目的 研发一种多工位高速真空包装机， 并对真空包装袋包装效果进行评价。方法 采用多工位协同工作装置的设计与制造技术、 无真空室呼吸式抽真空技术、 全自动协同智能控制技术等技术集成方法， 设计和研发一种多工位高速真空包装机， 并采用国家标准对真空茶叶袋进行评价。结果所研发的多工位真空包装机包装速度大于40次/分钟。在压强为50 kPa的条件下， 10个真空茶叶袋样品均不破裂或渗透， 最低绝对真空度达到小于1.33 kPa的要求。结论 研发的多工位高速真空包装机生产效率高， 包装效果好。

The aim of this study was to develop a high-speed vacuum packaging machine with multiple work stations and evaluate its efficacy. By use of technology integration combining the design and manufacture technology of a device with multiple stations working in coordination, breathing style vacuum technology without vacuum chambers and automatic intelligent control technology of multiple stations, a high-speed vacuum packaging machine with multiple work stations was designed and manufactured. A series of vacuum tea packages were tested based on national standards. The new high-speed vacuum packaging machine with multiple work stations had a production speed of over 40 times/min. None of the ten tested tea vacuum packages was broken or permeated under a pressure of 50 kPa. The minimum resolute vacuum was less than 1.33 kPa as required. The new high-speed vacuum packaging machine with multiple work stations had a high production rate and its packaging efficacy was good.
