The pushing mechanism 7 also includes a motor 79 installed on the right side surface of the tablet press body 5 and used to rotate the two driven gears 78. By arranging a slidable discharge pipe 6, a gasket 9, a spring 10, a connecting block 11 and a pushing mechanism 7, the discharge pipe 6 can be reciprocated up and down during discharge, thereby preventing the tablets from being blocked during discharge, and there is no need to manually clear the discharge pipe 6, thereby making the production efficiency of the tablets higher.

[0031] In this embodiment, the driving mechanism 7 also includes a rotating shaft 710 coaxially connected to the output shaft of the motor 79. A driving gear 711 meshing with the two driven gears 78 is coaxially fixed on the outer wall of the rotating shaft 710, which can smoothly drive the two driven gears 78 to rotate.

[0032] In addition, two guide grooves are provided on the right side surface of the tablet press body 5, and a guide block 73 is fixed on the left side surface of the guide rod 72, which is slidably connected to the guide groove on the same side of the right side surface of the tablet press body 5, and can guide the movement of the two guide rods 72.

[0033] Furthermore, the right side surface of the tablet press body 5 is provided with two I-shaped slide grooves in a transverse cross-section, and the left side surface of the discharge pipe 6 is fixed with two slide bars 12 that are slidably connected to the slide grooves on the same side of the right side surface of the tablet press body 5, which can guide the movement of the discharge pipe 6 and prevent the discharge pipe 6 from separating from the tablet press body 5.

[0034] Furthermore, the pushing mechanism 7 also includes a protective pad 77 fixed to the bottom end of the pushing block 76, and the shape of the bottom surface of the protective pad 77 is adapted to the shape of the top surface of the discharge pipe 6, which can protect the discharge pipe 6.

[0035] Specifically, the transverse cross-sectional shape of the guide groove on the right side surface of the tablet press body 5 is convex, and the shape of the guide block 73 is I-shaped which is compatible with the shape of the guide groove on the right side surface of the tablet press body 5. This can make the connection between the guide block 73 and the guide groove on the surface of the tablet press body 5 tighter, prevent the guide block 73 from being separated from the guide groove on the surface of the tablet press body 5, and make the double-sided rack 71 more stable.

In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0040] In the specific use process of this embodiment, when the tablet press body 5 is working, the motor 79 is started by the external PLC, and the output shaft of the motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate, and the rotating shaft 710 rotates to drive the driving gear 711 meshing therewith to rotate, and the driving gear 711 rotates to drive the two driven gears 78 meshing therewith to rotate, and the driven gear 78 rotates to drive the rotating rod 75 coaxially fixed thereto to rotate, and the rotating rod 75 rotates to drive the half gear 74 coaxially fixed thereto to rotate, and the half gear 74 rotates to drive the double-sided rack 71 meshing therewith to move, and the two half gears 74 are staggeredly meshed with the double-sided rack 71, so that the double-sided rack 71 reciprocates up and down, and the double-sided rack 71 moves under the guidance of the two guide blocks 73, the two guide rods 72 and the two guide grooves on the right side surface of the tablet press body 5;

[0041] When the double-sided rack 71 moves downward, the double-sided rack 71 drives the push block 76 and the protective pad 77 to move downward. After the protective pad 77 contacts the discharge pipe 6, the discharge pipe 6 moves downward. The discharge pipe 6 moves under the guidance of the two slide bars 12 and the two slide grooves on the right side surface of the tablet press body 5. The movement of the discharge pipe 6 drives the spring 10 to be compressed. When the double-sided rack 71 moves upward, the discharge pipe 6 can be returned to the initial position. The double-sided rack 71 reciprocates up and down, which can make the discharge pipe 6 reciprocate up and down to prevent the tablets from being blocked when being discharged. When the tablet press body 5 finishes working, the motor 79 is turned off by the external PLC.
