Description
本发明涉及一种用于激光打印机的处理盒压纸机构以及具有这种压纸机构的感光鼓组件及处理盒。本发明基于申请日为2010年02月25日、申请号为201020118946.5的中国实用新型专利申请，该申请的内容作为与本发明密切相关的参考文献引入本文。
作为常见的打印设备，激光打印机为现代化办公提供极大的方便。激光打印机大多使用可拆卸地安装到激光打印机内的处理盒提供打印使用的碳粉，在打印过程中，处理盒装载的碳粉转印在作为打印介质的纸张上，形成所需的图案和文字。
现有一类处理盒如图1所示，处理盒由碳粉盒1与感光鼓组件2构成，碳粉盒1具有容纳碳粉的腔体11，并在腔体内设有显影辊等部件。碳粉盒1可拆卸地安装在感光鼓组件2内，并与感光鼓组件2一起组成一个处理盒。
感光鼓组件2具有由一个上框架21以及一个下框架23构成的框架，上框架21安装在下框架23的上方，在上框架21与下框架22之间安装有感光鼓22。并且，碳粉盒1可拆卸地安装在下框架23的开口内。
参见图2，为说明问题清楚起见，图2中简化了激光打印机内的相关构件且略去了无关构件。处理盒安装到激光打印机后，感光鼓组件2与激光打印机的送纸系统配合。在下框架23的下端设有压纸机构，压纸机构由压纸辊24以及压纸辊定位块27构成，压纸辊定位块27用于将压纸辊24固定在下框架23的下端。
激光打印机内的送纸系统包括三个压块31以及两个送纸轮32，每一送纸轮32位于相邻的两个压块31之间，送纸轮32可沿其轴线旋转。压纸机构与送纸系统的具体机构如图3所示，在最左端的压块31的左端及最右端压块31的右端分别设有一根压簧33，用于将压纸辊定位块27以卡住的方式固定。
参见图3与图4，压纸辊24具有辊体25，辊体25的横截面为圆缺形，即辊体25的上端为平面，平面下方为圆弧面。辊体25的两端外设有自辊体25端面向外延伸的轴端26，轴端26的横截面积小于辊体25的横截面积。
压纸辊定位块27包括一个呈圆环柱状的套筒28以及位于套筒28上方的卡接部29，套筒28中部设有一个通孔，压纸辊24的轴端26可插入通孔内，以此实现压纸辊24的固定。卡接部29卡接在下框架23的下端，以将压纸辊24定位在下框架23上。
处理盒安装到激光打印机后，压簧33压在压纸辊定位块27的套筒28外端，从而使压纸辊24的辊体25与送纸轮32接触，纸张将从辊体25与送纸轮32之间穿过。由于送纸轮32不断地旋转，从而带动纸张进入处理盒。
但是，由于压纸辊24的辊体25的横截面并非圆形，不能随送纸轮32旋转而旋转，并且，在压簧33压下压纸辊定位块27后，辊体25与送纸轮32之间产生滑动摩擦，往往由于摩擦力过大而导致送纸轮33磨损，影响激光打印机的使用寿命。并且，送纸轮33与辊体25之间的摩擦还会造成激光打印机工作过程中产生较大的噪音，不利于激光打印机的正常工作。
本发明的主要目的是提供一种不易使送纸轮不当磨损的压纸机构；
本发明的另一目的是提供一种避免对激光打印机使用寿命造成影响的感光鼓组件；
本发明的再一目的是提供一种使激光打印机产生噪声较小的处理盒。
为实现上述的主要目的，本发明提供的压纸机构包括压纸辊及一对压纸辊定位块，压纸辊具有辊体以及自辊体两端面向外延伸的端轴，每一端轴的横截面积小于辊体的横截面积，压纸辊定位块具有一套筒以及自套筒向上延伸的卡接部，套筒具有一个通孔，压纸辊定位块通过通孔套装在端轴上，其中，端轴的外端延伸至套筒外，且在垂直于卡接部上表面的方向上，端轴的上端低于套筒的上端。
一个优选的方案是，端轴的上端为一平面，该平面与卡接部的上表面平行。这样，端轴上端的平面能防止端轴旋转，从而避免压纸辊旋转。并且，该平面与压簧之间的配合更为可靠，便于压簧将压纸辊固定。
为实现上述的另一目的，本发明提供的感光鼓组件包括框架及安装在框加上的感光鼓，框架的下方设有压纸机构，压纸机构具有压纸辊及一对压纸辊定位块，压纸辊具有辊体以及自辊体两端面向外延伸的端轴，每一端轴的横截面积小于辊体的横截面积，压纸辊定位块具有一套筒以及位于套筒上方的卡接部，套筒具有一个通孔，压纸辊定位块通过通孔套装在端轴上，其中，端轴的外端延伸至套筒外，且在垂直于卡接部上表面的方向上，端轴的上端低于套筒的上端。
由此可见，压纸辊的端轴伸出套筒外，压簧将压在端轴上，且端轴的上端低于套筒的上端，能减少压簧向压纸辊施加的压力，辊体与送纸轮之间的摩擦力也随之减少，激光打印机工作时产生的噪音也大大减少。
为实现上述的再一目的，本发明提供的处理盒包括感光鼓组件以及可拆卸地安装在感光鼓组件内的碳粉盒，感光鼓组件包括框架及安装在框架上的感光鼓，框架的下方设有压纸机构，该压纸机构具有压纸辊及一对压纸辊定位块，压纸辊具有辊体以及自辊体两端面向外延伸的端轴，每一端轴的横截面积小于辊体的横截面积，压纸辊定位块具有一套筒以及位于套筒上方的卡接部，套筒具有一个通孔，压纸辊定位块通过通孔套装在端轴上，其中，端轴的外端延伸至套筒外，且在垂直于卡接部上表面的方向上，端轴的上端低于套筒的上端。
由上述方案可见，处理盒装入激光打印机后，压簧将压在压纸辊的端轴上，压簧向压纸辊施加的压力较小，使压纸辊与送纸轮之间的压力减小，避免压纸辊磨损送纸轮，也减少激光打印机工作时产生的噪音。
图1是现有一种处理盒的结构分解图；
图2是现有感光鼓组件与激光打印机送纸系统配合的结构示意图；
图3是现有压纸机构与激光打印机送纸系统配合的结构示意图；
图4是现有压纸机构的剖视放大图；
图5是本发明压纸机构实施例与激光打印机送纸系统配合的示意图；
图6是本发明压纸机构实施例的局部放大图；
图7是本发明压纸机构实施例的剖视放大图。
以下结合附图及实施例对本发明作进一步说明。
根据本发明的处理盒由一个感光鼓组件以及一个碳粉盒构成，碳粉盒可拆卸地安装在感光鼓组件内，碳粉盒具有一个壳体，壳体围成容纳碳粉的腔体，碳粉盒还安装有显影辊等部件。感光鼓组件具有一个由上框架及一个下框架构成的框架，上框架安装在下框架的上方，且在上框架与下框架之间安装有一个感光鼓，这些与现有的处理盒相同。不同处是在感光鼓组件下框架的下端设有本发明提供的压纸机构。
参见图5，本实施例的压纸机构40由压纸辊41以及压纸辊定位块51组成，压纸机构40位于激光打印机送纸系统的上方。送纸系统具有三个压块31以及两个送纸轮32，每一送纸轮32位于相邻的两个压纸31之间。
在最左端压块31的左端以及最右端压块31的右端分别设有一根压簧33，压簧33压在压纸辊41的端部，从而将压纸辊41推向送纸轮32，以便纸张从压纸辊41与送纸轮32之间穿过。
参见图6，压纸辊41具有辊体42以及自辊体42两个端面向外延伸的端轴45，端轴45的横截面积小于辊体42的横截面积。
压纸辊定位块51具有一个套筒52，套筒52的中部为一个通孔53，通孔53的上端面为一个平面，通孔53的横截面形状与端轴45的横截面形状相同，优选地，通孔53与端轴45过盈配合。
套筒52的上方设有一个卡接部55，卡接部55的两个侧壁分别设有一个凸块57，用于卡接在下框架的下端，以将压纸辊41定位在下框架上。
辊体42的上端为一个平面43，平面43与卡接部55的上表面56平行。端轴45的上端也是一个平面46，如图7所示的，辊体42的平面43与端轴45的平面46共面设置。优选地，压纸辊41的辊体42与端轴45一体成型。
回看图6，端轴45的外端伸出套筒52外。在垂直于卡接部55上表面56的方向上，即图6中Z轴方向上，端轴45的平面46低于套筒52的上端。这样，如图5所示，处理盒装入激光打印机后，压簧33压在端轴45露在套筒52之外的部分，由于端轴45的外露部分的上端低于套筒52的上端，压簧33向端轴45施加的压力较小，则辊体42向送纸轮32施加的压力也较小，能有效避免压纸辊41磨损送纸轮32，延长激光打印机的使用寿命。并且，由于辊体42与送纸轮32之间的摩擦力减小，激光打印机工作时产生的噪音也减小。
当然，上述实施例仅是本发明优选的实施方案，实际应用时，还可以有更多的改变，例如，压纸辊端轴的上表面设计成圆弧面而并非平面；或者，端轴与套筒的通孔之间间隙配合而并非过盈配合等，这些改变并不影响本发明的实施。
最后需要强调的是，本发明不限于上述实施方式，如卡接部形状的改变、压纸辊辊体横截面形状的改变等变化也应该包括在本发明权利要求的保护范围内。
本发明提供的压纸机构由于端轴延伸到套筒外，处理盒装入激光打印机后，压簧将压在伸出套筒外的端轴上，并且压纸辊的端轴上端低于套筒的上端，压簧压在端轴上时压簧向端轴施加的压力较原来的小，减小辊体向送纸轮施加的压力，辊体与送纸轮之间的摩擦力变小，避免送纸轮磨损。
