Description

一种全干式光纤带松套管及其制作方法 技术领域
本发明涉及通信领域，具体涉及一种全干式光纤带松套管及其制作方法。
背景技术
随着光纤入户覆盖规模的扩大和网络带宽的扩展，运营商对光纤光缆需求快速增长，而敷设光缆的城市地下管网资源有限；大芯数光纤带光缆因其光纤芯数多、外径小，很好的解决了上述矛盾，使得其需求增长迅速。而随着光缆制造行业的竞争日趋激烈，追求大芯数光纤带光缆结构的小型化，从而节省成本已成为必然趋势。
在现有光纤带松套管生产过程中，将光纤带螺旋放入松套管中，并在松套管中充入阻水油膏进行成型。阻水油膏可防止光纤带互相摩擦导致衰减；螺旋放入套管的方式可以保证光纤在松套管内余长，并保证后续生产的光缆弯曲和扭转性能更佳。而在生产中，如果阻水油膏充填过少会导致套管的圆度不均，致使松套管外径尺寸做小变得困难。
另外，在生产和施工过程中，现有光纤带松套管的油膏不仅难以清洁，而且对环境造成污染，保证干式光纤带松套管光缆生产过程清洁无污染，已成为光缆行业的发展方向。
发明内容
本发明所要解决的技术问题是由于阻水油膏充填过少会导致套管的圆度不均，致使现有光纤带松套管外径尺寸很难做小，且在生产和施工过程中现有光纤带松套管的油膏难以清洁，对环境造成污染的问题。
为了解决上述技术问题，本发明所采用的技术方案是提供一种全干式光纤带松套管，包括截面为圆形的松管套和光纤叠合体，
所述光纤叠合体由一根或多根光纤带叠合而成，每根所述光纤带外表面涂覆一层滑石粉；
所述光纤叠合体外表面周围设有阻水纱带，所述阻水纱带和所述光纤带叠合体螺旋状绞合敷设在所述松套管内。
在上述方案中，所述光纤带叠合体与阻水纱带在所述松套管内的绞合节距为300-800mm。
在上述方案中，所述阻水纱带包括沿光纤带叠合体中心对称设置上阻水纱带、下阻水纱带、左阻水纱带和右阻水纱带；
其中，上阻水纱带和下阻水纱带相同，对称分布在光纤带叠合体横向两侧，左阻水纱带和右阻水纱带相同，对称分布在光纤带叠合体竖向两侧。
在上述方案中，所述上阻水纱带、下阻水纱带、左阻水纱带和右阻水纱带的厚度相同；所述上阻水纱带和下阻水纱带宽度为光纤带叠合体横向宽度的三分之二；所述左阻水纱带和右阻水纱带的宽度为光纤带叠合体竖向宽度的三分之二。
本发明还提供了一种全干式光纤带松套管的制作方法，包括以下步骤：
光纤带由放纤绞笼逐步收拢螺旋放出，经其内部分线板分散后进入滑石粉盒，在每根光纤带表面涂覆滑石粉；
涂覆滑石粉的光纤带经过放纱绞笼，与放纱绞笼螺旋放出的阻水纱带一起进入叠带模；
光纤带和阻水纱带经过叠带模整形，输出螺旋状的光纤带叠合体；
光纤带叠合体螺旋进入挤出机，挤出圆形的松套管，冷却成型；
通过测径仪检测光纤带松套管的外直径是否符合生产标准，并记录不符合处；
经过测径仪的光纤带松套管通过牵引，由收线架盘起。
在上述方法中，所述放纤绞笼、放纱绞笼和叠带模同步旋转，且放纤绞笼和放纱绞笼的螺旋节距相同。
在上述方法中，所述叠合模中心设有一个对光纤带进行整形的整形孔，沿所述整形孔四周对称设置四个为阻水纱带定位的定位孔。
在上述方法中，所述整形孔为矩形孔，所述定位孔分为与整形孔的长和宽分别对应的上、下定位孔和左、右定位孔，其中，上、下定位孔和左、右定位孔的长度分别为整形孔的长和宽的三分之二。
本发明通过滑石粉和阻水纱带和阻水纱代替传统的阻水油膏，滑石粉可防止光纤带之间发生相对摩擦导致衰减和光纤带长时间接触发生粘连，阻水纱带中的吸水树脂遇水迅速膨胀，将光缆内部空隙填满，从而防止水在光缆内的纵向流动，在保证改良后的全干式光纤带松套管性能不受影响的前提下，使做小光纤带松套管外径尺寸成为可能，并且解决了在生产和施工过程中现有光纤带松套管的油膏难以清洁，对环境造成污染的问题。

本发明的松套管1制作材料为PBT、TPE、PC或GPP；光纤带叠合体与阻水纱带在松套管1内的绞合节距为300-800mm。
在本发明中，阻水纱带包括沿光纤带叠合体中心对称设置上阻水纱带4、下阻水纱带5、左阻水纱带6和右阻水纱带7；
其中，上阻水纱带4和下阻水纱带5相同，对称分布在光纤带叠合体横向两侧，左阻水纱带6和右阻水纱带7相同，对称分布在光纤带叠合体竖向两侧，这种阻水纱带的设置方式可以防止光纤带叠合体四角的四根光纤额外受力，导致其发生衰减；为保证阻水纱带吸水后能迅速填满松套管内部，防止水轴向流入松套管，上阻水纱带4、下阻水纱带5、左阻水纱带6和右阻水纱带7的厚度相同，上阻水纱带4和下阻水纱带5宽度为光纤带叠合体横向宽度的三分之二；左阻水纱带6和右阻水纱带7的宽度为光纤带叠合体竖向宽度的三分之二。
本发明的全干式光纤带松套管用滑石粉和阻水纱带代替传统的阻水油膏，滑石粉可防止光纤带之间发生相对摩擦导致衰减和光纤带长时间接触发生粘连，在光纤带叠合体四边放阻水纱，达到阻水效果，在保证全干式光纤带松套管性能不受影响的前提下，解决了现有光纤带松套管外径尺寸很难做小，以及在生产和施工过程中现有光纤带松套管的油膏难以清洁，对环境造成污染的问题。
如图2所示，本发明还提供了一种全干式光纤带松套管的制作方法， 具体包括以下步骤：
第一步、光纤带2由放纤绞笼S1先逐步收拢螺旋放出，在经其内部的分线板后呈散开状在态进入滑石粉盒S2，滑石粉盒S2中的内置喷头将滑石粉涂覆在每根光纤带表面；
第二步、涂覆滑石粉的光纤带2经过放纱绞笼S3，与放纱绞笼S3螺旋放出的阻水纱带一起进入叠带模S4；
第三步、光纤带2和阻水纱带经过叠带模S4整形后放出螺旋状的光纤带叠合体；
第四步、光纤带叠合体螺旋进入挤出机S5，采用挤管式成型的方式，挤出圆形的松套管1，并由履带牵引机S9牵引经过热水槽S6、热水箱S7、温水槽S8，最后进入冷水槽S10冷却成型；

在本发明中，放纤绞笼S1、放纱绞笼S3和叠带模S4同步旋转，且放纤绞笼S1和放纱绞笼S3的螺旋节距相同，以保证在叠带模S4输出的光纤带叠合体为螺旋状。
如图3所示，本发明的叠合模S4中心设有对光纤带2进行整形的整形孔S41，沿整形孔S41四周对称设置四个为阻水纱带定位的定位孔S42，以保证光纤带叠合体和四周阻水纱带的相对位置固定，防止阻水纱带缠绕在光纤带叠合体四角上的光纤，造成四角的四根光纤受力不均产生衰减。一般情况下，整形孔S41为矩形孔，使光纤带收拢成矩形的光纤带叠合体；定位孔S42分为与整形孔S41的长和宽分别对应的上、下定位孔和左、右 定位孔，其中，上、下定位孔和左、右定位孔的长度分别为整形孔的长和宽的三分之二长，避免四角的四根光纤受力不均产生衰减。

    涂覆滑石粉的光纤带经过放纱绞笼，与放纱绞笼螺旋放出的阻水纱带一起进入叠带模；
    光纤带和阻水纱带经过叠带模整形，输出螺旋状的光纤带叠合体；
    光纤带叠合体螺旋进入挤出机，挤出圆形的松套管，冷却成型；
    通过测径仪检测光纤带松套管的外直径是否符合生产标准，并记录不符合处；
    经过测径仪的光纤带松套管通过牵引，由收线架盘起。
  6. 如权利要求5所述的方法，其特征在于，所述放纤绞笼、放纱绞笼和叠带模同步旋转，且放纤绞笼和放纱绞笼的螺旋节距相同。
  7. 如权利要求5所述的方法，其特征在于，所述叠合模中心设有一个对光纤带进行整形的整形孔，沿所述整形孔四周对称设置四个为阻水纱带定位的定位孔。
  8. 如权利要求7所述的方法，其特征在于，所述整形孔为矩形孔，所述定位孔分为与整形孔的长和宽分别对应的上、下定位孔和左、右定位孔，其中，上、下定位孔和左、右定位孔的长度分别为整形孔的长和宽的三分之二。
