Description

一种化纤用导丝机 技术领域
本发明涉及化纤设备领域，特别是涉及一种化纤用导丝机。
背景技术
在化纤生产的后纺流程中，在纤维丝束进入导丝机时，先要经过分丝棒进行分丝，将一大片纤维丝束分成宽度均匀的若干条纤维丝束带，以使得导丝机导丝均匀，各个纤维丝束受力状态相通，成丝均匀有弹性，但是，现有的导丝机，在分丝棒进行分丝时，丝束带被分开时，分界处的纤维丝束受力容易叠加到一起，且分丝完成后，重叠的纤维丝束不易分开，重叠处比其他丝束厚，以使得丝束的受力不均匀，无法形成均匀的纤维丝束，影响成品的质量。
发明内容
本发明针对上述技术问题，克服现有技术的缺点，提供一种化纤用导丝机，导丝机分丝棒上套设有截面为椭圆形的摩擦套，在纤维丝束通过分丝棒时，受椭圆形摩擦套导向作用，边界处的纤维丝束不会叠加在一起，分丝效果更好。
为了解决以上技术问题，本发明提供一种化纤用导丝机，包括机壳、分丝筒和压丝筒，分丝筒和压丝筒固定连接在机壳上，分丝筒位于压丝筒下方，并与压丝筒之间留有间隙，分丝筒包括分丝棒和分丝圈，分丝圈通过螺栓组件可拆卸连接在分丝筒上，分丝棒焊接在分丝圈上，其特征是：所述分丝棒的横截面为圆形，所述分丝棒外套设有横截面为椭圆形的摩擦套，椭圆形摩擦套的短轴处与分丝棒表面相切并固定连接。
技术效果：当纤维丝束通过分丝棒进行分丝时，纤维丝束被梭形的弧形面逐渐分开，使分丝效果好，但是摩擦套套在分丝棒上不稳定，受力易断裂或者脱落，所以将分丝棒的横截面设为圆形并与截面为椭圆形的摩擦套相切，才能使摩擦套与分丝棒之间固定住，不易因受力而发生变形或者断裂，且分丝棒焊接在分丝圈上，因分丝圈为可拆卸连接在分丝筒上，所以可以通过调节分丝圈 转动来调节分丝棒的角度，分丝棒可以根据所分纤维丝束的不同弹性，来调节分丝棒的位置，对于弹性较差的纤维，需要将分丝圈转动，使分丝棒向纤维丝束进入导丝机的方向倾斜，以使得分丝棒在离分丝筒较远的地方进行分丝，以使得纤维有足够的时间可以恢复原状，形成密度均匀的纤维丝束，在进行后续加工后，得到的纤维成品更好。
本发明进一步限定的技术方案是：
进一步的，摩擦套为陶瓷制成。
前所述的一种化纤用导丝机，分丝圈将分丝筒分成若干段压丝通道，分丝圈与分丝筒相接处设有圆角。
前所述的一种化纤用导丝机，压丝筒对应压丝通道处设有向外突出的压丝块。
前所述的一种化纤用导丝机，压丝块上设有圆弧形压丝层。
前所述的一种化纤用导丝机，压丝层为塑料制成。
前所述的一种化纤用导丝机，分丝筒内腔中空，内腔对应压丝块的位置设有横跨分丝筒内腔截面的支撑杆，且支撑杆位于分丝筒内腔截面的直径上
本发明的有益效果是：
(1)本发明中因纤维丝束通过分丝棒时，边界与摩擦套产生摩擦，容易使摩擦处的纤维丝束发生断裂或者卷曲现象，影响成丝质量，本方案中摩擦套为陶瓷制成，陶瓷表面光滑，摩擦力小，不将纤维丝束擦伤，得到的纤维成品更好；
(2)本发明中当纤维丝束分丝后，需要通过压丝通道，才能到达导丝机的导丝辊，分丝后的纤维丝束会平铺在压丝通道内，分丝圈与分丝筒相连处若为直角，会对纤维丝束的两边产生较大的摩擦，擦伤纤维丝束，影响成丝质量， 而将分丝圈与分丝筒相接处设为圆角，则位于压丝通道两侧的圆角光滑，并且与纤维丝束接触面积小，对纤维丝束产生的摩擦小，以使得纤维丝束畅通无阻的通过，得到的纤维成品质量更好；
(3)本发明中纤维丝束经分丝棒分丝后，需要的到厚度均匀的纤维丝束带，而纤维丝束经常发生叠加而部分变厚的现象，所以在压丝筒对应压丝通道处设有向外突出的压丝块，以使得纤维丝束带通过压丝通道时的高度被限制，可将叠加在一起的纤维丝束，通过压丝块的限制作用重新押回到原来的位置，以使得通过压丝通道的纤维丝束带厚度均匀，得到的纤维成品质量更好；
(4)本发明中因压丝块起限制纤维丝束带通过的高度，并修正纤维丝束走向的作用，所以会与纤维丝束带产生摩擦，容易刮伤纤维丝束，使纤维丝束带发生断裂或者卷曲的现象，影响成丝质量，本方案中将压丝块上设置弧形压丝层，可以减少压丝块与纤维丝束的接触面积，减小摩擦，以使得得到的纤维成品更好；
(5)本发明中因塑料制成的压丝层，表面光滑，而且质量小，不会对压丝筒产生较大负重，不会伤害到纤维丝束，而且光滑的表面提高纤维丝束通过的速度，提高了生产质量；
(6)本发明中因分丝筒伸出机壳部分长，所以需要尽量减轻分丝筒的重量，防止分丝筒伸出机壳处受剪力过大而发生断裂，所以将分丝筒内腔设为中空，因中空的内腔机械强度小，受力易变形，影响纤维丝束的加工，便在内腔对应压丝块的位置设置横跨分丝筒内腔截面额支撑杆，加强了分丝筒受力处的机械强度，防止分丝筒变形
(5)本发明中活动连接的分丝圈可调节分丝棒的角度，提前将纤维丝束分丝，使纤维丝束经分丝后更易恢复原状，横截面为梭形的分丝棒使纤维丝束更易进行分丝，且梭形的截面还可以帮助纤维丝束快速恢复，提高了纤维丝束的 质量，分丝棒上套设的陶瓷套、分丝筒与分丝圈相接处的圆角都可以使纤维丝束通过时的摩擦力减小，不会使纤维丝束发生卷曲，断裂的现象，纤维丝束分丝后再经过压丝块的限制，以使得通过压丝块的纤维丝束厚度、密度都均匀，得到的纤维成品质量好，且压丝块上的塑料弧形压丝层，光滑的塑料压丝层，使纤维丝束通过时受摩擦力小，不会使纤维丝束发生卷曲或者断裂的现象，分丝筒内腔中空，内腔对应压丝块的位置设有横跨分丝筒内腔截面的支撑杆，且支撑杆位于分丝筒内腔截面的直径上，降低了分丝筒的质量，并且保证了分丝筒的机械强度。

具体实施方式
本实施例提供的一种一种化纤用导丝机，结构如图1-5所示。
如图1,导丝机包括机壳2、分丝筒5和压丝筒3，分丝筒5包括用于分隔纤维丝束的分丝棒1，分丝棒的截面为圆形。
如图2，压丝筒3被紧固在机壳2上，分丝筒5还包括可拆卸连接在分丝筒5上的分丝圈4，分丝筒5和压丝筒3之间形成压丝通道10。
如图3，压丝筒3上设有压丝块6，将压丝通道10变窄，以使得纤维丝束带通过压丝通道10时的高度被限制，可将叠加在一起的纤维丝束，通过压丝块6的限制作用重新押回到原来的位置，以使得通过压丝通道10的纤维丝束带厚度均匀，得到的纤维成品质量更好，分丝圈4和分丝筒5相连接处设圆角9，减小纤维丝束通过时产生的摩擦力，当纤维丝束分丝后，需要通过压丝通道10，才能到达导丝机的导丝辊，分丝后的纤维丝束会平铺在压丝通道10内，分丝圈4与分丝筒5相连处若为直角，会对纤维丝束的两边产生较大的摩擦，擦伤纤维丝束，影响成丝质量，而将分丝圈4与分丝筒5相接处设为圆角9，则位于压丝通道10两侧的圆角9光滑，并且与纤维丝束接触面积小，对纤维丝束产生的摩擦小，以使得纤维丝束畅通无阻的通过，得到的纤维成品质量更好。
结合图4，压丝块6远离分丝筒5的一端套设在枢轴61上，枢轴61与压丝块6之间通过扭簧62相连。当官压丝块6受力时，因扭簧62发生形变，具有一定的摆动幅度，防止压丝块6压的过紧而损坏纤维丝。
如图4，在压丝块6上设有弧形的压丝层，因压丝块6起限制纤维丝束带通过的高度，并修正纤维丝束走向的作用，所以会与纤维丝束带产生摩擦，容易刮伤纤维丝束，使纤维丝束带发生断裂或者卷曲的现象，影响成丝质量，本方案中将压丝块6上设置弧形压丝层8，可以减少压丝块6与纤维丝束的接触面积，减小摩擦，以使得得到的纤维成品更好，且压丝层为塑料制成，因塑料制成的压丝层，表面光滑，而且质量小，不会对压丝筒3产生较大负重，不会伤害到纤维丝束，而且光滑的表面提高纤维丝束通过的速度，提高了生产质量，分丝筒5内腔中空，内腔对应压丝块6的位置设有横跨分丝筒5内腔截面的支撑杆7，且支撑杆7位于分丝筒5内腔截面的直径上，因分丝筒5伸出机壳2部分长， 所以需要尽量减轻分丝筒5的重量，防止分丝筒5伸出机壳2处受剪力过大而发生断裂，所以将分丝筒5内腔设为中空，因中空的内腔机械强度小，受力易变形，影响纤维丝束的加工，便在内腔对应压丝块6的位置设置横跨分丝筒5内腔截面额支撑杆7，加强了分丝筒5受力处的机械强度，防止分丝筒5变形。
如图5，分丝棒1上套设有横截面为椭圆形的摩擦套11，分丝棒1外套设有一圈截面为椭圆形的摩擦套11，当纤维丝束通过分丝棒1进行分丝时，纤维丝束被摩擦套11梭形的弧形面逐渐分开，完成分丝后，还可以随着摩擦套11的弧形面还原到原来的位置，使分丝效果好，提高了纤维丝束的质量，但是摩擦套11套在分丝棒1上不稳定，受力易断裂或者脱落，所以将分丝棒1的横截面设为圆形并与截面为椭圆形的摩擦套11相切，才能使摩擦套11与分丝棒1之间固定住，不易因受力而发生变形或者断裂，且分丝棒1焊接在分丝圈4上，因分丝圈4为可拆卸连接在分丝筒5上，所以可以通过调节分丝圈4转动来调节分丝棒1的角度，分丝棒1可以根据所分纤维丝束的不同弹性，来调节分丝棒1的位置，对于弹性较差的纤维，需要将分丝圈4转动，使分丝棒1向纤维丝束进入导丝机的方向倾斜，以使得分丝棒1在离分丝筒5较远的地方进行分丝，以使得纤维有足够的时间可以恢复原状，形成密度均匀的纤维丝束，在进行后续加工后，得到的纤维成品更好。
其中，摩擦套11为陶瓷制成，因纤维丝束通过摩擦套11时，边界与摩擦套11产生摩擦，容易使摩擦处的纤维丝束发生断裂或者卷曲现象，影响成丝质量，本方案中摩擦套11为陶瓷制成，陶瓷表面光滑，摩擦力小，不将纤维丝束擦伤，得到的纤维成品更好。
除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
