Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machines, in particular to the technical field of low-elastic imitation woven jacquard circular knitting machines. Background Art

[0002] A shuttle loom is a traditional loom that uses a shuttle to introduce weft yarn. The shuttle can be driven by the striking of the shuttle throwing mechanism to insert the weft to complete the weaving process. The main structure of the shuttle loom includes a main machine, a weaving frame, a shuttle and a power system. Among them, the main machine is the core part of the shuttle loom, which includes a shuttle throwing device, a shuttle track and a shuttle driving device, etc. The weaving frame is used to support the cloth and keep it flat during the weaving process. The shuttle is used to cross-weave yarns, and the power system can provide power for the shuttle loom and usually uses an electric or diesel engine.

[0003] Loop transfer jacquard fabric is a unique jacquard fabric with a three-dimensional and artistic feel woven by a circular knitting machine. It is widely used as T-shirt fabric. Specifically, the circular knitting machine can shift the coils and form patterns with different densities by changing the position of the knitting needles (during the weaving process, the needles will first cover one or more coils and then move the positions of these coils to create various concave and convex or vertical and horizontal twisting effects).

[0004] The jacquard transfer circular knitting machine can produce many fabrics with similar styles to those of the flat knitting machine, but the circular knitting machine fabrics usually have good elasticity; that is to say, the jacquard transfer circular knitting machine cannot produce fabrics with visible horizontal floating thread texture effects like the shuttle loom (it cannot make the yarn float out and hide like shuttle weaving); this leads to the factory having to purchase additional shuttle looms to weave low-elasticity fabrics when it only has the jacquard transfer circular knitting machine. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose a low-elastic imitation woven jacquard transfer jacquard machine, which can use a yarn guide to feed yarn that does not participate in weaving around the machine in the weft direction, so that the machine can produce woven fabrics with rough style and low elasticity characteristics like a shuttle loom (rather than only being able to produce circular machine fabrics with good elasticity), greatly broadening the application scenarios of the machine.

[0006] To achieve the above-mentioned purpose, the present invention proposes a low-elastic imitation shuttle woven jacquard transfer jacquard machine, comprising an upper transfer jacquard machine heart, an upper triangle, a needle plate, a bead plate, a yarn guide, a knitting needle, a jacquard needle cylinder, a lower transfer needle, a lower triangle and a lower transfer jacquard machine heart, wherein the upper triangle and the lower triangle are respectively installed on the upper transfer jacquard machine heart and the lower transfer jacquard machine heart, the needle plate is supported by the bead plate and fits with the upper triangle, the jacquard needle cylinder can rotate synchronously with the needle plate and fits with the lower triangle, and the The knitting needles are arranged between the upper triangle and the needle disk and can be guided by the upper triangle to move laterally along the upper needle groove located on the surface of the needle disk. The lower transfer needles are arranged between the jacquard needle cylinder and the lower triangle and can be guided by the lower triangle to move vertically along the lower needle groove located on the surface of the jacquard needle cylinder. The yarn guide is installed on the upper transfer jacquard machine heart and can feed the yarn into the interlayer located between the surface layer and the bottom layer of the fabric. The yarn spitted out by the yarn guide can be exposed by transferring part of the front loop through the jacquard processing.

[0007] Preferably, it further comprises a connecting needle and a jacquard piece, wherein the lower transfer loop needle, the connecting needle and the jacquard piece are detachably connected in sequence from top to bottom, and the knitting needle and the lower transfer loop needle are matched with each other through an upper hook and a lower hook located at adjacent ends.

[0008] Preferably, an upper convex portion is provided on the side of the knitting needle facing the upper triangle, and an upper guide rail is provided on the upper triangle for the upper convex portion to slide into and guide the knitting needle to move laterally.

[0009] Preferably, the lower moving needle and the connecting needle are respectively provided with a first lower convex portion and a second lower convex portion on the side facing the lower triangle, and the lower triangle is respectively provided with a first lower guide rail and a second lower guide rail for the first lower convex portion and the second lower convex portion to slide into and guide the lower moving needle and the connecting needle to move vertically.

[0010] Preferably, the knitting needles and the lower transfer needles both have a needle pitch of 10 to 14 needles.

[0011] Preferably, the machine speed is controlled at 10 to 14 revolutions.

[0012] Preferably, the yarn guide allows the yarn to be fed behind the needles before the knitting needles and the lower transfer needles are removed to form long floating threads like shuttle weaving.

[0013] Preferably, the yarn guide feeds the yarn along the weft direction between the first loop formation and the second loop formation.

[0014] Beneficial effects of the present invention: 1) The present invention adds a yarn guide to feed the yarn between the first loop formation and the second loop formation (the yarn enters the interlayer located on the upper and lower surfaces of the fabric only along the weft direction without weaving), so that not only can long floating threads like woven fabrics be formed in the finished product, but also the user can choose whether to use jacquard processing on the yarn to transfer part of the front loops according to the needs (that is, the user can freely choose whether to expose the yarn according to the needs). The woven imitation woven loop transfer jacquard fabric has significantly lower elasticity than the traditional circular knitting fabric and has the characteristics of straight and thick fabric surface; 2) The present invention adopts thicker upper and lower needles (that is, the knitting needles and the lower transfer needles both adopt a needle length of 10 to 14 needles, such as a needle length of 12 needles), which can achieve a needle length of 90 needles, so that the machine has the ability to weave very thick yarns (such as 14 wool or imitation rabbit hair yarns), and finally weaves low-elastic and thick small fragrance style fabrics; 3) The present invention controls the machine speed to 10 to 14 revolutions (such as 12 revolutions), thereby greatly improving the production capacity of the transfer jacquard circular knitting machine (when knitting sweater yarns such as imitation rabbit plush yarns, a single machine can achieve a daily output of more than 300 kilograms).

The upper triangle 2 and the lower triangle 9 are respectively installed on the upper transfer jacquard machine heart 1 and the lower transfer jacquard machine heart 10. The needle plate 3 is supported by the bead plate 4 and fits with the upper triangle 2. The jacquard needle cylinder 7 can rotate synchronously with the needle plate 3 and fits with the lower triangle 9. The knitting needle 6 is arranged between the upper triangle 2 and the needle disk 3 and can be guided by the upper triangle 2 to move laterally along the upper needle groove located on the surface of the needle disk 3. The lower transfer needle 8 is arranged between the jacquard needle cylinder 7 and the lower triangle 9 and can be guided by the lower triangle 9 to move vertically along the lower needle groove located on the surface of the jacquard needle cylinder 7. The yarn guide 5 is installed on the upper transfer jacquard machine heart 1 and can feed the yarn into the interlayer between the surface layer and the bottom layer of the fabric. The yarn spitted out by the yarn guide 5 can be exposed by transferring part of the front loop through the jacquard processing.

[0019] It also includes a connecting needle 11 and a jacquard piece 12. The lower transfer needle 8, the connecting needle 11 and the jacquard piece 12 are detachably connected in sequence from top to bottom. The knitting needle 6 and the lower transfer needle 8 are matched with each other through the upper hook and the lower hook located at the adjacent ends.

[0020] An upper convex portion 61 is provided on the side of the knitting needle 6 facing the upper triangle 2 , and an upper guide rail 21 is provided on the upper triangle 2 for the upper convex portion 61 to slide into and guide the knitting needle 6 to move laterally.

[0021] The lower transfer needle 8 and the connecting needle 11 are respectively provided with a first lower protrusion 81 and a second lower protrusion 111 on the side facing the lower triangle 9, and the lower triangle 9 is respectively provided with a first lower guide rail 91 and a second lower guide rail 92 for the first lower protrusion 81 and the second lower protrusion 111 to slide into and guide the lower transfer needle 8 and the connecting needle 11 to move vertically.

[0022] The knitting needle 6 and the lower transfer needle 8 both adopt a needle length of 12 needles.

[0023] The machine speed is controlled at 12 rpm.

[0024] The yarn guide 5 feeds the yarn behind the needles 6 and the lower transfer needles 8 before the needles are removed to form long floating threads like shuttle weaving.

[0025] The yarn guide 5 feeds the yarn along the weft direction between the first loop formation and the second loop formation.

[0026] Working process of the present invention: During the period when the needle disk 3 and the jacquard needle cylinder 7 are driven to rotate synchronously, on the one hand, the upper cam 2 guides the knitting needle 6 to move horizontally through the upper guide rail 21 (the needle outlet position of the needle disk 33 is as shown in FIG. Figure 3On the other hand, the lower triangle 9 guides the lower transfer needle 8 and the receiving needle 11 to move vertically through the first lower guide rail 91 and the second lower guide rail 92 (the needle exit position of the jacquard needle cylinder 7 is shown in FIG. Figure 3 As shown in the n line), the knitting needle 6 and the lower transfer needle 8 complete the knitting work together.

[0027] In the above process, the yarn guide 5 can also feed the yarn (such as red 10S slub yarn) in the interlayer between the surface layer (such as the surface layer woven with low elastic yarn 150D extra black) and the bottom layer (such as the bottom layer woven with red 21S ring-spun yarn); in addition, the factory can choose whether to perform jacquard treatment on the yarn to transfer part of the front loop, so that the yarn is exposed or remains hidden; Figure 4 As shown, for the final imitation woven jacquard fabric, since the thick and thin slub yarns are just horizontally inside the fabric, the fabric has very low elasticity and can be used to make Chanel-style coats or long skirts and other clothing.

[0028] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
