A driving shaft 7 is rotatably arranged at the center of the tablet collecting barrel 1 and the feeding barrel 2. A bearing plate 11 is fixedly connected to the tablet collecting barrel 1 and rotatably arranged at the lower middle of the driving shaft 7. An upper bevel gear one 81 is fixedly arranged on the outer wall of the driving shaft 7 below the feeding barrel 2. A plurality of side bevel gears two 82 are meshingly connected to the outer wall of the upper bevel gear one 81. In the present case, four groups of side bevel gears two 82 are arranged. The end of the side bevel gear two 82 is provided with a conveying shaft. A material conveying cylinder 83 for conveying powder is rotatably arranged on the outer side of the conveying shaft. The output side of the material conveying cylinder 83 is a stepped structure with a gradually decreasing inner wall diameter. The material conveying cylinder 83 is fixedly connected to the feeding barrel 2 through a material conveying pipe 10. A spiral auger 84 is fixedly arranged on the outer wall of the conveying shaft in the material conveying cylinder 83.

A material guide plate 87 fixedly connected to the material conveying cylinder 83 is arranged below the extrusion hole 85. A stamping tool 89 for stamping and forming "granular" powder is arranged on the output side of the material guide plate 87. The stamping tool 89 is a functional device for stamping and forming powder in the prior art, and will not be described in detail here. A discharging plate 88 for guiding and outputting tablet particles is arranged on the output side of the stamping tool 89. In this embodiment: the powder enters the feeding cylinder 83 through the feeding pipe 10, as the driving shaft 7 rotates, the upper bevel gear one 81 rotates, the side bevel gear two 82 rotates, the spiral auger 84 outside the conveying shaft rotates rapidly, and the powder raw material is conveyed. Because the circumferential diameter of the end of the feeding cylinder 83 gradually decreases, the powder raw material is continuously extruded and discharged through the extrusion hole 85; As the cutting knife 86 rotates into particles, the "granular" raw material after cutting is punched into tablets by the guide plate 87, and then discharged to the tablet collecting barrel 1 through the blanking tool 89. By first pressing into particles, the method of punching is used, that is, the preliminary extrusion makes the powder particles form a binding force such as van der Waals force and mechanical occlusion, and the plastic deformation ability is enhanced, so that it is easier to form a dense structure during tabletting, which can effectively reduce the cracking or loose tablets caused by elastic shrinkage of the tablets after punching, and improve the qualified rate of tablet granulation; Embodiment two: please refer to Figures 1-6 As shown, in the process of discharging tablets, the traditional way is to let the tablets fall freely to the collecting device, and the tablets will be subjected to a large impact force. For some tablets with brittle texture, it is easy to break during discharging, which reduces the product qualification rate. The following solutions can be used to solve this problem; The lower bevel gear three 91 is arranged on the outer wall below the bearing plate 11 of the driving shaft 7, a plurality of side bevel gears four 92 are connected in meshing manner on the outer side of the lower bevel gear three 91, the number of the side bevel gears four 92 is consistent with that of the side bevel gears two 82, a connecting shaft 96 is arranged at the center of the side bevel gears four 92, a blowing cylinder 94 is rotatably arranged at the end of the connecting shaft 96, a fan 93 is rotatably arranged on the outer wall of the connecting shaft 96 in the blowing cylinder 94, and an inclined blowing pipe 95 is embedded on the output side of the blowing cylinder 94, and the output end of the inclined blowing pipe 95 is arranged towards the blanking plate 88; The stirring rod 6 is rotatably arranged on the outer wall of the driving shaft 7 in the feeding barrel 2, and is used for stirring the powder in the feeding barrel 2; The feeding barrel 2 is provided with a feeding port at the top, and a pair of differential powder crushing parts are rotatably arranged at the feeding port. The powder crushing parts are composed of two groups of rollers 5, and the center of each roller 5 is provided with a mounting shaft rotatably connected with the feeding port. The end of the mounting shaft is provided with a driving motor two for driving the rotation of the mounting shaft, so as to crush the powder and avoid the phenomenon of caking; The bottom of the tablet collecting barrel 1 is provided with a support seat 3 for supporting the tablet collecting barrel 1; and the bottom wall of the tablet collecting barrel 1 is provided with a driving motor one for driving the rotation of the driving shaft 7; The bottom of the tablet collecting barrel 1 is provided with a discharging pipe 4, and the outer wall of the discharging pipe 4 is provided with a control valve for controlling the opening and closing of the discharging pipe 4. Since it is prior art, it is not shown in the figure; In the embodiment, the process of first compacting into pellets and then stamping makes the powder particles form a binding force, the plastic deformation capacity is enhanced, the tablet is easy to form a dense structure, and the tablet granulation qualified rate is effectively improved. When the driving shaft 7 rotates, the lower bevel gear three 91 drives the side bevel gear four 92 to make the fan 93 rotate at high speed, the tablets are blown out upward by the blowing cylinder 94 and the inclined blowing pipe 95, the impact force of the tablets during discharging is further reduced, and the tablets are prevented from being broken due to collision. The foregoing process cooperates with the previous process to comprehensively ensure the tablet production quality. In summary, the powder tabletting process system is constructed by combining the first embodiment and the second embodiment. In the conveying link, the driving shaft 7 drives the upper and side bevel gears to drive the spiral auger 84 to rotate, so that the powder in the feeding cylinder 83 is conveyed to the end portion through the feeding pipe 10. Because the diameter of the end portion gradually decreases, the powder is extruded and compacted, and then discharged through the extrusion hole 85, and then cut into particles by the cutting knife 86. Then, the particles are guided by the guide plate 87, pressed into tablets by the stamping tool 89, and conveyed to the collecting barrel by the discharging plate 88.

[0025] The process of first compacting into pellets and then stamping can make the powder particles form a binding force, enhance the plastic deformation capacity, facilitate the formation of a dense structure, reduce the problems of broken tablets and loose tablets, and improve the granulation qualified rate.
