How to adjust an automatic labeling machine:

1. The position of the detection eye for the object affects the timing of label output, so it must be adjusted properly. The required position varies with bottle sizes; if the detection eye is too far back, it can cause the label to be output too early, leading to premature labeling or even missing the label. Conversely, if the detection eye is too far forward, the label output will be delayed, causing misaligned or overly late labeling. (Front refers to the direction the operator faces the human-machine interface, with the bottle moving forward on the conveyor belt.) 2. The label detection eye is crucial for determining the label output position and pre-output length, so its position must also be adjusted correctly. The required position may vary for different labels; if the label detection eye is too high, it can result in insufficient pre-output, leading to inaccurate labeling or late labeling. If the label detection eye is too low, it can cause excessive pre-output, leading to皱皱的 labeling or early labeling.
