Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric opening mechanism. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric, a new type of fiber product with soft, breathable and flat structure. Its advantages are that it does not produce fiber scraps, is strong, durable and silky soft. It is directly formed by using polymer slices, short fibers or filaments to form fibers through airflow or mechanical webs, and then through water spunlace, needle punching, or hot rolling reinforcement, and finally through post-finishing. Before the production of non-woven fabrics, the production raw materials need to be loosened. Loosening is the process of loosening the compressed and entangled fiber raw materials and removing impurities. It is an important part of the non-woven fabric production process. In order to reduce impurity pollution and produce high-quality non-woven fabrics, it is necessary to first loosen the raw materials, remove various impurities, and mix them evenly. The quality of the opening of the fiber raw materials is directly related to the quality of the non-woven fabric products.

[0003] After searching, the prior art publication number CN203613319U proposed a loosening machine, including a conveying device that transmits from left to right, an inner cover shell, and an outer cover shell. A cotton pressing roller is arranged just above the end of the conveying device, and a flat cylindrical inner cover shell is arranged on the right side of the end of the conveying device. The surface of the inner cover shell is provided with meshes, and a cotton feeding roller is arranged between the inner cover shell and the conveying device. A roller is coaxially arranged inside the inner cover shell, and corner nails are evenly arranged on the surface of the roller. A fixed blade is arranged on the inner surface of the inner cover shell, and the inner cover shell is provided with a cotton outlet. A closed outer cover shell is arranged around the inner cover shell. However, when processing, the material is directly placed on the conveying device for feeding. Since the conveyor belt is on the outside, dust and dust attached to the original material will be attached, so that the raw materials loosened will have impurities, affecting the quality of the raw materials. In addition, due to the light weight of the fiber, a lot of fibers are often entangled on the corner nails, which is easy to accumulate. If the accumulated fibers are not cleaned in time, they are easy to be rolled into the non-woven fabrics processed later, thereby affecting the quality of the non-woven fabrics.
