[0043] The working principle of the air flotation feeder of the utility model is:

[0044] First, adjust the width of the limit zone and the height of the two knobs 44 according to the width and thickness of the material belt to be conveyed, and determine the maximum height that the cylinder body 41 can rise. Before conveying the material belt, under the push of air pressure, the cylinder bodies 41 of the two cylinders move upward and press against the knob 44 before stopping to rise. Start the servo motor, and the first roller 21 starts to rotate. The material belt slides from the feed side through the first guide plate 3 and the third guide plate 8 into the feed gap. The material belt is pushed forward by the friction force of the first roller 21 and the second roller 42 in the feed gap, and enters the next workstation from the discharge side.
