Process Flow
Key Equipment
-
Electronic Weighing Bale OpenerRealizes automatic opening, preliminary opening, precise electronic weighing of bundled fiber raw materials, blending by formula ratio and uniform feeding to next blending /opening procedure.
-
Fine Opener + Cabin BlenderStores multi-formula fibers in large capacity, realizes full vertical & horizontal blending, homogenizing & storage and fine opening, dispersing clumped fibers into single fiber state. Guarantees uniform fiber ratio, consistent loftiness, free of neps and lumps fed into 3D air filling forming chamber, stabilizing finished product 3D structure, basis weight, loftiness and resilience consistency.
-
Preforming ChamberHigh-pressure positive air supply + top negative pressure suction enables disordered 3D stacking preforming of scattered single fibers inside sealed cavity, first forming uniform, fluffy and controllable thickness primary 3D web blanks, then conveyed to subsequent molding, setting and cooling procedures via robotic arms, guaranteeing finished products with uniform density, stable basis weight, isotropy, no warp/weft orientation and consistent 3D structure.
-
Heat Setting Molding PressThe molding procedure realizes specified outline, dimension and hole position standards via coordinated operation of three devices: hot pressing setting – cooling shaping – punching and cutting, guaranteeing smooth production flow and qualified product quality.
-
Rotary Drum Forming MachineAdopts rotary drum as core forming component with vacuum adsorption or mechanical extrusion to realize uniform fiber attachment and molding, stable and efficient forming without obvious fiber orientation deviation.
