[0033] Refer to Figures 1 - 4 , a double-sided rib jacquard circular knitting machine, including a frame 1 and a yarn rack mechanism 2 arranged on the frame 1;

[0034] The yarn rack mechanism 2 includes a receiving disk 21 and a bracket assembly 22. The receiving disk 21 is located above the center of the frame 1. A plurality of bracket assemblies 22 are provided and are evenly distributed along the circumferential direction of the receiving disk 21. The bracket assembly 22 includes a support plate 221, an adjustment part 222, and a movable plate 223. The adjustment part 222 includes a sleeve 2221 and a rotating shaft 2222. One end of the support plate 221 is fixedly installed on the outer periphery of the receiving disk 21, and the other end is fixedly connected to the sleeve 2221. The rotating shaft 2222 is movably installed inside the sleeve 2221;

[0035] The sleeve 2221 is provided with an opening 22211. One end of the movable plate 223 passes through the opening 22211 and is fixedly connected to the rotating shaft 2222;

[0036] A groove 2231 is provided at one end of the movable plate 223 away from the rotating shaft 2222. A plurality of yarn supporting frames 3 are provided, and each yarn supporting frame 3 is correspondingly arranged in each groove 2231, so that the groove 2231 and the yarn supporting frame 3 form a detachable structure, which can facilitate the installation or disassembly of the yarn supporting frame 3, realize the quick and convenient replacement of the yarn feeder, and both the groove 2231 and the yarn supporting frame 3 are set as arc-shaped structures, which improves the stability during the installation of the yarn supporting frame 3, avoids the shaking of the yarn feeder during the operation of the circular knitting machine, and also improves the production efficiency of the circular knitting machine. When the movable plate 223 rotates along the length direction of the opening 22211 in cooperation with the rotating shaft 2222, the angle of the yarn supporting frame 3 changes, realizing the adjustment of the height of the yarn supporting frame 3, and at the same time, the tension of the yarn can be adjusted, improving the knitting effect of the woven fabric, and greatly improving the practicability of the circular knitting machine.

[0037] Based on the above structure, through the structural setting of the adjusting part 222, when the movable plate 223 rotates along the length direction of the opening 22211 with the cooperation of the rotating shaft 2222, the angle of the yarn support frame 3 changes, and the height of the yarn support frame 3 can be adjusted, so that it is convenient for workers of different heights to repair the yarn feeder on the yarn support frame 3, reducing the safety hazards during maintenance, and the change of the angle and height of the yarn support frame 3 can adjust the tension of the yarn, improve the knitting effect of the weaving, and also improve the practicability of the knitting circular machine. In addition, since a groove 2231 is provided on the end of the movable plate 223 away from the rotating shaft 2222, the yarn support frame 3 can be adjusted. By arranging each yarn support frame 3 in each groove 2231 accordingly, the groove 2231 and the yarn support frame 3 form a detachable structure, which can facilitate the installation or disassembly of the yarn support frame 3 and realize quick and convenient replacement of the yarn feeder. Since the groove 2231 and the yarn support frame 3 are both arranged in an arc structure, when the yarn support frame 3 is located at the groove 2231, the stability of the yarn support frame 3 during installation can be improved, and the yarn feeder can be prevented from shaking when the circular knitting machine is working, so as to ensure the safety of the staff. This design is conducive to optimizing the operating steps of the staff for repairing or replacing the yarn during production, thereby effectively improving the working efficiency of the circular knitting machine and the practicability of the circular knitting machine.

[0038] In one embodiment, referring to Figure 1 and Figure 4 A support frame 23 is provided on the side of the receiving disc 21 close to the frame 1, and a fixing seat 231 is provided at the bottom of the support frame 23. The creel mechanism 2 is connected to the frame 1 through the fixing seat 231. When the inside of the circular knitting machine needs to be inspected, the creel mechanism 2 can be installed and disassembled through the fixing seat 231, and the stability of the creel mechanism 2 during installation is improved through the support frame 23, so as to avoid shaking when the circular knitting machine is working and reduce safety hazards.

[0039] In one embodiment, referring to Figure 1 , Figure 2 and Figure 5, three fixing brackets 11 are evenly arranged around the fuselage of the frame 1. One end of the three fixing brackets 11 away from the frame 1 is in contact with the ground. When the yarn frame mechanism 2 is placed on the frame 1, the pressure received by the frame 1 can be divided and pressed onto the ground through the fixing brackets 11, reducing the probability of the frame 1 being damaged due to stress. Two protective doors 12 are arranged between adjacent fixing brackets 11. The two protective doors 12 are used to seal and block the passage between two adjacent fixing brackets 11, which can isolate the internal drawing and winding mechanism of the circular knitting machine from the outside world and reduce the impact of external dust on the internal drawing and winding mechanism of the circular knitting machine. A connecting component 13 for locking the two protective doors 12 is arranged on two adjacent protective doors 12. The connecting component 13 includes a plugging rod 131, a first lock block 132 and a second lock block 133. The first lock block 132 and the second lock block 133 are respectively arranged on the two protective doors 12. A first plugging hole 1321 is arranged on the first lock block 132, and a second plugging hole 1331 is arranged on the second lock block 133. The plugging rod 131 is plugged in the first plugging hole 1321 and the second plugging hole 1331, so that the protective door 12 can be locked and fixed when it is closed, preventing the protective door 12 from being accidentally opened. A plurality of observation holes 121 are arranged on the protective door 12, and transparent covers 1211 are installed in the observation holes 121. When all the protective doors 12 are closed and locked, the staff can observe the internal working conditions of the circular knitting machine through the transparent covers 1211.
