Automatic Rotary OPP Hot Glue Labeling Machine
Stable Capacity: 12000BPH
The containers are picked up by the infeed star wheel and transferred to the container table. The container rotation begins when they are positioned between container plates and centering bells.
The speed of the feed roller is adjusted to the required label length for continuous web tension. A standard threading unit ensures optimal film feed. In the cutting unit, the labels are precisely cut while a PLC command and servo-motor provide an exact cut-off point.
Two narrow strips of hot melt glue the labels together, which are applied by a heated glue roller to the leading and trailing label edges. The label with the glue strip on its leading edge is transferred to the container. This glue strip ensures an exact label positioning and a positive bond. As the container is rotated during label transfer, labels are applied tightly.
Gluing of the trailing edge ensures proper bonding

The safety part of the machine
In order to keep the operator safe, when the machine is running, please close the protective doors.
Lack of label alarm:
Set an alarm to remind the operator to change the label when the label will be used out.
Lack of bottle alarm:
When lacking a bottle the machine will stop and make an alarm. The machine will restart automatically as soon as the bottles have been put which will facilitate online production.
The leak of labeling alarm:
To control the quality of labeling.
When the pressure cannot meet the equipment requirement, the machine will stop to against bad products produced.
When the vacuum cannot meet the equipment requirement, the machine will stop to against bad products produced.
When the temperature cannot meet the equipment requirement, the machine will stop to against bad products produced.
Infeed bottle → pre-position →label cutting → gluing → labeling→ label by press out → finished.
