Abstract

本发明公开了一种切纸机的改进发明,该机具有机体,所述机体具有送纸平台(2)、推纸装置、切纸刀(3)及运行推纸装置(1)和切纸刀工作的电控装置,所述推纸装置(1)具有齿状推板(4),所述齿状推板(4)具有推纸面(8)及底面,其特征在于所述齿状推板(4)底面与送纸平台(2)之间设有承磨块(6),使齿状推板(4)的底面与送纸平台(2)的平面之间保持间隙。本发明由于将以往的齿状推板底面与送纸平台的平面接触改为通过一个承磨块来接触,而齿状推板的底面则始终与送纸平台的平面保持间隙,而且在承磨块上设置了弹簧,该弹簧的弹力可以永远使承磨块的底面与送纸平台的平面接触,能自动调节。并且使送纸平台的平面受承磨块刮擦后不会留下刮痕,本发明与现有技术相比具有突出的实质性特点与显著的进步。

Description

切纸机
技术领域:
本发明所涉及的是一种印刷机械,具体涉及的是一种切纸机的送纸机构的改进发明,特别涉及的是一种切纸机推纸装置的改进发明。
背景技术:
在沿用切纸机送纸器上栅栏状齿板的前下端与工作平台的间隙根据国家标准要达到小于0.1毫米的要求,由于切纸机平台尺寸大、且厚度薄,致其刚性差容易变形,因此在送纸器左、中、右三块齿板上均采用弹簧保持与平台平面吻合,可以使被切的纸张不至于滞留在送纸平面上。由于推纸装置与送纸平台的材料相同,都属于金属材料,而推纸装置在送纸平台的平面上频繁移动,会破坏送纸平台平面的镀层与光洁度,还会留下刮痕,影响送纸质量。
发明内容:
鉴于公知技术存在的问题,本发明所解决的技术问题是为了提供一种结构简单,推纸装置在送纸平台的平面移动后不会破坏平面的镀层与光洁度的一种切纸机。为了解决上述技术问题,本发明是采用如下技术方案来实现的:该机具有机体,所述机体具有送纸平台、推纸装置、切纸刀及运行推纸装置和切纸刀工作的电控装置,所述推纸装置具有齿状推板,所述齿状推板具有推纸面及底面,其特征在于所述齿状推板底面与送纸平台之间设有承磨块,使齿状推板的底面与送纸平台的平面之间保持间隙。所述承磨块镶嵌在齿状推板前下端的齿上,所述承磨块的底面与送纸平台的平面接触,所述承磨块的顶部与齿状推板的齿之间具有弹簧,承磨块的推纸面与齿状推板的推纸面处于同一平面。所述承磨块为工程塑料。所述承磨块呈U形。本发明由于将以往的齿状推板底面与送纸平台的平面接触改为通过一个承磨块来接触,而齿状推板的底面则始终与送纸平台的平面保持间隙,并且该承磨块采用非金属材料,为工程塑料,因此摩擦系数小。而且在承磨块上设置了弹簧,该弹簧的弹力可以永远使承磨块的底面与送纸平台的平面接触,能自动调节。并且使送纸平台的平面受承磨块刮擦后不会留下刮痕。本发明与现有技术相比,具有突出的实质性特点与显著的进步。
附图说明:
本发明有如下附图;
图1为本发明的结构示意图;
图2为本发明承磨块结构局部剖视放大图;
图3为齿状推板安装上承磨块后的俯视图;
图4为承受磨块结构示意图。
具体实施方式:
附图表示了本发明的结构及其实施例,下面再结合附图进一步描述其实施例的有关细节及工作原理。该种切纸机,具有机体,所述机体具有送纸平台2、推纸装置1、切纸刀3及运行推纸装置1和切纸刀3工作的电控装置,所述推纸装置1具有齿状推板4,所述齿状推板4具有推纸面8及底面,所述齿状推板4与送纸平台2之间设有U形承磨块6,使齿状推板4的底面与送纸平台2的平面之间保持间隙,而承磨块6的底面则与送纸平台2的平面接触,承磨块6的形状也可以是U形以外的任何其他形状,该承磨块6的作用就是能够使最下面的,将要被裁切的纸张不至于滞留在送纸平台2的平面上,所述承磨块6镶嵌在齿状推板4前下端的齿上,所述承磨块6的顶部与齿状推板4的镶嵌部位的底部之间具有弹簧5,承磨块6的推纸面7与齿状推板4的推纸面处于同一平面。所述承磨块为工程塑料。本发明由于将以往的齿状推板底面与送纸平台的平面接触改为由一个承磨块与送纸平台的平面接触,这就可以使齿状推板的底面始终与送纸平台的平面保持间隙,避免了齿状推板刮擦送纸平台平面的现象。承磨块采用非金属材料,是一种工程塑料,由于工程塑料与金属材料的物理性能不同,不会像金属与金属硬碰硬的刮擦,因此,摩擦系数小。而且在承磨块上设置了小弹簧,该弹簧的弹力可以永远使承磨块的底面与送纸平台的平面接触,受力均匀,使送纸平台的平面受承磨块刮擦后不会留下刮痕。本发明与现有技术相比,具有突出的实质性特点与显著的进步。
