Problems solved by technology

[0004] The tricot warp knitting machine has the characteristics of high speed, but it cannot use more bars, so the jacquard effect is relatively single and simple, not flexible enough, and it is difficult to form a variety of jacquard effects; in addition, the tricot pulling structure makes the tricot The tension of the groove needle is large, and the lateral movement of the guide needle cannot be too large; these greatly limit the application of the tricot machine, and there is no tricot machine with jacquard on the market for weaving jacquard fabrics
Raschel warp knitting machine although the knitting needle force is small, but the fabric density is small, the resulting fabric is not thick enough

example 1

[0043] Example 1: see Figure 5 , when the traverse chain goes from 5 to 4, the jacquard guide needle pushes one stitch to the right before the groove needle, so that the yarn is not hooked into the needle hook, the yarn floats out, and no loop is formed. When the traversing chain block goes from 4 to 0, at the needle back of the groove needle, the jacquard guide needle recovers one stitch to the left.

[0044] In the next row, when the traverse chain block goes from 0 to 1 into a coil.

[0045] At this time, the jacquard pitch is 1 stitch.

[0046] Further, when the jacquard guide needle moves leftward, the jacquard guide needle pushes one stitch to the right in front of the groove needle, so that the yarn is not hooked into the needle hook, and the yarn floats out without forming a loop ; And in the next row, when the jacquard guide needle traverses to the left before the end, the jacquard guide needle recovers one stitch to the left, so that the yarn is not hooked into the ...

example 2

[0047] Example 2: see Figure 6 , when the traverse chain goes from 5 to 4, the jacquard guide needle pushes one stitch to the right before the groove needle, so that the yarn is not hooked into the needle hook, the yarn floats out, and no loop is formed.

[0048] In the next row, when the traversing chain block goes from 1 to 0, the jacquard guide needle recovers one needle to the left, so that the yarn is not hooked into the needle hook, the yarn floats out, and no loop is formed.

[0049] At this time, the jacquard pitch is 0 stitches.

example 3

[0050] Example 3: see Figure 7 , when the traversing chain moves from 1 to 5, the Jacquard yarn guide needle pushes one stitch on the back of the groove needle to the right;

[0051] In the next row, when the traversing chain block goes from 4 to 0, at the needle back of the groove needle, the jacquard guide needle recovers one needle to the left;

[0052] At this time, the jacquard pitch is 6 stitches, which is one stitch longer than the original jacquard pitch.

Abstract

The invention relates to a tricot jacquard warp knitting machine with a jacquard mechanism and a method of adjusting a jacquard stitch length. The machine comprises a frame, a coiling mechanism, a yarn passing mechanism, a pulling mechanism, a creel and a pan head; the coiling mechanism comprises a slotted needle bed, a needle core bed, a decoiling settlement sheet, at least two working line jacquard combs and at least two working line ground combs; the ground combs are arranged behind the jacquard combs; a jacquard comb yarn on the jacquard combs is led out from the creel and passes through the yarn passing mechanism; a ground comb yarn on the ground combs is lead out by the pan head and passed through the yarn passing mechanism. The machine and the method can effectively integrate the jacquard mechanism and a jacquard process into a tricot warp knitting machine so that a thick woven fabric with patterns can be quickly woven; the machine and the method are suitable for decoration, home textile and the like.

Description

technical field [0001] The invention relates to the field of warp knitting machines, in particular to a tricot jacquard warp knitting machine with jacquard and a method for adjusting jacquard pitch. Background technique [0002] Jacquard fabric is a pattern that is formed by changing the warp and weft weave of the fabric during weaving. Jacquard is usually realized by using the jacquard yarn guide end offset action, so that the jacquard yarn moving laterally changes on the woven ground structure to form a pattern. Jacquard needles use two rows as a unit, and one row can only complete one offset on the back of the needle. When the jacquard yarn guide needle is not jacquard, the partial inlay of two gauges is made to form a thin weave; when the jacquard yarn guide needle is blocked, the weft inlay of one gauge is made, and the jacquard yarn shrinks and winds on the longitudinal knitting chain Mesh is formed; when the jacquard yarn guide needle is moved forward by one pitch, ...
