Description

离心纺装置及平面接收式离心纺自动生产设备 技术领域
本发明涉及纺织技术领域，尤其涉及一种离心纺装置及使用该离心纺装置的平面接收式离心纺自动生产设备。
背景技术
离心纺是一种能够同时适用于溶液纺和熔融纺的新型纺丝技术。离心纺在纺丝过程中，通过高速旋转的喷丝器所产生的离心力将喷丝器内部的纺丝溶液由微孔射出并形成细长纤维，其可制备的材料包括无机材料与高聚物材料，结合离心纺的产量高的特点及其纤维制品的优势，其制备的纤维产品并可应用于生物医药、空气过滤、能源等领域。
目前，对于离心纺丝来说，其纤维的成型机理已经被深入研究，而待解决的技术问题在于如何实现离心纺连续大批量生产。首先是离心纺的供料及收集方式的改进，传统的离心纺供料系统为半连续供料系统，即每次进行离心纺实验时，通过注射器将纺丝溶液输入至喷丝器的储液腔体中，纺丝过程为非连续方式；对于收集方式，传统的环形收集方式不能实现批量生产；其次，则是关于离心纺的产量的提升，虽然作为新型纺丝技术来说，其产量明显优静电纺，但是与传统的纺丝技术产量还是较低，因此纺丝连续供料及收集方式是产业化研究的方向。
例如，申请号为CN201610424908.4的发明专利提供了一种二氧化钛/聚丙烯睛(TiO 2/PAN)微/纳米纤维膜的离心纺丝制备方法，其提出的离心纺设备包括，电机、纺丝头和收集棒；纺丝头安装在电机的转轴顶部并由电机带动转动，纺丝头内具有容纳纺丝溶液的空腔，纺丝头顶部设有注液口，纺丝头侧壁设有与空腔连通的喷丝孔，收集棒围绕纺丝头一圈设置。离心纺丝时，纺丝头由电机带动转动，纺丝溶液从纺丝头的喷丝孔中喷出，在喷丝孔与收集棒之间运动得 到拉伸，同时溶剂挥发，形成纤维，通过收集棒接收得到纤维膜；此种收集方式将纺丝固定在收集棒之间，获得的纤维为不连续的短纤，效率低，无法实现连续生产。
申请号为CN201820388681.7的专利提供了一种离心静电纺丝装置，包括离心纺丝喷头、设置于离复丝喷头上方的接收装置、驱动离心纺丝喷头的驱动机构以及用于使离心纺丝喷头和接收装置之间形成纺丝溶液所需静电场的供电装置，离心纺丝喷头圆周径向间隔设有若干个出丝孔，离心纺丝喷头与纺丝溶液输送装置相连；此装置中接收装置设在离心纺丝喷头的上方并且接地，在离心力和电场力作用下拉伸从离心纺丝喷头的纺丝射流，此种静电方式不但不能实现连续生成，而且存在能耗过大、操作性低、安全系数低的问题。

具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请以下将结合附图对本发明各实施例的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所得到的所有其它实施例，都属于本发明所保护的范围。
下面通过具体的实施例子并结合附图对本发明做进一步的详细描述。
实施例1
请参阅图1至图11所示，本发明提供了一种平面接收式离心纺自动生产设备100，用于自动生产离心纺纤维网5。该平面接收式离心纺自动生产设备100包括用于制备离心纺纤维网5的离心纺装置1、用于将离心纺纤维网5缠绕成卷的收卷装置3以及设置于离心纺装置1与收卷装置3之间将离心纺纤维网5压实的压实装置2。在本实施方式中，离心纺装置1、压实装置2以及收卷装置3按照离心纺纤维网5的运动方向从前到后依次布置，离心纺装置1纺制出离心纺纤维网5后，离心纺纤维网5经过压实装置2压实，然后导入收卷装置3，收卷装置3将离心纺纤维网5缠绕成卷。
请参阅图2至图5并结合图1所示，离心纺装置1包括机架11、纺丝装置13、为纺丝装置13提供纺丝液的供料装置12、用于收集纺丝装置13喷出的离心纺纤维的收集装置14以及温控装置15。其中，收集装置14设置于纺丝装置13下方，以使纺丝装置13喷出的离心纺纤维附着在收集装置14的表面，实现 了平面接收离心纺纤维。
请参阅图3至图5所示，纺丝装置13包括喷丝装置133和带动喷丝装置133沿收集装置14的延伸方向(即离心纺纤维网5的运动方向)的垂直方向水平往复运动的横移装置132，使得喷丝装置133喷出的离心纺纤维可以沿收集装置14的宽度方向均匀覆盖在整个收集装置14上。如此，实现了宽幅非织造生产。
横移装置132固定安装在机架11上。横移装置132包括与机架11连接的固定支架1321、安装在固定支架1321上的横移运动单元1322、安装在横移运动单元1322上的滑块(未标号)、与滑块连接的安装板1323以及安装在安装板1323上的两根横移支杆1324。如此设置，横移运动单元1322通过安装板1323驱动横移支杆1324做水平运动。
在本实施方式中，两套喷丝装置133对称安装在两根横移支杆1324的两端。需要说明的是，喷丝装置133的套数可以根据对离心纺纤维网5的厚度要求进行设置，具体不予限制。
喷丝装置133包括与供料装置12连接的缓存罐、喷射离心纺纤维的喷丝器1340、连通缓存罐与喷丝器1340的导料管1344、套设于导料管1344外周的空心轴1345以及驱动喷丝器1340旋转的动力部。导料管1344的一端伸入缓存罐内，另一端伸入喷丝器1340内，以将缓存罐内的纺丝液引入喷丝器1340内，且导料管1344与空心轴1345的内壁不接触，避免了工作过程中由于摩擦导致设备故障，保证了设备正常运行。
缓存罐包括储存主体1342、端盖1343以及密封连接二者的密封圈，以防止纺丝溶液泄漏。例如，密封圈可以为耐腐蚀橡胶垫。端盖1343上安装有与供料装置12连接的接头，供料装置12通过该接头将纺丝溶液泵入缓存罐内。特别的，储存主体1342的侧壁上设置有透明的钢化玻璃板1341，以便于操作者实时观察缓存罐内纺丝溶液的剩余量。
导料管1344的上端通过螺纹连接固定在缓存罐内，固定连接处加装耐腐蚀橡胶垫进行密封处理。当然，导料管1344与缓存罐的连接方式并不以此为限，只需保证二者之间密封连通即可。
动力部包括具有输出轴的第一电机1337、主动带轮1338、从动带轮1339以及同步带1346。主动带轮1338通过键连接固定安装在第一电机1337的输出轴上，从动带轮1339通过键连接固定安装在空心轴1345上，同步带1346套在主动带轮1338与从动带轮1339上。由于喷丝器1340固定安装在空心轴1345下端，当第一电机1337驱动主动带轮1338旋转时，主动带轮1338通过同步带1346和从动带轮1339驱动空心轴1345转动，进而驱动喷丝器1340旋转。
喷丝器1340上加工有至少一个通孔1348，在喷丝器1340高速旋转时，纺丝溶液可从通孔1348内射出。
为了调整喷丝器1340的高度，以保证喷丝器1340与收集装置14之间的合理距离，喷丝装置133还包括调节喷丝器1340与收集装置14之间的距离的高度调节装置。
高度调节装置包括用于固定安装喷丝器1340的支撑板1353、与支撑板1353连接的导杆1334、套设于导杆1334外周的直线轴承1335、安装在横移支杆1324上的基板1336、与导杆1334的另一端连接的调节板1333及通过轴承座安装在调节板1333上的调节丝杆1332。直线轴承1335固定安装在基板1336上。调节板1333上设置有螺母1350，且调节板1333设置于基板1336的上方，调节丝杆1332与螺母1350配合调节支撑板1353与收集装置14之间的距离。
在本实施方式中，设置有两根直线轴承1335，对应的，设置有两根直线轴承1335。两根导杆1334分别套在两根直线轴承1335内。优选地，调节丝杆1332上端固定安装有手轮1331。如此设置，手动旋转手轮1331，驱动调节丝杆1332在螺母1350内转动，调整调节板1333与基板1336之间的距离，从而调整1324和1353之间的距离，由于横移支杆1324固定不动，进而使得支撑板1353上的喷丝器1340与收集装置14之间的距离发生变化。
喷丝装置133还包括用于固定缓存罐的缓存罐支架1351和用于固定第一电机1337的直线电机支架1352，且缓存罐支架1351与直线电机支架1352均固定在支撑板1353上。
即，当喷丝器1340高速旋转时，纺丝溶液从喷丝器1340上的通孔1348内 射出，在空气阻力、流体的黏性力及自身的惯性力的共同作用下，在射流轴向上产生一对轴向拉伸力的作用下，在扇形区域形成扩散性射流，此时纺丝半径逐渐变大；紧接着，由于喷丝器1340的高速旋转，其所造成的气流场开始对射流进行引导性牵伸，并在重力的作用下，射流轨迹逐渐向下偏移，且纺丝半径呈逐渐变小，这样经过射流的产生、拉伸、颈缩的过程后最终形成的纤维呈螺旋线下降并收集于收集装置14上，最终形成均匀的离心纺纤维网5。
请参阅图6并结合图1与图2所示，供料装置12固定安装在机架11底部。供料装置12包括内装有纺丝溶液的储料罐121和与储料罐121通过管路连通的流量泵123。流量泵123与若干个缓存罐通过管路连接，同时为若干个缓存罐供料。流量泵123将储料罐121内的纺丝溶液泵入若干个缓存罐内。
特别的，流量泵123和缓存罐之间的管路上设置有电动开关阀124。流量泵123一直处于工作状态，通过电动开关阀124的开关控制纺丝溶液是否进入缓存罐内。
储料罐121内设置有液位计122。当储料罐121内的纺丝溶液液位低于液位计122的位置时，液位计122发送信号至控制系统16，控制系统16向操作人员发出警报，操作人员向储料罐121内补料。
缓存罐上也设置有液位计122；当若干个中的一个缓存罐内的纺丝溶液低于液位计122高度时，缓存罐内的液位计122发送信号至控制系统16，控制系统16控制与该缓存罐对应的电动开关阀124打开，管路内的纺丝溶液进入缓存罐内。
流量泵123和缓存罐之间的管路上还设置有流量计125。当电动开关阀124打开向缓存罐供料时，流量计125检测进入缓存罐内的纺丝溶液的流量，当达到设定值后，流量计125向控制系统16发送信号，控制系统16控制控制电动开关阀124关闭，停止向缓存罐供料。
储料罐121上安装有搅拌器126。在向缓存罐供料的同时，搅拌器126对储料罐121内的纺丝溶液进行搅拌。
请参阅图7所示，收集装置14包括安装在机架11上的传动牵引装置141、 收集带142以及设置于收集带142下方用于支撑收集带142的水平支撑板143。水平支撑板143用于保证收集带142处于水平状态，便于收集由纺丝溶液形成的纤维网。收集带142为环形带，套在传动牵引装置141上，传动牵引装置141带动收集带142做固定方向的循环运动。
如此，当喷丝器1340高速旋转时，其内的纺丝溶液喷出，喷出的瞬间由于离心力和重力的作用，纺丝溶液迅速成丝，并附着在收集带142上形成纤维网；随着收集带142向前运动，纤维网均匀平铺在收集带142上。
收集带142的材料为聚四氟乙烯，防止了其被纺丝溶液腐蚀。
优选地，收集装置14还包括设置于水平支撑板143下方的抽风装置(未图示)，同时，将收集带142制成网状结构，并在水平支撑板143上加工密布的通孔。如此设置，可以在收集带142表面形成负压，负压将附着在收集带142表面的离心纺纤维网5吸附在收集带142上，防止了由于纺丝溶液喷射形成的纤维网较轻，收集带142运动时空气将纤维网吹起而脱离收集带142的情况发生，提高了生产效率。
其中，收集带142的运动速度为0-10m/min。根据实验测定，喷丝器1340与收集带142之间的距离介于0-100mm时，纺纱效果最好。
平面接收式离心纺装置1还包括环设于纺丝装置13四周的隔离罩板(未图示)。隔离罩板与收集带142形成容纳纺丝装置13的半封闭腔体，半封闭腔体内设置有控制半封闭腔体内的温度的温控装置15。
温控装置15固定安装在机架11上部，包括若干个电加热管151及若干套制冷装置152。若干个电加热管151均布在纺丝装置13上方，可对半封闭腔体内的空气进行加热，保证半封闭腔体内的温度保持在一定范围内，为纺丝提供了适宜的温度环境。若干套制冷装置152固定安装在机架11顶部。当纺丝环境的温度较高时，制冷装置152可对对半封闭腔体内进行降温。
离心纺装置1还包括与纺丝装置13、供料装置12、温控装置15及收集装置14信号连接的控制系统16。控制系统16，控制整套装置自动运行，其主要控制工艺参数包括：供料量、喷丝器1340的转速、纺丝环境的温度、收集带142 的运动速度。
具体来讲，在离心纺装置1的工作过程主要包括如下步骤：
人工通过控制系统16设定生产参数，包括环境温度、喷丝器1340转速、纺丝纤维厚度、收集带的移动速度；控制系统16根据纺纱纤维的设定厚度值选择喷丝装置133的个数；
控制系统16控制供料装置12向纺丝装置14供料；由流量计126及液位计122共同检测缓存罐内纺丝溶液的体积，当监测值达到设定值后，停止供料；
控制系统16控制温控装置15对机架11上的半封闭腔体进行温度调节，保证纺丝原料处于最佳纺丝状态；
同时控制系统16控制传动牵引装置141运行使得收集带142的移动速度达到设定值；
最后，启动第一电机1337，喷丝器1340开始高速旋转进行喷丝，喷丝形成的纤维呈螺旋线下降并收集于收集带142上，最终形成均匀的离心纺纤维网5。
需要说明的是，初始阶段制备的离心纺纤维网5由人工牵引通过压实装置2，缠入收卷装置3内进行收卷。
请参阅图8至图9所示，压实装置2包括压实机架201、安装在压实机架201上的压辊210、转动辊207及用于固定安装压辊210的压辊安装板211。压辊安装板211的两端设置有滑块209，压实机架201上设置有供滑块209滑动的滑轨213。压实装置2还包括设置于压辊安装板211上方的气缸202，气缸202的活塞杆上安装有浮动接头212，该浮动接头212的一端抵接于压辊安装板211，以实现通过活塞杆的伸缩驱动压辊210沿滑轨213上下滑动。
在本实施方式中，压辊210通过轴承座固定安装在压辊安装板211上，两个气缸202对称固定安装在压实机架201上部，两根滑轨213分别固定安装在压实机架201两侧，滑块209安装在滑轨213上。转动辊207通过轴承座固定安装在压实机架201上。如此，气缸202通过活塞杆的伸缩带动浮动接头212将安装在压辊安装板211上的压辊210向下推，使得压辊210与转动辊207贴合并压紧，以将通过压实装置2的离心纺纤维网5压实。
压实装置2还包括驱动转动辊207转动的驱动部，其包括具有输出轴的驱动电机206、安装在输出轴上的压实主动链轮205、安装在转动辊207上的压实从动链轮203以及传动连接压实主动链轮205与压实从动链轮203的压实链条204。驱动电机206带动压实主动链轮205驱动压实从动链轮203转动，以带动转动辊207转动。
在本实施方式中，驱动电机206固定安装在压实机架201下部；压实主动链轮205通过键连接固定安装在驱动电机206上；压实从动链轮203通过键连接固定安装在转动辊207一端；压实链条204套在主动链轮和从动链轮上；驱动电机206通过主动链轮和压实链条204驱动压实从动链轮203转动；压实从动链轮203带动转动辊207转动；如此，离心纺纤维网5被压实的过程中，转动辊207转动，起到了对离心纺纤维网5的牵引作用，防止了在压实过程中，离心纺纤维网5被收卷装置3扯断。
请参阅图10至图11所示，收卷装置3包括上收卷机架306、沿离心纺纤维网5的运动方向依次设置在上收卷机架306上的第一导向辊303、限位辊302、张力调整辊305、第二导向辊301以及收卷辊319；所述离心纺纤维网由所述第一导向辊导入所述收卷装置，由所述张力调整辊和所述第二导向辊导向后缠绕在所述收卷辊上。离心纺纤维网5由第一导向辊303导入收卷装置3，由张力调整辊305和第二导向辊301导向后缠绕在收卷辊319上。特别地，限位辊302设置在第一导向辊303的斜上方，保证了离心纺纤维网5只在第一导向辊303和限位辊302之间。
上收卷机架306两侧安装有导向块304，导向块304内设置有收容张力调整辊305的端部的凹槽。张力调整辊305的两端分别安装在两个导向块304的凹槽内，并在凹槽内滑动。如此，张力调整辊305压在离心纺纤维网5上，靠自身重力调整离心纺纤维网5的张紧力。
上收卷机架306两侧还设置有卡紧机构317，收卷辊319两端分别卡在两套卡紧机构317内，卡紧机构317将收卷辊319及其两端的轴承卡在卡紧机构317内的凹槽内，收卷辊319在卡紧机构317内旋转自如。当完成收卷功能后，通 过手动操作卡紧机构317，收卷辊317可轻易脱离卡紧机构317。

如此，收卷电机312通过收卷主动链轮314、收卷链条315驱动收卷从动链轮316转动，收卷从动链轮316带着收卷从动轴321一起转动，收卷从动轴321转动时带着主动齿轮320转动，主动齿轮320将动力通过从动齿轮318传递给收卷辊319，这样收卷辊319可持续转动，保证了收卷工作的顺利完成。

4)采用实施例三中的设备进行纺丝，通过控制系统调整测试参数，纺丝环境温度设置为25℃，选用一套喷丝装置，喷丝器的转速设置为3000r/min，喷丝孔径为0.2mm，收集带到喷丝器之间的距离为50mm。
实施例八至实施例十
实施例八至实施例十与实施例七的不同之处在于，实施例八中，PAN的质量分数为19％；实施例九中PAN的质量分数为20％；实施例十中PAN的质量分数为21％；其它条件均与实施例七一致。
通过对比不同浓度条件下纤维直径的频率分布直方图(图18)可以看出，纤维直径大部分布在1-5μm的范围内，其中21％组分有少量的纳米纤维，同时随着浓度的增加，纤维的直径越来越大；因为，随着溶液浓度的增加，溶液粘度越来越大，分子链间的作用力越来越大，在同等转速条件下，分子链越来越 难以牵伸，以至于直径会变大。
实施例十一至实施例十四
请参阅图19至图22所示，与实施例五的不同之处在于，实施例十一中，喷丝器的转速设置为5000r/min；实施例十二中，喷丝器的转速设置为6000r/min；实施例十三中，喷丝器的转速设置为7000r/min；实施例十四中，喷丝器的转速设置为8000r/min；其它条件均与实施例五一致。
通过高速摄像机对其进行实时拍摄，选取0s、15s、30s和45s作为实验记录；在5000rpm-6000rpm的范围内，喷丝嘴射出的PVB纺丝溶液的所受到的离心力逐渐增大，并在惯性力的作用下及时摆脱了旋转的喷丝器的负压力场的作用，从而在喷丝器周围能够形成较好的纺丝轨迹。
实施例十五至实施例十八
请参阅图23所示，与实施例五的不同之处在于，实施例十五中，通过控制系统调整测试参数，将纺丝环境温度设置为10℃；实施例十六中，通过控制系统调整测试参数，将纺丝环境温度设置为25℃；实施例十七中，通过控制系统调整测试参数，将纺丝环境温度设置为40℃；实施例十八中，通过控制系统调整测试参数，将纺丝环境温度设置为55℃；其它条件均与实施例五一致。
温度为10℃时，此时PVB纺丝溶液呈现出典型的粘性行为；随着温度的升高，此时PVB纺丝溶液系统的弹性行为增大，在凝胶点之后，此时PVB溶液呈现出典型的弹性行为，并且没有平台发生，表明PVB溶液的凝胶化过程是一个物理过程。
实施例十九
与实施例五不同的是，实施例十九采用实施例一中的装备进行纺丝，实施例一中的喷丝器1340加工有通孔1348，纺丝溶液在喷丝器1340高速旋转时从通孔1348内射出。
实施例二十
请参阅图24至图25所示，与实施例五不同的是，实施例二十采用实施例四中的装备进行纺丝，实施例四中的喷丝器1340上安装有喷丝嘴1354，喷丝嘴 1354的结构形式为台阶形式；喷丝器1340内的纺丝溶液通过喷丝嘴1354射出。
通过高速摄像机对实施例五、实施例十九和实施例二十进行离心纺的过程进行捕捉，并在0s，5s，10s和15s四个时间节点上进行拍摄。
实施例五中，PVB纺丝溶液经锥形型喷丝嘴射出，经过拉伸、颈缩和固化，从而成为PVB纤维并以螺旋线为纺丝轨迹，在自身重力的作用下收集在纤维收集面上，由于纺丝轨迹的半径较大，因此PVB纤维受旋转的喷丝器的下方存在的负压力场的作用力小，纺丝轨迹的稳定性较好。
实施例十九中，PVB纺丝溶液变成液滴落在收集带上，无法在该条件下进行PVB离心纺。
实施例二十中，PVB纺丝溶液从台阶形式的喷丝嘴喷出，经过拉伸、颈缩和固化，从而成为PVB纤维并以螺旋线为纺丝轨迹，一方面在自身重力和在旋转的喷丝器的下方存在的负压力场的共同作用下收集在收集带上，另一方面由于收集在收集带上的PVB纤维受在旋转的喷丝器的下方存在的负压力场的作用下，趋向喷丝器的底部运动，从而缠绕在喷丝器的外壁及喷丝嘴上。
实施例二十一至实施例二十三
请参阅图26至图28所示，与实施例五的不同之处在于，实施例二十一中，喷丝孔径为0.25mm；实施例二十二中，喷丝孔径为0.41mm；实施例二十三中，喷丝孔径为0.64mm；其它条件均与实施例五一致。
通过高速摄像机对其实验过程进行捕捉，并于0s、15s、30s和45s这四个时间点进行实时捕捉；随着喷丝嘴孔径的减小，所制备的PVB纤维间的直径的表面均匀性则有所提高，但是所制备的PVB纤维中的复丝则越多，即一根PVB纤维中存在多根PVB纤维。
实施例二十四至实施例二十五
请参阅图29至图30所示，与实施例五的不同之处在于，实施例二十四中，收集带到喷丝器之间的距离为40mm；实施例二十五中，收集带到喷丝器之间的距离为60mm；
通过高速摄像机对其实验过程进行捕捉，并于0s、15s、30s和45s这四个 时间点进行实时捕捉。
随收集高度的增大，所制备的PVB纤维中的复丝则越多，即一根PVB纤维中存在多根PVB纤维，且PVB纤维间的直径不匀率逐渐变大。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明实施例技术方案。
