The above technical problem of the present invention can be solved by the following technical solutions: a circular knitting machine comprises a rack and a knitting mechanism arranged on the rack, wherein the knitting mechanism comprises a needle cylinder which is rotatably arranged on the rack and a plurality of knitting needles which are vertically arranged on the needle cylinder in a sliding manner, a mouth is arranged at the end part of the needle cylinder, and one side of each knitting needle abuts against the mouth when the knitting needles move in the needle cylinder; and one side of the top of the knitting needle, which is close to the nozzle, is provided with a abdicating groove, so that the top of the knitting needle is eccentric to the other side.

In the structure, when the knitting needle drives the yarn to move in the needle cylinder, the yarn is positioned in a gap formed between the abdicating groove of the knitting needle and the nozzle, so that the yarn is prevented from being clamped or broken.

The knitting needle comprises a needle body, a hook integrally arranged at the top of the needle body and a latch hinged on the needle body and located below the hook, and the lower edge of the abdicating groove is located below the hinged position of the latch and the needle body.

The needle separating device is further arranged on the rack, and the cutting edge of the needle separating knife is positioned on the motion track of the latch of the knitting needle, so that the closed latch can be opened by the cutting edge when the knitting needle moves.

Furthermore, a needle separating knife is arranged on the rack, the tail part of the needle separating knife is arranged on the rack above the needle cylinder through a bolt, and the angle and the position of the needle separating knife are adjustable.

Furthermore, a waist-shaped hole is formed in the tail of the needle separating knife, the bolt penetrates through the waist-shaped hole to fix the needle separating knife on the rack, the angle of the needle separating knife can be adjusted by loosening the bolt, and the position of the needle separating knife can be adjusted by adjusting the position of the bolt in the waist-shaped hole.

Compared with the prior art, the utility model, its beneficial effect lies in:

1. the utility model discloses a set up the groove of stepping down on the knitting needle, make the knitting needle eccentric to one side for there is the clearance between the top of knitting needle and the mouth, the knitting needle drives the yarn and returns when contracting yarn and lie in the clearance, thereby has avoided the yarn to be blocked and blocked even the card absolutely, reduces to shut down because of the equipment that the yarn fracture caused, has promoted work efficiency.

2. The utility model discloses a setting up and dividing the needle sword, realized the automation of the latch of knitting needle and opened, its simple structure, the adjustment is convenient to be convenient for maintenance and change.

In the figure: 1. a frame; 2. a needle cylinder; 3. a nozzle; 4. the needle comprises a knitting needle 41, a needle body 42, a hook 43, a needle tongue 44, an abdicating groove 45 and the lower edge of the abdicating groove; 6. a needle separating knife 61, a waist-shaped hole 62 and a bolt.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): a circular knitting machine is disclosed, as shown in figures 1-6, comprising a frame 1, a knitting mechanism is arranged on the frame 1, the knitting mechanism comprises a needle cylinder 2 which is rotatably arranged on the frame 1 and a plurality of knitting needles 4 which are arranged on the needle cylinder 2, the knitting needles 4 can vertically slide along the needle cylinder 2, a mouth 3 is arranged at the end part of the needle cylinder 2, and the left side of the knitting needles 4 abuts against the side wall of the mouth 3 when moving in the needle cylinder 2.

In this embodiment, the knitting needle 4 includes a needle body 41, a hook 42 integrally disposed on the top of the needle body 41, and a latch 43 hinged to the needle body 41 and located below the hook 42, wherein the end where the hook 42 and the latch 43 are located is eccentrically disposed toward the right side, that is, an abdicating groove 44 is disposed on the left side of the knitting needle 4, and a lower edge 45 of the abdicating groove is located below the hinge of the latch 43 and the needle body 41, so that a gap 5 is formed between the top where the hook 42 and the latch 43 of the knitting needle 4 are located and the sidewall of the nozzle 3, and when the knitting needle 4 drives the yarn to retract into the nozzle 3, the yarn on the left side of the knitting needle 4 can be located in the gap 5 between the abdicating groove 44 and the nozzle 3, thereby preventing the yarn from being blocked.
