[0001] This utility model relates to the technical field of yarn processing equipment, specifically a yarn stretching device with a double-roller industrial frequency hot roller. Background Technology
[0002] In the yarn production process, hot stretching is a key process to improve the physical properties of yarn (such as strength, elasticity, and dimensional stability). Currently, for yarns processed from synthetic fibers, industrial frequency hot rollers are usually used for stretching during the production process. By heating the yarn with industrial frequency hot rollers, the yarn is ensured to reach the required temperature during the stretching process, which helps to soften the yarn and make it easier to stretch and deform.
[0003] Because the surface temperature of the industrial frequency hot roller is high during operation and there is a lack of corresponding safety protection structures around it, operators are prone to accidentally touching it during equipment debugging or operation, which can cause burns to the workers' skin and affect the safety of personnel operation.

The surface of the locking rod 15 is movably connected to the surface of the locking hole 16.
[0024] In this technical solution, the industrial frequency heated roller body 7 can heat the yarn passing over its surface, causing the yarn to soften under heat and stretch during the traction of the external traction device. Simultaneously, the protective cover 2 and the fixing frame 1 support the industrial frequency heated roller body 7 and protect its surroundings, preventing personnel from contacting the surface of the industrial frequency heated roller body 7 during equipment debugging or operation, thus improving operator safety. Furthermore, the rotating shaft 10, turntable 9, guide groove 17, guide rod 14, clamping rod 15, fixing plate 12, and clamping hole 16 allow for quick removal of the protective cover 2 from the fixing frame 1 during subsequent maintenance, facilitating maintenance of the industrial frequency heated roller body 7 and greatly improving user convenience.
[0025] Example 2:
[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a support plate 11 is movably connected to the middle of the clamping rod 15. The front surface of the support plate 11 is fixedly connected to the lower end of the inner cavity of the protective cover 2. A support spring 13 is fixedly connected between the surface of the support plate 11 and the surface of the clamping rod 15. A guide slide rod 19 is fixedly connected between the surfaces of the two support plates 11. The surface of the guide rod 14 is movably connected to the surface of the guide slide rod 19. Guide slides 18 are fixedly connected to both sides of the inner cavity of the protective cover 2. Guide slide rails 5 are movably connected to the surface of the guide slide rails 18. The back of the guide slide rails 5 is fixedly connected to the surface of the fixed frame 1. Mounting plates 6 are fixedly connected to all four sides of the back of the fixed frame 1. Mounting holes are opened on the surface of the mounting plates 6. Servo motors 8 are fixedly installed at both ends of the back of the fixed frame 1.
