What are the factors and solutions for the crooked labeling machine

The main reasons why the labeling machine sticks crooked are the quality of the backing paper, traction scratches, and sticking of labels
.

The solutions are: 1.
Check whether the backing paper is damaged, ask the label supplier to control the depth of die cutting, not cut the backing paper, and use glassine backing paper
.

2.
Check the label travel process, whether there is scratches, and adjust the mechanism if any
.

3.
When checking the labeling, do not stick to the labelled product, and control the length of the labeling if necessary
.

4.
If the label is off-track, loosen the traction mechanism and pull the label back and forth to make it go straight automatically
.

After the label is aligned, clamp the limit rings on both sides to guide the label
.

5.
The direction of the labeling tape is not parallel to the conveying direction of the product, which can be achieved by adjusting the inclination of the labeling head
.

6.
The traction wheel is slipping, the traction wheel is worn, and the traction wheel locking screw is loose.
Both reasons can be tightened.
The traction wheel locking screw can be tightened
.

7.
Product error.
During the product production process, the edge dimensional stability will cause labeling deviation, and control the product quality
