具体实施方式
以下所述仅为本发明的较佳实施例， 并不因此而限定本发明的保护范围。 实施例， 见图 1至图 4所示： 一种中空柱状结构复合板材的生产设备， 包括机架 1、用于连续性挤出第一面板的第一螺杆挤出机 2以及用于连续性挤 出第二面板的第二螺杆挤出机 3，第一螺杆挤出机 2和第二螺杆挤出机 3分别 设置有一挤出模头 4。生产设备包括一用于在第一面板的表面吸塑定型出若干 互不相连的中空薄壁拉伸体并将第一面板和第二面板复合成一复合板材的复 合辊组 5， 第一螺杆挤出机 2、 复合辊组 5和第二螺杆挤出机 3依次设置在机 架 1的第一侧， 第一螺杆挤出机 2的挤出模头 4和第二螺杆挤出机 3的挤出 模头 4分别设置在复合辊组 5的两侧的邻近位置。 第一螺杆挤出机 2的挤出 模头 4和第二螺杆挤出机 3的挤出模头 4分别设置有一挤出口， 挤出口的宽 度沿复合辊组 5的轴向方向延伸， 第一螺杆挤出机 2的挤出模头 4横向穿设 于机架 1。它可以生产三层结构的复合板材， 复合板材由上至下依次为第一面 板、 中空薄壁拉伸体和第二面板， 各中空薄壁拉伸体的两端部分别连结于第 一面板和第二面板。
第二螺杆挤出机 3的挤出模头 4接近于第一复合辊 51和第二复合辊 52 的压合处， 第二螺杆挤出机 3挤出的第二面板从挤出口到第一复合辊 51和第 二复合辊 52的压合处的长度大幅度缩小， 避免第二面板在输送到压合处之前 被过度冷却， 第二面板不易受外界因素影响， 温度容易控制， 提高第二面板 的熔接性能。
第一螺杆挤出机 2的挤出模头 4的挤出口接近于第一真空定型辊 53与第 一复合辊 51的压合处。 第一螺杆挤出机 2挤出的第一面板从其挤出口到第一 真空定型辊 53与第一复合辊 51 的压合处的长度大幅度缩小， 使第一面板暴 露在外的长度非常短， 避免第一面板在输送到压合处之前被过度冷却， 第一 面板到达复合辊组 5 处之后再通过真空吸塑工艺定型出中空位伸体， 成型出 来的中空的薄壁拉伸体从第一真空定型辊 53脱模后马上与第二面板复合， 由第一螺杆挤出机 2的挤出模头 4和第二螺杆挤出机 3的挤出模头 4到 复合辊组 5 的距离大致相同， 并且距离大幅减小， 各个挤出机挤出的板材到 压合处的长度大幅度缩小， 第一螺杆挤出机 2挤出的第一面板和第二螺杆挤 出机 3挤出机挤出的第二面板到复合辊组 5的压合处的距离大致相同， 第一 面板和第二面板的收缩率相同， 复合性能较好， 生产出来的复合板材平整度 较高， 产品质量好。
另外， 避免第一面板的中空的薄壁拉伸体输送到压合处之前被过度冷却， 并且第一面板在到达复合辊组 5才成型出中空的薄壁拉伸体， 第一面板及其 薄壁拉伸体的温度不易受外界因素影响， 温度容易控制， 还能避免变形， 提 高第一面板和中空的薄壁拉伸体的熔接性能， 经复合辊组 5压合熔接后的复 合板材的结合度更高， 其结构强度更高。
再者， 本发明只有一个复合辊组 5， 减少复合辊的数量， 也不需要设置牵 引装置输送第一面板， 结构更简单， 降低设备成本。 复合辊组 5包括一第一真空定型辊 53、 第一复合辊 51和第二复合辊 52， 第一真空定型辊 53用于在第一面板的表面吸塑定型出若干互不相连的中空薄 壁拉伸体的， 第一复合辊 51和第二复合辊 52压合配合， 第一复合辊 51和第 二复合辊 52的辊面间隙配合， 第一真空定型辊 53设置于第一复合辊 51的旁 侧， 第一真空定型辊 53的辊面与第一复合辊 51的辊面间隙配合。

内真空辊套 531 的轴腔的两端分别连接于冷却回路中， 内真空辊套 531 和外成型辊套 532均为硬质的薄壁结构， 第一复合辊 51和第二复合辊 52平 行设置， 第一复合辊 51和第二复合辊 52的辊面选用有软材质的辊面。 便于 成型， 并且不损坏板材。
于较佳实施方式中， 生产设备还包括用于连续性挤出第三面板的第三螺 杆挤出机 6， 第三螺杆挤出机 6置有一挤出模头 4， 第三螺杆挤出机 6的挤出 模头 4位于第一螺杆挤出机 2的挤出模头 4的下方， 第三螺杆挤出机 6的挤 出模头 4设置在复合辊组 5的邻近位置。 复合辊组 5包括一用于在第三面板 的表面吸塑定型出若干互不相连的中空薄壁拉伸体的与第一真空定型辊 53结 构相同的第二真空定型辊 54， 第二真空定型辊 54设置于第二复合辊 52的旁 侧， 第二真空定型辊 54的辊面与第二复合辊 52的辊面间隙配合。 第一螺杆 挤出机 2和第三螺杆挤出机 6分别设置在机架 1第一侧的两旁侧位置。 第三 螺杆挤的挤出模头 4横向穿设于机架 1，第三螺杆挤的挤出模头 4接近于第二 真空定型辊 54和第二复合辊 52的压合处。 它可以生产五层结构的复合板材， 复合板材由上至下依次为第一面板、 中空薄壁拉伸体、 第二面板、 中空薄壁 拉伸体和第三面板， 第一面板和第二面板的夹层空间内的各中空薄壁拉伸体 的两端部分别连结于第一面板和第二面板， 第二面板和第三面板的夹层空间 内的各中空薄壁拉伸体的两端部分别连结于第二面板和第三面板。
第三螺杆挤出机 6挤出的第三面板从挤出口到第二真空定型辊 54和第二 复合辊 52的压合处的长度大幅度缩小， 第三面板暴露在外的长度非常短， 于 优选实施方式中， 第一螺杆挤出机 2和第三螺杆挤出机 6对称设置。
由第一螺杆挤出机 2的挤出模头 4到第一真空定型辊 53和第三螺杆挤出 机 6的挤出模头 4到第二真空定型辊 54的距离大致相同， 并且第三螺杆挤出 机 6的挤出模头 4到第二真空定型辊 54的距离和第二螺杆挤出机 3的挤出模 头 4到复合辊组 5的距离大致相同， 并且其距离大幅减小， 三个螺杆挤出机 挤出的板材到压合处的长度大幅度缩小， 距离大致相同， 第三螺杆挤出机 6 挤出的第三面板到复合辊组 5的压合处的距离和第二螺杆挤出机 3挤出机挤 出的第二面板到复合辊组 5 的压合处的距离大致相同， 第一面板、 第二面板 和第三面板的收缩率大致相同， 复合性能较好， 生产出来的复合板材平整度 较高， 产品质量好。
另外， 第三面板到达复合辊组 5 处之后才通过真空吸塑工艺定型出中空 位伸体， 成型出来的中空的薄壁拉伸体从第二真空定型辊 54脱模后马上与第 二面板复合， 避免第三面板及其中空的薄壁拉伸体输送到压合处之前被过度 冷却， 第三面板及其薄壁拉伸体的温度不易受外界因素影响， 温度容易控制， 还能避免变形， 提高第三面板和中空的薄壁拉伸体的熔接性能， 经复合辊组 5 压合熔接后的复合板材的结合度更高， 其结构强度更高。
