Improvement of filter rod forming device in KDF3 filter rod maker
[Objective]This study aims to address the issue of large circumferential standard deviation(sd)values of filter rods caused by the unreasonable design of the filter rod forming device in the KDF3 filter rod forming machine.[Methods]A new type of long arc outer folding plate and a new type of linear step-free sealing iron were designed and manufactured.[Results]After applying the improved forming device,the circumferential standard deviation(sd)value of the filter rods decreased by 24.3%,and the average non-roundness value of the filter rods decreased by 13.2%;before and after the improvement,the production stage waste remained stable with no significant changes.[Conclusion]The improved molding device can provide support the improvement of the circumference quality of the filter rods produced by KDF3 molding machine.
