Working principles of sticker labeling machine
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.
