[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of being able to clean the pressing plate by cooperating with the adjusting threaded rod, the first L-shaped plate, the driving motor, the movable plate, the guide rod, the cleaning brush and the second L-shaped plate. After the tabletting is completed, the upper heating pressing plate and the lower heating pressing plate are moved away from each other, the adjusting threaded rod is driven to rotate by the driving motor, and the movable plate is moved to the front side under the guiding action of the guide rod, so that the cleaning brush is moved to the front side, and then the upper heating pressing plate and the lower heating pressing plate can contact the surface of the cleaning brush, and the adjusting threaded rod is driven by the driving motor to reversely move the movable plate backward, so that the cleaning brush can clean the surface of the upper heating pressing plate and the lower heating pressing plate, and the residual powder on the surface is swept to the right, thereby ensuring the cleanliness of the surface.

[0014] 2. The utility model has the advantage of monitoring the downward pressure by cooperating with the support plate, the first hydraulic cylinder, the pressure sensor, the stabilizer bar and the lower heating platen. When the powder on the surface is tableted, the lower heating platen applies pressure to the pressure sensor, so that the pressure applied by the upper heating platen can be monitored. When the pressure is too high, the first hydraulic cylinder is slightly shortened, driving the support plate to descend, thereby reducing the pressure on the lower heating platen, thereby preventing the pressure from being too high during tableting and affecting the tableting effect.
