Description

Technical Field

[0001] The invention relates to the technical field of nonwoven fabric equipment, in particular to an energy-saving mechanism for manufacturing nonwoven fabric. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics and melt-blown fabrics, are made by blowing out molten polypropylene with high-pressure hot air, and then cooling it during the blowing process to form fabric through filaments, which is also the origin of the name melt-blown fabric. The melt-blown non-woven process uses high-speed hot air to draw the polymer melt stream extruded from the spinneret of the melt-blowing die head, thereby forming ultra-fine fiber filaments, which condense on the condensing mesh curtain or metal forming cylinder and rely on their own bonding to form non-woven fabrics.

[0003] The manufacturing process of non-woven fabrics mainly includes: preparing polymers in a barrel, melting and extruding in an extrusion screw, metering by a metering pump, forming hot air through air heating equipment, air compressors, Roots blowers, centrifugal compressors and other blowing equipment, stretching the polymer melt in a meltblown die head, and blowing it into filaments by hot air. The hot air drives the filaments to contact the surface of the metal forming cylinder, thereby forming a non-woven fabric that is collected by a roller.

[0004] Traditional equipment sends a large amount of air into the heating chamber and produces a hot air flow through electric heating wire heating or combustion heating. The energy consumption required is serious, and the serious energy consumption leads to increased production costs. The traditional method is to recycle the hot air flow and reuse it, but the current equipment has a simple recovery mechanism and poor heating effect. For this reason, a new energy-saving mechanism is established. Summary of the invention
