LABELLING PETplanet Insider Vol. 24 No. 09/23 www.petpla.net 14 Analysis of modular hot-melt & self-adhesive labelling machine Tech-Long Packaging Machinery Co. Ltd, Guangzhou, known for PET bottle blowing, filling and packaging equipment, also offers modular hot-melt and self-adhesive labelling machines. The hot-melt labeller can apply the label anywhere on the container by rotating the container with a label transfer system controlled by a servo motor. The modular design makes the model adaptable and flexible, suitable for various round/irregular containers and materials, and is widely used in industries such as food and beverages, cosmetics, chemicals, spices, spirits, etc. Precision positioning This device adopts servo system bottle rotation positioning technology, which can achieve labelling at any position of the container with high positioning accuracy and fast response speed. Whether it is a circular, square, or elliptical container, this device is claimed to be able to accurately locate and label, meeting the needs of containers with different shapes. The equipment’s labelling station has a multi-directional quick adjustment function, which can meet the labelling needs of irregular surfaces such as cylinder and cone. Tech-Long says that this device can be flexibly adapted to achieve precise labelling effects. In order to maximise the accuracy of labelling and reduce system vibration and noise, the modular hot-melt & self-adhesive labelling machine adopts a fully servo labelling station design. This design can ensure the accuracy and stability of labelling, improve production efficiency and product quality. Modular multi-labelling station layout The equipment adopts a modular design, and the number of labelling stations can be increased or decreased according to customer needs, meeting the requirements of multiple labelling. Customers can configure the number of labelling stations based on product characteristics and needs, achieve personalised labelling solutions. The modular hot-melt & self-adhesive labelling machine can achieve different types of combined labelling requirements. Whichever way it is used, the device can be flexibly combined to meet the labelling needs of different products. The modular hot-melt & self-adhesive labelling machine is widely used in industries such as food and beverage, cosmetics, chemical, seasoning, and alcohol. It can adapt to full bottle labelling or local labelling, such as neck labelling. This device can use various packaging materials such as OPP, BOPP, pearl film, composite paper, etc. to achieve efficient and accurate labelling operations. Operational principle The device conveys bottles to the bottle tray through the bottle inlet door, screw (or non-screw bottle inlet mode) and bottle inlet star wheel, accurately positions them through the bottle pressing head. Subsequently, the bottle reaches the labelling position with the rotation of the large plate for labelling. After being cut by a cutting knife, the label enters the labelling wheel and is coated with glue by a rubber roller. Then, it is attached to the bottle body as the labelling wheel rotates. Finally, the bottles with labels are transported to the conveyor chain at the exit through the bottle exit star wheel. The production speed of the modular hot-melt & self-adhesive labelling machine can be automatically controlled. The device can automatically adjust the bottle infeed and outfeed flow rate as needed. In addition, the bottle inlet door can ensure the minimum bottle storage capacity at the inlet and automatically stop the bottle inlet operation when the outlet is full. This control function ensures smooth operation and efficient production of the equipment. The Tech-Long modular hot-melt & self-adhesive labelling machine has been designed to demonstrate strong technological innovation capabilities in the labelling industry through its highprecision positioning and flexibility and has broad application prospects. Its fully servo labelling station design is claimed to ensure the accuracy and stability of labelling. Modular design and a combination of multiple labelling types enable the device to adapt to different products and needs. www.tech-long-intl.com
