The invention discloses a sofa fabric
vacuum coating device, and belongs to the technical field of
upholstered furniture manufacturing, the device comprises a base, a central rotary
workbench, a supporting disc and a central
control system, the central rotary
workbench is connected with the supporting disc above through a supporting rod, and can perform indexing rotation; a
sponge profiling preheating
station, a quantitative glue spraying
station, a fabric negative-pressure pre-stretching
station and a
vacuum coating main station are sequentially arranged around the
workbench, and a static-dynamic separation
layout is formed. Through multi-station linkage, accurate hot-pressing shaping of
sponge, variable-flow glue spraying under
visual guidance and negative-pressure two-way pre-stretching of fabric are sequentially and automatically completed; the device is high in integration level, realizes full-automatic and
continuous production from raw materials to finished products, effectively solves the problems of insufficient pretreatment, non-uniform gluing, fabric wrinkling, low efficiency and
poor quality consistency in the traditional process, and remarkably improves the
coating quality, the production efficiency and the
automation level.
