Front back two sides labeling machine Solution

SKILT double-sided self-adhesive labeling machine (Front and Back Sides Labeling Machine) is a highly efficient packaging device specifically designed for simultaneously or selectively affixing self-adhesive labels to the front and back sides of flat objects, square containers, oval bottles, or slightly irregularly shaped products. It is one of the most core and versatile automatic labeling machines in industries such as daily chemicals (e.g., shampoo, shower gel), food (e.g., flat bottles of condiments, cooking oil drums), pharmaceuticals (e.g., square bottles of oral liquids), and chemicals (e.g., oil drums).

SKILT DLM Series Core Mechanisms and Technological Advantages (How to Ensure Straight Labeling?): Because oval or rectangular bottles are prone to slight angular shifts or wobbling as they move on the conveyor belt, the SKILT double-sided labeling machine is equipped with the following four key dedicated mechanisms to ensure ultra-high precision (typically within ±1mm) of absolute parallelism between the front and back labels:

①　Chain Aligning Device: Before the product enters the labeling area, a pair of synchronously aligned double-pitch chains on both sides clamp and force-align the bottle, correcting its angle and ensuring each bottle moves forward with a perfectly consistent horizontal posture.

②　Top Holding Belt / Top Pressing Belt: After the bottle is aligned, a top holding belt that operates synchronously with the conveyor belt firmly presses the bottle down from directly above, preventing displacement or tipping due to lateral forces as the bottle passes the labeling head.

③　Dual Independent Labeling Heads: The left and right labeling heads are completely independently controlled, driven by a high-performance PLC and servo/stepper motors. Users can individually adjust the label dispensing speed, delay time, and height on the left or right side via the touchscreen.

④　Elastic Wiping/Rolling System: After label dispensing, rigid or highly elastic sponge wheels and brushes on both sides dynamically rub and smooth the label. For elliptical bottles with a certain curvature, a customized pneumatic curved surface labeling mechanism can be used to ensure a perfect fit between the label and the bottle, without air bubbles or curling edges.
