Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a non-woven fabric production cooling system. Background Art

[0002] Nonwoven fabric raw materials are melted, extruded, and sprayed to form fine filaments. These filaments are then drawn and laid onto a web. The resulting web is then shaped and punctured by hot-rolling rollers before being cooled by a cooling system and shipped to the finishing equipment. The existing cooling system utilizes water-circulating chilled rollers. During cooling, the nonwoven fabric rapidly passes over the surface of these rollers, where the low surface temperature cools it to an appropriate temperature. However, in practice, due to the high speed of the nonwoven fabric, the contact surface of the chilled roller with the nonwoven fabric does not have time to cool down from the previous cooling cycle before it is transferred to the next cooling cycle. Furthermore, the chilled roller only cools the inner roller wall, resulting in poor cooling of the outer roller surface in contact with the nonwoven fabric, significantly reducing the overall cooling effect. To address this, we have further improved the existing nonwoven fabric production cooling system. Utility Model Content

[0003] The purpose of the utility model is to provide a non-woven fabric production cooling system, which solves the problem of poor cooling effect in the existing water circulation cooling roller cooling system during the cooling process of the non-woven fabric production process.
