Abstract

The installation method of the large hydro-generator stator bar slot lining paper comprises the following steps: Step 1, butt joint of the slide block extension section and the slide block; Step 2, raw material preparation; Step 3, starting of the feeding device and the cutting device; Step 4, glue scraping operation; Step 5, bar slot lining paper operation; Step 6, moving of the wrapped bar into Step 3 for continuous production. By using the slide block extension section, the horizontal position relationship between the discharge opening of the feeding and cutting device and the glue scraping and bar slot lining paper device can be adjusted, and the device can easily and efficiently complete the glue scraping and wrapping process of the bar. In combination with the adjustable slide block, the bar slot lining paper can be conveniently wrapped.
