[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1:

[0020] The following is combined with Figure 1-3 This embodiment describes a high-efficiency wet granulator, comprising: a granulation chamber 1, the upper portion of the granulation chamber 1 being connected to a screw conveyor 2, the bottom wall of the screw conveyor 2 being provided with an extrusion hole 3, the granulation chamber 1 being provided with a rotating granulation disk 4, the upper surface of the granulation disk 4 being connected to a connecting shaft 5, the upper end of the connecting shaft 5 being connected to a cutter 6, the cutter 6 being in contact with the outer surface of the bottom wall of the screw conveyor 2;

[0021] The screw conveyor 2 extrude the raw materials through the extrusion hole 3, and the power of the granulation disk 4 is turned on. The granulation disk 4 drives the cutter 6 to rotate through the connecting shaft 5. The cutter 6 rotates at a constant speed to cut the uniformly extruded medicine into granules. The granules fall on the granulation disk 4, roll with the rotation of the granulation disk 4, and roll into pills. The pill making is completed and the granules will not be damaged.

[0022] The outside of the granulation chamber 1 is connected to a bracket 7, the lower part of the bracket 7 is connected to a chassis 8, an input shaft 9 is rotatably connected to the chassis 8, the upper part of the input shaft 9 is slidably connected to a sleeve 10, the sleeve 10 is connected to the bottom wall of the granulation disk 4, the granulation disk 4 can rotate and slide in the lower part of the granulation chamber 1, the lower surface of the granulation disk 4 is in contact with the upper part of the hydraulic cylinder 11, and the fixed end of the hydraulic cylinder 11 is connected to the upper surface of the chassis 8;

[0023] The granulating disc 4 is lifted and lowered by the extension and contraction of the hydraulic cylinder 11. The pills are discharged after the granulating disc 4 is lowered. The input shaft 9 slides in the sleeve 10 to ensure that the transmission is not disconnected.

[0024] The telescopic end of the hydraulic cylinder 11 is connected to a magnet 12, and a magnetic ball 13 is embedded in the magnet 12, and the magnetic ball 13 is in contact with the lower surface of the granulation disk 4;

[0025] The magnet 12 and the magnetic balls 13 generate suction force on the granulation disk 4 to prevent the granulation disk 4 from descending and getting stuck. When the granulation disk 4 rotates, the magnetic balls 13 reduce friction.

[0026] The inner wall of the granulation chamber 1 is rotatably connected to a rotating drum 14, and the lower end of the rotating drum 14 can contact the upper surface of the granulation disk 4;

[0027] When the granulating disk 4 contacts the lower end of the rotating drum 14, the power of the granulating disk 4 can be transmitted to the rotating drum 14 through friction, and the rotation of the rotating drum 14 makes the granules more round.
