The utility model provides a wetless traction pre unfolding device, which comprises a frame, a traction component and a tension component installed on the frame. The traction component comprises five traction rollers arranged in turn from left to right, and the adjacent two traction rollers are staggered up and down. The tension component comprises three tension rollers, and the adjacent two tension rollers are staggered up and down, and the tension rollers are cylindrical And the surface is toothed. The utility model has the advantages of reasonable structure, simplicity and economy. Five identical traction rollers are arranged up and down in front and back for traction of the tow, which can not only ensure enough traction, but also prevent the loose tow from slipping and being pulled; three tension rollers are V-shaped, and the resistance of the tension roller is controlled by the magnetic powder brake to provide the tow with uniform tension for the subsequent process; the surface of the tension roller is toothed, so that It not only provides resistance, but also plays a very good role in wire spreading; the effective overall layout reduces the cost of equipment, reduces the installation error, and makes the production line shorter.

技术介绍
高性能纤维"UD"无纬布,是采用高性能纤维为基材,如超高分子量聚乙烯纤维、芳纶,经先进高科技设备均匀铺丝,用高强弹性体树脂浸渍涂胶和薄膜粘合,再经正交复合层压而成。其具有手感柔软、密度小、耐磨蚀、抗冲击、抗切割韧性强等优异性能,产品广泛应用于软质防弹衣、轻质防弹头盔、轻质防弹装甲板材,防刺、防切割服装衬片和特殊公共防暴设施,是当今世界强度最高、比重最轻的防弹材料。无韦布生产主要有单丝卷绕成片、多丝平展成片两种方式,然而单丝卷绕效率低下,多丝平展成片已成为主流。在多丝平展成片的生产技术中,把每根纤维展开成均匀扁薄的丝束是保证产品质量的核心技术,为确保均匀展丝,必须保证每根纤维丝束张力大小相近。如果每根纤维的松紧不同,则其展丝宽度不均,形状不规整,成品无韦布会出现纤维空隙和纤维叠丝,成品质量下降,对使用无韦布的下游产品质量都有很大的影响。在当下无韦布生产过程中,普遍存在因展丝效果不好,出现空隙、叠丝,成品质量难以 ...
