Description

Gear rib transfer longan jacquard machine

The invention relates to a gear rib-transfer longan jacquard machine, in particular to a circular knitting machine for producing rib jacquard fabrics.

A ribbed loom is composed of two needles, so its ability to change is naturally much larger than that of a single-needle plain weave, and it can provide a variety of fabrics. The so-called Jacquard Knitting (Jacquard Knitting) It is to install a needle selection mechanism at the pin of the cylinder needle and plate needle of the knitting machine, or at the end of the sinker, so that it can selectively push up the knitting needle or push out the sinker, so as to produce a cloth surface There are colorful (composed of different colored yarns), shrunken, open-hole, and terry patterned fabrics. And this kind of knitting method that uses the needle selection mechanism to select the knitting needle or sinker is called jacquard knitting. The patterned fabric produced in this way is just called jacquard fabric, and in the traditional technology, a needle selection mechanism is equipped on the rib loom to form a rib jacquard loom.

In the traditional ribbed jacquard fabric, the jacquard fabric with transfer structure or longan structure is produced by a transfer knitting needle and Ha Fu needle (TRTNJ) respectively, and the aforementioned transfer knitting needle and Ha Fu needle are in the traditional The rib jacquard looms cannot be configured on the same rib jacquard machine at the same time, that is to say, the loop-transfer needles and the hafu needles are respectively configured on different rib jacquard machines. Therefore, a rib jacquard machine that can weave a transfer structure will not be able to produce a longan structure on the fabric that is produced at the same time. On the contrary, a rib jacquard machine that can weave a longan structure cannot weave a transfer structure. Therefore, it can be known that it is impossible for the transfer stitch and the longan stitch to appear on the same fabric at the same time, so that the variability of the jacquard fabric cannot be increased. This is a point that needs to be broken through in the traditional technology.

On the other hand, the structure of the transfer knitting needles mentioned above is not the same as that of the Hafu needles, so if a rib jacquard machine equipped with transfer knitting needles wants to be changed into a rib jacquard machine equipped with Hafu needles, except To remove all the original knitting needles, the sliders used to move the knitting needles should also be replaced with the sliders used to move the knitting needles. Or for the user of a group of loop-transfer knitting needles, it is quite a burden and inconvenient in terms of equipment cost and improvement of changing ability.

Therefore, the main purpose of the present invention is to provide a rib jacquard machine that can be equipped with the aforementioned loop-transfer needles and Harbin needles at the same time, so that the same rib jacquard machine can weave the loop-transfer structure on the same piece of fabric. and longan organization.

Another object of the present invention is to improve the changing ability of the rib jacquard machine. Needle or Hafu needle, cooperate with the action of latch needle, and then weave a kind of rib jacquard fabric with various patterns.

Another object of the present invention is to provide a multifunctional rib jacquard machine with various functions, which can weave rib fabric, Rib jacquard fabric, longan jacquard fabric, transfer jacquard fabric, ribbed longan transfer jacquard fabric and longan jacquard fabric that can produce longan weave in one side or two sides, so users don't need to buy many knitting machines Rib longan transfer jacquard obtains many different functions on the knitting machine.

Before explaining the structure and embodiments of the present invention, the stitching method and fabric structure of the fabric produced by the knitting machine will be described first, so that the fabric structure of the present invention can be more easily understood later.

First, please refer to Figure 1. The latch needle in the circular knitting machine is the main element used to weave the fabric. Through the reciprocating needle-out and needle-retracting action of the latch needle, the yarn can be hooked and gradually formed into a continuous yarn ring. fabric, and this action is called loop-making. As for the ring-making motion of the latch needle, as shown in Figure 1, it is a continuous circular action from left to right. As shown in the leftmost one in Fig. 1, the knitting needle 1 rises, and the old yarn ring 10 will press the latch 11, and slide down to the tip of the latch 11 along the inside of the latch 11. Continue to look at the picture on the right, when the knitting needle 1 continues to rise out of the needle to the highest point, the old yarn loop 10 slides down on the needle bar 12; continue to look at the right picture, the knitting needle 1 starts to descend and close the needle, and the old yarn loop 10 starts to go up at the same time At this moment, the yarn feed port 13 guides the new yarn 14 to the open needle hook 15; look at the right figure again, the knitting needle 1 continues to fall, the old yarn loop 10 pushes the needle latch 11, and along the needle latch The outer side of 11 slides up, and the new yarn 14 that is dialed into the needle hook 15 by the closing latch 11 will be pulled down for the knitting needle 11; The old yarn loop 10 breaks away from the needle head and enters the fabric structure 16. The aforementioned new yarn forms a loop 17 in the needle hook 15, replacing the original old yarn loop 10. So far, a loop-making cycle has been completed. Once the knitting needle 1 rises again When the needle is released, another loop-making movement starts again, and a fabric can be woven into such a continuous repeating cycle.

In addition, by controlling the needle-out position of the aforementioned knitting needle 1, the resulting fabric structure can be changed, thereby achieving the effect of producing unevenness or patterns. Generally, there are three kinds of needle-out changes of the knitting needle 1, and Figure 2 shows the normal ones. Needle exit position. At this time, the knitting needle 1 will completely exit the needle to the highest position, and the knitting function of feeding in new yarn and removing the old yarn loop is the same as the loop-making effect mentioned above, forming a regular knitting stitch. The woven yarn loop 2 will be uninterruptedly connected with the yarn loops 20, 20' generated before and after as shown in Figure 2.3.

If the needle exit height of knitting needle 1 is not enough, the highest can only reach the hanging needle position in Figure 2.1, and the yarn hanging effect will occur: the new yarn is absorbed but the old yarn ring is not removed, forming a hanging needle as shown in Figure 2.3 method and generate a hanging ring 21.

If the knitting needle 1 does not exit at all, or the exit height is insufficient, it can only reach the empty needle position in Figure 2.2, and it will produce an empty needle effect that does not eat new yarn or remove the old yarn loop, forming a situation as shown in Figure 2.4 The empty needle tissue 22 shown. Therefore, it can be seen from the above description that different needle exit positions will generate different fabric structures. When the same fabric weave appears continuously in another main weave, it will make the fabric produce pattern effect. Another thing to add is that the yarn ring 2 in Figure 2.3 is composed of two parts: the needle ring and the sinker ring. The so-called needle ring is the downward bending part of the yarn ring, and the sinker ring is the The part that curves upwards.

Please continue to refer to Fig. 3 and Fig. 5, wherein Fig. 3 shows the structure of the longan tissue generated by the present invention, and the most obvious and well-known difference from the transfer tissue in Fig. 5 is that the longan tissue has a larger aperture , the transfer structure is slightly smaller, so the pattern effect on the rib jacquard fabric is not the same.

The generation principle of the longan weave mentioned above is mainly to use a kind of Hafu needle (see Fig. 6) to move 1 or 2 sinking rings in the fabric weave to the yarn ring of the next or next weaving segment, so that An eyelet is formed on the cloth. The longan tissue shown in Figure 3 is the open-pore structure generated in this way. In Figure 3, the two weaving sections 3 and 4, and the two sinking rings between the two needles 2 and 3 have been lifted to the fifth section. On the two yarn rings 2 and 3, the connection between the 2 and 3 needles is lost. As long as a slight pulling force is applied from the left and right, an opening will be formed at this part.

And the structure of Kazakhstan needle 3, as shown in Figure 6, comprises two symmetrical metal flakes, left and right, and these two metal flakes merge into a structure with a hole 30 formed therebetween, and the front end has a section facing outwards. The protruding nose 31 in the needle direction is followed by a raised shoulder 32 at the rear edge of the nose 31, and this shoulder 32 maintains a drop relationship with the upper edge surface of the aforementioned nose 31, wherein the nose 31 The effect is to obtain the sinker ring 23 in the aforementioned Fig. 3, and the shoulder 32 is then used to hang the opened yarn ring 24 (see Fig. 3), as for the eyelet 30, its function is to open the aforementioned yarn ring 24 for supplying Knitting needle stretches into hook and gets the sinking ring 25 as shown in Figure 3.

For the longan generation operation of Ha Fuzhen 3, please refer to Figure 4, the sequence is:

1. As shown in Figure 4, the Hafu needle 3 stops, and the first yarn port introduces the yarn between the protruding plate needle 4 and the cylinder needle 5 to form a normal knitting segment.

2. As shown in Figure 4.1, the Hafu needle 3 is pushed out to the action position (approximately as the above-mentioned position for hanging the needle), and the 2nd and 3rd two yarn feeding ports continuously introduce the two yarns 26, 27 (see Figure 3) into the aforementioned Between the plate needle 4 and the tube needle 5, and simultaneously the two yarns 26, 27 are wound around the protruding Hafu needle nose 31. When the knitting needles 50, 51 are withdrawn to form two knitting segments, they are positioned at The sinking ring 23 between the 2nd and 3rd two needles 50, 51 can't descend with the needle because it hangs around the nose 31 of the needle, so the rod 3 is selected.

3. As shown in Figure 4.2, the Hafu needle 3 that has obtained the sinking ring 23 continues to extend out to the position of the needle, and with the widening of the metal sheets on both sides of the eye hole 30, the sinking ring 23 is gradually expanded, and the open The sinker ring 23 is suspended from the left and right shoulders 32, 32'.

4. As shown in Figure 4.3, the cylinder needles 50 and 51 go out to the full needle position, and go through the aforementioned eyelet 30 and the sinking ring 23 of the switch at the same time, so that the old yarn ring and the two hanging sinking rings 23 in the needle , all falling on the needle bar.

When the 4th yarn feeding port introduces the yarn 28 (see Fig. 3 ) into the open needle hook (52, 52 '), then the needles 3 and the needles 50, 51 are all retracted. In the process, the closed noses 31, 31' will be opened by the two cylinder needles 50, 51 in the eyelets 30, and the two sinking rings 23, 23' suspended thereon are also the two weaving needles. Pins 50, 51 are made. When the knitting needles 50, 51 descend to an appropriate level, these two sinking rings 23, 23 are to be looped off simultaneously with the old yarn loops 29, 29 ′ (seeing Fig. 3 ) of the knitting needles, and complete the formation process of a longan tissue. In the above-mentioned example, two symmetrical metal sheets are used for the needle 3 of Harbin, so the longan produced will have the width of two needles 50,51. Similarly, if only one metal sheet is used, and another metal sheet with a curved nose 31 and shoulder 32 is replaced with another straightened metal sheet of the same shape, the resulting longan will only be wide enough for one lower Needle 50 or 51 penetrates, and the aperture of this kind of longan tissue will be less. According to this transformation, we will be able to generate longan weaves of different sizes. With the ability of double-sided knitting with rib knitting machines, we can also generate longan weaves of different sizes on one or both sides of rib jacquard fabrics.

As for the stitch transfer generating operation of the stitch transfer knitting needle 6 (see FIG. 7 ), it is the same as the aforementioned Hafu needle 3, and only briefly described here. As can be seen in the figure, the front edge of the transfer knitting needle 6 has a needle latch 60 and a needle hook 61. When the transfer operation is not performed, the normal knitting operation is carried out just like the general latch needle as shown in the figure. A protruding shoulder 63 protrudes immediately adjacent to the rear edge of the needle bar 62 of the latch needle, and this protruding shoulder 63 is used for hanging the opened yarn loop 64 (see FIG. 5 ). There is a strut 66 parallel to the needle bar 62 on the side adjacent to the shoulder 63. The front edge of this strut 66 is normally close to the needle bar 62 and extends backward with a gradually opened relationship, and is connected with the needle bar. A transfer hole 65 is formed between 62. The strut 66 is used to stretch the yarn loops 64 of different knitting segments. The difference between it and the aforementioned Hafu needle 3 is that it can only stretch the yarn loops of one needle, and the cylinder needle passing through the transfer hole 65 There is only one, so the loop-transfer tissue generated by the loop-transfer knitting needle 6 will be slightly smaller than the longan tissue.

The present invention still needs to coordinate other structures in implementation, now make an explanation with reference to Fig. 8,9.

The above-mentioned knitting needles 3 and knitting needles 6 are arranged on the cylinder 7 of the circular knitting machine, and the knitting needles 3, which are made of two metal sheets, also occupy only one needle slot like the knitting needles 6. space, as for the interval or arrangement relationship, it can be arranged arbitrarily according to the position of the desired opening pattern.

The needle-out/needle closing operation of the Hafu needle 3 and the transfer knitting needle 6 is driven by two sliders 70, 70' that surround the lower edge of the needle cylinder 7 side by side. The operating strokes of the knitting needles 6 are not the same, so the slide rails 71, 71' on the correspondingly driven slide blocks 70, 70' are not the same. Moreover, the above-mentioned slide rails 71, 71' correspondingly driving the above-mentioned knitting needles 3 and knitting needles 6 respectively have two slide rails 710, 711 and 710', 711' which are mutually up and down. The rails 710, 710' are driving slide rails for normal knitting strokes. When the aforementioned connecting rods 3 and knitting needles 6 are driven by the lower slide rails 710, 710', they do not perform longan or stitch transfer operations.

On the contrary, when the above-mentioned knitting needles 3 and 6 enter the upper slide rails 711, 711', they will be driven to perform longan or stitch transfer operations. And after completing a generation operation of longan or ring transfer, the protrusions 33, 67 of the above-mentioned hafu needle 3 and knitting needle 6 will fall back to the lower floor from the intersection of the upper and lower slide rails 710, 710', 711, 711' The slide rails 710, 711 carry out normal knitting operations.

And above-mentioned knitting needle 3 and knitting needle 6 enter the slide rail 711,711 ' that is positioned at upper layer at any time, then be controlled by a needle selection mechanism and carry out. This needle selection mechanism includes an inclined flower wheel 8 and a needle extension push rod 80, and the needle extension push rod 80 is normally at a low position. When the longan or loop transfer operation is to be performed, the flower wheel 8 will push the needle extension push rod 80 up, and use the needle extension push rod 80 to push the corresponding Hafu needle 3 or loop transfer knitting needle 6 into the upper slide rail 711 , 711′. Therefore, along with the slide block 70, 70 ′ that the cylinder 7 operates, the relative Hafu needle 3 or the knitting needle 6 is driven to perform longan or stitch transfer operation.

Of course, as mentioned above, the rib jacquard machine includes two tissue needles (latch needles), one of which is a cylinder needle arranged on the needle cylinder 7, and the other group is arranged on the horizontal needle plate (see Figure 9) The plate needle, through the normal knitting operation of the cylinder needle and the plate needle, can produce a plain weaving rib fabric that generally does not have a pattern or opening structure. In addition to being equipped with the sliders 70, 70' for driving the above-mentioned knitting needles 3 and knitting needles 6, the present invention is also equipped with a slider 72 for driving general knitting needles. Therefore, at most, the needle cylinder 7 of the present invention can be equipped with the knitting needle 3 , the transfer needle 6 , the cylinder needle and the sliders 70 , 70 ′, 72 correspondingly driving the above three. As for the plate needles arranged on the needle plate, there are correspondingly driven slide blocks 9 (see FIG. 9 ) to drive them in the same way.

As a supplementary note, the Hafu needle 3 in Fig. 4 is taken as an illustration example when it is arranged on a horizontal needle plate. Although the position of the Hafu needle 3 arranged on the needle cylinder 7 is different from that of the present invention, it does not affect its manufacturing of ribs. The function of jacquard fabric.

Based on the above content, the present invention is not only different from the traditional technology in terms of knitting changes, but also its overall structure is a brand-new creation, which can generate longan, transfer ring and other open-hole structures on the same fabric, enriching the Types of ribbed jacquard fabrics.
