The utility model discloses a stripping roller of a wire laying machine, which comprises a mandrel, an installation flange, a middle support and several stripping pipes. Installation flanges are installed at both ends of the mandrel. Several stripping pipes are evenly connected between the installation flanges at both ends and are circularly distributed. The utility model is characterized in that the middle part of the mandrel is provided with an intermediate support, a middle support and an installation flange at both ends. There are several installation holes in the circumference. There are a step at both ends of the stripping pipe. The gap between the step and flange installation holes is matched. The gap between the stripping pipe body and the supporting installation hole is matched. The diameter of the step is smaller than the outer diameter of the stripping pipe body. The steps and flange installation holes are fixed by welding or riveting. The gap between the adjacent stripping tubes should not be greater than 0.1 mm. The utility model can pat the tow intermittently through centrifugal force before it has time to follow the circle of the tapping roll, thereby avoiding the winding roll between the tow and the tapping roll, and is convenient for cleaning and efficient continuous production.
【技术实现步骤摘要】
一种铺丝机的剥丝辊
本技术涉及一种铺丝机的剥丝辊,尤其适用于二步凝胶法纺制高强高模聚乙烯纤维的铺丝工序,属于纺织机械领域。
技术介绍
高强高模聚乙烯纤维大多采用凝胶法纺丝工艺,并且纺丝系统与牵伸系统分为两步进行。从纺丝系统出来的丝束必须通过铺丝机构铺展在丝桶内并停留一段时间,再进行牵伸系统的萃取和牵伸。常规的铺丝机构很容易因为丝束跟随出丝辊绕行造成缠辊,所以必须设置剥丝辊部件。本申请人在ZL201420274331.X技术专利中提出了《一种带有剥丝辊的铺丝机》,剥丝辊由芯轴、两侧法兰和若干根剥丝管组成,两侧法兰安装在芯轴上的两侧,若干根剥丝管均布连接在两侧法兰之间并呈圆周分布,剥丝管分布圆轮廓尺寸与出丝辊的外径相等。剥丝辊的转向与出丝辊的转向相同,剥丝辊的转速等于或者大于出丝辊的转速。实际生产运行中,该铺丝机较好地避免了缠辊现象,但由于该结构的剥丝管在圆周上均布时,相邻管之间存在间隙,丝束中的毛丝、误操作产生的断丝很容易积存在剥丝辊内部,有时会严重影响正常纺丝的顺利进行。因此,这种剥丝辊的结构还需要进一步改进。
技术实现思路
本技术的目的是提供一种铺丝机的剥丝辊,以克服现有技术存在的上述缺陷。本技术的技术方案为:一种铺丝机的剥丝辊,它包括芯轴、安装法兰、中间支承和若干根剥丝管,在芯轴的两端分别安装有安装法兰,若干根剥丝管均布连接在两端安装法兰之间并呈圆周分布,在芯轴中间部位设有中间支承,中间支承及两端的安装法兰中呈圆周均布有若干安装孔,剥丝管两端分别设有一段台阶,台阶和法兰安装孔的间隙配合,剥丝管管身与支承安装孔间隙配合,台阶的直径小于剥丝管管身的外径,台阶和 ...
