Description

新型半连续高速纺丝机
技术领域
本发明涉及一种纺丝设备， 具体地说， 本发明涉及一种半连续高速纺丝机。 背景技术
由纤维素原料提取出纯净的甲纤维素， 称为浆粕。 用烧碱、 二硫化碳处理， 得到橙黄色的纤维素黄原酸钠说，再溶解在稀氢氧化钠溶液中， 成为粘稠的纺丝原 液， 称为粘胶。 粘胶经过滤、 熟成、 脱泡后， 进行湿法纺丝， 凝固浴由硫酸、 硫 酸钠和硫酸锌组成。粘胶中的纤维素黄原酸钠与凝固浴中的硫酸作用而分解， 纤 维素再生而析出， 所得纤维素纤维经水洗、 脱硫、 漂白、 干燥后成为粘胶纤维。 粘胶长丝即粘胶纤维的一种， 也是由上述工艺制书得。
在纺丝及纺丝后处理过程中， 纺丝机的选择有半连续纺织机和连续纺织机， 从工艺和设备两方面来说， 这两种纺丝机存在以下区别：
1、 从生产工艺的角度来说， 半连续纺丝机是将纺丝和后处理 （后处理包括 洗涤、 烘干、 成筒等步骤） 分开， 单独完成， 半连续纺丝机主要负责纺丝部分； 而连续纺丝机是将纺丝和后处理（后处理包括洗涤、 烘干、 成筒等步骤）工序集 中在一起连续完成， 连续纺丝负责从纺丝到后处理的所有步骤。
2、 从设备结构的角度来说， 半连续纺丝机包括供胶机构、 喷丝机构、 丝条 成型机构、 纺丝辊机构、 清洗机构以及卷绕机构， 得到的产品为落入离心缸中的 丝饼； 而连续纺丝机具有供胶机构、 喷丝机构、 丝条成型机构、 纺丝辊机构、 清 洗机构， 没有卷绕机构， 丝条直接进入淋洗、 烘干等机构， 最后得到卷绕成型的 丝筒。
基于以上两种纺丝机的区别， 其各自的优缺点如下：
1、 半连续纺丝机 （如图 1-图 3所示）：
优点： 由于有单独进行的后处理步骤， 且后处理步骤中还有低温脱硫、 低温 长时间烘干的过程， 产品具有强度高、 白度高， 丝条柔软亮丽的特点；
缺点： 纺速低， 后处理费用高， 增加生产成本。
2、 连续纺丝机：
优点： 纺速高， 产量提高； 纺丝与后处理集中在一起进行， 生产成本降低； 缺点： 由于丝条是即洗即烘， 丝条强度低， 白度低， 丝条粗糙， 质量不如半 连续纺丝机的产品； 为增加丝条抱合上浆， 绣花线染色时浆料需去除， 增加下游 产品生产成本； 对原料 （粘胶） 质量要求高。
现有技术中最常见的半连续纺丝机为 R535半连续纺丝机 (如图 1-图 3所示， 包括机架 1、 供胶装置 2、 丝条成型装置 3、 纺丝装置 4和卷绕装置 5， 纺丝装置 4中纺丝辊相对于纺面 101的操作面 102为纵向设置）， 其纺丝的主要流程为： 粘胶通过滤器过滤后用喷丝头喷入酸浴槽内经过反应成型为丝条，丝条通过 牵伸盘牵伸至凝固辊，丝条在凝固辊上卷绕一定圈数的距离进行一段时间的反应 后再升头至捻面去酸辊， 去酸辊上方采用滴水淋洗的方式对丝条进行去酸洗涤， 丝条在去酸辊上卷绕一定圈数的距离再导入离心缸， 最后得到丝饼。
其中， 纺丝辊体主要分为去酸辊和凝固辊， 纺丝机的每个锭位分别使用一对 凝固辊和一对去酸辊， 凝固辊安装在纺面， 去酸辊安装在捻面， 相互背离， 辊体 的固定方式均为一端固定， 安装方向相对纺丝机纺面的操作面位置成纵向安装。 另现 R535三缸丝纺丝机的三圆筒排风采用三缸同风道排风方式。
现有 R535A半连续纺丝机其丝条成型部分及纺丝辊结构和安装方式无法进 行高速纺丝， 其纺丝纺速在 70-90m/min左右。 同时其设备结构及安装方式等造 成纺丝机设备占地面积大、 能耗高、 工艺流程复杂、 维护点多， 配件消耗大、 产 品成本高等缺点。 另 R535三缸丝的三圆筒三缸同风道排风方式在排风过程中相 互形成干扰， 造成排风效果差。
现有技术中最常见的连续纺丝机结构如图 4-图 6所示，其前半部分包括机架 1、供胶装置 2、丝条成型装置 3和纺丝装置 4， 纺丝装置 4中纺丝辊相对于纺面 101的操作面 102也为纵向设置。
国家知识产权局于 2000.12.6公开了一件公开号为 CN1356409, 名称为 "单 路多丝离心纺和半连续纺丝机及其粘胶纺丝工艺"的发明专利， 该发明公开了一 种离心式半连续纺丝机， 其包括粘胶输送系统、 摇摆管组件、 刮酸、 牵伸盘、 凝 固辊、 去酸辊、 升降架及漏斗、 离心缸及电锭系统， 粘胶输送系统由机头和机尾 两端同时进胶的多路粘胶管及其支撑机构组成；摇摆管组件由与多路胶管串接的 多路并联的计量泵、虑套、 曲管及喷头组成； 在双凝固辊的上方丝条行走路径上 设有上下安装的由两个去酸辊组成的去酸辊组件； 在机器升降架上，装置与丝条 数目相同的同步动作的漏斗； 其离心缸、 电锭系统设置成为每锭多离心缸及与其 配套的电锭和控制机构。
上述发明可同时生产多根丝， 大幅度提高了粘胶长丝的产量，但是该发明由 于其纺丝机的每个锭位分别使用一对凝固辊和一对去酸辊， 凝固辊安装在纺面， 去酸辊安装在捻面， 相互背离， 辊体的固定方式均为一端固定， 安装方向相对纺 丝机操作面位置成纵向安装。 上述结构带来的问题如下：
1、 上述结构限制了辊的长度， 粘胶长丝在辊上行走的时间短， 粘胶长丝成 形时间短，如果要提高纺速，必然会导致粘胶长丝反应时间不够而降低产品质量， 所以采用传统的半连续纺丝机效率降低；
2、 为了提高效率， 通常会同时加工多根丝条， 但是多根粘胶长丝缠绕在现 有的纺丝辊上时又容易绞丝， 造成粘胶长丝断裂， 影响粘胶长丝的产品质量；
3、 另外， 所述的纺丝辊的固定方式为一端固定， 这样的固定形式为悬臂式， 在纺丝辊转动时， 处于一种不稳定的状态， 容易发生故障；
4、 所有纺丝辊都为一端固定， 势必需要结构极其复杂的传动机构来带动纺 丝辊的转动， 这样也会导致故障率的上升， 而且在更换丝线品种， 改变转动速度 时， 需要停车， 再进行传动系统中齿轮的更换， 这样使得生产效率降低， 生产成 本增加。
国家知识产权局于 1998.9.23公开了一件公开号为 CN2292097, 名称为 "粘 胶长丝连续纺丝机"的发明专利， 该专利涉及一种粘胶长丝连续纺丝机， 能连续 完成纺丝、 水洗、 烘干、 上油、 卷绕等， 其纺速可达 120m/min， 本发明在纺丝 机机台前设置粘胶过滤装置， 利用纺丝机泵轴带动计量泵运转， 其结构简单， 清 洗维修方便， 有效地过滤了粘胶中的杂质； 纺丝浴盒中将喷丝头置于摆管端部， 保证了喷丝头与玻璃管的同心度， 能够避免产生毛丝， 操作灵活， 工效高； 玻璃 管出口处采用丝条双转向装置，减小了丝条与导丝轮之间的摩擦力，牵伸比分配 合理， 成丝质量高。
上述由于丝条是即洗即烘， 丝条强度低， 白度低， 丝条粗糙， 质量不如半连 续纺丝机的产品； 为增加丝条抱合上浆， 绣花线染色时浆料需去除， 增加下游产 品生产成本； 对原料（粘胶）质量要求高。 另外， 上述连续纺丝机的纺丝辊依然 是相对于工人操作区域纵向设置，所以其安装方式也是一端固定，还是存在第一 篇现有技术专利中的问题。
国家知识产权局于 2008.7.23公开了一件公开号为 CN201089811 ,名称为 "粘 胶人造丝深浴纺连续纺丝机 "，该专利公开了一种粘胶人造丝深浴纺连续纺丝机， 解决现有连续纺丝机丝条剩余脂化度高所带来的问题。本发明采用的方案是成型 管与纺丝小辊之间设置有酸浴槽，从成型管伸出的丝条落入装有酸液的酸浴槽内 浸浴后再行至纺丝小辊。本发明增加深浴纺， 加强丝条的反应程度， 降低剩余脂 化度， 保证人丝品质， 并适用于绣花线的生产。
该工艺属 "二次浴"工艺， 二次浴酸浓、 酸温比一次浴低， 故需要增加一套 独立酸浴系统， 增加酸站投入成本。 另外， 上述连续纺丝机的纺丝辊依然是相对 于工人操作区域纵向设置，所以其安装方式也是一端固定，还是存在第一篇现有 技术专利中的问题。
国家知识产权局于 2005.8.31公开了一件公开号为 CN2721660, 名称为 "适 用于粘胶长丝一锭位同时纺三丝的半连续离心纺丝机"的发明专利，本发明公开 了一种适用于在半连续离心纺丝机的一个锭位上同时纺出三根丝条的连续离心 纺丝机， 这种半连续离心纺丝机的每节内能够同时生产出 18个丝饼的纺丝机。 通过在半连续离心纺丝机的每节安装 18个电锭、 18个离心缸的部件， 能够在不 增加设备台数、 公用运行成本、 占地面积及投资的情况下， 节约纺丝机的维修时 间， 降低单个丝饼的生产成本， 提高纺丝机的利用率， 且设备维护和操作方便， 在系统设备改进后使其生产能力达到原设计能力从原来的每节 6个丝饼或 12个 丝饼达到 18个丝饼； 同时满足生产质量要求。
虽然单机每节的产量由于增加电锭、离心缸装置能够提高产量，但是该纺丝 机的纺速任然没有提高， 如果提高了纺速， 又会因为丝条反应不充分影响最终产 品的质量。另外， 上述半连续纺丝机的纺丝辊依然是相对于工人操作区域纵向设 置， 所以其安装方式也是一端固定， 还是存在第一篇现有技术专利中的问题。
又如申请号为 89217293.2， 申请日为 1989-09-23， 名称为 "粘胶丝管中成型 高速纺丝装置"， 其技术方案为： 本发明属于粘胶纤维高速纺丝装置，主要由输送 管、 喷丝头、成型管、浴槽组成。在凝固槽和回液槽间用一细直径的成型管连通, 与成型管配套的锥形喷头安装于成型管进口前面的相应位置，成型管出口附近为 一导丝器， 导丝器与纺丝漏斗之间仅设一个纺丝盘。上述发明采用的管中成型技 术应用于半连续离心式纺丝机， 虽然上述结构能够将纺速提高到每分钟 120米， 但是最终成型的丝条由于纺速过快会导致丝条反应时间不足，所以该专利仍然没 有解决由于纺速过快而带来的丝条反应不充分的问题。苏联制的连续纺丝机对于 纺丝辊部分进行了改进， 但是由于其生产得到的是丝束， 不能得到丝饼， 所以不 能直接应用在半连续纺丝机中。
综上所述， 现有的半连续纺丝机由于所有辊相对于纺丝机纺面均纵向安装， 存在纺速慢， 如果要提高纺速则无法保证丝条反应时间， 从而导致丝条质量不高 的问题； 传动结构采用齿轮传动， 传动结构复杂； 辊的一头没有固定在机架上， 在高速纺丝时， 辊就会发生晃动， 产生断丝、 废丝； 工人在日常操作时， 操作空 间小， 费时费力。
发明内容
本发明旨在解决现有采用半连续纺丝机， 特别是半连续纺丝机生产粘胶长 丝中，丝条反应不充分，导致无法提高纺速的问题，提供一种半连续高速纺丝机， 该半连续纺丝机在达到在提高纺速的同时，保证丝条反应充分，进而达到了保证 丝条质量， 提高生产效率、 降低纺丝成本的目的， 且结构简单、 断丝、 废丝少， 操作简单， 易于控制。
为了解决上述技术问题， 本发明采用的技术方案是：
新型半连续高速纺丝机， 包括机架和纺丝装置， 其特征在于： 所述纺丝装 置包括纺丝辊，所述纺丝辊至少为三根，所述纺丝辊相对于纺面的操作面均横向 设置， 所述纺丝辊相互平行。
所述的纺面的操作面是位于纺面区域内的水平工作面， 所述纺丝辊相对于 纺面的操作面横向设置是指当纺丝工人正对卷绕装置时，纺丝辊相对于纺丝工人 为横向安装。
所述纺丝辊有三根， 分别为牵伸辊、 凝固辊和去酸辊。
所述纺丝辊有四根， 分别为牵伸辊、 凝固辊、 去酸辊和导丝辊。
每根纺丝辊的两端分别固定在机架两侧的上方， 与驱动装置连接转动。 每根纺丝辊分别连接有驱动装置， 可实现独立实时调速传动。
每根纺丝辊相对于水平面从一端到另一端平行设置。
每根纺丝辊相对于水平面从一端到另一端倾斜设置。
每根纺丝辊呈圆台形， 且呈渐变状， 圆台的锥度为 0-20度。 每根纺丝辊上设置有多个环形槽。
每根纺丝辊上设置有隔离环。
每根纺丝辊长度为 700〜1800mm， 直径为 50〜500mm。
所述纺丝装置还包括辅助辊， 所述辅助辊至少为一根， 且平行于其中一纺 丝辊设置。
所述辅助辊连接有驱动装置， 可实现独立且实时调速转动。
所述纺丝辊转速为 30-1300转 /分。
所述辅助辊转速为 30-1500转 /分。
本发明具有以下优点：
1、 本发明的纺丝辊相对于纺面的操作面横向设置， 横向设置后的纺丝辊两 端固定，所以能够在半连续高速纺丝机的基础上实现纺速的提高， 并且保证纺丝 辊能稳定的转动， 不会发生晃动，避免了纺丝时丝条由于纺丝辊晃动而产生相互 缠绕、断丝等问题。 同时由于纺丝辊横向设置后即使提高纺速也能够保证丝条反 应充分， 丝条不会产生毛剌等问题， 也保证了丝条在纺丝过程中的均匀性， 在保 证纺丝质量和提高纺速的前提下， 生产效率得到提高。本发明由于纺丝辊相对于 纺面的操作面横向设置，所以纺丝辊的结构以及其传动结构得到简化，方便了工 人对纺丝辊的操作， 使得半连续纺丝机的工艺参数， 如： 多个纺丝辊的转速等更 容易控制。 本发明可在现有的 R535半连续纺丝机上直接进行改造， 所以改造成 本低， 有利于设备的升级换代。
2、 本发明的半连续高速纺丝机的纺丝辊横向设置， 便于对每个纺丝辊独立 控制， 更方便对于每个纺丝辊单独提速。
3、 本发明的半连续高速纺丝机的纺丝辊横向设置， 便于实时快速调整所生 产丝条的规格， 如将生产 40D的丝条更换为生产 60D、 120D, 150D， 200D等， 也 便于实时快速调整所生产的丝条品种， 如复合丝、 异形丝、 扁平丝等。 提速或者 变换品种时， 不需要停机更换传动齿轮。
4、 纺丝辊相对于纺面的操作面横向设置， 解决了纵向安装时工人操作空间 小的问题，且需要增加纺丝辊长度时， 只需要稍稍在水平面上将纺丝辊倾斜一定 的角度， 就可以在不牺牲工人操作空间的同时增加纺丝辊长度，增加丝条行走的 时间， 使反应更充分， 且能够有效防止丝条缠绞在一起。 同时， 操作工人能够方 便的对纺丝辊上的丝条进行操作，避免了现有的纺丝辊上丝条出现问题后， 操作 工人需要在多个离心缸和电锭之间穿梭，才能到达指定位置对丝条进行处理的问 题， 节约了工人处理丝条的时间。
5、 本发明的纺丝辊相对于纺面操作面横向设置， 整个半连续离心纺丝机只 需要 1根纺丝辊就能实现所有功能，相比于现有技术的半连续纺丝机需要 12根、 18 根或者更多的纺丝辊的技术方案， 本发明减少了纺丝辊数量、 降低了纺丝机 的制造成本， 且整体的控制系统得到了简化， 有利于程序化控制。
6、 纺丝辊均相对于纺面为横向设置， 有利于工艺控制更加优化， 也便于控 制。
7、 纺丝辊均相对于纺面操作面为横向设置， 丝条在纺丝辊上行进的路程变 长， 增长了丝条牵伸、 凝固和去酸的时间， 有利于丝条的成型， 特别是对于减少 并丝、 毛剌、 断丝等， 具有特别良好的技术效果。
8、 纺丝辊均相对于纺面操作面为横向设置， 减少了纺丝辊的数量， 且缩小 了整个半连续纺丝机的体积，减小了其占地面积和重量， 能降低半连续纺丝机的 制造成本。
9、 本发明纺丝辊的两端分别固定在机架两侧的上方， 在高速纺丝时， 纺丝 辊不会发生晃动，纺丝稳定，减少了断丝毛剌的产生量，纺丝辊连接有驱动装置， 可实现独立且实时调速转动， 独立驱动纺丝辊， 在改变纺丝品种， 例如扁平丝、 异形丝以及纺丝速度时控制容易， 快速。
10、 本发明的纺丝辊可以相对于水平面从一端到另一端平行设置， 也可以 相对于水平面从一端到另一端倾斜设置，纺丝辊相对于水平面从一端到另一端倾 斜设置有利于丝条分丝到卷绕装置中。
11、 将纺丝辊设为圆台形， 且呈渐变状， 圆台的锥度为 0-20度， 锥度为 0 度时就是圆柱状的纺丝辊， 圆台形，且呈渐变状的纺丝辊一端的直径大于另一端 的直径， 将粘胶长丝缠绕在这样的纺丝辊上， 由于纺丝辊的辊径逐渐变大， 粘胶 长丝在纺丝辊上进行螺旋线式的运行得到了有效的拉伸，进一步提高了粘胶长丝 的拉伸强度。
12、 在纺丝辊上设有多个环形槽， 在纺丝辊上设置环形槽， 纺丝时， 将丝条 限制在环形槽内， 丝条不会发生窜位， 每根丝条就不会相互缠绕， 同时环形槽还 能对丝条进行有效的拉伸， 有利于丝条强度的提高。
13、 在纺丝辊上设置有隔离环， 纺丝时， 将丝条限制在隔离环之间， 丝条不 会发生窜位，每根丝条就不会相互缠绕，同时隔离环还能对丝条进行有效的拉伸， 有利于丝条强度的提高。
14、 纺丝装置还包括辅助辊， 辅助辊至少为一根， 且平行于纺丝辊设置。 增加辅助辊的目的是为了便于工人取出废丝， 当出现废丝的时候， 工人将废丝引 入辅助辊， 很容易的将废丝取出， 然后再将正常的丝条引入纺丝辊上。
15、 辅助辊连接有驱动装置， 可实现独立且实时调速转动， 方便工人适时 取出废丝， 操作简单易行。
16、 纺丝辊相互平行设置， 纺丝辊相对于水平面从一端到另一端平行设置， 这样安装的纺丝辊振动小， 纺丝稳定， 便于操作与安装。
17、 纺丝辊相互平行设置， 纺丝辊相对于水平面从一端到另一端倾斜设置， 这样的安装方式， 可以增大纺丝辊的长度， 增大了丝条的行程， 延长了丝条的成 形时间， 有利于丝条质量的提高。
18、 本发明纺丝辊的数量为三根或者四根， 所有纺丝辊均相互平行设置， 三根或者四根纺丝辊不仅增加了丝条成型时间， 保证了丝条的成型质量， 同时三 根或者四根纺丝辊起到了很好的牵伸、凝固和去酸作用， 增加了丝条的强度， 减 少了丝条表面的毛剌， 纺丝辊均相互平行设置便于纺丝辊的安装和丝条的行进。
