[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The utility model discloses a pharmaceutical tablet grinder, comprising a mounting platform 1, a grinding box 2 with an open bottom end is mounted on the top of the mounting platform 1, a grinding chamber 4 is formed inside the grinding box 2, a feed port 3 is provided on the top of the grinding box 2, the inner cavity of the grinding chamber 4 is rotatably connected to a turntable 5, an outer wall of the turntable 5 is fixedly connected to an annular sieve plate 6, sieve holes 7 are evenly opened on the sieve plate 6, the inner cavity of the grinding chamber 4 is rotatably connected to a grinding roller 8 whose bottom end is located above the sieve plate 6, and the grinding box 2 is provided with a feeding port 3. A first motor 9 for driving the grinding roller 8 to rotate is installed on the outer wall. The bottom end of the grinding box 2 passes through the mounting platform 1. A boss 12 is installed on the top of the mounting platform 1, which is located in the grinding chamber 4 and below the turntable 5. A discharge chamber 16 is formed between the boss 12 and the bottom end of the side inner wall of the grinding box 2. When the material is added to the grinding chamber 4 through the feed inlet 3 of this pharmaceutical tablet grinder, the material can fall on the turntable 5 and be thrown toward the sieve plate 6 as the turntable 5 rotates, so as to be crushed and ground by the grinding roller 8. The operation is simple and manual intervention is minimal.

[0019] The inner wall of the feed port 3 is arranged to be inclined.

[0020] Specifically, the top height of the sieve plate 6 is lower than the top height of the turntable 5 , and an annular convex edge 10 is fixedly connected to the top of the sieve plate 6 , and a groove 11 is formed between the convex edge 10 , the sieve plate 6 and the turntable 5 .

[0021] In this embodiment, the grinding roller 8 is set at an angle, and the number of the grinding rollers 8 is at least two, and the bottom ends of the grinding rollers are located in the groove 11. When the material falls on the turntable 5, the turntable 5 rotates, and under the centrifugal force, the material can be thrown to the groove 11, so that the grinding rollers 8 perform a crushing and grinding operation.

[0022] Specifically, the boss 12 is in a frustum shape, and the inner wall of the grinding chamber 4 below the turntable 5 is tilted.

[0023] In this embodiment, the inclined inner wall of the grinding chamber 4 cooperates with the boss 12 to facilitate the discharge of the material after the grinding operation.

[0024] Specifically, the bottom end of the boss 12 passes through the mounting platform 1 , a cavity 13 is formed at the bottom end of the boss 12 , a second motor 14 located in the cavity 13 is installed at the bottom of the mounting platform 1 , and an output shaft of the second motor 14 drives the turntable 5 .

[0025] In this embodiment, the second motor 14 drives the turntable 5 to rotate, so that the material falling on the turntable 5 can be thrown toward the groove 11 under the centrifugal force.

[0026] Specifically, a connecting rod is fixedly connected to the top of the turntable 5, and a chopping knife 15 is fixedly provided on the connecting rod.

[0027] In this embodiment, as the turntable 5 rotates, the material will contact the chopping blade 15 when it falls onto the turntable 5 from the feed inlet 3, so that the chopping blade cuts the material.

[0028] Specifically, a material guide cone 17 is installed at the top center of the turntable 5 .

[0029] In this embodiment, when the material falls from the feed port 3 onto the turntable 5 , it contacts the guide cone 17 and conveniently flows along the inclined inner wall of the guide cone 17 toward the groove 11 .
