Description

Technical Field

[0001] This invention relates to the field of flat knitting machines, and specifically to a multifunctional electromagnetic needle selection method. 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 pins, three-position knitting is achieved.

[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 simultaneously select the three power positions of high, medium and low.

[0006] Therefore, the inventors conducted further research and developed a multifunctional electromagnetic needle selection method, which led to this invention. Summary of the Invention

[0007] The purpose of this invention is to provide a multifunctional electromagnetic needle selection method, which simultaneously achieves flexibility and versatility in glove knitting.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] A multifunctional electromagnetic needle selection method, which drives the needle selection bird to swing through a driving component and coordinates with the movement of the needle selector to achieve three-position knitting states of the knitting needle, includes the following actions:

[0010] When selecting the high-position knitting action, the knitting needles that need to participate in the high-position knitting are lifted to the high position through the needle selector. After the corresponding needle selector plate heel starts working, it forms support for the needle selector plate, so that the needle heel of the corresponding knitting needle is in the high position.

[0011] When selecting the middle knitting action, lift the knitting needles that need to participate in the middle knitting to the middle position through the needle selector. After the corresponding needle selector's heel starts working, it supports the needle selector, so that the needle heel of the corresponding knitting needle is in the middle position.

[0012] When selecting the zero position, the needle selector corresponding to the knitting stitch that is not involved in knitting will not work.

[0013] In the above actions, the side of the needle selector plate adjacent to the needle selector plate heel includes three different positions, and each of them can contact the needle selector plate heel, corresponding to the three states of the needle heel of the knitting stitch.

[0014] In this design, the needle selector, needle selector, and knitting needle (the bottom part of the needle) are arranged horizontally on the needle bed in a one-to-one correspondence. The needle selector and the knitting needle are linked, and the heel of the knitting needle can protrude from the needle bed, which is a common technique in the field. The needle selector can only swing its heel between two positions. Therefore, to achieve three position selection, it is necessary to control different positions of the needle selector to coordinate with the heel of the needle selector, so that the change in the relative position between the heel of the needle selector and the needle selector corresponds to the three positions during glove knitting, thereby achieving the switching of the needle heel between high, medium, and low positions. Since the needle selector and the knitting needle are set up in a one-to-one correspondence, and the heel of the needle selector can also be controlled independently, the above solution can guarantee the selection of high, medium, and low positions, and can also change the glove knitting pattern without stopping the machine.

[0015] Furthermore, when the needle selector plate is driven by the same driving component, the needle selector plate is first driven to bring the heel of the knitting stitch to the high position, and the corresponding needle selector plate heel works to keep the heel in the high position; then the needle selector plate is driven to bring the heel of the knitting stitch to the middle position, and the corresponding needle selector plate heel works to keep the heel in the middle position.

[0016] Furthermore, when the needle selection bird plate is driven by different driving components, the needle heel of the knitting needle that needs to participate in high-level knitting is pushed to the high-level state, and the needle heel of the knitting needle that needs to participate in middle-level knitting is pushed to the middle-level state.

[0017] Furthermore, the side adjacent to the needle selector plate heel includes three different positions. The three different positions of the needle selector plate side are, in order, the low position, the middle position, and the high position. When the needle selector plate is driven to make the needle heel of the knitting stitch reach the middle position, the needle selector works. The needle selector plate heel is restricted by the high position of the needle selector plate and can only stay in the middle position.

[0018] Furthermore, the needle selector plate moves or oscillates under the drive of the drive component, so that the needle selector plate heel contacts the low-order, middle-order, and high-order positions on the needle selector plate.

[0019] Furthermore, the driving mechanism drives the needle-shaped plate in various ways, including rotary drive, oscillating drive, or linear drive.

[0020] Rotary drive refers to driving in a manner such as cam; oscillating drive can refer to the method disclosed in prior patent CN201045161Y; linear drive refers to pushing the needle pick when the driving component performs linear motion.

[0021] Furthermore, the driving component is a rotating component, and the outer ring of the rotating component has two protrusions of different heights.

[0022] 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.

[0023] Furthermore, as the rotating component rotates, the contact point between the needle selector and the rotating component switches between the protrusion and the outer ring of the rotating component, and the auxiliary needle selector heel switches between the low-level, middle-level, and high-level positions of the needle selector.

[0024] Furthermore, the contact portion between the needle selector plate and the needle selector plate heel has a stepped structure, which constitutes the low-level, middle-level, and high-level positions of the needle selector plate.

[0025] 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.

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

[0027] It combines the advantages of the two existing needle selection schemes of glove machines while avoiding their disadvantages, thus ensuring flexible knitting while also having a multi-position knitting method. Attached Figure Description

[0033] Label Explanation

[0034] Select needle plate 1, contact part 11, rotating shaft 12,

[0035] Needle selector 2, needle selector plate heel 21, (knitting stitch) needle heel 3,

[0036] Rotating component 4, protrusions (41, 42). Detailed Implementation

[0037] The present invention will be further described below with reference to 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 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.

[0039] At 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 point, the contact point between the needle plate 1 and the rotating part 4 is also at the lowest position (see reference). Figure 4 When the needle heel 3 is in the zero position on the needle bed, it means that this needle does not participate in knitting and will not interact with the triangle on the triangle base plate.

[0040] When a needle at a specific position in the needle slot 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 higher position of the contact portion 11. Figure 2 As shown, at this time, the needle heel 3 of the knitting needle 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.

[0041] When a needle at a specific position in the needle groove is needed for the hanging stitch knitting, the rotation of the rotating member 4 causes the needle selector plate 1 to move due to the second highest protrusion 42 of the rotating member 4. Simultaneously, the needle selector plate heel 21 swings. At this time, because the needle selector plate heel is blocked by the higher position of the contact portion 11, it can only remain at the middle position 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 stitch weaving track formed by the triangular base plate to carry out hanging stitch weaving work.

[0042] Taking a knitting needle as an example, its various working states are as follows:

[0043] If the desired pattern does not require this needle to participate in the knitting work on this row, the selector heel remains stationary, leaving the needle heel in the zero position, i.e. Figure 1 state.

[0044] If this needle needs to participate in normal knitting (full stitch) in this row, the rotating component rotates, coordinating with the oscillation of the needle selector's heel, so that the needle heel is in a high position, i.e. Figure 2 state.

[0045] If the needle needs to participate in the hanging stitch knitting in this row, the rotating component rotates, coordinating with the oscillation of the needle selector's heel, so that the needle heel is in the center position, that is... Figure 2 state.

[0046] Taking a row of knitting needles as an example, within one cycle of the rotating part, the above method can be used to first select the high-position knitting needle from the zero position (that is, the needle selector works so that the needle heel is in the high position), and then select the middle-position knitting needle from the zero position. Since the needle selector plate heel is blocked by the high-level position of the needle bird plate when the middle-position knitting needle is selected for the second time, it will stay in the middle level of the needle bird plate, thus forming the middle-position knitting needle.

[0047] Resetting the needle clip is a common technique in this field and will not be described in detail here.

[0048] The above are merely specific embodiments of the present invention. The active or passive movement of the needle selector and the change of the position of the needle selector are all 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 the present invention are for reference only and are not absolute limitations. Any non-substantial modifications made using the present invention shall be considered as an infringement of the protection scope of the present invention.
