[0028] Please see Figure 1-5Based on specific embodiment 1, the multi-degree-of-freedom adjustment component 6 further includes a horizontal plate 604 disposed at the bottom of the fixed plate 1, a vertical plate 605 fixedly connected to the top of the horizontal plate 604, a second motor 606 movably connected to one side of the vertical plate 605, the output end of the second motor 606 being movably connected to the vertical plate 605 via a bearing, a threaded rod 607 fixedly connected to the output end of the second motor 606, the side of the threaded rod 607 away from the second motor 606 being movably connected to the vertical plate 605 via a bearing, a threaded sleeve 608 threadedly connected to the surface of the threaded rod 607, the top of the threaded sleeve 608 being fixedly connected to the gear plate 602, a movable frame 609 disposed at the top of the threaded rod 607, and a movable plate 610 fixedly connected to the surface of the movable frame 609. The movable frame 609 consists of two connecting plates and a movable rod. The bottom of the connecting plates is fixedly connected to the horizontal plate 604, and the movable rod is movably connected to the connecting plates via a bearing. The gear 601 and the movable plate 610 are both fixedly connected to the surface of the movable rod, and the top of the movable plate 610 is open to the horizontal plate 604. The protective box is detachably connected to the fixed plate 1 via bolts.

A groove adapted to the slider is opened on the top of the horizontal plate 604. An installation plate is provided at the bottom of the horizontal plate 604. The bottom of the protective box is fixedly connected to the installation plate. An installation hole is opened on the top of the installation plate. The protective box is fixedly connected to the top of the installation plate. The first motor 603 is located inside the protective box. The bottom of the first motor 603 is fixedly connected to the bottom of the protective box. The output end of the first motor 603 is fixedly connected to the horizontal plate 604. The top of the protective box is in contact with the horizontal plate 604. A disc is fixedly connected to the surface of the protective box. A support rod is provided on the top of the disc. A movable block is fixedly connected to the bottom of the support rod. The top of the support rod is fixedly connected to the horizontal plate 604. An annular movable groove adapted to the movable block is opened on the top of the disc, which can ensure that the horizontal plate 604 and all the structures on the horizontal plate 604 rotate more smoothly. A bracket is fixedly connected to one side of the second motor 606. The bracket is fixedly connected to the vertical plate 605.

[0029] The working principle of this utility model is as follows: First, the entire mechanism is fixedly connected to the designated position of the knitting machine through the mounting holes on the mounting plate to ensure the stability of the mechanism.

[0030] The operation of the first cylinder 2 drives the connecting frame 502 and all its structures to move up and down, thereby achieving precise adjustment of the cylinder's position and ensuring that the cylinder can be accurately aligned with the fabric during the weaving process.

[0031] According to production needs, the second cylinder 501 drives the small-diameter cylinder 4 to move inside the large-diameter cylinder 3, thereby adjusting the cylinder diameter. This variable diameter design allows the knitting machine to adapt to the production of fabrics of different specifications, improving the machine's versatility.

[0032] When multi-angle adjustment of the syringe is required, the second motor 606 first drives the threaded rod 607 to rotate, which in turn drives the toothed plate 602 to move via the threaded sleeve 608. The movement of the toothed plate 602 drives the movable plate 610 and all its structures to rotate as a whole through the gear 601 and the movable frame 609, thereby achieving horizontal rotation adjustment of the syringe. Next, the first motor 603 drives the horizontal plate 604 and all its structures to rotate as a whole, thereby achieving vertical angle adjustment of the syringe. This multi-degree-of-freedom adjustment mechanism allows the syringe to be flexibly adjusted in multiple directions, meeting the production needs of complex fabrics.

[0033] During adjustment, the sliding connection between the slider and the horizontal plate 604 ensures smooth operation of the entire mechanism, reduces vibration and noise, and improves the machine's stability and service life. Simultaneously, the design of the disc and support rod ensures smoother rotation of the horizontal plate 604 and all its components, further enhancing the machine's operational stability. This enables multi-degree-of-freedom adjustment and variable diameter design of the needle cylinder, greatly improving the adaptability and production efficiency of the knitting machine and meeting the modern textile industry's demand for high-precision, highly flexible production equipment.
