Automatic Opp labeling machine

The containers are picked up by the in feed 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.
Process: In feed bottle → pre-position →label cutting → gluing → labeling → label by press out → finish

Labeling type: all around

Glue type: hot melt

Container diameter: 35mm-100mm

1.1).easy operation to adjust label cutting knife

1.2).vacuum drum made of high rigid material to reduce friction and static

1.3) rapid changeovers: modular design and quick release change parts have changeovers fast and easy in ten

minutes

1.4).using handle to adjust the position of cutting knife is possible and exactly

1.5).vacuum manifold at the lower part of drum and cutter, made of heat & wear resistant material

1.6).automatic label length controller to adjust position of I-MARK

2. Label

①label material: OPP, PVC, PAPER etc

②label size：as demanded

③labeling method: line type

3. Machine description

3.1) roll-fed type

3.2) label in-fed from label station is conveyed to label in-feed roll-er through label guide roller

3.3) sensors will check I-MARK of label automatically when label reaches label in-feed Roller

3.4) as soon as the position of I-MARK is confirmed, Encoder will adjust the operation speed of label in-feed roller and then appoint the label cutting position

3.5) label which has been cut is conveyed to vacuum drum

3.6) after checking label attached on vacuum drum by sensor, label is conveyed to glue roller and then inject hot melt on label

3.7) to adjust containers by in-feed star wheel and do labeling in roller zone for the first time and then labeling operation will be done perfectly by side belt.

4. Safety

4.1) control: PMC, inverter

4.2) safety attachments

① Overload running safety equipment attached on driving zone

② Stopper for abnormity operation of in-feed star wheel

③ No bottle fed (sensor check)

④overload for bottle fed (sensor check)

⑤no bottle no labeling
