Description
Technical field
The present invention relates to the warp knitting machine parts, is a kind of oscillating motion mechanism of warp knitting machine knitting needle needle-bar.
Background technology
In the warp knitting machine braided fabric process, hooking up the yarn lopping by knitting needle is one of significant process that forms in fabric tissue, and for correct lopping, the motion of the general motion that requires to have knitting needle, sley bar and subsiding movement are worked in coordination and finished.The motion of sley bar is generally the swing around fixing point, when the sley bar number more after a little while, its quality and rotary inertia are less, inertia force that produces during swing and moment of inertia are less to the influence of complete machine rotating speed, when the sley bar number more for a long time, its quality and rotary inertia are bigger, if still swing, have bigger inertia force and moment of inertia, be unfavorable for that complete machine at a high speed, therefore, generally adopts sley bar motionless in this case, its swing is appended to the solution that knitting needle gets on, and the motion of knitting needle just becomes the compound motion that adds reciprocally swinging for original motion (generally be up and down reciprocatingly rectilinear motion).Because the motion of knitting needle is the synthetic of two motions, but is not the simple superposition of original two motions.According to technology, the reciprocally swinging of knitting needle go (by behind the machine to machine) and return (by before the machine to machine) two about 2:1 of process average velocity ratio, this ratio of different type of machines may be slightly different, but roughly more approaching with this value, claim also that in mechanism this ratio is advanceto returntime ratio.The transmission requirement of advanceto returntime ratio about 2, belong to bigger situation, in order to realize this motion requirement, the knitting needle swing mechanism that uses on the general warp knitting machine adopts cam mechanism, because cam mechanism is at a high speed unsuitable, limited the further raising of warp knitting machine speed, and cam mechanism processing and manufacturing difficulty, cost height.
Summary of the invention
The objective of the invention is to propose a kind of suiting runs up and can satisfy the knitting needle bed swinging mechanism of high-speed tricot machine that the bigger transmission of advanceto returntime ratio requires.
Technical conceive of the present invention is as follows:
The continuous rotation of main shaft is converted to the reciprocally swinging of knitting needle needle-bar, and simple approach is directly to use Planar Crank-and-rocker Mechanism, but its range speed ratio factor that can realize generally can not be too big, otherwise the minimum transmission angle of mechanism is too little, and transmission efficiency is low.Clearly, about 2, belong to bigger transmission for advanceto returntime ratio and require situation, can not select Planar Crank-and-rocker Mechanism for use.Select for use oscillating guidebar mechanism to realize big advanceto returntime ratio among the present invention, the lanar four rod mechanism of connecting again thereafter, be referred to as traverse and adjust quadric chain, long by the bar of adjusting this mechanism than making this motion of mechanism take-off lever pivot angle size satisfy the requirement of knitting needle needle-bar pendulum angle size.
For achieving the above object, the present invention takes following technical scheme:
The present invention has the main shaft that is in the warp knitting machine fuel tank, the needle-bar seat that is in the outer balance staff of warp knitting machine fuel tank and knitting needle needle-bar and support knitting needle needle-bar; Be fixed with needle-bar initiatively swing arm and the driven swing arm of needle-bar on the described balance staff, connect with the moving sets form between described needle-bar seat and the driven swing arm of needle-bar; Be fixed with eccentric wheel on the described main shaft, be connected with the guiding overcoat with the revolute pair form on the eccentric wheel, the side of main shaft is provided with the bearing pin that parallels, be fixed with guide post and side link on the bearing pin, described guiding puts outward and is provided with the guide post hole, guide post constitutes moving sets by the outer guide post hole that puts of leading with the guiding overcoat, and described guide post is connected with connecting rod with the revolute pair form, and connecting rod passes fuel tank and connects with the driven swing arm of described needle-bar with the revolute pair form.
Setting-up eccentricity wheel on the main shaft of this knitting needle bed swinging mechanism of high-speed tricot machine, the guiding overcoat is enclosed within that both relatively rotate the formation revolute pair on the eccentric wheel, constitute oscillating guidebar mechanism by eccentric wheel, eccentric wheel sleeve, guide post and frame, oscillating guidebar mechanism is elementary lanar four rod mechanism, by changing the long and frame length ratio of this elementary lanar four rod mechanism king-rod, will change its advanceto returntime ratio, promptly change eccentric eccentric throw and the ratio of the alignment of shafts, will change advanceto returntime ratio to the distance of guide post oscillation center.Equal the half of the alignment of shafts to the distance of guide post oscillation center when satisfying eccentric eccentric throw, its advanceto returntime ratio is 2.Constitute second level planar pivot four-bar mechanism by side link, connecting rod, needle-bar active swing arm and frame, its effect is that the pendulum angle size of guide post is adjusted to the pendulum angle size that needle-bar active swing arm needs, to satisfy the pendulum angle requirement of needle-bar.Connect with moving sets between knitting needle needle-bar and the driven swing arm of needle-bar, just can only relatively move between them, do not relatively rotate, so just guaranteed the swing size of knitting needle needle-bar and the swing equal and opposite in direction of the driven swing arm of needle-bar.
Characteristics of the present invention are:
1, integral body of the present invention is made up of the single-freedom planar linkage, compares with existing structure, need not driven by interior outer rim conjugate cam mechanism, suits to use on the high speed warp knitting machine.
2, the kinematic pair in the entire mechanism is a planar lower pair entirely, does not have higher pair, so processing and manufacturing is easy, has reduced manufacturing cost.
3, by changing in the swing guide post mechanism eccentric eccentric throw and the alignment of shafts to the ratio of two distances of guide post oscillation center, realize different big or small advanceto returntime ratios, the advanceto returntime ratio scope that such structure can realize is wide, more can adapt to different instructions for uses.
4, realize knitting needle needle-bar pendulum angle by follow-up planar pivot four-bar mechanism, the dimensions length relation that changes in the mechanism just can change knitting needle needle-bar pendulum angle, and is easy to adjust, wide accommodation.
