Description

Technical Field

[0001] The utility model relates to the field of flat knitting machine needles, in particular to a hidden knitting needle. Background Art

[0002] The reciprocating motion of the triangle bottom plate of the flat knitting machine drives the knitting needle group to rise and fall, thereby weaving the fabric. The existing knitting needle group usually consists of a drop needle, a push needle and a needle selection plate. Multiple knitting needle groups are arranged on the needle plate at equal intervals. The push needle is used to push the drop needle to different weaving positions. The current knitting needles have the following disadvantages due to unreasonable structural design: 1. During the weaving process, the heel of the knitting needle is exposed outside the needle groove. When the triangle reciprocates, the exposed heel is easy to collide with the triangle, thereby damaging the triangle; 2. If the heel of the knitting needle is exposed outside the needle groove when the knitting needle is not working, it is easy to be displaced after colliding with the triangle, affecting the normal weaving of the yarn.

[0003] Therefore, it is necessary to implement corresponding improvements to existing knitting needles. Utility Model Content

[0004] The utility model aims to provide a sinking needle structure to improve the problems of fabric deformation and yarn breakage caused by the knitting needles exposing the needle grooves when not knitting in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hidden knitting needle, comprising

[0007] Needle bar;

[0008] A needle hook connected to the front end of the needle bar;

[0009] The needle tongue is connected to the connection between the needle bar and the needle hook to control the opening and closing of the needle hook;

[0010] The needle transfer spring sheet is arranged on the side of the needle bar;

[0011] The needle tail is connected to the rear end of the needle bar;

[0012] The lower edge of the needle tail gradually rises from the end close to the needle rod to the end away from the needle rod to form a triangular gap with the bottom of the needle groove when the needle is removed. A butt is also provided on the upper part of the end of the needle tail away from the needle rod, and the upper end of the butt is not higher than the needle groove when the needle rod is retracted into the needle groove.

[0013] Preferably, an anti-collision groove extending along the width direction of the butt is provided on the side surface of the butt.

[0014] Preferably, the upward angle of the lower edge of the needle tail is 2.5°.

[0015] Preferably, a pin is further provided at the lower portion of the needle tail away from one end of the needle rod, and the lower bottom surface of the pin is arranged lower than the lower bottom surface of the needle rod.

[0016] Preferably, the needle tail is gradually bent to one side from an end close to the needle rod to an end far away from the needle rod.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The lower edge of the needle tail is set upward, so that when the butt of the knitting needle is subjected to a vertical action, it can be pried with the needle bar as a fulcrum, thereby burying the entire butt into the needle groove to prevent the heel of the non-working knitting needle from colliding with the reciprocating triangle.

[0019] 2. An anti-collision groove is provided on the side of the butt. In this state, even if the butt of the knitting needle is hit by the cam, the butt can be broken and separated from the knitting needle immediately, avoiding repeated wear of the cam by the bent butt.

[0020] 3. The 2.5° upward angle of the lower edge of the needle tail ensures that after the needle tail of the knitting needle sinks into the needle groove under pressure, the needle shaft and needle hook of the knitting needle will not be higher than the needle groove.

[0021] 4. Set the stitches to ensure the stability of the knitting needles during operation and prevent the knitting needles from warping backwards.

[0022] 5. The needle tail has a certain curvature. When the knitting needle is placed in the needle groove, the curved needle tail will elastically abut against the groove walls on both sides of the needle groove, thereby improving the stability of the knitting needle in the needle groove.

DETAILED DESCRIPTION

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 4 A hidden knitting needle 10 shown includes a needle bar 1 as the main body of the knitting needle, the front end of the needle bar is connected to a needle hook 2, and a needle tongue 3 can be turned over and connected at the connection between the needle hook and the needle bar. When knitting, the opening and closing of the needle hook is controlled by turning the needle tongue, thereby realizing effective control of each step of yarn knitting. At the same time, a reverse spring sheet 6 is also provided on the side of the needle bar to assist in the needle turning operation during knitting. In addition, a needle tail 4 is connected to the rear end of the needle bar 1. This solution realizes the hiding of the knitting needle in the needle groove when it is not working through the cooperation between the needle tail and the needle plate.

[0032] Specifically, the entire needle tail 4 extends along the length direction of the needle bar, while its lower edge 41 is tilted upward. Specifically, the lower edge of the needle tail 4 gradually tilts upward from the end close to the needle bar to the end away from the needle bar. Preferably, the tilting angle is 2.5° with the lower edge of the needle bar as the best. In this tilted state, the needle tail is pressed into the needle groove, and the needle bar and the needle hook part are tilted with the lower bottom surface of the needle bar as the fulcrum, and still will not be higher than the needle groove. At the same time, a butt 42 is also provided on the upper part of the needle tail away from the end of the needle bar, and the upper end of the butt is not higher than the needle groove 61 when the knitting needle is not working (not extending out of the needle groove).

[0033] It should be noted that during the operation of the computer flat knitting machine, the knitting needles may not be in place. In this case, the heel of the plate is exposed above the needle groove. When the triangle moves, the heel will collide with the triangle in order to reach the preset position. The heel that is collided with the triangle will become completely stuck after being skewed, and will cause continuous, reciprocating collision and scraping to the triangle. An anti-collision groove 44 is also provided on the heel. It should be noted that the anti-collision groove extends along the width direction (horizontal direction) of the heel, so that the thickness of the position where the anti-collision groove is provided on the heel becomes thinner, and when the heel is hit by the triangle, it can be disconnected here, so that the disconnected heel is disconnected from the needle tail, avoiding continuous damage to the triangle.

[0034] In addition, it should be noted that in order to ensure the stability of the needle-out process of the knitting machine 10, especially to prevent the needle tail from tilting upward during the needle-out process, a downwardly protruding pin 43 is also provided at the lower part of the needle tail away from the end of the needle bar 1. Specifically, the lower bottom surface of the pin is set lower than the lower bottom surface of the needle bar to ensure that when the knitting machine 10 is out of the needle, the pin can abut against the bottom of the needle groove, keeping the knitting needle horizontally extending out of the needle groove.

[0035] Finally, to ensure the stability of the knitting needle 10 in the needle groove, the needle tail 4 is gradually bent toward one side from the end close to the needle bar 1 to the end away from the needle bar. It should be noted that the chord height of the bent needle tail is greater than the width of the needle groove, so as to ensure that the needle tail can abut against both sides of the needle groove like a spring sheet when in the needle groove.

[0036] Working principle: Figure 3 , Figure 4As shown, a plurality of needle grooves 61 are provided on the needle plate 6, and the knitting needles 10, the needle pusher 7, and the needle selector 8 are installed in the needle grooves. It should be noted that the needle groove provided on the needle plate provides a groove at the location of the pin 43, so that the pin that is pressed and sunken can enter therein. Specifically, when the knitting needle 10 is not pushed out of the needle groove, the butt 42 on the needle tail is pushed by the triangle and flips downward with the connection between the needle tail and the needle rod as a fulcrum. At this time, the pin sinks into the groove, and the butt is buried in the needle groove, and the reciprocating triangle will not collide with the butt. When the knitting needle is selected and pushed out, the pin exits the groove and is guided by the bottom of the needle groove so that the butt extends out of the needle groove again and enters the working state. In the above manner, this scheme completely pushes the knitting needle that is not in the working state into the needle groove, thereby preventing the butt on the knitting needle from causing collision damage to the reciprocating triangle.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
