Forced feeding device of non-woven fabric extruder

Technical Field

The utility model belongs to the technical field of non-woven fabric production equipment, and particularly relates to a forced feeding device of a non-woven fabric extruder.

Background

The non-woven fabric (non-woven fabric) is an ordered or disordered non-woven sheet of fibers obtained by arranging or spraying fibers formed by spinning on a substrate and solidifying and forming in different forms. The non-woven fabric has the advantages of low cost and wide application. The spunbond (spinning) is the most widely used one-step spinning process for forming non-woven fabrics, which is formed by continuous filament fibers, and has high production line speed, high product strength, good dimensional stability, low bulkiness, and slightly poor web forming uniformity and surface coverage. The spinning-bonding method combines a fiber spinning technology and a non-woven forming technology, utilizes a melt spinning principle, and extrudes raw materials from a spinneret plate of a spinning machine head after the raw materials are melted and mixed by an extruder to form melt trickle. The extruded melt stream is cooled by high-speed quenching air, and the fiber is stretched by stretching airflow in the cooling process to form continuous filament with high strength and stable performance. After the filaments are subjected to a filament dividing procedure to form a monofilament structure which is uniformly distributed, the monofilament structure is laid on a net curtain with negative pressure to form a non-woven fiber net. And the fiber web is subjected to hot rolling reinforcement, needling reinforcement or spunlace reinforcement and shaping by a subsequent reinforcement device, and then is wound by a winding device to obtain the product.
