Description

多层复合套筒
技术领域
本发明属于高分子复合材料技术领域，具体涉及一种多层复合套筒。
背景技术
随着装备制造业的发展，印刷行业和橡胶工业发展迅猛，尤其是在柔版印刷机设备领域。同时人们对各种印刷产品的质量越来越重视，从单色发展到多色、套色，因而对印刷胶辊的性能也提出了更高的要求，表面耐磨、耐溶剂、光洁度高、尺寸稳定性好等均成为人们关注的重点。目前传统的印刷胶辊尚不能完全适应这些条件要求。
多层复合套筒是专为柔版印刷机配套关键部件，其采用多种高分子材料复合而成，发挥各层件的作用特性，再与气胀芯轴的紧密配合下完成柔版印刷作业。
发明内容
本发明的目的是提供一种多层复合套筒，其内骨架层和骨架层为玻纤树脂材质，赋予套筒整体一定的弹性，便于与气胀芯轴装配，质量小，强度高，在高速印刷过称中安全、可靠。
本发明所采用的技术方案是，多层复合套筒，结构为柱形，截面为圆环形；从外到内依次为外层、填充层、骨架层、缓冲层和内骨架层，其中外层为热塑性材料或硬质橡胶，填充层为聚氨酯或橡胶硬质发泡层，骨架层和内骨架层为玻纤树脂材质，缓冲层为软质橡胶或聚氨酯发泡海绵。
本发明的特点还在于，
多层复合套筒通过压缩空气压力安装于气胀芯轴上，形成过盈配合。
外层为热塑性材料或硬质橡胶，其硬度为100邵尔A。
填充层为聚氨酯或橡胶硬质发泡材料，其密度为0.4～0.55g/cm3，硬度为95～100邵尔A。
骨架层和内骨架层厚度为1.0～2.2mm，耐温>160℃，在4.5kg/cm2压力下，内径变化不大于0.05％。
缓冲层为聚氨酯或橡胶发泡海绵，厚度为1.4～1.8mm，耐温>160℃，硬度为20～30邵尔A，密度为0.15～0.25g/cm3。
本发明的有益效果是，
1.本发明采用多层复合结构，利用和发挥高分子材料的特性，与气胀芯轴的紧密配合完成柔版印刷作业。
2.本发明采用了玻纤、树脂、橡胶、聚氨酯多种材料，采用了软质闭孔发泡、硬质闭孔发泡技术及缠绕、固化、混炼、挤出、硫化、车、磨、抛光等工艺实现了多层复合套筒高强度、轻量化、可靠性设计。
附图说明
图1是气胀芯轴的结构图；
图2是本发明多层复合套筒的结构图；
图3是本发明多层复合套筒与气胀芯轴的装配图。
图中，1.气胀芯轴，2.多层复合套筒，3.内骨架层，4.缓冲层，5.骨架层，6.填充层，7.外层，8.气孔，9.米拉阀。
具体实施方式
下面结合附图和具体实施方式对本发明进行详细说明。
如图1所示，气胀芯轴1，芯轴与多层复合套筒2接触面的起端均匀分布6个进气孔8，中间与末端安装了2个米拉阀9，确保安装或拆换方便。整个气胀芯轴1尺寸一致，避免了锥度引起的高速运转过程中的跳动，保证了气胀芯轴1与多层复合套筒2的紧密配合为一体，确保柔印机高速运转过程中的安全、可靠性。
如图2所示，本发明多层复合套筒，为柱形结构，截面为圆环形，从外到内依次为外层7、填充层6、骨架层5、缓冲层4和内骨架层3。
外层7为热塑性材料，如热塑性聚氨酯；或外层为硬质橡胶。外层7直接与印刷材料接触，要求外层表面光洁度高、耐磨、耐溶剂。其外层7通过车、磨、抛光工艺达到以上要求。
填充层6为硬质、闭孔发泡的聚氨酯或橡胶材质，其质量小，强度高，密度为0.4～0.55g/cm3，硬度为95～100邵尔A。
骨架层5和内骨架层3为玻纤树脂材料，内骨架层3与气胀芯轴1紧密配合。骨架层5和内骨架层3作为骨架在套筒中起支撑作用，其厚度为1.0～2.2mm，耐温>160℃，在4.5kg/cm2压力下，内径变化不大于0.05％。骨架层5和内骨架层3采用预浸树脂的玻璃纤维通过缠绕设备缠绕成筒状结构，再经过高温固化而成。
缓冲层4为软质、闭孔发泡聚氨酯或橡胶材质，其为内骨架层3、骨架层5提供弹性应变空间，在气压下，便于与气胀芯轴1装配。其厚度为1.4～1.8mm，耐温>160℃，硬度为20～30邵尔A，密度为0.15～0.25g/cm3。
如图3所示，为多层复合套筒2和气胀芯轴1的装配图，在4～5kg/cm2压力下，多层复合套筒2安装在气胀芯轴1上，关闭压力，完成安装。然后去掉进气管路，多层复合套筒2将紧紧与气胀芯轴1配合为一体。
