Abstract

本发明涉及一种塑胶冷却辊，属于高分子材料制造技术领域。包括空心的辊；辊的两端分别设有进水口和出水口；辊内壁上均匀间隔铺设有冷凝管；冷凝管的两端分别与进水口和出水口连接。辊内壁上间隔均匀贴装有半导体制冷器；半导体制冷片外侧贴装有导热管，导热管从辊的一端延伸而出，其延伸端点处与一组散热片贴合。本发明提供的塑胶冷却辊，在辊内铺设了半导体制冷片，当循环水冷却不及时，即可启动半导体制冷片辅助。而且，半导体制冷片可叠加多层，制冷效果更好。通常多级制冷片结构可以达到80摄氏度以上的两级温差。可以急速制冷，足以应对任何突发情况。

Description

一种塑胶冷却辊
技术领域
本发明涉及一种塑胶冷却辊，属于高分子材料制造技术领域。
背景技术
现有的EVA胶膜制程中，压延薄膜或胶黏带涂布时，在成品成卷时为了减少热材料冷却时收缩引起的变形，在成卷前将材料通过冷却辊使其降温来达到减少材料的变形。
目前一般的方法是，使用循环水冷却，在辊内设冷却管，然后通入冷水。当连续工作时间过长，或环境温度较高时，这种冷却方式的效果就会明显变差。而且，这样的冷却方式也不具有任何调节的能力。
发明内容
本发明解决的技术问题是：提出一种可连续作业，并可对温度进行调节的冷却辊。
为了解决上述技术问题，本发明提出的技术方案是：一种塑胶冷却辊，包括空心的辊；所述辊的两端分别设有进水口和出水口；所述辊内壁上均匀间隔铺设有冷凝管；所述冷凝管的两端分别与所述进水口和出水口连接。所述辊内壁上间隔均匀贴装有半导体制冷器；所述半导体制冷器外侧贴装有导热管，所述导热管从所述辊的一端延伸而出，其延伸端点处与一组散热片贴合。
本发明进一步的完善是：所述半导体制冷器是一级、两级或三级半导体制冷片叠加结构。
本发明更进一步的完善在于：所述散热器上装有散热风扇。
本发明带来的有益效果是：本发明提供的塑胶冷却辊，在辊内铺设了半导体制冷片，当循环水冷却不及时，即可启动半导体制冷片辅助。而且，半导体制冷片可叠加多层，制冷效果更好。通常多级制冷片结构可以达到80摄氏度以上的两级温差。可以急速制冷，足以应对任何突发情况。
附图说明
下面结合附图对本发明的作进一步说明。
图1是本发明一个优选实施例的侧视结构示意图。
图中标号示意如下：1-辊，2-冷凝管，3-半导体制冷器，4-导热管。
具体实施方式
实施例
本实施例的一种塑胶冷却辊，包括空心的辊1；辊1的两端分别设有进水口和出水口；辊1内壁上均匀间隔铺设有冷凝管2；冷凝管2的两端分别与进水口和出水口连接。辊1内壁上间隔均匀贴装有半导体制冷器3；半导体制冷器3外侧贴装有导热管4，导热管4从辊1的一端延伸而出，其延伸端点处与一组散热片（图中未示）贴合。
本实施例中的半导体制冷器3是采用两级半导体制冷片叠加而成，其冷热两端温差在60摄氏度以上。如果需要更强的效果，也可实用三级本道题制冷片叠加，其温差可以达到80摄氏度以上。
同时，本实施例中的散热器上装有散热风扇，以将导热管4导出的热量及时散发。
工作时，冷凝管2内通入循环冷水，进行冷却。如果发现冷却不及，则马上启动半导体制冷器5，进行辅助制冷，直到循环冷水再次恢复到原始温度。
本发明不局限于上述实施例，凡采用等同替换形成的技术方案，均落在本发明要求的保护范围内。
