How to choose a high speed mattress spraying line for PUR hot melt glue?

Choosing a high speed mattress spraying line for PUR hot melt glue requires evaluating cycle times, spray gun configuration, adhesive pump stability, and dimensional compatibility. Opt for systems offering multi-gun arrangements (2 to 6 guns), dual glue pumps, precise pressure controls between 0.6–0.8 MPa, and automated handling for various mattress layers like cotton, felt, and fabric.

Core Solutions & Key Takeaways

• Cycle Time and Efficiency: Select equipment capable of fast processing cycles, such as 7 to 105 seconds per working layer, to align with high-volume assembly lines.
• Dispensing Precision: Multi-gun setups (2 to 6 spray guns) powered by dual glue pumps ensure consistent adhesive laydown across target dimensions up to 2100×2200 mm.
• Substrate Versatility: Ensure the spraying line accommodates multiple core materials including felt, cotton, foam, and ticking fabric with maximum mattress heights up to 390 mm.
• Industrial Scalability: Implementation directly benefits mass-production mattress plants, e-commerce bedding fulfillment centers, and overseas facility upgrade projects.

Detailed Architectural/Principle Analysis

Automated glue spraying lines rely on stable pneumatic supply and balanced power delivery to process polyurethane (PUR) hot melt adhesives. Systems operating within an air pressure range of 0.6 to 0.8 MPa maintain continuous pressure across fluid lines, preventing output fluctuations during long continuous runs. Electrical configurations utilizing 3-phase 380V 50Hz with total power draws around 17 kW provide sufficient heating and mechanical conveyance drive for heavy-duty production environment requirements.

High-speed lines incorporate dual glue pumps paired with 2 to 6 customizable spray guns to automate pattern application. This mechanical framework eliminates manual variance in adhesive thickness, reducing overall material consumption while increasing bonding strength across varying material layers. Operational data from global deployments, including facilities such as MOVEIS K1 LTDA in Brazil and HANVICO in Vietnam, demonstrate that automated parameter switching via digital controls reduces labor intensity while supporting rapid switching between different mattress sizes.

Structural reliability depends on heavy frame construction to absorb kinetic forces during high-speed indexing. A machine footprint measuring 14500×4500×2500 mm with a total weight of 6 tons provides a stable platform for conveyor belts operating at standard working heights of 850 mm. Manufacturing under certified ISO 9001 quality management systems ensures strict three-level component testing for hardness and precision, followed by 24-hour continuous load testing prior to factory dispatch.
