◆ 1. Layout for Hot Melt Labeling Machine
◆ 2. Method of Operation
The containers are picked up by the infeed starwheel 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.
Process: Infeed bottle → pre-position →label cutting → gluing → labeling → label by press out → finish

◆ 4. 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 |
|
Vacuum testing |
When the vacuum can not meet the equipment requirement ,the machine will stop to against bad products produce |
|
Temperature testing |
When the temperature can not meet the equipment requirement , the machine will stop to against bad products produce |
