Description

Technical Field

[0001] The utility model relates to the technical field of the production of computer flat knitting needles, and particularly relates to an improved knitting needle. Background Art

[0002] The computer flat knitting machine drives the latch needles to move back and forth in the needle bed of the flat knitting machine. By driving the latch needles on one side of the needle bed to pass through the latch needles on the other side, the textile yarn is hooked back to complete the knitting action.

[0003] According to the patent previously disclosed by the applicant, the utility model patent application with the publication number: CN217869379 and the publication date of November 22, 2022, specifically discloses an improved structure of a flat knitting needle, including a needle hook, a needle tongue, a needle shank and a spring piece. There is a groove on the side wall of the needle shank, and the spring piece is located in the groove. The needle shank is composed of a needle rod and a needle body. The spring piece is successively composed of a first arc section, a horizontal section, a second arc section and a fixed section from front to back. The head of the first arc section, the horizontal section and the fixed section are all attached to the bottom wall of the groove. The outermost bulging part of the second arc section is lower than the surface of the side wall of the needle shank; a cavity is formed between the first arc section and the needle shank, and an outward convex part is provided at the tail of the first arc section along its width direction; the bending line formed between the tail of the first arc section and the head of the horizontal section is inclined and parallel to the inclination direction of another knitting needle inserted into the cavity. Its main technical effect is: there is only one real knitting cavity. During the process of turning needles and transferring loops, the height of the bulge of the second arc section can be minimized, effectively avoiding the friction between the spring piece and the tooth piece, and fully improving the service life of the spring piece and the tooth piece.

[0004] During the use of the previously applied knitting needles, it is found that during the process of turning needles and transferring loops, the oblique pulling force of the loop will cause the first arc section to deform, that is, to become flat. At the same time, when the knitting needle slides from the first arc section into the second arc section, the needle tongue is sometimes difficult to open, resulting in the inability to complete the normal turning of needles and transferring of loops. Therefore, an improved knitting needle is proposed, aiming to solve the problem of high error rate of turning needles in the process of the previously applied knitting needles. Content of the Utility Model

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] Please refer to Figures 1-12, An improved knitting needle, including a knitting needle body 1, wherein a reed mounting groove 11 is provided on the knitting needle body 1, and further includes a purl reed 2, the purl reed 2 is fixedly installed inside the reed mounting groove 11, the purl reed 2 includes a first arc segment 21, a second arc segment 22 and a flat segment 23, and a triangular groove 25 is provided between the first arc segment 21 and the second arc segment 22.

[0035] The purl reed 2 is riveted in the reed mounting groove 11 on the knitting needle body 1 through a rivet. The first arc segment 21 at the head of the purl reed 2 abuts against the knitting needle body 1, and the triangular groove 25 between the first arc segment 21 and the second arc segment 22 abuts against the knitting needle body 1, so that a first purl cavity 26 is formed between the first arc segment 21 and the triangular groove 25, and a second purl cavity 27 is formed between the second arc segment 22 and the triangular groove 25. As Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 shown, during the purling process, when another knitting needle body 1 is inserted into the first purl cavity 26 and moves, the bottom end of the triangular groove 25 first moves into the needle hook of another knitting needle body 1 and abuts against the latch of another knitting needle body 1, driving the latch of another knitting needle body 1 to open. As another knitting needle body 1 moves, the needle hook enters the second purl cavity 27 and moves to hook the yarn to be purled. At this time, when another knitting needle body 1 resets, it can drive the yarn to move to complete the purling.

[0036] In this utility model, during the purling process, since the tail of the purl reed 2 is a flat segment 23, the triangular groove 25 can be closely attached to the outer wall of the knitting needle body 1, and the first arc segment 21 can be prevented from deforming when the coil is obliquely pulled through the triangular groove 25, reducing the purling error rate. When the knitting needle moves backward, the triangular groove 25 and the support point of the angle between the knitting needle body 1 are used to abut against the latch to ensure that the latch opens smoothly and avoid purling errors.

[0037] As Figure 6 shown, the triangular groove 25 is obliquely arranged on the purl reed 2, and the included angle A between the triangular groove 25 and the upper edge of the purl reed 2 is 60° - 120°, preferably 90°.

[0038] As Figure 6 shown, the included angle B between the two side edges of the triangular groove 25 is 30° - 80°, preferably 60°.

[0039] As one of the embodiments provided by the present utility model, a third arc segment 24 is provided between the second arc segment 22 and the planar segment 23, and the length of the third arc segment 24 accounts for 25%-40% of the total length of the purl spring piece 2, preferably 33%.

[0040] The length of the first arc segment 21 accounts for 15%-30% of the total length of the purl spring piece 2, preferably 23%, the length of the second arc segment 22 accounts for 15%-30% of the total length of the purl spring piece 2, preferably 21%, and the length of the planar segment 23 accounts for 15%-30% of the total length of the purl spring piece 2, preferably 23%.

[0041] As another embodiment provided by the present utility model, as Figure 2 shown, the length of the first arc segment 21 accounts for 15%-30% of the total length of the purl spring piece 2, preferably 23%, the length of the second arc segment 22 accounts for 40%-60% of the total length of the purl spring piece 2, preferably 48%, and the length of the planar segment 23 accounts for 20%-35% of the total length of the purl spring piece 2, preferably 29%.

[0042] The third arc segment 24 is located inside the spring piece mounting groove 11, and the highest point of the second arc segment 22 is not higher than the highest point of the first arc segment 21.

[0043] As Figure 7 shown, the distance C between the top of the first arc segment 21 and the knitting needle body 1 is 0 mm - 4 mm.

[0044] The specific distance between the top of the first arc segment 21 and the knitting needle body 1 depends on the needle type. For the 36-needle type, it is preferably 0.11 mm; for the 35-needle type, it is preferably 0.12 mm; for the 32-needle type, it is preferably 0.15 mm; for the 28-needle type, it is preferably 0.2 mm; for the 24-needle type, it is preferably 0.25 mm; for the 16-needle type, it is preferably 0.7 mm; for the 7-needle type, it is preferably 0.4 mm, 1.08 mm, and 3.2 mm. Other needle types can be fine-tuned according to actual production requirements and will not be listed one by one.

[0045] Those skilled in the art can understand that other similar connection methods can also implement the present utility model. For example, methods such as welding, bonding, or screwing.

[0046] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without a doubt, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
