Description

Technical Field

[0001] This utility model relates to a computerized flat knitting machine, and more specifically, to a flat knitting machine needle. Background Technology

[0002] The computerized flat knitting machine needle, as the core knitting component, forms a planar cam structure through a cam mechanism. After the needle foot is inserted into the groove, it is driven by a moving cam to rise and fall regularly within the needle groove. During the rise, the old loop exits the needle hook and hangs on the needle bar; during the fall, the needle hook catches the new yarn to form a new loop, while the old loop exits. The new and old loops are connected in series to form the basic knot of the fabric.

[0003] A spring plate is installed on the side of the knitting needle. One end of the spring plate is fixedly connected to the needle bar, while the other end can elastically deform relative to the needle. In the stationary state, a needle insertion gap is formed between the spring plate and the needle bar, allowing a matching needle to be inserted for knitting. When rising, the old loop is dislodged from the hook and hooked onto the needle bar. The yarn of the loop presses against the spring plate on the side of the needle bar, causing the needle insertion gap between the spring plate and the needle bar to narrow, affecting the insertion of subsequent needles and even the normal knitting action between the needles.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flat knitting needle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flat knitting needle includes a needle bar and a spring plate. The spring plate includes a fixed section, a connecting section, a first abutment section, a raised section, and a second abutment section, all integrally connected. The fixed section is fixedly connected to the needle bar. The connecting section connects the fixed section and the first abutment section. The raised section connects the first abutment section and the second abutment section. The first abutment section and the second abutment section abut against the needle bar. The raised section protrudes in a direction away from the needle bar, forming a needle insertion gap between the raised section and the needle bar.

[0008] The present invention is further configured such that a first thread hanging position is formed on the upper side of the needle bar, and a second thread hanging position is formed between the first abutting section and the raised section of the spring sheet. The first thread hanging position and the second thread hanging position can overlap each other for the yarn to pass around.

[0009] The present invention is further configured such that the connecting segment is arc-shaped and bulges outward toward the needle bar.

[0010] The present invention is further configured such that a transition portion one is formed at the connection between the raised section and the abutting section one, and a transition portion two is formed at the connection between the raised section and the abutting section two.

[0011] The present invention is further configured such that, from the direction of the first abutment section to the second abutment section, the first transition section bends away from the needle bar direction, the second transition section bends towards the needle bar direction, and the bending amplitude of the first transition section is greater than that of the second transition section.

[0012] The present invention is further configured such that the needle bar includes a middle section, a needle hook end and a needle tail end, and a relief groove is formed on the side of the middle section, and at least a portion of the spring sheet is embedded in the relief groove.

[0013] The present invention is further configured such that a second relief groove is formed on the side of the hook end, and the second abutting section of the spring sheet is embedded in and pressed against the second relief groove.

[0014] The present invention is further configured such that the fixing segment is fitted and fixed to the side of the needle bar and embedded in the relief groove.

[0015] The present invention is further configured such that the abutting section one forms a plane on the side facing the needle bar, and the side of the needle bar forms an abutting surface that is adapted to abut the abutting section one.

[0016] The present invention is further configured such that a protrusion is integrally connected to the upper side of the first abutment section, and an L-shaped corner is formed between the protrusion and the raised section, forming the second hanging position.

[0017] The present invention is further configured such that a positioning groove is formed at the abutting surface of the needle bar; a positioning protrusion is formed at one abutting section of the spring sheet, the positioning protrusion and the positioning groove are adapted to each other, the abutting section abuts against the abutting surface, and the positioning protrusion is embedded in the positioning groove.

[0018] In summary, this utility model has the following beneficial effects:

[0019] The spring plate of the knitting needle is supported by a fixed section and extends towards the needle hook end of the needle bar. The first and second abutting sections abut against the needle bar, supporting the position of the raised section. The raised section bulges away from the needle bar, forming a needle insertion gap between the raised section and the needle bar, where a matching knitting needle can be inserted. Stable support is provided on both sides of the raised section, thus maintaining a stable needle insertion gap and allowing for smooth insertion of the matching knitting needle. At one abutting section, the elastic plate can press and limit the position of the spring plate and the needle bar. When the yarn passes around the second hanging position, the pressure of the yarn will be concentrated at the abutting section. The first abutting section abuts against the needle bar and directly bears the force, avoiding pressure from the yarn on the raised section and preventing the needle insertion gap inside the raised section from narrowing and affecting needle insertion.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses a flat knitting needle, suitable for use on computerized flat knitting machines, see reference. Figures 1-6 As shown, it includes a needle bar 81 and a spring plate 82. The spring plate 82 is installed on the side of the needle bar 81, with one end fixedly connected to the needle bar 81 and the other end being able to bend elastically, so that the knitting needle can be inserted into the needle gap 83 to achieve knitting.

[0030] Reference Figures 3-6As shown, the spring sheet 82 includes an integrally connected fixed section 821, a connecting section 822, a first abutment section 823, a raised section 824, and a second abutment section 825. The connecting section 822 connects the fixed section 821 and the first abutment section 823, and the raised section 824 connects the first abutment section 823 and the second abutment section 825. The segments of the spring sheet 82 can be connected sequentially to form an integral structure capable of elastic bending.

[0031] The fixed section 821 is fixedly connected to the needle bar 81, forming a connection between the spring plate 82 and the needle bar 81. Specifically, the connection and fixation can be achieved by bonding or riveting.

[0032] The spring plate 82 is supported by the fixed section 821 and extends toward the needle hook end 811 of the needle bar 81. The first abutment section 823 and the second abutment section 825 abut against the needle bar 81, respectively, and can support the position of the raised section 824. The raised section 824 protrudes in the direction away from the needle bar 81, forming a needle insertion gap 83 between the raised section 824 and the needle bar 81, where a matching knitting needle can be inserted.

[0033] A first thread-hanging position 813 is formed on the upper side of the needle bar 81. A second thread-hanging position 827 is formed between the first abutment section 823 and the raised section 824 of the spring sheet 82. The first thread-hanging position 813 and the second thread-hanging position 827 can overlap each other for the yarn 80 to pass around. At the first thread-hanging position 813, the needle bar 81 forms an L-shaped notch to limit the passing of the yarn 80. A protrusion 8231 is integrally connected to the upper side of the first abutment section 823. An L-shaped corner is formed between the protrusion 8231 and the raised section 824, forming the second thread-hanging position 826. The positions of the first thread-hanging position 813 and the second thread-hanging position 827 are opposite to each other, and they can jointly limit the yarn 80.

[0034] At the first abutment section 823, the position of the spring plate 82 and the needle bar 81 can be pressed and limited. When the yarn 80 passes around the second hanging position 827, the pressure of the yarn 80 will be concentrated at the first abutment section 823. The first abutment section 823 and the needle bar 81 directly bear the force, avoiding the yarn 80 from compressing the raised section 824 and preventing the needle insertion gap 83 inside the raised section 824 from narrowing and affecting the insertion of the knitting needle.

[0035] Reference Figure 5 , Figure 6 As shown, the abutment section 823 forms a flat surface on the side facing the needle bar 81, and the side of the needle bar 81 forms an abutment surface 816 that is adapted to abut the abutment section 823. The abutment section 823 abuts against the abutment surface 816, forming a flat pressure support and maintaining the structural stability of the spring sheet 82 in the pressure state.

[0036] Reference Figure 5 , Figure 6As shown, the connecting section 822 is curved in an arc shape and bulges outward from the needle bar 81. After the arc-shaped connecting section 822 approaches the plane of the needle bar 81, both ends of the connecting section 822 can abut against the needle bar 81. At the fixing section 821 of the spring sheet 82, it is fixedly connected to the needle bar 81, and the abutting section 823 can elastically abut against the needle bar 81, thereby ensuring that the abutting section 823 abuts against the needle bar 81, and thus maintaining the stability of the needle insertion gap 83 inside the raised section 824.

[0037] Furthermore, referring to Figure 6 As shown, a transition section 8241 is formed at the connection between the raised section 824 and the first abutment section 823, and a transition section 8242 is formed at the connection between the raised section 824 and the second abutment section 825. Both transition sections 8241 and 8242 have a curved, arc-shaped structure. From the first abutment section 823 to the second abutment section 825, transition section 8241 bends away from the needle bar 81, while transition section 8242 bends towards the needle bar 81, and the bending amplitude of transition section 8241 is greater than that of transition section 8242. Due to the large bending float at transition section 8241, when the yarn 80 passes around, it can be guided by transition section 8241, so that the position of the yarn 80 passing around can be as close as possible to the first abutment section 823, avoiding inward pressure on the raised section 824, thereby maintaining the stability of the needle gap 83 inside the raised section 824.

[0038] Reference Figure 1 , Figure 2 , Figure 5 As shown, the needle bar 81 includes a middle section 810, a needle hook end 811, and a needle tail end 12. The needle hook end 811 is integrally connected with a hook part 83 and a needle tongue 84 is installed thereon. The needle tail end 12 cooperates with the long needle 9 to achieve mutual linkage.

[0039] In order to reduce the overall thickness of the needle bar 81, a relief groove 814 can be opened on the side of the needle bar 81, and at least part of the spring sheet 82 can be embedded in the relief groove 814, thereby reducing the overall thickness of the needle bar 81 and the spring sheet 82 after they are stacked.

[0040] Specifically, referring to 11, 13, and 14, a relief groove 814 is formed on the side of the middle section 810, and at least a portion of the spring sheet 82 is embedded in the relief groove 814. The fixing section 821 is fixed to the side of the needle bar 81 and embedded in the relief groove 815. The thickness of the fixing section 821 is less than the depth of the relief groove 814, thus allowing the fixing section 821 to be completely embedded in the relief groove 814. Other parts of the spring sheet 82 may undergo elastic deformation, and after elastic deformation, it may bend away from the relief groove 814.

[0041] In addition, a second relief groove 815 is formed on the side of the needle hook end 811. The second relief groove 815 is located on the side of the needle hook end 811 of the needle bar 81, and the second abutment section 825 of the spring sheet 82 is embedded and pressed into the second relief groove 815. The second relief groove 815 can accommodate the second abutment section 825, reduce the thickness of the overlap between the second abutment section 825 and the needle hook end 811 of the needle bar 81, and can also position the second abutment section 825 of the spring sheet 82, thereby improving the stability of the spring sheet 82 during elastic deformation and avoiding the undesirable situation of the second abutment section 825 of the spring sheet 82 shifting.

[0042] Furthermore, referring to Figure 7 As shown, to improve the stability of the pressing position between the needle bar 81 and the spring plate 82, a positioning groove 91 is formed in the needle bar 81, corresponding to the position of the abutment surface 816; a positioning protrusion 92 is integrally formed on the side of the spring plate 82 facing the needle bar 81, corresponding to the position of the abutment section 823, and the positioning protrusion 92 can be formed by stamping. The positions of the positioning protrusion 92 and the positioning groove 91 are mutually adapted, and the shape of the positioning protrusion 92 is slightly smaller than that of the positioning groove 91, so that the positioning protrusion 92 can be smoothly embedded into the positioning groove 91. Through the mutual positioning and cooperation of the positioning protrusion 92 and the positioning groove 91, the abutment section 823 of the spring plate 82 and the needle bar 81 can have a certain anti-displacement ability, especially resisting the offset force along the width direction of the needle bar 81, which can improve the positional accuracy of the spring plate 82 during the elastic reset process.

[0043] In addition, two inclined transition sections 921 are formed on both sides of the positioning protrusion 92, which can guide the passing needle hook and avoid obstructing or jamming the movement of the needle hook.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
