[0023] See also Figure 1-5A feeding mechanism for a rotary tablet press includes a base 1, with a turntable 2 inserted in the middle of the upper end of the base 1. The turntable 2 consists of a disc structure and a round rod structure. The disc structure has a plurality of circular through holes 1 evenly distributed in an annular pattern. The through holes 1 are provided with a forming mold inside the through holes 1. The round rod structure is inserted with an upper pressure plate 4, a lower pressure plate 3, and the base 1. The lower pressure plate 3 is inserted between the lower end of the turntable 2 and the base 1. The upper pressure plate 4 is inserted at the upper end of the turntable 2. The lower pressure plate 3 and the upper pressure plate 4 are fixedly installed with a number of pressure heads 5 on the opposite sides. The pressure heads 5 correspond to the positions of the through holes one by one. The materials are pressed into sheets in the forming mold of the turntable 2 through the pressure heads 5 on the upper pressure plate 4 and the lower pressure plate 3. A holder 6 is fixedly installed on the left and right ends of the upper surface of the base 1. The function of the holder 6 is to make the telescopic rod 7 only move left and right, and to keep the reflux outer ring 8 and the crescent-shaped grid feeder 9 above it stationary when the turntable 2 is rotated for tableting. The turntable 2 rotates, and the material enters the reflux outer ring 8 through the funnel 12. Then, the material is concentrated in the middle of the V-shaped structure through the rotation of the turntable 2. The material is evenly distributed in each crescent-shaped grid feeder 9 through the through hole 2. The holder 6 is sleeved with the telescopic rod 7. The telescopic rod 7 is a convex structure, and one end of the big head is clamped on the side of the holder 6 away from the turntable 2. A reflux outer ring 8 is fixedly installed at one end of the telescopic rod 7 close to the turntable 2. The reflux outer ring 8 is a ring structure with a special through-hole structure in the middle. The function of the reflux outer ring 8 is to allow the material to circulate inside the reflux outer ring 8 through the forward and reverse rotation of the turntable 2, effectively preventing the waste of raw materials. A crescent-shaped grid feeder 9 is fixedly installed inside each reflux outer ring 8. The crescent-shaped grid feeder 9 is composed of several V-shaped structures and circular arcs on both sides of the V-shaped structure, and a through-hole 2 is opened in the middle of the V-shaped structure. When the turntable 2 is rotated, the material is concentrated in the middle of the V-shaped structure, so that the material quickly falls into the forming mold of the through hole 1 by gravity, and is formed into sheets by the impact of the upper and lower pressure heads 5. A bracket 10 is fixedly installed on the front end of the upper surface of the base 1. A cylinder is provided in the middle of the bracket 10. The upper end of the cylinder is clamped with a shaft sleeve 11 and the upper end of the bracket 10 is plugged with a shaft sleeve 11. A funnel 12 is fixedly installed at the end of the shaft sleeve 11 close to the turntable 2. The funnel 12 is an internal hollow structure. The funnel 12 consists of a storage structure at the upper end and two transport structures at the lower end. The lower end opening of each transport structure is just above the corresponding reflux outer ring 8. A spiral rod 13 is sleeved inside the funnel 12, and a fixing frame 14 is fixed to the upper end of the funnel 12. The fixing frame 14 is a cross-shaped structure, and a through hole 3 is opened in the middle. The through hole is circular. The lower end of the spiral rod 13 is a spiral structure, which is plugged into the bottom of the funnel 12 , and the upper end is plugged into the fixing frame 14 through the through hole 3 . A handle 15 is fixedly installed on the top of the spiral rod 13 .The complete loading steps are to add material into the funnel 12, and then by turning the handle, since the lower end of the handle is connected to a spiral structure, when the spiral structure is rotated, the material passes through the spiral structure in an orderly and uniform manner into the two transport structures below the funnel 12, and then falls into the inside of the reflux outer ring 8, and then by rotating the disc clockwise, the material causes the clockwise rotation on the reflux outer ring 8, and then by rotating it, it is evenly distributed inside the reflux outer ring 8, and then by rotating it counterclockwise, it drives the material to rotate counterclockwise so that the material is concentrated in the middle of the V-shaped structure, and the through hole 2 is just at the upper end of the through hole 1, so that the accumulated material enters the through hole 1 in an orderly manner to complete the tableting, and at the same time, by turning the handle 15, the material can be loaded and unloaded at any time, and then by plugging the bracket 10 and the shaft sleeve 11, the funnel 12 can be rotated to make it close to and away from the working stamping device, effectively ensuring the timeliness of loading, and this structure ensures that the material is evenly loaded and no material is wasted.

[0024] In summary, the feeding mechanism of the rotary tablet press effectively prevents the leakage of raw materials from the edge of the turntable 2 by providing a reflux outer ring 8 and a crescent-shaped grid feeder 9, and allows the raw materials to reflux through the forward and reverse rotation of the turntable 2. The V-shaped structure concentrates the raw materials above the through hole 1 opened in the turntable 2, ensuring accurate feeding of the raw materials.

[0025] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
