摘要: 针对聚丙烯(PP)熔喷料的生产特点,分析了原有单板式换网装置的缺点,提出了更适用于PP熔喷料挤出生产的双滑柱式换网装置设计方案,并在实际应用中加以改进,由双柱两工位改为双柱四工位,解决了换网时出现的断条及漏料问题,实现了挤出生产的连续化,并降低了生产成本。

Abstract: The disadvantages of single-plate screen changing devices were analyzed based on the characteristic of polypropylene melt-blown resin. A double-plate screen changing device was proposed in which the original two-station design was replaced with a four-station one. The problems such as breakage and leakage of polypropylene melt during the screen changing were avoided, and continuous and low-cost production was achieved.
