Description

Technical Field

[0001] The utility model relates to the technical field of nonwoven fabric production, in particular to a carding machine with convenient roller adjustment. 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 cotton web, after being loosened and initially formed into a web, needs to be transported to a carding machine to comb the cotton web fibers so that the fiber cotton can be arranged in a certain direction as much as possible, thereby making the cotton web stronger and tighter, so that it can be used to make various products. When combing the fiber cotton, the cotton web is initially combed by a pre-combing roller, and then the cotton web is transported to the working roller through a stripping roller for further combing. Generally speaking, a plurality of sets of one-to-one paired stripping rollers and working rollers are arranged on the periphery of the pre-combing roller. However, in order to adjust the thickness of the cotton web, it is often necessary to adjust the relative distance between the stripping roller, the working roller and the pre-combing roller. During adjustment, it is necessary to keep the stripping roller and the working roller in the radial direction of the pre-combing roller, which makes the adjustment very cumbersome, time-consuming and labor-intensive. Therefore, it is necessary to produce a carding machine that is easy to adjust the rollers to solve the above-mentioned problems. Utility Model Content
