[0002] The existing cigarette machine cutter head mechanism structure is composed of bearing seat, half shaft, ejector rod, short shaft (half circle), deep groove ball bearing, skeletonless sealing ring, sleeve, pin, compression spring and seat. The compression air in the seat pushes the sleeve, the sleeve pushes the short shaft to the right, the short shaft pushes the ejector rod to move to the right through the deep groove ball bearing, and the ejector rod pushes the ratchet mechanism to cut. The deep groove ball bearing in the cutting mechanism can bear large radial force, but cannot bear large axial force. The cutting needs axial thrust, and the bearing is easy to wear and damage during equipment operation. The skeletonless sealing ring in the seat is subjected to intense friction when the bearing is damaged, is heated and aged, and the sealing fails, so that the cutting action cannot be completed. The hole for installing the bearing is a blind hole, the damaged bearing cannot be taken out from the ejector rod bearing hole, the ejector rod needs to be taken out from the cutter head, and the maintenance time is long. The sleeve, ejector rod, short shaft, bearing, sealing ring and half shaft need to be replaced during maintenance, and the maintenance cost is high.
