Detailed ways

The embodiments of the present invention are described below with reference to the drawings, in which the same components are denoted by the same reference numerals. In the case of no conflict, the following embodiments and technical features in the embodiments can be combined with each other.

FIG. 1 shows a perspective view of the transfer needle 4a of the present invention. The transfer needle has a transfer needle body 41, and the head of the transfer needle body 41 (the end contacting the fabric loop) has a transfer portion 42. The transfer needle body 41 is in the shape of a thin and elongated sheet, and the transfer part 42 is curved and deviates from the axis of the transfer needle body 41. Preferably, the transfer part 42 is arc-shaped, tapering from the end of the transfer needle body 41, and the end is pointed. . The tail (the end far from the fabric loop) of the transfer needle body 41 has a transfer needle protrusion 411, which is engaged with the transfer plate of the fabric transfer device, and pushes and pulls the transfer needle protrusion 411 to transfer The needle moves inward and forward in the radial direction, and can also move up and down to transfer fabric loops.

Figure 2 shows a three-dimensional view of the transfer needle 4b of the present invention. The difference from the transfer needle 4a is that its shape is symmetrical to the transfer needle 4a. When in use, a pair of

transfer pins

4a and 4b are required to be used together. Specifically, the

transfer pins

4a and 4b are attached together. The transfer pin main body 41 is made into a sheet shape, which is also to reduce the volume when the two are attached together, which is more environmentally friendly.

Figure 3 shows the state diagram of the

transfer pins

4a, 4b when in use. The transfer needle bodies 41 of the

transfer needles

4a and 4b are attached together, and the respective transfer parts 42 form a groove, a transfer needle groove 43, which is used to accommodate the slit teeth and stitches of the fabric sewing device. The function and general structure of the mouth teeth are well known to those skilled in the art and will not be described here.

Figure 4 shows another embodiment of the transfer needle of the present invention. The difference from the first embodiment is that the transfer needle body 41 has a certain thickness, so that a groove can be opened on the head of the transfer needle body 41, that is, the transfer needle Needle groove 43. The transfer pin groove 43 is also used to accommodate the slit teeth. Preferably, the transfer needle groove 43 is asymmetrical, with a gap at the end of the groove, so that the needle of the hosiery needle 1 can slide into the transfer needle groove 43 more smoothly (see FIG. 6). The tail (the end far from the fabric loop) of the transfer needle body 41 has a transfer needle protrusion 411, which is engaged with the transfer plate of the fabric transfer device, and pushes and pulls the transfer needle protrusion 411 to transfer The needle moves inward and forward in the radial direction, and can also move up and down to transfer fabric loops.

Figure 5 shows the structure of the needle guard 4c. The needle guard 4c is used in conjunction with the

transfer needles

4a and 4b. The needle guard 4c has a needle guard body 45, the front end of the needle guard body 45 (the end contacting the loop of the fabric) extends downwardly with a needle guard clamping portion 46, and the rear end of the needle guard body 45 (away from the loop of the fabric) A needle guard protrusion 451 is provided on the underside of one end). The needle guard protrusion 451 is clamped to the transfer plate of the fabric transfer device. Pushing and pulling the needle guard protrusion 451 can move the transfer needle inward and forward in the radial direction, and can also move up and down for fabric looping. Transfer. A needle guard chamfer 47 is formed at the joint between the needle guard body 45 and the needle guard clamping portion 46. The needle guard body 45 has a plurality of needle guard grooves 452 on the lower side to be combined with the transfer disc of the fabric transfer device. In use, the

suture needles

4a, 4b are inserted between the two needle guards 4c, and are located in the gap formed by the needle guard clamping portions 46 of the two needle guards.

Hereinafter, a schematic diagram of the working process of the transfer needle of the present invention will be described with reference to FIGS. 6-17. The following uses socks as an example to describe the present invention, but the present invention can also be applied to other fabrics.

As shown in Fig. 6, when the hosiery machine knits to the last loop, the fabric 8 is in the hosiery tube 3 of the hosiery machine, and the loop of the fabric 8 is under the tongue of the hosiery needle 1.

As shown in Fig. 7, the sock support sheet 201 in Fig. 6 is removed, and the transfer device is moved above the hosiery needle 1 so that the hosiery needle 1 is located below the gap formed between the two needle guards 4c.

As shown in Fig. 8, the needle guard 4c is moved downward so that the hosiery needle 1 passes through the gap formed between the two needle guards 4c. The needle guard 4c continues downwards until the fabric 8 is pressed on the needle release disk 2. This is to ensure that the fabric 8 is under the tongue of the hosiery needle 1 in preparation for the successful transfer of stitches.

In FIG. 9, the needle guard 4c is moved radially outward to separate from the hosiery needle 1.

In Figure 10, the transfer needles 4a, 4b are moved radially inward until the needle of the hosiery needle 1 is located in the transfer needle groove 43 formed by the transfer needles 4a, 4b, and the transfer needle groove 43 is located on the hosiery needle 1. Between the main body and the needle tongue.

In Figure 11, the needle guard 4c is moved radially inward, so that the hosiery needle 1 is between the gap formed between the two needle guards 4c. At this stage, the position of the needle guard 4c relative to the position of the hosiery needle 1 is more radially outward than the stage shown in FIG. 8 to avoid blocking the upward movement of the fabric 8 in the next stage.

In Fig. 12, if the needle removal disk 2 is moved upward, the fabric 8 is pushed upward, and the fabric 8 will move upward along the hosiery needle 1 accordingly.

In Fig. 13, the fabric 8 has driven the needle tongue of the hosiery needle 1 upward, so that the needle tongue is closed, so that the opening of the hosiery needle 1 is closed.

In Figure 14, the needle tongue of the hosiery needle 1 is placed on the outer side of the transfer needle 4a (the radially outer side centered on the shaft of the sock tube 3), so that the fabric 8 can be smoothly transferred from the hosiery needle 1 to the transfer needle. Needle 4a on the transfer part 42.

In Fig. 15, the transfer device is moved upwards. At this time, the fabric 8 has been transferred to the hosiery needle 1, and the needle guard 4c is dragged under the fabric 8, so the socks can move upward.

In Fig. 16, the ejecting disc 2 is moved downward.

In Fig. 17, the green sheet 201 moves radially inward and cooperates with the de-pinning disc 2 and the hosiery needle 1 to prepare for knitting the next fabric.

The above-mentioned embodiments are only preferred specific implementations of the present utility model, and the usual changes and replacements made by those skilled in the art within the scope of the technical solution of the present utility model shall be included in the protection scope of the present utility model.
