YB47型包装机铝箔纸润滑装置的改进

Improvement of aluminum foil lubricating device in YB47 packer

为解决YB47型包装机铝箔纸润滑装置在生产过程中发生管路吸不上油、过滤片堵塞以及油雾器渗漏等问题，对该装置进行了改进。选用可以调节喷油量的气体雾化喷雾啧嘴替换原喷嘴。拆除油雾器，重新设计储油杯用于储存润滑油，设计容量为2000mL，可满足设备运行200h的需求。通过试验确定润滑装置的主要设计参数：气源压力为150kPa；铝箔纸润滑功能在机器运行速度200—550包／min区间内处于开启状态，喷嘴以喷油30s、停顿5s的循环方式间歇对铝箔纸进行润滑；喷嘴安装高度为距离铝箔纸输送平台20mm。结果表明，改进后系统结构简单，运行稳定，喷油量控制在（10±0．8）mL／h范围内，喷油宽度值控制在（20±1．5）mm范围内，有效解决了喷嘴堵塞、润滑油渗漏等问题，保证了铝箔纸的润滑效果，提高了铝箔纸折叠品质，降低了设备的运行成本。

To solve the problems of interrupted oil supply in pipeline, filter pad jam and atomizer leakage, the aluminum foil lubricating device in YB47 packer was improved as following： 1） replacing original nozzle by an pneumatic adjustable atomizing nozzle; 2） removing oil atomizer and designing a new lubricant container with a designed volume of 2 000 mL, enough to support the equipment running for 200 hours. The major design parameters for the lubricating device determined via experiments were air pressure 150 kPa; foil lubricating functioning while machine running in a speed range of 200-550 packet/min; nozzle： spraying duration 30 sec at 35 sec interval; the installation height of nozzle 20 mm above aluminum foil conveying platform. The results showed that the improved system was simple in structure and ran stably, the amount and width of sprayed lubricant were controlled within 10±0.8 mL/hour and 20±1.5 mm, respectively. Aluminum foil was well lubricated and folded, and the running cost of equipment was reduced.
