The winding motor 151 operates to drive the winding shaft 152 and the winding sleeve 153 to rotate synchronously, thereby rolling the knitted fabric onto the winding sleeve 153. Before the knitted fabric is rolled up onto the winding sleeve 153, the knitted fabric passes through the leveling roller group 162, and the knitted fabric is leveled by the leveling roller group 162, which helps to ensure the flatness of the knitted fabric when it is rolled up onto the winding sleeve 153.

[0048] The implementation principle of the embodiment of the present application is: when knitting knitted fabrics, the operator places the yarn storage drum 92 wrapped with yarn on the placement rack 91, and allows the yarn on the yarn storage drum 92 to pass through the corresponding needle rack 5 under the guidance of the yarn guide 93 and then enter the inside of the knitting mechanism 3.

[0049] When it is necessary to adjust the tension of the provided yarn, the motor 81 runs, driving the driving gear 82 to rotate, thereby driving the inner ring gear 83 to rotate synchronously under the meshing action; when the inner ring gear 83 rotates, it drives the driven gear 84 to rotate synchronously under the meshing action, thereby driving the threaded rod 85 to move along its own axial direction. During the movement, the threaded rod 85 drives the creel 7 to move synchronously, which helps to adjust the height of the creel 7, helps to adjust the tension of the provided yarn, and ensures the yarn supply effect.

[0050] The knitting mechanism 3 is used to knit a plurality of yarns into knitted fabrics. When the angle of the needle holder 5 needs to be adjusted, the micro motor 63 is started to drive the first gear 64 to rotate, thereby driving the second gear 65 and the mounting shaft 61 to rotate synchronously under the meshing action, and the mounting shaft 61 drives the needle holder 5 to rotate synchronously while rotating, thereby facilitating the automatic adjustment of the angle of the needle holder 5 relative to the knitting needle seat 4, facilitating the convenience of adjusting the angle of the needle holder 5, and further facilitating the accuracy of adjusting the angle of the needle holder 5, and avoiding the situation of picking and breaking of the textile thread as much as possible, thereby ensuring the production quality of the knitted fabrics.

[0051] When the mounting shaft 61 drives the needle holder 5 to rotate, the bottom end of the needle holder 5 moves along the movable track 62, thereby helping to improve the stability of the needle holder 5 during rotation, helping to improve the accuracy of the rotation position of the needle holder 5, and further improving the angle adjustment accuracy of the needle holder 5.

[0052] When the knitted fabric is wound up, the rotary cylinder 171 operates to drive the rotary disk 172 to rotate, thereby driving the winding frame 13 to rotate synchronously with the rotation of the knitted fabric, which is convenient for the subsequent winding operation. The winding motor 151 operates to drive the winding shaft 152 and the winding sleeve 153 to rotate synchronously, thereby winding the knitted fabric onto the winding sleeve 153. Before the knitted fabric is wound onto the winding sleeve 153, the knitted fabric passes through the flattening roller group 162, and the flattening roller group 162 is used to flatten the knitted fabric, which helps to ensure the flatness of the knitted fabric when it is wound onto the winding sleeve 153.
