[0024] Reference Figure 1-7 A pill grading and screening device comprises a base 1, a screen cage 2 is provided on the top of the base 1, a first fixing frame 3 and a second fixing frame 4 are fixedly installed on both sides of the screen cage 2 on the top of the base 1, a screening component 5 and a pouring component 6 are respectively provided in the first fixing frame 3 and the second fixing frame 4, the screening component 5 is used to rotate the screen cage 2, and the pouring component 6 is used to tilt the screen cage 2, a pair of guide plates 7 are also provided on the top of the base 1 below the screen cage 2, an inlet is provided at one end of the screen cage 2 close to the first fixing frame 3, a cover door 24 is hinged at the inlet of the screen cage 2, and the inlet is used to load pills.

[0025] The screen cage 2 includes a primary screen cage 21 and a secondary screen cage 22 . The primary screen cage 21 is fixedly connected to the secondary screen cage 22 , and the interiors of the two are communicated. An auger 23 is also fixedly installed in the screen cage 2 .

[0026] It should be noted that a through groove 221 is provided on the end face of the secondary screen cage 22. When the pills in the secondary screen cage 22 are larger than the through holes of the secondary screen cage 22, the pouring assembly 6 is used to tilt the screen cage 2 to discharge the pills inside through the through groove 221, so as to achieve the effect of three-level screening of pills.

[0027] Furthermore, the screening material assembly 5 includes a rotating seat 51, both ends of which are rotatably connected to the first fixed frame 3, and a first motor 52 is fixedly installed on the top of the rotating seat 51. The shaft end of the first motor 52 is fixedly connected to the end face of the primary screen cage 21. The first motor 52 can drive the screen cage 2 to rotate to achieve the purpose of screening pills.

[0028] Furthermore, the material pouring assembly 6 includes a rotating ring 61, which is sleeved on the outer periphery of one end of the secondary screen cage 22. The end face of the second fixed frame 4 is provided with an arc groove 41. The two ends of the rotating ring 61 are slidably connected in the arc groove 41. The rotating ring 61 cooperates with the first fixed frame 3 to fix the screen cage 2, and is also used to support the screen cage 2. A plurality of balls roll in the rotating ring 61 to reduce the friction between the ring body and the secondary screen cage 22.

[0029] In more detail, the top of the base 1 is located below the secondary screen cage 22 and a second motor 62 is fixedly installed thereon, a support plate 63 is fixedly installed on one side of the second motor 62, the shaft end of the second motor 62 passes through the support plate 63 and a connecting rod 64 is fixedly installed thereon, and the support plate 63 is used to support the shaft end of the second motor 62 and share the pressure on the shaft end.

[0030] In general, a round rod 65 is fixedly installed at the bottom of the rotating ring 61, and a ball ring 66 is slidably connected to the outer periphery of the round rod 65. The other side of the ball ring 66 is slidably connected to the other end of the connecting rod 64 through a straight rod 67. There are several balls inside the ball ring 66. The balls are used to reduce the friction between the ball ring 66 and the round rod 65 to prevent the connecting rod 64 from getting stuck.

[0031] Finally, a straight groove 11 is provided on the end face of the base 1, and support rods 71 ​​are fixedly installed on both sides of one end of the guide plate 7. The support rod 71 is slidably connected to the straight groove 11, and a spring 72 is sleeved on the outer periphery of the support rod 71. The two ends of the spring 72 respectively contact the top of the base 1 and the bottom of the guide plate 7. A nut 73 is threadedly connected to one end of the support rod 71 located at the bottom of the base 1. When the screen cage 2 is tilted by the pouring assembly 6, the guide plate 7 may be squeezed. The spring 72 and the support rod 71 are used to prevent the guide plate 7 from being stuck with the screen cage 2. When the rotation speed of the screen cage 2 is faster, more pills are discharged, and the nut 73 needs to be adjusted to change the angle of the guide plate 7 to transport the pills in accordance with the rotation speed of the screen cage 2, and the straight groove 11 is provided to prevent the support rod 71 from being stuck.

[0032] Working method: When working, the pills are poured into the primary screen cage 21 along the feeding port at the cover door 24, and the first motor 52 drives the screen cage 2 to rotate. The smaller pills fall into the guide plate 7 at the through hole of the primary screen cage 21, and then move toward the secondary screen cage 22 under the action of the auger 23. After that, the largest pills will stay in the secondary screen cage 22, and the shaft end of the second motor 62 drives the connecting rod 64 to drive the ball ring 66 to make one end of the secondary screen cage 22 tilt downward, and the largest pills roll out from the through groove 221 to achieve the effect of three-level screening. After that, the second motor 62 drives the secondary screen cage 22 back to its original position, and the angle of the guide plate 7 is changed by adjusting the nut 73 to cooperate with the rotation speed of the screen cage 2 to complete the screening of the pills.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
