Equipment details

Inside the OPP labeler.

Explore the components that guide each label from the roll to the bottle, with servo control throughout feeding, cutting and positioning.

01 / COMPONENT

Hot-glue labeling station

Independent servo motors control label unwinding and feeding. The automatic deviation corrector works with the feed roller to keep cutting accuracy within 1 mm.

A separately driven vacuum drum works with the gluing unit to maintain labeling accuracy.

Electric height adjustment makes the labeling station easier and faster to set up.

02 / COMPONENT

Deviation corrector

Automatic web alignment works with the independent servo label-feed roller to keep labeling accuracy within 0.3 mm.

Label tilt remains below 1° to support stable cutting.

03 / COMPONENT

Vacuum cutter drum

The cutting knife uses a special material from Germany for durability and wear resistance.

Constant-temperature cooling limits heat buildup during high-speed operation and extends service life.

The specified cutting failure rate is below 1 in 10,000.

04 / COMPONENT

Vacuum label suction drum

An independent servo motor coordinates the suction drum with the cutter drum for smooth label transfer. The internal vacuum circuit keeps labels securely held.

Label detection triggers an alarm and stops the machine if a label falls off.

A one-piece aluminum-alloy suction block improves seam alignment and supports even glue application. Its non-stick surface reduces residual glue.

05 / COMPONENT

Glue roller

A honeycomb-pattern roller provides adjustable glue thickness, with approximately 80,000 labels per kilogram of glue.

A recirculating glue system reduces residue and splashing while recovering glue for reuse.

A non-contact heat source inside the roller helps prevent label scorching. Heat-resistant bearings and heat-dissipating materials support stable operation.

Label roll trays with pneumatic clamping

06 / COMPONENT

Label tray

An independent servo motor and buffer clutch work together to unwind the label roll steadily.

Pneumatic clamping and release simplify roll changes through an easy-to-operate air valve.

A SUS 304 stainless-steel support structure provides stability and durability.

Bottle infeed starwheels and central guide plate

07 / COMPONENT

Infeed mechanism

A feed screw and starwheels made from ultra-high-polymer materials are customized to the bottle size.

Bead inserts in the starwheels and central guide plate reduce friction and help prevent bottle scratches.

08 / COMPONENT

Bottle pressing mechanism

A three-stage tension-spring structure guides vertical movement while applying uniform pressure to the bottles.

Electric lifting adjustment reduces manual setup work and saves time.

Servo-controlled bottle positioning system

09 / COMPONENT

Servo positioning system

Full servo control provides accurate, stable and efficient station positioning.

The positioning system accommodates shaped bottles for orientation and labeling.
