The HSD-4G station glue bottom sealing machine is designed for sealing the bottom of round paper tubes or cans, ideal for cosmetics, food, and gift packaging industries. Equipped with a surround-type gluing system, it applies glue evenly along the tube edge, ensuring strong adhesion between the bottom and the tube body to prevent detachment or air leakage. The machine supports quick adjustments for various tube sizes for easy changeover. Integrated with assembly lines, it automates feeding, positioning, gluing, pressing, and curing, greatly enhancing sealing strength and integrity. Compared with traditional cardboard or snap-on methods, glue sealing provides stronger and smoother results, reducing defect rates and improving packaging quality and efficiency.

1. Cylinder-Specific Design: Equipped with curved positioning stations and a rotary gluing mechanism, it ensures even glue coverage on the curved bottom surface, preventing missed or excessive application.

2. High-Precision Gluing System: Features quantitative control and adaptive nozzles that automatically adjust glue volume and angle based on cylinder diameter, ensuring consistent glue lines.

3. Quick Changeover: The station module can be rapidly adjusted to accommodate various cylinder sizes (e.g., diameter 80–300mm), minimizing downtime for multi-variety, small-batch production.

4. Strong Sealing Performance: The cured glue forms a flexible, durable seal that resists vibration and impact, ideal for food cans, chemical drums, and paper tubes.

5. Automation Ready: Supports integration with conveyors, rotary tables, or robotic arms for automatic loading, gluing, pressing, and inspection, significantly reducing manual labor.
