[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] First Embodiment

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 4 and Figure 5 A nylon filament cooling and shaping device includes a connecting plate 1. Support frames 9 are fixedly connected to both ends of the upper surface of the connecting plate 1. Conveying rollers 12 are rotatably arranged on the front and rear sides between the bottom of the opposite surfaces of the two support frames 9 via a drive mechanism. Moving blocks 14 that move vertically are arranged in the upper part inside the two support frames 9. Cooling rollers 17 are rotatably arranged through the two moving blocks 14. A gantry frame 18 that covers the outside of one end of the surface of the cooling roller 17 is fixedly connected to one end of the upper surface of the connecting plate 1. An infrared thermal imaging sensor 19 with its detection end located above the cooling roller 17 is arranged on the top of the gantry frame 18.

[0024] In this embodiment, after the nylon filament passes between the cooling roller 17 and the two conveying rollers 12, it can exchange heat with the nylon filament through the cooling roller 17, thereby cooling and shaping the nylon filament, improving its toughness, and preventing the macromolecules from breaking down.

[0025] The infrared thermal imaging sensor 19 can accurately control the surface temperature of the cooling roller 17. Precise temperature control improves the crystallinity and orientation consistency of nylon yarn, reduces the defect rate of nylon yarn, and reduces rework and scrap costs.

[0026] A motor 7 is fixedly connected to the rear side of one end of the upper surface of the connecting plate 1, and a reduction gearbox 6 is fixedly connected to the front side of one end of the upper surface of the connecting plate 1. The output shaft of the motor 7 is fixedly connected to the input shaft of the reduction gearbox 6. One end of the conveying roller 12 extends through to the outside of the support frame 9 and is fixedly connected to the first transmission gear 10.

[0027] A second transmission gear 11 is rotatably disposed on the outer side of one end support frame 9, meshing with the two first transmission gears 10. The output shaft of the reduction gearbox 6 is fixedly connected to a drive gear 8 that meshes with one of the first transmission gears 10.

[0028] In this embodiment, after the motor 7 drives the reduction gearbox 6 to work, it can drive the drive gear 8 to rotate. Then, by using the transmission between the two first transmission gears 10 and the second transmission gear 11, the two conveying rollers 12 can be driven to rotate, thereby conveying the nylon yarn.

[0029] One end face of the cooling roller 17 is rotatably connected to the water inlet pipe 20, and the other end face of the cooling roller 17 is rotatably connected to the water outlet pipe 21.

[0030] Several baffles 22 are fixedly connected to the inner wall of the cooling roller 17, and the baffles 22 are evenly spaced along the length of the cooling roller 17.

[0031] In this embodiment, the water inlet pipe 20 facilitates the injection of temperature-carrying liquid into the interior of the cooling roller 17, thereby regulating the surface temperature of the cooling roller 17. The water inlet pipe 20 discharges the used liquid, forming a liquid circulation flow inside the cooling roller 17, thereby continuously maintaining the surface temperature of the cooling roller 17. The baffle 22 turbulents the liquid flowing inside the cooling roller 17, improving the contact effect between the liquid and the inner wall surface of the cooling roller 17.

[0032] Second Embodiment

[0033] Please refer to Figure 2 and Figure 3 Based on the same concept as the first embodiment described above.

[0034] An L-shaped seat 13 is fixedly connected to the other end of the lower surface of the connecting plate 1. A second electric telescopic rod 15 is hinged between the outer side of the moving block 14 at the other end and the other end of the L-shaped seat 13. A guide telescopic rod 16 is vertically fixedly connected between the top of the moving block 14 and the top of the inner wall of the support frame 9.

[0035] In this embodiment, after the second electric telescopic rod 15 extends and retracts, the height of the moving block 14 can be adjusted, which facilitates the adjustment of the distance between the cooling roller 17 and the two conveying rollers 12. This allows for control of the output tension on the nylon filament, preventing filament breakage and improving the stability of the nylon filament cooling and shaping process, thus benefiting the use of the nylon filament cooling and shaping work.

[0036] A receiving seat 5 is fixedly connected to the lower surface of the connecting plate 1. Several first electric telescopic rods 2 are fixedly connected vertically to the top of the inner wall of the receiving seat 5. A lifting plate 23 is fixedly connected to the bottom end of the first electric telescopic rods 2. Vertical plates 3 are fixedly connected to the front and rear sides of the lower surface of the lifting plate 23. A mounting plate 4 is fixedly connected to the bottom of the vertical plate 3. Several mounting holes are opened on the surface of the mounting plate 4.

[0037] In this embodiment, after the first electric telescopic rod 2 extends and retracts, it can drive the lifting plate 23 to move up and down. By connecting the vertical plate 3, it can drive the mounting plate 4 to move up and down, thereby adjusting the height of the adjustment device and facilitating its use in cooling and shaping work with different nylon yarn production lines.

[0038] The working principle of the nylon yarn cooling and shaping device provided by this utility model is as follows:

[0039] After the mounting plate 4 is fixedly installed, the first electric telescopic rod 2 can move up and down, thereby driving the lifting plate 23 to move up and down. By connecting the vertical plate 3, the mounting plate 4 can be moved up and down. The height of the adjusting device can be adjusted. After the nylon yarn passes between the cooling roller 17 and the two conveying rollers 12, it can exchange heat with the nylon yarn through the cooling roller 17, thereby cooling and shaping the nylon yarn. After the second electric telescopic rod 15 moves up and down, the height of the moving block 14 can be adjusted, which makes it easier to adjust the distance between the cooling roller 17 and the two conveying rollers 12. This allows control of the output tension of the nylon yarn, avoids yarn breakage, and improves the stability of the nylon yarn cooling and shaping process.

[0040] Compared with related technologies, the nylon yarn cooling and setting device provided by this utility model has the following beneficial effects:

[0041] After the nylon filament passes between the cooling roller 17 and the two conveying rollers 12, heat exchange occurs between the cooling roller 17 and the nylon filament, thereby cooling and shaping the nylon filament, improving its toughness, preventing macromolecular delamination, and accurately controlling the surface temperature of the cooling roller 17 through the provided infrared thermal imaging sensor 19. This precise temperature control improves the uniformity of the crystallinity and orientation of the nylon filament, reduces the defect rate, and minimizes rework and scrap costs. Furthermore, the height of the moving block 14 can be adjusted by extending and retracting the second electric telescopic rod 15, facilitating the adjustment of the distance between the cooling roller 17 and the two conveying rollers 12. This allows for control of the output tension on the nylon filament, preventing filament breakage, improving the stability of the nylon filament cooling and shaping process, and ultimately benefiting the use of nylon filament cooling and shaping operations.
