In this embodiment, the lower blowing pipe 1 is a hollow metal square pipe with a rectangular or square cross section, in other embodiments, the cross section of the lower blowing pipe 1 may be other shapes, and only the top of the lower blowing pipe 1 needs to be set to be a flat plate, for example, the cross section may be semicircular, rounded rectangle, etc. The first limit baffle 2 and the second limit baffle 3 are respectively arranged at the left side and the right side of the lower air blowing flat plate 11, and the first limit baffle 2, the second limit baffle 3 and the lower air blowing flat plate 11 jointly surround to form a conveying groove. When the caps 4 are conveyed, the caps 4 can be placed in the conveying groove, and the caps 4 move forwards along the conveying groove under the driving force of the airflow, so that the function of conveying the caps 4 is realized. The lower blowing flat plate 11 is provided with a first inclined blowing hole 111, and the lower blowing pipe 1 is communicated with the outside through the first inclined blowing hole 111. The inclined direction of the first inclined blowing hole 111 is the same as the outlet direction of the conveying trough, as shown in fig. 1, the first inclined blowing hole 111 is inclined to the right side, and similarly, the cap 4 is output from the right end of the conveying trough. When the air blowing device is used, air is blown into the downward air blowing pipe 1, so that the air pressure in the downward air blowing pipe 1 is larger than the external air pressure, and the air flow is blown out along the first oblique air blowing hole 111 to form oblique air flow. The oblique air flow acting on the caps 4 is divided into a vertical upward component and a horizontal rightward component, the vertical upward component is used for supporting the caps 4 for a certain distance, and the caps 4 can be prevented from being worn or polluted due to strong friction with the bottom of the conveying groove (namely the upper surface of the lower blowing flat plate 11) in the conveying process. The horizontal component force acts on the cap 4 to drive the cap 4 to slide rightwards, and finally the cap 4 is separated from the right end of the conveying groove and conveyed to a destination to receive the next process of adding the cap 4.

In the present embodiment, the side of the cap 4 for covering (i.e., the side for covering with the tube or the like) faces the lower blowing plate 11. Because the face of the cap 4 used for covering is provided with the accommodating groove used for accommodating the bottle mouth and the pipe orifice, the oblique air flow blown out from the first oblique air blowing hole 111 directly blows into the accommodating groove, can directly act on the cap 4, and better utilizes the acting force of the oblique air flow.
