[0029] 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 protection scope of the present utility model.

[0030] Reference Figures 1-2 This utility model provides an embodiment of a tablet press for tablet production, including a worktable 1. A support 2 is fixedly connected to the top of the worktable 1, which provides support. An electric telescopic rod 5 is fixedly connected to the inner side of the top of the support 2. A hydraulic rod 6 is fixedly connected to the inner wall of the top of the worktable 1. An electric push rod is provided on the top of the worktable 1, which can drive the horizontal plate to move, thereby discharging the pressed tablets. An adjustment mechanism 3 is provided at the bottom of the electric telescopic rod 5. The electric telescopic rod 5 drives the adjustment mechanism 3 to move, and the adjustment mechanism 3 is provided in two sets.

[0031] Reference Figures 2-4The adjusting mechanism 3 includes a fixed frame 301 fixedly connected to the bottom of the electric telescopic rod 5. The fixed frame 301 is driven to move synchronously through the movable end of the bottom of the electric telescopic rod 5. A fixed plate 302 is fixedly connected to the bottom outer wall of the fixed frame 301. One set of fixed frames 301 corresponds to two sets of fixed plates 302. A rotating column 304 is rotatably connected to the inner wall of the fixed plate 302. The rotating column 304 passes through the fixed plate 302. A stamping box 303 is fixedly connected to the center of the rotating column 304. A positioning plate 307 is fixedly connected to the right side of the fixed plate 302. One set of fixed plates 302 corresponds to two sets of positioning plates 307. The positioning plate 307 is designed with... The rotating column 304 is L-shaped, and a square plate 309 is fixedly connected to the right side of the rotating column 304. The square plate 309 can be better connected and fixed than the rotating column 304. There are two sets of rotating columns 304. The outer arc surface of the other set of rotating columns 304 is fixedly connected to a connecting plate 305. There are two sets of connecting plates 305. The outer wall of the connecting plate 305 is fixedly connected to a stamping die 306. The setting of the stamping box 303 and the stamping die 306 can then perform tableting operation. An indicator 4 is set on the right side of the fixed plate 302. The setting of the indicator 4 makes it easy to know that the rotation range of the stamping box 303 and the stamping die 306 is the same.

[0032] Reference Figures 2-4 The fixing frame 301 is concave, which facilitates the connection of the fixing plate 302. The positioning plate 307 is fixedly connected to the inner wall of the square plate 309 by bolts 308, which enables quick fixing. The fixing plate 302 has a square groove on the side away from the fixing frame 301. The width of the inner surface of the square groove is the same as the thickness of the side wall of the bracket 2. The square groove can guide the fixing plate 302. The outer wall of the stamping die 306 has multiple sets of through holes. The outside of the stamping box 303 has multiple sets of stamping heads. The front through holes correspond to the front stamping heads. The front and rear holes correspond to each other. This arrangement facilitates the molding of tablets of different specifications.

[0033] Reference Figure 5 The indicator 4 includes a rotating shaft 401 fixedly connected to the right end of the square plate 309. There are two sets of rotating shafts 401, and the two sets of rotating shafts 401 face the same direction. The consistent orientation makes it easy for the staff to judge whether the rotation angle of the stamping box 303 and its stamping die 306 is consistent. The rotating shaft 401 is Z-shaped, which makes it easy for the staff to manually rotate the rotating column 304.

[0034] Working principle: When tablets need to be compressed, the electric telescopic rod 5 is activated and the hydraulic rod 6 pushes the material upward to the pressing position. The pressing head of the pressing box 303 cooperates with the through hole of the pressing die 306 to complete the tableting.

[0035] If it is necessary to change the tablet size, loosen the bolts 308 connecting the positioning plate 307 and the square plate 309, and rotate the rotating column 304 through the Z-shaped rotating shaft 401 to drive the stamping box 303 and the stamping die 306 to rotate, so that the stamping head of the corresponding size is aligned with the through hole of the material (such as rotating the front stamping head to the working position). Since the two sets of rotating columns 304 are linked through the connecting plate 305 and the rotating shaft 401 faces the same direction, the operator can judge whether the rotation angle is consistent by observing whether the rotating shaft 401 is aligned, ensuring that the stamping head and the through hole are accurately aligned. After adjustment, tighten the bolts 308 to fix it. The square groove of the fixing plate 302 cooperates with the side wall of the bracket 2 to provide guidance for the pressing process and ensure stamping accuracy. The design of the concave fixing frame 301 and the L-shaped positioning plate 307 not only ensures the structural strength, but also facilitates quick disassembly and replacement of the die, realizing the efficient production of tablets of different sizes.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
