The invention discloses a vacuum compression bag air valve mounting system. The vacuum compression bag air valve mounting system comprises a roll wheel and a motor used for controlling the roll wheel. The roll wheel is used for conveying a cloth coil for manufacturing a compression bag. The vacuum compression bag air valve mounting system further comprises a vibration disc used for conveying a flaky valve body, a valve pressing mechanism, a mechanical hand and a hole puncher. The valve pressing mechanism comprises a hydraulic rod and an ejector rod, the ejector rod is located below the hydraulic rod, the upper portion of the ejector rod is used for containing the valve body, and the valve body and corresponding holes in the cloth coil are pressed. The mechanical hand is used for grabbing the valve body from the vibration disc and putting the valve body on the upper portion of the ejector rod. The hole puncher is used for punching the holes for pressing the valve body in the cloth coil. According to the vacuum compression bag air valve mounting system, automation of compression bag air valve mounting is achieved, arrangement and guard of workers are not needed, the system achieves hole punching and valve body pressing in place through one step, the production efficiency is improved, and the defective percentage is reduced.
