The Influence of Nipper Machine Parameters in New Comber on Nipper Holding Process Performances

That finding out the influence of nipper machine parameters on nipper holding process performances in comber has biggish direction means on most parameters choice of comber and new comber design and use. Using resolution way of machine moving analysis means, on the base of nipper machine structure analysis and moving modeling, by computer, nipper process performances in condition of different eccentric shaft parameters on new comber were calculated and analysed, the relations between eccentric shaft speed ratio, steeve length and nipper opening amount, opening-closing timing, nipper pressure were discussed. Conclusions indicate that: in certain range, the decrease of eccentric shaft speed ratio and steeve length can make nipper opening timing advance and nipper opening amount increase before detaching beginning, which is beneficial to cotton-cluster rising advanced combed by cylinder and comber detaching-overlapping work.
