A rotating disk 14 is rotatably installed inside the cleaning chamber 2. Two filter plates 4 opposite to each other with respect to the midpoint of the rotating disk 14 are fixedly installed inside the rotating disk 14. One end of the exhaust pipe 1 close to the rotating disk 14 is provided with an opening. One end of the rotating disk 14 is arranged inside the opening and is slidably connected with the exhaust pipe 1. The two filter plates 4 are matched with the exhaust pipe 1. A rotating rod 7 is fixedly installed on one end surface of the rotating disk 14. One end of the rotating rod 7 in the length direction is rotatably connected with the inner wall of the cleaning chamber 2. A bevel gear set 6 is fixedly installed on the outer surface of the rotating rod 7. An intermittent mechanism 5 is fixedly installed at one end of the bevel gear set 6. A cleaning brush 9 is fixedly installed at one end of the intermittent mechanism 5 close to the rotating disk 14. The cleaning brush 9 corresponds to the filter plate 4. A dust-proof net 8 is fixedly installed on one end surface of the cleaning chamber 2 close to the rotating disk 14. By driving the baffle 502 and the arc teeth 503 to rotate through the rotating frame 501, when the rotating frame 501 rotates 360 degrees, the baffle 502 will drive the special-shaped gear 504 to rotate through the stop post 505. At this time, the arc teeth 503 are meshed with the special-shaped gear 504, and at the same time drive the special-shaped gear 504 to rotate 180 degrees, thereby driving the first bevel gear 601 to rotate 180 degrees, so that the first bevel gear 601 drives the second bevel gear 602 to rotate, so that the second bevel gear 602 drives the rotating rod 7 to rotate, and then drives the rotating disk 14 to rotate 180 degrees, so that the two filter plates 4 can be used alternately. And because when the rotating frame 501 rotates 360 degrees, the rotating disk 14 rotates 180 degrees, that is, the cleaning brush 9 fixedly connected with the rotating frame 501 can rotate to clean the filter plate 4, so that the device can conveniently clean the filter plate 4 rotated by the rotating disk 14, avoiding the need to frequently replace the filter plate 4 during use.

[0027] Among them, the intermittent mechanism 5 includes a rotating frame 501. An arc-shaped tooth 503 is provided on the outer wall of the rotating frame 501. A baffle 502 is fixedly installed on one end face of the rotating frame 501 close to the arc-shaped tooth 503. A special-shaped gear 504 is slidably installed on one end face of the rotating frame 501. The tooth surface of the special-shaped gear 504 corresponds to the arc-shaped tooth 503. Two retaining posts 505 are fixedly installed on one end face of the special-shaped gear 504. The two baffles 502 correspond to the retaining posts 505.

The rotating frame 501 is fixedly installed with the cleaning brush 9. The output end of the driving motor 15 drives the rotating frame 501 to rotate, so that the rotating frame 501 drives the baffle 502 and the arc-shaped tooth 503 to rotate. When the rotating frame 501 rotates 360 degrees, the baffle 502 will drive the special-shaped gear 504 to rotate through the retaining post 505. At this time, the arc-shaped tooth 503 is meshed with the special-shaped gear 504, and at the same time drives the special-shaped gear 504 to rotate 180 degrees, thereby driving the first bevel gear 601 to rotate 180 degrees, so that the first bevel gear 601 drives the second bevel gear 602 to rotate, so that the second bevel gear 602 drives the rotating rod 7 to rotate. Furthermore, when the rotating frame 501 continues to rotate, the rotating disk 14 can be continuously driven to perform intermittent 180-degree rotation, so that the two filter plates 4 can be used alternately. In the production of the device, the special-shaped gear 504 is preset, that is, when the rotating frame 501 rotates 360 degrees, the driven special-shaped gear 504 will rotate 180 degrees.

[0028] Among them, the bevel gear set 6 includes a first bevel gear 601 and a second bevel gear 602. The first bevel gear 601 is fixedly connected to the special-shaped gear 504. The second bevel gear 602 is fixedly connected to the rotating rod 7, and the first bevel gear 601 and the second bevel gear 602 are meshed with each other. By setting the bevel gear set 6, when the rotating frame 501 continues to rotate, the rotating disk 14 can be continuously driven to perform intermittent 180-degree rotation.

[0032] The working principle of this embodiment:

[0033] For a waste gas extraction and exhaust device for soft plastic production of the present utility model, during actual use, when the waste gas is discharged from the exhaust pipe 1, the waste gas passes through the filter plate 4. The filter plate 4 can filter large particle impurities in the waste gas. Then, the driving motor 15 is started, so that the output end of the driving motor 15 drives the rotating frame 501 to rotate, causing the rotating frame 501 to drive the baffle 502 and the arc-shaped teeth 503 to rotate. When the rotating frame 501 rotates 360 degrees, the baffle 502 will drive the special-shaped gear 504 to rotate through the stop post 505. At this time, the arc-shaped teeth 503 are meshed with the special-shaped gear 504, and at the same time drive the special-shaped gear 504 to rotate 180 degrees, thereby driving the first bevel gear 601 to rotate 180 degrees, causing the first bevel gear 601 to drive the second bevel gear 602 to rotate, so that the second bevel gear 602 drives the rotating rod 7 to rotate. Furthermore, when the rotating frame 501 continues to rotate, it can continuously drive the rotating disk 14 to perform intermittent 180-degree rotations, enabling the two filter plates 4 to be alternately used. And because when the rotating frame 501 rotates 360 degrees, the cleaning brush 9 fixedly connected to the rotating frame 501 also rotates 360 degrees, while the rotating disk 14 rotates 180 degrees, that is, the cleaning brush 9 can continuously rotate to clean the filter plate 4, so that the device can conveniently clean the filter plate 4 rotated by the rotating disk 14, avoiding the need to frequently replace the filter plate 4 during use. At the same time, the blower 12 is started, so that the blower 12 blows air to the outside of the rotating disk 14, enabling the device to collect the large particle impurities swept by the cleaning brush 9 into the ventilation dust collection frame 11, facilitating the cleaning of the impurities generated by the cleaning.
