Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flat knitting machine, and specifically to a triangular layout structure of three-system flat knitting machine. BACKGROUND

[0002] The flat knitting machine is a double needle plate latch needle weft knitting machine, and its cam system is like a group of plane cams, the needle stitch of the needle can enter the channel of the cam, the cam system is moved to force the needle to make regular lifting movement in the needle groove, and through the action of the needle hook and the latch, the yarn can be knitted into a knitted fabric. During the lifting of the needle, the loop gradually exits the needle hook, the latch is opened, and the old loop is hung on the needle bar; during the descent of the needle, the needle hook hooks the newly laid yarn and pulls it to bend into a loop, and at the same time, the original loop is detached from the needle hook, and the new loop passes through the old loop to be connected in series with the old loop, and the loops knitted by the numerous needles are connected to form a knitted fabric.

[0003] The above-mentioned needle generally includes a hook needle (also called a main needle and a needle, without a needle butt) at the uppermost position for hooking the yarn, a needle lifter (also called a long needle and a needle foot) at the second section, a spring needle (also called a fork needle) at the third section, and a selector (also called a selector piece) acting with the selector.

[0004] In the existing flat knitting machine, the commonly used structure is 2, 3 or 4 sets of cam systems, and the structures of the cam systems are consistent, so that the knitting can be carried out simultaneously to improve the knitting efficiency. For example, the prior patents CN202809165U and CN201354397Y involve two sets of cam systems, and the prior patents CN116971083A (Comparative Document 1), CN201343621Y and CN202099528U involve three sets of cam systems, but the structures of each set of cam systems are consistent.

[0005] The applicant optimized the structure in "2024215065309 A Flat Knitting Machine Three-System Knitting Device", and three systems were arranged on a group of cam bottom plates, wherein the left and right two sets of cam systems each included a transfer (needle lifting) cam mechanism and a knitting cam mechanism, and the middle cam system did not include a transfer cam mechanism and only included a knitting cam mechanism.

[0006] However, after a period of production test, the applicant found that the structure could be further optimized, and therefore developed a triangular layout structure of three-system flat knitting machine, which gave rise to the present case. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a triangular layout structure of three-system flat knitting machine, which further develops a three-system cam structure that can be used for double-sided knitting on the basis of the original structure.

[0008] To achieve the above object, the technical scheme of the utility model is as follows:

[0009] A triangle layout structure of a three-system flat knitting machine, comprising

[0010] The first triangle base plate and the second triangle base plate are each provided with a set of triangle systems at left, middle and right parts; the triangle systems on the first triangle base plate and the second triangle base plate are distributed as follows:

[0011] The middle triangle system is provided with a knitting triangle mechanism and is not provided with a loop shifting triangle mechanism;

[0012] The middle triangle system is provided with a loop shifting triangle mechanism and a knitting triangle mechanism on one side;

[0013] The middle triangle system is provided with a loop shifting triangle mechanism and is not provided with a knitting triangle mechanism on the other side;

[0014] The knitting triangle mechanism at least comprises an upper middle mountain triangle, a lower middle mountain triangle and a density triangle;

[0015] The loop shifting triangle mechanism at least comprises a needle turning triangle and a needle connecting triangle.

[0016] The general flat knitting machine is also provided with two triangle base plates, and the first triangle base plate and the second triangle base plate are arranged on the front and rear machine heads respectively and move together with the machine heads, but during knitting, the first triangle base plate and the second triangle base plate work alternately in a back-and-forth operation process; the three-system triangle structure after the above improvement can make the first triangle base plate and the second triangle base plate work simultaneously during operation, that is, according to the different arrangement of the systems on the two triangle base plates, the knitting machine can selectively work between knitting and needle turning.

[0017] Further, after the first triangle base plate and the second triangle base plate are installed, the left triangle system of the first triangle base plate and the second triangle base plate is provided with a loop shifting triangle mechanism and a knitting triangle mechanism, and the right triangle system is provided with a loop shifting triangle mechanism and is not provided with a knitting triangle mechanism.

[0018] Here, "left" and "right" are in the perspective of the operator facing the flat knitting machine, and are not taken as the reference of the triangle base plate itself, that is, the triangle systems on the first triangle base plate and the second triangle base plate are symmetrically arranged.

[0019] Further, the knitting triangle mechanism in the left triangle system is provided with one or two density triangles.

[0020] When the knitting triangle mechanism in the left triangle system only participates in double-sided knitting, it can be provided with only one density triangle.

[0021] Further, one of the two under-cam triangles is provided with a lifting cam.

[0022] Further, the lifting cam is either a movable structure or a fixed structure.

[0023] According to the requirement of back-and-forth operation during double knitting, the lifting cam provided with a movable structure can be pressed into the cam base by the knitting needle.

[0024] Further, the under-cam triangle and the lifting cam are integrated.

[0025] When the lifting cam is a fixed structure, it can be integrated with the under-cam triangle.

[0026] After the above scheme is adopted, the present application has the following advantages compared with the prior art:

[0027] The three-system cam structure is further optimized, so that it can not only have the double knitting function while reducing the load of the machine head as much as possible, but also realize normal knitting and the turning and transferring functions. BRIEF DESCRIPTION OF DRAWINGS

[0029] Figure 2 is a schematic diagram of embodiment two;

[0030] Figure 3 is a schematic diagram of embodiment three;

[0031] REFERENCE NUMERALS

[0032] the first cam base 1 and the second cam base 2,

[0033] the upper-cam triangle 3, the under-cam triangle 4, the lifting cam 5, and the density cam 6,

[0034] the turning cam 7 and the needle insertion cam 8. DETAILED DESCRIPTION

[0035] The present application will be further described below in combination with the drawings and specific embodiments.

[0036] In the three-system cam structure in the following embodiments, the first cam base 1 and the second cam base 2 are provided with a set of cam systems at the left, middle and right parts thereof, with the angle in the drawings as the reference;

[0037] The middle cam system is provided with a knitting cam mechanism but not a transferring cam mechanism;

[0038] The left cam system is provided with a transferring cam mechanism and a knitting cam mechanism.

[0039] The right-side triangular system is equipped with a shifting triangular mechanism, but not with a weaving triangular mechanism;

[0040] The knitting triangle mechanism includes the upper middle hole triangle 3, the lower middle hole triangle 4, the starting triangle 5, and the density triangle 6. The knitting needle starts from the starting triangle 5 and enters the knitting channel between the upper middle hole triangle 3 and the lower middle hole triangle 4. The knitting density is then controlled by the density triangle 6. This structure is also the most basic knitting structure of the flat knitting machine.

[0041] The shifting triangle mechanism includes a turning triangle 7 and a receiving triangle 8. The receiving triangle 8 and the turning triangle 7 work together for shifting and turning the needle.

[0042] The other functional triangles, such as the needle protection triangle and the needle cleaning triangle, have not been substantially changed in this utility model, and therefore will not be described further.

[0043] Example 1:

[0044] like Figure 1 As shown, in this embodiment, the first triangular base plate 1 and the second triangular base plate 2 are in the weaving triangular mechanism on the left side, and a density triangle 6 is provided on both sides of the upper triangular triangle 3. This arrangement indicates that the triangular system on the left side has both a loop shifting function and a back-and-forth weaving function (including single-sided weaving and double-sided weaving). The functional triangles on the two triangular base plates are symmetrically distributed front and back (with the first triangular base plate as the front knitting head).

[0045] Example 2:

[0046] like Figure 2 As shown, in this embodiment, except that the density triangle distribution of the first triangular base plate 1 and the second triangular base plate 2 in the weaving triangular mechanism on the left side is not symmetrical, the remaining triangle distribution is as in Embodiment 1. However, in this embodiment, the weaving triangular mechanism on the left side of the first triangular base plate 1 only has the density triangle 6 on the right side, and the weaving triangular mechanism on the left side of the second triangular base plate 2 only has the density triangle 6 on the left side.

[0047] At this point, the aforementioned left-side braiding triangular mechanism only has a double-sided braiding function.

[0048] Example 3:

[0049] like Figure 3 As shown, in this embodiment, the remaining mechanisms are the same as in Embodiment 2, but the weaving triangle mechanism on the left side of the first triangular base plate 1 only has the left density triangle 6, and the weaving triangle mechanism on the left side of the second triangular base plate 2 only has the right density triangle 6.

[0050] At this point, the aforementioned left-side braiding triangular mechanism only has a double-sided braiding function.

[0051] That is, when double knitting is performed, the density cam 6 on one side of the left triangular mechanism can be omitted to reduce the load of the machine head, and the density cam 6 itself can be adjusted by mounting and dismounting.

[0052] In the above embodiments, "left" and "right" are referenced to the angle in the drawing, not the angle of the triangular base plate itself after the machine tool is actually set.

[0053] The above is only a specific embodiment of the present application, and the words such as "upper", "lower", "left", "right", "middle" and the like involved in the present application are only for reference, not absolute limitation. Any non-substantial change made by using the present application shall be deemed to infringe the protection scope of the present application.
