In the prior art, the photoelectric eye structure for correcting the position of the color mark on the packaging machine has various structures, and most of the photoelectric eyes have a photoelectric transmitting tube and a photoelectric receiving tube on the probe, and the circuit board matched with the same is also provided. One analog analog signal output or switch signal output, the photoelectric receiving tube realizes the correction control according to the color depth of the color standard to change the photoelectric eye output signal. Since the photoelectric eye has only one photoelectric transmitting tube, the photoelectric receiving tube also receives There is only one signal, and there is no comparable value, so the photoelectric eye can only detect the change of the color mark and cannot detect the offset and the offset direction of the excellent target. When the photoelectric eye is applied to the correction control, it can only rely on artificial After setting the reference value of the target color in advance, it compares with the output signal of the photoelectric eye to dynamically search for the color mark rectification. Since it relies on the dynamic search for the color mark to maintain the correction, it has large vibration, high noise and corrective deviation during operation. Low disadvantages. How to solve such a problem of poor stability and accuracy of the photoelectric eye is a difficult problem that a person skilled in the art has been trying to solve and is difficult to solve.
