Description
技术领域
本发明整体涉及水下造粒系统,并特别涉及水下造粒刀具。
背景技术
在挤压聚合物的水下造粒领域,大家都知道聚合物或更普遍的热塑材料可以通过穿过压模板中的多孔眼挤压造粒,使熔化的聚合物以连续绳索的形状(面条形)浸入充填室的水中,在没入水中时立即被包括多个刀具的旋转切割组件切割成颗粒。这些刀具具有切割边缘,这些切割边缘形成直接与模压板的平面表面相邻并且平行的切割面。然后得到的小片或颗粒被带入到水流中。
特别是,在该造粒过程中,刀具经受许多决定整个过程的生产质量的约束。尤其是,为了达到准确的切割动作以及颗粒的均匀尺寸和形状,这些刀具必须具有耐腐蚀、耐空蚀、耐磨损及耐高温的硬质材料的锋利切割边缘。
因此,普通的刀具一般由以下部分组成:
-钢(或不锈钢)形成的主体,能够安装在切割转子上,并作为刀刃持有件;以及
-包括刀具切割边缘并由碳化钛(TiC)或碳化钨形成的刀刃,通过焊接或其它适当方式连接到刀刃持有件上,则与刀刃持有件形成单体零件。
因此这些刀刃一般构成目前提出的水下造粒刀具的整体部分。
但是,因为必须在水流和高温下以高处理速度依次并准确切割不同熔化指数的聚合物股,并且可以与压模板接触,刀刃的损坏比夹具的损坏大得多。尽管如此,由于刀刃和刀刃持有件形成单体件,迫使制造者定期更换整个刀具,尽管刀刃持有件仍可运行。
另外,水下造粒刀具不易触及。因此,除了刀具本身的成本外,用以允许更换刀具的系统停工期是非常昂贵的,因为更换刀具的操作通常是很耗时的。实际上,当需要更换刀具时,操作者应暂停造粒过程,打开造粒机,以便可以触及坏的刀具,拧开螺钉/从旋转切割组件取出坏刀具,放置/旋拧新的刀具,并调整该刀具使其适应模压板表面,然后进行造粒过程。因此,现有水下造粒切割部件不容易使用。
发明内容
各种实施例是针对上述问题中的一个或多个的作用。为了对不同实施例的某些方面提供基本的了解,下面对一些实施例进行简要的描述。这个简述不是对这些不同实施例的专门综述。它不是要鉴别这些实施例的关键零件,或确定这些实施例的范围。它的唯一目的是以简化的形式介绍一些概念,作为下面讨论的更多详细描述的序言。
不同实施例的目标是克服上述缺点。
不同实施例涉及用于挤压聚合物的水下造粒刀刃,该刀刃包括通过一轮廓限定的板片,该轮廓包括:
-具有第一端和第二端的切割边缘轮廓,以及
-连接切割边缘轮廓的第一端和第二端的外轮廓,该外轮廓至少包括第一支撑部分和第二支撑部分,该第一支撑部件和第二支撑部分远离切割边缘轮廓发散延伸,并用于被接纳在燕尾形的槽中。
根据更广的方面,板片是梯形的板片,该梯形的板片的短底边包括切割边缘轮廓。该板片是被截断的倾斜梯形金字塔形。
根据另一普遍方面,切割边缘轮廓是弯曲波浪形,或以预定曲线半径弯曲。
根据一普遍方面,刀刃由碳化钛或碳化钨形成。
另外,不同实施例涉及用于持有上述刀刃的刀刃持有件,刀刃持有件包括第一纵向锁定零件和第二锁定零件,第二锁定零件用于在该第一纵向锁定零件的纵向延伸中可拆卸地安装在第一纵向锁定零件上,该刀刃持有件还包括槽,所述槽纵向延伸在第一纵向锁定零件以及安装在第一纵向锁定零件上的第二锁定零件的侧表面上,使得槽的内轮廓至少包括在第一纵向锁定零件中的第一部分,和在第二锁定零件中的第二部分,因此形成燕尾形的槽。
根据一普遍方面,第二锁定零件用于通过榫头-榫杆连接件可拆卸地安装在第一纵向锁定零件上,以防止第一纵向锁定零件和第二锁定零件一个相对于另一个转动和引导它们的组装。
根据另一普遍方面,刀刃持有件还包括固定部件,用于把第二锁定零件可拆卸地安装在第一纵向锁定零件上。
另外,不同实施例涉及用于被挤压聚合物水下造粒的刀具,该刀具包括上述刀刃和上述刀刃持有件。
另外,不同实施例涉及用于被挤压聚合物水下造粒的水下造粒机的旋转刀具夹持器,该旋转刀具夹持器用于接纳上述刀具。
各实施例可以进行修改并具有替代形式,因此已经以图中例子的方式出示了一些特殊实施例。但是,应理解的是,这些特殊实施例的描述不是将不同实施例局限于上述特殊形式。
当然要感激的是在任何现有实施例的发展中,可以进行自定义抉择以达到发展者的特殊目的,如遵守有关系统和有关商业的约束。这种发展的努力可能是耗时的,但是,尽管如此,这种努力对本领域专业人士的常规理解会从中受益。
附图说明
从下面的描述和权利要求,不同实施例的目标、优点和其它特征将更加清楚。下面仅作为解释例子并参照附图给出一些参考实施例的非限定描述,图中:
-图1表示一模压板和旋转刀具组件的组成零件的分解透视图;
-图2表示图1组件组装图和组成零件和用内六角扳手组装在该组件上的刀具的放大分解图;
-图3表示图1组装零件在被挤压聚合物造粒时的横截面图;
-图4、5、6、7、8分别表示符合一实施例的被挤压聚合物水下造粒刀具的透视图、俯视图、正视图、沿图6标示的VII-VII轴的截面图、和沿图6标示的VIII-VIII轴的纵向截面图;
-图9表示符合一实施例的包括刀刃持有件和刀刃的刀具的分解透视图;
-图10、11、12分别表示符合一实施例的用于被挤压聚合物水下造粒的刀刃的透视图、正视图、和左视图。
要指出的是,相同的参考特征适用于整个附图描述中的相同部分。
具体实施方式
参照图1,多个刀具1适于被安装在旋转刀具夹持器2上。在一实施例中,通过多个螺钉3将这些刀具1旋拧在刀具夹持器2上。在一替代实施例中,刀具1与旋转刀具夹持器2联结成一体(例如是切割轮的一部分,或者焊接在切割轮上),而不是通过螺钉3、螺栓或任何等效方法被固定在夹持器2上。
如图2所示,当各种刀具1被安装并通过旋转刀具夹持器2带动转动时,它们的切割边缘形成与模压板4的平面表面相邻并平行的切割平面。如图3所示,穿过模压板4中的多个孔眼41的绳索状的被挤压聚合物5立即被刀具1的切割边缘切割成颗粒51。
现在参照图4-9,用于水下造粒机的刀具1包括刀刃持有件和刀刃6。刀刃持有件包括主体10和子体11。主体10和子体11最好由不锈钢形成。
子体11用于在主体10的纵向延伸中可拆卸地安装在主体10上。在一实施例中,子体11通过螺钉12可拆卸地安装在主体10上。更普遍的是,子体11可以通过螺钉、螺栓或任何等效附着部件可拆卸地附着在主体10上。
为了防止主体10和子体11一个相对于另一个转动和引导它们的组装,(非圆形的)榫眼-榫头接头件14用于该连接(见图9)。
现在参照图10-12,刀刃6具有板片的形状。刀刃6最好由碳化钛(TiC)或碳化钨形成。在一实施例中,如在图10中可清楚地看到的,刀刃6是似梯形的板片(圆形或没有角的梯形)。
该板片的形状可以是被截断的倾斜梯形金字塔(见图10和12)。该梯形的长底边用于被接纳于在组装好的主体10和子体11的侧表面上纵向延伸的槽13中。梯形的短底边包括切割边缘61。图10-12的刀刃6具有横向对称平面。
在刀刃持有件中产生的槽13是在组装好的主体10和子体11的侧向表面上的连续纵向凹沟,因此槽13的内轮廓至少包括在主体10中的第一部分和在子体11中的第二部分,因此形成燕尾型的槽13(见图9)。因此,燕尾型的凹沟(或槽)13构成适于容纳/接纳刀刃6的梯形长底边并与刀刃6的梯形长底边配合的梯形槽,因此形成燕尾形连接件。换句话说,包括主体10和子体11的刀刃持有件通过包括梯形燕尾形的槽13或更广泛地包括任何燕尾形凹沟13的燕尾形连接件保持刀刃6。在该燕尾形连接件中,燕尾形榫眼是槽13,并且燕尾形榫头是刀刃6的外轮廓的一部分。
燕尾形的槽13在主体10和子体11的适当深度中纵向延伸,使得,当刀刃6嵌入其中时,刀刃6的切割边缘对角线地突出到主体10和子体11之外(见图7)。
燕尾形的槽13在组装好的主体10和子体11上延伸,因此主体10和子体11一起分别构成用于保持/互锁刀刃6的第一纵向锁定零件10和第二锁定零件11。
于是,通过从主体10(或更普遍地第一纵向锁定零件10)拧松子体11和/或将子体11(或更普遍地第二锁紧零件11)拧紧在主体10上,刀刃6可以可拆卸地保持在燕尾形的槽13中。
更普遍的是,刀刃6可以具有与刀刃持有件中相应的燕尾形的槽13相配合的任何其它合适形状。实际上,参照图10和11,刀刃6可以是被一轮廓限定的任何板片60,该轮廓包括:
-具有第一端62和第二端63的切割边缘轮廓61,以及
-连接切割边缘61的第一端62与第二端63的外轮廓64,该外轮廓64至少包括第一支撑部分65和第二支撑部分66,第一支撑部分65和第二支撑部分66远离切割边缘轮廓61延伸发散。
在一实施例中,切割边缘轮廓61可以是直线形、弯曲波浪形、以预定曲线半径弯曲、或者用于有效切割被挤压材料的任何适当形状。
相应的刀刃持有件包括能够相配接纳/容纳第一支撑部分65(即燕尾形的榫头)和第二支撑部分66(即燕尾形的榫槽)的燕尾形的凹沟,因此可以通过形成的燕尾形连接件将刀刃6锁定在它的相应的刀刃持有件上。
由于形成燕尾形连接件,可以通过刀刃持有件持有刀刃,而没有任何直接在刀刃上操作的螺钉部件。
参照图2,为了更换刀刃6,将艾伦螺钉扳手7插在螺钉12顶部的相应孔眼中并旋转,使得第二锁定元件11(即子体11)从第一纵向锁定零件10(即主体10)松开,因此刀刃可以被移动和从燕尾形的槽13中脱出。可以将识别第二锁定零件11和第一纵向锁定零件10相关的标志印在锁定零件10和11上,以避免混淆安装在旋转刀具夹持器2上的不同刀具1的第二锁定零件11。
上述实施例具有以下优点:
-通过围绕板片形的刀刃6的大部分,燕尾形的槽13对刀刃提供更大的支撑和保护(与沿小区域被铜焊或电焊到主体上的刀刃相比);
-刀刃6容易拆卸,因此容易更换。实际上,如图2所示,如果刀刃6的锋利度变差,它可以很容易被更换,不需要从旋转刀具夹持器2取出主体10(取出、固定和调整刀刃持有件的主体10是很耗时的)。另外,螺钉12可随时触及(从旋转刀具夹持器2的侧边),因此调整或替换刀刃6可以迅速和容易地完成。
-在生产成本方面,刀刃持有件(即,主体10和子体11)的使用寿命延长,不再需要铜焊或电焊过程。
-刀刃可更换,因此减少水下造粒机的整体操作和维修成本。
特别是,子体11安装在主体10的纵向延伸中允许径向触及旋转刀具夹持器2。
实际上,为了更换刀刃6,可以从旋转切割组件的侧面随时触及螺钉12,不需要完全打开造粒室。因此,刀刃6的更换可以迅速并很容易地完成(即,造粒过程的停工期最短)。
有利地,从上述实施例得到刀具1的特殊结构设置,使得可以(相对于模压板4和旋转刀具夹持器2)放射状地触及刀刃6和刀刃被可拆卸地固定至刀刃持有件。实际上,当刀刃不好时,可以迅速并很容易地更换可拆卸固定的刀刃6。
有利地,刀具1组成零件的上述结构设置包括燕尾形连接件,用于可拆卸地保持/固定用于被挤压聚合物的水下造粒的刀刃6。
