In order to solve the problems that the operators use hand tearing or blade cutting to cut the forming paper when checking the process indexes such as the forming paper overlap,the application of glue in the middle line,the loosening of the silk bundle,and the curing effect of the filter rods,the cutting strength is not easy to be controlled,and the cuts are irregular and neat,and the damage to the silk bundle tissues and the filler of the silk bundle is easy to be caused which results in inaccurate checking,analysing,and judging,etc.The design of a cutting device for filter rods is based on the following principlesA filter rod cutting device is designed to cut the forming paper and filament bundles of filter rods completely and effectively without damaging the filament bundles and their internal filler particles,and to meet the cutting needs of filter rods of different specifications.The cutting device is easy to use,and the filter rod is cut neatly,which is convenient for the operator to check the process quality index of the filter rod;at the same time,it can avoid the phenomenon of folding and tearing of the forming paper,and also can avoid the generation of more debris such as paper dust,glue and other debris.And the round knife in the device,high safety,to protect the operator operation safety.
