with the bottom of the third fixing column fixedly connected to the base.

[0015] By adopting the above scheme and setting the third fixing column, it is easy to fix the feeding component to the base.

[0016] Furthermore, one end of the bottom of the feeding hopper is connected to a material feeding chamber, which is located between the forming plate and the top stamping plate.

[0017] By adopting the above scheme and setting up the feeding hopper, it is convenient to store the medicine powder and to supply the medicine for tablet forming.

[0018] Furthermore, a fabric hole is provided at the bottom of the fabric cavity, and the bottom of the fabric cavity is in contact with the top of the forming disc.

[0019] By adopting the above solution, the setting of the fabric hole makes it easy to fill the powder into the forming hole, and facilitates the stamping head to stamp the powder into shape.

[0020] Furthermore, the feeding assembly includes a feeding tube, and a second fixing column is fixedly installed at the bottom of the feeding tube, with the bottom of the second fixing column fixedly connected to the base.

[0021] By adopting the above solution and setting the second fixing column, it is easy to fix the feeding component on the top of the base.

[0022] Furthermore, a guide plate is provided at one end of the top of the feeding tube, and the top and bottom of the guide plate are in contact with the forming plate and the top stamping plate.

[0023] By adopting the above scheme and setting the guide plate, it is easy to guide the stamped and ejected tablets into the feed tube, which facilitates the collection of the formed tablets.

[0024] In summary, this application has the following technical effects:

[0025] The base design facilitates the internal mounting of the drive motor and transmission mechanism, enabling the turntable assembly to rotate. The forming hole of the turntable assembly sequentially passes through the feeding assembly, unloading assembly, and cleaning assembly, facilitating the pressing and unloading of the powder. The unloading assembly allows for easy export and collection of the pressed tablets. The feeding assembly stores the powder and fills the forming hole. The cleaning assembly cleans the top of the forming plate and the bottom of the top stamping plate after the unloading assembly has finished unloading. The forming hole provides sufficient space for pressing the powder. The negative pressure interface allows for connection to an external negative pressure device, enabling the negative pressure chamber to be drawn into negative pressure, creating suction at the suction port. The suction port, in contact with the forming plate and the top stamping plate, effectively removes residual powder from the top and bottom surfaces of these plates. This invention achieves thorough cleaning of residual powder on the forming plate and has high practical value. Attached Figure Description
