Description

出粉刀 技术领域
本发明涉及激光打印技术领域，具体地说是一种安装于激光打印机碳粉盒中的出粉刀。本申请要求于2010年06月30日提交中国专利局、申请号为201020243823.4、名称为“一种出粉刀”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
背景技术
激光打印机是目前应用最广泛的计算机外部输出设备之一，它利用光、电、热的物理、化学原理通过相互作用输出文字或图像。基本过程可分为充电、曝光、显影、转印、定影、清洁、消电等七个步骤。首先，感光鼓表面由充电辊均匀地充电。激光扫描器向感光鼓发射含有图像信息的经过调制的激光，在感光鼓表面形成与待复制图像对应的静电潜像。接着，来自显影辊的碳粉转而吸附在感光鼓表面上使静电潜像转换成可视图像。随着感光鼓的旋转，由碳粉在感光鼓表面形成的可视图像换位至转印辊。经转印辊转印电压的作用，将可视图像转印至纸张等记录介质上，随后经加热辊和加压辊对记录介质上的可视图像进行加热加压后，将碳粉形成的可视图像完全固化于记录介质上。这样一个基本的成像动作就完成了。
在上述打印过程中，要将感光鼓上的静电潜像转换成可视图像，必须依赖于显影辊所吸附的碳粉。这些碳粉储存于碳粉仓中，并通过送粉辊实现向显影辊的输运供给。显影辊通过静电吸附效用将碳粉吸附在其表面，当通过与显影辊保持弹性接触的出粉刀的时候，显影辊表面的碳粉被均匀地刮平至适宜的厚度。由此可见，利用出粉刀控制并使显影辊表面具有一层均匀和厚度适宜的碳粉层是打印品质优良的关键。
参见图1a至图1d，现有一种出粉刀,包括支架1’以及固定于支架1’的金属质地的弹性刀片2’,该刀片2’采用敷膜工艺制作而成，即，在刀片2’与显影辊3’相接触的正面敷上一层耐磨且绝缘的高分子材料的薄膜层4’，从而达到提高出粉刀的耐磨性以及使碳粉摩擦带电更充分的目的。在垂直于显影辊轴线的截面上，可以看到只在刀片2’靠近显影辊3’一侧设有薄膜层4’，由于显影辊3’和出粉刀相接触的部位是在刀片2’悬臂的端部，这样就使得在显影辊3’连续高速旋转的时候敷在刀片2’表面的薄膜层4’的边缘很容易因摩擦而破损或脱离刀片2’。造成显影辊3’上粉不均匀，打印出来的稿面上出现竖向的线条，影响打印品质。
技术问题
本发明的目的在于提供一种出粉刀，以解决现有的带薄膜层的出粉刀在与显影辊相接触时其薄膜容易破损的问题。
 技术解决方案
为实现上述目的，本发明提供了一种出粉刀，包括弹性刀片，该刀片具有用于将其固定的固定部分和从该固定部分伸出的悬臂部分，该悬臂部分的外端具有用于与显影辊接触的接触部分，所述接触部分具有工作时面向所述显影辊的正面、工作时与所述显影辊相背的背面以及连接所述正面与背面的端面，所述正面上附着有可与所述显影辊接触的薄膜层，其中，所述薄膜层同时还附着在所述端面上。
优选地，所述薄膜层同时还附着在所述背面上，从而进一步增强了薄膜层的附着力。所述薄膜层附着在所述正面上的第一部分的宽度与附着在所述背面上的第二部分的宽度可以是相等的，也可以是不相等的。所述第一部分和第二部分的宽度可以为2mm~20mm。所述薄膜层附着在所述正面上的第一部分的长度与附着在所述背面上的第二部分的长度可以是相等的。
所述薄膜层可以为敷膜层、浸泡涂层或喷涂涂层。
所述刀片最好为平面形片体。
所述薄膜层的厚度可以为0.02mm~1mm，更好地是为0.02mm~0.1mm。
所述刀片为金属薄片或非金属薄片，所述金属薄片为铜片或不锈钢片。
所述出粉刀还包括与所述固定部分连接的刀片支架，该刀片支架与所述固定部分的连接形式为焊接、螺钉连接或粘胶连接。
 有益效果
本发明的出粉刀在其刀片与显影辊接触的接触部分的表面设置有薄膜层，该薄膜层同时附着在该接触部分的正面和端面上，使得薄膜层的外边缘远离了该薄膜层与显影辊相接触的工作区域，这种包裹起来的结构也增强了薄膜层的附着力，避免了现有的带薄膜层的出粉刀在打印一段时间后末端容易破损和翘起的缺陷。
