Abstract

A yarn feeding device of a single-needle double-sided circular knitting machine includes a first yarn threading hole for threading a first yarn, a second yarn threading hole for threading a second yarn, and a shifter for changing the relative positions of the first and second threads, so that when the first and second threads are hooked and pulled by a knitting needle, the positions of the first and second threads in the knitting needle are swapped to let a fabric have two yards on the same surface simultaneously.

Description

Yarn feeding device of single needle double-sided circular knitting machine

A yarn feeding device for a single-needle double-sided circular knitting machine, especially a single-needle double-sided circular knitting machine has a yarn feeding device for changing the position of the first yarn and the second yarn in the knitting needle.

The single-needle double-sided circular knitting machine uses a single knitting needle to hook and pull two yarns at the same time for knitting, so that the two yarns are formed on the upper surface and the lower surface of the fabric. Even if the two yarns use different colors, they can only make the upper surface And the lower surface presents different colors, but it is impossible to make different colors on the same surface. Therefore, how to make the fabric woven by the single needle two-sided circular knitting machine have different color changes on the same surface is related The industry is eager for research and development.

The main purpose of the present invention is to use the yarn feeding device to change the position of two yarns in the knitting needle so that the same surface of the fabric has two yarns at the same time.

To achieve the above object, the yarn feeding device of the present invention has at least a first threading hole for threading the first yarn, a second threading hole for threading the second yarn, and a method for changing the first Displacer of the relative position of the threading hole and the second threading hole, so that when the first yarn and the second yarn are pulled by the knitting needle, the positions of the first yarn and the second yarn in the knitting needle are swapped .

The yarn feeding device of the aforementioned single-needle double-sided circular knitting machine, wherein the yarn feeding device is provided with a bracket, the first threading hole is provided on the surface of the bracket, and the displacement device has a driving member and a displacement member connected to the driving member, the second The threading hole is provided on the surface of the displacement member, and the driving member drives the displacement member to displace, so as to exchange the positions of the first yarn and the second yarn in the knitting needle.

The yarn feeding device of the aforementioned single-needle double-sided circular knitting machine, wherein the displacement device has a driving member and a displacement member connected to the driving member, the first threading hole and the second threading hole are provided on both sides of the displacement member, so that the driving member When the driving displacement member pivots between the first threading hole and the second threading hole, the positions of the first yarn and the second yarn in the knitting needle are swapped.

Please refer to the first to fourth figures, as can be clearly seen from the figure, the yarn feeding device 10 of the present invention is disposed on the side of the knitting cylinder A1 of the circular knitting machine A, and has a support 1 and a support 1 The displacement device 2 is connected, and the support 1 is provided with a first threading hole 11 for the first yarn B to penetrate, and the displacement device 2 has a driving member 21 and a displacement member 22 connected to the driving member 21, and The surface of the displacement member 22 is provided with a second threading hole 221 for the second yarn C to pass through. In this embodiment, the driving member 21 is a solenoid valve, which can push the displacement member 22 to swing.

Please refer to the third to seventh figures, as can be seen from the fourth and sixth figures, when weaving, the driving member 21 drives the displacement member 22 to swing, so that the second threading hole 221 is in the first The upper and lower sides of the threading hole 11 are displaced. Please refer to the fifth and seventh figures. When the second threading hole 221 is located above the first threading hole 11 and below the first threading hole 11,

When the knitting needle A2 hooks the first yarn B and the second yarn C, the positions of the first yarn B and the second yarn C within the knitting needle A2 will swap, so the state of the knitting needle A2 is not changed Next, the first yarn B and the second yarn C can be located on the same surface of the fabric at the same time.

Please refer to the eighth to eleventh figures. It can be clearly seen from the eighth and ninth figures that the yarn feeding device 30 according to the second embodiment of the present invention is connected to the bracket 3 with a displacement device 4 for displacement. The device 4 has a driving member 41, a displacement member 42 and an elastic element 43. The driving member 41 is connected to the bracket 3. The displacement member 42 is provided with a first threading hole 421 for the first yarn B to pass through The second threading hole 422 for the second thread C to pass through, and the displacement member 42 is pivotally connected to the bracket 3 between the first threading hole 421 and the second threading hole 422, and the elastic element 43 is held The displacement member 42 abuts against the driving member 41, so that the driving member 41 pushes the displacement member 42 to pivot between the first threading hole 421 and the second threading hole 422, and the knitting needle A2 pulls the first yarn B and In the case of the second yarn C, the positions of the first yarn B and the second yarn C in the knitting needle A2 will be swapped. Therefore, without changing the knitting needle A2, the first yarn B and the second yarn C can be changed The two yarns C are simultaneously located on the same surface of the fabric.
