Description
技术领域
[0001] 本实用新型涉及橡胶加工领域，特别是一种橡塑密炼机剪切型转子。
背景技术
[0002] 在橡胶工业中，密炼机主要有两个用途:一是在密炼机转子强剪切作用下，使得橡胶发生解聚降解反应，破坏橡胶分子的立体网状结构，实现对橡胶的塑炼；二是通过一对转子的相向回转以及转子的剪切挤压，使得胶料与各种助剂充分混合，实现对橡胶的混炼。同时，在塑炼和混炼过程中，对温度控制非常严格，转子温度过高或过低都不利于炼胶。因此，转子是密炼机中对橡胶进行剪切塑料和混炼的核心零部件，其结构设计直接影响着密炼机的工作性能、生产效率和所炼胶料的质量。现代常用的四棱剪切型转子在设置转子棱形状时，通常设置为一长三短，长棱设置在转子一端，工作过程中两个转子相向转动，转子的棱顶相互剪切，由于只有一个长棱设置在转子一端，在工作时，只有单个长棱能够完整的将转子一边胶料往另一边推移，不利于胶料在密炼室内充分运动。且常用的四棱转子通常采用中空冷却结构对转子进行冷却，转子温度控制能力差。
发明内容
[0003] 本实用新型专利的目的在于克服上述不足问题，提供一种全新的，应用于橡胶加工环节，对胶料剪切混炼、塑料效果更好的橡塑密炼机剪切型转子。
[0004] 本实用新型专利为解决上述的技术问题，所采用的方案是:
[0005] 一种橡塑密炼机剪切型转子，采用四棱转子结构，其特征在于:转子棱包括两条等长的长棱和两条等长的短棱，相邻两个棱为一长一短，两条短棱位于转子两端。
[0006] 进一步地,所述转子棱位于基圆外表面圆周上。
[0007] 进一步地，转子冷却水道采用单向强制冷却结构。
[0008] 进一步地，转子的每条棱在转子基圆上螺旋分布，两转子棱旋向为反向对称。
[0009] 进一步地，所述转子棱的螺旋角为40°〜45°。
[0010] 本实用新型的有益效果:
[0011] 一、采用四棱转子结构型式，应用于炼胶环节，对胶料剪切、捏炼力度大。根据上述剪切型转子结构，其内部冷却水道沿转子棱和基圆呈螺旋型单向分布，在转子一端通入冷却水，从另一端流出，避免了采用中空冷却时通入的冷却水在转子体内循环不畅的问题。采用此种单向强制冷却更易于控制转子炼胶温度，提高炼胶质量和工作效率。
[0012] 二、采用单向强制冷却控制转子炼胶温度，炼胶质量好，工作效率高。
[0013] 三、进一步地，所述转子棱的螺旋角为40°〜45°，胶料对金属的摩擦角为37°〜38°，在转子棱的作用下能更好的实现胶料运动。当胶料运动到转子两端时，在短棱的阻挡挤压作用下朝转子中部移动，而位于转子中部的胶料在转子长棱作用下，通过两转子间的强剪切作用在两转子间充分移动，从而更好地实现胶料的的塑炼和混炼。
附图说明
[0014] 图1:转子棱结构示意图。
[0015] 图2是图1的横截面图。
[0016] 图3:转子内部冷却水道结构示意图。
[0017] 图中部位及编号:转子基圆1、转子长棱2、转子短棱3、冷却水道4。
具体实施方式
[0018] 下面结合附图对本实用新型专利作进一步说明。
[0019] 如图所示，此橡塑密炼机剪切型转子包括一对转子，转子采用四棱结构型式，没个转子基圆I外表面圆周上，设置两条等长的长棱2和两条等长的短棱3，相邻两个棱为一长一短，两条短棱3位于转子两端。长棱2和短棱3沿转子基圆I上的螺旋角为40°〜45°，两转子棱的旋向为反向对称。转子内部冷却水道4如图3所示，沿转子基圆和棱呈单向螺旋型分布，转子冷却时采用单向强制冷却。
[0020] 综上所述，采用新型橡塑密炼机剪切型转子能有效提高胶料的塑料和混炼，且炼胶温度更易于控制，生产效率得到提高。
