[0031] Figure 1 and Figure 2 The yarn feeding structure for a knitting machine shown includes a yarn feeder 1, a yarn spool 2 mounted on one side surface of the yarn feeder 1, a guide wheel assembly 3 provided on the surface of the yarn feeder 1, and an adjustment device 4 provided on the surface of the yarn feeder 1. The adjustment device 4 adjusts the tension of the yarn on the yarn feeder 1 by means of rollers 43 and auxiliary wheels 46. A cleaning component 5 is provided on one side of the mounting frame 41.

[0032] Figure 1 , Figure 2 and Figure 3 The adjustment device 4 shown includes a mounting frame 41, which is mounted on the surface of the pay-off frame 1 via a connecting rod 42. A roller 43 is rotatably mounted on one side of the mounting frame 41. A mounting rod 44 is fixedly connected to the inner wall of the mounting frame 41. A rotating frame 45 is rotatably mounted on the arc surface of the mounting rod 44. An auxiliary device is rotatably mounted at one end of the rotating frame 45. A servo motor 48 is fixedly connected to one side of the mounting frame 41. Gears 47 are respectively mounted on the output end of the servo motor 48 and one side of the rotating frame 45, and the two gears 47 mesh with each other. When using the pay-off frame 1 to pay off yarn and supply yarn to the knitting machine, firstly, the spool 2 equipped with yarn loops is mounted on the rod of the pay-off frame 1, and then the yarn is pressed into the inner wall of the roller 43. The yarn passes through one side of the inner wall of the auxiliary wheel 46, then through several guide wheels of the guide wheel group 3, and finally enters the knitting machine. Then, according to the actual use of the knitting machine, the servo motor 48 on the surface of the mounting frame 41 is started. Because the gear 47 on the rotating frame 45 and the servo motor 48 mesh with each other, the operation of the servo motor 48 will drive the rotating frame 45 to rotate, thereby driving the auxiliary wheel 46 on the rotating frame 45 to move. The auxiliary wheel 46 presses against the surface of the yarn, causing the yarn's sliding trajectory to change. At this time, when using the pay-off frame 1 to supply yarn to the knitting machine, the tightness of the yarn can be adjusted more efficiently, thereby ensuring the stable stretching of the yarn, preventing abnormal situations, and improving the production efficiency and usage effect of the pay-off frame.

[0033] Figure 1 , Figure 2 and Figure 3The adjustment device 4 shown also includes a positioning ring 411, which is mounted on the surface of the rotating frame 45 by means of two connecting plates 410. The positioning ring 411 allows the yarn to pass through the inner wall of the positioning ring 411 when stretched, thereby making the yarn roll stably in the inner wall of the roller 43, ensuring the normal use of the adjustment device 4. A limiting plate 49 is fixedly connected to one side surface of the rotating frame 45. The limiting plate 49 further improves the stability of the yarn. When the yarn is pressed and adjusted by the auxiliary wheel 46 on the rotating frame 45, the yarn can be stuck in the inner wall of the limiting plate 49 when passing through the auxiliary wheel 46, thereby ensuring the stability of the yarn. A stabilizing ring 412 is fixedly connected to the inner wall of the mounting frame 41. The stabilizing ring 412 is sleeved on the arc surface of the two gears 47. The stabilizing ring 412 makes the two gears 47 more stable when meshing, and less prone to displacement or misalignment, thereby ensuring the stable operation of the rotating frame 45.

[0034] Figure 1 , Figure 2 and Figure 4 The cleaning assembly 5 shown includes an assembly plate 51, which is fixedly connected to the surface of the mounting frame 41. A brush roller 53 is provided through the inner wall of the assembly plate 51. One end of the brush roller 53 is connected to a drive motor 52 on the assembly plate 51. When the yarn extends on the roller 43, the drive motor 52 on the assembly plate 51 can be started simultaneously. The operation of the drive motor 52 will drive the brush roller 53 to rotate. While rotating, the brush roller 53 will rotate and rub against the surface of the yarn, thereby removing impurities and foreign objects from the surface of the yarn, thus ensuring the quality of the finished products produced by the knitting machine.

[0035] Figure 1 , Figure 2 and Figure 4 An arc-shaped rod 54 is fixedly connected to one side surface of the assembly plate 51 shown. One end of the arc-shaped rod 54 is fixedly connected to a sleeve 55. Through the arrangement of the arc-shaped rod 54 and the sleeve 55, the spool 2 can pass through the inner wall of the sleeve 55, so that the spool 2 is stably positioned on one side of the brush roller 53, thereby ensuring the stable cleaning of the yarn by the brush roller 53.

[0036] Working principle: When using the pay-off frame 1 to pay off yarn and supply yarn to the knitting machine, the yarn spool 2 with yarn loops is first mounted on the rod of the pay-off frame 1. Then, the yarn is pressed into the inner wall of the roller 43, and then passes through one side of the inner wall of the auxiliary wheel 46, then through several guide wheels of the guide wheel group 3, and finally enters the knitting equipment. Then, according to the actual use of the knitting machine, the servo motor 48 (model MINAS A5) on the surface of the mounting frame 41 is started. Because the gear 47 on the rotating frame 45 and the servo motor 48 mesh with each other, the operation of the servo motor 48 will drive the rotating frame 45 to rotate, thereby driving the auxiliary wheel 46 on the rotating frame 45 to move. The auxiliary wheel 46 presses against the surface of the yarn, changing the sliding trajectory of the yarn. At this time, when using the pay-off frame 1 to supply yarn to the knitting machine, the tension of the yarn can be adjusted more efficiently, thereby ensuring stable yarn stretching, preventing abnormal situations, and improving the production efficiency and performance of the equipment.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
