The surface of the yarn storage roller 5 is provided with a prismatic socket for the limited insertion of the second prismatic rod 19, so that the sleeve 18 can drive the yarn storage roller 5 to rotate through the second prismatic rod 19 to realize the delivery of the yarn. A pull ring 43 is rotatably installed on the outer side of the sleeve 18, and two symmetrically distributed pulley rods 20 are fixedly installed on the outer side of the pull ring 43. The pulley rod 20 is slidably installed on the inner side of the yarn guide cylinder 2, and an inner gear ring 21 is rotatably installed on the inner side of the yarn guide cylinder 2. Two symmetrically distributed first push blocks 22 are fixedly installed on the top of the inner gear ring 21. The top of a push block 22 contacts the end of the pulley rod 20, and a tension spring 23 is fixedly installed between the bottom of the sleeve 18 and the top of the yarn storage roller 5. When the inner gear ring 21 rotates, the first push block 22 can move away from the pulley rod 20. The rebound force of the tension spring 23 is used to move the sleeve 18 downward and away from the first prismatic rod 17, which can stop the rotation of the yarn storage roller 5 and stop the yarn transportation. A gear motor 44 that cooperates with the inner gear ring 21 is installed on the inner side of the yarn guide drum 2. The infrared alarm 15 is connected to the yarn guide drum 2 and the inner gear ring 21 through the mounting bracket 8.

A positioning cylinder 40 is fixedly installed on the top of the yarn storage roller 5, and the positioning cylinder 40 is slidably installed on the outside of the sleeve 18 to improve the stability of the movement of the sleeve 18.

[0033] Example 3: Please refer to Figure 5-Figure 8, this embodiment is further explained for other embodiments. The line-fixing mechanism shown in the figure includes a positioning frame 24 fixedly mounted on the outside of the yarn guide wheel 4. Two symmetrically distributed rocker rods 25 are rotatably mounted on the outside of the positioning frame 24. A sleeve box 26 is fixedly mounted on the end of the rocker rod 25 away from the yarn guide cylinder 2. A fixing frame 27 is rotatably mounted between the two sleeve boxes 26, and the sleeve box 26 is docked with the fixing frame 27 through a coil spring. A rubber clamping block 28 located below the yarn guide wheel 4 is fixedly mounted on the outside of the fixing frame 27. The rubber clamping block 28 is an arc-shaped structure and has multiple anti-slip grooves. When the rocker 25 swings, it can drive the sleeve box 26 to swing upward with the positioning frame 24 as the fulcrum, and the sleeve box 26 can push one end of the rubber clamping block 28 to contact the yarn on the yarn guide wheel 4 through the fixed frame 27, so as to achieve the pre-positioning of the yarn, and utilize the elasticity of the coil spring to make the rubber clamping block 28 drive the fixed frame 27 to swing with the sleeve box 26 as the fulcrum, so that the arc surface of the rubber clamping block 28 fits the outer side of the yarn guide wheel 4, and the anti-slip groove on the rubber clamping block 28 can fix the yarn on the yarn guide wheel 4, thereby locking the yarn and making it easier for the staff to find the thread end after the yarn breaks. The inner side of the yarn guide cylinder 2 is provided with a cavity for the limited sliding of the rocker rod 25, and the end of the rocker rod 25 away from the sleeve box 26 is provided with a long groove. A pressure rod 29 is slidably installed between the two long grooves, and a spherical block 30 is fixedly installed on the top of the pressure rod 29. The spherical block 30 is slidably installed in the cavity of the yarn guide cylinder 2, and a second push block 31 is fixedly installed on the bottom of the inner gear ring 21. It is located on the outside of the spherical block 30, so that when the inner gear ring 21 rotates, the spherical block 30 can be pushed downward by the second push block 31, and the spherical block 30 can press the rocker rod through the pressure rod 29. The end of 25 swings to realize the movement of the rubber clamp 28. An elastic telescopic rod 32 is fixedly installed between the bottom of the pressure rod 29 and the inner side of the cavity of the yarn guide tube 2, so that the elastic telescopic rod 32 can provide support for the bottom of the pressure rod 29. Two limit rods 41 with a central symmetrical distribution are fixedly installed on the outside of the sleeve 26. Limit disks 42 are fixedly installed at both ends of the fixed frame 27. The outer side of the limit disk 42 is provided with an arc groove for the limit rod 41 to limit the sliding of the limit rod 41, so as to ensure the swing angle of the fixed frame 27 and ensure that the end of the rubber clamp 28 contacts the yarn guide wheel 4 first.

[0034] Working principle: First, the staff passes the yarn in the yarn feeding disc 1 through the yarn presser 3 and the yarn guide wheel 4 and winds it around the yarn storage roller 5, then passes the yarn end through the yarn feeding frame 6, uses the yarn presser 3 to adjust the yarn tension, and uses the straightened yarn to lift the plastic pressure roller 14 so that the plastic pressure roller 14 is against the outside of the yarn. At this time, the staff connects the transmission belt with the pulley 7, so that the transmission belt drives the pulley 7 to rotate, and the pulley 7 drives the rotating rod 16 to rotate, and the first prismatic rod 17 on the rotating rod 16 drives the second prismatic rod 19 to rotate through the sleeve 18, and the second prismatic rod 19 drives the yarn storage roller 5 to rotate, so that the yarn storage roller 5 cooperates with the yarn feeding disc 1 to sew the yarn. The weaving equipment can weave through the yarn. When the yarn breaks, the yarn moves away from the plastic pressure roller 14. The plastic pressure roller 14 drives the U-shaped frame 12 to move downward along the outer side of the first slide bar 11 through the mounting tube 13, so that the plastic pressure roller 14 is close to the infrared alarm 15. The infrared alarm 15 detects that the height of the plastic pressure roller 14 is low and issues an alarm prompt to notify the staff to adjust and repair in time. At the same time, the infrared alarm 15 starts the gear motor 44, so that the gear motor 44 drives the inner gear ring 21 to rotate, and the inner gear ring 21 drives the two first push blocks 22 and the second push blocks 31 to do circular motion. At this time, the two The first push block 22 moves away from the corresponding pulley rod 20, and the sleeve 18 moves downward and away from the first prismatic rod 17 by the rebound force of the tension spring 23. The rotating rod 16 cannot drive the sleeve 18 to rotate through the first prismatic rod 17, and the yarn storage roller 5 stops rotating to prevent the yarn from being pulled. At the same time, the second push block 31 contacts the spherical block 30, so that the second push block 31 pushes the spherical block 30 to move downward, and the spherical block 30 pushes the pressure rod 29 to move and compress the elastic telescopic rod 32. The pressure rod 29 moves along the long groove on the rocker rod 25, so that the rocker rod 25 swings downward with the positioning frame 24 as the fulcrum, and the other end of the rocker rod 25 drives The sleeve box 26 moves upward, so that the sleeve box 26 drives the rubber clamping block 28 on the fixed frame 27 to move synchronously. One end of the rubber clamping block 28 contacts the yarn on the yarn guide wheel 4 to pre-position the yarn, and as the rocker 25 swings, the rubber clamping block 28 drives the fixed frame 27 to swing with the sleeve box 26 as the fulcrum. The arc surface of the rubber clamping block 28 fits the outer side of the yarn guide wheel 4, so that the anti-slip groove yarn on the rubber clamping block 28 is locked on the yarn guide wheel 4. Finally, the staff finds the thread end after the yarn breaks and repairs the broken yarn, thereby achieving the effect of safe weaving, improving the safety of sports protective gear weaving, and ensuring the weaving efficiency of the yarn.
