Description

Technical Field

[0001] The utility model relates to a computerized flat knitting machine, in particular to a resettable knitting needle. Background Art

[0002] Computerized flat knitting machines are an important production tool for knitting fabrics and garments. The knitting needles of existing computerized flat knitting machines are placed in the needle slots. When knitting, they are driven by the triangle assembly to complete a series of actions. The existing problem is that the existing knitting needles can only slide horizontally back and forth in the needle slots, and the heels of the knitting needles that are in contact with the triangle assembly are always exposed outside the needle slots. When the knitting needles are not required to move, the exposed heels may collide with the moving triangle assembly, which may damage the knitting needles at the least or the machine head or needle plate at the worst.

[0008] Preferably, the slot width of the connecting slot is smaller than its maximum width, and the connecting head is placed in the connecting slot so as not to be withdrawn from the slot.

[0009] Preferably, the connecting groove has an arc-shaped guide groove wall, and the connecting head has an arc-shaped portion that fits smoothly with the guide groove wall. When the transition needle flips, it rotates with the arc-shaped portion in contact with the guide groove wall as a fulcrum.

[0010] Preferably, the connecting groove is in an open circular shape, and the connecting head is adapted to the connecting groove and is slidably placed in the connecting groove.

[0011] Preferably, the upper edge of the needle tail has an avoidance slope that slopes downward from one side of the needle rod body to the one side of the needle tail, and after the transition needle is flipped down, the lower edge of the extension rod of the transition needle abuts against the avoidance slope.

[0012] Preferably, the end surface of the connection between the knitting needle rod body and the knitting needle tail is higher than the notch of the connecting groove to form a first limiting surface; the end surface of one end of the extension rod connected to the connecting head is higher than the connecting head to form a second limiting surface; after the transition needle is flipped up, the first limiting surface abuts against the second limiting surface.

[0013] Preferably, the first limiting surface is in a step shape, and the second limiting surface is matched with the first limiting surface.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] 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. Example

[0035] like Figures 1 to 5 The resettable knitting needle shown in the figure is composed of a knitting needle body 1 which can move horizontally in a needle groove and a transition needle 2 which is connected to the knitting needle body and can be completely sunk into the needle groove after being subjected to downward pressure.

[0036] like Figures 1 to 3 As shown, the knitting needle body 1 includes a knitting needle rod body 11 with a knitting needle head portion connected to the front end, and the lower edge of the knitting needle rod body is in smooth contact with the bottom of the needle groove so that it can slide along the bottom of the needle groove. A knitting needle tail 12 is connected to the rear end of the supporting rod body away from the knitting needle head. It should be noted that a connecting groove 13 is provided at the connection between the knitting needle tail and the knitting needle rod body. Specifically, Figure 3 As shown, the overall groove shape of the connecting groove is a purse-shaped groove with a narrow groove opening and a large interior, so as to ensure that the connecting head of the transition needle entering therein will not fall out of the groove opening of the connecting groove.

[0037] It should be noted that if Figure 4 As shown, in order to realize the upside-down connection between the transition needle and the knitting needle body, the transition needle includes an extension rod 22, which extends horizontally, and the front end of the extension rod is connected to the connection head 21 set in the connection groove. It should also be noted that, as Figure 1 As shown in FIG. 1 , there is a certain gap between the lower edge of the extension rod and the upper edge of the needle tail. The existence of this gap provides the extension rod with the connecting head as a fulcrum to flip downward. It should be noted that, as Figure 5 As shown, when the extension rod is turned down to the right position, the entire extension rod is sunk into the needle groove.

[0038] It should be noted that the tail of the extension rod in this solution protrudes upward to form a heel 222, which is higher than the needle groove when the extension rod is horizontal, so that it can contact the triangle assembly and facilitate the triangle assembly to drive the knitting needle. At the same time, the tail of the extension rod protrudes downward to form a stitch. The stitch 223 smoothly abuts against the bottom of the needle groove during the knitting needle movement to keep the extension rod horizontal. When the knitting needle is not knitting, the knitting needle body retreats into the needle groove, and the stitch is located above the groove opened on the needle groove. At this time, the heel exposed on the upper part of the needle groove can be easily sunk into the groove after being pushed downward by the reset triangle.

[0039] As a preferred embodiment of the above embodiment, in order to ensure the smooth rotation of the connecting head in the connecting groove, the connecting groove has an arc-shaped guide groove wall 131. The connecting head has an arc-shaped portion 211 that fits smoothly with the guide groove wall, and the arc-shaped portion is arranged concentrically with the guide groove wall. When the butt of the transition needle is pressed and turned down, the connecting head rotates smoothly in the guide groove wall with the arc-shaped portion as a fulcrum.

[0040] It should be noted that, in the above-mentioned embodiment, the gap between the lower edge of the extension rod and the upper edge of the needle tail can be formed by reducing the lower edge of the extension rod or the upper edge of the needle tail. However, as a preference, the connecting rod plays a role in transmitting thrust, and its strength is related to the stability of the subsequent operation of the needle. For this reason, the preferred embodiment of this scheme is to achieve it in the form of reducing the needle tail. Specifically, the upper edge of the needle tail 12 can be reduced obliquely, that is, the upper edge of the needle tail is tilted downward from the side of the needle rod body 11 to the side of the needle tail to form an inclined avoidance slope 121. Figure 2 As shown, when the transition needle sinks into the needle groove, the lower edge of the extension rod can abut against the avoidance slope.

[0041] It should also be noted that in this solution, the avoidance slope can also serve the purpose of controlling the degree of downward turning, that is, to ensure that after the transition needle turns downward until the extension rod abuts against the avoidance slope, the push pin can abut against the rear end surface of the pin to push the pin of the transition needle out of the groove at the bottom of the needle groove.

[0042] In this solution, when the transition needle is pushed up, there is still the following problem, that is, how to prevent the transition needle from being pushed up too high to prevent the overly high sheet butt from colliding with the machine head. In detail, this can be achieved through the following structure.

[0043] Specific as Figures 1 to 4 As shown, the connection between the needle bar 11 and the needle tail is not smoothly connected, so as to form a surface that is higher than the notch of the connecting groove 13. This surface has a blocking effect and is defined as the first limit surface 111. At the same time, the connection between the extension rod 22 and the link head 21 is also not smoothly connected, so as to leave a surface that is opposite to the first limit surface and abuts against the first limit surface when the extension rod is lifted to a horizontal state, preventing the extension rod from continuing to flip up. It should be noted that in this solution, the surface left at the connection between the extension rod and the link head is defined as the second limit surface.

[0044] Working principle: When installing the needle plate structure, insert the connecting head of the transition needle into the connecting groove from the side so that the transition needle and the knitting needle body form an integral whole. Then place the integrated pointer in the needle groove. At this time, the pin of the transition needle sinks into the groove so that the entire transition needle turns down and sinks into the needle groove. At this time, the heel is also located in the needle groove. In the working flat knitting machine head part, the triangle component therein will not contact the heel sunk into the needle groove, and the probability of needle collision is greatly reduced. When the knitting needle needs to work, the rear end of the transition needle is pushed by the push needle so that the pin exits the groove and enters the needle groove. At this time, the pin abuts against the bottom of the needle groove, and the heel is also exposed from the needle groove. The triangle component can easily drive the knitting needle to move through the exposed heel. Example

[0045] like Figures 6 to 10 As shown, the difference between this scheme and Example 1 is that the shape of the connecting groove in this scheme is an open circle. At the same time, the connecting head 21 is also a circle that matches the connecting groove to ensure that the connecting head can rotate unimpeded in the connecting groove. It should be noted that in this scheme, the arc portion 211 of the connecting head includes the entire portion that is placed in the connecting groove and is concentric with the connecting groove. The guide groove wall in the connecting groove also includes a circular groove wall in the connecting groove. It should be noted that the connecting groove adopts an open circular structure, which can make the connecting head rotate more smoothly therein, thereby realizing a smoother up and down flipping of the transition needle in the needle groove. Example

[0046] like Figures 11 to 15 As shown, in this solution, the first limiting surface has a step-shaped fold bend to form a positioning constraint of multiple surfaces. In contrast, the second limiting surface is also bent in a corresponding step-shaped manner. So that when the transition needle is raised to a horizontal state, the multiple curved surfaces on the first limiting surface and the second limiting surface can still fit and abut.

[0047] It should be noted that the purpose of implementing the present scheme is that by bending and stepping the first limit surface and the second limit surface, it is possible to achieve simultaneous calibration of multiple reference points, thereby ensuring the accuracy of the transition needle when it is lifted and preventing the transition needle from being lifted excessively.

[0048] 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.
