High-pressure air pipe connecting flange of adhesive tape air knife splitting machine

The invention discloses a high-pressure air pipe connecting flange of an adhesive tape air knife splitting machine. The high-pressure air pipe connecting flange comprises a disc-shaped bottom plate. A connecting neck protruding upwards is arranged at one end of the bottom plate, and a hollow through hole is formed in the middle of the connecting neck and penetrates the bottom plate. A key groove is formed in one end of the through groove. A plurality of connecting columns are fixed to the upper surface of the bottom plate and the outer side of the connecting neck. One included angle is formed between each connecting column and the connecting neck and is 34.29 degrees. The bottom plate is provided with a plurality of fixing holes. According to the flange, the through hole penetrates the bottom plate and the connecting neck, the multiple connecting columns are fixed to the upper surface of the bottom plate and the outer side of the connecting neck, and therefore the structural strength of the flange is improved
