Description

Technical Field

[0001] The present invention relates to flat knitting machine equipment, and more specifically, to a needle system for a flat knitting machine, and further to a flat knitting machine having the needle system. Background Technology

[0002] In a flat knitting machine, a needle plate provides support, and several inserts are mounted on the needle plate, forming needle grooves between adjacent inserts. A knitting needle is embedded in each needle groove, with its underside supported by the upper surface of the needle plate. The needle can slide and adjust along the needle groove, thus controlling its movement. The needle is installed in the needle groove with a clearance fit. After the needle is embedded, gaps form on both sides of the needle, causing it to easily wobble and bounce laterally. This affects the stability of the needle's movement and the tightness of the knit.

[0003] To improve the stability of knitting needles, the current practice is usually to increase the precision between the width of the knitting needle and the width of the needle groove, so as to reduce the gap range after the knitting needle is installed, thereby reducing the lateral runout of the knitting needle. However, if the gap between the knitting needle and the needle groove is too small after installation, it may affect the sliding of the knitting needle, and it may also affect the normal assembly of the knitting needle due to local twisting.

[0004] Therefore, a new solution is needed to address the stability issue of the knitting needle within the needle groove. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a knitting needle system for a flat knitting machine and a flat knitting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a knitting needle system for a flat knitting machine, comprising inserts, needles, and a linkage needle bar. The inserts are mounted parallel to each other on a needle plate, and a needle groove is formed between two adjacent inserts. A needle and a linkage needle bar are embedded in each needle groove. The two inner sidewalls of the needle groove correspond to the first and second surfaces of two adjacent inserts, respectively. The two sides of the needle are a third and a fourth surface, respectively. The third surface presses against the first surface on one side of the needle groove. A spring plate is installed on the fourth surface of the needle near the needle hook end, and the spring plate presses against the second surface on the other side of the needle groove. The knitting needle has an elastic abutment near its tail end, and a connecting section is formed between the middle section of the knitting needle and the tail end. The thickness of the connecting section is less than that of the middle section of the knitting needle, and a groove is formed on the side of the connecting section facing the second surface. A linkage groove is provided on the upper edge of the knitting needle, and a linkage block is integrally connected to the linkage needle rod. The linkage block is embedded in the linkage groove, enabling the knitting needle and the linkage needle rod to move together. A pad is integrally connected to the lower side of the linkage needle rod. The pad is embedded in the groove of the connecting section, and the two sides of the pad abut against the groove and the second surface of the needle groove, respectively.

[0007] The invention is further configured such that the needle tail section elastically abuts against the inner wall of one side of the needle groove; the needle tail section bends toward the second surface, so as to elastically abut against the second surface.

[0008] The invention is further configured such that a relief groove is provided on the second surface, and a portion of the knitting needle is embedded in the relief groove; a first pressing surface and a second pressing surface are respectively formed on both sides of the pad, the first pressing surface abuts against the groove of the connecting section, and the second pressing surface abuts against the relief groove on the second surface; the second pressing surface of the pad protrudes from the linkage needle bar and is partially embedded in the relief groove.

[0009] The invention is further configured such that a notch is provided on the upper side of the relief groove, and the notch extends to the upper edge of the insert.

[0010] The present invention is further configured such that the width of the needle groove is L, the width of the middle section of the knitting needle is d1, the width of the groove of the knitting needle is d2, the width of the pad is d3, and the lateral depth of the relief groove is a; the range of d1 is (0.8L, 0.9L), and the range of d2+d3 is (0.90(L+a), 1.0(L+a)).

[0011] The invention is further configured such that the lower side of the pad forms a lower end; the position of the lower end is lower than the lower side of the knitting needle; the pad includes a straight section on the upper side and an inclined curved section on the lower side, the lower side of the inclined curved section is elastically curved toward the knitting needle direction; the pressing surface is a vertical plane corresponding to the straight section and an inclined slope corresponding to the inclined curved section.

[0012] The present invention is further configured such that the linkage needle rod can swing up and down around the linkage block, and has an upper swing position and a lower swing position. When the linkage needle rod is in the lower swing position, the straight section of the pad extends into the groove, and the outer pressing surface of the straight section abuts against the surface of the groove. When the linkage needle rod is in the upper swing position, a portion of the inclined curved section of the pad extends into the groove, and the outer pressing surface of the inclined curved section abuts against the surface of the groove.

[0013] The present invention is further configured such that a protrusion is fixedly connected to the upper side of the linkage needle rod; when the linkage needle rod is in the upper swing position, the protrusion protrudes from the upper side of the needle groove between adjacent inserts; when the linkage needle rod is in the lower swing position, the protrusion is recessed into the needle groove between adjacent inserts.

[0014] The invention is further configured such that the insert is embedded in the upper surface of the needle plate, the lower side of the knitting needle is in contact with the upper surface of the needle plate, and is guided by the upper surface of the needle plate.

[0015] The present invention also provides a flat knitting machine, including the needle system of the flat knitting machine as described above.

[0016] In summary, the present invention has the following beneficial effects:

[0017] By maintaining a normal gap between the width of the knitting needle and the needle groove, there is no need to deliberately reduce the fit between the two. When the knitting needle is installed in the needle groove, three support points can be formed along the length of the knitting needle: the spring plate, the needle tail section, and the pad, thus maintaining the flatness and stability of the knitting needle. Under the lateral action of the knitting needle, an elastic effect is formed, which can always keep the third surface of the knitting needle pressed against the first surface on one side of the needle groove, reducing the lateral shaking and deviation of the knitting needle.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This embodiment discloses a needle system for a flat knitting machine, referring to... Figures 1-9 As shown, the design of the knitting needle 2, the linkage needle bar 3 at the end of the knitting needle 2, and the inserts 1 on both sides of the knitting needle 2 in the flat knitting machine is carried out.

[0036] Reference Figures 1-4 As shown, the knitting needle system of the flat knitting machine includes inserts 1, knitting needles 2, and linkage needle bars 3. Several inserts 1 are provided. Slots for installing the inserts 1 are pre-cut in the needle plate (not shown in the figure), and the inserts 1 are embedded into the upper surface of the needle plate. The inserts 1 are distributed in a parallel and equidistant manner. A needle groove 10 is formed between two adjacent inserts 1, and the knitting needles 2 and linkage needle bars 3 are embedded and installed within the needle groove 10.

[0037] The insert 1 is embedded in the upper surface of the needle plate. The two sides of the needle groove 10 are limited by the inserts 1 on both sides, and the lower part of the needle groove 10 is limited by the upper surface of the side needle plate. After the knitting needle 2 is embedded in the needle groove 10, the lower side of the knitting needle 2 abuts against the upper surface of the needle plate and is supported and guided by the upper surface of the needle plate.

[0038] The two sides of the insert 1 form a first surface 11 and a second surface 12 respectively. After the inserts 1 are arranged in parallel, the two inner sidewalls of the needle groove 10 correspond to the first surface 11 and the second surface 12 of two adjacent inserts 1 respectively.

[0039] The knitting needle 2 has a third surface 21 and a fourth surface 22 on its two sides. After installation, the third surface 21 of the knitting needle 2 abuts against the first surface 11 on one side of the needle groove 10. Through this mutual contact, the position of the knitting needle 2 can be limited, allowing it to maintain smooth and stable sliding movement. The knitting needle 2 abuts against the upper surface of the needle plate through its lower side, thus limiting its vertical position; and the third surface 21 of the knitting needle 2 abuts against the first surface 11 on one side of the needle groove 10, thus limiting its horizontal position.

[0040] Reference Figure 5 , Figure 6 As shown, a spring plate 23 is installed on the fourth surface 22 of the knitting needle 2 near the needle hook end. The spring plate 23 can elastically abut against the second surface 12 on the other side of the needle groove 10. Under the elastic action of the spring plate 23, the third surface 21 of the knitting needle 2 can always be kept pressed against the first surface 11 on one side of the needle groove 10, reducing the lateral swaying and deviation of the knitting needle 2.

[0041] A needle tail section 24 is formed near the needle tail of the knitting needle 2. The needle tail section 24 elastically abuts against the inner wall of one side of the needle groove 10, thereby forming a lateral elastic pressure at the needle tail end and maintaining the lateral positional stability of the needle tail end. See details. Figure 6 As shown, the needle tail section 24 bends towards the second surface 12, elastically resisting it. Under the elastic action of the needle tail section 24, it generates a reaction force on the knitting needle 2 towards the third surface 21, so that at the needle tail end, the third surface 21 of the knitting needle 2 also presses against and adheres to the first surface 11 on one side of the needle groove 10. Through the combined action of the spring sheet 23 and the needle tail section 24, the lateral position of the knitting needle 2 can be kept stable, and the third surface 21 of the knitting needle 2 and the first surface 11 on one side of the needle groove 10 can be in a flat knitting fit and positioning position.

[0042] Furthermore, the middle section 20 is formed in the middle of the knitting needle 2, which is the main body section of the knitting needle 2. A connecting section 26 is formed between the middle section 20 and the needle tail section 24, and a groove 261 is formed on the side of the connecting section 26 facing the second surface 12. The thickness of the connecting section 26 is less than that of the middle section 20 of the knitting needle 2, making the connecting section 26 thinner. The knitting needle 2 is easier to bend at the connecting section 26. During processing, the connecting section 26 can be bent at the groove 261, so that the needle tail section 24 can form a mutually inclined and bent state with the middle section 20 of the knitting needle 2. After the knitting needle 2 is inserted into the needle groove 10, a pressure force can be formed between the first surface 11 and the second surface 12 on both sides of the needle groove 10, which can maintain the lateral elastic positioning of the knitting needle 2 and keep the third surface 21 of the knitting needle 2 stably attached to the first surface 11 on one side of the needle groove 10.

[0043] Reference Figures 7-9 As shown, a linkage groove 25 is provided on the upper edge of the knitting needle 2, and a linkage block 31 is integrally connected to the linkage needle rod 3. The linkage block 31 is embedded in the linkage groove 25, which enables the knitting needle 2 and the linkage groove 25 to be linked together.

[0044] Reference Figure 9 As shown, a pad 32 is integrally connected to the lower side of the linkage needle bar 3. The position of the pad 32 corresponds to the position of the connecting section 26 of the knitting needle 2. After the linkage needle bar 3 and the knitting needle 2 are assembled together, the pad 32 of the linkage needle bar 3 can be embedded in the groove 261 of the connecting section 26. The pad 32 can form a support at the connecting section 26 of the knitting needle 2, that is, it can form a support on one side of the fourth surface 22 of the needle bar 3.

[0045] When the pad 32 is embedded into the groove 261 of the connecting section 26 and assembled with the needle 2 into the needle groove 10, both sides of the pad 32 will abut against the groove 261 and the second surface 12 of the needle groove 10, respectively. By abutting against the second surface 12 of the needle groove 10 and against the groove 261 of the needle bar 3, a force can be applied to the needle 2 toward the third surface 21, and the third surface 21 of the needle 2 can be stably attached to the first surface 11 on one side of the needle groove 10. Therefore, along the length of the needle 2, three support points can be formed: the spring plate 23, the needle tail section 24, and the pad 32, thereby maintaining the flatness and stability of the needle 2.

[0046] Reference Figure 2 , Figure 4As shown, a relief groove 121 is provided on the second surface 12 of the insert 1. The knitting needle 2 is installed between the two inserts 1. Part of the knitting needle 2 can be embedded in the relief groove 121. In the transverse width direction, the relief groove 121 can reduce the thickness of the insert 1 and the knitting needle 2 stacked together, thereby allowing more knitting needles 2 to be installed within a single width range, which can increase the arrangement density of the knitting needles 2 and thus increase the weaving density of the fabric.

[0047] When the pad 32 is inserted into the groove 261, the pad 32 will also be embedded in the relief groove 121. Specifically, a first abutment surface 321 and a second abutment surface 322 are formed on both sides of the pad 32. The first abutment surface 321 abuts against the surface of the groove 261 of the connecting section 26, and the second abutment surface 322 is embedded in the relief groove 121 and abuts against the inner surface of the relief groove 121, thereby forming a limit at the relief groove 121 of the second surface 12.

[0048] Reference Figure 8 The pressing surface 322 of the pad 32 protrudes from the linkage pin 3, and the protruding part is the part that is embedded in the relief groove 121.

[0049] A notch 122 is provided on the upper side of the relief groove 121. The lower side of the notch 122 extends to the relief groove 121 and communicates with it. The upper side of the notch 122 extends to the upper edge of the insert 1, forming a through notch on the upper side. Moreover, the width of the notch 122 is adapted to the width of the pad 32. The width of the pad 32 is slightly smaller. When the linkage needle bar 3 is installed, the position of the pad 32 is aligned with the position of the notch 122. The pad 32 slides down along the notch 122 and can enter the relief groove 121, thereby realizing the installation of the linkage needle bar 3.

[0050] The present invention also provides a flat knitting machine, including the needle assembly as described above, which is capable of maintaining the stability of the needle 2 within the needle groove 10.

[0051] Example 2

[0052] This embodiment discloses a knitting needle system for a flat knitting machine, based on Embodiment 1, and further referring to... Figure 10 Please provide a detailed explanation.

[0053] Reference Figure 10 As shown, the width of the needle groove 10 is L, which is the distance between the two inserts 1 on both sides of the needle groove 10; the width of the middle section 20 of the needle 2 is d1, which is the width of the main body section of the needle 2; the width of the groove 261 of the needle 2 is d2; the width of the pad 32 is d3; and the lateral depth of the clearance groove 121 is a.

[0054] In this embodiment, the width of the main body segment of the needle 2 is the width d1 of the main body segment of the needle 2, and d1 ranges from (0.8L to 0.9L). This width is slightly smaller than the width L of the needle groove 10, allowing the needle 2 to smoothly embed into the needle groove 10 between the two inserts 1. Since there is theoretically a gap between 0.1L and 0.2L, the needle 2 can slide smoothly. Under the elastic action of the spring plate 23 and the needle tail segment 24, the needle 2 can always be in contact with the surface of one side of the insert 1. This gap range will not actually affect the downward movement of the needle 2, thus maintaining the stability of the needle 2 and reducing lateral slippage.

[0055] Further, in this embodiment, the value of d2+d3 is the sum of the width d2 of the groove 261 of the needle 2 and the width d3 of the pad 32; the value of L+a is the sum of the width of the needle groove 10 and the depth of the relief groove 121. The range of d2+d3 is (0.90(L+a), 1.0(L+a)). By inserting the pad 32 into the groove 261 of the needle 2, the tightness of the fit between the needle 2 and the needle groove 10 can be improved, a tight-fitting limiting point can be supported at the groove 261 of the needle 2, and the needle 2 can also slide normally.

[0056] Example 3

[0057] This embodiment discloses a knitting needle system for a flat knitting machine. Based on the above embodiment, further referring to... Figure 11-15 Please provide a detailed explanation.

[0058] Reference Figure 11 , Figure 12 As shown, a lower end portion 323 is formed on the underside of the pad 32; the position of the lower end portion 323 is lower than the underside of the knitting needle 2.

[0059] The linkage needle bar 3 and the knitting needle 2 can slide and move together via the linkage block 31. Furthermore, the linkage needle bar 3 can swing up and down around the linkage block 31, and has upper and lower swing positions. A protrusion 35 is fixedly connected to the upper side of the linkage needle bar 3. In the upper swing position, the protrusion 35 protrudes above the needle groove 10 between adjacent inserts 1; in the lower swing position, the protrusion 35 is recessed into the needle groove 10 between adjacent inserts 1. Depending on whether the protrusion 35 protrudes from the needle groove 10, and in conjunction with the corresponding knitting needle triangle, the desired movement of the knitting needle 2 can be achieved.

[0060] Reference Figure 15As shown, in this embodiment, the pad 32 has an inclined curved structure, not a purely vertical state. Specifically, the pad 32 includes an upper straight section 33 and a lower inclined curved section 34, which are integrally connected. The straight section 33 has a vertical planar structure, and the inclined curved section 34 is connected to the lower side of the straight section 33. The lower side of the inclined curved section 34 is elastically curved towards the knitting needle 2. The pressure surface 321 corresponds to the vertical plane at the straight section 33, and the pressure surface 321 corresponds to the inclined slope at the inclined curved section 34.

[0061] During the up-and-down swing of the linkage needle bar 3 around the linkage block 31, the straight section 33 and the inclined curved section 34 of the pad block 32 are embedded into the groove 261 at different positions. Since the pressure surface 321 is not a single vertical plane, it can form two states during the swing. Specifically, when the linkage needle bar 3 is in the downward swing position, the straight section 33 of the pad block 32 extends into the groove 261, and the pressure surface 321 on the outer side of the straight section 33 abuts against the surface of the groove 261. At this time, the protrusion 35 of the linkage needle bar 3 is embedded in the needle groove 10 and is not affected by the linkage of the knitting needle triangle. It only performs ordinary knitting action, and the knitting needle 2 can slide smoothly.

[0062] When the linkage needle bar 3 is in the upper sway position, part of the inclined curved section 34 of the pad 32 extends into the groove 261, and the outer pressing surface 321 of the inclined curved section 34 abuts against the surface of the groove 261. Since the inclined curved section 34 protrudes towards the groove 261, in this state, the inclined curved section 34 of the pad 32 can generate a greater elastic pressing force on the groove 261 of the knitting needle 2, and can press the connecting section 26 of the knitting needle 2 tightly against the first surface 11 of the needle groove 10. At this time, the protrusion 35 of the linkage needle bar 3 protrudes out of the needle groove 10, and the knitting needle 2 needs to cooperate with the linkage effect of the knitting needle triangle. At this time, the knitting needle 2 will need to perform a specific lifting and lowering action. At this time, the knitting needle 2 can be effectively kept in a state of action that is always close to the first surface 11 of the needle groove 10, ensuring the running stability of the special lifting and lowering activities of the knitting 2, and avoiding the knitting needle 2 from lateral swaying, which would affect the stability of the knitting.

[0063] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
