Pneumatic Pump Hot Melt Glue Machine Delivers Stable Bonding for Liquor Rigid Box Manufacturing

Most liquor packaging factories face common troubles in rigid wine box gluing: uneven glue lines, nozzle clogging triggered by tiny impurities in hot melt adhesive, and unstable adhesion causing box edge opening after long-distance transportation. Keqi pneumatic pump hot melt equipment solves these pain points perfectly for wine gift box mass production.

Different from traditional gear pump hot melt systems, the air-driven feeding structure features stronger impurity tolerance. Even with minor foreign particles inside hot melt glue, the pneumatic pump maintains steady glue supply and greatly reduces nozzle blockage, cutting frequent shutdowns for gun cleaning. Operators adjust heating temperature and glue output volume according to grey board, coated art paper and special textured paper of wine boxes, forming thin, straight glue trails on box folding flaps without overflow or glue shortage.

The matched hot melt gun realizes rapid glue cut-off. No wire drawing or residual dripping contaminates exquisite bronzing and color printing on red wine boxes. The whole system runs smoothly with rigid box automatic folding equipment. After hot melt bonding, wine box corners stay neat and tight, resisting splitting during stacking and delivery. Many alcohol packaging manufacturers replace old gear pump machines with this set. Production uptime rises, adhesive waste decreases, and finished wine boxes maintain uniform high-grade appearance for export orders.
