[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a discharging mechanism of a rotary tablet press. Figure 1-3 A discharging mechanism of a rotary tablet press comprises a base 1 and a discharging box 10, the top outer wall of the base 1 is fixedly connected with a shaft seat 2, the inner wall of the shaft seat 2 is rotatably connected with a rotating disk 3, the top outer wall of the rotating disk 3 is fixedly connected with a gear disk 4, the top outer wall of the gear disk 4 is fixedly installed with a pushing box 7, the output end of the pushing box 7 is fixedly connected with a guide plate 8 through a fixed block 18, the inner wall of the discharging box 10 is rotatably connected with a rotating shaft 11, the outer wall of the rotating shaft 11 is fixedly connected with a threaded conveying blade 12, the outer wall of the threaded conveying blade 12 is fitted with the inner wall of the discharging box 10, and a driving motor 13 is fixedly installed at one end of the discharging box 10 away from the opening, and the end of the output shaft of the driving motor 13 passes through the discharging box 10 and is fixedly connected to one end of the rotating shaft 11.

[0022] One end of the discharge box 10 is rotatably connected to the outer surface of one side of the base 1 through a connecting piece 9, so that the angle of the discharge box 10 can be easily adjusted to better collect the tablets.

[0023] A discharge port 14 is provided on the top outer wall of the discharge box 10 close to the driving motor 13 . The discharge port 14 is communicated with the inner cavity of the discharge box 10 , and the discharge port 14 corresponds to the guide plate 8 .

[0024] An angle ruler 15 is arranged on the top outer wall of the base 1 around the shaft seat 2 , and a pointer 16 is arranged on the top outer wall of the gear plate 4 . The pointer 16 points to the angle ruler 15 . By the pointer 16 pointing to the angle ruler 15 , the rotation angle of the push box 7 can be clearly understood.

[0027] The implementation principle of the unloading mechanism of a rotary tablet press in the embodiment of the present application is as follows: when in use, the base 1 can be fixed in a suitable position by using a plurality of fastening bolts through a plurality of fixing holes 17, and the servo motor 5 is started to drive the driving gear 6 to rotate.
