Abstract: To replace the tipping paper cutting blades in YJ27 filter assembler quickly and reduce the consumption of spare parts, a special fixture was designed. The fixture is composed of a positioning block, an acrylic cover plate and pointless set screws. With the special fixture, a single cutting blade can be replaced dispensing with removing the paper cutter drum. Fastening the pointless set screws can prevent the new cutting blade from moving during installing and ensure accurate blade setting. The designed fixture was tested on YJ27 filter assemblers in Jinan Cigarette Factory. The results showed that compared with cutter drum replacement or empirical maintenance, the average maintenance time reduced by 12.8 or 7.6 min respectively. The average monthly consumption of cutting blade per filter assembler decreased from 7.8 blades to 2.3 blades. This technology provides technical supports for promoting the maintenance efficiency of making and assembling machine and reducing the consumption of spare parts.
