The second transmission gear 69 drives the air pipe 52 to rotate anticlockwise through the second one-way bearing 691, and the air pipe 52 drives the air guide valve 53 to rotate anticlockwise, so that the air outlet 531 is separated from the first ventilation cavity 541 in a rotating manner and is communicated with the inside of the second ventilation cavity 542. When the air delivery mechanism 5 is moved to approach the first reversing gear rack 61, the second air jet 555 delivers a spreading air stream to the fiber single web. So that the spreading air flow is always located above the fibre fleece being laid as the fibre fleece moves back and forth with the first rotation source 2.
When the air delivery mechanism 5 moves towards the position close to the second reversing rack 66 and moves to the end of the supporting frame 11 for reversing, if the first air jet pipe 554 still continues to deliver spreading air flow, the spreading air flow can increase the irregular moving distance of the fiber single net in the process of laying the fiber single net, which is not beneficial to the smooth spreading of the fiber single net on the material storage plate 1.
The rotating roller 3 moves synchronously with the air conveying mechanism 5, the rotating roller 3 reciprocates along the length direction of the supporting frame 11, on one hand, the fiber single net is folded and paved on the material storage plate 1, on the other hand, the first reversing gear 62 is meshed with the first reversing rack 61, the air outlet 531 rotates to be separated from the second air through cavity 542 and is communicated with the inside of the first air through cavity 541, the second reversing gear 67 is meshed with the second reversing rack 66, the air outlet 531 rotates to be separated from the first air through cavity 541 and is communicated with the inside of the second air through cavity 542, when the rotating roller 3 changes the moving direction, the reversing mechanism 6 can synchronously complete the replacement of different air spraying pipes for conveying and using spreading air flow, and when the fiber single net reciprocates along with the rotating roller 3, the spreading air flow is always positioned above the fiber single net being paved.
Referring to fig. 3 and 5, a plurality of air injection holes 551 are formed along the circumferential direction of the air injection tube body 55, and the plurality of air injection holes 551 are also formed along the length direction of the air injection tube body 55, the air injection holes 551 formed at both ends of the air injection tube body 55 are first air outlet holes 552 which are obliquely arranged, and the air injection holes 551 formed between the first air outlet holes 552 are second air outlet holes 553 formed along the radial direction of the air injection tube body 55.

The first rotating source 2 rotates forward and reversely to drive the two rotating rollers 3 to fold and lay the fiber single net on the storage plate 1.
In the process of laying the fiber single net, the air conveying mechanism 5 sprays spreading air flow on the fiber single net surface. Because the rotating roller 3 drives the fiber single net to reciprocate along the length direction of the supporting frame 11, when the rotating roller 3 drives the fiber single net to move towards the direction close to the first reversing rack 61, the fiber single net passing through the two rotating rollers 3 is located below the second material conveying roller 32, and at the moment, the air outlet 531 is communicated with the inside of the second ventilation cavity 542, so that the second air jet pipe 555 conveys spreading airflow to the fiber single net. When the rotating roller 3 moves in a direction approaching to the second reversing rack 66 in a reversing way, the first reversing rack 61 is meshed with the first reversing gear 62 to drive the air guide valve 53 to rotate, so that the air outlet 531 is separated from the second ventilation cavity 542 and is communicated with the inside of the first ventilation cavity 541, and the first air injection pipe 554 conveys spreading air flow to the fiber single net, so that the spreading air flow is always positioned above the fiber single net being paved.
