Description
技术领域
本发明涉及一种EVA牵引冷却定型机，属于塑料的加工的塑性状态物质的一般成型技术领域。
背景技术
目前，太阳能电池的封装一般采用乙烯一醋酸乙烯醋共聚物(EVA)胶膜将太阳能电池片包封，并与上下层保护材料粘合在一起，构成太阳能电池组件。EVA是一种典型的无规高分子化合物，它在加热熔融时具有良好的浸润性，冷却固化时具有良好的挠曲性、抗应力开裂性和粘结性能，是一种较为理想的能用于太阳能电池封装的材料。
EVA成膜采用的生产冷却过程是:从挤出机模头挤出的EVA膜温度高，它需要经过多组传送辊进行较长距离的传送，在传送过程中使EVA膜得以冷却和定型。
申请人发现，采用自然冷却，有以下缺点：
1.EVA膜的冷却速度较慢，用于冷却而设置的多组传送辊结构复
杂；
2.EVA冷却过程中生大量的废气，既不利于环保，又污染工作环
境。
发明内容
本发明要解决的技术问题是，针对现有技术不足，提出一种冷却速度快的具有附加制冷功能的EVA牵引冷却定型机。
本发明为解决上述技术问题提出的技术方案是：一种具有附加制冷功能的EVA牵引冷却定型机，包括设于底座上的前送料辊和后送料辊，所述前送料辊和后送料辊之间设有传送带，所述前送料辊和后送料辊之间设有制冷腔室，所述制冷腔室开有前开口和后开口，所述传送带依次通过制冷腔室前开口和后开口，所述制冷腔室的周圈侧壁设有冷却管，所述冷却管的进口设于相邻前送料辊的制冷腔室处，所述冷却管的出口设于相邻后送料辊的制冷腔室处，所述冷却管内固定有螺旋叶片，所述螺旋叶片的螺旋升角为21°～25°。
本发明采用上述技术方案的有益效果是：通过在前送料辊和后送料辊之间设有制冷腔室，制冷腔室开有前开口和后开口，传送带依次通过制冷腔室前开口和后开口，制冷腔室的周圈侧壁设有冷却管，冷却管的进口设于相邻前送料辊的制冷腔室处，冷却管的出口设于相邻后送料辊的制冷腔室处，冷却管内固定有螺旋叶片，螺旋叶片的螺旋升角为21°～25°；这样，从挤出机模头挤出的EVA膜，由传送带带动通过制冷腔室，制冷腔室内的温度通过冷却管进行降温，EVA膜可以得到快速的冷却，相比自然冷却，具有冷却速度快，设备占用空间小的优点。
上述技术方案的改进是：所述制冷腔室相邻后送料辊的一端连接有抽气扇。
本发明采用上述技术方案的有益效果是：通过制冷腔室将EVA膜生产中的产生的废气收集，通过抽气扇将EVA膜生产中的产生的废气排出，保护了工作环境。
上述技术方案的改进是：所述螺旋叶片的螺旋升角为22°。
上述技术方案的改进是：所述冷却管埋设在制冷腔室侧壁内。
附图说明
下面结合附图对本发明作进一步说明：
图1是本发明实施例具有附加制冷功能的EVA牵引冷却定型机的结构示意图。
具体实施方式
实施例
