Abstract
The invention discloses traverse mechanisms of a silk reeling machine and with mixed-order sine type non-circular gears. 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 sine type non-circular gear is meshed with a driven second-order degeneration sine type non-circular gear, the driven second-order degeneration sine type 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 mixing exponent number sinusoidal pattern non-circular 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 object of the present invention is to provide a kind of mixing exponent number sinusoidal pattern non-circular gear reeling machine traverse mechanism.
In order to achieve the above object, the technical scheme of the present invention's employing is:
Power of the present invention is imported by main shaft, is fixed with drive sprocket, worm screw and active bevel gear on the main shaft successively; Drive sprocket is passed to driven sprocket through chain with power, and driven sprocket all is fixed on first with the active roller gear, and initiatively roller gear is meshed driven cylindrical gear and little all being fixed on second with driven cylindrical gear; Worm and wheel is meshed, and worm gear is fixed on the 3rd; Initiatively bevel gear is meshed with left driven bevel gear and right driven bevel gear respectively, and left driven bevel gear is fixed on the end on the 4th on a left side, and right driven bevel gear is fixed on the end on the 4th on the right side; The main shaft both sides are identical left traverse mechanism and the right traverse mechanism of symmetrical mounting structure respectively, and the 3rd two ends, left the 4th the other end and right the 4th the other end extend into respectively in the left traverse mechanism and right traverse mechanism separately; The structure of described left traverse mechanism is: the 4th on a left side is supported on the left gear case; A left side initiatively single order sex change sinusoidal pattern non-circular gear is fixed on the other end on the 4th on the interior left side of left gear; A left side initiatively single order sex change sinusoidal pattern non-circular gear is meshed with left driven second order sex change sinusoidal pattern non-circular gear; The driven second order sex change sinusoidal pattern non-circular gear in a left side is fixed on left the 5th, and the 5th on a left side is supported on the left gear case; One end of left side crank is fixed on the 5th on a left side and extends on the outer end of left gear casing, and an end of left connecting rod and the other end of left crank are hinged, and an end of the other end of left connecting rod and left cross winding bar is hinged; The left conjugate cam of being made up of left main cam and left auxiliary cam is fixed on the 3rd; Left side conjugate cam, left fork-shaped fork and two sons that roll left that are fixed on the left fork-shaped fork are formed left conjugate cam mechanism; Left side fork-shaped fork is left conjugate cam mechanism driven member; One end of left side fork-shaped fork through two roll left son respectively with left conjugate cam in left main cam, left auxiliary cam contact, the other end of left fork-shaped fork connects firmly with the left gear case mutually, and sky is enclosed within on left the 4th.
When the center of rotation line of described left side active single order sex change sinusoidal pattern non-circular gear and left driven second order sex change sinusoidal pattern non-circular gear was in horizontal line, left cross winding bar also was on the same horizontal line.
The centre-to-centre spacing of described left side active single order sex change sinusoidal pattern non-circular gear and left driven second order sex change sinusoidal pattern non-circular gear is 50 ~ 60mm.
During work, the angle that swings up and down of described left gear case is 10 °, is that the angle that swings up and down of the axis of symmetry is 5 ° with the horizontal line.
The beneficial effect that the present invention has is:
The present invention adopts the combination of single order and second order sex change sinusoidal pattern non-circular gear and slider-crank mechanism to realize the stroke motion of traverse mechanism; Like this when second order sex change sinusoidal pattern non-circular gear rotates a week; Its rotating speed speed changes four times; Just with slide block reciprocating motion one-period slow fast change four times corresponding, thereby make in the cross winding bar reciprocating motion process longer constant speed is around arranged, and this slider-crank mechanism can be approximately centric slider-crank mechanism; There is not anxious returning in process and backhaul, and make speed more steady; Adopt conjugate cam driven gear casing to produce reciprocally swinging and realize moving of traverse mechanism apart from motion; It is little to wear and tear; Make all the time position of cross winding bar in stroke motion produce periodic variation, produce silk thread around arriving the higher shortcoming of little back the right and left thereby overcome because of stroke motion left and right sides two limit positions speed is little, the silk sheet thickness that forms like this is even, shaping is good; And the employing conjugate cam, easy to process.
