Description

一种挤出装置
技术领域
    本发明涉及通信现在制造设备领域，特别是涉及一种挤出装置。
背景技术
光导纤维，简称光纤，是一种光在玻璃或塑料制成的纤维中的全反射原理传输的光传导工具。微细的光纤封装在塑料护套中，使得它能够弯曲而不至于断裂。通常光纤的一端的发射设备使用发光二极管或一束激光将光脉冲传送至光纤，光纤的另一端的接收设备使用光敏组件检测脉冲。包含光纤的线缆称为光缆。由于光在光导纤维的传输损失比电在电线传导的损耗低得多，更因为主要生产原料是硅，蕴藏量极大，较易开采，所以价格便宜，促使光纤被用作长距离的信息传递工具。随着光纤制造工艺领域和制造设备领域的进一步优化或发展，现有光纤价格进一步降低，光纤在信号通讯线缆总所占比例正在迅速提高。
管棒法拉制光纤在现阶段仍是光纤拉丝工艺最常采用的重要方法。现有光纤的制造工艺和制造设备有两种：一是将熔炼成一体的芯/包预制棒直接在高温炉中加温软化拉制成光纤，如利用MCVD法制取的光纤预制棒；二是在芯层玻璃棒体上套上外包层玻璃管送入加热炉中熔炼成一体，再送入高温炉中加温软化拉制成光纤，如二步法生产的光纤芯层棒和包层管制成的预制棒。进一步优化现有光纤的制造工艺和制造设备，无疑会进一步提高现有光纤产品质量、提高光线产品的生产效率。
发明内容
针对上述现有技术中进一步优化现有光纤的制造工艺和制造设备，无疑会进一步提高现有光纤产品质量、提高光线产品的生产效率的问题，本发明提供了一种挤出装置。
为解决上述问题，本发明提供的一种挤出装置通过以下技术要点来解决问题：一种挤出装置，包括放线轮、收线轮、设置在放线轮与收线轮之间的塑料挤出机，所述塑料挤出机包括机座、螺旋挤出轮和位于螺旋挤出轮出口端的套塑座，所述套塑座上还设置有导向孔，螺旋挤出轮出口端与导向孔相交，所述套塑座内还设置有位于导向孔侧面的加热套，塑料挤出机与收线轮之间还设置有冷却槽。
具体的，设置的放线轮用于缠绕一次涂覆光纤，设置的收线轮用于缠绕套塑后的光纤，设置的导向孔作为一次涂覆光纤穿过套塑座的间隙，设置的螺旋挤出轮用于二次涂覆层向导向孔的挤出，在导向孔与螺旋挤出轮的相交处完成一次涂覆光纤与二次涂覆层塑料的汇合和涂覆复合。以上结构中，通过设置的加热套和冷却槽的结构特点，旨在实现对一次涂覆光纤或套塑光纤进行升温和降温，所述升温和降温即为将一次涂覆光纤升温至接近二次涂覆塑料的温度或降温至适宜二次涂覆光纤缠绕成卷的温度，以利于二次涂覆层的涂覆质量和本发明的加工效率。
更进一步的技术方案为：
作为一种盛料、热熔和挤出一体化结构，所述塑料挤出机还包括设置在机座上的料斗、位于料斗下方的加热室，所述螺旋挤出轮的入口端位于加热室的底部。
为便于二次涂覆光纤的线径控制，还包括测径仪，所述测径仪位于冷却槽的后方。
为便于实现二次涂覆光纤线径的自动控制，所述测径仪为激光测径仪，测径仪的输出端与收线轮的驱动装置控制模块和/或螺旋挤出轮的驱动装置控制模块电连接。
为利于二次涂覆质量，所述放线轮与套塑座之间还设置有紧线轮。
本发明具有以下有益效果：
本发明中，通过设置的加热套和冷却槽的结构特点，旨在实现对一次涂覆光纤或套塑光纤进行升温和降温，所述升温和降温即为将一次涂覆光纤升温至接近二次涂覆塑料的温度或降温至适宜二次涂覆光纤缠绕成卷的温度，以利于二次涂覆层的涂覆质量和本发明的加工效率。
