The screening assembly includes a guide rod 14 fixedly installed between the top and bottom of the inner wall of the screening box 1, and the outer surfaces of the two guide rods 14 are movably sleeved with guide rings 15, and an inclined frame 16 is fixedly connected between the two guide rings 15. A screening net 17 is embedded in the bottom of the inner wall of the inclined frame 16, and a striking plate 19 is fixedly connected to the bottom of the inclined frame 16. A spring 18 is provided between the guide ring 15 and the top of the inner wall of the screening box 1 and on the outer surface of the guide rod 14.

One end of the guide inclined plate 2 passes through the second discharge port 11 and extends to the outside of the screening box 1 , and baffles are fixedly connected to the front and back sides of the guide inclined plate 2 and located outside the screening box 1 .

The driving assembly includes a fixing seat 20 fixedly mounted on the top of the guide inclined plate 2, a driving motor 21 is fixedly mounted on the top of the fixing seat 20, and a cam 22 is fixedly connected to the output end of the driving motor 21.

The air suction assembly includes a motor bracket 23 fixedly mounted inside the air cylinder 3, a driving motor 24 fixedly mounted on the motor bracket 23, a rotating shaft 25 fixedly connected to the output end of the driving motor 24, a fan blade 26 is provided on the outer surface of the rotating shaft 25, a cleaning brush 5 fixedly mounted on the rotating shaft 25, and the cleaning brush 5 abuts against the filter plate 4.

The collecting assembly comprises a fixed box 27 fixedly connected to the bottom end of the dust exhaust pipe 9, a collecting frame 28 is movably inserted on the front of the fixed box 27, and a handle is fixedly installed on the front of the collecting frame 28.

Working principle: When working, first turn on the driving motor 1 21 and the driving motor 2 24 through the control switch 13, then pour the tobacco to be screened from the feed hopper 12 into the screening box 1, and the tobacco falls into the inclined frame 16. The tobacco fragments are screened through the screening net 17 in the inclined frame 16, and the tobacco fragments pass through the mesh of the screening net 17 and fall on the guide inclined plate 2, and the tobacco fragments are guided to the discharge port 2 11 through the guide inclined plate 2 to be discharged from the screening box 1, and the tobacco intercepted by the screening net 17 is discharged from the screening box 1 from the discharge port 10, thereby realizing the screening of the fragments in the tobacco to improve the quality of the tobacco;

When screening the tobacco, the output end of the driving motor 21 is rotated to drive the cam 22 to rotate. When the cam 22 rotates to abut against the striking plate 19, the cam 22 pushes the striking plate 19 and the inclined frame 16 to move up. The setting of the guide rod 14 and the guide ring 15 can limit the inclined frame 16, which can improve the stability of the inclined frame 16 when it moves up and down. When the inclined frame 16 moves up, the guide ring 15 moves up synchronously, squeezing the spring 18 to make it in a compressed state and store energy. When the cam 22 rotates to disengage from the striking plate 19, the elastic force of the spring 18 and the gravity of the inclined frame 16 itself will make the inclined frame 16 quickly move down and reset, so that during the continuous rotation of the cam 22, the inclined frame 16 will be driven to shake back and forth up and down, thereby avoiding the accumulation of tobacco on the screening net 17, which will cause the screening net 17 to be blocked, and the screening efficiency of the screening net 17 for tobacco can be improved.

In the process of tobacco screening, dust is inevitably generated. The output end of the driving motor 24 is rotated to drive the rotating shaft 25 to rotate, thereby driving the fan blades 26 and the cleaning brush 5 to rotate synchronously. The rotation of the fan blades 26 can blow the gas in the air cylinder 3 outward, so that the air cylinder 3 is in a negative pressure state, so that the dust generated in the process of tobacco screening in the screening box 1 can be sucked into the air cylinder 3 through the coordinated use of the dust collecting hood 8, the dust suction pipe 7 and the collection box 6. At the same time, the gas in the screening box 1 is extracted, so that the screening box 1 is also in a negative pressure state, so that the gas flow direction at the inlet and outlet on the screening box 1 can only be toward the inside of the screening box 1, and cannot be reversed. It can prevent dust from diffusing from the inlet and outlet on the screening box 1 to the outside of the screening box 1, and prevent the working environment from being polluted by dust;

The dust can be filtered and intercepted by setting the filter plate 4 in the air duct 3, and the dust adsorbed on the filter plate 4 can be brushed off by the rotating cleaning brush 5. The brushed off dust falls into the collecting frame 28 through the dust exhaust pipe 9 for unified collection. When it is necessary to clean the dust collected in the collecting frame 28, the worker first turns off the driving motor 24, and then pulls the collecting frame 28 out of the fixed box 27 through the handle, and the dust collected in the collecting frame 28 can be cleaned. The operation is simple and convenient.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
