Detailed Description

Embodiments of the present invention will now be described with reference to the drawings, wherein like parts are designated by like reference numerals. The embodiments described below and the technical features of the embodiments may be combined with each other without conflict.

Fig. 1 shows the structure of the needle guard 4 c. The needle guard 4c is used in cooperation with the

transfer needles

4a, 4 b. The needle guard 4c has a needle guard main body 45, and a needle guard holding portion 46 extends downward from the front end (one end contacting the stitches of the fabric) of the needle guard main body 45. Preferably, the needle guard clamping portion 46 extends vertically downward.

The needle guard projection 451 is provided on the lower side of the rear end (end distant from the loop of the fabric) of the needle guard main body 45. The needle guard projection 451 is engaged to a transfer tray of a fabric transfer apparatus, and pushing and pulling the needle guard projection 451 can move a transfer needle radially inward and inward, and also can move up and down to perform transfer of a fabric loop. A needle guard beveling portion 47 is formed at the junction between the needle guard main body 45 and the needle guard holding portion 46.

The lower side of the needle guard body 45 has a plurality of needle guard grooves 452 for engagement with a transfer disc of a fabric transfer device. In use, the

sewing needles

4a and 4b are inserted between the two needle guard pieces 4c and positioned in the gap formed by the needle guard piece holders 46 of the two needle guard pieces.

Fig. 2 shows a perspective view of the transfer needle 4a having a transfer needle body 41 with a transfer portion 42 at the head (one end contacting the loop of fabric) of the transfer needle body 41. The transfer needle body 41 is an elongated thin sheet, the transfer portion 42 is curved and offset from the axis of the transfer needle body 41, and preferably, the transfer portion 42 is arc-shaped, tapering from the end of the transfer needle body 41 and pointed at the tip. The transfer needle body 41 has a transfer needle protrusion 411 at a rear portion (an end away from the fabric loop), and the transfer needle protrusion 411 is engaged with a transfer tray of the fabric transfer device, pushes and pulls the transfer needle protrusion 411, and can move the transfer needle inward and inward in the radial direction, and can also move up and down to perform the transfer of the fabric loop.

Fig. 3 shows a perspective view of the transfer pin 4b, which is symmetrical to the transfer pin 4a in shape, in contrast to the transfer pin 4 a. In use, a pair of

transfer needles

4a, 4b are required to cooperate. Specifically, the

transfer pins

4a and 4b are bonded together. The transfer needle body 41 is made into a sheet shape, so that the two bodies are jointed together, the volume is reduced, and the transfer needle is more environment-friendly.

Fig. 4 shows a state diagram of the

transfer needles

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

transfer needles

4a, 4b are fitted together, while the respective transfer portions 42 form a recess, a transfer needle recess 43, which transfer needle recess 43 is intended to receive the slot teeth of a fabric sewing device, the function and general structure of which are well known to the person skilled in the art and will not be described here.

Fig. 5 shows another embodiment of the transfer pin, and unlike the first embodiment, the transfer pin body 41 has a thickness such that a groove, i.e., a transfer pin groove 43, can be formed at the head of the transfer pin body 41. The transfer needle recesses 43 are also used to accommodate the slit teeth. Preferably, the transfer needle groove 43 is asymmetrical with a notch at the end of the groove so that the tip of the knitting needle 1 can slide more smoothly into the transfer needle groove 43 (see fig. 6). The transfer needle body 41 has a transfer needle protrusion 411 at a rear portion (an end away from the fabric loop), and the transfer needle protrusion 411 is engaged with a transfer tray of the fabric transfer device, pushes and pulls the transfer needle protrusion 411, and can move the transfer needle inward and inward in the radial direction, and can also move up and down to perform the transfer of the fabric loop.

The working process of the needle guard of the present invention is described with reference to fig. 6-17. The invention is described below with reference to socks as an example, but the invention can also be applied to other fabrics.

As shown in fig. 6, after the sock is woven to the last turn, the fabric 8 is inside the tube 3 of the hosiery knitting machine, with the loops of the fabric 8 under the latch of the hosiery knitting needle 1.

As shown in fig. 7, the sock support piece 201 of fig. 6 is removed and the transfer device is moved over the knitting needle 1 so that the knitting needle 1 is positioned below the gap formed between the two needle guard pieces 4 c.

As shown in FIG. 8, the needle protecting piece 4c is moved downward to allow the knitting needle 1 to pass through the gap formed between the two needle protecting pieces 4 c. The needle guard 4c continues downwards until the fabric 8 is pressed against the needle-off dial 2. This is to ensure that the fabric 8 is under the latch of the hosiery knitting needle 1 in preparation for successful stitch transfer.

In fig. 9, the needle guard 4c is moved radially outward, disengaging from the knitting needle 1.

In fig. 10, the

transfer needles

4a, 4b are moved radially inwards until the tip of the knitting needle 1 is located in the transfer needle groove 43 formed by the

transfer needles

4a, 4b, the transfer needle groove 43 being located between the body and the latch of the knitting needle 1.

In fig. 11, the needle guard 4c is moved radially inward so that the knitting needle 1 is between the gap formed between the two needle guards 4 c. At this stage, the position of the needle-guard 4c with respect to the position of the knitting needles 1 is radially more external than in the stage shown in figure 8, so as to avoid blocking the upward movement of the fabric 8 in the following stage.

In fig. 12, the needle-off dial 2 is moved upwards, pushing the fabric 8 upwards, and the fabric 8 will correspondingly move upwards along the hosiery knitting needle 1.

In fig. 13, the fabric 8 has carried the latch of the knitting needle 1 upwards, so that the latch is closed and the opening of the knitting needle 1 is closed.

In fig. 14, the latch of the knitting needle 1 is caught on the outer side of the transfer needle 4a (the radially outer side centered on the axis of the footwear inverting tube 3), so that the cloth 8 can be smoothly transferred from the knitting needle 1 to the transfer portion 42 of the transfer needle 4 a.

In fig. 15, the transfer device is moved upwards, at which time the fabric 8 has been transferred to the knitting needles 1 and the lower side of the fabric 8 is dragged by the needle-guard 4c, so that the sock can move upwards.

In fig. 16, the needle-removing dial 2 is moved downwards.

In fig. 17, the sinker 201 moves radially inwards, cooperating with the take-off dial 2 and the knitting needles 1, ready to knit the next fabric.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the ordinary changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
