Description

Technical Field

[0001] This utility model relates to the field of glove machines, and specifically to a needle selection structure for glove machines. Background Technology

[0002] Computerized glove machines are a type of flat knitting machine. Their basic structure is as follows: between the left and right bases, there are front and rear needle beds. Movable knitting needles are placed in the needle grooves of the needle beds. Triangular base plates are set on the separate front and rear knitting heads. The triangular base plates move horizontally left and right with the knitting heads. Because there are various triangles on the triangular base plates, the needle selection, starting, and clearing actions are performed through the interaction between each triangle and the needle heel of the knitting needle (combination needle), thus completing various knitting functions.

[0003] The selection of knitting needles is done 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 setting needle selection pins in the grooves 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 known as full-mesh knitting), the middle position (corresponding to hanging-mesh knitting), and the low position (also known as zero position, no-knitting position) commonly used in glove knitting. Through the action of the needle selection pin, the cooperation between the knitting needle and the triangular base plate is ultimately affected.

[0004] However, with this type of needle selection structure, once the needle selection pin is set on the needle selection roller, if it is necessary to change the knitting pattern of the glove, the machine needs to be stopped, the needle selection pin needs to be removed, and then the needle selection pin needs to be reinstalled according to the pattern.

[0005] As mentioned in CN207121685U, some devices use an electromagnetic needle selector. Section 0058 of the instruction manual discloses that "the needle selector 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 "knit or not knit" and is used for knitting gloves without complex patterns. It cannot select high, medium and low positions at the same time.

[0006] Therefore, the inventors conducted further research and developed a needle selection structure for a glove machine, which led to this invention. Utility Model Content

[0007] The purpose of this invention is to provide a needle selection structure for a glove machine, which simultaneously achieves flexibility and diversity in glove knitting.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A needle selection structure for a glove machine, including

[0010] Select the needle bird piece; the needle bird piece corresponds and moves in a one-to-one manner with the knitting stitch.

[0011] The needle selector is located on one side of the needle selector plate. The needle selector plate heel of the needle selector contacts the needle selector plate. The contact portion between the needle selector plate and the needle selector plate heel includes at least three different positions.

[0012] The driving component can move the selection needle plate;

[0013] When the drive unit moves the needle selector plate, the needle selector plate heel can switch between different positions on the needle selector plate.

[0014] Although the needle selector 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 during glove knitting. That is, the needle selector bird piece is driven by the drive component, and the swing of the needle selector heel restricts the position of the needle selector bird piece, thereby driving the needle heel of the knitting stitch to switch between high, middle and zero positions.

[0015] Furthermore, the contact portion between the needle selector plate and the needle selector plate heel has a stepped structure, which includes at least one high point, one middle point, and one low point.

[0016] The high, medium, and low points of the needle mesh correspond to the three knitting states of the glove machine.

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

[0018] Three driving positions are formed by the two protrusions and the outer edge of the rotating part itself, which makes it easy to switch the needle bird piece between the three positions.

[0019] Furthermore, the driving component is a driving rod, which pushes or actuates the selection needle to generate movement.

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

[0021] Furthermore, the needle selector is provided with a shaft hole for inserting a rotating shaft; the needle selector and the drive are located on both sides of the shaft hole.

[0022] Furthermore, the high site of the stepped structure of the needlebird scale is located on the side closer to the axis of rotation, the low site is located on the side farther from the axis of rotation, and the middle site is located between the high site and the low site.

[0023] This is an example of normal knitting of the high point of the stepped structure corresponding to the knitting needle.

[0024] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0025] The needle selection mechanism of this invention combines the advantages of the two existing needle selection schemes of glove machines while avoiding their disadvantages, thus ensuring flexible knitting while also providing a multi-position knitting method. Attached Figure Description

[0031] Label Explanation

[0032] Select needle plate 1, contact part 11, rotating shaft 12,

[0033] Needle selector 2, needle selector plate heel 21, (knitting stitch) needle heel 3,

[0034] Rotating component 4, protrusions (41, 42). Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] In this embodiment, the contact portion 11 between the needle selector 1 and the needle selector 2 is a stepped structure, the driving component is a circular rotating component, and the description is based on the example of the driving component and the needle selector being located on opposite sides of the rotating shaft. Figure 1-3 As shown, the states of the glove machine's needle selection structure in the zero, high, and middle positions are respectively displayed. The knitting needle (which is composed of different needle segments, also called a combination needle; in this embodiment, we mainly look at the position of the heel of the lowest knitting needle) is set in the needle groove. Its lower segment is linked with the needle selection bird plate 1. When the needle selection bird plate 1 swings with its pivot 12 as the axis, the heel of the lower segment either protrudes from the needle groove or retracts into the needle groove. Among them, both hanging knitting (middle position) and normal knitting (high position) require the heel to protrude from the needle groove.

[0037] When the needle is in the zero position, the needle selector plate heel 21 of the needle selector 2 is at the lowest point of the stepped structure of the needle selector plate 1 (see reference). Figure 5 At this time, the contact point between the needle plate 1 and the rotating part 4 is also at its lowest position (refer to...). Figure 4 When the needle heel 3 of the knitting needle is in the zero position on the needle bed, it means that this knitting needle does not participate in knitting and will not interact with the triangle on the triangle base plate.

[0038] When a needle at a specific position in the needle groove needs to participate in normal knitting, the rotation of the rotating component 4 causes the highest protrusion 41 of the rotating component 4 to move the needle selector plate 1. Simultaneously, the needle selector plate heel 21 swings, providing support to the needle selector plate 1 at the highest point of the contact portion 11. Figure 2 As shown, at this time, the needle heel 3 protrudes completely from the needle groove and can run along the normal knitting track formed by the triangular base plate to carry out normal knitting work.

[0039] When a needle at a specific position in the needle groove is needed for the hanging stitch knitting, the rotation of the rotating component 4 causes the needle selector plate 1 to move due to the second highest protrusion 42 of the rotating component 4. Simultaneously, the needle selector plate heel 21 swings. At this time, because the needle selector plate heel is blocked by the high point of the contact portion 11, it can only stop at the midpoint of the contact portion 11, such as... Figure 3 As shown, at this time, the needle heel 3 protrudes from the needle groove and can run along the hanging mesh weaving track formed by the triangular base plate to carry out hanging mesh weaving work.

[0040] In this embodiment, one rotation of the rotating component is considered as one needle selection cycle. First, the high-position needle is selected, then the middle-position needle is selected. After the needle selection is completed by the needle selector plate, the rotating component returns to its initial position.

[0041] Resetting the needle clip is a common technique in this field and will not be described in detail here.

[0042] The above are merely specific embodiments of this utility model. Whether the needle bird piece moves actively or passively is within the scope of the inventive concept of this case. At the same time, all terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as an infringement of the protection scope of this utility model.
