Pressure-equalizing precise air knife with wavy air outlet

The utility model discloses a wave-shaped air outlet pressure-equalizing precision air knife which comprises an air knife body and side sealing plates, the side sealing plates are arranged at the two ends of the air knife body, an air outlet nozzle is arranged on the air knife body, a linear air outlet is formed in the middle of the air outlet nozzle, and a first wave piece and a second wave piece are arranged in the linear air outlet. The opposite inner side faces of the first wave piece and the second wave piece are respectively provided with a wave-shaped concave-convex face, the convex positions of the concave-convex face of the first wave piece correspond to the convex positions of the concave-convex face of the second wave piece in position, and the concave positions of the concave-convex face of the first wave piece correspond to the concave positions of the concave-convex face of the second wave piece in position. And therefore, a plurality of air outlet holes which are uniformly arranged and are perp
