摘　　要：起毛针布的包卷张力对面料的风格有重要影响,张力过大则出毛量少,张力过小则针布会松动,张力松紧不一会造成更多麻烦,如横条、稀漏、勾丝、破洞甚至频繁断布。长期以来,包针张力的控制都是靠老师傅的经验和手感。随着市场竞争的加剧,人们对起毛面料的质量要求越来越高,开始关注针布张力,提出了量化包针张力的需求。文章通过仔细研究传统包针器的包针过程发现,影响包针布张力的因素主要有两点:一是更换针布时压紧螺栓不方便复位,二是针布自身高度偏差的影响无法消除。针对上述两点提出改进方案,一是借鉴快速夹钳机构设计快速精准复位机构,二是包针器底部开释放槽,压板改为弹簧钢板,建立弹性补偿机制。通过与弹簧秤的配合使用,针布张力得以量化,可以指定张力数值,张力变动量控制在±5.00%以内。The wrapping tension of pilling needle cloth has a significant influence on the style of the fabric.If the tension is too large,the amount of yarn produced will be reduced.If the tension is too small,the needle cloth will loosen,and different tension can cause more trouble,such as horizontal stripes,loose threads,snagging,holes,and even frequent cloth breakage.For a long time,the control of wrapping needle tension depends on the experience and feel of experienced craftsmen.With the intersification of market competition people have increasingly high requirements for the quality of woolen fabrics,and they have begun to pay attention to the tension of needle cloth,proposing the need to quantify the tension of needle wrapping.The article carefully studies the needle wrapping process of traditional needle wrapping devices and finds that there are two main factors that affect the tension of the needle wrapping cloth.Firstly,it is inconvenient to reset the clamping bolt when replacing the needle wrapping cloth,and secondly,the influence of the height deviation of the needle wrapping cloth itself cannot be eliminated.An improvement plan is proposed for the above two points.Firstly,a quick and accurate reset mechanism is designed based on the quick clamp mechanism.Secondly,the bottom of the needle wrapping device is opened and released,and the pressure plate is changed to a spring steel plate to establish an elastic compensation mechanism.By using it in conjunction with a spring scale,the tension of the needle cloth can be quantified,and tension values can be specified,with tension variation controlled within±5.00%.
