Description

Technical Field

[0001] The utility model relates to the technical field of nonwoven fabric production, in particular to an air pressure cotton feeding machine with uniform cotton output. Background Art

[0002] Nonwoven fabric is a kind of fabric that does not require spinning and weaving. It is formed by directional or random arrangement of textile staple fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is a new type of fiber product with soft, breathable and flat structure formed directly from polymer slices, staple fibers or filaments through various fiber web forming methods and consolidation technologies. Nonwoven fabrics have a wide range of applications. In terms of medical and sanitary fabrics, they are often used to make surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.

[0003] When making sanitary cloth, the fiber cotton material needs to be loosened first. After the loosening, the scattered cotton material is initially spread into a cotton net in a cotton feeding machine, and then the cotton net is made dense by a carding machine. However, due to the uneven distribution of cotton material during feeding, the thickness of the cotton net spread out by the traditional cotton feeding machine varies greatly in the width direction, which makes it difficult to have a consistent thickness of the fabric after subsequent processing. Therefore, it is necessary to produce a pneumatic cotton feeding machine with uniform cotton output to solve the above problems. Utility Model Content
