Description
Technical field
The present invention relates to a kind of reeling machine traverse mechanism, be specifically related to a kind of integrated oscillating type Pascal curve 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 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.
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 integrated oscillating type Pascal curve non-circular gear reeling machine traverse mechanism.
In order to achieve the above object, the technical solution used in the present invention is:
Power of the present invention is inputted by being arranged on the driven sprocket that main shaft is positioned on the outer one end of casing, and main shaft is equipped with successively worm screw and bevel gear initiatively in casing on one end; In casing, both sides are equipped with the second axle, the first axle and crank axle from bottom to up successively, and worm and wheel is meshed, and worm gear is fixed on the second axle; Initiatively bevel gear is meshed with driven bevel gear, driven bevel gear and initiatively single order Pascal curve non-circular gear are all fixed on the first axle, initiatively single order Pascal curve non-circular gear is meshed with driven second order conjugation Pascal curve non-circular gear, driven second order conjugation Pascal curve non-circular gear is fixed on crank axle, install respectively on crank axle one end of two rocking arms, and the other end difference kink of two rocking arms is on the first axle; One end of two cranks is separately fixed on the two ends that extend to the crank axle outside casing, and one end of two connecting rods is hinged with the other end of crank separately respectively, and the other end of two connecting rods is hinged with cross winding bar separately respectively; The conjugate cam being made up of main cam and auxiliary cam is fixed on the second axle, conjugate cam, fork-shaped fork and two rollers that are fixed on fork-shaped fork form conjugate cam mechanisms, fork-shaped fork is conjugate cam mechanism driven member, one end of fork-shaped fork contacts with main cam, auxiliary cam in conjugate cam respectively by two rollers, and the other end of fork-shaped fork is connected mutually with rocking arm; Casing all has chute at the overhanging two ends of crank axle place, and when work, crank axle is along with rocking arm swings in the chute on casing around the first axle.
Described rocking arm is in the time of vertical position, and the plane of cross winding bar and driven second order conjugation Pascal curve non-circular gear axle center composition is horizontal plane.
The beneficial effect that the present invention has is:
1) the present invention adopts the combination of integrated oscillating type Pascal curve non-circular gear and slider-crank mechanism to realize the stroke motion of traverse mechanism, in the time that driven second order conjugation Pascal curve non-circular gear rotates one week, its rotating speed speed changes four times, just with slide block reciprocating motion one-period slow fast change four times corresponding, thereby make there is longer constant speed around in cross winding bar reciprocating motion process; And the traditional implementation method of stroke motion is the roller gear that a pair of eccentric gear and a pair of gear ratio are 1:2, for example EB type traverse mechanism, the present invention is simple in structure by contrast.
2) the present invention adopts conjugate cam to drive rocking arm to produce reciprocally swinging and realizes moving apart from motion of traverse mechanism, the all the time position of cross winding bar in stroke motion produced periodically and change, produce silk thread because stroke motion left and right two limit positions speed is little around arriving the higher shortcoming of little rear the right and left thereby overcome; To realize by gear, edge cam and the return spring of few teeth difference and move apart from the traditional implementation method of motion, for example EB type traverse mechanism, the present invention is simple in structure, easy to process by contrast, and does not have relaxing of spring problem.
3) the each member of the present invention is included in same casing, and good sealing effect, and in the course of work, casing maintains static only has the correlated parts such as rocking arm of box house to swing, and dynamics is good; And HR2 type and EB type is that whole casing swings.
