Abstract
The invention discloses an interlacing mechanism of a mixed order fourier pitch curve non-circular gear reeling machine. Power is input by a main shaft, a driving sprocket, a worm and a driving bevel gear wheel are fixed on the main shaft, and interlacing mechanisms with same structures are symmetrically arranged on two sides of the main shaft. A driving first-order fourier pitch curve non-circular gear is meshed with a driven second-order fourier pitch curve non-circular gear, the driven second-order fourier pitch curve non-circular gear and a crank are fixed on a same shaft, and an interlacing rod is driven by a connecting rod to do reciprocating interlacing movement. One end of a fork-shaped oscillating bar is contacted with a master cam and an auxiliary cam in a conjugate cam through two rollers, the other end of the fork-shaped oscillating bar is fixedly connected with a gear case, and the other end of the fork-shaped oscillating bar is sleeved on a fourth shaft in an empty mode to drive the gear case to produce reciprocating swing. The interlacing mechanism enables stroke movement to be stable, an interlacing rod has periodic changes at a starting position and a stopping position in a shifting movement, and the defect that a silk yarn bypasses a small device to be higher in a left side and a right side due to the fact that a limiting position and a right limiting position of a stroke movement are low in speed.
Description
Technical field
The present invention relates to a kind of reeling machine traverse mechanism, be specifically related to a kind of exponent number Fourier pitch curve non-circular gear reeling machine traverse mechanism that mixes.
Background technology
The effect of traverse mechanism be make to be wound in little
on strand form 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, rolls up in little
even the function on the overlapping more limit of also not collapsing of the strand on limit.Traverse mechanism is finally carried out member---and the motion of cross winding bar is stroke motion and moves synthesizing 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.
