style="font-size:12px;font-family:simsun;">YP890</span>卷筒纸书刊胶印机由于生产原料（主要是纸张）、机器构造等多种原因，经常出现折页粘脏现象，而且始终未能根除。特别是一次在印刷时，粘脏现象尤为严重。笔者将此故障的排除经验介绍如下，供同行参考。 </span><span style="font-size:12px;font-family:simsun;"> 该书所用的是定量为<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="55" unitname="g"><span lang="EN-US"

target="_blank">吸墨性较差</a>，机器本身没有干燥系统，版式设计也有所欠缺。该书每一套版都有一个或两个<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="82" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">82mm</span></st1 :chmetcnv>×<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="211" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">211mm</span></st1 :chmetcnv>的出血题头，每面下页码处都有<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="65" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">65mm</span></st1 :chmetcnv>×<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False"

style="font-size:12px;font-family:simsun;">80%</span>的网纹块紧挨角线。也就是说折页时辗纸辊的压纸宽度只有<span lang="EN-US" style="font-size:12px;font-family:simsun;">7</span>～<span lang="EN-US" style="font-size:12px;font-family:simsun;">8mm</span>，天头处只有<span lang="EN-US" style="font-size:12px;font-family:simsun;">1</span>～<span lang="EN-US" style="font-size:12px;font-family:simsun;">2mm</span>宽。如果粘脏裁切不掉就会影响产品质量。 <span lang="EN-US"><o :p></o :p></span></span></p> <p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:28pt;mso-char-indent-count:2.0;"><span style="font-size:12px;font-family:simsun;">起初维修人员通过降低机速、调小墨量、调轻辗纸辊压力的方法调节，但试印后不可行，由于任务紧，无奈之下，只好边生产边调整。 <span lang="EN-US"><o :p></o :p></span></span></p> <p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:28pt;mso-char-indent-count:2.0;"><span style="font-size:12px;font-family:simsun;">首先从折页机辗纸辊调整开始，维修人员调小了辗纸辊的压纸量（紧靠裁切线），把辗纸辊调紧些，试印效果稍好些。但由于纸张性能不稳定，过接头时纸张两边松紧不一，生产中天头来回跑，纸张浪费很大。通过检查发现辗纸辊有磨损，更换新的橡胶辊，又在胶辊表面缠上一层不吸墨的透明胶带，压力再适当加大些。开机时基本能维持正常生产。 <span lang="EN-US"><o :p></o :p></span></span></p> <p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:28pt;mso-char-indent-count:2.0;"><span style="font-size:12px;font-family:simsun;">但在随后转印另一套版时，又出现了新的粘脏现象。正黑版有<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="82" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">82mm</span></st1 :chmetcnv>×<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="217" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">217mm</span></st1 :chmetcnv>的出血题头时，在<span lang="EN-US" style="font-size:12px;font-family:simsun;">16</span>开书背处粘脏严重，从叼口到拖梢有<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="10" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">10mm</span></st1 :chmetcnv>宽，必须停机排除。 <span lang="EN-US"><o :p></o :p></span></span></p> <p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:28pt;mso-char-indent-count:2.0;"><span style="font-size:12px;font-family:simsun;">通过观察发现是<span lang="EN-US" style="font-size:12px;font-family:simsun;">16</span>开压痕刀装置所致。调小压痕刀的压力，但纸带前后摆动仍有粘脏现象。为了根除该故障，卸掉压痕装置。虽然纸带上没了脏迹，但也没了压痕，在第二折时折标来回跑，因此还得装上压痕刀。在装卸时维修人员发现<a href="http://www.lzjpj.com/" target="_blank">压痕刀的刀垫</a>才是<a href="http://www.lzjpj.com/" target="_blank">故障的根源</a>，于是用<span lang="EN-US" style="font-size:12px;font-family:simsun;">6</span>个与刀垫等厚的螺母代替粘脏的刀垫，再用长<st1 :chmetcnv w:st="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="20" unitname="mm"><span lang="EN-US" style="font-size:12px;font-family:simsun;">20mm</span></st1 :chmetcnv>的螺丝将另一刀垫及压痕刀固定在托架上。试印，问题解决了。后来又加工了<span lang="EN-US" style="font-size:12px;font-family:simsun;">6</span>个与刀垫等厚的垫片代替螺母，换上后生产状况良好。<span lang="EN-US"><o :p></o :p></span></span></p> </td> </tr>
