9. A warp knitting machine with a precise yarn supply device as claimed in claim 8, characterized in that: Each group of rotating components comprises a mounting gear (313), a mounting motor (312), two transmission gears (314) and a transmission gear ring (315); each transmission gear (314) is fixedly sleeved on an outer surface of one side of the threaded rod (310); one end of the transmission gear ring (315) is rotatably connected to an outer surface of one side of the rotating plate (307); each transmission gear (314) is meshed with the transmission gear ring (315); the mounting motor (312) is fixedly connected to an outer surface of one side of one of the rotating plates (307); the mounting gear (313) is fixedly sleeved on an output end of the mounting motor (312); and the mounting gear (313) and the transmission gear ring (315) are meshed with each other.

10. A method for using a warp knitting machine with a precise yarn supply device, characterized in that: A warp knitting machine with a precise yarn supply device as claimed in any one of claims 1 to 9, comprising the following steps: S1. Yarn transmission: Turn on the connecting motor (406), and the worm (405) can be rotated by the rotation of the connecting motor (406). The worm (405) and the worm wheel (404) are meshed, so that the worm wheel (404) can drive the connecting rod (403) to rotate, and the connecting rod (403) drives the positioning plate (407) and the electric telescopic rod (408) to move, so that the adjustment plate (409) drives the storage rod (410) to rotate to a suitable angle, and then a plurality of yarn rolls are placed on the storage rod (410), and then the storage rod (410) is restored to its original state, and the other feeding mechanism (4) is also operated in the same manner as above; S2, adjusting the yarn tension: connecting the yarn to the storage mechanism (3) through the transmission rod (2); when the yarn tension needs to be adjusted, turning on the electric telescopic rod (408); the electric telescopic rod (408) pushes the adjustment plate (409) and the storage rod (410) to move, thereby adjusting the tension according to actual conditions; S3, supplying yarn: the yarn is connected to the storage reel (309), and then the fixed motor (317) is turned on. The fixed motor (317) drives the rotating plate (307) to rotate, thereby driving the storage reel (309) to rotate and store the yarn. Then the installation motor (312) is turned on. The installation motor (312) rotates to rotate the installation gear (313). The installation gear (313) and the transmission gear ring (315) are meshed, so that the transmission gear ring (315) can be rotated. The transmission gear ring (315) and the transmission gear (314) are meshed, so that the transmission gear (314) drives the threaded rod (310) to rotate. The threaded cylinder (311) cooperates with the limit block (308) to limit the position, so that the storage reel (309) can be moved, so that the yarn can be evenly stored and stored. S4, replenishing yarn: turning on the support motor (302), the rotation of the support motor (302) can cause the fixed gear (303) to rotate, and the engagement of the fixed gear (303) and the fixed gear ring (305) can cause the rotating rod (304) to drive the mounting plate (306) to rotate, so that the yarn can be replenished in time.
