Mix exponent number sinusoidal pattern non-circular gear reeling machine traverse mechanism
Technical field
The present invention relates to a kind of reeling machine traverse mechanism, be specifically related to a kind of exponent number sinusoidal pattern non-circular gear reeling machine traverse mechanism that mixes.
Background technology
The effect of traverse mechanism is that the strand that makes to be wound on little forms netted silk sheet, it affects that a sheet is shaped and the quality of dry mass, difficulty or ease that solution is moved back in rereeling and coiling loading amount number etc.Traverse mechanism must possess makes the strand of adjacent two layers filature not overlap and batch equably, and easy change when strand cuts off, even if roll up the function on the overlapping more limit of also not collapsing of strand in little limit.Traverse mechanism finally carry out member----the motion of cross winding bar is stroke motion and moves synthetic apart from motion.
At present, traverse mechanism on the reeling machine of selling on market at home, its stroke motion is mainly by three kinds of winding machines: cylindrical cam mechanism, and the type mechanism can realize the at the uniform velocity reciprocating motion of cross winding bar by changing cylindrical cam profile, but can produce very large impact in the time of commutation; The cyclic train of constant traverse and the combined mechanism of crank block, the type mechanism kinematic is more steady, but the characteristics of motion can not meet the demands, the silk sheet middle concave of formation, both sides are protruding, are unfavorable for the be shaped increase of increase degree of stable and silk sheet thickness of a sheet; The design of the variation cyclic train of journey and the combined mechanism of crank block, is conducive to increase the overlapping cycle, improves the flatness on silk sheet surface, but under constant condition of cycle, in the time that traverse reduces, winding angle also reduces.It moves apart from motion main by two kinds of winding machines: cylindrical cam mechanism and plate cam mechanism, less because moving apart from the traverse of motion, frequency is lower, Zhe Liangzhong mechanism both can meet the characteristics of motion, do not produce again impact, but all there is the problem of processing difficulties and wearing and tearing in cylindrical cam and plate cam slideway.
