Description

Technical Field

[0001] The utility model belongs to the technical field of knitting machinery and relates to an enhanced transfer needle. Background Art

[0002] The transfer needle is arranged on the transfer disk body, and the transfer needle cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation during the radial movement. For example, a Chinese patent discloses a durable transfer needle and transfer assembly [application number: 2024208242351], which includes a horizontal needle body and a hook tongue arranged at the front end of the horizontal needle body, and a force-applying structure is also arranged on the horizontal needle body. The rear end of the horizontal needle body is hinged with one end of an L-shaped rear swing rod, and a first hinge hole that can be hinged on the transfer disk is arranged between the two ends of the rear swing rod. The front end of the horizontal needle body is provided with a front swing rod near the hook tongue, and a hinge head is provided at the upper end of the front swing rod. A second C-shaped hinge hole is provided on the hinge head, and a second arc-shaped elastic card body located on the inlet side is provided in the second hinge hole, and a first arc-shaped elastic card body located on the inlet side is provided in the first hinge hole.

[0003] In the above scheme, the front swing arm and the rear swing arm are respectively hinged to the transfer plate through the hinge shafts arranged in the second hinge hole and the first hinge hole, and the first arc-shaped elastic card body and the second arc-shaped elastic card body in the first hinge hole and the second hinge hole can be deformed, and the size of the hinge hole opening can be changed when the hinge shaft enters or moves out of the first hinge hole and the second hinge hole, so as to facilitate the disassembly and assembly between the first hinge hole, the second hinge hole and the hinge shaft. However, the manufacturing process of the first arc-shaped elastic card body and the second arc-shaped elastic card body is difficult and costly, and it is very easy to deform or even break, which will cause the connection of the hinge shaft to be unstable, and in severe cases, the hinge shaft will fall off, resulting in poor stability of the transfer needle during use.

In addition, the manufacturing process difficulty and cost of the second extended arm 13 are relatively low, fatigue deformation is not easy to occur, and it is more suitable for mass production.

[0042] Specifically, combined with Figure 1-Figure 4 As shown, the connecting rod 3 includes a lower rod 32, which is swingably connected to the horizontal needle body 2, and the upper end of the lower rod 32 is connected to the lower end of the inverted L-shaped hook 15.

[0044] Specifically, combined with Figure 1-Figure 4 As shown, a first reinforcing positioning structure 16 is provided on the outer end of the first extended clamp arm 10, and the first reinforcing positioning structure 16 includes a first push rod 17 arranged on the outer end of the first extended clamp arm 10 and gradually inclined inward from the inner end to the outer end, and the distance between the first push rod 17 and the two sides of the first arc-shaped clamping groove 9 is smaller than the diameter of the first arc-shaped clamping groove 9.

[0045] After the first hinge shaft 4 enters the first arc-shaped slot 9, the first push rod 17 on the outer end of the first extended arm 10 supports the bottom end of the first hinge shaft 4, which can ensure that the first hinge shaft 4 will not be detached from the first arc-shaped slot 9, making the connection between the first hinge shaft 4 and the first arc-shaped slot 9 more stable, further enhancing the connection stability of the first hinge shaft 4 in the first arc-shaped slot 9.

[0046] Specifically, combined with Figure 2 and Figure 4 As shown, a first hinge rotation area 18 is formed between the first push rod 17 and the first arc-shaped slot 9, and a bell mouth is provided outside the first hinge rotation area 18.

[0047] A force is applied to the outer end of the first push rod 17 to move outward. When the force on the first push rod 17 exceeds a preset value, it can shift outward, so that the first hinge shaft 4 enters the first hinge shaft rotation area 18 through the trumpet mouth outside the first hinge shaft rotation area 18, and then the first push rod 17 is reset to firmly fix the first hinge shaft 4.

[0048] Specifically, combined with Figure 1 , Figure 2 and Figure 5 As shown, the second hinge axis clamping opening 19 between the second extended clamping arm 13 and the L-shaped swing rod 6 is arranged toward the hook tongue 1 side, and a second reinforcement positioning structure 20 is provided on the outer end of the second extended clamping arm 13 .

[0049] The second hinge shaft entrance 19 between the second extended arm 13 and the L-shaped rocker arm 6 is arranged toward the hook tongue 1, which can facilitate the second hinge shaft 7 to enter the second arc-shaped slot 12.

[0050] Specifically, combined with Figure 1 , Figure 2 and Figure 5 As shown, the second reinforced positioning structure 20 includes a second reinforced arc slot 21 arranged on the inner wall of the outer end of the second extended arm 13, and the second reinforced arc slot 21 is arranged opposite to the second arc slot 12, and the distance between the side of the second reinforced arc slot 21 and the side of the second arc slot 12 is smaller than the diameter of the second arc slot 12 or the diameter of the second reinforced arc slot 21, and a second hinge rotation area 22 is formed between the second reinforced arc slot 21 and the second arc slot 12, and a bell mouth is provided on the outside of the second hinge rotation area 22.

[0051] The second hinge shaft 7 is hinged in the second hinge shaft rotation area 22 formed between the second reinforced arc slot 21 and the second arc slot 12, which can further enhance the connection stability of the second hinge shaft 7 in the second arc slot 12, making the connection between the second hinge shaft 7 and the second arc slot 12 more stable, thereby ensuring that the second hinge shaft 7 will not detach from the second arc slot 12.

[0052] A force is applied to the outer end of the second extended arm 13 to move away from the second arc-shaped slot 12. When the force applied to the second extended arm 13 exceeds a preset value, it can shift around the inner end to move away from the second arc-shaped slot 12, so that the second hinge shaft 7 passes through the trumpet mouth outside the second hinge shaft rotation area 22 and enters the second hinge shaft rotation area 22. Then the second extended arm 13 is reset to firmly fix the second hinge shaft 7.

The width of the narrowed portion 25 is smaller than the width of the card slot 23 to prevent the card body 24 from escaping from the card slot 23. The L-shaped rocker arm 6 and the horizontal needle body 2 are hingedly connected via a hinge shaft 26. The clearance groove 27 on the adjacent surfaces of the hinge between the horizontal needle body 2 and the L-shaped rocker arm 6 plays a clearance role, making the structure more compact.

[0059] The working principle of the utility model is as follows: a force is applied to the outer end of the first extended clamp arm 10 to move outward, and when the force on the first extended clamp arm 10 exceeds a preset value, it can be displaced outward around the inner end, so that the first hinge shaft 4 on the transfer plate body enters the first arc-shaped clamping groove 9, and then the first extended clamp arm 10 is reset, and the first push rod 17 on the outer end of the first extended clamp arm 10 supports the bottom end of the first hinge shaft 4, which can ensure that the first hinge shaft 4 will not be separated from the first arc-shaped clamping groove 9;

[0060] A force is applied to the outer end of the second extended arm 13 to move away from the second arc-shaped slot 12. When the force on the second extended arm 13 exceeds a preset value, it can shift around the inner end to away from the second arc-shaped slot 12. Then the second extended arm 13 is reset, and the second hinge shaft 7 is hinged in the second hinge shaft rotation area 22 formed between the second reinforced arc-shaped slot 21 and the second arc-shaped slot 12, so that the connection between the second hinge shaft 7 and the second arc-shaped slot 12 is more stable, thereby ensuring that the second hinge shaft 7 will not detach from the second arc-shaped slot 12.
