本文以国内80年代引进的KDF2滤棒成型机组(国产型号ZL22)为研究对象,针对该设备增塑剂补偿部分维修量较大、增塑剂补偿部分的皮碗易损坏,以及因该部分工作不正常而导致开机初始段滤棒增塑剂添加不足强制报废带来的原辅材料浪费较为严重的实际情况,利用液压的传递特性以及常态下空气与液体的弱亲水性的物理特性,设计了用空气作为抽吸阀的活塞,以推动增塑剂的流动,即通过软管中的流动的空气来替代原增塑剂补偿部分的皮碗改进方案,不仅解决了增塑剂补偿部分设计存在缺陷问题,而且该装置原先存在的渗漏现象从根本上得到了解决。
In this paper, the KDF2 filter rod making unit (domestic model ZL22) introduced in China in the 1980s is taken as the research object. In view of the large amount of repairing part of the plasticizer compensating part and the damaged bowl part of the plasticizer compensating part, Abnormal and lead to the initial stage of the boot filter plasticizer added less than the mandatory waste scrapped raw and auxiliary materials more serious waste of the actual situation, the use of hydraulic transmission characteristics and the normal physical properties of air and liquid weak hydrophilic design The use of air as a suction valve piston to promote plasticizer flow, that is, the flow of air through the hose to replace the original plasticizer compensation part of the cup bowl to improve the program, not only solved the plasticizer compensation part of the design There is a problem of defects, and the device’s original leakage phenomenon has been fundamentally resolved.
