另一个实施例，内筒200的下端设有安装座220，第三轴承423远离第二轴承座421的一端贴合安装座220。通过设置安装座220，使内筒200能进行快速的固定安装， 提高立体卷铁心变压器绕线料筒的安装便利性。
另一个实施例，安装座220上均匀设置有多个安装孔221。通过设置安装孔221，提高内筒200的安装稳定性，避免立体卷铁心变压器绕线料筒发生偏转的情况。
另一个实施例，外筒100包括上壳110和下壳120；上壳110和下壳120通过连接环130固定连接。通过设置上壳110、下壳120和连接环130，能根据材料的高度调整连接环130的高度，使外筒100的高度与材料一致，提高立体卷铁心变压器绕线料筒的通用性。
另一个实施例，上壳110和下壳120远离连接环130的一侧均设置有向外延伸的挡板140。通过设置挡板140，使外筒100对材料起到引导安装的作用，避免材料在传送过程中发生偏移的情况。
下面对本发明的工作原理做进一步说明。
在使用前，首先根据材料的规格，比如箔带或层间纸的长度、高度和厚度，选择不同尺寸的连接环130，保证外筒100的高度与箔带或层间纸的缠绕高度一致，使料筒能装载不同宽度、厚度的箔带或层间纸；把张力组件300和内筒200依次安装在下壳120内，然后通过连接环130连接上壳110和下壳120；接着把材料均匀、紧密地卷绕在外筒100上，位于外筒100上下端的挡板140起限位的作用，避免箔带或层间纸在卷料过程中发生松动和偏移的情况；最后通过安装座220和安装孔221把外筒100设置在绕线模具中，完成绕线的上料操作。当绕线模具开始运转，带动料筒上的箔带或层间纸往外传送，进而带动外筒100绕内筒200的轴线转动；同时，外筒100带动传动部333和第二轴承座421转动，由于弹簧320的两端分别贴合螺杆310和固定部331，固定部331通过摩擦部332对传动部333施加压力，使摩擦部332与传动部333产生摩擦力，从而使外筒100对传送中的箔带或层间纸产生张力，达到控制材料传送速度和保证绕线质量的效果；另外，由于螺杆310穿过固定部331并与螺孔240螺纹连接， 操作者能通过调整孔311改变螺杆310与固定部331的相对位置，进而改变弹簧320作用在固定部331上的压力，从而改变摩擦部332与传动部333之间的摩擦力，实现对外筒100张力的快速调整；在生产过程中，根据绕线效果调整张力，能有效提高绕线质量和效率。在送料过程中，由于外筒100通过上连接部410和下连接部420与内筒200连接，内筒200上通过套设第一轴承412、第二轴承422和第三轴承423，进一步保证了外筒100与内筒200的同轴度，避免发生外筒100位移和脱落的情况，提高绕线料筒送料的稳定性；外筒100上的箔带或层间纸始终保持在挡板140之间，挡板140起到导向的作用，避免了箔带或层间纸在送料过程中发生偏移和脱落的情况。
从以上的描述可以看出，本发明的立体卷铁心变压器绕线料筒通过设置外筒100和内筒200，缠绕在外筒100上的箔带或层间纸能随着外筒100的转动，稳定、快速地向外传送，提高了立体卷铁心产品的绕线效率；通过设置张力组件300，当在传动部333在外筒100的带动下转动时，摩擦部332与传动部333产生摩擦力，进而使外筒100对箔带或层间纸施加张力，避免发生箔带或层间纸发生脱位的情况，保证线圈质量；通过设置螺纹和调整孔311，便于改变螺杆310与内筒200的位置，进而调整外筒100对箔带或层间纸施加的张力大小，提高立体卷铁心变压器绕线料筒的通用性和使用便利性；通过设置上壳110、下壳120和连接环130，能根据材料的高度调整连接环130的高度，使外筒100的高度与材料一致，提高立体卷铁心变压器绕线料筒的通用性。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
