Rotary OPP Bottle Labeller Hot Glue Melt Labeling Machine Equipment
Label Applicator For Plastic Bottle Water Factory
Working principle
At the beginning of the working process, the bottles are fed to the
labeling machine at a constant speed on the conveyor belt. The
mechanical fixing device separates the bottles by a fixed distance,
and pushes the bottles along the conveyor belt. The mechanical
system of the labeling machine includes a driving wheel, a labeling
wheel, and a reel.
The driving wheel drags the label tape intermittently, the label
tape is pulled out from the reel, and the labeling wheel will press
the label tape on the bottle after passing through the labeling
wheel. An open-loop displacement control is used on the reel to
maintain the tension of the label tape. Because the labels are
closely connected to each other on the label tape, the label tape
must constantly start and stop.
The label is attached to the bottle when the labeling wheel moves
at the same speed as the bottle. When the conveyor belt reaches a
certain position, the label belt drive wheel will accelerate to a
speed matching the conveyor belt, and after the label is applied,
it will decelerate to a stop.
Process:
Bottle infeed → pre-position →label feed →labeling→finish

Safety part of the machine:
Safety protection: In order to keep the operator safety ,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 use out
Lack of bottle alarm: When lack of the bottle the machine will stop
and make an alarm .The machine will restart automatically as soon
as the bottles have been put that will facilitate on-line
production
Leak of labeling alarm: To control the quality of labeling
Pressure testing : When the pressure can not meet the equipment
requirement ,the machine will stop to against bad products produce
