京棉二厂从西德引进了九台半自动络筒机,该机的作用是将小锭纱按质量要求绕成大锭纱,它具有自动清纱、自动打结等功能。但使用中络筒效率只达70%左右,造成细纱积压、上下工序不平衡等问题。为了解决这些问题,首先要能及时了解半自动络筒机的运行情况。为 Jingmian No. 2 Plant has introduced nine semi-automatic winders from West Germany. The function of this machine is to wind small spindle yarns into large spindle yarns according to quality requirements. It has the functions of automatic yarn clearing and automatic knotting. However, the efficiency of windings in use is only about 70%, which causes problems such as the backlog of the spun yarn and unbalanced processes. In order to solve these problems, we must first understand the operation of the semi-automatic winder. for
