Description

Technical Field

[0001] This utility model relates to the field of glove machines, and specifically to a glove machine follow-up needle selection mechanism. Background Technology

[0002] Scene technology

[0003] 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.

[0004] 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.

[0005] 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.

[0006] 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.

[0007] 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 selection piece, the change in the relative position between the needle selector heel and the needle selection piece corresponds to three positions during glove knitting (hereinafter referred to as the three working positions). That is, the needle selection piece is driven by a rotating component (with a protrusion), and the needle selector heel swings to limit the position of the needle selection piece, thereby driving the needle selection heel to switch between high position, middle position and zero position.

[0008] However, in subsequent actual production tests, 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 recently developed "A needle selection structure for a glove machine" as shown in 2025203377906, which improved the driving structure of the "paddle" that works with the needle selector in "three positions".

[0009] In the aforementioned case, a single rotating component drives two protrusions of different heights to lift the needle pick in order to cooperate with the "picking".

[0010] However, this driving method lifts all the needles together, resulting in greater resistance to the rotating parts, insufficient flexibility, and a higher power requirement for the rotating parts.

[0011] Therefore, the inventors conducted further research and developed a follow-up needle selection mechanism for glove machines, which led to this invention. Utility Model Content

[0012] The purpose of this invention is to provide a follow-up needle selection mechanism for a glove machine, which makes the driving of the needle selection sprocket more flexible when the glove machine selects needles.

[0013] To achieve the above objectives, the technical solution of this utility model is as follows:

[0014] A glove machine follow-up needle selection mechanism, including

[0015] The needle selection plate has three working steps;

[0016] The drive unit is located on one side of the needle selector and moves with the machine head. The drive unit can drive the needle selector to swing back and forth in three different positions.

[0017] The paddle can switch between three different positions of the needle selector when the drive unit drives the needle selector to swing.

[0018] The concept of this case is mainly based on prior patents. Since the driving component needs to move with the machine head, the driving component in this case is relatively fixed in position, that is, it is located on the "outer side" of the needle selector (relative to the needle plate), while the lever is located on the "inner side" of the needle selector. The lever here can be a "lever" similar to the heel of the needle selector, or it can be a structure similar to the swing component driving the lever in 2025203377906. The machine head here refers to the component with a triangular base plate and various functional triangles.

[0019] The needle selection mechanism constructed using the above scheme has a driving component that follows the movement of the machine head. Therefore, it only needs to drive the needle selection blades that will participate in the work, and works in conjunction with the paddle to form a function similar to the needle selection pin in the needle selection roller. As a result, its needle selection is more flexible, and the number of driven needle selection blades is smaller, which can reduce the burden on the driving component.

[0020] Furthermore, a drive unit is provided on each side of the machine head, and the drive unit is connected to the machine head through a connector.

[0021] Since the machine head moves back and forth, setting a drive unit on each side of the machine head allows for more flexible needle selection control.

[0022] Furthermore, the driving component includes a needle selection plate, which is driven by a push rod and linked to the machine head via a mounting base.

[0023] The needle-selecting tablet press has an initial state, a half-extension state, and a maximum extension state under the drive of the push rod, which correspond to the three power positions of the needle-selecting tablet. The machine head is also connected to the synchronous belt, so the needle-selecting tablet press moves with the machine head.

[0024] Furthermore, the two sides of the needle-pressed tablet are inclined edges with a tilt angle.

[0025] Since the selector pin itself has a component similar to a return spring, we only need to consider how to facilitate the driving component to drive the selector pin.

[0026] Furthermore, when the needle selection tablet is in its maximum extension state, the needle selection tablet will select the needle heel to the high position.

[0027] When the selection needle is in the maximum extension state, the corresponding selection needle heel is in the high position. When the selection needle is not extended, the selection needle heel is in the zero position. When the selection needle is in the half extension state, the selection needle heel is in the middle position.

[0028] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0029] By improving the applicant's prior technology, the needle selection structure of the three-position needle selector is made more reasonable, resulting in better operating performance. Attached Figure Description

[0040] Top rod 10, irregular hole 101. Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 , 1-1 As shown, the two sides of the glove machine (excluding the upper yarn rack and lower box) are inclined and can move back and forth along the upper and lower slide rail assemblies, while the needle bed 6 corresponding to the machine head 5 is fixed. The needle groove of the needle bed 6 is equipped with hook needles, needle selectors, etc., and the needle selector bird plate 1 is located at the tail of the needle selector, which is located at the bottom.

[0043] Based on the above basic structure, the follow-up needle selection mechanism of the glove machine described in this embodiment also includes a needle selection plate 2. The needle selection plate 2 is disposed adjacent to the outer side of the L-shaped needle selection plate 1 (relative to the needle bed 6), and is mounted on a mounting base 21. The mounting base 21 is connected to the timing belt 7 via a connecting block 8, and the upper machine head 5 is also connected to the timing belt 7. When the needle selection plates 2 are respectively disposed on both sides of the machine head 5 on the same side of the needle bed 6, it can be ensured that the machine head 5 can pre-select or select needles through the needle selection plate 2 during its back-and-forth movement. In order to cooperate with the needle selection plate 1 and prevent it from being blocked by adjacent needle selection plates 1 during lateral movement, the two sides of the needle selection plate 2 are set as inclined sides 22 with an inclination angle. The movement of the needle selection plate is accomplished by a push rod driven by a motor.

[0044] Specifically:

[0045] like Figure 2As shown, when the needle selection plate 2 set in the mounting base 21 is in the initial state, the lever 4 does not act on the three-position step of the needle selection plate 1, the return spring 11 of the needle selection plate 1 is in the natural state, and the needle selection heel 3 linked with the needle selection plate 1 is in the "zero position" state.

[0046] like Figure 3 As shown, when the needle press plate 2 is pushed out and is in a semi-pull-out state, the needle selector plate 1 swings, so that the lever 4 can act on the middle step of the needle selector plate 1. At this time, the needle selector heel 3 is in the "middle" state.

[0047] like Figure 4 As shown, when the needle pressing plate 2 is pushed out to its maximum extension state, the lever 4 can act on the high step of the needle selection plate 1, at which time the needle selection heel 3 is in the "high position" state.

[0048] like Figure 5 As shown, a limiting rod 9 is provided on the side of the push rod 10. Several irregularly shaped holes 101 are formed on the push rod 10. Bolts or fixing pins are installed on the limiting rod 9 and pass through the irregularly shaped holes 101, keeping the limiting rod 9 relatively fixed. When the motor drives the push rod 10, causing relative displacement between the push rod and the limiting rod, the push rod 10 can remain relatively stationary at different positions due to the limitation of the irregularly shaped holes. A bearing 23 can be used as a transition piece between the push rod 10 and the needle-selecting pressure plate 2, enabling linkage between the push rod 10 and the needle-selecting pressure plate 2.

[0049] Although there are existing three-section electric linear actuators, their structure is more complex and their operating cost is higher.

[0050] 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.
