Technical Field
[0001] This utility model relates to the field of glove machines, and specifically to an electromagnetic 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, non-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] To address the aforementioned technical issues, the applicant proposed a needle selection device for a glove knitting machine in "CN119332403A". By setting at least three different positions on the needle selector plate, the change in the relative position between the needle selector plate heel and the needle selector plate corresponds to three positions during glove knitting (hereinafter referred to as the three working positions). That is, the needle selector plate is driven by a rotating component (with a protrusion), and the needle selector plate heel swings to limit the position of the needle selector plate, thereby driving the needle heel of the knitting stitch to switch between high position, middle position and zero position.
[0007] In subsequent production and research and development, the applicant found that the existing needle selector structure occupies a large space. The denser the knitting needles on the needle bed, the more difficult it is to set up the needle selector, and they will cause space compression between each other. Therefore, the applicant applied for a needle selector structure for a glove machine in 2025203377906. The idea is to use an electromagnetic coil wrapped around the outside of the swinging component to drive and limit the swing amplitude of the lever.
[0008] Based on the above concept, the applicant further improved the structure of the electromagnetic coil and the swing component during the actual production test, making the structure more reasonable and convenient for production.
[0009] Therefore, the inventors conducted further research and developed an electromagnetic needle selection structure for glove machines, which led to this invention. Utility Model Content
[0010] To achieve the above objectives, the technical solution of this utility model is as follows:
[0011] An electromagnetic needle selection structure for a glove machine, comprising:
[0012] The oscillating component includes a drive end and a working end that are linked together. The oscillating component and the selection needle bird plate are arranged in a corresponding row.
[0013] A substrate, with several substrates arranged around the swinging component;
[0014] Several electromagnetic coils are arranged side by side on each substrate. Each electromagnetic coil includes a coil frame and an electromagnetic coil. The coil frame has a hollow structure in the middle, and electromagnetic coils are wound on both sides of the coil frame. The electromagnetic coils are powered by the substrate.
[0015] The driving ends of adjacent swinging components are located in the hollow structure of different wire frames, and move back and forth due to the attraction of electromagnetic coils on both sides, thereby causing the working ends to swing accordingly.
[0016] Through actual production tests, the structure of the electromagnetic coil was optimized by separating the electromagnetic coils on both sides and controlling them through their respective circuits, making the operation of the oscillating component more stable and thus making the control of the needle selection plate more accurate.
[0017] Furthermore, the driving end of the oscillating component is a permanent magnet or has a permanent magnet embedded in it, and the working end is a lever. The permanent magnet and the lever are sleeved on the same shaft.
[0018] The permanent magnet is driven by electromagnetic coils on both sides of the electromagnetic coil, giving it the ability to swing back and forth, thereby driving the lever to swing and supporting the selection needle at different positions. The structure of the selection needle is based on a prior patent.
[0019] Furthermore, the substrates are disposed in four different positions on the oscillating member. In the initial state, the working ends of the oscillating members disposed on each substrate are arranged in the same way, and the angles formed by the driving ends and working ends of the different basic oscillating members are different.
[0020] Furthermore, the oscillating components arranged in a row are supported by a support structure.
[0021] Due to their own weight, when the oscillating parts are arranged in a row during actual production, the oscillating parts closer to the center are more likely to sink. Therefore, they need to be supported by a support structure to prevent them from affecting the control of the needle bird plate.
[0022] Furthermore, the support structure includes a support rod aligned with the direction of the swinging member, and several support members are provided on the support rod, with the ends of the support members connected to the sides of the swinging member.
[0023] The support of the support component should not affect the swing of the swing component.
[0024] Furthermore, the contact between the support and the swinging member is either rolling contact or sliding contact; when it is sliding contact, the end of the support is an arc-shaped structure; when it is rolling contact, the end of the support is provided with balls.
[0025] Furthermore, the driving end of the swing component is connected to the inner ring, and the working end is connected to the outer ring. The inner ring is fitted inside the outer ring and is fitted on the shaft.
[0026] Furthermore, the inner ring is made of plastic.
[0027] Plastic parts are used to support the overall weight of the sturdy swinging components.
[0028] By adopting the above solution, this utility model has the following advantages compared with the prior art:
[0029] 1. The structure of the electromagnetic coil has been optimized, with the electromagnetic coils located on both sides and controlled by independent circuits, making the operation of the oscillating component more stable and thus making the control of the needle selection plate more accurate.
[0030] 2. The support structure prevents the oscillating component from sinking due to its own weight, which would reduce the control accuracy of the needle bird. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0041] Since this utility model is based on further improvements on a series of prior patents, the interaction between the working end of the swing member (i.e., the lever in the embodiment) and the needle bird plate will not be described in detail here.
[0042] like Figure 1 , 2 As shown, an electromagnetic needle selection structure for a glove machine includes a shaft 4 between the left and right bases for passing through a swinging component 1. The swinging components 1 are arranged side-by-side along the shaft 4, each corresponding to a needle selection plate. Four base plates 3 are arranged around the swinging components 1. An electromagnetic coil 2 is arranged inside each base plate 3, on the side facing the swinging component 1. Figure 3 As shown, the electromagnetic coil 2 includes a coil frame 21. The left and right sides of the coil frame 21 are I-shaped structures for winding the coil. An iron core 22 is set in the middle of the coil. The coil is powered through the lead wire 23, which ultimately generates a magnetic field on both sides of the coil frame.
[0043] The wire frame 21 has a U-shaped structure with a narrow opening in the middle. This U-shaped structure is used to accommodate the driving end of the swing member 1. In this embodiment, the driving end is a long strip permanent magnet 11. The permanent magnet 11 swings left and right by switching the circuits of the coils on both sides. The permanent magnet 11 extends out from the inner ring of the swing member 1. In order to reduce weight, the inner ring can be made of plastic. The inner ring is sleeved on the outside of the shaft 4, and an outer ring is sleeved on the inner ring. The outer ring is provided with the working end lever 12 of the swing member 1. When the permanent magnet 11 swings under the drive of the electromagnetic coil 2, the lever 12 swings accordingly, thereby interacting with the needle pick.
[0044] Due to the different distribution of substrates 3, the angles of the permanent magnet 11 and the lever 12 of the oscillating member 1 on different substrates 3 are different, as shown in the reference. Figure 4As shown, in the initial state, the levers 12 of all the swinging parts 1 are in the same position, while the permanent magnets 11 are set in different orientations depending on the location of the electromagnetic coil 2.
[0045] Since all the oscillating elements 1 are mounted on the same shaft 4, and shaft 4 is only supported by the base at the left and right ends, it will undergo slight deformation under its own weight. This causes the oscillating elements 1 closer to the center to be more affected, thus impacting the accuracy of the lever 12 acting on the needle selection plate. To solve this technical problem, refer to... Figure 5 As shown, a support rod 5 is provided below all the swinging parts 1. A support member 51 is provided on the support rod 5. One end of the support member 51 is fixed to the support rod 5, and the other end is in contact with the outer ring of the swinging part 1. The end of the support member 51 is processed into an arc-shaped structure that does not affect the operation of the swinging part 1. It can support the shaft 4 and the swinging part 1, thereby avoiding the deformation of the components from affecting the entire needle selection structure.
[0046] As another embodiment, a movable ball can be embedded in the end of the support member 51 so that the support member 51 and the swing member 1 are in rolling contact, but the processing difficulty is higher.
[0047] The above are merely specific embodiments of this utility model. Furthermore, 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 infringing upon the protection scope of this utility model.
