[0021] The screening mechanism 10 includes a first rotating groove 1001, a second rotating groove 1002, a first connecting frame 1003, a ball 1004, a card slot 1005, a first support plate 1006, a first fixing frame 1007, a second connecting frame 1008, a second support plate 1009, a second fixing frame 1010, a connecting shaft 1011 and a rotating blade 1012. A first rotating groove 1001 is provided on one side surface of the housing 3, and a second rotating groove 1002 is provided on one side surface of the housing 3. The first connecting frame 1003 is arranged inside the first rotating groove 1001. A ball 1004 is arranged on one side surface of the first connecting frame 1003. A card slot 1005 is provided on one side surface of the first connecting frame 1003. The first support plate 1006 is arranged inside the card slot 1005. The first fixing frame 1007 is arranged on one side surface of the first support plate 1006. The second connecting frame 1008 is arranged inside the second rotating groove 1002. The second support plate 1009 is arranged on one side surface of the second connecting frame 1008. The second fixing frame 1010 is arranged on one side surface of the second support plate 1009. A connecting shaft 1011 is fixedly connected to one side surface of the motor 2. A rotating blade 1012 is fixedly connected to the outer side surface of the connecting shaft 1011. Through the arrangement of the first rotating groove 1001, the second rotating groove 1002, the first connecting frame 1003, the ball 1004, the card slot 1005, the first support plate 1006, the first fixing frame 1007, the second connecting frame 1008, the second support plate 1009, the second fixing frame 1010, the connecting shaft 1011 and the rotating blade 1012, when screening is required, first start the motor 2, and then the motor 2 drives the connecting shaft 1011 to rotate. When the connecting shaft 1011 rotates, it will drive the rotating blade 1012 to rotate, so as to convey and stir the gypsum powder, and break the lumpy powder in the gypsum powder. At this time, the second fixing frame 1010 will rotate under the rotation of the connecting shaft 1011. At the same time, the second support plate 1009, the second connecting frame 1008, the first fixing frame 1007, the first support plate 1006 and the first connecting frame 1003 rotate. At this time, the first connecting frame 1003 and the second connecting frame 1008 rotate inside the first rotating groove 1001 and the second rotating groove 1002 respectively, and the ball 1004 rotates inside it, so as to reduce friction and make the rotation of the screen frame smoother. At this time, due to the stirring of the rotating blade 1012 and the rotation of the screen, the gypsum powder can be screened. Through the arrangement of the second support plate 1009, the first screening will be carried out. The rotation of the second support plate 1009 drives the screen to carry out the second screening. When the screen needs to be replaced, first disassemble the housing 3, and then disassemble the first connecting frame 1003, the first support plate 1006, the first fixing frame 1007, the second connecting frame 1008, the second support plate 1009 and the second fixing frame 1010. Then replace the screen, clip the screen into the card slot 1005 and install it.

[0022] Further, a feeding port 4 is provided on one side surface of the outer shell 3, and a disassembly door 5 is threadedly connected to one side surface of the outer shell 3.

[0023] Further, a fine discharge port 6 is provided on one side surface of the outer shell 3, and a coarse discharge port 7 is provided on one side surface of the outer shell 3. Through the settings of the outer shell 3 and the fine discharge port 6, the gypsum powder after secondary screening can be discharged through the fine discharge port 6. Through the settings of the outer shell 3 and the coarse discharge port 7, the coarser gypsum material is discharged from the coarse discharge port 7.

[0024] Further, the first fixing frame 1007 and the second support plate 1009 are fixedly connected, and six groups of card slots 1005 are provided on the first connecting frame 1003, the first fixing frame 1007, the second connecting frame 1008 and the second fixing frame 1010 respectively. Through the settings of the first fixing frame 1007 and the second support plate 1009, when the connecting shaft 1011 rotates, it will drive the first fixing frame 1007 to rotate, so as to perform secondary screening.

[0025] Further, the anti-blocking mechanism 11 includes a baffle 1101, a through groove 1102, a rubber ring 1103, and a separation net 1104. The baffle 1101 is fixedly connected to the inner side of the outer shell 3. A through groove 1102 is provided on one side surface of the baffle 1101. A rubber ring 1103 is provided on the inner surface of the through groove 1102. The separation net 1104 is fixedly connected to the inner surface of the connecting shell 8. Through the settings of the baffle 1101, the rubber ring 1102, the through groove 1103, and the separation net 1104, when the motor 2 drives the connecting shaft 1011 to rotate, through the settings of the baffle 1101 and the rubber ring 1103, the powder can be prevented from entering the motor 2, so that the phenomenon of blocking the motor 2 and jamming will not occur. And the setting of the separation net 1104 can prevent a large amount of dust from adhering to the wind wheel 9 and causing it to malfunction.

[0026] Further, the rubber ring 1103 is wrapped around the outer surface of the connecting shaft 1011, and the baffle 1101 is designed in a groove shape. Through the settings of the rubber ring 1103 and the connecting shaft 1011, the connecting shaft 1011 can rotate better, and at the same time, the dust is prevented from entering the motor 2. Through the setting of the baffle 1101, the rotary blade 1012 can rotate better without being hindered.

[0027] Working principle: First, when it is necessary to screen gypsum powder, pour the gypsum powder from the feeding port 4, then start the motor 2, and then the motor 2 drives the connecting shaft 1011 to rotate. When the connecting shaft 1011 rotates, it will drive the rotating blade 1012 to rotate, so as to convey and stir the gypsum powder. At this time, the second fixing frame 1010 will rotate under the rotation of the connecting shaft 1011. At the same time, the second support plate 1009, the second connecting frame 1008, the first fixing frame 1007, the first support plate 1006 and the first connecting frame 1003 rotate. At this time, the first connecting frame 1003 and the second connecting frame 1008 rotate inside the first rotating groove 1001 and the second rotating groove 1002 respectively, and the ball 1004 rotates inside them. At this time, due to the stirring of the rotating blade 1012 and the rotation of the sieve mesh, the gypsum powder can be screened. Through the setting of the second support plate 1009, the first screening will be carried out. The rotation of the second support plate 1009 drives the sieve mesh to carry out the second screening. At this time, the wind wheel 9 rotates to push the gypsum powder inward. The finer gypsum powder will flow into the fine discharge port 6 through the secondary screening, and the coarser gypsum powder will flow into the coarse discharge port 7 under the drive of the wind wheel 9.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
