Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machines, in particular to the technical field of high-efficiency circular knitting machines for sweater fabrics. Background Art

[0002] 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).

[0003] A flat knitting machine, also known as a flat knitting machine, is a machine that uses reciprocating motion during the fabric weaving process. Common types include iron flat knitting machines, computer flat knitting machines, and household knitting machines. The main feature of a flat knitting machine is that its needle bed and triangle device can move left and right to achieve the weaving of knitted fabrics (flat knitting machines play an important role in the production of knitted fabrics such as sweater cloth).

[0004] However, although flat knitting machines can produce sweater cloth, they have the problem of low production capacity (one machine can usually only produce 20 kilograms of sweater cloth a day and can only make 24 to 36 garment pieces); the unique structure of the transfer jacquard fabric enables it to have a higher fabric processing efficiency; therefore, how to make the transfer jacquard fabric efficiently produce sweater cloth needs to be solved urgently. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to provide a high-efficiency sweater fabric circular knitting machine, which can efficiently and stably produce sweater fabrics, and the daily output is much higher than that of a flat knitting machine.

[0006] To achieve the above-mentioned purpose, the present invention proposes a high-efficiency circular knitting machine for sweater cloth, comprising an upper transfer circle jacquard machine heart, an upper triangle, a needle plate, a bead plate, a knitting needle, a jacquard needle cylinder, a lower transfer circle needle, a lower triangle and a lower transfer circle jacquard machine heart, wherein the upper triangle and the lower triangle are respectively installed on the upper transfer circle jacquard machine heart and the lower transfer circle 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, the knitting needle is arranged between the upper triangle and the needle plate and can be guided by the upper triangle to move laterally along the upper needle groove located on the surface of the needle plate, the lower transfer circle needle is 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, and the knitting needle and the lower transfer circle needle both adopt a needle pitch of 10 to 14 needles.

[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 12 needles.

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

[0012] Preferably, the machine speed is controlled at 12 revolutions.

[0013] Preferably, a circle expansion piece is provided on the lower moving circle needle.

[0014] Beneficial effects of the present invention: 1) When the transfer jacquard circular knitting machine adopts a fine needle gauge design, it can be applied to the fabric manufacturing of clothing such as T-shirts, and the elasticity of the woven products is greater than that of flat knitting fabrics (more comfortable to wear), and when the coarse needle gauge design is adopted, it can weave sweaters similar to those woven by flat knitting fabrics; based on this, the present invention adopts thicker upper and lower needles (that is, the knitting needles and the lower transfer needles both adopt a needle gauge of 10 to 14 needles, such as a needle gauge of 12 needles), which can achieve a needle gauge of 90 threads, so that the machine has the ability to weave very thick yarns (such as 14 wool or imitation rabbit hair yarns), and finally realizes the weaving of sweater fabrics; 2) The present invention controls the machine speed to 10 to 14 revolutions (e.g., 12 revolutions), so that the production capacity of one transfer jacquard circular knitting machine can be equivalent to that of 10 flat knitting machines (when using sweater yarns such as imitation rabbit plush yarn to knit sweater fabrics, a single machine can achieve a daily output of more than 300 kilograms), thereby greatly improving the problem of insufficient production capacity of sweater fabrics of flat knitting machines; 3) By adding a circle expansion piece at the lower needle, the lower triangle can use the triangle change track to make the lower needle move up and down at different routes, thereby weaving holes that were originally only possible on a flat knitting machine.

[0015] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
