Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric production, in particular to a non-woven fabric flattening device. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is a fabric that does not require spinning and weaving processes. It is usually made of short fibers or filaments that are randomly or directional arranged to form a mesh structure, and then undergo reinforcement and other processes to make cloth. The production process and production cycle of non-woven fabrics are relatively short, so their cost is relatively low. Non-woven fabrics are widely used, including surgical gowns, protective clothing, masks and diapers in the medical field, home decorations such as bedspreads, sheets and tablecloths, clothing accessories such as adhesive interlinings, linings and shaping cotton, as well as cement packaging bags and other industrial materials in the industrial field.

[0003] In the prior art, during the production and processing of non-woven fabrics, the non-woven fabrics are first humidified and heated to make the non-woven fabrics have a certain plasticity, and then a flattening device is used to evenly flatten the non-woven fabrics. During long-term use and observation, it is found that the current non-woven fabric flattening device is not convenient for adjusting the spacing between the flattening rollers and cannot adapt to the production needs of non-woven fabrics of different thicknesses.

[0004] To this end, the utility model provides a non-woven fabric flattening device. Utility Model Content
