Description

Technical Field

[0001] This invention relates to the technical field of textile machinery, and in particular to a knitting needle assembly and a circular knitting machine. Background Technology

[0002] Chinese Patent No. 202310411635.X discloses a novel automatic shearing and loop-cutting jacquard machine, comprising a frame, a lower base plate on the frame, a lower triangular seat on the lower base plate, a lower triangle on the inner side of the lower triangular seat, a cylinder on one side of the lower base plate, a ring on the cylinder, a ring plate on the cylinder, a scissor blade that cooperates with the ring plate, and a scissor triangle ring that cooperates with the scissor blade. A needle plate is disposed above the cylinder, a knitting needle is disposed on the needle plate, an upper triangular seat is disposed above the knitting needle, an upper triangle that cooperates with the knitting needle is mounted on the upper triangular seat, and a yarn feed bar is disposed above the frame above the knitting needle. The end face of the needle plate near the scissor triangle seat is the needle plate opening, and the needle plate opening has a notch for hooking the base yarn.

[0003] Although this type of jacquard machine has a simple structure and low production cost, and can fix the base yarn to make the loop tension stable and improve the finished product, in actual use, in order to complete the loop release, a needle opener needs to be set on the outside of the needle cylinder to open the needle tongue to complete the loop release. This also requires the setting of a triangular control needle opener, thereby reducing the overall work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a knitting needle assembly that facilitates loop removal and simplifies the equipment structure.

[0005] The above-mentioned objective of this invention is achieved through the following technical solutions: A knitting needle assembly includes a needle head and a needle body. The open side of the needle head is rotatably connected to the needle body. A slider is provided between the needle head and the needle body. The slider is slidably disposed between the needle head and the needle body. The top edge of the slider is in contact with the needle head. A first needle foot is provided on the slider, and a second needle foot is provided on the needle body.

[0006] By adopting the above technical solution, the first and second needles are respectively installed in the corresponding tracks of the cam seat. The top edge of the slider abuts against the bottom surface of the needle to keep the needle stable. When the loop needs to be unhooked, the slider moves downward under the drive of the cam seat. At the same time, since the needle loses the support of the slider, the needle tilts backward, and the loop can be unhooked from the needle. Since there is no need to set up a needle opener, the structure is simplified and loop unhooking is convenient.

[0007] In a preferred embodiment, the present invention may be further configured such that the needle includes a hook and a needle body, the hook being disposed on the needle body.

[0008] In a preferred embodiment, the present invention may be further configured such that: the needle body is provided with a needle bar, the needle bar is located on the side of the needle body facing the needle tip opening, and the side of the needle body facing the needle tip opening is rotatably connected to the top of the needle bar.

[0009] By adopting the above technical solution, an area is left between the needle body and the needle tip for the slider to move up and down, and the needle body and the needle tip are connected by the needle bar.

[0010] In a preferred embodiment, the present invention may be further configured such that the needle bar is provided with a limiting member that restricts the needle tip from flipping to the positive side of the needle body.

[0011] By adopting the above technical solution, the limiting component prevents the needle from flipping over the needle body.

[0012] In a preferred embodiment, the present invention can be further configured such that: the top of the slider is disposed on a first slope surface, the first slope surface is inclined from top to bottom in the direction from the back of the knitting needle to the front of the knitting needle, and the bottom edge of the needle tip is disposed as a second slope surface that fits against the first slope surface.

[0013] By adopting the above technical solution, the first and second inclined surfaces can increase the contact area between the slider and the needle, thereby enhancing the stability of the slider's support for the needle.

[0014] In a preferred embodiment, the present invention can be further configured such that the needle body is a right-angled triangular structure, and the two acute vertices of the needle body are respectively connected to the tail of the hook head and the top of the needle shank.

[0015] By adopting the above technical solution, the needle body is designed with a triangular structure, which can enhance the stability of the overall structure of the needle body.

[0016] In a preferred embodiment, the present invention can be further configured such that: the needle bar includes two rods, the limiting member is a sealing edge disposed at the top of the two rods, the sealing edge closes and connects the tops of the two rods, and the connection point of the tops of the two rods is oblique and fits against the oblique edge of the needle body.

[0017] By adopting the above technical solution, since the two rods are closed at the top, the needle body is restricted to a certain range of movement, preventing the needle tip from flipping over the needle body.

[0018] In a preferred embodiment, the invention may be further configured such that the first pin includes two foot pieces, and the pin bar is located between the two foot pieces.

[0019] By adopting the above technical solution, the needle bar can be clamped between the two foot plates, which can maintain the stability of the slider when it moves up and down.

[0020] In a preferred embodiment, the present invention may be further configured such that: a limiting rod is provided on the side of the needle body facing away from the needle tip opening, and the limiting rod extends to the back of the needle tip.

[0021] By adopting the above technical solution, when the slider moves downward, the needle flips backward, and the coil is further disengaged from the needle due to the obstruction of the limiting rod.

[0022] A circular knitting machine includes an upper needle plate and a lower cylinder. The upper needle plate includes a needle cylinder disposed below the upper needle plate and a yarn feeding mechanism. As described above, a knitting needle assembly is arranged around the needle cylinder, and the knitting needle assembly is disposed away from the needle cylinder.

[0023] By adopting the above technical solution, the needle assembly is positioned facing away from the needle cylinder, which allows for a better setting of the yarn feeding mechanism, enabling the needle assembly to better pick up the yarn and improving the efficiency of the needle assembly in picking up yarn.

[0024] In summary, the present invention has at least one of the following beneficial technical effects: 1. It features convenient yarn release, simplified equipment structure, and improved yarn feeding efficiency. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0028] Reference Figure 1 The present invention discloses a circular knitting machine, which includes an upper needle plate and a lower cylinder. The machine includes an upper plate 2, a needle cylinder 3 disposed below the upper plate 2, a yarn feeding mechanism, and a knitting needle assembly 1. The knitting needle assembly 1 is disposed around the needle cylinder 3 and is disposed away from the needle cylinder 3.

[0029] Reference Figure 1-4The knitting needle assembly 1 includes a needle head 11 and a needle body 12. The open side of the needle head 11 is rotatably connected to the needle body 12 via a rotating shaft. A slider 13 is provided between the needle head 11 and the needle body 12. The slider 13 is slidably disposed between the needle head 11 and the needle body 12. An area is provided between the needle head 11 and the needle body 12 for the slider 13 to slide up and down. The top edge of the slider 13 is in contact with the needle head 11. A first needle foot 14 is provided on the slider 13, and a second needle foot 15 is provided on the needle body 12.

[0030] The first needle 14 and the second needle 15 are respectively installed in the corresponding tracks of the cam seat. The top edge of the slider 13 abuts against the bottom surface of the needle 11 to keep the needle 11 stable. When the loop needs to be unhooked after weaving, the slider 13 moves downward under the drive of the cam seat. At the same time, since the needle 11 loses the support of the slider 13, the needle 11 tilts backward, and the loop can be unhooked from the needle 11.

[0031] The needle 11 includes a hook 111 and a needle body 112. The hook 111 is disposed on the needle body 112, and the needle body 112 is configured as a right-angled triangle. The two acute vertices of the needle body 112 are connected to the tail of the hook 111 and the top of the needle shank 121, respectively. The triangular structure of the needle body 112 can enhance the overall stability of the needle body 112.

[0032] The needle body 12 is provided with a needle bar 121, which is located on the side of the needle body 12 facing the opening of the needle tip 11. The needle body 112 is rotatably connected to the top of the needle bar 121 on the side facing the opening of the needle tip 11. The needle bar 121 is provided with a limiting member 123 to prevent the needle tip 11 from flipping to the front side of the needle body 12. The needle bar 121 includes two rod pieces 122. The limiting member 123 is a sealing edge provided at the top of the two rod pieces 122, which seals and connects the top of the two rod pieces 122. The connection point of the top of the two rod pieces 122 is beveled and fits against the bevel of the needle body 112. The first needle foot 14 includes two foot pieces, and the needle bar 121 is located between the two foot pieces.

[0033] Since there is an area between the needle body 12 and the needle tip 11 for the slider 13 to move up and down, the needle body 12 and the needle tip 11 are connected by the needle bar 121, and since the two bars 122 are closed at the top, the needle body 112 is restricted to a certain range of motion, preventing the needle tip 11 from flipping over the needle body 12.

[0034] The top of the slider 13 is set on the first slope surface, which is inclined from top to bottom from the back of the needle to the front of the needle. The bottom edge of the needle 11 is set as a second slope surface that fits into the first slope surface.

[0035] The first and second ramps can increase the contact area between the slider 13 and the needle 11, thereby enhancing the stability of the slider 13 in supporting the needle 11.

[0036] A limiting rod 16 is provided on the side of the needle body 12 facing away from the opening of the needle tip 11, and the limiting rod 16 extends to the back of the needle tip 11.

[0037] As the slider 13 moves downward, the needle 11 flips backward, and the coil is further disengaged from the needle 11 due to the obstruction of the limiting rod 16.

[0038] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
