Description

TECHNICAL FIELD

[0001] The utility model relates to the field of glove machine, especially a glove machine needle selection structure. BACKGROUND

[0002] The computer glove machine belongs to one kind of flat knitting machine, and its basic structure is that front and rear needle beds are arranged between left and right bases, movable knitting needles are arranged in the needle grooves of the needle beds, and cam plates are arranged on the split front and rear heads, and the cam plates move horizontally with the heads; various cams are arranged on the cam plates, and the needle butts of the cams and knitting needles (combination needles) interact to perform needle selection, needle lifting and needle clearing actions, and complete various knitting functions.

[0003] The selection of the knitting needles is performed through a needle selection mechanism, and the commonly used needle selection mechanism of the existing glove machine is a needle selection roller, as shown in CN106521790A, a needle selection pin is arranged in the groove of the needle selection roller, the surface of the needle selection roller forms three contact surfaces with different heights corresponding to high position (corresponding to normal knitting, also called full gauge knitting), middle position (corresponding to drop gauge knitting) and low position (also called zero position, non-knitting position) respectively, the needle selection roller interacts with the needle selection bird piece, and finally affects the cooperation between the knitting needle and the cam plate.

[0004] However, once the needle selection pin is arranged on the needle selection roller, if it is necessary to change the knitting style of the glove, the needle selection pin needs to be removed after the machine is stopped, and then the needle selection pin is reinstalled according to the style.

[0005] There is also an electromagnetic needle selector for needle selection as disclosed in CN207121685U, and the specification 0058 discloses that the needle selection head body 941 can swing left and right through the selection action of the coil 943 to meet the needs of needle selection. However, this method can only select “knitting or not knitting”, and is used for knitting gloves without complex styles, and cannot simultaneously select high, middle and low positions.

[0006] In view of the above technical problems, the applicant proposes a glove machine needle selection device in “CN119332403A”, at least three different positions are arranged on the bird piece, the relative position between the needle selector piece butt and the needle selection bird piece is changed to correspond to three positions (hereinafter referred to as three positions) during glove knitting, that is, a rotating piece (with a protrusion) drives the needle selection bird piece, the position of the needle selection bird piece is limited by the swing of the needle selector piece butt, so as to switch the needle butts of the knitting stitches between high position, middle position and zero position.

[0007] However, in the subsequent actual production test, the applicant finds that the existing needle selector structure occupies a large space, the more dense the knitting needles on the needle bed, the more difficult it is to arrange the needle selector, and the needle selectors will be squeezed in space.

[0008] Therefore, the inventor makes further researches and develops a glove machine needle selection structure, and the present case is generated. Utility model content

[0009] The glove machine needle selection structure is reasonable in spatial layout of elements during three-position needle selection.

[0010] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0011] A glove machine needle selection structure comprises

[0012] A plurality of swing members, the swing member comprises a linkage of a push piece and a top piece, wherein the push piece swings under the action of a driving member;

[0013] A plurality of driving members are arranged around the outside of the swing member, and the driving members drive and limit the swing amplitude of the push piece;

[0014] In the ring formed by the plurality of driving members, the angles formed between the push pieces and the top pieces of adjacent swing members are different, and the positions of the driving members correspond to the push pieces.

[0015] In the previous prior application, due to the dense distribution of the needle bed knitting needles and the corresponding needle selection bird pieces, it is difficult for the needle selector for limiting the position of the needle selection bird piece to be distributed horizontally at the same horizontal position. Therefore, by forming a plurality of different angles between the push piece and the top piece, the adjacent driving members are arranged around the swing member, so that the conflict in the horizontal space can be avoided, thereby better achieving the individual control of the needle bed needle selection bird piece.

[0016] Further, the plurality of swing members are arranged side by side and arranged on the same shaft.

[0017] Unlike the previous needle selector, in the present embodiment, the swing member and the driving member are separated, and the swing member swings around the shaft.

[0018] Further, the driving member is a U-shaped electromagnetic wire package, and the push piece is arranged in the U-shaped groove.

[0019] The push piece swings in the U-shaped groove through the electromagnetic wire package, so as to achieve the same effect as the needle selector.

[0020] Further, four driving members with different distribution positions are arranged around the swing member arranged side by side, and the driving members do not interfere with each other.

[0021] According to the actual space required by the driving member, it is more reasonable to arrange four driving members with different distribution positions around the swing member.

[0022] Further, the needle selection bird piece is driven by a rotating member, and the rotating member and the driving member are arranged on two sides of the needle selection bird piece.

[0023] Because the driving member and the swinging member occupy a large space, the rotating member for driving the needle selection bird piece to lift needs to be arranged separately from the aforementioned components.

[0024] Further, the rotating member is in a cylindrical shape, and the outer arc edge is provided with protrusions with different heights.

[0025] The rotating member is similar to the rotating member of the prior application.

[0026] Further, the width of the groove of the U-shaped groove is consistent with the swinging range of the top piece.

[0027] The swinging range of the top piece only needs to cover the range of each step of the needle selection bird piece.

[0028] After the above scheme is adopted, compared with the prior art, the utility model has the following advantages:

[0029] Considering the actual space occupied by each element, through further reasonable design on the basis of the prior patent of the applicant, flexible three-position needle selection of glove knitting is more easily realized. BRIEF DESCRIPTION OF DRAWINGS

[0035] Swinging member 1, pushing piece 11, top piece 12, rotating shaft 13,

[0036] Electromagnetic wire package 2, control panel 21,

[0037] Needle selection bird piece 3, step 31, rotating member 4, needle butt 5 of knitting needle. DETAILED DESCRIPTION

[0038] The utility model will be further described below in combination with the drawings and specific embodiments.

[0039] First, a brief explanation of the prior patent: In order to achieve flexible knitting of the glove machine while having a three-position knitting method, the applicant adopted the technical solution in the prior patent application that "the contact point between the needle selector plate and the needle selector plate heel is provided with three steps of different heights; when the rotating component drives the needle selector plate to rotate, the needle selector plate can stop at three different positions, thereby allowing the needle selector plate heel to switch between different steps of the needle selector plate".

[0040] In this embodiment, the needle selector 3 has an overall L-shaped structure, with its end interacting with the needle heel 5. One side of its tail is a rotating component 4, and the other side is equipped with a swinging component 1 and a driving component. For example... Figure 1 As shown, the left side of the needle selector 3 is a rotating part 4, which is a cylindrical structure. The outermost arc edge is provided with two protrusions of different heights, which can be used to lift the needle selector 3 when rotating. That is, when the left end of the needle selector 3 is squeezed by the rotating part 4, the right end will be lifted up, thereby changing the position of the needle heel 5.

[0041] During the lifting process, a series of steps 31 of varying heights are provided at the lower center of the needle selection plate 3. Referring to the description of the prior patent, this can achieve the switching of the needle heel between three working positions through the cooperation of the swinging member 1 and the lifting of the rotating member 4 (also referring to...). Figure 2 ).

[0042] Reference for the fit between the swing component 1 and the drive component Figure 3 The main body of the oscillating component 1 is a circular ring. Several oscillating components 1 are mounted on the same rotating shaft. Each oscillating component 1 corresponds to a needle selection plate 3. The circular ring of the oscillating component 1 is provided with a lever 11 and a top plate 12. The top plate 12 is linked with the needle selection plate 3, and the lever 11 is linked with the driving component. The driving component is arranged around the oscillating component 1. The position of the lever 11 of the oscillating component 1 is determined according to the position of the driving component. (Refer to...) Figure 4 As shown, in this embodiment, the driving components are arranged horizontally at four different horizontal positions, so the position of the paddle 11 is also changed accordingly.

[0043] Specifically, the driving component is set as a U-shaped electromagnetic coil 2. The electromagnetic coil 2 itself has a certain width and thickness, which cannot be made to match the thickness of the needle bird plate 3. Therefore, by setting it in a ring shape, the adjacent driving components do not have spatial conflicts. The lever 11 is set in the U-shaped groove of the electromagnetic coil 2. The electromagnetic coil 2 is controlled by the control panel 21. When the current in the electromagnetic coil 2 changes, the lever 11 swings in the U-shaped groove, thereby driving the top plate 12 to swing.

[0044] The embodiment conceives how to reasonably arrange the driving members, and the above is only a specific embodiment of the conception, meanwhile, words such as "upper", "lower", "left", "right", "intermediate" and the like involved in the utility model are only used for reference, not absolute limitation, and any non-substantial change using the utility model should belong to the behavior of infringing the protection range of the utility model.
