Figure 1 As shown, the dust suction device comprises: a dust suction body 100; the dust suction body 100 is provided with two dust suction parts; the dust suction end of one of the dust suction parts is suitable for being arranged between the upper punch die plate 400 and the middle die plate 500 of the tablet press; the dust suction end of the other dust suction part is suitable for being arranged between the middle die plate 500 and the lower punch die plate 600 of the tablet press; the dust suction body 100 is provided with an air suction port; the air suction port is connected with the two dust suction parts; the dust suction body 100 is provided with a partition part 200; the partition part 200 is located on the connecting channel between the dust suction part with the dust suction end arranged between the upper punch die plate 400 and the middle die plate 500 and the air suction port; the partition part 200 and the dust suction body 100 are movably connected.

[0039] Here, it should be noted that the dust suction body 100 is arranged adjacent to the tablet press, and one of the dust suction parts of the dust suction body 100 is suitable for sucking the dust left between the upper punch die plate 400 and the middle die plate 500 of the tablet press; the other dust suction part of the dust suction body 100 is suitable for sucking the dust left between the middle die plate 500 and the lower punch die plate 600 of the tablet press; under the action of the two dust suction parts, the tablet press can be effectively cleaned in all directions. Due to the different materials used in molding, sometimes there is less excess powder between the upper punch die plate 400 and the middle die plate 500, while there is more excess dust between the middle die plate 500 and the lower punch die plate 600; the two dust suction parts of the dust suction body 100 work at the same time, and it is easy to suck away the powder that is about to be pressed into tablets in the plate, resulting in material waste, and the movable partition part 200 on the dust suction body 100 can connect or isolate the suction port with the dust suction part at any time, open the partition part 200 when it is necessary to suck the powder between the upper punch die plate 400 and the middle die plate 500, and close the partition part 200 when it is not needed, so as to realize the two dust suction parts working at different times; at the same time, the suction wind speed of the dust suction part can be adjusted by changing the opening degree of the partition part 200, so as to realize the two dust suction parts working with different effects. The overall structure of the present application is simple, easy to use, and can effectively clean the powder, impurities, and dust on the tablet press to prevent the formed tablets from being contaminated.

[0040] Furthermore, it should be noted that the upper punch die plate, the middle die plate and the lower punch die plate in the structure of the tablet press are all prior art.
