Description

一种重组竹型材及其生产工艺 技术领域
本发明涉及新材料新型高性能纤维制备技术领域，具体是指一种重组竹型材及其生产工艺。
背景技术
竹重组型材通常是将竹材截断、剖分、制丝或分层制篾、干燥、浸胶、竹篾或竹丝全纵向组坯、热压后而制成的一种密度大、强度高的结构用材，近年来得到了广泛的应用。
竹重组型材目前被广泛应用在户外地板、户外墙板、花园地板、型材板以及马厩板等领域，竹重组材作为实木板材中的一种，随着其他实木板材被不断消耗，日渐短缺，其可再生制造的特性深受各大家具生产厂商的追捧，目前已经在实木板材中占据了不少的份量。
上述各种重组竹型材在生产时由于竹料和胶水之间均匀度很难控制的很好，使得实际制造成型的重组竹型材在品质均匀性上相对不是特别好，存在改进空间，基于此，本发明人对此问题深入研究，遂有本案产生。
发明内容
本发明的主要目的在于提供一种重组竹型材，以解决现有技术中所形成的重组竹型材品质一致性较差的问题。
为了达成上述目的，本发明的解决方案是：
一种重组竹型材，其中，所述重组竹型材由浸胶的竹丝束组成，每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖，相邻竹丝束之间由胶水填充，所述竹丝束经过碾压疏解、碳化、烘干、浸胶、干燥、养生、压制、板坯再养生、定厚、造型和油漆之后形成重组竹型材。
进一步，所述竹丝束和胶水之间的干重量比为5：10-100。
进一步，所述胶水为水溶性树脂。
本发明还提供一种重组竹型材的生产工艺，其中，包括如下步骤：
①碾压疏解：采用竹龄在5年以上的优质毛竹，经去青去黄之后在碾压设备中将竹篾碾压疏解成竹丝束，每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖；
②碳化：将竹丝束中的淀粉、糖分和蛋白质分解并杀死虫卵和真菌；
③烘干：将竹丝束的含水率控制在8％；
④浸胶、干燥和养生：采用水溶性树脂对烘干后的竹丝束进行浸胶处理，再一次经过干燥控制含水率在8％范围，再将带有胶水的竹丝束在堆置在空气中进行养生处理，以让竹丝束中各处的水分能够实现自动平衡；
⑤压制和板坯再养生：采用超过2700吨热压机进行热压成型，竹丝束与水溶性树脂充分连接之后固化成型，取出重组竹板坯；再将重组竹板坯进行堆置再养生，让重组竹板坯中的水分自然均衡；
⑥定厚、造型、油漆、打包和装柜。
进一步，所述步骤③采用烘干设备进行烘干处理，所述烘干设备具有底座、蒸汽加热盘管、支撑盘以及上罩，所述蒸汽加热盘管由高导热材料制成并具有蒸汽入口和蒸汽出口，所述支撑盘架设在底座和蒸汽加热盘管上，所述支撑盘具有带透气孔的支撑台以及呈环形绕设在支撑台四周的围栏，所述上罩罩设在底座上以将待烘干的竹丝束、支撑盘以及蒸汽加热盘管均罩设在内部，所述上罩顶部还形成有真空抽气孔。
进一步，所述步骤⑥采用真空喷涂装置来实现快速油漆，所述真空喷涂装置具有第一输送机构、第二输送机构、雾化油墨腔、底部烘干机构和顶部烘干机构，所述第一输送机构和第二输送机构等高并排间隔设置，所述雾化油墨腔设置在第一输送机构和第二输送机构之间，所述第一输送机构将板坯输送至第二输送机构，所述雾化油墨腔内充满有雾化油漆，所述雾化油墨腔上还形成有板坯进口和板坯出口，所述第一输送机构和第二输送机构之间最小间距小于板坯的宽度，所述底部烘干机构位于第二输送机 构的入口处用于将板坯下表面的油漆进行烘干处理，所述顶部烘干机构位于第二输送机构的上方以对板坯其它表面进行烘干处理。
进一步，所述步骤①中的碾压设备具有上压头和下撑座，所述上压头和下撑座之间形成有若干根导柱，所述下撑座上表面形成有若干个竹篾容纳槽，所述上压头在对应每个竹篾容纳槽处都形成有若干根尖刺条，不同竹篾容纳槽上方的尖刺条在数量和排布方式上均相同。
进一步，对应每个竹篾容纳槽上方的若干个尖刺条构成为一组，每组尖刺条都分为呈轴对称的左侧部和右侧部，左侧部和右侧部的尖刺条横截面均为直角三角形，所述左侧部的尖刺条将竹篾往左侧挤压，所述右侧部的尖刺条将竹篾往右侧挤压。
进一步，所述左侧部和右侧部中相邻两根尖刺条之间的距离均是越朝外间距越宽。
采用上述方案后，本发明涉及的一种重组竹型材及其生产工艺，其由于每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖，即不存在完全断裂镂空的问题，如此胶水在每一竹丝束的引导下，在整个重组竹型材长度方向会更加均匀，进而让整个重组竹型材的品质可以保持恒定，确保了实际使用型材时的便利性。
此外，本发明采用两次养生的方式成型，让整个型材中的各种成分均能实现自动均衡，大大提升了产品的一致性，满足了高品质型材的需求。

具体实施方式
下面结合附图和具体实施方式对本案作进一步详细的说明。
如图1和图3所示，本发明涉及的一种重组竹型材，所述重组竹型材100由浸胶的竹丝束组成，每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖，相邻竹丝束之间由胶水填充，所述竹丝束经过碾压疏解、碳化、烘干、浸胶、干燥、养生、压制、板坯再养生、定厚、造型和油漆之后形成重组竹型材。
其中，所述竹丝束和胶水之间的干重量比为5：10-100。
优选地，所述胶水为水溶性树脂。
如此，本发明涉及的一种重组竹型材及其生产工艺，其由于每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖，即不存在完全断裂镂空的 问题，如此胶水在每一竹丝束的引导下，在整个重组竹型材长度方向会更加均匀，进而让整个重组竹型材的品质可以保持恒定，确保了实际使用型材时的便利性。此外，本发明采用两次养生的方式成型，让整个型材中的各种成分均能实现自动均衡，大大提升了产品的一致性，满足了高品质型材的需求。
如图2所示，本发明还提供一种重组竹型材的生产工艺，包括如下步骤：
①碾压疏解：采用竹龄在5年以上的优质毛竹，经去青去黄之后在碾压设备50中将竹篾碾压疏解成竹丝束，每一竹丝束均沿着重组竹型材的纤维长度方向连续覆盖；
②碳化：将竹丝束中的淀粉、糖分和蛋白质分解并杀死虫卵和真菌；
③烘干：将竹丝束的含水率控制在8％；
④浸胶、干燥和养生：采用水溶性树脂对烘干后的竹丝束进行浸胶处理，再一次经过干燥控制含水率在8％范围，再将带有胶水的竹丝束在堆置在空气中进行养生处理，以让竹丝束中各处的水分能够实现自动平衡；
⑤压制和板坯40再养生：采用超过2700吨热压机进行热压成型，竹丝束与水溶性树脂充分连接之后固化成型，取出重组竹板坯40；再将重组竹板坯40进行堆置再养生，让重组竹板坯40中的水分自然均衡；
⑥定厚、造型、油漆、打包和装柜。
如图3至图6所示，其为本发明中烘干工艺的一种具体实施例，所述步骤③采用烘干设备20进行烘干处理。
如图3至图6所示，所述烘干设备20具有底座21、蒸汽加热盘管22、支撑盘23以及上罩24，所述蒸汽加热盘管22由高导热材料制成并具有蒸汽入口221和蒸汽出口222，所述支撑盘23架设在底座21和蒸汽加热盘管22上，所述支撑盘23具有带透气孔233的支撑台231以及呈环形绕设在支撑台231四周的围栏232，所述上罩24罩设在底座21上以将待烘干 的竹丝束、支撑盘23以及蒸汽加热盘管22均罩设在内部，所述上罩24顶部还形成有真空抽气孔241。
如此，在真空抽气孔241的作用下，整个上罩24内部会形成由下往上的热气流，具体是在上部真空负压的作用下，从下部渗入的空气首先经过蒸汽加热盘管22的加热，加热后的空气会对竹丝束60进行烘干，由于竹丝束60是呈竖立状态，使得加热后的空气和竹丝束之间有较长的接触时间，确保了热能利用率，提升了烘干的效果。
如图7所示，其为本发明的优选实施例，所述步骤⑥采用真空喷涂装置30来实现快速油漆。
所述真空喷涂装置30具有第一输送机构31、第二输送机构32、雾化油墨腔33、底部烘干机构34和顶部烘干机构35。
所述第一输送机构31和第二输送机构32等高并排间隔设置，所述雾化油墨腔33设置在第一输送机构31和第二输送机构32之间，所述第一输送机构31将板坯40输送至第二输送机构32。
所述雾化油墨腔33内充满有雾化油漆，所述雾化油墨腔33上还形成有板坯40进口和板坯40出口，所述第一输送机构31和第二输送机构32之间最小间距小于板坯40的宽度，所述底部烘干机构34位于第二输送机构32的入口处用于将板坯40下表面的油漆进行烘干处理，所述顶部烘干机构35位于第二输送机构32的上方以对板坯40其它表面进行烘干处理。
如此，第一输送机构31在输送板坯40时，板坯40的前端会先离开第一输送机构31而进入到雾化油墨腔33中，由于雾化油墨腔33中充满雾化的油墨，当板坯40进入之后，板坯40表面会自动覆盖上油墨，随着第一输送机构31的不断输送，当板坯40快要进入到第二输送机构32时，板坯40底部会被底部烘干机构34烘干并由第二输送机构32来承接，最后再由第二输送机构32实现对板坯40的输送，在由第二输送机构32进 行输送的过程中，所述顶部烘干机构35会对板坯40进行除了底部之后的其他侧面进行烘干，如此本发明可以快速实现烘干，大大提升了烘干效率。
如图8和图9所示，作为碾压设备50的一种较佳实施例，所述步骤①中的碾压设备50具有上压头51和下撑座52，所述上压头51和下撑座52之间形成有若干根导柱53，所述下撑座52上表面形成有若干个竹篾容纳槽521，所述上压头51在对应每个竹篾容纳槽521处都形成有若干根尖刺条511，不同竹篾容纳槽521上方的尖刺条511在数量和排布方式上均相同。优选地，所述尖刺条511均固定在活动座512上，所述活动座512通过弹簧513连接在上压头51上。
在实际使用时，需将不同的竹篾放置在不同的竹篾容纳槽521中，然后再由碾压设备50的的上压头51向下压下，由于数量和排布方式相同，如此确保了竹篾上间隙的一致性，避免了在碾压过程中竹篾上间隙的随意成型，进而确保了产品的一致性，提高整个重组竹型材的品质。
优选地，对应每个竹篾容纳槽521上方的若干个尖刺条511构成为一组，每组尖刺条511都分为呈轴对称的左侧部和右侧部，左侧部和右侧部的尖刺条511横截面均为直角三角形，所述左侧部的尖刺条511将竹篾往左侧挤压，所述右侧部的尖刺条511将竹篾往右侧挤压。
优选地，所述左侧部和右侧部中相邻两根尖刺条511之间的距离均是越朝外间距越宽。如此正好和竹篾本身对称的圆弧状相匹配，让展开后的竹篾上的更加均匀。
以上所述仅为本发明的优选实施例，凡跟本发明权利要求范围所做的均等变化和修饰，均应属于本发明权利要求的范围。
