[0029] Please refer to the attached drawings in the manual Figure 1 and Figure 2One embodiment of the present application provides a wet mixing granulator, comprising a frame 18, on which are mounted two motors 36. The output ends of the two motors 36 are detachably mounted with a single cylinder 1. The cylinder 1 has a feed port 11, which is used to accommodate drug powder and adhesive. A discharge port 12 is provided on the side wall of the cylinder 1, near its bottom. A stopper 7 is hingedly mounted on the cylinder 1, capable of blocking the discharge port 12. The stopper 7 can be fixed to the cylinder 1 via screws to close the discharge port 12. A stirring paddle 2 is rotatably and sealably mounted at the bottom of the cylinder 1. The stirring paddle 2 is driven to rotate by a motor 3, with its axis of rotation perpendicular to the ground. The stirring paddle 2 is used to stir the drug powder and adhesive to ensure a uniform mixture. A cutting tool 4 is installed in a rotary seal on the side wall of the material cylinder 1. The cutting tool 4 is driven to rotate by a motor 2 5. The cutting tool 4 includes a rotating shaft and several tools installed on the shaft. The motor 2 5 is used to drive the rotating shaft to rotate. The rotating axis of the cutting tool 4 is parallel to the ground, thereby cutting the mixed material into particles. The cut particles can be discharged through the discharge port 12.

[0030] Please refer to the attached drawings in the manual Figure 3 The motor 3 6 is a forward and reverse motor. The motor 3 6 can use a limit motor. The motor 3 6 can drive the material cylinder 1 to rotate clockwise by a certain angle to tilt the bottom surface of the material cylinder 1, thereby making the discharge port 12 close to the ground, and the rotation axis of the material cylinder 1 is parallel to the ground. This design can make the particles more fully pass through the discharge port 12 to discharge. Two electric push rods 9 are installed on the frame 18. The two electric push rods 9 are used to drive the same support block 8 to rise or fall vertically. The upper surface of the support block 8 is used to contact the lower surface of the material cylinder 1 in a horizontal state, thereby supporting the material cylinder 1. When the material cylinder 1 needs to be disassembled, the motor 3 is removed first, and the electric push rod 9 is turned on to make the upper surface of the support block 8 contact the bottom surface of the material cylinder 1 in a horizontal state. At this time, the support block 8 can support the material cylinder 1, and the material cylinder 1 can be removed from the output end of the motor 3 6. Compared with not using the support block 8, there is no need to manually hold the material cylinder 1 to disassemble the motor 3 6, which is more convenient.

[0031] Please refer to the attached drawings in the manual Figure 1 Four rollers 10 are installed at the bottom of the frame 18 to facilitate workers to move the frame 18.

[0032] Please refer to the attached drawings in the manual Figure 1 、 Figure 4 and Figure 5A positioning slot 17 is provided on the frame 18. A filter box 19 with an upper opening is placed in the positioning slot 17. A filter basket 13 with an upper opening is placed in the filter box 19. The sidewalls and bottom of the filter basket 13 are provided with a plurality of filter holes. Four straps 14 are formed at the opening of the filter basket 13. The straps 14 can be attached to the end surfaces of the opening of the filter box 19 to fix the filter basket 13 in a horizontal position relative to the filter box 19. The filter basket 13 is used to filter particles that are less than or equal to the standard particle size. The filter basket 13 is hinged with a cover 15, and a resilient hook 16 is detachably mounted on the cover 15. The cover 15 can close the opening of the filter basket 13 to prevent particles from leaving the filter basket 13. The resilient hook 16 has a certain elasticity and can hook into the filter holes of the filter basket 13. The cover 15 can close the opening of the filter basket 13 and fix its position relative to the filter basket 13. When particles larger than the standard particle size are distributed on the inner wall of the filter basket 13, if the discharge port 12 continues to discharge material, particles smaller than or equal to the standard particle size will be laid above the particles larger than the standard particle size. At this time, the worker can cover the filter basket 13 with the cover 15, remove the strap 14 from the filter box 19, and then manually shake the filter basket 13 to improve the particle distribution in the filter basket 13, so that particles smaller than or equal to the standard particle size in the filter basket 13 can pass through the filter basket 13 and enter the filter box 19. The positioning groove 17 can locate the position of the filter box 19 so that the filter box 19 can accurately receive the particles discharged from the discharge port 12. When the cover 15 needs to be rotated, a thin rod or other object can be used to poke the elastic hook 16 out of the filter hole and then rotate the cover 15.

[0033] The working principle of this embodiment is as follows: first, the powder and the adhesive are poured into the material cylinder 1, and then the stirring paddle 2 stirs the powder and the adhesive evenly, the cutting tool 4 rotates to cut the material, and then the motor 3 6 drives the material cylinder 1 to rotate a certain angle so that the bottom surface of the material cylinder 1 is tilted, the filter box 19 is placed in the positioning groove 17, and then the block 7 is moved away from the discharge port 12, and the particles can enter the filter basket 13 for filtration.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
