[0051] When people need to mix high-efficiency microcrystalline cellulose with povidone excipients, people can use this high-efficiency microcrystalline cellulose and povidone excipient intelligent mixing and molding equipment. First, people manually press the main power switch to power on the device, and then pour the mixed high-efficiency microcrystalline cellulose and povidone excipient mixture into the material receiving chamber 5. Then people manually press the contact switch 4 to make the control module control the output shaft of the first reduction motor 153 to rotate, and the output shaft of the first reduction motor 153 drives the second rotating shaft 154 to rotate, so that the winding wheel 155 rotates, so that the pull rope 156 pulls the workbench 7 to move upward, so that the first cover plate 145 moves upward, so that the first spring 8 is compressed, and when the first cover plate 145 moves upward and contacts the top rod 1 41, the push rod 141 drives the first cover plate 145 to rotate, thereby causing the first torsion spring 144 to twist and deform, causing the first rotating shaft 143 to rotate. When the distance sensor 151 senses that the distance between the first connecting frame 6 on the same side reaches a preset value, the control module controls the first reduction motor 153 to turn off. At the same time, the control module controls the output shaft of the second reduction motor 161 to rotate forty-five degrees and then turn off. The output shaft of the second reduction motor 161 drives the third rotating shaft 162 to rotate, thereby causing the quantitative frame 163 to rotate, causing the strong magnet 164 to rotate. At this time, the mixture in the material receiving chamber 5 slides from the material guiding chamber 9 to between the workbench 7 and the material stop block 174. When the magnetic intensity sensed by the digital Hall magnetic sensor 165 reaches the preset value five seconds later, the control module The output shaft of the second reduction motor 161 is controlled to rotate in the opposite direction forty-five degrees and then closed. The output shaft of the second reduction motor 161 drives the third rotating shaft 162 to rotate in the opposite direction, thereby causing the quantitative frame 163 to rotate in the opposite direction. When the magnetic intensity sensed by the digital Hall magnetic sensor 165 is less than the preset value, the control module controls the output shaft of the first reduction motor 153 to rotate in the opposite direction. The output shaft of the first reduction motor 153 drives the second rotating shaft 154 to rotate in the opposite direction, thereby causing the winding wheel 155 to rotate in the opposite direction, causing the first spring 8 to reset and drive the workbench 7 to move downward and reset, and then the first cover plate 145 moves downward and away from the top rod 141, causing the first torsion spring 144 to reset and drive the first cover plate 145 to reset. When the distance sensor 151 senses the first connecting frame 6 on the same side, When the distance between the workbench 7 and the blocking block 174 is higher than a preset value, the control module controls the heating module 12 to start, so that the heating module 12 heats the mixture between the workbench 7 and the blocking block 174, so that the mixture is heated into a molten state. When the temperature sensor 179 senses that the temperature of the workbench 7 reaches a preset value, the control module controls the heating module 12 to turn off. As time changes, when the temperature sensor 179 senses that the temperature of the workbench 7 is lower than the preset value, the control module electric push rod 177 telescopic rod extends upward for three seconds and then shortens downward for three seconds and then turns off. The telescopic rod of the electric push rod 177 drives the connecting pipe 178 to move upward. When the connecting pipe 178 moves upward and contacts the wedge plate 175, the connecting pipe 178 drives the wedge plate 175 to move outward.As a result, the blocking block 174 moves outward, the first telescopic rod 172 is compressed, and then the second spring 173 is compressed, so that the mixture in the molten state falls into the collection frame 2, and then the electric push rod 177 telescopic rod drives the connecting pipe 178 to move downward, so that the second spring 173 is reset and drives the blocking block 174 and the wedge plate 175 to reset, so that the first telescopic rod 172 is stretched. At this time, if the photoelectric sensor 10 senses that the light is lower than the preset value, it means that there is still a mixture in the material chamber 5. Then the control module controls the output shaft of the first reduction motor 153 to rotate, and then the next round of mixing is performed as described above. When the photoelectric sensor 10 senses that the light reaches the preset value, it means that the remaining mixture in the material chamber 5 is not enough to complete the next round of mixing. At this time, the first reduction motor 153 will not be started. Then people press the main power switch again to power off the device, and then people manually move the collection frame 2 forward to collect the mixture in the molten state in the collection frame 2. After the collection is completed, people move the collection frame 2 backward. ,

[0052] When the temperature sensor 179 senses that the temperature of the workbench 7 reaches a preset value, the control module controls the fan 183 to start, thereby allowing air to flow. When the temperature sensor 179 senses that the temperature of the workbench 7 is lower than the preset value, the control module controls the fan 183 to turn off.

[0053] When people manually press the contact switch 4, the control module simultaneously controls the output shaft of the third reduction motor 192 to rotate, and the output shaft of the third reduction motor 192 drives the fourth shaft 193 to rotate, thereby rotating the stirring frame 194, so that the mixture in the stirring frame 194 is stirred. When the light sensed by the photoelectric sensor 10 reaches a preset value, the control module controls the third reduction motor 192 to turn off.

[0054] When people need to pour the mixture into the receiving chamber 5, they manually rotate the second cover plate 203, thereby rotating the rotating frame 202, rotating the fifth shaft 201, and then twisting the second torsion spring 204. Then people loosen the second cover plate 203, thereby resetting the second torsion spring 204 and driving the rotating frame 202 to reset, so that the second cover plate 203 is reset.

[0055] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
