The horizontal position of the knitting thread is adjusted so as to efficiently and accurately adjust the tightness of the knitting thread, thereby improving the knitting quality and efficiency of the knitting machine. Secondly, two columnar connecting shafts 6 are fixedly connected to the inner wall of the movable frame 5, and the outer surfaces of the two connecting shafts 6 are rotatably connected with disc-shaped wire wheels 7, so that the knitting thread can pass through the two wire wheels 7. The knitting thread is limited and guided by the two wire wheels 7 to avoid the knitting thread from being offset and affecting the normal knitting work. The rotating design of the two wire wheels 7 can rotate during the knitting thread unwinding process, thereby reducing the wear on the knitting thread, avoiding the breakage of the knitting thread, and ensuring the normal operation of the knitting machine.

[0021] Reference Figure 2 A columnar limiting column 8 is fixedly connected to the upper surface of the bottom plate 1 and the inner top surface of the first support plate 2, and the outer surface of the limiting column 8 slides relatively with the movable plate 4. Secondly, a stud 9 is rotatably connected to the upper surface of the bottom plate 1 and the inner top surface of the second support plate 3. The outer surface of the stud 9 is screwed together with the movable plate 4 through a ball screw, and the upper end of the stud 9 passes through the second support plate 3 to its upper surface and is fixedly connected to the output end of the motor so that the stud 9 can be driven to rotate by the motor, thereby driving the movable plate 4 to slide up and down under the action of the ball screw. At the same time, the sliding of the movable plate 4 is limited by the limiting column 8 to avoid deviation, so as to accurately adjust the height of the knitting line.

[0022] Reference Figure 3A rack 10 is fixedly connected to the upper surface of the movable plate 4, and a gear 11 is rotatably connected to the side surface of the movable frame 5 through a rotating shaft, and the outer surface of the gear 11 can be arc-shapedly meshed with the upper surface of the rack 10, and one end of the rotating shaft passes through the movable frame 5 to its side surface, and is fixedly connected to the output end of the motor, so that the rotating shaft is driven by the motor to rotate, thereby driving the gear 11 to rotate, so that the movable frame 5 is driven to slide left and right on the upper surface of the bottom plate 1 under the meshing action of the outer surface of the gear 11 and the upper surface of the rack 10, thereby adjusting the horizontal position of the knitting thread; secondly, a T-shaped groove 12 is provided on the upper surface of the movable plate 4 at the side surface of the rack 10, and a T-shaped block-shaped slider 13 is fixedly connected to the lower surface of the movable frame 5, and the slider 13 slides relative to the inner wall of the groove 12, so that the sliding of the movable frame 5 is limited by the sliding of the slider 13 on the inner wall of the groove 12 to ensure the smoothness of the sliding.

[0023] The implementation principle of a knitting track adjustment device for a knitting machine in the embodiment of the present application is as follows: the knitting thread is passed through the gap between the two wire wheels 7, and the knitting thread is limited and guided by the two wire wheels 7 to prevent the knitting thread from being deviated. When adjustment is needed, the stud 9 is driven to rotate by the motor, thereby driving the movable plate 4 to slide up and down under the action of the ball screw, and at the same time, the sliding of the movable plate 4 is limited by the limiting column 8 to prevent deviation, thereby driving the wire wheel 7 to slide up and down, so as to accurately adjust the height of the knitting thread, so as to adjust the tightness of the knitting thread, and secondly, the rotating shaft is driven to rotate by the motor, thereby driving the gear 11 to rotate, thereby driving the movable frame 5 to slide left and right on the upper surface of the bottom plate 1 under the meshing action of the outer surface of the gear 11 and the upper surface of the rack 10, thereby adjusting the horizontal position of the wire wheel 7, thereby adjusting the horizontal position of the knitting thread, thereby realizing multi-directional adjustment of the knitting thread, so as to efficiently and accurately adjust the tightness of the knitting thread, thereby improving the knitting quality and efficiency of the knitting machine.
