Description

橡胶衬里传送带装置
本发明涉及织物强化传送带装置，特别是坚固的织物传送带装置，其中强化织物带芯由单一的较厚的整体织物层做成，不同于多层结构传送带装置，多层结构是用多层较薄的织物做成，织物上覆盖聚氯乙烯(PVC)或橡胶。
加工密集织物传送带装置有大量的工艺问题，特别是在厚织物带芯中满意地注入聚氯乙烯。尽管如此，密集织物结构一般地是最优的，因为织物衬底由聚氯乙烯(PVC)填料变成整体的，从而避免了聚氯乙烯覆盖层的脱落问题，在多层传送带装置中这是经常发生过早损坏的原因。密集织物结构同样改进了支撑和抗裂性能。
到目前为止，密集织物结构局限于使用聚氯乙烯(PVC)作为浸渍剂。然而，在某种情况下使用橡胶外部覆盖层是有好处的，例如，在急降坡面上，众所周知，为了提供一种橡胶承载面采用了聚丁二烯—丙烯腈共聚物(腈橡胶)的外部覆盖层，它是和聚氯乙烯(PVC)兼容的，能在压力下融合在密集织物带芯的聚氯乙烯(PVC)表面上。该工艺过程，尽管能生产出一种满意的产品，但是比较昂贵，在某些情况下，在经济上是不可行的。
本发明的目标是提供一种密集织物传送带装置，外部具有橡胶覆盖层。并且，在最初加工聚氯乙烯(PVC)/织物衬底时成本不高。
过去试图生产一种全橡胶密集织物传送带装置未获成功，原因是很难将橡胶浆注入厚织物带芯内，并且，采用化学粘结系统在技术上未被证明是行得通的。它通常是用于薄的织物层，该种织物层是在加工多层传送带装置时采用的。采用化学粘结系统和密集织物带芯时，浸渍剂高聚物很难注满织品的空隙，这将会聚低织物带芯的机械性能。
上述问题现已在强化织物传送带装置的结构中获得解决。它是依靠本发明第一方面的密集织物带芯解决的。其提供了一种密集织物带芯，在织物带芯内注入橡胶，表面覆盖橡胶，其中经线由双股聚酯纤维线做成。该聚酯线为膨松结构，由叫做空气喷射卷曲的工艺过程用空气控制膨胀实现。
线的这种组合能提供最佳的拉伸平衡。纤维线以及卷曲结构线和橡胶的机械粘结力实现了这种拉伸平衡。
聚酯纤维线由连续伸长的纤维做成，它由平行的或没有缠绕的纤维组合而成。卷曲聚酯线由聚酯纤维做成，并且进一步加工成具有类似于切段短纤维线的外表和特性，关于这方面，聚酯纤维线是通过喷嘴输送的，在喷嘴内它受到高压空气流。线离开喷嘴后投射到撞击体上。在该过程中，使构成线的单股纤维形成环线。它们在由喷嘴投射到撞击体上的空气涡流的影响下部分地相互结合。一部分环线仍在线中，从而增加容积。而伸出外表面的某些环线使线产生卷曲结构。
比较聚酯纤维线和卷曲结构聚酯线的典型试验结果如下：
                              非卷曲结构  卷曲结构
抗断强度gms/denier(登尼尔)     8.3        4.2
拉断延伸率    10.94％    12.02％
最好是编织成简单的两层或三层结构的织物带芯，其中全部经线具有同样线路，采用这种结构，一米宽传送带的强度可达到1250KNs，生产更高强度的传送带装置，需要增加经线的数量。但是，由于织物密度大会影响浸渍剂注入到传送带的中间部分。
依靠本发明的第二方面可以解决这个问题。其是通过改变织物结构，在织物带芯的表面建立一个“空穴”，它会为浸渍剂注入传送带装置的中间部分提供方便，这个问题已经由采用一种编织方式解决了，其中内部经线与最外的两层线相比是沿直线绕成。内部经线最好是和每个第4根纬线交织。
由于内部经线和外部经线的线路不一样，需要对他们的拉伸特性进行平衡。否则，由于外部经线编织线路较短，将会受到不成比例的拉力，在内部经线受到全部拉伸之前，外部经线将会被拉断。
在本发明的最佳实施例中，由于内层经线采用了聚酯，外层经线采用了聚酰胺，如尼龙6，两者的拉伸特性得到了平衡，聚酯的拉断延伸率为14％，而尼龙6为19.5％，拉断延伸率5.5％的差别(典型的为6％)补偿了内部经线线路的不同，从而充分利用了内外经线的拉力潜能。
内部经线最好与卷曲聚酯线一起做成双股的，而外部经线与卷曲聚酯线一起有选择地做成双股的。
本发明的具体装置参考示图举例说明如下：
图1为简易双层结构密集织物带芯的示意图。经线由聚酯纤维线和聚酯卷曲线根据本发明的第一方面组合在一起。
图2为卷曲聚酯纤维线加工装置的简图。
图3为根据本发明的第二方面绘出的4层结构密集织物带芯的示意图。
图1中示出了用于制造传送带或传送带装置的两层(股)结构密集织物带芯。经线10由聚酯纤维线和卷曲聚酯线组合而成。
使用中加工传送带或传送带装置时，密集织物带芯在送入压制机以前浸入橡胶浆中，在压制机中预制的未固化的橡胶片贴在织物带芯的每一个表面上，在加热和加压的条件下进行固化。橡胶片可以是天然的，也可以是人造的。
卷曲聚酯线能保证橡胶片在织物带芯上的机械粘结力。
图2示出了卷曲聚酯纤维线加工装置的简图，加工装置由浸湿机构1、卷曲喷嘴2、和撞击体3组成，待卷曲的线通过浸湿机构1被送入喷嘴2，在其中受到喷嘴2侧孔4进来的压缩空气流的冲击。离开喷嘴后，投射到撞击体3上，在该过程中线的纤维分散，聚束，形成环线。
图3为4层结构的密集织物带芯，织物带芯的外表面有“空穴”。便于液体橡胶流入传送带的中间部位，编号为12的线具有较短的编织线路，由聚酰胺纤维做成，编号为13的线由聚酯纤维做成，线12和13可以有选择地和卷曲聚酯线绕在一起。
