Description

一种涤纶长丝用加弹机 技术领域
本发明涉及涤纶长丝生产设备领域，特别是涉及一种涤纶长丝用加弹机。
背景技术
加弹机是各种涤纶长丝生产设备的重要组成部分之一。它可以将涤纶，锦纶等无捻丝，通过假捻变形加工成为具有中弹、低弹性能的弹力丝的一种纺织机械。在加弹过程中，有一个步骤是在变形热箱中进行的。申请号为CN201610247356的发明专利申请公开了一种加弹机接触式变形热箱，热箱主体上端面与热轨上端面相吻合，并且热箱主体的上端面与热轨的凸面之间留有间隙。使得热门与热轨之间的空隙尽量减小，减少散热。但是间隙是可观存在的，依然会有热量的散失，若间隙过小则容易出现热门不发关闭的情况，并且在制造过程中对热门和热轨的精度要求也随之提高，大大提升了制造成本。
发明内容
本发明针对上述技术问题，克服现有技术的缺点，提供一种涤纶长丝用加弹机，在箱体工作过程中的热量散失少，节能性更好。
为了解决以上技术问题，本发明提供一种涤纶长丝用加弹机，包括热箱主体，热箱主体一端开口且开口内安装有热轨，热箱开口端通过热门封闭，热门朝向热轨的一面设有反射膜。
技术效果：当热轨在工作过程中热量传递给热门，此时热量的传递方式为热辐射，因为反射膜可以反射掉93％以上的辐射热，所以即将散失的热量通过反射膜又被重新反射回热轨上，使得热轨的热量不易从热门处散失掉；
在热门与热轨之间的间隙大小一定的情况下，这种热辐射的反射来进行保温的效果更好。并且可以适当增加间隙的大小，也可达到原有的降低热量损失，节能的效果。使得本方案的一种涤纶长丝用加弹机，不但可以更加节能，并且热门与热轨之间的间隙大小，也可以相对较大一些。从而使得热门与热轨的加 工精度相对降低，从而降低了加工成本。
本发明进一步限定的技术方案是：
进一步的，反射膜朝向热轨的一侧设有透明玻璃，且透明玻璃为耐高温玻璃制成。
前所述的一种涤纶长丝用加弹机，热轨朝向热门的面为弧形面，透明玻璃朝向弧形面的一侧为与弧形面相匹配的圆弧面。
前所述的一种涤纶长丝用加弹机，透明玻璃连接反射膜的面为曲面。
前所述的一种涤纶长丝用加弹机，反射膜与热门之间设有气凝胶毡隔热层。
前所述的一种涤纶长丝用加弹机，热轨两侧分别设有石膏板。
前所述的一种涤纶长丝用加弹机，热轨底部为岩棉层。
前所述的一种涤纶长丝用加弹机，岩棉层与热轨之间设有石棉层。
前所述的一种涤纶长丝用加弹机，石膏板外侧设有岩棉层，且岩棉层与石膏板之间设有石棉层。
前所述的一种涤纶长丝用加弹机，石膏板两端向远离滑轨的方向弯折并将岩棉层与石棉层包裹住。
本发明的有益效果是：
(1)本发明中反射膜的主要成分为铝箔，可以通过蒸发式真空镀膜技术、磁控溅射真空镀膜或凝胶浸渍镀膜等工艺将铝箔附着在透明玻璃上，从而保证反射膜表面光滑，反射性能更好。并且长时间处于高温的工作状态中，透明玻璃形成了反射膜的保护层，使得反射膜可以更加长久的持续使用；
(2)本发明中透明玻璃为耐高温玻璃，可以长时间工作在350℃～850℃的高温工作环境中。且耐高温玻璃的厚度一般在2～30mm之间，空间占用小，质量小。所以不易对热门的开关造成较大的负荷。耐高温玻璃长时间处于高温工作 状态中不易发生形变。相对于对比文件来说，由于热门与热轨长时间处于高温状态中时，均易发生形变，从而使得二者之间的间隙不易过小，从而使得较多的热量散失。本方案中耐高温玻璃长时间处于高温工作状态中，不易发生形变，或者形变量很小，甚至而已忽略不计。使得热轨的形变成为影响二者之间间隙大小的主要因素。所以本方案可以使热门与热轨之间的间隙更小，从而使得热轨在工作过程中的热量散失的更少，使得加弹机更加节能；
(3)本发明中使高温玻璃与热轨的形状相匹配，使得二者之间的距离可以变得更小，从而使得热轨在工作过程中的热量散失的更少，使得加弹机更加节能；
(4)本发明中气凝胶毡的导热系数低，耐高温性能强，由于气凝胶毡本身柔软，可以适应并贴合在透明玻璃曲面上的反射膜上。因为热门本身为平面，与曲面的透明玻璃之间形成的空间形状不规则，因为气凝胶毡柔软易裁剪，从而可以填充满透明玻璃与热门之间的空间。当铝箔温度变高时，不易将热量传递出去；
(5)本发明中石膏板具有重量轻、隔音效果好、隔热性能强、加工性能强的特点。而且本方案中只需将石膏板夹在热轨与热箱主体之间。在加工制造时需要将石膏板加工的较厚，使得石膏板夹在热轨与热箱主体之间时可以与热轨贴合的更加紧密。使得对热轨的保温性能更好；
(6)本发明中通过石棉将岩棉层与热箱主体、热轨之间的间隙填充满。使得热轨在工作过程中产生的热量不易散失。石棉的防火、绝缘和保温性能强。并且具有良好的隔音效果；
(7)本发明中岩棉层可以将石膏板与岩棉层之间的间隙填充满，并且将石膏板压在热轨上。使得较大的空隙变成若干较小的空气团。防止热轨的热量散失。

如图2所示，热门3通过合页14转动连接在热箱主体1上。
结合图8，热箱主体1上设有排烟通道18，因为涤纶等纤维在进入一种涤纶长丝用加弹机之前经过浸油处理，所以在加热过程中会产生油烟，排烟通道18帮助一种涤纶长丝用加弹机排出油烟。
