Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flat knitting machine, especially to a flat knitting machine needle structure with a turning needle piece. BACKGROUND

[0002] The computer flat knitting machine is a double needle plate latch needle weft knitting machine, through the machine head and the cam mechanism arranged on the cam bottom plate of the machine head, that is, the cam system reciprocates along the guide rail in the process of the machine head, drives the knitting needle arranged in the needle bed (needle plate) needle groove to move up and down along the needle groove, and completes the knitting of the fabric under the cooperation of the cam mechanism and the pulling mechanism.

[0003] Among them, the knitting needle includes a composite needle with a needle hook and a latch needle separated, and there is also a common hook needle with the latch needle pivoted below the needle hook, in the structure of the latter, the turning needle piece (transfer piece) for transferring is arranged on the side edge of the needle body, the end thereof extends to the needle rod below the needle hook, and a certain gap is formed between the needle rod, that is, the turning needle piece is used to expand the loop when the loop is transferred between the front and rear needle beds to facilitate the insertion of the loop needle, but when knitting relatively tight loops, the turning needle piece is subjected to relatively large pressure of the loops, so that the gap between the turning needle piece and the needle rod is too small, which causes the loop needle (that is, the knitting needle on the other side) not to be easily inserted into the working gap, thereby affecting the subsequent processing.

[0004] In CN221297225U, the structure of the needle head and the turning needle piece itself is designed, so that the working gap can be maintained, and an additional spacer is additionally provided between the turning needle piece and the needle rod, so that the gap can be maintained, but the processing is relatively complex, and the stability is not high enough.

[0005] Therefore, the inventor has made further research on this, and has developed a flat knitting machine needle structure with a turning needle piece, and the present case is generated. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at providing a flat knitting machine needle structure with a turning needle piece, which can ensure that the gap between the turning needle piece and the needle rod can make the loop needle smoothly inserted through simple design.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0008] A flat knitting machine needle structure with a turning needle piece, comprising

[0009] The needle body is provided with a mounting groove for arranging the mounting part of the turning needle piece;

[0010] The needle rod is connected with the needle body, and the needle rod is provided with a containing groove for arranging the end part of the turning needle piece;

[0011] The boundary between the needle body and the needle rod is provided with a blocking line part, which is raised relative to the periphery and used for keeping a gap between the turning needle piece and the needle rod for the entry of the loop needle.

[0012] The needle body and the needle rod are substantially integrated, but in order to block the loop, the width of the boundary is obviously different, and the blocking line part is formed, so that the relative width is defined respectively to illustrate the structure; the mounting part of the turning needle piece is fixed in the mounting groove, and the end part can slide relative to the accommodating groove; in the prior art, one end of the mounting groove is a slope, and the other end close to the boundary (not only the blocking line part) directly extends out and is consistent with the low surface of the needle body, and the accommodating groove provided at the needle rod is similar to the mounting groove, which is not described here. Figure 3

[0013] In the concept of the utility model, by lifting the blocking line part at the boundary between the needle body and the needle rod, the gap between the turning needle piece and the needle rod can be kept, and the loop needle can pass through the gap.

[0014] Further, the highest surface of the blocking line part is consistent with the upper surface of the needle rod, and the blocking line part is integrally designed with the needle body and the needle rod.

[0015] Here, the upper surface of the needle rod is based on the surface where the accommodating groove is located.

[0016] Further, the blocking line part is an L-shaped structure and extends from the boundary between the needle body and the needle rod to the accommodating groove.

[0017] The specific structure of the blocking line part is optimized, and the description of the part of the blocking line part that extends to the accommodating groove is equivalent to disclose the inclination direction of the part of the blocking line part.

[0018] Further, there is a separation belt between the accommodating groove and the blocking line part.

[0019] The separation belt further plays a role in supporting the turning needle piece, and has a better gap keeping effect.

[0020] Further, the blocking line part is formed with a slope surface in two directions of the L-shaped structure.

[0021] The slope surface at the needle rod is used for receiving the initial entry of the loop needle.

[0022] After the above scheme is adopted, compared with the prior art, the utility model has the following advantages:

[0023] The structure of the knitting needle itself is improved, so that the loop needle can work smoothly, the structure is simple, the processing difficulty is low, and the stability is high. BRIEF DESCRIPTION OF DRAWINGS

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] A knitting needle generally comprises a hook, a needle bar 1 connected to the hook, and a needle body 2 connected to the needle bar 1. The needle body 2 is provided with a mounting groove 21 for arranging the mounting portion of the transfer plate 3, and the needle bar 1 is provided with a receiving groove 11 for accommodating the end of the transfer plate 3. In this embodiment, Figure 1 The flat knitting machine needle structure with a needle transfer plate 3 shown in the figure has a relatively wide needle body 2 and a relatively narrow needle bar 1, and an L-shaped thread retaining portion 4 is formed at the boundary between the two.

[0033] refer to Figure 1-1 The thread blocking portion 4 is inclined from right to left and from high to low at the needle body 2 to form a slope 42, and is inclined from inside to outside and downward at the needle rod 1 to form a slope 41, and the thread blocking portion 4 and the needle body 2 and the needle rod 1 are designed as an integral whole; at the same time, the upper surface of the thread blocking portion 4 is flush with the upper surface of the needle rod 1 and extends to the side of the accommodating groove 11, but the accommodating groove 11 is not connected to the slope of the thread blocking portion 4, but an isolation belt 12 is provided between the two, and the isolation belt 12 is referred to Figure 2 As shown, it can also be used to support the needle plate 3.

[0034] At this time, refer to Figure 2 From the perspective of FIG, it can be seen that a certain gap 5 is left between the turning piece 3 and the slope 41 of the thread blocking part 4, and the gap will not be completely closed even when the turning piece 3 is under pressure; when the coil needle enters, it first reaches the slope 41, then slides down and presses the coil (to prevent the coil from floating up and interfering with the connecting coil), and then passes through the slope 42 between the turning piece 3 and the needle body.

[0035] Compared with the structure improvement of the turning piece 3, the rigidity under pressure is better, and the turning piece 3 will not deform due to long time working; and compared with the interval provided between the turning piece 3 and the needle body 2, the processing is simpler, the wire blocking part 4 can be integrally formed, and the manufacturing cost is low.

[0036] The above is only a specific embodiment of the present application, meanwhile, the words such as "upper", "lower", "left", "right", "middle" and the like involved in the present application are only for reference, not absolute limitation, and any non-substantial change made by using the present application shall belong to the behavior of infringing the protection scope of the present application.
