How do packaging machines perform color-mark positioning?

To ensure the integrity of the trademark design on the finished packaging bags, color marks used for positioning

To ensure the integrity of the trademark design on the finished packaging bags, color markers used for positioning are typically printed during the production of the packaging material. When using this type of packaging material with printed color markers, photoelectric sensors (also known as "electronic eyes") can track and locate the markers. The control system then activates a stepper motor to rotate, automatically stopping precisely at the intervals between the color markers, thereby ensuring that the trademark design on the finished product remains complete and accurately aligned.

 

The company’s main product lines in packaging machinery include: volumetric packing scales, vacuum packers, baling machines, strapping machines, carton sealing machines, bagging machines, carton forming machines, case packers, wrapping machines, labeling machines, palletizing systems, and custom-designed conveyor lines. Additionally, we manufacture and sell a variety of packaging materials, such as strapping bands and stretch films.
