What should I do if my hot melt adhesive labeling machine applies labels crookedly?

If a hot melt adhesive labeling machine applies labels crookedly, you can fix it by following these steps:

• Adjust the label position: Ensure the label hanger and positioner are correctly positioned to prevent the label box from tilting.
• Inspect the equipment components: Tighten the tape pressure device and traction mechanism to prevent the tape from loosening or slipping.
• Properly position the product: Ensure the object is parallel to the labeling direction and rotates smoothly.

If a hot melt adhesive labeling machine applies labels crookedly, we recommend checking the following three points:

• Adjust the parallelism of the conveyor belt to ensure vertical alignment with the labeling head (deviation should be less than 0.3mm);
• Calibrate the photoelectric sensor to ensure it accurately detects the gap between labels (adjust the sensitivity to medium-high).
• Check the hot melt adhesive temperature (150-180°C) and adhesive uniformity (0.1-0.3g/label).
