[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: including a shell assembly 1, wherein a spiral conveying assembly 2 and a screening assembly 3 are disposed inside the shell assembly 1;

[0025] The outer shell assembly 1 includes a cylinder 101, a screening chamber 102 is provided inside the cylinder 101, an arc-shaped opening 106 is provided on one side of the back of the cylinder 101, an L-shaped fixing plate 107 is fixedly installed on the back of the cylinder 101 near the arc-shaped opening 106, and a cylinder 108 is fixedly installed on the back of the horizontal part of the L-shaped fixing plate 107.

[0026] The screening component 3 includes a screening outer cylinder 301, a circular opening 302 on one side of the top surface of the screening outer cylinder 301, an inner groove 303 on the front surface of the screening outer cylinder 301, a screening inner cylinder 304 movably inserted into the inner groove 303, an arc plate 305 fixedly installed on one side of the front surface of the screening inner cylinder 304, and several screening ports on the cylinder bodies of both the screening outer cylinder 301 and the screening inner cylinder 304.

[0027] The outer screening cylinder 301 is fixedly installed inside the screening chamber 102. One end of the arc-shaped plate 305 passes through the arc-shaped opening 106, and the end of the arc-shaped plate 305 passing through the arc-shaped opening 106 is fixedly connected to one end of the piston rod of the cylinder 108.

[0028] In this embodiment, a first discharge port 103 is provided on the back of the cylinder 101, and a second discharge port 105 is fixedly embedded on the bottom surface of the cylinder 101. Pills smaller than the screening opening of the screening outer cylinder 301 will fall out from the screening outer cylinder 301, thereby screening out pills that are not up to standard in size. Pills that are not up to standard in size will roll out from the second discharge port 105, and pills that are up to standard in size will be discharged from the first discharge port 103.

[0029] Meanwhile, the spiral conveying assembly 2 includes a rotating motor 201, with a rotating roller 202 fixedly mounted on one end of the output shaft of the rotating motor 201. A spiral blade 203 is fixedly sleeved on the roller body of the rotating roller 202. The rotating motor 201 is fixedly installed at the center of the front of the cylinder 101. The rotating roller 202 and the spiral blade 203 are located inside the outer screening cylinder 301, and the outer surface of the spiral blade 203 is in contact with the inner wall of the outer screening cylinder 301. The outer screening cylinder 301 has several screening openings, and the inner screening cylinder 3... The several screening ports on 04 correspond one-to-one. The rotation of the spiral blade 203 can transport the pills that enter the screening outer cylinder 301 towards the first discharge port 103. During the transportation process, the pills will roll in a spiral in the screening outer cylinder 301. Pills smaller than the screening port of the screening outer cylinder 301 will fall out of the screening outer cylinder 301, thus screening out pills that do not meet the size requirements. Pills that do not meet the size requirements will roll out from the second discharge port 105, and pills that meet the size requirements will be discharged from the first discharge port 103.

[0030] A feeding hopper 104 is provided at the rear of the top surface of the cylinder 101. The bottom end of the feeding hopper 104 passes through the circular opening 302 and is connected to the inside of the screening outer cylinder 301. In use, the pills are poured into the feeding hopper 104 and enter the screening outer cylinder 301. Then, the rotating motor 201 is started, which drives the rotating roller 202 to rotate. The rotation of the rotating roller 202 drives the spiral blade 203 to rotate. The rotation of the spiral blade 203 conveys the pills that have entered the screening outer cylinder 301 toward the first discharge port 103. During the conveying process, the pills will roll in a spiral in the screening outer cylinder 301. Pills smaller than the screening opening of the screening outer cylinder 301 will fall out of the screening outer cylinder 301, thus screening out pills that are not up to size. Pills that are not up to size will roll out from the second discharge port 105, and pills that are up to size will be discharged from the first discharge port 103.

[0031] Meanwhile, the size of the screening port of the screening component 3 can be adjusted according to the screening requirements. Specifically, the cylinder 108 is activated, and the arc plate 305 can move under the action of the cylinder 108. The movement of the arc plate 305 can control the movement of the inner screening cylinder 304. When the diameter of the screening port on the surface of the inner screening cylinder 304 is completely coincident with the diameter of the screening port of the outer screening cylinder 301, the diameter of the screening port of the outer screening cylinder 301 is at its maximum. When the inner screening cylinder 304 is slowly moved in the inner groove 303, the screening ports on the two cylinders can be changed from completely coincident to completely non-coincident. During this adjustment process, the diameter of the screening port of the outer screening cylinder 301 can be gradually reduced, so that the size of the port can be adjusted as needed. In this way, the screening of pills can be performed according to the actual pill screening requirements, making it more practical.

[0032] 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.
