Description

一种高效传动的缝纫机 技术领域
本申请涉及缝纫机技术领域，尤其涉及一种高效传动的缝纫机。
背景技术
缝纫机作为布料的缝制机器已有两百多年发展历史，为人类社会服装业的发展作出了贡献，推动了人类社会文明发展。在缝纫机的机械传动***中，主轴电机对整个缝纫机的运转提供动力，较为通用的动力分配方案是在缝纫机的机头内部设置有主传动轴，在主传动轴中间部分设置同步轮或者锥齿轮组将动力传递到缝纫机基板下，目的是实现对缝纫下线输出任务；在主传动轴的末端则是对针滑动杆的上下运作提供动力。例如，中国专利文献中，专利号为CN2019103855413于2019年6月28日公开的名为一种模板缝纫机，包括机壳、底座、机头总成、旋梭组件，所述机壳包括立柱部及悬臂部，所述机头总成与上转轴固定连接，上转轴转动连接在上箱体内，所述旋梭组件与下转轴固定连接，上转轴、下转轴分别通过上同步带、下同步带与竖轴连接，所述竖轴直接或间接由电机驱动转动带动旋梭组件、机头总成同步转动，在上同步带的一侧或两侧分别设置有对上同步带进行张紧的张紧机构，所述上箱体滑动连接在固定板上，固定板固设在悬臂部的左端部，在固定板上设置有升降气缸，升降气缸的活塞杆与上箱体连接，当升降气缸带动机头总成向上移动时，张紧机构解除对上同步带的张紧，上同步带的一端随着机头总成一起向上移动，当升降气缸带动机头总成向下移动复位后，张紧机构对上同步带进行张紧。
现有缝纫机的这种机械传动存在着传动效率低，缝纫机制造难度高，机械磨损大噪音高等缺陷。另外在缝制时，各传动部件都需要添加润滑脂，特别是高速度运转的旋梭，因其与主轴的速比是2:1，旋梭运转时通常处于8000转/分钟转速，需要对旋梭添加适量的润滑油，在此难免会对缝制用线及布料产生污染。
发明内容
针对现有缝纫机在机械传动中存在的上述传动效率低、旋梭高速运转需要添加润滑油的缺陷，本申请打破常规缝纫机设计理念，推出并生产出一种高效传动的缝纫机，通过对悬臂部和基板独立设置，并实施各自的动力源，并且本申请的旋梭不需要润滑油无接触不磨损高寿命优点，不需要匹配复杂的变速齿轮组，具有应用方便，造价低、智能化程度高的好处。
为了实现上述发明目的，本发明采用以下技术方案。
一种高效传动的缝纫机，包括悬臂部、基板和缝纫电控，其特征在于，所述悬臂部内部设有执行上线缝制的动力源一，所述基板下部设有执行下线缝制任务的动力源二，所述悬 臂部与基板分别通过动力源一和动力源二独立传动设置，所述动力源二包括用于带动旋梭执行缝制的缝纫电机；所述旋梭包括线架、勾针和旋梭固定座，所述旋梭固定座的内腔中设有悬浮梭芯，线架设置在悬浮梭芯的内腔中，线架与悬浮梭芯转动连接线架通过悬浮梭芯实现与旋梭固定座的转动连接，勾针设置在旋梭固定座外侧，勾针与旋梭固定座之间具有间隙，缝纫电机带动勾针绕旋梭固定座的外圆周运动。本申请通过将缝纫机设为两个独立体的悬臂部和基板，并实施各自的动力源，各自动力源具有的若干个电机在缝纫电控下进行程序化控制，提高了缝纫控制的智能化水平，特别是上述提到的基板下部安装的缝纫电机用于直接带动旋梭来执行缝制；悬浮梭芯及其线架配置在固定式的旋梭固定座内腔，缝纫电机带动勾针再勾上机针的上线，带动线架出线这个过程无接触无摩擦，使得本申请的勾线悬浮旋梭运转不需要与现有技术一样以高速运转来实现缝制工作，实现了本申请勾线悬浮旋梭的静态工作，也使得应用本申请的勾线悬浮旋梭的缝纫设备具有更加优良机械传动效能。
作为优选，悬臂部固定在缝纫机上方，所述基板固定在缝纫机的下方。悬臂部和基板构成缝纫机，可以设置立柱用于架线，也可以不设置立柱部，在不设置立柱部时，悬臂部和基板组成缝纫机，使得大块布料或者不易折叠的布料在本缝纫机上可以顺利实现缝制，具有较高的实用性。
作为优选，缝纫机还包括立柱部，所述立柱部下段连接基板，所述立柱部上段连接悬臂部。立柱部支撑连接基板和悬臂部上可以架设电源线束等静态部件；方便设备集成。

具体实施方式
下面结合附图和具体实施例对本实用新型进行进一步的阐述，以使本申请的优点和特征能更易于被本领域技术人员理解，从而对本申请的保护范围做出更为清楚明确的界定,这些实施方式仅用于说明本发明，而并非对本发明的限制。
实施例1，
如图1到8所示，一种高效传动的缝纫机具有悬臂部11、基板20和缝纫电控(图中未标出)，悬臂部11内部设有执行上线缝制的动力源一，基板20下部设有执行下线缝制任务的动力源二，所述臂部与基板分别通过动力源一和动力源二之间没有机械传动部件独立传动设置，也就是悬臂部11与基板20之间没有机械传动部件，没有比如传动轴、同步带、上下移动部件 或者摆动件等等带机械传动的部件设置。悬臂部11内部具有的动力源一与基板20下部具有动力源二由缝纫电控控制，在此基础上，利用缝纫电控达到对动力源一和动力源二的控制，上述的动力源一和动力源二可以是一个电机或者是数个电机，上述悬臂部11内部具有的动力源一和基板20下部具有动力源二受缝纫电控程序化控制，使得本申请的缝纫机缝制的智能化进一步提高。
进一步的，上述基板20下部安装的动力源二包括用于直接带动旋梭来执行缝制的缝纫电机。
上述立柱部12设置在悬臂部11与基板20之间，立柱部12起到固定连接悬臂部11与基板20的作用，由于在悬臂部11和基板20各安装有执行缝纫的电机，因此立柱部12在本申请中可有可无。在有设置立柱部12时，立柱部12下接基板20上连悬臂部11，可以在立柱部12上架设电源线束等静态部件；当不设置立柱部12时，悬臂部11固定在缝纫机上方，基板20固定在缝纫机的下方构成缝纫机，使得大块布料或者不易折叠的布料在本缝纫机上可以顺利实现缝制，具有较高的实用性。在不设置立柱部12时，悬臂部11和基板20组成机头1，在设置立柱部时，悬臂部11、立柱部12和基板20组成了机头1。
所述旋梭，如图2到图5所示，具有缝纫电机91、旋梭固定座3、悬浮梭芯7、机针2、定位连接杆92、线架6和勾针5。本申请的旋梭固定座3为固定式，即旋梭固定座3连接定位连接杆92，在缝制过程中旋梭固定座3及其定位连接杆92是静止不动的，定位连接杆92间接或者直接固定在缝纫机头1的基板20上，机针2具有勾线处21，用于勾针5勾线。
本申请的缝纫电机91具有中空主轴911，中空主轴911为动力输出轴，定位连接杆92穿过中空主轴911，中空主轴911与定位连接杆92之间设置有轴承93。缝纫电机91与定位连接杆92为动连接，缝纫电机91固定在基板20下侧，缝纫电机91的中空主轴911连接带动勾针5运转。上述定位连接杆92与线架6同轴设置。
上述勾针5直接连接缝纫电机91，或者，作为另外的实施方式勾针5与缝纫电机91之间设置有连接体，使得缝纫电机91带动勾针5运转。
设置在旋梭固定座3底部方向的缝纫电机91以定位连接杆92为中心轴带动勾针5作圆周运转，可以根据不同缝制设备的要求调整设置旋梭固定座3的安装位置和角度。
上述旋梭固定座3具有防滑出挡板31，上述旋梭固定座3具有防滑出前挡板31，上述防滑出前挡板31安装到旋梭固定座3时根据线架6的使用情况可有可无，本实施例以设有防滑出前挡板31为例来说明，具体是：防滑出挡板31安装在旋梭固定座3的侧部或者端部。上述防滑出挡板31以盖板的形式设置固定在旋梭固定座3上，防滑出挡板31在缝制过程中 抵靠悬浮梭芯7和/或线架6上，起到对上述悬浮梭芯7和线架两者的横向定位。这里本申请的旋梭固定座3和防滑出挡板31的连接方式为弹簧铰链式，也可以设置为定位连接，用手向边侧一推就可以实现防滑出挡板31的开或关。另外，上述防滑出挡板31设置在缝纫电机91带动勾针5运转的范围之外。
上述旋梭固定座3具有可容纳悬浮梭芯7的内腔，悬浮梭芯7具有可容纳线架6的内腔，具体是上述线架6放置在悬浮梭芯7的内腔，悬浮梭芯7和线架6放置在旋梭固定座3的内腔，实际是悬浮梭芯7连同线架6一起放置进去，取出时，悬浮梭芯7和线架6从旋梭固定座3的内腔拿出。悬浮梭芯7与旋梭固定座3之间具有定位设置和滑线间隙，旋梭固定座3还具有下线引出孔。
上述定位设置具体是：如图4所示，上述悬浮梭芯7还具有定位凸块71，定位凸块71设置在靠近旋梭固定座3一侧；旋梭固定座3还具有定位槽32，定位槽32与定位凸块71相匹配设置。当悬浮梭芯7放置在旋梭固定座3的内腔时，悬浮梭芯7的定位凸块71定位在旋梭固定座3的定位槽32内，定位凸块71起到对悬浮梭芯7定位在旋梭固定座3的作用，保证了悬浮梭芯7的放置位置，也保证悬浮梭芯7与旋梭固定座3之间具有的自由滑线间隙。
上述滑线间隙是指：悬浮梭芯7具有分线凸台72、前凸块75、滑线斜面73和滑线平面74，滑线斜面73和滑线平面74位于分线凸台72的两侧，上述悬浮梭芯7的滑线斜面73朝向旋梭固定座3具有的内圆弧面33，内圆弧面33与滑线斜面73相对具有滑线间隙，滑线平面74与防滑出挡板31相对具有滑线间隙，分线凸台72作用在于滑线分线，让缝制用线在勾针5带动下一从滑线斜面73滑过，二从滑线平面74滑过，勾针5在悬浮梭芯7具有的分线凸台72圆周外侧随动力输入源运转。前凸块75设置在分线凸台72的前端，前凸块75具有的机针定位孔槽711，前凸块75设置有下线引出槽76。由于上述悬浮梭芯7与旋梭固定座3之间具有滑线间隙，利于缝制用线从分线凸台72绕过滑线。
上述勾针5在悬浮梭芯7具有的分线凸台72圆周外侧随动力输入源运转，并处于勾线处21的相切面上，机针2平行于线架6，勾针5处于勾线处21的相切面上，本实施例以机针2平行于线架6(平行于线架6的侧边)来说明。
上述勾针5与悬浮梭芯7及悬浮梭芯7之间是无接触勾线分线配合工作。先将线架6放置到悬浮梭芯7的内腔，再将悬浮梭芯7连同线架6一起放入旋梭固定座3，定位凸块71要按在定位槽32上，盖上防滑出挡板31，防滑出挡板31抵靠在悬浮梭芯7和/或线架6前部，同时使得防滑出挡板31抵靠在悬浮梭芯的滑线平面74；分线凸台72上的滑线斜面73与旋梭固定座3相对，使得缝制用线在分线凸台72两侧的滑线平面74和滑线斜面73滑过，构成 自由滑线间隙，实现了缝制用线在本申请的一种勾线悬浮旋梭上无接触勾线分线的技术效果。本申请的旋梭固定座3相对于现有技术的旋梭在运行方式上是不同，本申请的旋梭固定座3在缝制时是静态的，是在无接触无磨损的情况下进行缝制勾线的。
在缝制结束时，防滑出挡板31仍处在关闭状态，即防滑出挡板31还与悬浮梭芯7的滑线平面74相对。要拿出用完缝制用线的线架6时，将防滑出挡板31推开，线架6就可以从悬浮梭芯7中取出；要装入线架6时，向将线架6放置在悬浮梭芯7的内腔并引好下线，盖上防滑出挡板31即可开始缝制工作；要取出悬浮梭芯7则要将防滑出挡板31推开，悬浮梭芯7连同线架6一起从旋梭固定座3内腔取出。
结合附图，本申请的勾针5设置在旋梭固定座3外侧，所述前凸块75的机针定位孔槽711供机针2前端运转，勾针5在缝纫电机91的带动下勾住处于外侧机针2的勾线处21上的上线。勾针5连接缝纫电机91，勾针5在缝纫电机91的带动产生相应的勾线运动轨迹，与机针2协调运转起到勾线的缝制目的。机针2的上线1a进行缝制勾线，勾针5对上线1a的拉力带动悬浮梭芯7的线架6输出线源。在缝纫电机91运转下，勾针5与机针2相互协调，使得在缝制过程中线架6所需较低转速就可以实现缝纫出线，而旋梭固定座3和悬浮梭芯7处于静态，克服了现有缝纫机技术中对旋梭高速运转的要求。
如图6到图8所示，旋梭在使用时，先将下线1d引到下线引出槽76，当机针2带着上线1a穿过布料，到达悬浮梭芯7的机针定位孔槽711后，动力输入源带动勾针5在勾线处21并勾取上线1a，被勾取上线1a由悬浮梭芯7的分线凸台72分线分为前线和后线，勾针5继续旋转到大于180度到达脱线位1c开始脱线。同时，机针2拉着上线1a继续收线，将环绕在悬浮梭芯7上的上线1a收紧并套住下线1d完成缝纫。
实施例2，
在图9中，本实施例二与上述的实施例一基本相同，不同之处在于实施例一的机针2垂直于线架6，还具有针板8，上述所述机针2的前端在针板8上具有的针板孔81运作，机针2垂直于针板8，针板8处于勾针5及悬浮梭芯7的上方，勾针5处于勾线处21的相切面上。机针2带着上线1a穿过针板8进入到最初勾线状态，上述机针2的针尖部分运行在针板8中，机针2在悬浮梭芯7外侧的针板8下进行工作，勾针5与悬浮梭芯7及悬浮梭芯7之间是无接触勾线分线配合工作，勾针5在悬浮梭芯7具有的分线凸台72圆周外侧随动力输入源运转，上述勾针5的方向与实施例一不同，实现的勾线过程是一样的，上述方案与实施例一一样起到相同的技术效果，也应该属于本申请的保护范围。
以上所述仅为本申请的优选实施方式，并非因此限制本申请的专利范围，凡是利用本 申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本申请的专利保护范围内。
