The hot-melt glue labeling machine is suitable for labeling large cylindrical or square-shaped containers-such as beverage bottles-across various industries including beverages, mineral water, cleaning products, and food. It applies wraparound labels-including OPP film, pearlescent film, paper-plastic composite film, and paper labels-to plastic bottles, glass bottles, and metal cans. Since it utilizes non-shrinkable labeling materials, the printed patterns on the labels remain undistorted, thereby ensuring the aesthetic appeal of the product packaging while simultaneously significantly reducing packaging material costs.
A summary of the hot-melt glue labeling machine's key performance features is as follows:
The production speed of the hot-melt glue labeling machine is customizable. With its infeed and outfeed mechanisms aligned on a single straight axis, the machine can be seamlessly integrated into existing filling lines to boost overall production efficiency.
The equipment is equipped with intelligent "missing label" alarm functions and intelligent label deviation correction capabilities, ensuring that labeling errors are maintained within a tolerance of ±1mm.
Foren's hot-melt glue labeling machines utilize proprietary, self-developed intelligent software. During operation, if a gap occurs in the bottle supply (i.e., a missing bottle), the machine does not require a manual shutdown; instead, it automatically resumes operation the moment the next bottle arrives. This prevents potential equipment damage caused by frequent stop-and-start cycles and helps to reduce energy consumption.
The hot-melt glue labeling machine features imported servo motors and a Siemens PLC control system, making the overall operation of the equipment simple and user-friendly. Its gear system employs a full-servo electronic architecture, while the infeed screw and star wheel work in tandem to ensure smooth and stable product handling-both infeed and outfeed-even during high-speed operation. Should a bottle jam occur, the equipment will automatically shut down and trigger an alarm. Additionally, the bottle-pressing head assembly features an electric lifting mechanism; adjustments for products of varying heights can be easily performed via the Human-Machine Interface (HMI), offering convenient and efficient height configuration.
The hot-melt glue application section of the machine comprises a glue pump, a glue application station, and a glue circulation system. The label conveying section-known as the labeling station-incorporates constant tension control, a label deviation correction mechanism, a traction mechanism, a vacuum transfer drum (for label cutting), a labeling drum, and the glue application mechanism.
The entire hot-melt glue labeling machine is enclosed within safety guards; if a safety door is opened, the equipment will automatically shut down to prevent personal injury resulting from improper operation.
