Description

Technical Field

[0001] The present invention relates to the field of glove knitting machines, and in particular to a needle selecting device for a glove knitting machine. Background Art

[0002] Computer glove knitting machine is a kind of flat knitting machine, and its basic structure is: front and rear needle beds are arranged between the left and right bases, movable knitting needles are arranged in the needle grooves of the needle beds, and cam bottom plates are arranged on the split front and rear heads, and the cam bottom plates move left and right with the random heads; because various cams are arranged on the cam bottom plates, the needles are selected, started and cleared through the interaction of the needle butts of the cams and knitting needles (combination needles), so as to complete various knitting functions.

[0003] The selection of knitting needles is carried out through a needle selection mechanism. The needle selection mechanism commonly used in existing glove machines is a needle selection roller, as shown in CN106521790A. By arranging a needle selection pin in the groove of the needle selection roller, the surface of the needle selection roller forms three contact surfaces of different heights corresponding to the high position (corresponding to normal knitting, also called full-mesh knitting), the middle position (corresponding to tuck knitting), and the low position (also called zero position, non-knitting position) commonly used in glove knitting. The needle selection bird piece interacts with it, which ultimately affects the coordination between the knitting needle and the triangular base plate.

[0004] However, in this type of needle selection structure, once the needle selection pin is set on the needle selection drum, if the knitting style of the gloves needs to be changed, the machine needs to be stopped to remove the needle selection pin and then reinstall the needle selection pin according to the style.

[0005] There is also a method, such as that mentioned in CN207121685U, which adopts an electromagnetic needle selector to select needles. Paragraph 0058 of its specification discloses that "the needle selection head body 941 can swing left and right through the selection function of the coil 943 to meet the need of needle selection." However, this method can only select "knit or not knit", which is used for knitting gloves that do not have complex styles, and it is impossible to select high, medium and low positions at the same time.

[0006] Therefore, the inventor conducted further research and developed a needle selection device for a glove machine, which resulted in the present invention. Summary of the invention

[0007] The object of the present invention is to provide a glove machine needle selection device, which realizes the flexibility and diversity of glove machine knitting.

[0008] In order to achieve the above object, the technical solution of the present invention is as follows:

[0009] A glove machine needle selection device, comprising

[0010] The needle selector, needle selector bird piece, and knitting stitches are set one by one, among which,

[0011] The needle selector bird piece is provided with an axial hole, and the needle selector bird piece rotates around the axial hole; one end of the needle selector bird piece is linked with the knitting stitch, and the other end is linked with the driving member, and the side of the needle selector bird piece contacts with the needle selector plate;

[0012] The contact point between the needle selector bird piece and the needle selector piece heel is provided with three steps of different heights;

[0013] When the driving member drives the needle selection bird piece to rotate, the needle selection bird piece can stay at three different positions, so that the needle selector plate heel can switch at different step positions of the needle selection bird piece.

[0014] Although the heel of the needle selector can only swing between two positions, by setting at least three different positions on the bird piece, the change in the relative position between the needle selector heel and the needle selector bird piece corresponds to the three positions when the gloves are knitted, that is, the needle selector bird piece is driven by the driving member, and the heel of the needle selector piece swings to limit the position of the needle selector bird piece, thereby driving the butt of the knitting stitch to switch between the high position, the middle position and the zero position.

[0015] Furthermore, the contact portion between the needle selector bird piece and the needle selector piece butt is a stepped structure, which at least includes a high point, a middle point, and a low point.

[0016] The high point, middle point and low point of the needle selection bird piece correspond to the three knitting states of the glove machine.

[0017] Furthermore, the driving member is a rotating member with a circular cross-section, and the outer ring of the rotating member is provided with two protrusions of different heights.

[0018] Three driving positions are formed by two protrusions and the outer ring edge of the rotating part itself, so that the needle selection bird piece can be switched between the three positions conveniently.

[0019] Furthermore, the driving member is a driving rod, and the driving rod pushes or toggles the needle selection bird piece to move.

[0020] The driving rod structure may refer to the method disclosed in the prior patent CN201045161Y.

[0021] Furthermore, the shaft hole of the needle selector bird piece is used to pass the rotating shaft; the needle selector and the driving member are respectively located on both sides of the shaft hole.

[0022] Furthermore, the high point of the needle selection bird piece step position is located on the side close to the rotating shaft, the low point is located on the side away from the rotating shaft, and the middle point is located between the high point and the low point.

[0023] This is an embodiment of normal knitting of the knitting needles corresponding to the high points of the stepped structure.

[0024] Further, when the driving member pushes to lift the needle selection bird plate, the needle selector plate heel moves to the high position of the needle selection bird plate step position.

[0025] The high and low points of the aforementioned needle selection bird piece step positions are taken as reference relative to the needle selection bird piece itself.

[0026] After adopting the above scheme, the present invention has the following advantages compared with the prior art:

[0027] The needle selection method of the present invention takes into account the advantages of the two needle selection schemes of the existing glove knitting machines and avoids their disadvantages, that is, it ensures flexible knitting while having a multi-position knitting method.

[0034] Needle selection bird piece 1, contact part 11, rotating shaft 12,

[0035] Needle selector 2, needle selector butt 21, needle butt (of knitting stitches) 3,

[0036] Rotating member 4, protrusions (41, 42). DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] In this embodiment, the contact portion 11 between the needle selector 1 and the needle selector 2 is a stepped structure, the driving member is a circular rotating member, and the driving member and the needle selector are located on both sides of the rotating shaft. Figure 1-3As shown, it shows the states of the glove machine needle selection structure at zero position, high position and middle position respectively. The knitting needle (which is composed of different needle segments, also called combined needles, in this embodiment, mainly looks at the needle butt position of the knitting stitch of the lowest segment) is arranged in the needle groove, and its lower segment is linked with the needle selection bird piece 1. When the needle selection bird piece 1 swings with its rotating shaft 12 as the axis, the needle butt of the lower segment either protrudes from the needle groove or is retracted into the needle groove. Among them, both tuck knitting (middle position) and normal knitting (high position) require the needle butt to protrude from the needle groove:

[0039] When the knitting needle is at zero position, the needle selector plate heel 21 of the needle selector 2 is at the lowest point of the step-type structure of the needle selector plate 1 (refer to Figure 5 ), at this time, the contact point between the needle selection bird piece 1 and the rotating member 4 is also at the lowest position (reference Figure 4 ), the needle butt 3 is in the zero position on the needle bed, which means that this knitting needle does not participate in knitting and will not interact with the triangle on the triangle bottom plate.

[0040] When a knitting needle at a certain position in the needle groove is required to participate in normal knitting, the highest protrusion 41 of the rotating member 4 moves the needle selector bird plate 1 through the rotation of the rotating member 4, and at the same time, the needle selector plate heel 21 swings to form a support for the needle selector bird plate 1 at the high position of the contact part 11, such as Figure 2 As shown, at this time, the needle butt 3 completely protrudes from the needle groove and can run along the normal knitting track formed by the triangular bottom plate to perform normal knitting work.

[0041] When a knitting needle at a certain position in the needle groove is required to participate in the tuck knitting, the second highest protrusion 42 of the rotating member 4 also rotates to move the needle selector bird 1, and the needle selector plate heel 21 swings. At this time, since the needle selector plate heel is blocked by the high position of the contact part 11, it can only stay at the middle position of the needle selector bird 1 on the contact part 11, such as Figure 3 As shown, at this time, the needle butt 3 half protrudes from the needle groove and can run along the tuck knitting track formed by the triangular bottom plate to perform tuck knitting work.

[0042] In this embodiment, one rotation of the rotating member is regarded as one needle selection cycle, the high-position needle is selected first, and then the middle-position needle is selected. The rotating member returns to the initial position after the needle selector plate heel completes the needle selection.

[0043] The needle selection bird piece will be reset, which is a common technical means in this field and will not be described in detail here.

[0044] The above is only a specific embodiment of the present invention. The schemes of active or passive movement of the needle selection bird piece are all within the inventive concept of this case. At the same time, all words such as "up, down, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
