Take Fineco’s FK803 automatic round bottle labeling machine as example, how to solve this problem.
1. Transparent Label
It is hard to avoid small bubbles if with transparent label, what Fineco focus on is eliminating big bubbles. Fineco must keep clean of the bottle surface, even small dust could bring about big bubbles. Meantime ensure the label is suitable for the bottle, and strictly control the bottle quality.
2. Conventional Bottle Type
Conventional bottle type means cylindrical bottles. Bubbles usually caused by the not matching speed of label-strengthening and transmission. Fineco need to set parameters ‘Automatic traction speed’ and ‘Label-strengthening’ in the touch screen.
3. Tapered Bottle
Wrinkles tend to occur easily for tapered bottles, there could be several situations:
a. Label not match with bottle.
For tapered bottles, Fineco always strongly recommend customers to send us samples to confirm if the label is suitable for the machine. Fineco will simulate the labeling process and suggest customers to make some adjustment if the label can not pasted well.
b. Labeling-strengthening roller need adjustment.
For tapered bottles, Fineco need to adjust the angle of the strengthening roller to adapt to the bottle shape. Sometimes Fineco need to add a top belt to ensure steadily transmission.
c. Label-peeling Plate Adjustment
After confirming the label is suitable, Fineco need to adjust the labeling head to make the label-peeling plate be paralleled to the bottle shape by the adjusters. Meantime, traction speed must be matching with the strengthening speed.
