Description

Technical Field

[0001] The invention belongs to the technical field of knitting machinery, and in particular relates to an offset needle hook and a knitting needle, which are suitable for a knitting needle structure used for knitting cloth in a knitting machine. Background Art

[0002] Knitting machines are important equipment in the textile industry, used to weave yarn into knitted fabrics. In the knitting process, knitting needles play a vital role. Their structure and shape directly affect the knitting looping process, the productivity of the knitting machine and the quality of the knitted fabric. At present, in the design process of knitting needles, the needle hook is usually directly set at the front end of the needle bar, and the axis of the needle hook is consistent with the axis of the needle bar. This design is prone to problems during the knitting process, especially when two knitting needles arranged opposite to each other on the knitting machine are cross-knitted. Since the needle hook of one of the knitting needles needs to be inserted into the spring sheet on the needle bar of the other knitting needle, it is very easy to generate extrusion force when the needle hook is inserted into the needle bar spring sheet, causing the needle bar to deform or even break at the spring sheet, thereby affecting the normal operation of the knitting machine and the quality of the knitted fabric.

[0003] In the prior art, there are studies on the influence of needle structure on the normal operation of knitting machines and the quality of knitted fabrics, such as patent application CN214168320U - an impact-resistant looping knitting needle, which reduces the yarn looping speed by setting a speed bump on the inner side of the needle hook and the back of the needle tongue seat, thereby preventing the impact damage between the needle tongue and the needle hook and the needle tongue seat caused by excessive knitting speed, and improving the durability of the knitting needle to a certain extent; another example is patent application CN118756420A - a composite needle for knitting knitting machines, which reduces the burden on the coil when transferring the coil by designing an avoidance groove and a special needle tongue structure, and considers leaving a certain gap between the needle blade and the needle hook to store the coil, thereby improving the coil transfer process, but it is difficult to ensure that the needle hook will not be deformed and broken under the long-term support of the extrusion stress when inserting the needle bar spring sheet, so it is difficult to fundamentally guarantee the stable operation of the knitting machine and the quality of the knitted fabric. To this end, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0004] The object of the present invention is to provide an offset needle hook and a knitting needle so as to solve the problem raised in the above-mentioned background technology that it is difficult to ensure that the needle hook will not be deformed or broken due to the long-term extrusion stress when inserted into the needle bar spring sheet, thereby making it difficult to fundamentally guarantee the stable operation of the knitting machine and the quality of the knitted fabric.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an offset needle hook, comprising a connecting portion and a bending portion, wherein the connecting portion is connected to the front end of a needle rod connected to the needle hook and its position is offset relative to the axis of the needle rod, the bending portion is connected to the end of the connecting portion by bending and its position is offset relative to the axis of the connecting portion and its end is aligned with the axis of the needle rod, the bending portion, the connecting portion and the needle rod are cross-arranged in spatial layout, and the end of the bending portion is fixed to the needle rod in a suspended state through the connecting portion and does not directly contact the needle rod.

[0006] Furthermore, the connecting portion extends from both sides of the axis of the needle bar along the front end direction of the needle bar and deviates toward one side of the axis of the needle bar at the connection with the needle bar; the starting end of the connecting portion is directly connected to the front end of the needle bar.

[0007] Furthermore, the starting end of the bending portion is connected to the end of the connecting portion and completes a smooth arc turn at the connection; after turning, the bending portion continues to extend along a path opposite to the offset direction of the connecting portion until its end is aligned with the axis position of the needle rod.

[0008] In addition to the above technical solutions, there is also a knitting needle with the offset needle hook.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts a needle hook offset setting structure, so that the connecting part and the curved part are offset to different degrees relative to the needle bar and the connecting part, respectively, forcing the connecting part, the curved part and the needle bar to form a spatially crossed layout, effectively avoiding the problem of the needle hooks of two knitting needles arranged opposite to each other on the knitting machine inserting into the needle bar spring sheet during cross knitting to generate extrusion stress, greatly reducing the risk of needle bar deformation or breakage, extending the service life of the needle bar, and reducing the maintenance cost of the knitting machine, thereby fundamentally ensuring the stable operation of the knitting machine and the quality of the knitted fabric; 2. The present invention helps to maintain the stability of the tension of the yarn by designing the connection part offset to one side of the needle bar axis, so that the knitted fabric is more uniform and smooth, and also reduces the impact between the needle latch and the needle hook and the needle latch seat, significantly reduces the wear of the knitting needle, prolongs the service life of the knitting needle, reduces the downtime and cost caused by replacing the knitting needle, and improves the production efficiency; 3. The present invention is designed to deflect the bent portion along a path opposite to the deflection direction of the connecting portion, so that the end of the bent portion can be fixed on the needle bar in a suspended state but not in direct contact with the needle bar, which not only increases the structural strength of the knitting needle, but also improves its flexibility and adaptability, so that the knitting needle can better adapt to different types of yarns and knitting processes, and also enables the yarn to be more evenly distributed around the needle hook, which is conducive to forming a knitted fabric with a compact structure and uniform consistency, thereby improving the overall quality of the knitted fabric; 4. The present invention arranges an offset needle hook on the knitting needle, so that the knitting needle can avoid the extrusion stress caused by the needle hook inserting into the needle bar spring piece, and at the same time, it can make the maintenance of the knitting machine simpler, reduce the maintenance cost and difficulty, and also reduce the impact of shutdown maintenance on the production progress. It can be applied to various knitting machines, especially knitting machines. Due to the unique structure and function, the knitting process is more efficient and stable, providing new impetus for the development of the textile industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following examples are used to further illustrate the content of the present invention, but do not limit the application of the present invention. Embodiment 1:

[0013] See also Figure 1-Figure 4 In this embodiment, an offset needle hook is provided, comprising a connecting portion 1 for connecting a needle bar and a bending portion 2 for weaving yarn into a loop, wherein the connecting portion 1 is connected to the front end of a needle bar 3 connected to the needle hook and its position is offset relative to the axis of the needle bar 3, and the bending portion 2 is connected to the end of the connecting portion 1 by bending and its position is offset relative to the axis of the connecting portion 1 and its end is aligned with the axis of the needle bar 3, so that the end of the bending portion 2 is fixed on the needle bar 3 in a suspended state through the connecting portion 1 and does not directly contact the needle bar 3, so that the bending portion 2, the connecting portion 1 and the needle bar 3 are cross-arranged in spatial layout.

[0014] The offset needle hook described above is specifically offset in that: the connecting portion 1 extends from both sides of the axis of the needle bar 3 along the front end direction of the needle bar 3 and is offset toward one side of the axis of the needle bar 3 at the connection with the needle bar 3, so that the starting end of the offset connecting portion 1 is directly connected to the front end of the needle bar 3; The starting end of the curved portion 2 is connected to the end of the connecting portion 1 and completes a smooth arc turn at the connection. After the smooth arc turn, it continues to extend along a path opposite to the offset direction of the connecting portion 1 until its end is aligned with the axis position of the needle rod 3.

[0015] The working principle and use process of this embodiment are as follows: Figure 1-Figure 4 As shown in the figure, the offset needle hook is directly connected to the needle bar 3 of the knitting needle (the functions and structures of conventional equipment such as knitting needles are well known in the art, and the connection settings are also common knowledge, so no further explanation is given here, and it is not shown in the drawings) and forms an integrated structure with the needle bar 3, which can solve the problem of the needle hook inserting into the needle bar spring sheet and generating extrusion stress when two knitting needles arranged opposite to each other on the knitting machine are cross-knitted, greatly reducing the risk of deformation or breakage of the needle bar, extending the service life of the needle bar, and reducing the maintenance cost of the knitting machine, thereby fundamentally ensuring the stable operation of the knitting machine and the quality of the knitted fabric; When the yarn needs to be knitted into coils, the operator must first determine the needle distance according to the required knitting density to select a suitable needle plate (the functions and structures of conventional equipment such as needle plates are well known in the art, and the connection settings are also common knowledge, so they are not explained here and are not shown in the drawings), and then place a number of knitting needles with offset needle hooks in the needle grooves of the selected needle plate, and then call out the required knitting needles with offset needle hooks according to the knitting length. The offset setting of the connecting portion 1 and the bending portion 2 can effectively avoid the situation where the two knitting needles arranged opposite to each other on the knitting machine are inserted into the needle bar springs during cross-knitting to generate extrusion stress. The problem is solved, and then the yarn is moved to the front end of the bend 2 by using the braider on the knitting machine (the functions and structures of the knitting machine and other conventional equipment equipped with the braider are well known in the art, and the connection settings are also well known common sense, so no further explanation is given here and it is not shown in the drawings). The yarn is then slid to the connection between the end of the bend 2 and the needle tongue on the knitting needle and the needle tongue is opened at the same time. At this time, the yarn enters the groove formed by the bend 2 and the connecting part 1 under the opening of the needle tongue, and then the yarn in the groove is weaved into a coil by the braider of the knitting machine, and so on. The operation is repeated in this way to complete the weaving of the product and finally form a knitted fabric. Embodiment 2:

[0016] See also Figure 1-Figure 4 As another object of the present invention, a knitting needle is provided, in which the above-mentioned offset needle hook is provided. Therefore, the knitting needle can obtain any beneficial effect of the offset needle hook described above, which will not be repeated here.
