本发明涉及利用连续压机加工人造板、板状坯料等板材技术领域，尤其涉及一种压制纤维板的方法及采用该方法压制纤维板的连续压机。
背景技术
参见图1和图2，连续压机100具有一个压制机上部110和一个压制机下部120，还具有在压制机上部110和压制机下部120内连续运转的上、下钢带130、140以及上、下辊杆链毯150、160，在压制机上部110和压制机下部120内分别设置有上、下进给热压板170、180，上、下钢带130、140在进入上、下进给热压板170、180之间的位置处形成一进料轮廓191。上、下进给热压板170、180之间形成一压料通道192。压料通道192的进料端与进料轮廓191呈自然过渡连接。
工作时，环绕在上从动辊筒131和上驱动辊筒132的上钢带130和环绕在下从动辊筒141和下驱动辊筒142的下钢带140在上、下驱动辊筒132、142的驱动下作循环运动，将待压制的纤维坯料200随着上、下钢带130、140循环运动而被送进由上、下钢带130、140之间形成的进料轮廓191内，再进入到由上、下进给热压板170、180之间形成的压料通道192并经后续压制通道193中被压制成各种规格的纤维板材。
为了使上、下钢带130、140与上、下进给热压板170、180之间形成滚动摩擦，减小运行阻力，工作时，环绕在上链毯驱动链轮151和上链毯从动链轮152的上辊杆链毯150和环绕在下链毯驱动链轮161和下链毯从动链轮162的下辊杆链毯160在上、下链毯驱动链轮151、161的驱动下也作循环运动，进入到上、下进给热压板170、180与上、下钢带130、140之间。
通常来说，在上、下进给热压板170、180中配置有上、下加热装置(图中未示出)，上、下加热装置将热量通过上、下进给热压板170、180、上、下辊杆链毯150、160和上、下钢带130、140传递至压料通道192内的待压制的纤维坯料200中，使待压制的纤维坯料200中的胶粘剂固化，同时压制机上部110上的加压装置111对上、下进给热压板170、180施加压力，并通过上、下辊杆链毯150、160和上、下钢带130、140传递至压料通道192内的待压制的纤维坯料200中，将纤维坯料200逐步压实至预先设定的厚度，并经后续压制通道193，最终形成纤维板被送出。
上、下进给热压板170、180之间的压料通道192是可以被调整的，以使一台连续压机100能够压制厚度不同的纤维板材，如12mm、16mm、25mm厚度的纤维板材。
目前的连续压机100的上、下进给热压板170、180只有一个温度区域，待压制的纤维坯料200由进料轮廓191进入压料通道192内进行固化压制过程中，由于受到高温高压，纤维板材的上、下表面会形成一层预固化层。通常来说，压制成型后的纤维板材的上、下表面需要进行砂光处理，去掉纤维板材的上、下表面的预固化层，最终使出厂的纤维板材在整个横截面上的硬度基本趋于一致(如图3所示)。例如对于压制成型后且去除预固化层的最终厚度为12mm的纤维板材而言，上、下表面的预固化层的厚度将达到0.45mm，即连续压机100压制出的纤维板材厚度将达到12.9mm。如此厚的预固化层意味着：1、原材料浪费严重，使得制造成本高；2、砂光量大，磨削用的砂带消耗和砂光设备电耗大大增加；3、砂光产生大量的粉尘，处理工作量大，同时也带来安全问题。
压制成型后的纤维板材的上、下表面的预固化层的厚度，除了与纤维状态和纤维中施加的胶粘剂的性能有关以外，与待压制的纤维坯料200的进料速度、待压制的纤维坯料200在压制过程中受到上、下进给热压板170、180的 压制温度和压制压力有关。待压制的纤维坯料200在一定的进料速度和压制温度的情况下，待压制的纤维坯料200受到上、下进给热压板170、180的压制压力越低，压制成型后的纤维板材的上、下表面的预固化层越厚，反之，待压制的纤维坯料200受到上、下进给热压板170、180的压制压力越高，压制成型后的纤维板材的上、下表面的预固化层就越薄。业界内的技术人员通常是通过加大压制压力来降低压制成型后的纤维板材的上、下表面的预固化层的厚度，然而这种方法会导致在压制成型后的纤维板材上形成粉尘斑。
因为待压制的纤维坯料200在固化压制过程中，需要释放大量的气体，这些释放出来的大量气体一方面从压料通道192的两侧排出，另一部分由于压料通道192后端的纤维坯料200已经逐步固化并被压实，只能向进料轮廓191方向排出(如图4和图5所示)，向进料轮廓191方向排出的这部分气体会在上、下钢带130、140与待压制的纤维坯料200接触的位置产生旋涡气流，旋涡气流作用于待压制的纤维坯料200的上、下表面并产生大量的粉尘团10，尤其是待压制的纤维坯料200的下表面(如图6所示)，而这些粉尘团10又被带入压料通道192内，由于这些粉尘团10受到高温气流的影响往往使粉尘团中的胶粘剂提前固化，无法融合到待压制的纤维坯料200中而在压制成型的纤维板材的表面形成了粉尘斑。
目前为了解决压制成型的纤维板材上的粉尘斑的问题，通常是将上进给热压板170在靠近压料通道192进口的位置即图7的Ⅰ处位置提升一定的高度，使上进给热压板170与纤维坯料200的进入方向形成“S”型曲面，使得在压制时上进给热压板170与下进给热压板180之间在I处位置形成一排气缝隙194，待压制的纤维坯料200在固化压制过程中所产生的大量气体经由该排气缝隙194向两侧排出，这样就有效地减少了向进料轮廓191方向排出的这部分气体的流量，迫使向进料轮廓191方向排出的这部分气体无法在上、下钢带130、140与待压制的纤维坯料200接触的位置产生旋涡气流，因而有效地减 少粉尘团的产生量或者避免粉尘团的产生，另外这种做法可以提高进料速度，提高产量。但是，这种做法会增加压制成型后的纤维板材表面的预固化层的厚度。
上述问题一直困扰着业界，也是业界技术人员一直想要解决的。
发明内容
本发明所要解决的技术问题之一在于针对现有连续压机压制纤维板材所存在的不足之处而提供一种利用连续压机压制纤维板的方法，采用该方法压制的纤维板材其预固化层得到较大幅度减小，节约了原材料，降低了砂光量和粉尘，减少粉尘团的产生，避免在压制成型后的纤维板材的表面形成粉尘斑。
本发明所要解决的技术问题之二在于提供一种采用上述方法压制纤维板的连续压机。
作为本发明第一方面的一种压制纤维板的方法，其是环绕在上驱动辊筒和上从动辊筒的上钢带和环绕在下驱动辊筒和下从动辊筒的下钢带在上、下驱动辊筒的驱动下作循环运动，将待压制的纤维坯料随着上、下钢带循环运动而被送进由上、下钢带之间形成的进料轮廓内，再进入到由上、下进给热压板之间形成的压料通道内压制成纤维板材；其特征在于，所述压料通道分为正常压制的固化区域和压制但不固化区域，待压制的纤维坯料先进入所述压制但不固化区域再进入所述正常压制的固化区域，当待压制的纤维坯料经过所述压制但不固化区域的过程中，待压制的纤维坯料的厚度被压缩但其中的胶粘剂未固化。
在本发明的一个优选实施例中，所述压制但不固化区域所设定的温度和待压制的纤维坯料通过的时间不足于待压制的纤维坯料的胶粘剂正常固化的温度和需要的时间。
在本发明的一个优选实施例中，所述压制但不固化区域所设定的温度低于纤维坯料的胶粘剂在通过所述压制但不固化区域时需要的正常固化的温度。
在本发明的一个优选实施例中，所述压制但不固化区域的温度低于纤维坯料的胶粘剂在通过所述压制但不固化区域时需要的正常固化的温度是通过对所述压制但不固化区域进行冷却实现的。
在本发明的一个优选实施例中，所述压制但不固化区域的温度低于纤维坯料的胶粘剂在通过所述压制但不固化区域时需要的正常固化的温度是通过不对上、下钢带在经过所述压制但不固化区域过程中进行加热实现的。
在本发明的一个优选实施例中，所述压制但不固化区域的压力与所述正常压制的固化区域的压力相等或低于所述正常压制的固化区域的压力。
在本发明的一个优选实施例中，所述上进给热压板靠近所述压料通道的进口的位置提升一定的距离，使得在压制时上、下进给热压板之间在靠近所述压料通道的进口的位置形成一排气缝隙。
作为本发明第二方面的采用上述方法压制纤维板的连续压机，具有一个压制机下部和一个压制机上部，还具有在压制机下部和压制机上部内连续运转的上、下钢带以及上、下辊杆链毯，在压制机下部和压制机上部内分别设置有上、下进给热压板，上、下钢带在进入上、下进给热压板之前的位置处形成一进料轮廓，所述上、下进给热压板之间形成一压料通道，所述压料通道与所述进料轮廓连接，其特征在于，所述压料通道分为正常压制的固化区域和压制但不固化区域，待压制的纤维坯料先进入所述压制但不固化区域再进入所述正常压制的固化区域，当待压制的纤维坯料经过所述压制但不固化区域的过程中，待压制的纤维坯料的厚度被压缩但其中的胶粘剂未固化。
在本发明的一个优选实施例中，所述压制但不固化区域所设定的温度和待压制的纤维坯料通过的时间不足于待压制的纤维坯料的胶粘剂正常固化的温度和需要的时间。
在本发明的一个优选实施例中，所述压制但不固化区域所设定的温度低于纤维坯料的胶粘剂在通过所述压制但不固化区域时需要的正常固化的温度。
在本发明的一个优选实施例中，所述上、下进给热压板之间的区域分为第一温度控制区域和第二温度控制区域，其中所述上、下进给热压板上的第一温度控制区域对应于所述压制但不固化区域，所述上、下进给热压板上的第二温度控制区域对应于所述正常压制的固化区域。
在本发明的一个优选实施例中，所述上、下进给热压板之间的第一温度控制区域和第二温度控制区域分别进行单独控制。
在本发明的一个优选实施例中，所述压制但不固化通道的温度低于纤维坯料的胶粘剂在通过所述压制但不固化区域时需要的正常固化的温度是通过不对上、下钢带在经过所述压制但不固化区域过程中进行加热实现的。
在本发明的一个优选实施例中，所述压制但不固化区域的压力与所述正常压制的固化区域的压力相等或低于所述正常压制的固化区域的压力。
在本发明的一个优选实施例中，所述上进给热压板靠近所述压料通道的进口的位置提升一定的距离，使得在压制时上、下进给热压板之间在靠近所述压料通道的进口的位置形成一排气缝隙。
待压制的纤维坯料由进料轮廓进入正常压制的固化区域前，首先进入到一压制但不固化区域，这样纤维坯料中的空气可以在压制但不固化区域内向两侧和进料轮廓方向排出，同时正常压制的固化区域中的纤维坯料在压制固化过程中产生的气体一方面从正常压制的固化区域的两侧排出，另一部分则通过压制但不固化区域排出，由于压制但不固化区域内的胶粘剂没有被固化，气体可以顺利的排出，最终使得压制后的纤维板材上、下表面的预固化层的厚度相对于现有技术至少可减少30％～40％，甚至只有现有技术的30％，从而较大幅度地节约了原材料，减少了砂光量和降低了砂光设备电耗和砂带的消耗，降低了砂光产生的粉尘。
另外，由于待压制的纤维坯料经过压制但不固化区域时的胶粘剂没有达到完全固化，纤维坯料在正常压制的固化区域所释放的气体可以经由压制但不固 化区域向进料轮廓方向排出，而这部分气体不足以在上、下钢带与待压制的纤维坯料接触的位置产生旋涡气流，即使产生了旋涡气流，使得待压制的纤维坯料的上、下表面产生了其胶粘剂并未固化的粉尘团，而这些粉尘团被带入压制但不固化区域内，由于待压制的纤维坯料的胶粘剂在压制但不固化区域内没有形成固化，这些粉尘团可以融合在待压制的纤维坯料的表面，从而避免了纤维板材的表面形成粉尘斑。
其次，由于将上进给热压板在靠近压料通道的进口的位置提升了一定的高度，使得在压制时上、下进给热压板之间在靠近压料通道的进口的位置形成一排气缝隙，那么待压制的纤维坯料在压制但不固化区域内所产生的气体以及在正常压制的固化区域所产生的且向压制但不固化区域排放的大量气体可以通过该排气缝隙向纤维坯料的两侧排出，有效地减少了向进料轮廓方向排出的气体的流量，避免形成漩涡气流，这样就可以适当地加快进料速度，提高产量。

具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本发明。
参见图1和图2，本发明的连续压机与现有的连续压机大致相同，同样具有一个压制机下部110和一个压制机上部120，还具有在压制机下部110和压制机上部120内连续运转的上、下钢带130、140以及上、下辊杆链毯150、160，在压制机下部110和压制机上部120内分别设置有上、下进给热压板170、180，上、下钢带130、140在进入上、下进给热压板170、180之前的位置处形成一进料轮廓191，上、下进给热压板170、180之间形成一压料通道192。
本发明的连续压机与现有的连续压机不同之处在于：参见图8，上、下进给热压板170、180之间形成的压料通道分为正常压制的固化区域192b和压制但不固化区域192a，正常压制的固化区域192b通过该压制但不固化区域192a与进料轮廓191连接，即待压制的纤维坯料先进入压制但不固化区域192a再进入正常压制的固化区域192b。压制但不固化区域192a所设定的温度和待压制的纤维坯料200通过的时间不足于待压制的纤维坯料200中的胶粘剂正常固化的温度和需要的时间，因而，当待压制的纤维坯料200经过压制但不固化区域192a的过程中，待压制的纤维坯料200的厚度被压缩但其中的胶粘剂未固化。具体地，压制但不固化区域192a的温度应当低于待压制的纤维坯料200 的胶粘剂在通过压制但不固化区域192a时需要的正常固化的温度。
为了能够实现压制但不固化区域192a的温度低于待压制的纤维坯料200的胶粘剂在通过压制但不固化区域192a时需要的正常固化的温度，可以通过对压制但不固化区域192a进行冷却实现。具体地，将上、下进给热压板170、180之间的区域分为第一温度控制区域310和第二温度控制区域320，并且第一温度控制区域310和第二温度控制区域320分别进行单独控制，如图9所示，其中，上、下进给热压板170、180的第一温度控制区域310对应于压制但不固化区域192a，上、下进给热压板170、180上的第二温度控制区域320对应于正常压制的固化区域192b。
此外，实现压制但不固化区域192a的温度低于待压制的纤维坯料200的胶粘剂在通过压制但不固化区域192a时需要的正常固化的温度的方式还可以为：通过不对上、下钢带130、140在经过压制但不固化区域192a过程中进行加热，因为上、下钢带130、140从压料通道192的出口端伸出后做循环运动又重新从压料通道192的进口端进入压料通道192内，在此过程中，上、下钢带130、140由于没有受到加热装置加热作用已得到了冷却，上、下钢带130、140的温度大大降低，因而通过适当地调整即可保证上、下钢带130、140重新进入压料通道192内时的温度低于待压制的纤维坯料200的胶粘剂在通过压制但不固化区域192a时需要的正常固化的温度。
本发明的连续压机进行压制纤维坯料的工作如下：环绕在上驱动辊筒和上从动辊筒的上钢带130和环绕在下驱动辊筒和下从动辊筒的下钢带140在上、下驱动辊筒的驱动下作循环运动，将待压制的纤维坯料200随着上、下钢带130、140循环运动而被送进由上、下进给热压板170、180之间形成的进料轮廓191内，并依次通过压制但不固化区域192a，即第一温度控制区域310和正常压制的固化区域192b，即第二温度控制区域320，其中，纤维坯料200在通过压制但不固化区域192a时的压力与通过正常压制的固化区域192b时的 压力相等或低于通过正常压制的固化区域192b时的压力。
由于纤维坯料200由进料轮廓191进入正常压制的固化区域192b前，首先进入到一压制但不固化区域192a，这样纤维坯料200中的空气可以在压制但不固化区域192a内向两侧和进料轮廓方向排出，同时正常压制的固化区域192b中的纤维坯料在压制固化过程中产生的气体一方面从正常压制的固化区域192b的两侧排出，另一部分则可以向压制但不固化区域192a中排放，如图10所示，由于压制但不固化区域192a内的胶粘剂没有被固化，气体可以顺利的排出，最终使得压制后的纤维板材上、下表面的预固化层的厚度相对于现有技术至少可减少30％～40％，甚至只有现有技术的30％，如图11所示，从而较大幅度地节约了原材料，减少了砂光量和降低了砂光设备电耗和砂带消耗，降低了砂光产生的粉尘。
另外，由于纤维坯料200经过压制但不固化区域192a时的胶粘剂没有达到完全固化，纤维坯料200在正常压制的固化区域192b所释放的气体可以经由压制但不固化区域192a向进料轮廓191方向排出，而这部分气体不足以在上、下钢带130、140与待压制的纤维坯料200接触的位置产生旋涡气流，即使产生了旋涡气流，使得待压制的纤维坯料200的上、下表面产生了其胶粘剂并未固化的粉尘团10(如图6所示)，而这些粉尘团10被带入压制但不固化区域192a内，由于待压制的纤维坯料200的胶粘剂在压制但不固化区域192a内没有固化，这些粉尘团10可以融合在待压制的纤维坯料200的表面，从而避免了纤维板材的表面形成粉尘斑。
另外，还可以通过将压制机上部110的上加压装置111在靠近压料通道192的进口的位置即为图7中的I处位置提升一定的距离，使上进给热压板170与纤维坯料200的进入方向形成“S”型曲面，使得在压制时上进给热压板170与下进给热压板180之间在I处位置形成一排气缝隙194(参见图7)。那么待压制的纤维坯料200在压制但不固化区域192a内所产生的气体以及在正常压 制的固化区域192b所产生的且向压制但不固化区域192a排放的大量气体可以经由排气缝隙194向纤维坯料的两侧排出，有效地减少了向进料轮廓方向排出的气体的流量，避免形成漩涡气流，这样就可以适当地加快进料速度，提高产量。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
