Abstract
The invention discloses traverse mechanisms of a silk reeling machine and with a first-order degeneration eccentric-circle gear and a second-order conjugate non-circular gear. Power is input through a spindle, a driving sprocket, a worm and a driving bevel gear wheel are fixed on the spindle in sequence, and the traverse mechanisms with the same structure are symmetrically installed on two sides of the spindle. A driving first-order degeneration eccentric-circle gear is meshed with a driven second-order conjugate non-circular gear, the driven second-order conjugate non-circular gear and a crank are fixed on the same shaft, and a traverse rod is driven by a connection rod to perform reciprocating traverse movements. One end of a forked swinging rod is contacted with a main cam and an auxiliary cam in a conjugate cam through two rollers, and the other end of the forked swinging rod is fixedly connected with a gear box and is sleeved on a fourth shaft in an empty mode to drive a gear box body to perform reciprocating swing. The stroke movement of the traverse mechanisms enables the speed to be stable, and the shift movement enables the starting position and the finishing position of the traverse rod in the stroke movement to change periodically, so that the shortcoming that silk thread is wound at higher positions on the left side and the right side behind a 'yue' (a tool for holding the silk thread) due to low speed of the left limited position and the right limited position in the stroke movement is overcome.
Description
Technical field
The present invention relates to a kind of reeling machine traverse mechanism, be specifically related to a kind of single order sex change eccentric gear and second order conjugation non-circular gear reeling machine traverse mechanism.
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 when 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 change 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, when 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.
Summary of the invention
In order to overcome the problem existing in background technology, the object of the present invention is to provide a kind of single order sex change eccentric gear and second order conjugation non-circular gear reeling machine traverse mechanism.
