线缆行业目前常用的机械放线张力调节机构有二种:一种是抱荷摩擦式,如图(1)所示;另一种是端面摩擦式,如图2所示。但这二种调节张力的方法其缺点均为调节张力变化过大,有润滑与无润滑相差较大,放线不平稳,张力不均匀,可靠性差,调节也不够方便,加上没有大概的数字概念,工人心中没有数。虽然螺纹调节位置每次一样,但其张力实际可能相差很大,所以小线薄层挤出及光纤的二次被复很难达到理想的放线张力。
There are two kinds of mechanical pay-off tension adjusting mechanisms commonly used in the cable industry at present: one is holding the load friction type, as shown in the figure (1); the other is the face friction type, as shown in FIG. 2. However, these two methods of adjusting tension have the disadvantages of adjusting excessive tension, varying lubrication and non-lubrication, uneven pay-off, uneven tension, poor reliability and inconvenient adjustment, and there is no approximate figure Concept, the number of workers in mind. Although the thread adjustment position the same time, but the tension may actually vary greatly, so a small thin-layer extrusion and the second fiber complex is difficult to achieve the ideal pay-off tension.
