[0012] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] like Figures 1 to 3 As shown, this utility model embodiment includes a base 1, a pressing knife 2, a main shaft 11, and a hollow shaft 12. The hollow shaft 12 is connected in the middle of the base 1. The pressing knife 2 is connected to the main shaft 1 that passes through the hollow shaft 12, and is used to drive the base 1 and the pressing knife 2 to rotate in opposite directions. Several granulation knife seats 3 are evenly distributed around the edge of the base 1. The outer side of the granulation knife seat 3 is arc-shaped and is provided with granulation blades 4 that fit against it, which are used to cooperate with the screen 10 and the pressing knife 2 on the rotary granulator to extrude and granulate the material.

[0015] During operation, material is fed into the pressing knife 2, and the main shaft 11 drives the pressing knife 2 to rotate. The pressing knife 2 brings the material into the extrusion angle of the granulating blade 4. The hollow shaft 12 drives the base 1 and the granulating blade 4 on it to rotate in the opposite direction. The granulating blade 4 then extrudes the material into the screen 10 to form a finished product.

[0016] Preferably, the top of the granulation blade holder 3 is provided with a pressing plate 6. The outer side of the pressing plate 6 is arc-shaped, which is used to work with the granulation blade 4 to squeeze the material. The size of the pressing plate 6 can be changed according to the material properties.

[0017] Preferably, the granulator holder 3 is fixedly connected to the base 1 by an internal hexagon screw 9 and is positioned by a cylindrical pin 8 to prevent deformation caused by welding the granulator holder 3 to the base 1. The number of granulators can be determined according to the customer's pharmaceutical process.

[0018] Preferably, the granulation blade 4 and the granulation blade holder 3 are fixedly connected by countersunk screws 5, which facilitates replacement and does not affect the contact between the granulation blade 4 and the material. The length of the granulation blade 4 can be adjusted according to the customer's pharmaceutical process, thereby adjusting the gap between it and the screen 10.

[0019] Preferably, the pressing plate 2 is fixedly connected to the granulation knife holder 3 by the plug screw 7. The pressing plate 2 and the granulation knife holder 3 can also be designed as an integral part to prevent the pressing plate 6 from moving and affecting the granulation operation.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
