Description

曲折缝旋梭轴前后套管座孔改为偏心套管座孔装置
技术领域
本发明涉及曲折缝缝纫设备领域:具体涉及曲折缝旋梭轴前后套管座孔改为偏心套管座孔装置,改变勾线结构。
背景技术
现在服装与鞋业、箱包材料多种多样,但是曲折缝拼接头层皮、反绒皮、超纤、反绒超纤、四面弹等材料,容易跳线、断线、断针、故障多,这样造成工作效率低,给操作者带来不便。
发明内容
本发明是曲折缝机壳旋梭轴套管座孔改为偏心套管座孔装置,原理适当修改,目的减少跳线断线。
为了达到上述目的,本发明采用如下技术方案:机壳旋梭轴后套管座孔往右偏1.06mm(按角度计算约90.7度),并顺斜通过前套管座孔再连至旋梭尖为一体,图2图3可参考规格与数据,制造厂家可按图1顺序安装,零件互换不会影响,改变角度目的在于勾线结构更合理。
附图说明
图1为原旋梭轴结构图。
图2为旋梭轴与套管一起偏向要求分析图。
图3②为机壳前套管座,①为套管孔,④为机壳后套管座,③为套管孔,发明改进偏向规格数据。
图4为旋梭轴中心线偏向左右各条沿线,论机针经过F点或E点不同数据分析图。
图5为原针板,⑤机针在针板孔中间,标准规格。
图6与图5对比明显⑥机针偏后的缺点,目前很多制造厂有这样的缺点约3%至10%有这不合理之处。
图7与图5对比明显⑦机针偏前,这样改变,保护旋梭尖效果非常好。
具体实施方式
说明书附图所示:图1为原旋梭轴结构图,图2为要求偏斜规格,图3为发明改进实例规格偏向数据,①后套管孔偏右1.06mm(论角度90.7度),②机壳后套管座,③前套管孔并顺斜至旋梭尖部位,图4为旋梭轴中心线往左右各连线分析机针勾线原理,论说这点也是一项怪道理,但有试验使用确实很合理,即右边机针经过F点从最低点回升2.2mm时,旋梭尖距离机针平面为0.02mm,左边机针经过E点从最低点回升4.2mm时,旋梭尖在机针穿线孔上方0.8至1mm时,距离机针平面为0.12mm,特殊就在前面所述右边距机针平面0.02mm,左边距离机针平面0.12mm(怪也在这里),技术分析,论拼接高难度特殊材料、头层皮、反绒皮、超纤、反绒超纤、四面弹等,有对很多大厂机修工调查研究,大家观点经过F点要求靠近机针平面,经过E点大家就没想到为什么旋梭尖容易磨损易断针了,因为经过E点针杆回升大,旋梭尖经过穿线孔上方有凸出明显,既然回升大,线圈也大,发明改变机壳前后旋梭轴套管座孔角度为90.7度理由,达到减少故障,提高工作效率,为了进一步更合理改进,分析图5为标准针板,针板孔⑤机针在正中,图6为中国很多制造厂精确度没有完全达到,有3%至10%如⑥机针微偏针板孔后的错误,梭尖容易磨损,容易断针,图7经过长期试验,⑦机针微偏前有保护旋梭尖作用,在结合机壳前后旋梭轴套管座孔改变角度,效果非常好。
现有技术相比
现有曲折缝多种多样,论服装、鞋业、箱包最常用曲折缝勾线原理大概相同,旋梭轴与下轴转动关系都是90°角,分析右边第一次针杆从最低点回升2.2mm时,旋梭尖刚好到机针平面又是中心线,这时梭尖距机针平面按要求0.02mm,论左边第二次从最低点回升4.2mm时,旋梭尖距离机针平面同样也是0.02mm,根据实践经验总结,并有对很多大厂机修工调查,因为左边第二次勾线,针杆回升幅度偏大,旋梭尖靠近机针穿线孔有明显磨擦现象,产生旋梭尖容易磨损或断针、跳线、断线、故障多、经常维修,技术相比,可参考说明书附图图4右边机针平面与梭尖间隙为0.02mm,左边机针平面与梭尖间隙为0.12mm,这就是发明改变旋梭轴角度作用,论拼接特殊材料头层皮、反绒皮、超纤、反绒超纤、四面弹等材料,右边梭尖要求比较靠近机针平面,而左边梭尖距机针平面是0.12mm,有经过推算,试验的结果,这样梭尖比较不会磨擦机针穿线孔,在勾线过程分析,因为左边机针从最低点回升幅度大,线圈也大,所以说不会影响勾线效果,达到保护旋梭尖作用,运转空间更合理,给维修者更容易修配。
