[0026] The utility model is described in detail below with reference to the accompanying drawings: A pharmaceutical tablet press of the utility model comprises a tablet press body 1, a discharging trough 2 is provided on the tablet press body 1, a support frame 3 is provided on the discharging trough 2, a rotating frame 4 is provided on the support frame 3, an iron plate 27 is provided on the support frame 3, and a magnet 29 is installed on the rotating frame 4 through a connecting plate 28; transmission rods 7 are symmetrically provided on the rotating frame 4, and the transmission rods 7 are supported by a second bearing and a second bearing seat 6, and the top of one of the transmission rods 7 is connected to the motor 10; a large gear 8 is provided on one transmission rod 7, and a small gear 9 meshing with the large gear 8 is provided on the other transmission rod 7, so that the two brushes 26 form a speed difference.

[0027] The transmission rod 7 is provided with a sliding block 11, and a retaining ring 12 is provided at the sliding block 11 on the transmission rod 7 for limiting the sliding block 11. A pin 13 is provided in the sliding block 11, and a notch 15 that cooperates with the pin 13 is provided on the transmission rod 7; a push rod 16 is slidably installed at the pin 13 in the transmission rod 7, and a through hole is provided on the side wall of the transmission rod 7 at the push rod 16, and a ball 18 is installed in the through hole. The ball 18 is preferably made of a non-ferromagnetic material, and a first limiting groove 17 that cooperates with the ball 18 is provided on the side wall of the push rod 16, and both sides of the first limiting groove 17 are inclined structures. A sleeve 19 is slidably installed at the bottom end of the transmission rod 7, and a second limiting groove 20 is provided on the inner wall of the sleeve 19 to cooperate with the ball 18. The two sides of the second limiting groove 20 are inclined structures. A square shaft 21 is elastically provided at the bottom of the sleeve 19, and the square shaft 21 extends into the transmission rod 7 and is connected to the push rod 16. The transmission rod 7 can drive the brush 26 to rotate through the square shaft 21; a first spring 24 is provided between the sleeve 19 and the sliding block 11, and the first spring 24 is installed on the sliding block 11; a brush 26 shaft 25 is connected to the sleeve 19, and a brush 26 is installed on the brush 26 shaft 25.

[0028] The brushes 26 on the discharge chute 2 are provided with a plurality of dust suction ports 33, and the dust suction ports 33 of the discharge chute 2 are connected to a dust suction hood 34, which is connected to a dust collector 36 through a pipe 35, and the dust collector 36 is installed on the tablet press body 1 through a mounting bracket; a guide plate 30 is provided on the discharge chute 2 at the brushes 26, for guiding the tablets to between the two brushes 26, and a cover plate 37 is provided on the discharge chute 2 at the guide plate 30 to prevent the tablets from accumulating and overflowing the discharge chute 2.

[0029] Both ends of the rotating frame 4 are rotatably mounted on the support frame 3 via a rotating shaft, and the rotating shaft is supported by a first bearing and a first bearing seat 5 .

[0030] An annular groove is provided on the pin shaft 13 of the sliding block 11 , and a rubber ring 14 is installed in the annular groove to prevent the pin shaft 13 from falling out.

[0031] The bottom of the sleeve 19 is provided with a travel groove 22 , in which a square shaft 21 is slidably mounted, and a second spring 23 is provided between the square shaft 21 and the bottom of the travel groove 22 .

[0032] A gear lever 31 is provided on the side wall of the discharge trough 2 at the brush 26, and a support rod 32 is arranged on the gear lever 31. The gear lever 31 and the support rod 32 can knock the powder on the brush 26 down and then be absorbed by the vacuum cleaner 36, and can also remove the tablets stuck in the brush 26.

[0033] Powder absorption:

[0034] When the tablets fall into the discharge chute 2 and reach the brush 26 through the guide plate 30, the two differentially arranged brushes 26 can push the tablets forward while brushing off the powder on the surface of the tablets. The brushed powder can be sucked in through the dust suction port 33; when the brush 26 rotates, the gear lever 31 can knock off the powder stuck on the brush 26, and then it is absorbed through the dust suction port 33 to keep the brush 26 clean. The support rod 32 on the gear lever 31 can guide the tablets stuck in the brush 26 out.

[0035] Brush disassembly and assembly:

[0036] When the brush 26 needs to be disassembled, the magnet 29 is separated from the iron plate 27 by moving the brush 26 shaft 25, so that the brush 26 is in a naturally drooping state, and then the sliding block 11 is pushed downward. The sliding block 11 drives the pin 13 to move downward, and the pin 13 pushes the push rod 16 to move downward, so that the first limit groove 17 on the push rod 16 reaches the ball 18, and then the inclined surface structure on the second limit groove 20 can push the ball 18 to fall into the first limit groove 17. At this time, the sleeve 19 is ejected under the action of the first spring 24, and the first spring 24 can cover the through hole after being ejected to prevent the ball 18 from falling out.

[0037] When the brush 26 needs to be installed, the sleeve 19 is pushed upward from the bottom end of the transmission rod 7, and the sliding block 11 and the pin 13 can be lifted up by the first spring 24. The elastically arranged square shaft 21 in the sleeve 19 can extend into the transmission rod 7 and lift the push rod 16. As the push rod 16 is lifted up, the ball 18 falls into the second limiting groove 20 in the sleeve 19 under the push of the inclined surface structure on the first limiting groove 17, thereby jamming the sleeve 19. The ball 18 is now located on the outer cylindrical surface of the push rod 16 at the non-first limiting groove 17; after the brush 26 is installed, push the brush 26 to make the magnet 29 adsorbed by the iron plate 27.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
