An air inlet flow channel is arranged between the wind guide plate and the upper cover plate, and the air inlet flow channel is conducted from the outside to the inside of the annular air knife body. The wind guide plate extends a flow guiding block from the air inlet flow channel to the through hole. One side of the flow guiding block is a curved surface, and the other side is a flat surface. The thickness of the flow guiding block gradually thins from the air inlet flow channel to the through hole.

[0006] Among them, the inclination angle of the curved surface is 20-50°.

The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0018] Such as Figure 1 and Figure 2As shown in the figure, an annular static elimination and dust removal ion air knife according to this embodiment includes an annular air knife body 1 and an ion nozzle 2. The annular air knife body 1 is hollow and penetrated with a through hole 11. The annular air knife body 1 includes an upper cover plate 21, a wind guiding plate 22 and a bottom plate 23 arranged in sequence. The ion nozzle 2 is located on one side of the bottom plate 23 and is arranged towards the center of the annular air knife body 1. An air inlet flow channel 24 is provided between the wind guiding plate 22 and the upper cover plate 21. The air inlet flow channel 24 is conducted from the outside to the inside of the annular air knife body 1. The wind guiding plate 22 extends from the air inlet flow channel 24 to the through hole 11 with a flow guiding block 221. One side of the flow guiding block 221 is a curved surface, and the other side is a flat surface. The thickness of the flow guiding block 221 gradually thins from the air inlet flow channel 24 to the through hole 11.

[0019] As Figure 1 and Figure 2 shown in the figure, the annular static elimination and dust removal ion air knife of this embodiment is annularly arranged. The product to be subjected to static elimination and dust removal is passed through the middle through hole 11, so that the annular static elimination and dust removal ion air knife is arranged around the product 360 degrees, which can perform a more comprehensive and cleaner treatment on the product without rotating the product, and the operation is more convenient. The annular static elimination and dust removal ion air knife of the present utility model includes an annular air knife body 1 and an ion nozzle 2. The annular air knife body 1 can eject high-speed gas to perform dust removal and cleaning treatment on the surface of the product, and the ion nozzle 2 can ionize air into positively charged ion groups and negatively charged ion groups, and simultaneously perform static elimination treatment on the product.

[0020] As Figure 1 and Figure 2 shown in the figure, the annular air knife body 1 is hollow and penetrated with a through hole 11, which is convenient for the product to extend into the through hole 11 for static elimination and dust removal.

The ion nozzle 2 ejects ion groups, and the ion groups are ejected onto the surface of the product under the action of the high-speed gas in the spraying direction, so as to perform static elimination and dust removal on the product. Specifically, an air inlet flow channel 24 is provided between the upper cover plate 21 and the wind guiding plate 22. The air inlet flow channel 24 is conducted from the outside to the inside of the annular air knife body 1. Moreover, the wind guiding plate 22 extends from the air inlet flow channel 24 to the through hole 11 with a flow guiding block 221. One side of the flow guiding block 221 is a curved surface, and the other side is a flat surface. The thickness of the flow guiding block 221 gradually thins from the air inlet flow channel 24 to the through hole 11, so that from the air inlet flow channel 24.

[0021] Preferably, the inclination angle of the curved surface is 20~50°. Specifically, the inclination angle of the curved surface can be 20°, 23°, 25°, 27°, 29°, 30°, 33°, 35°, 38°, 40°, 42°, 45°, 48°, 50°.
