Design and application of cooling and cleaning device for MAX Secondary slitting circular knife in ZJ118 cigarette making machine group
To solve the problem of rough cut edges on the cigarette filters during the cutting process of double-length filter cigarettes by the MAX secondary slitting circular knife in the ZJ118 cigarette making machine group,due to the accumulation of glue scale and increase in notches on the circular knife,a circular knife cooling and cleaning device was designed.This device reduces the temperature of the circular knife by dripping lubricating oil into the felt material in the oiling trough.At the same time,it forms a fine and thin oil film to prevent the accumulation of glue scale.The negative pressure suction on the left wall of the device and the spraying pipe above the surface of the circular knife work together to recover the glue scale and debris from the filter rods on the surface of the circular knife,thus ensuring the blade of the circular knife is smooth and notch-free.Testing with the ZJ118 cigarette making machine group used in Xunyang Cigarette Factory showed that:(1)the temperature of the circular knife was reduced from above 50℃to below 45℃;(2)there was no accumulation of scale on the circular knife,no foam in the secondary slitting wheel knife gap,and no notches on the circular knife;(3)the occurrence of rough cut edges on the filter cigarettes decreased from 3 times/month to 0 times/month.This indicates that the designed device effectively solves the aforementioned problems and improves the process quality.
