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 a perspective view of a hanger tooth 4d of the present invention, the hanger tooth 4d having a hanger tooth body 41 and a transfer portion 42 at the head (one end contacting a fabric loop) of the hanger tooth body 41. The hanger body 41 is formed in an elongated thin plate shape, and the transfer portion 42 is bent downward deviating from the axis of the hanger body 41, and preferably, the transfer portion 42 is formed in an arc shape tapered from the end of the hanger body 41 and having a pointed tip. The tail part (the end far away from the fabric coil) of the hanging tooth main body 41 is provided with a hanging tooth protrusion 411, the hanging tooth protrusion 411 is clamped on a transfer disc of the fabric transfer device, the hanging tooth protrusion 411 is pushed and pulled, the hanging tooth can move inwards and outwards in the radial direction, and the hanging tooth can also move up and down to transfer the fabric coil.

The pick body 41 has a thickness such that a recess can be formed in the head of the pick body 41, i.e., the transfer portion 42, i.e., the outer side (left side in the drawing) of the transfer portion 42, and the pick recess 43 is formed to receive a slit tooth of a fabric sewing apparatus, the function and general structure of which are well known to those skilled in the art and will not be described herein.

At the end of the tooth hanging groove 43, a chamfer 44 is provided on the outside of the groove wall, which facilitates the smooth transfer of the coil from bottom to top to the position of the transfer part 42, so that the coil does not hang a wire and is not stuck (see fig. 3). The tail part (the end far away from the fabric coil) of the hanging tooth main body 41 is provided with a hanging tooth protrusion 411, the hanging tooth protrusion 411 is clamped on a transfer disc of the fabric transfer device, the hanging tooth protrusion 411 is pushed and pulled, the hanging tooth can move inwards and outwards in the radial direction, and the hanging tooth can also move up and down to transfer the fabric coil.

Fig. 2 shows the structure of the tooth protector 4 c. The tooth protecting sheet 4c is used for being matched with the hanging teeth 4 d. The tooth protector 4c has a tooth protector main body 45, a tooth protector holding portion 46 extending downward from the front end (the end contacting the loops of the fabric) of the tooth protector main body 45, and a tooth protector projection 451 provided on the lower side of the rear end (the end distant from the loops of the fabric) of the tooth protector main body 45. This tooth guard projection 451 is snapped onto the transfer disc of the fabric transfer device, pushing and pulling the tooth guard projection 451 can move the hanger teeth radially inwards and inwards, but also can move up and down to transfer the fabric coil. A tooth protector chamfered portion 47 is formed at the junction between the tooth protector main body 45 and the tooth protector sandwiching portion 46. The guard blade body 45 has a plurality of guard blade grooves 452 on the underside thereof for engaging a transfer disc of a fabric transfer device. In use, the suture needle 4a is inserted into the hanging tooth groove 43 of the hanging tooth 4 d.

The operation of the inventive hanger is described below with reference to fig. 3-14. The utility model is described below by way of example for socks, but the utility model can also be applied to other fabrics.

As shown in fig. 3, 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. 4, the sinker 201 in fig. 3 is removed and the transfer device is moved over the knitting needle 1 so that the knitting needle 1 is positioned under the gap formed between the two tooth-protecting pieces 4 c.

As shown in FIG. 5, the tooth-protecting pieces 4c are moved downward to allow the knitting needle 1 to pass through a gap formed between the two tooth-protecting pieces 4 c. The tooth 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. 6, the tooth protector 4c is moved radially outward, disengaging from the knitting needle 1.

In fig. 7, the latch 4d is moved radially inwards until the tip of the knitting needle 1 is located in the latch groove 43 formed by the latch 4d, the latch groove 43 being located between the body and the latch of the knitting needle 1.

In fig. 8, the tooth guard 4c is moved radially inward so that the knitting needle 1 is between the gap formed between the two tooth guards 4 c. At this stage, the tooth-protecting piece 4c is positioned radially further outwards with respect to the position of the knitting needle 1 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. 9, 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. 10, the fabric 8 has carried the latch of the hosiery knitting needle 1 upwards, so that the latch is closed and thus the opening of the hosiery knitting needle 1 is closed.

In fig. 11, the latch of the knitting needle 1 is engaged with the outside of the latch 4d (radially outside about the axis of the footwear inverting tube 3), and the cloth 8 can be smoothly transferred from the knitting needle 1 to the transfer portion 42 of the latch 4 d.

In figure 12 the transfer device is moved upwards, at which point the fabric 8 has been transferred to the knitting needle 1 and the lower side of the fabric 8 is dragged by the tooth-protection flaps 4c, so that the sock can move upwards.

In fig. 13, the needle-removing dial 2 is moved downwards.

In fig. 14, the sinker 201 is moved radially inwards, in cooperation with the take-off dial 2 and the knitting needles 1, ready to knit the next fabric.

The above-described embodiments are merely preferred embodiments of the present invention, and general changes and substitutions by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
