Referring to fig. 1, 2 and 4, in some embodiments, the air guiding device 300 further includes a rack (not shown), where the first air duct 1, the second air duct 2 and the third air duct 3 are fixedly disposed.

In the utility model, the first air pipe 1 is provided with the plurality of ventilation openings 11, so that the plurality of second air pipes 2 are simultaneously communicated to the first air pipe 1, and the ventilation openings 11 are distributed along the circumferential direction of the first air pipe 1, so that the plurality of second air pipes 2 can ventilate into the first air pipe 1 at a plurality of positions in the circumferential direction of the first air pipe 1, the uniform distribution of air in the first air pipe 1 is improved, the uniform blowing of the workpiece 200 is realized, and the operation effect is improved. The first wind sections 21 of the second wind pipes 2 are communicated to the first wind pipes 1, and the included angle between the extending direction of each first wind section 21 and the extending direction of the first wind pipe 1 is a first included angle alpha, so that different wind directions of the second wind pipes 2 entering the first wind pipes 1 are the same, different wind pressures are avoided being brought in the direction perpendicular to the extending direction of the first wind pipes 1, wind can flow in the first wind pipes 1 along the same direction, uniform distribution of wind in the first wind pipes 1 is facilitated, uniform blowing of the workpieces 200 is achieved, and the operation effect is improved. The first included angle alpha is more than or equal to 10 degrees and less than or equal to 80 degrees, so that wind entering the first air pipe 1 from the plurality of second air pipes 2 can be down in order, the effect of equalizing pressure is achieved, and the operation effect is improved; if the first included angle α is greater than 80 °, after the air flows enter the first air duct 1 from the plurality of second air ducts 2, the air cannot clearly and uniformly flow in the extending direction of the first air duct 1, turbulence occurs to shake the workpiece 200, if the first included angle α is less than 10 °, the air pressure of the air flows in the extending direction perpendicular to the first air duct 1 is too small, the effect is very obvious, and the pressure difference is generated, and the plurality of second air ducts 2 simultaneously ventilate to cause uneven stress of the workpiece 200 to shake the workpiece 200.
