接下来我给大家简要的
Next I’ll give a brief

介绍一下卷纸机
introduction to the rewinder

卷纸机位于造纸机的末端
The rewinder is located at the end of the paper machinery

用来把纸幅卷成纸卷
which is used to roll the paper into a paper reel

卷纸机的性能好坏
Whether the performance of the rewinder is good or bad

直接影响纸的卷取紧度和质量
can directly affect the paper rewinding tension and

以及造纸机的生产效率
quality and the production efficiency of the paper machinery

并影响纸的贮存
and affect the paper storage

和后续的加工性能
and subsequent processing performance

卷纸机按照卷取原理分为
The rewinder is divided into two types

轴式卷纸机
of axial rewinder and cylinder type

及圆筒式卷纸机两大类
rewinder according to the principle of rewinding

大多数纸机上采用圆筒式卷纸机
Most of the paper-making machine adopts the cylinder type rewinder

它操作方便
which is easy to operate

能卷取较大直径的纸卷
and can take up the paper of larger diameter

轴式卷纸机可借改变纸幅张力
The axial rewinder can adjust the paper rewinding tension

来调整纸卷的卷取紧度
by changing the tension of paper web

卷纸质量的要求是
the requirement for the quality of paper rewinding

纸卷达到均匀的紧度
is that the paper scroll reaches even tightness

太松的纸卷在保存的时候
too loose paper scroll is easy to deform in storage

容易变形、容易在卷轴上产生位移
easy to displace on the scroll

在复卷机上复卷该种纸卷时
When rewinding this kind of paper scroll on rewinding machine

由于回转不均匀有震动
due to the vibration caused by uneven rotation

纸幅所受拉力不一致
the pull force beard by paper web is inconsistent

从而增加纸幅断头的机会
so as to increase the opportunity of break

如纸卷卷得过紧
If the paper scroll is too tight

容易在纸幅中产生很大的应力
it is easy to produce very big stress in the paper web

退纸时会使纸幅弹性变形小
and make the elastic deformation of the paper web small

也会增加断头机会
and also increase the opportunity of break when unwinding

轴式卷纸机中
In shaft-type rewinder

纸幅卷套装在卷芯
the paper web scroll sleeve is arranged on the

或是特定的卷纸轴上
roll core or a specific reel shaft

由传动装置带动旋转缠绕成卷
which is rotated and wound by the drive

为了连续地卷纸
In order to roll the paper continuously

至少应有两套卷芯轴
there shall be at least two sets

以备交替缠卷
of roll core shafts for a lternate winding

图中所示的是
The structure schematic diagram of

轴式卷纸机结构示意图
shaft-type paper rewinder is shown in the picture

早先的轴式卷纸机是采用
The earlier shaft-type paper winder

机械式的摩擦离合器
used mechanical friction clutch

目前较新式的轴式纸卷纸机
At present, the newer shaft-type paper winder

采用电机和自控系统
uses motor and automatic control system

圆筒式卷纸机
Cylinder type paper rewinder belongs to

属于表面卷取的方式
the way of surface rewinding

缠绕的纸卷被压靠在
The rewound paper reel is pressed

被驱动的卷纸缸上
on the driven cylinder

借助摩擦力带动来卷纸
and rewind paper driven by friction

卷纸缸面的线速稳定
and the line speed of the cylinder surface of rewinding is stable

使纸卷具有均匀的卷取紧度
which makes the paper reel have a uniform rewinding tightness

传统的圆筒式卷纸机
The traditional structure of the cylinder type rewinder

结构如图所示
is shown in the picture

圆筒卷纸机分为
The cylinder type rewinder is divided into

摆臂式、导轨式圆筒卷纸机
the swing arm type, the guide rail type cylinder type rewinder

及改进的导轨式圆筒卷纸机
and the improved guide rail type cylinder type rewinder

圆筒卷纸机主要由叉臂传动
The cylinder type rewinder is mainly composed of the fork arm drive

也称为初卷臂传动
which also called the first rewinding arm drive

叉臂装置、卷纸缸
the fork arm device, the rewinding cylinder

加压装置、卷纸辊
the compression device, the rewinding roll

机架、助动装置
frame, mobility aids

卷纸辊架、辊子转移装置
rewinding roll frame, roll transfer device

及压缩空气系统等组成
and air compression system, etc.
