Abstract
The utility model discloses a first-stage and second-stage deformed elliptical gear reeling machine cross winding mechanism. Power is input by a main shaft, a drive chain wheel, a worm and a drive cone gear are fixed on the main shaft in sequence, and the cross winding mechanisms of the same structure are symmetrically installed at two sides of the main shaft. A drive first-stage deformed elliptical gear is meshed with a driven second-stage deformed elliptical gear, the driven second-stage deformed elliptical gear and a crank are fixed on the same shaft, and a cross winding rod is driven by a connection rod to make reciprocating cross winding movements. One end of a fork-shaped oscillating rod contacts a primary cam and a secondary cam of a conjugate cam through two running pulleys, the other end of the fork-shaped oscillating rod is fixedly connected with a gear box and is sleeved outside a fourth shaft in a hollow mode, and therefore the gear box is driven to swing back and forth. According to the first-stage and second-stage deformed elliptical gear reeling machine cross winding mechanism, the travel movement enables speed to be more stable, shift movement enables the cross winding rod to generate periodical change in a start position and a finish position in travel movement, and the defect that the left side and the right side are high when silk yarns are winded to the back of a small part due to the fact that a left limiting position and a right limiting position in travel movement are small in speed is overcome.
Description
Technical field
The utility model relates to a kind of reeling machine traverse mechanism, is specifically related to a kind of single order and second order sex change elliptic gear reeling machine traverse mechanism.
Background technology
The effect of traverse mechanism is to make the strand that is wound on little form netted silk sheet, it affect a sheet be shaped with quality, the rereeling of dry mass move back the difficulty or ease of separating and coiling loading amount how much etc.Traverse mechanism must possess the strand that makes the adjacent two layers filature and not overlap and batch equably, and easy change when strand cuts off is even roll up in the function on the overlapping more limit of also not collapsing of the strand on little limit.Traverse mechanism finally carry out member----the motion of cross winding bar is a stroke motion and move synthetic apart from motion.
At present; Traverse mechanism on the reeling machine of selling on the market at home; Its stroke motion is mainly realized through three kinds of mechanisms: cylindrical cam mechanism, and the type mechanism can realize the at the uniform velocity reciprocating motion of cross winding bar through changing the cylindrical cam profile, but when switching-over, can produce very big impact; 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, and recessed in the middle of the silk sheet 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 combined mechanism design of cyclic train and the crank block of change journey helps increasing the overlapping cycle, improves the surperficial flatness of silk sheet, but under constant condition of cycle, when traverse reduced, winding angle also reduced.It moves apart from motion is main and realizes through two kinds of mechanisms: cylindrical cam mechanism and plate cam mechanism; Less because of moving apart from the traverse of motion; Frequency is lower; These two kinds of mechanisms both can satisfy the characteristics of motion, did not produce impact again, but cylindrical cam and plate cam slideway all exist processing difficulties and wear problems.
Summary of the invention
In order to overcome the problem that exists in the background technology, the purpose of the utility model is to provide a kind of single order and second order sex change elliptic gear reeling machine traverse mechanism.
