Description

Technical Field

[0001] The present application relates to the technical field of nonwoven fabric production, and in particular to a meltblowing device for nonwoven fabrics. Background Art

[0002] Nonwoven fabrics, also known as nonwoven fabrics, are new fiber products with softness, breathability and flat structure, and have the characteristics of short process flow, high labor productivity, significant economic benefits, many product varieties and wide application range. Melt-blown nonwoven fabrics are a general and cost-effective method for directly producing nonwoven fabrics with microfiber structure using polymers, which have excellent filtering, shielding, thermal insulation and oil absorption properties.

[0003] Reference Figure 1 The current meltblown device includes a discharging mechanism and a receiving mechanism. The receiving mechanism usually adopts a roller to receive the meltblown fibers melted by the discharging mechanism, so that multiple fibers form a non-woven fabric in a mesh form on its surface, and then the non-woven fabric is transported by rotation; however, after the existing roller is in contact with the fibers for a long time, the temperature of the roller itself will gradually increase, resulting in a delay in the time for the subsequent non-woven fabric to cool into a non-woven fabric, which in turn leads to poor quality of the transported finished product.

[0004] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention
