[0024] A warping yarn guiding device for a circular loom, comprising a base 1, a discharging wheel 3, a motor 5, a lead screw 6, a guiding groove 10, a roller 12, a fixed pulley 16, a spindle 17 and a circular loom 18. A support rod 2 is fixedly connected to the top end of the base 1. A discharging wheel 3 is rotatably connected to one side of the support rod 2. A yarn 4 is arranged outside the discharging wheel 3. A motor 5 is fixedly connected to the inside of the base 1. The output end of the motor 5 is fixedly connected to a lead screw 6. A guiding rod 7 is fixedly connected to the inside of the base 1. A connecting block 8 is spirally connected to the outside of the lead screw 6. One end of the connecting block 8 is detachably connected to a first guiding roller 9. A guiding groove 10 is formed in the first guiding roller 9. A rotating shaft 11 is fixedly connected to the end of the first guiding roller 9 away from the connecting block 8. A roller 12 is arranged at one end of the rotating shaft 11. A housing 13 is detachably connected to one end of the base 1. A sliding groove 14 is formed in the inside of the housing 13. A supporting device 15 is arranged inside the lower part of the base 1. A fixed pulley 16 is arranged at the top end of the base 1. A spindle 17 is arranged above the fixed pulley 16.
[0025] The supporting device 15 includes a second guide roller 1501, a top positioning block 1502, an electric telescopic rod 1503 and a fixed shaft 1504. The fixed shaft 1504 is fixedly connected to the base 1. An electric telescopic rod 1503 is fixedly connected to the outside of the fixed shaft 1504. One end of the electric telescopic rod 1503 is fixedly connected to a top positioning block 1502. A second guide roller 1501 is detachably connected to one side of the top positioning block 1502. There are four top positioning blocks 1502 and four electric telescopic rods 1503 respectively. A guide groove 10 is formed in the second guide roller 1501. The yarn 4 is slidably connected to the first guide roller 9 in the guide groove 10, and the yarn 4 is also slidably connected to the second guide roller 1501 in the guide groove 10. There are twelve spindles 17 which are fixedly arranged in a circumferential array on the circular loom 18.
[0026] Working process: The electricity required for this utility model is provided by an external power supply. When we need to braid the yarn 4, first install the first guide roller 9 on the connecting block 8, then put the second guide roller 1501 on the outside of the top block 1502, and then start the electric telescopic rod 1503 fixed around the fixed shaft 1504 so that the second guide roller 1501 is installed and fixed on the outside of the top block 1502. The supporting device 15 is also arranged inside the base 1, which facilitates the space formed by the base 1 and the housing 13 to protect the first guide roller 9 and the second guide roller 1501. Then, detachably connect the housing 13 to the first guide roller 9 and the second guide roller 1501. The top end of the base 1 is fixedly connected with a support rod 2, and a discharging wheel 3 is rotatably connected to one side of the support rod 2. Then, the staff winds the yarn 4 wound around the outside of the discharging wheel 3 around the guide grooves 10 opened on the first guide roller 9 and the second guide roller 1501. By setting the guide grooves 10, the problem that the yarn 4 is prone to deviation during the feeding process is solved. Then, connect the yarn 4 to the spindle 17 after passing through the fixed pulley 16. After passing through the spindle 17, the yarn 4 enters the circular loom 18 and is ready to be braided. By setting multiple guide rollers and fixed pulleys 16 to cooperate with each other, the impact of vibration on the yarn 4 during the transmission process is reduced. For yarns 4 made of different materials, the required transmission wrap angle is different. By setting the connecting block 8, the lead screw 6 and the motor 5, the first guide roller 9 can move. The movement of the first guide roller 9 changes the relative position, thereby changing the wrap angle between the yarn 4 and the guide roller. For the current yarn 4 in use, after the staff confirms the required wrap angle, start the motor 5. The output end of the motor 5 is fixedly connected with a lead screw 6. The outside of the lead screw 6 is spirally connected with a connecting block 8. The rotation of the lead screw 6 will cause the connecting block 8 to move under the action of the guide rod 7. One end of the connecting block 8 is fixedly connected with a first guide roller 9. The end of the first guide roller 9 away from the connecting block 8 is fixedly connected with a rotating shaft 11. A roller 12 is arranged at one end of the rotating shaft 11. The movement of the connecting block 8 will cause the roller 12 to move in the chute 14 opened on the housing 13, so as to move the first guide roller 9. When the angle between the yarn 4 wound around the first guide roller 9 and the second guide roller 1501 and the second guide roller 1501 reaches the wrap angle set for the work, start the circular loom 18. The yarn 4 will be contracted along the set route, break away from the discharging wheel 3, and enter the circular loom 18 for braiding.
