Description

Technical Field

[0001] The utility model relates to the technical field of knitting flat knitting machines, in particular to a knitting needle and a spring sheet structure. Background Art

[0002] As is known in the industry, two inclined front needle plates and rear needle plates are symmetrically arranged on a knitting machine, and corresponding needle grooves are respectively arranged on the surfaces of the front and rear needle plates, and knitting needles are installed in each needle groove.

[0003] Current knitting needles generally consist of a needle hook, a needle latch and a needle handle. The needle handle consists of a needle bar and a needle body. The needle hook is located at the front of the needle bar, and the needle latch is hinged at the rear of the needle hook and is used to open and close the needle hook by rotating. The needle body is located at the rear of the needle bar and its width is greater than the width of the needle bar.

[0004] During normal knitting, the knitting needle moves up and down along the needle groove on the needle plate, causing the coil on the knitting needle to slide relative to the knitting needle. When the needle tongue slides to a position corresponding to the needle tongue, the needle tongue is driven to rotate, thereby closing or opening the needle tongue.

[0005] When performing needle transfer knitting, the two knitting needles in the corresponding needle grooves on the front and rear needle plates need to cooperate with each other to realize needle transfer. For example, to transfer the coil on the knitting needle of the front needle plate to the corresponding knitting needle of the rear needle plate, the corresponding knitting needle on the rear needle plate needs to be inserted into the coil of the knitting needle on the above-mentioned front needle plate. In order to ensure reliable insertion, a spring sheet is provided on one side of the needle handle of the knitting needle. When the coil slides to the protrusion of the spring sheet, it is expanded so that the corresponding knitting needle can be inserted from the expanded coil.

DETAILED DESCRIPTION

[0031] like Figure 1-8 As shown, a knitting needle and spring sheet structure comprises a needle body 1, a needle rod 2, a needle hook 3, a needle tongue 4 and a spring sheet 5.

[0032] The needle body 1 is provided with a chamfer 7, and the spring sheet 5 is provided with a chamfer 2 8, so that the knitting needle can enter the cavity in a larger range, avoid the situation where the needle hook 3 cannot enter and cause needle leakage, and improve the success rate of needle transfer.

[0033] A protrusion 201 is provided at the upper end of the needle bar 2, and the height of the protrusion 201 is equal to the thickness of the knitting needle, and the top height of the protrusion 201 is lower than the position of the chamfer 7. This design helps to increase the overall strength of the needle bar 2 and make the operation more stable.

[0034] The protruding portion 201 is provided with a chamfer 2021 to prevent the two knitting needles from colliding when the knitting needles retreat.

[0035] The needle tongue 4 is rotatably connected to the needle hook 3, and the needle tongue 4 rotates with the connection point with the needle hook 3 as the center.

[0036] The front end thickness of the needle hook 3 is smaller than the overall thickness of the knitting needle, so that the needle hook 3 can better enter the cavity 6 when turning the needle.

[0037] The spring sheet 5 is installed in the knitting needle groove 101 opened in the needle body 1 , the flat surface portion 501 of the spring sheet 5 is riveted and fixed to the knitting needle groove 101 , and the narrow portion of the spring sheet 5 extends into the needle rod 2 .

[0038] The planar portion 501 of the spring sheet 5 fits the knitting needle groove 101 , and a cavity 6 for entry through another knitting needle hook is formed between the arched portion 502 of the spring sheet 5 , the needle body 1 and the needle rod 2 , and the thickness of the needle rod 2 is less than the height of the cavity 6 .

[0039] The arched portion 502 is provided with a lower edge 5021, which protrudes from the entire width of the spring sheet 5 to increase the strength of the spring sheet 5, and the protruding portion should not exceed the lower bottom surface of the knitting needle.

[0040] Since chamfers are arranged on the needle body 1 and the spring sheet 5, the closer the lower edge 5021 is to the bottom surface of the needle, the larger the trumpet mouth formed by the two chamfers is, and a larger range is available for the needle hook 3 to enter the cavity 6 when turning the needle.

[0041] The distance between the arched portion 502 and the riveted point is greater than the distance between the arched portion 502 and the narrow tip of the spring sheet 5. When the needle is turned over, when the needle bar 2 penetrates the cavity 6, since the thickness of the needle bar 2 is greater than the size of the cavity 6, the spring sheet 5 will be lifted up with the riveted point as a fulcrum. In order to reduce the reverse elastic force of the lifted spring sheet 5 squeezing the needle bar 2 of another needle, the spring sheet 5 is designed to have a greater distance 54 from the arched portion 502 to the riveted point, so that the reverse elastic force of the lifted spring sheet 5 is lighter, and the squeezing of the other knitting needle is lighter.

[0042] When the coil 9 is connected, the coil 9 slowly moves to the junction of the needle bar 2 and the needle body 1 through the top surface of the needle bar 2, and then completes the knitting, needle transfer and other actions. When the needle is transferred, when the coil 9 moves to the junction of the left needle, the right needle enters the left needle cavity 6, and then slowly moves to the needle body 1. Then the right needle moves up and the left needle retreats. At this time, the right needle hooks the coil 9 and approaches the left needle hook 3 until the coil 9 exits the left needle hook 3 to complete the needle transfer action.

[0043] The spring sheet 5 is provided with a plane 503, and the plane 503 is in contact with the protrusion 201. When the coil 9 is at the junction, the coil 9 is in a tensioned state, which can easily squeeze and deform the arched portion 502, making the cavity 6 smaller and affecting the insertion of the needle hook 3. The plane 503 and the protrusion 201 are provided to reduce the squeezing and deformation of the coil 9 on the spring arched portion 502.

[0044] A support portion 504 is welded on the plane portion 501, and the top surface height of the support portion 504 is less than the height of the highest surface of the spring sheet 5. Since the knitting needle is actuated in the needle groove, the spring sheet height is close to the needle groove spacing under the action of the spring sheet, so that the knitting needle is restricted in the knitting needle groove 101 and is not easy to shake. When turning the needle, the knitting needle needs to be pushed out of the spring sheet 5 outside the knitting needle groove 101, and the knitting needle loses the restriction of the spring sheet 5 in the knitting needle groove 101, and the gap between the needle body 1 and the knitting needle groove 101 increases, which causes the knitting needle to be easily driven by the coil 9 to swing left and right after the coil 9 is hung, affecting the normal turning action. The support portion 504 is welded on the plane portion 501, so that after the spring sheet 5 is pushed out of the knitting needle groove 101 when turning the needle, the support portion 504 still maintains a restrictive relationship with the knitting needle groove 101, so that the knitting needle is not easily driven by the coil 9 to shake left and right, which greatly improves the turning action and ultimately increases the fabric quality.

[0045] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
