一种复合型轨枕的连续生产方法及其设备
摘要：
本发明提供了一种复合型轨枕的连续生产方法，该方法包括以下四个工序：（1）展开，展开玻璃纤维织布后通过撑展机构；（2）浸透，将聚氨酯树脂均匀地喷洒于所述玻璃纤维织布的表面，然后经过对辊，形成平整的表面；（3）卷绕，所述玻璃纤维织布卷绕于轨枕内芯的外表面，剪断玻璃纤维织布后将其放置于模具内；（4）成型，对所述模具内的聚氨酯树脂进行熟化，熟化完成后，脱除模具，得到所述复合型轨枕。本发明还提供一种复合型轨枕的连续生产的设备。该方法生产的轨枕层间剪切力不容易被破坏，且该方法轨枕的外表层中的聚氨酯树脂分布均匀，该方法实现了连续化和自动化生产。
摘要（英）：

The invention provides a continuous production method for a composite type sleeper. The continuous production method comprises the following four procedures: (1) spreading: enabling spread glass fiber woven fabric to pass through a supporting-spreading mechanism; (2) soaking: uniformly spraying polyurethane resin on the surface of the glass fiber woven fabric, and then enabling the glass fiber woven fabric to pass through pair rolls, thus forming a flat surface; (3) winding: winding the glass fiber woven fabric on the outer surface of a sleeper inner core, shearing off the glass fiber woven fabric and placing the sheared glass fiber woven fabric in a mold; and (4) molding: aging the polyurethane resin in the mold, removing the mold after the aging is ended, thus obtaining the composite type sleeper. The invention also provides continuous production equipment for the composite type sleeper. The interlayer shearing force of the sleeper produced by the method is cannot be damaged easily, the polyurethane resin in the outer surface of the sleeper produced by the method is distributed uniformly, and continuous and automatic production is realized by virtue of the method.
