class="newsCon" id='d'>  <div> <span style="font-size:14px;"><a href="http://www.024yinshua.com/"><strong>工业缝纫?/strong></a>如何进行机缝练习?下面就让通用缝纫机厂家的小编给大家介绍下?br /> <br /> 一、空机练?/span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">电动缝纫工学习的最初阶段是空机练习。空机练习阶段要先在专业技术人员或专业教师的指导下检查、了解所使用机器的型号及机器特点、安全操作规程,然后才可以进行实际空机练习?/span></div> <div> <span style="font-size:14px;">1、坐位高低要适中,一般以缝纫者坐在位子上双手可自然地放在缝纫机台板上为适。缝纫者坐于座位,双脚应平放在缝纫机脚踏板上。为了便于操纵缝纫机或脚踏板,并且不至于很快就疲劳,臀部与座位面适当接触,既不要坐得过满,也不要坐得太少。此外。歪斜着身体,依靠单股支撑人体重心,或坐时喜欢将座位翘起以及背靠椅背的坐姿,都是不正确的。正确的坐姿应该是臀部坐在凳?/3的位置,不偏不倚,舒适自然。这样既不妨碍下面双脚操纵时的用力,也不影响上体及双手从事缝纫时的动作?/span></div> <div> <span style="font-size:14px;">2、开始操作前卸下机针?/span></div> <div> <span style="font-size:14px;">3、接通电源插座?/span></div> <div> <span style="font-size:14px;">4、下平缝机台板下的开关?/span></div> <div> <span style="font-size:14px;">5、搬动机头前侧的压脚扳手,将压脚抬至最高点,以防磨损送布牙?/span></div> <div> <span style="font-size:14px;">6、双脚自然踏在平缝机传动机构运转?/span></div> <div> <span style="font-size:14px;">7、通过反复多次的空机练习,操作者便能较熟练掌握平缝机的运转速度,从慢速启动到中速、高速运转及匀速平稳运行,再从高速到中速转入慢速到停机?/span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">二、实缝缝线练?/span><br />  </div> <div style="text-align: center;"> <span style="font-size:14px;"><img alt="" src="/uploads/allimg/181220/1-1Q22010595U07.jpg" /></span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">通过空机反复的练习,操作者要做到脚、手、眼三者的协调配合和控制。然后便可进入实缝练习?/span></div> <div> <span style="font-size:14px;">(一)纸上空缉训?/span></div> <div> <span style="font-size:14px;">这是在掌握了缝纫机操纵方法的基础上,在纸上进行不穿缝线的实缝模拟训练,重点在于使初学者通过缉纸训练,逐步做到手、脚、眼协调配合,既可训练动作又可节约布料?/span></div> <div> <span style="font-size:14px;">1、机缝时手的辅助动作 机缝时,缝纫方向的控制及缝件的平服等都是用手来帮助控制的。机缝中手的辅助方法多变,在通常情况下,一般左手放在缝件外的左前方,捏住或夹住缝件向外微拉;右手放在缝件里的右后方,拇指在下,其余四指在上,捏住缝件向前微送。如此用手一前一后把住缝件,可以边输送缝件边转变缝纫的方向。当缝纫两层或两层以上的布料时,由于上下层布料受到的阻力不一样,上层与下层布料向前输送的速度也不一样,因此,容易产生缝缉不齐等质量问题?/span></div> <div> <span style="font-size:14px;">2、缉直线 在纸上分别画数条直线,有短有长,然后按线印进行空缉练习,目的在于训练操作者缉直线?/span></div> <div> <span style="font-size:14px;">3、缉弧线 在纸上分别画出数条弧线,弧度大小及弯曲方向有所变化,然后按线印练习?/span></div> <div> <span style="font-size:14px;">4、缉几何?在纸上分别画大小不一样的长方形、正方形、五角形等,然后练习,目的在于训练缉有角几何图形时转角自然。尖角分明?/span></div> <div> <span style="font-size:14px;">5、缉平行?在纸上分别画直形、弧形的平行线,间隔距离0.2?cm不等进行练习,训练操作者缉线时控制线与线之间的距离,保持平行的能力?/span></div> <div> <span style="font-size:14px;">(二)缉布训?/span></div> <div> <span style="font-size:14px;">准备白棉坯布、涤棉布等薄型零头面料;中厚型毛料、化纤、混纺等零头面料;较厚的毛呢、化纤、混纺等硬挺型面料零头;缝纫线;粗、中、细多种型号机针;锥子、镊子、纱剪等?/span></div> <div> <span style="font-size:14px;">1、直线缝?/span></div> <div> <span style="font-size:14px;">操作步骤如下?/span></div> <div> <span style="font-size:14px;">?)先将底线缠绕好,置于梭芯套内,拉出线头,装入梭床?/span></div> <div> <span style="font-size:14px;">?)再将缝纫面线按要求穿好,转动皮带轮,将底线勾出后上下线同时置于压脚下?/span></div> <div> <span style="font-size:14px;">?)将布料边缘按经纱向置于平缝机压脚前端?/span></div> <div> <span style="font-size:14px;">?)调整针距,打开电源开关,左右手分别置于布料前后位置,双脚轻轻踏动踏板,进行直线练习?/span></div> <div> <span style="font-size:14px;">?)在缝制中要学会选择机针型号和缝纫线的配用方法及压脚的调整?/span></div> <div> <span style="font-size:14px;">直线缝制应做到直、平、齐、准?/span></div> <div> <span style="font-size:14px;">2、弧线缝?/span></div> <div> <span style="font-size:14px;">弧线缝制较上线缝制难度增大,主要应通过脚、手、眼三者的协调配合,准确掌握缝制的缉缝操作?/span></div> <div> <span style="font-size:14px;">3、双线迹至多线迹的缝?/span></div> <div> <span style="font-size:14px;">首先练习缝制双线迹,要求线迹从始至终宽窄一致;然后再练习三线乃至多线的缝制?/span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">三、简单的故障与故障排?/span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">1、跳?/span></div> <div> <span style="font-size:14px;">原因:操作者由于经验不足在选用面料、针、线的匹配上不准确;机针未装正;或拉动布料过快等造成跳针?/span></div> <div> <span style="font-size:14px;">排除方法:正确选择和装针;缝制时左右手自然顺直?/span></div> <div> <span style="font-size:14px;">2、断?/span></div> <div> <span style="font-size:14px;">原因:主要是在缠绕梭芯时绕线太满,出线不爽,或上线穿错,张力太大,机针的位置不准确所致?/span></div> <div> <span style="font-size:14px;">排除方法:要保持松紧一致,上线在穿行过线器孔时要准确;安装机针时长容线槽朝机器正左方?/span></div> <div> <span style="font-size:14px;">3、断?/span></div> <div> <span style="font-size:14px;">原因:操作者不熟练,在拉动面料时用力太大造成?/span></div> <div> <span style="font-size:14px;">排除方法:随面自然前行?/span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">四、缝纫机安全使用注意事项</span></div> <div> <span style="font-size:14px;"> </span></div> <div> <span style="font-size:14px;">?? 必须遵守基本安全措施?/span></div> <div> <span style="font-size:14px;">?? 必须经过专业培训,对缝纫设备性能、特点、操作方法有较全面地学习与认识;</span></div> <div> <span style="font-size:14px;">?? 使用前应检查所有安全装置;</span></div> <div> <span style="font-size:14px;">?? 在安装机针、更换机针、压脚、针板、送布牙、弯针、旋梭或修理时,应立即关闭电源;</span></div> <div> <span style="font-size:14px;">??  离开缝纫机或工作场所时应关闭电源?/span></div> <div> <span style="font-size:14px;">?? 使用离合马达时,要等待马达完全停止后再进行;</span></div> <div> <span style="font-size:14px;">?? 缝纫机及附属装置使用的机油、润滑油等液体流入眼睛或沾到皮肤上应立即清洗?/span></div> <div> <span style="font-size:14px;">?? 禁止用手触摸缝纫机通电时的零件或装置;</span></div> <div> <span style="font-size:14px;">??有关工业用平缝机与包缝机的修理、改造、主要机构的调整由专门技术人员来进行?/span></div> <div> <span style="font-size:14px;">?0)一般的维修保养由专人进行;</span></div> <div> <span style="font-size:14px;">?1)在电气方面的修理应在电气技术员的监督和指导下进行;</span></div> <div> <span style="font-size:14px;">?2)缝纫机使用期间应定期清扫;</span></div> <div> <span style="font-size:14px;">?3)为了正常安全运转,应安装地线。同时应在不受高频焊接机等强噪声源影响的环境下使用;<br /> ?4)电源插头应由专人安装;</span></div> <div> <span style="font-size:14px;">?5)工业用平缝机、包缝机在指定用途以外不能使用?br /> <br />
