Description

一种卷心管及其制备方法
技术领域
本发明涉及条材技术领域，更具体地说，涉及一种卷心管，以及一种卷心管的制备方法。
背景技术
现有技术中，如图1所示，卷心管通过ABS注塑制得，其中，内管芯与外管芯之间通过支撑结构进行连接支撑。常见结构的卷心管为一体式结构，采用挤出器挤出成型，则支撑结构沿卷心管的长度方向无断开，制备时的物料成本较高；如果需要将支撑结构在卷心管的长度方向上形成断开，则需要设置另一台挤出设备，设备投入大，制备成本较高。
另一方面，每种规格的卷心管，包括内外管芯的直径不同、内外管芯之间的强度不同，等等，均需要对应一种规格的卷心管开一套特定的注塑模具，模具成本极高；而且，各种规格的注塑模具不能共用，整体的生产成本无法进一步降低。
发明内容
本发明的目的在于克服现有技术的不足，提供一种卷心管及其制备方法，满足物料成本低、制备成本低、注塑模具可通用等需求，能够从整体上降低生产成本。
本发明的技术方案如下：
一种卷心管，包括内管芯、外管芯，内管芯设置于外管芯内，内管芯的外侧套设若干管内套件，管内套件填充于内管芯与外管芯之间，内管芯固定在外管芯内；所述的管内套件包括EPE芯材、两片EPE面材，两片EPE面材分别设置于EPE芯材的第一表面与第二表面，EPE面材的硬度大于EPE芯材的硬度。
作为优选，EPE面材的密度为100kg/m3-110kg/m3，EPE芯材的密度为25kg/m3-28kg/m3。
作为优选，EPE面材与EPE芯材之间、内管芯的外侧与管内套件的内侧壁之间、外管芯的内侧与管内套件的外卷面之间，通过热熔胶粘合固定。
作为优选，热熔胶的软化温度大于100℃。
作为优选，若干管内套件间隔套设于内管芯的外侧。
作为优选，包括至少三个管内套件，内管芯或外管芯的两端分别设置至少一个管内套件，内管芯与外管芯的中部位置设置至少一个管内套件。
作为优选，EPE面材与EPE芯材为HDPE发泡制得。
作为优选，管内套件为圆环结构，内管芯与外管芯同轴固定。
一种卷心管的制备方法，包括如下步骤：
1)内管芯的外侧表面涂布热熔胶；
2)将管内套件套设于内管芯的外侧；
3)将管内套件的外卷面涂布热熔胶；
4)将外管芯套设于管内套件的外卷面，通过热熔胶固定。
作为优选，管内套件的制备方法为：先制备夹心片材，所述的夹心片材包括EPE芯材、两片EPE面材，两片EPE面材分别设置于EPE芯材的第一表面与第二表面；再对应内管芯的外径与外管芯的内径冲压夹心片材，得到管内套件。
本发明的有益效果如下：
本发明所述的卷心管，通过将EPE制得的管内套件填充并粘合于内管芯与外管芯之间，对内管芯进行固定，整体生产成本低；并可根据实际使用需求，调节管内套件的EPE芯材与EPE面材的密度，即可改变卷心管的参数性能。基于本发明的结构，只需要对应设置不同规格的内管芯、外管芯的注塑模具、管内套件的冲压模具，即可分别生产并组合成不同规格的卷心管，模具的通用性大大提高。
管内套件间隔设置，可根据实施需求设置管内套件的数量，保证卷心管的强度的同时，节约成本；并且管内套件的设置位置可根据卷心管的长度调整，适用于制备任意尺寸的产品。
本发明所述的卷心管的制备方法，内管芯、外管芯、管内套件分别预备，再通过热熔胶粘合为一体，生产设备与注塑模具通用性强，便于制备不同规格的产品，大大降低设备投入。

具体实施方式
以下结合附图及实施例对本发明进行进一步的详细说明。
本发明为了解决现有技术存在的生产成本高、模具成本高、规格不通用的问题，提供一种卷心管，如图2、图3所示，包括内管芯11、外管芯10，内管芯11设置于外管芯10内，内管芯11的外侧套设若干管内管件20，管内管件20填充于内管芯11与外管芯10之间，内管芯11固定在外管芯10内。本实施例中，管内管件20为圆环结构，内管芯11与外管芯10同轴固定。
如图4、图5所示，所述的管内管件20包括EPE芯材21、两片EPE面材22，两片EPE面材22分别设置于EPE芯材21的第一表面与第二表面，形成夹心式结构。EPE面材22的硬度大于EPE芯材21的硬度。本发明中，EPE面材22在硬度上大于EPE芯材21，在保证管内管件20的强度的同时，可降低管内管件20的物料成本。如果管内管件20为单一材质，即EPE芯材21与EPE面材22的硬度相同，如果硬度过低时，管内管件20的强度无法达到实施要求，如果提升硬度至管内管件20的强度达到实施要求，则成本较高。
本实施例中，EPE面材22与EPE芯材21为HDPE发泡制得，即高密度聚乙烯HDPE发泡制得的EPE珍珠棉(聚乙烯发泡棉)，对应于EPE芯材21与EPE面材22的硬度，通过发泡倍数进行控制，发泡倍率越小，EPE密度越大，硬度越高；反之硬度越低。本发明中，EPE面材22的密度为100kg/m3-110kg/m3，EPE芯材21的密度为25kg/m3-28kg/m3，本实施例中，EPE面材22的密度为100kg/m3，EPE芯材21的密度为25kg/m3，保证管内管件20获得足够强度的情况下，成本尽可能降低。
本发明采用热熔胶粘合的方式进行装配，具体地，EPE面材22与EPE芯材21之间、内管芯11的外侧与管内管件20的内侧壁之间、外管芯10的内侧与管内管件20的外卷面之间，通过热熔胶粘合固定。其中，选用耐高温的热熔胶，以满足高温工作环境的要求，本实施例中，热熔胶的软化温度大于100℃，优选地，可选用软化温度大于140℃的功能性热熔胶。通过功能性热熔胶进行粘合装配，只需要通过控制温度即可完成，方便高效。
为了平衡成本与性能，本实施例中，若干管内管件20间隔套设于内管芯11的外侧。具体地，包括至少三个管内管件20，内管芯11或外管芯10的两端分别设置至少一个管内管件20，内管芯11与外管芯10的中部位置设置至少一个管内管件20。具体实施时，也可以根据需求增加管内管件20的数量与间隔，且管内管件20的间隔可为不等间距。
本发明还提供一种卷心管的制备方法，将内管芯11、外管芯10、管内管件20分别预备，再组合为一体，具体包括如下步骤：
1)内管芯11的外侧表面涂布热熔胶；
2)将管内管件20套设于内管芯11的外侧；
3)将管内管件20的外卷面涂布热熔胶；
4)将外管芯10套设于管内管件20的外卷面，通过热熔胶固定。
其中，管内管件20的制备方法为：先制备夹心片材，所述的夹心片材包括EPE芯材21、两片EPE面材22，两片EPE面材22分别设置于EPE芯材21的第一表面与第二表面；再对应内管芯11的外径与外管芯10的内径冲压夹心片材，得到管内管件20。冲压得到的管内管件20的中心位置为适配内管芯11的通孔，管内管件20的外轮廓适配外管芯10。
上述实施例仅是用来说明本发明，而并非用作对本发明的限定。只要是依据本发明的技术实质，对上述实施例进行变化、变型等都将落在本发明的权利要求的范围内。
