Description

Technical Field

[0001] This utility model relates to flat knitting machine equipment, and more specifically, to a spring plate for a flat knitting machine needle, and also to a flat knitting machine needle having the spring plate. Background Technology

[0002] On the needle plate of a flat knitting machine, multi-weave needles are installed. The needles on the front and rear needle plates work together to realize the knitting action of the flat knitting machine. The knitting needle mainly consists of two parts: the needle bar and the spring plate. There is a gap, or cavity, between the spring plate and the needle bar. The needle hook of the mating needle can be inserted through the cavity, thereby realizing the knitting action.

[0003] During the knitting process, the loops will get caught on the knitting fabric, putting pressure on the surface of the spring sheet. This can easily compress the cavity between the spring sheet and the needle bar, causing the gap in the cavity to narrow. As a result, the hook of the knitting needle cannot be properly inserted between the spring sheet and the needle bar, making it impossible for the two knitting needles to flip the needle and transfer loops, thus affecting the normal operation of the flat knitting machine.

[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 spring sheet for a flat knitting needle and a flat knitting needle.

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

[0007] A spring plate for a flat knitting needle includes a spring plate body mounted on the surface of the needle bar. The spring plate body includes a fixed section, a first curved section, a raised section, and a second curved section arranged sequentially from back to front. The fixed section is fixedly connected to the needle bar. A cavity is formed between the second curved section and the needle bar. The raised section bulges in the direction away from the needle bar and forms a clearance gap with the raised section and the second curved section. A bend is formed between the raised section and the second curved section. The side of the bend facing the needle bar can press against and limit the needle bar. A bending groove is formed on the side of the bend facing away from the needle bar, and the bending groove is used for the yarn to pass around.

[0008] The present invention is further configured such that an arc-shaped transition portion one is formed on the side of the bent portion near the raised section, and an arc-shaped transition portion two is formed on the side of the bent portion near the bent section two, and both the arc-shaped transition portion one and the arc-shaped transition portion two form an arc-shaped smooth transition.

[0009] The present invention is further configured to include a support member, which is located on the side of the spring sheet body facing the needle bar, and a portion of the support member is located within the clearance gap, which can support and limit the raised section.

[0010] The present invention is further configured such that the support member includes an integrally connected connecting part and a supporting part, the connecting part is fixedly connected to the bending section, and the supporting part is located inside the raised section and abuts against the raised section.

[0011] The present invention is further configured such that the connecting part and the supporting part are integrally connected in an L-shaped structure.

[0012] The present invention is further configured such that the curved section has a flat portion facing the needle bar, and the connecting portion of the support member is attached to and fixed to the flat portion.

[0013] The present invention is further configured such that a bending transition portion is formed on one side of the curved section near the raised section, and the bending transition portion bends away from the needle bar direction.

[0014] The present invention is further provided that a protrusion is fixedly connected to the upper side of the raised section, near the bending part.

[0015] This utility model also provides a flat knitting needle, characterized in that it includes a needle bar and a spring plate as described above for a flat knitting needle, wherein a yarn hanging position is formed on the upper side of the needle bar for the yarn to pass through, and the position of the bending groove corresponds to the yarn hanging position.

[0016] The present invention is further configured such that a relief groove is formed on the surface of the needle bar, and a portion of the spring sheet body is embedded and installed in the relief groove.

[0017] In summary, this utility model has the following beneficial effects:

[0018] By providing a raised section on the spring plate body, a bend is formed between the raised section and the second bending section. The side of the bend facing the needle bar can press and limit the movement against the needle bar. A bending groove is formed on the side of the bend facing away from the needle bar, allowing the yarn to pass over it. The bend can directly abut against the surface of the needle bar. When the yarn passes over the bending groove, the bending groove applies pressure to the bend, which is directly transmitted to the needle bar for support. This prevents the pressure of the yarn from squeezing the second bending section and causing the gap of the cavity to shrink, thus maintaining the gap of the cavity.

[0019] A support member is provided between the spring sheet body and the needle bar. Part of the support member can extend into the clearance gap to support and limit the raised section. With the support of the support member, the stability of the raised section of the spring sheet body can be maintained, and the clearance gap inside the raised section can be maintained.

Detailed Implementation

[0027] 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.

[0028] This embodiment discloses a spring sheet for a flat knitting needle, referring to... Figure 6 As shown, when used in conjunction with needle bar 300, they can form a flat knitting needle.

[0029] In this embodiment, the spring sheet of the flat knitting needle includes a spring sheet body 100, which is mounted on the surface of the needle bar 300. The spring sheet body 100 includes a fixed section 1, a first bending section 2, a raised section 3 and a second bending section 4 arranged sequentially from back to front. Each section of the spring sheet body 100 is integrally bent from the same metal sheet to form a multi-segment bending structure with elasticity.

[0030] The fixed section 1 is fixedly connected to the needle bar 300, serving as the rear end support of the spring plate body 100. The parts of the spring plate body 100 near the front end can be elastically bent away from the needle bar 300. A cavity 41 is formed between the bent section 4 and the needle bar 300, allowing the hook of another set of knitting needles to be inserted, thus enabling normal knitting operations.

[0031] The raised section 3 bulges in the direction away from the needle bar 300, forming a clearance gap 31 between the raised section 3 and the needle bar 300. A bent transition section 22 is formed on the side of the curved section 2 near the raised section 3, bending in the direction away from the needle bar 300, allowing the raised section 3 to be relatively far away from the needle bar 300, thus enabling the raised section 3 to form a raised structure facing away from the needle bar 300. The height of the raised section 3 is close to the height of the raised section 4; ideally, the heights should be the same.

[0032] A bend 5 is formed between the raised section 3 and the second curved section 4. The side of the bend 5 facing the needle bar 300 can press against and limit the needle bar 300. Furthermore, a bending groove 51 is formed on the side of the bend 5 facing away from the needle bar 300, allowing the yarn 400 to pass over it. Since the bend 5 can directly abut against the surface of the needle bar 300, when the yarn 400 passes over the bending groove 51, the bending groove 51 will apply pressure to the bend 5. This pressure can be directly transmitted to the needle bar 300 to provide support, preventing the pressure of the yarn 400 from squeezing the second curved section 4 and causing the gap of the cavity 41 to become smaller, thus maintaining the gap of the cavity 41.

[0033] Furthermore, since the two sides of the bending part 5 are the bending part 5 and the second bending section 4 respectively, both the bending part 5 and the second bending section 4 protrude in the direction away from the needle bar 300 and have a certain protrusion height, the bending groove 51 at the bending part 5 can have a certain depth to increase the stability of the yarn 400 passing around.

[0034] Reference Figures 3-5 As shown, an arc-shaped transition section 52 is formed on the side of the bent portion 5 near the raised section 3, and an arc-shaped transition section 53 is formed on the side of the bent portion 5 near the curved section 4. Both the arc-shaped transition section 52 and the arc-shaped transition section 53 form a smooth arc transition. Through the smooth arc transition, the needle hook inserted between the needle bar 300 and the spring plate body 100 can be guided, ensuring that the needle hook can slide smoothly when passing through the bent portion 5.

[0035] Furthermore, in this embodiment, the spring sheet of the flat knitting needle also includes a support member 200. The support member 200 is located on the side of the spring sheet body 100 facing the needle bar 300. A portion of the support member 200 can extend into the clearance gap 31, providing support and limiting for the raised section 3. With the support of the support member 200, the stability of the raised section 3 of the spring sheet body 100 can be maintained, and the clearance gap 31 inside the raised section 3 can be maintained.

[0036] Reference Figures 3-5As shown, the support member 200 includes an integrally connected connecting part 7 and a support part 8, which have an L-shaped structure. The connecting part 7 is fixedly connected to the curved section 2, and one side of the connecting part 7 extends toward the raised section 3 and into the inner clearance gap 31 of the raised section 3. The support part 8 is connected to the connecting part 7 and is located inside the raised section 3, so that it can abut against the raised section 3.

[0037] Furthermore, the curved section 2 has a flat portion 21 facing the needle bar 300, and the connecting portion 7 of the support member 200 is attached to and fixed to the flat portion 21. When the spring sheet is installed with the needle bar 300, the connecting portion 7 of the support member 200 can press against and fit against the needle bar 300, thereby achieving overall positioning and support of the spring sheet and maintaining the structural stability of the spring sheet.

[0038] Reference Figure 6 As shown, a protrusion 6 is fixedly connected to the upper side of the raised section 3 and near the bending section 5. The protrusion 6 protrudes from the upper side of the spring sheet body 100 and can limit the winding yarn 400, so that the yarn 400 can be stably restricted at the bending groove 51.

[0039] This embodiment also discloses a flat knitting needle, including a needle bar 300 and a spring sheet that also includes the flat knitting needle in the above embodiment. A yarn hanging position 301 for the yarn 400 to pass over is formed on the upper side of the needle bar 300, and the position of the bending groove 51 corresponds to the yarn hanging position 301.

[0040] When the yarn 400 passes around the knitting needle, the yarn 400 is limited by the hanging position 301 and the protrusion 6 on the upper side of the needle bar 300, ensuring that the yarn 400 can pass around stably and restricting the yarn 400 at the bending groove 51 to maintain the gap of the cavity 41 inside the spring plate body 100, so that the matching needle hook can be smoothly inserted into the cavity 41 and maintain the stable operation of the flat knitting machine.

[0041] Additionally, refer to Figure 1 , Figure 2 As shown, a relief groove 302 is provided on the surface of the needle bar 300. A portion of the spring sheet body 100 is embedded and installed in the relief groove 302. The relief groove 302 can achieve relief in the thickness direction, so that the overall knitting has a thinner thickness.

[0042] 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.
