This hot melt glue spraying laminating machine adopts innovative fibrous hot melt spraying and precise activated carbon scattering technology to replace traditional stirring and drying processes, delivering higher efficiency, better bonding and stronger environmental performance.

Working Principle
The machine sprays hot melt adhesive in uniform fibrous form onto the base material; activated carbon particles/powder are evenly scattered onto the adhesive surface for instant anchoring. A second layer of hot melt adhesive is applied before laminating with the top substrate, forming a stable, high-performance activated carbon filter composite. Multiple glue spraying head and powder scatter devices can be added to achieve a larger amount of activated carbon powder scatter with good bonding fixation. The whole line operates without a high-power drying oven, greatly saving energy and space.
Key Advantages
Energy-Saving & Eco-Friendly: Eliminates high-power drying ovens; uses solvent-free environmental hot melt adhesive, replacing traditional glue-powder mixing and oven drying.
Precise Dosage Control: Hot melt adhesive and carbon powder feeding are fully adjustable to meet customer-specific weight and performance requirements.
High Automation & Labor Saving: Integrated unwinding, positioning, spraying, scattering, laminating and rewinding; auto tension, auto cutting and auto shaft changing reduce manual intervention.
Stable & Uniform Bonding: Fibrous hot melt coating ensures firm, even adhesion of activated carbon, improving filtration efficiency and service life.
Wide Material Compatibility: Suitable for nonwoven fabrics, foams, filter papers and other substrate lamination for automotive and industrial filters.
