Round Bottle Labeling Machine LM-YDT

Keypack Intelligent Round Bottle Labeling Machine (LM-YDT) is engineered for precise, high-speed self-adhesive label application on round plastic bottles. It delivers a labeling speed of 50–120 bottles/min with photoelectric sensor triggering and Delta PLC control, supporting bottle diameters of 20–100 mm and heights of 40–180 mm. Ideal for food, beverage, pharmaceutical, nutraceutical, and cosmetic packaging lines seeking reliable inline automation.

Product Overview

The Keypack Intelligent (kunbupack) LM-YDT Automatic Round Bottle Labeling Machine is a fully automated inline labeler designed for round plastic containers. Bottles are fed through a conveyor track and separated at equal intervals by an adjustable bottle-spacing mechanism. As each bottle passes, a SICK photoelectric sensor detects its presence and triggers the label dispensing system. A tension control mechanism maintains consistent label web tension throughout the run, ensuring stable label feeding and accurate length positioning. Labels are automatically peeled and applied flat to the target position on the bottle surface by the labeling and pressure-roller assembly. The touch screen HMI (Delta, Taiwan) supports bilingual operation and stores up to 10 product parameter recipes, making changeovers fast and straightforward. The machine integrates smoothly with upstream filling and downstream capping equipment for fully coordinated production line operation.

Key Features and Machine Characteristics

• Wide Bottle Compatibility: Adjustable bottle-spacing mechanism accommodates a broad range of round container sizes (diameter 20–100 mm, height 40–180 mm), reducing the need for dedicated machines per SKU.
• Label Tension Control System: The tensioning design maintains consistent web tension throughout operation, supporting accurate label length control and uniform label peel-off — reducing label waste and misapplication.
• Pre-label Feeding System: A pre-feed mechanism ensures stable label output, smooth application, and high positional accuracy, even at elevated speeds.
• Adaptive Pressure Roller: The pressure roller assembly adjusts to different bottle profiles, maintaining consistent label adhesion quality across varying container geometries.
• Bilingual Touch Screen HMI with Recipe Storage: The Delta touch screen supports Chinese and English interfaces and stores up to 10 product parameter sets, enabling fast, operator-friendly changeovers without specialized training.
• Fully Automatic Operation with Smart Line Integration: The machine runs unattended and communicates intelligently with upstream and downstream equipment, supporting coordinated production line control and reducing manual labor requirements.

Application Areas

• Food & Beverage: Self-adhesive label application on round plastic bottles for sauces, condiments, juices, dairy products, and bottled water in high-throughput food production lines.
• Pharmaceutical: Inline labeling of round medicine bottles, supplement containers, and liquid pharmaceutical packaging where label placement accuracy and consistency are critical.
• Nutraceutical & Health Products: Labeling of protein powder bottles, vitamin containers, and wellness product packaging for retail and e-commerce distribution.
• Cosmetics & Personal Care: Application of product and brand labels on round lotion bottles, serum containers, and shampoo bottles in cosmetic filling lines.
• Chemical & Industrial: Labeling of round plastic containers for cleaning agents, lubricants, and industrial liquid products requiring durable, accurately placed labels.
