AI Technical Summary
In existing cylindrical sock knitting machines, the jacquard pieces get stuck in the bearing rotation pivot point during the jacquard knitting process, making replacement inconvenient. The centrifugal force generated by the rotation increases the processing difficulty of the sinker ring, and the bearing needs to be machined with a jacquard needle rotation pivot point groove, which further increases the processing difficulty.
The structure of the jacquard pattern was improved by adding a limiting hook and a thin extension. The limiting hook hooks onto the sunker bed, and the thin extension stabilizes the operation of the jacquard auxiliary pattern and the sunker pattern. The machining of the bearing rotation pivot groove was eliminated, reducing the machining difficulty.
It simplifies the replacement and maintenance of jacquard pieces, reduces the processing difficulty of sinker rings and bearings, and avoids the jacquard pieces being affected by centrifugal force.

TECHNICAL FIELD
[0001] The utility model relates to the field of cylinder hosiery machine, especially to a hosiery machine jacquard needle selection structure. BACKGROUND
[0002] Hosiery machines can be classified according to needle bed form, needle type and needle cylinder (bed) number; the basic structure of a circular hosiery machine includes a cylindrical needle cylinder, a plurality of needles are arranged on the outer circumferential surface of the needle cylinder, and the needles are used to knit yarn into loops until a complete sock is formed. The upper periphery of the needle cylinder has a steel ring, and various components are arranged on the steel ring along the needle cylinder and cooperate with the needles or yarn when needed to act on the yarn to make various knitting movements. At the same time, there are also various components cooperating with the needle movement on the periphery of the middle and lower parts of the needle cylinder.
[0003] Among them, the existing cylinder hosiery machine knits loops with raised jacquard, as shown in Figure 1 、 Figure 2 The needle cylinder 07 is located below the garter cover 01, the garter steel ring 06 is arranged on the upper part of the needle cylinder 07, the needle selector 05 is arranged around the garter steel ring 06, and the selected jacquard piece 04 is swung forward by the blade of the needle selector with the bottom as the fulcrum 041 and then pushes the jacquard auxiliary piece 03 forward, so as to realize the needle selection function through the garter piece 02.
[0004] However, the above structure has the following disadvantages: 1. The jacquard piece is not convenient to replace when it is stuck in the rotating fulcrum of the bearing 08; 2. The centrifugal force generated by rotation is protected by the garter steel ring, which increases the processing difficulty of the garter steel ring; 3. The bearing needs to be processed with a jacquard needle rotating fulcrum groove, which increases the processing difficulty of the bearing.
[0005] Therefore, the present inventors have made further research and developed a hosiery machine jacquard needle selection structure, which is the result of this case. CONTENT OF THE UTILITY MODEL
[0006] The utility model aims at providing a hosiery machine jacquard needle selection structure, which overcomes the problems in the prior art through improvement of the jacquard piece structure.
[0007] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0008] A hosiery machine jacquard needle selection structure, comprising
[0009] A jacquard piece, one side of the jacquard piece is linked with the blade of the needle selector, and the other side is provided with an extension, the end of the extension is provided with a limiting hook, and the thickness of the extension is thinner than that of the jacquard piece body;
[0010] A jacquard auxiliary piece, the jacquard auxiliary piece is arranged on the side edge of the extension and can be pushed by the jacquard piece body;
[0011] The jack is arranged to be pushed by the jacquard auxiliary piece.
[0012] The structure and function of the jacquard auxiliary piece and the jack are consistent with the prior art, and the jacquard piece is mainly improved, so that the limiting hook for positioning the jacquard piece is extended to the middle of the cylinder and hooks the jack bed, so that the jacquard piece is not affected by the centrifugal force, and the thin extension part can also stabilize the operation of the jacquard auxiliary piece and the jack.
[0013] Further, the length of the extension part is greater than the length of the jacquard auxiliary piece.
[0014] Further, the side of the jacquard piece facing the needle selector guide piece is a sawtooth structure.
[0015] Further, the limiting hook acts on the jack bed, and the jack bed is provided with a bearing.
[0016] The bearing here is the bearing that needs to be machined with the rotation support point of the jacquard needle in the background art, and in the present scheme, the bearing does not need to be machined with the support point.
[0017] After adopting the above scheme, the present application has the following advantages compared with the prior art:
[0018] The replacement and maintenance of the jacquard piece are facilitated, the machining difficulty of the jack ring and the bearing is reduced, and the influence of the centrifugal force on the jacquard piece is avoided. BRIEF DESCRIPTION OF DRAWINGS

[0024] MARK DESCRIPTION
[0025] Jack cover 1, jack piece 2, jacquard auxiliary piece 3,
[0026] Jacquard piece body 4, extension part 41, limiting hook 42,
[0027] Needle selector 5, jack ring 6, needle cylinder 7, bearing 8. DETAILED DESCRIPTION
[0028] The utility model will be further explained in connection with the drawings and specific embodiments.
[0029] As Figures 3-5 shown, a kind of hosiery jacquard needle selection structure, it is arranged between jacquard cover 1 and needle cylinder 7, and its periphery is provided with jacquard ring 6, it includes jacquard piece 2, jacquard auxiliary piece 3, jacquard piece body 4;Wherein, jacquard piece is located in the innermost circle, jacquard piece body 4 and the guide piece of needle selector 5 directly act, to Figure 4 The perspective as reference, then there are several jagged structures in the right side of jacquard piece body 4, it corresponds with the blade of needle selector 5;The left side of jacquard piece body 4 is extension 41, and the extension 41 is long and narrow structure, and its thickness is thinner than jacquard piece body 4, so it forms a gradient groove with jacquard piece body 4, jacquard auxiliary piece 3 and jacquard piece are arranged in the gradient groove, when jacquard piece body 4 is selected by the blade of needle selector 5 and is pushed forward, drive jacquard auxiliary piece 3 and jacquard piece to work.
[0030] The end of extension 41 is a downward limit hook 42, the limit hook 42 can be acted with jacquard bed, when hosiery is in working condition, jacquard piece body 4 will not be thrown out because of centrifugal force, and because of the existence of limit hook 42, so it is not necessary to open again rotating fulcrum groove on bearing 8, simultaneously, the design of jacquard ring 6 no longer needs to consider the protection of jacquard piece body 4.
[0031] The above is only the specific embodiment of the utility model, simultaneously, all the words such as "upper, lower, left, right, middle" etc. as being involved in the utility model, are only for reference, and not absolute limit, all the non-essential changes using the utility model, should belong to the behavior of infringing the protection scope of the utility model.
