Description

一种密炼机的剪啮一体转子
技术领域
本发明属于密炼机技术领域，涉及一种密炼机上使用的剪啮一体转子。
背景技术
转子是密炼机的核心部件，转子的结构直接影响密炼机炼胶质量和炼胶效率。目前的转子型式分为切线型和啮合型两大类。通过在使用当中对比，啮合型转子的炼胶质量要远远好于切线型转子，但效率却低于切线型转子；所以行业里把啮合型转子称为质量型转子，切线型转子称为产量型转子。因此，研究一种能够具有切线型转子的强剪切效果而提高效率、同时又能兼顾啮合型转子的高品质炼胶效果的新型转子尤为重要，是行业发展的需要。
发明内容
本发明的目的是提供一种密炼机的剪啮一体转子，该转子是一种剪啮共混转子，转子上有三条转子棱，三条转子棱的分布与布置、螺旋角等参数均与目前的啮合型转子一致，但每一条转子棱的棱宽都有宽棱宽和窄棱宽两部分。本发明所述的剪啮一体转子在工作状态时，保留了两个转子之间棱的相互啮合作用；同时，由于窄棱峰的存在，还达到了转子的剪切效果，增强了转子的炼胶效果。因此，既保证了较高的炼胶品质，又相对提高了炼胶效率。
为实现上述目的，本发明所采用的技术方案是：
一种密炼机的剪啮一体转子，所述剪啮一体转子上设有三条转子棱，分别为转子棱A1、转子棱B2和转子棱C3。
每一条转子棱的棱宽均分为宽棱宽和窄棱宽两部分，沿螺旋方向，每条转子棱长的1/2段为啮合型转子的宽棱宽，剩余1/2段为切线型转子的窄棱宽；宽棱宽与窄棱宽之间以渐变的方式过渡为一体。所述宽棱宽的截面与啮合型转子的截面相同，窄棱宽的截面与切线型转子的截面相同；且三条转子棱的宽棱宽的轴向截面相同、窄棱宽的轴向截面也相同；
其中，转子棱A1、转子棱B2的螺旋角a1的大小和方向均相同，转子棱A1与转子棱B2的相位相差180°；转子棱C3与转子棱B2的相位相差90°，且转子棱C3的螺旋角a2大于转子棱A1和转子棱B2的螺旋角a1，螺旋角a2与a1的螺旋方向相反。三条转子棱的轴向投影长度的关系为L1＞L2＞L3，其中，L1为转子棱A1的轴向投影长度，L2为转子棱B2的轴向投影长度，L3为转子棱C3的轴向投影长度。三条转子棱均具备剪切作用和啮合作用，能够提高炼胶效率和加强剪切功效。
本发明的有益效果：本发明所述的剪啮一体转子与传统的转子结构相比，转子棱同时具有啮合型转子棱的特性和切线型转子棱的特性，能够将啮合型转子和切线型转子的特点结合在一起，既能提高炼胶效率，又能提高炼胶质量。
