Referring to fig. 6, the principle and advantages of the guide bar electronic swing device and the looping mechanism of the warp knitting machine of this embodiment are as follows:
unlike the prior art, the previous cam transmission mode of the spacing yarn guide bar 15 is changed, the previous swing period of the spacing yarn guide bar 15 is the same as the swing period of the face yarn guide bar 6 (as shown on the left side of fig. 6, the swing period of the spacing yarn guide bar is that of the face yarn guide bar=1:1), during the working process, the main shaft rotates one circle (360 °), the face yarn guide bar 6 completes one swing period movement, the first A-face base fabric row is woven once in a circle, and the spacing yarn guide bar 15 is also looped once on the first row of the A-face base fabric; the spindle rotates a second turn (720 °), the a-side guide bar 6 completes a second periodic movement, and then a second a-side base fabric row is knitted once by looping, and the spacing guide bar 15 is also looped a second time on the second row of a-side base fabric. Due to the symmetry of the double needle bed 19, the swinging and looping action time of the guide bar on the B surface is different from that of the guide bar on the A surface by half a period, and along with the swinging of the guide bar 15 for spacer yarns, the spacer yarns do Z-shaped reciprocating swinging and looping on the row of the base fabric on the A surface and the row of the base fabric on the B surface, so that the embryo cloth is woven. Even if the space yarn guide bar 15 swings by synchronous wheels, gears and the like with different tooth ratios to finish swinging with different periods from the face yarn guide bar 6, the adjusting method has the advantages of complex disassembly and assembly and replacement, single transmission speed ratio and lower precision.
The spacing bar 15 wobble period is now electronically controlled such that the spacing bar 15 wobble period is different from the face bar 6 wobble period, taking for example 3 times the face bar 6 wobble period as the spacing bar 15 wobble period (as shown on the right side of fig. 6, spacing bar wobble period: face bar wobble period = 3: 1). When the main shaft rotates for one circle, the A-side yarn guide bar 6 completes a swinging period, a first A-side base fabric row is knitted once in a looping way, and at the moment, the first looping is also completed on the A-side base fabric row by electronically controlling the spacer yarn; when the main shaft rotates for the second circle and the third circle, the A-side yarn guide bar 6 finishes the second swing period and the third swing period, the second and the third A-side base fabric courses are knitted twice in a looping way, the interval yarn guide bar 15 swings to the other side during the second swing period, the interval yarn guide bar 15 loops on the B-side base fabric once and swings backwards, and the interval yarn guide bar 15 does not reach the looping position of the A-side courses due to the 3-time cycle ratio; when the spindle rotates for the fourth turn, the a-side guide bar 6 completes one swing cycle again, completes the fourth looping, weaves the fourth a-side base fabric course, and at this time, the spacer guide bar 15 just swings to the fourth course position of the a-side base fabric to complete one looping. The spacer yarns are looped on the a side (or B side) of the base fabric every 2 courses. Because the invention adopts electronic servo control, the ratio of the swing period of the spacing yarn guide bar 15 to the swing period of the face yarn guide bar 6 is adjustable, the looping interval of the spacing yarn on the base fabric transverse row is also adjustable, and the invention meets diversified looping processes.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
