The plate body is provided with a first air outlet, a second air outlet, a first air inlet 1101 and a second air inlet 1102. The first air outlet is communicated with the first air inlet 1101 through a first channel, and the second air outlet is communicated with the second air inlet 1102 through a second channel. Air nozzles 3 are installed on both the first air outlet and the second air outlet. Control valves 4 are arranged in both the first air inlet 1101 and the second air inlet 1102. Connecting pipes 2 are arranged on both the first air inlet 1101 and the second air inlet 1102.

[0021] In this kind of air knife tooling, a first air inlet 1101, a first air outlet, a second air inlet 1102 and a second air outlet are opened on the plate body. The first air inlet 1101 is communicated with the first air outlet through a first channel, and the second air inlet 1102 is communicated with the second air outlet through a second channel. An independent air passage is formed between the first air inlet 1101 and the first air outlet, and another independent air passage is formed between the second air outlet and the second air inlet 1102. The two air passages are in a completely independent state. Control valves 4 are installed on both the first air inlet 1101 and the second air inlet 1102, and air nozzles 3 are arranged on both the first air outlet and the second air outlet. The gas first enters the air passage from the control valve 4 and then leaves from the air nozzle 3, thus forming an air knife. So there are a total of 2 air knives in this kind of tooling.

[0022] In this kind of air knife tooling, two air passages are formed between the first air inlet 1101 and the first air outlet and between the second air outlet and the second air inlet 1102. The two air passages are in a completely independent state, and the air pressure of each air passage can be independently regulated.
