1. The bottom paper is broken
The breakage of the backing paper is closely related to the quality of the label backing paper, the scratching of the backing paper in the label traction path, and the sticking of the label.

a. Check whether the backing paper is cut. If the backing paper is cut, you need to replace the high-quality backing paper. It is recommended to use glassine backing paper, and the label supplier is required to control the die-cutting depth so as not to damage the backing paper. the
b. Check for scratches in label wrapping and eliminate scratches. the
c. If the label sticks, the label is easy to tear. Control the length of the next label to ensure that it does not stick to the labeled product.
2. Labeling deviation exceeds 2mm
The label deviation is related to the deviation of the label tape, the direction of the label tape is not parallel to the product conveying direction, the traction wheel slips, the product positioning detection is inaccurate, the label is not attached to the product along the label covering roller, and the product error is related to several factors. Check the above several factors Factors, and then targeted to solve.
If the label tape deviates, loosen the traction mechanism, pull the label back and forth, and let it go straight automatically. After the label is aligned, clamp the limit rings on both sides to guide the label. the
The direction of the label tape is not parallel to the direction of product conveying, and it can be achieved by adjusting the inclination of the labeling head.
