In the packaging industry, the core of servo glue coating line is high-precision glue coating+automated connection+glue saving and efficiency improvement. It is mainly used in color boxes/gift boxes, cardboard boxes/corrugated boxes, paper plastic composites, labels/films, and sealing/sealing.
1、 Color box/gift box (packaging mainstay)
Application scenarios: Glue coating on the side/flap of folding boxes such as cosmetics boxes, wine boxes, gift boxes, and phone boxes, window bonding, and paper tray/inner lining bonding.
Process value:
Servo control glue: glue line width error ≤ 0.2mm, glue amount fluctuation ≤ ± 1.5%, no glue overflow, no glue interruption.
Irregular/curved surface adaptation: Multi axis linkage+visual positioning, making it easy to apply glue to irregular windows and curved edges.
Save glue and improve efficiency: 15% -20% less glue than manual production, with a production capacity of up to 30 pieces/minute and a defect rate of ≤ 0.3%.
2、 Carton/Corrugated Packaging (Logistics and Industrial Packaging)
Application scenarios: bonding of corrugated cardboard box surface paper and corrugated core, adhesive coating on the side seams of cardboard boxes, sealing of express boxes, and bonding of reinforcing ribs for home appliance boxes.
Process value:
High speed connection: docking with the glue box machine/laminating machine to achieve full automation of feeding → gluing → bonding → pressing → drying → unloading.
Wide adaptability: The glue coating width can reach 1.4m, suitable for different types of ribs (A/B/C/E/F).
Moisture proof enhancement: The adhesive layer is uniform, improving the durability, compression resistance, and moisture resistance of the cardboard box, reducing transportation damage.
3、 Paper plastic composite/vacuum formed packaging (food/medicine/electronics)
Application scenarios: bonding of vacuum formed covers with paper cards, composite of food trays (paper+PP/PE), back coating of pharmaceutical foam covers, paper plastic edge sealing of electronic products.
Process value:
Low temperature adaptation: Suitable for water-based adhesive/low-temperature hot melt adhesive, does not burn paper cards or damage plastic substrates.
Strong sealing: The adhesive film is continuous without breaks, meeting the requirements of food/medicine sterility, sealing, and leakage prevention.
Clean appearance: no glue overflow, no wire drawing, enhancing packaging texture and grade.
4、 Labels/lamination/soft packaging (printing and daily chemical)
Application scenarios: Back coating of self-adhesive labels, composite of BOPP/PET/PE film and base paper, edge sealing/bottom sealing of flexible packaging bags, and adhesive coating of composite films.
Process value:
Ultra thin and uniform: The thickness of the adhesive layer can be controlled between 0.02-0.1mm, thin and uniform, without affecting label die-cutting/waste disposal.
High speed stability: servo synchronous cutting, speed can reach 80-150m/min, suitable for continuous production of coil materials.
Good weather resistance: The adhesive layer has strong adhesion, high and low temperature resistance, moisture resistance, and anti curling edge, suitable for long-term storage of daily chemical/food products.
5、 Sealing/Sealing and Special Packaging
Application scenarios: Glue coating for paper box sealing strips, adhesive backing for express delivery orders, glue coating for bottle cap/box cover sealing gaskets, and adhesive reinforcement for honeycomb paper/paper tubes.
Process value:
Flexible switching between point/line/surface: Servo programming can quickly switch between point, strip, and full surface glue spraying, making it versatile for one machine.
Low maintenance: automatic cleaning+fault alarm, rubber/specification replacement can be completed within 10 minutes, reducing downtime.
