Technical Field

[0001] This utility model relates to the field of nylon fiber processing technology, and in particular to a heat setting device for ultra-tough composite nylon filament. Background Technology

[0002] Ultra-tough composite nylon filament is a high-performance nylon fiber prepared through special processes or material composite technology. It possesses excellent mechanical properties such as high strength, high toughness, wear resistance, and impact resistance.

[0003] Because the ultra-tough composite nylon filament generates internal stress during spinning and stretching, resulting in uneven molecular chain segment orientation and low crystallinity, a heat setting device is required to heat the ultra-tough composite nylon filament during the production process.

[0004] The common heat setting method involves installing hot rollers inside the heat setting box. When the ultra-tough composite nylon filament passes through the hot rollers, it comes into contact with the hot rollers, thereby achieving the effect of heating the ultra-tough composite nylon filament.

[0005] When the heat setting device is in use, the hot roller will generate a certain amount of heat. However, not all of this heat will be utilized. The unutilized heat will be directly discharged, resulting in waste. Summary of the Invention

[0006] The purpose of this invention is to provide a heat setting device for ultra-tough composite nylon filaments, which can solve the problems mentioned in the background art.

[0010] Preferably, the adjustment mechanism includes adjusting screws rotatably installed at the four corners inside the heat setting box, with adjusting sliders connected to the outer side of the adjusting screws via screw sleeves, and a lifting plate fixed to the inner side of the adjusting sliders.

[0011] Preferably, there are two sets of lifting plates, and the lifting plates are symmetrically arranged about the horizontal center line of the preheating roller group.

[0012] Preferably, the preheating roller assembly includes a support frame fixed inside the heat setting box, and a limit slider is slidably connected inside the support frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A heat setting device for ultra-tough composite nylon filament includes a heat setting box 1, an adjustment mechanism 2 installed inside the heat setting box 1, a preheating roller group 3 arranged inside the adjustment mechanism 2, a high-temperature heating roller group 5 arranged behind the preheating roller group 3, a first cooling roller group 6 arranged behind the high-temperature heating roller group 5, a second cooling roller group 7 arranged behind the first cooling roller group 6, a cooling roller group 8 arranged behind the second cooling roller group 7, and a heat utilization component 4 arranged below the adjustment mechanism 2.

[0028] The heat utilization component 4 includes a water storage tank 401 fixed to the bottom of the heat setting box 1. The water outlet end of the water storage tank 401 is fixedly connected to an output pipe 402, and the water inlet end of the water storage tank 401 is fixedly connected to a return pipe 404. A water pump 405 is fixed to the side of the water storage tank 401.

[0029] The heat utilization component 4 also includes a central connecting pipe 403 installed between the preheating roller group 3 and the first cooling roller group 6. The central connecting pipe 403 is also located between the first cooling roller group 6 and the second cooling roller group 7. The water pump 405 is fixedly connected to the return water pipe 404. The water storage tank 401 is connected to the return water pipe 404 through the output pipe 402, the preheating roller group 3, the central connecting pipe 403, the first cooling roller group 6, the central connecting pipe 403, the second cooling roller group 7, and the return water pipe 404.

[0030] By adopting the above technical solution, when the water pump 405 is working, the water in the water storage tank 401 can flow back to the water storage tank 401 through the output pipe 402, preheating roller group 3, middle connecting pipe 403, first cooling roller group 6, middle connecting pipe 403, second cooling roller group 7, and return water pipe 404, realizing the multiple utilization of heat and avoiding the direct dissipation of a large amount of unused heat, which would lead to heat waste. The ultra-tough composite nylon filament passes through the front end of the heat setting box 1 and is output from the rear end of the heat setting box 1. Tension rollers can be installed at both ends of the heat setting box 1 as needed to adjust the tension of the ultra-tough composite nylon filament. The ultra-tough composite nylon filament is first preheated by the preheating roller group 3, then heated and shaped by the high-temperature heating roller group 5, and then cooled in a stepped manner by the first cooling roller group 6 and the second cooling roller group 7. After being cooled by the cooling roller group 8, the water enters the preheating roller group 3. While the preheating roller group 3 heats the ultra-tough composite nylon filament, the heat generated by the preheating roller group 3 also heats the water. Then, after passing through the central connecting pipe 403, the hot water enters the first cooling roller group 6. Since the first cooling roller group 6 is not equipped with a heating component, the temperature of the first cooling roller group 6 is lower than that of the preheating roller group 3. At this time, the ultra-tough composite nylon filament, after being heated at high temperature by the high-temperature heating roller group 5, can undergo preliminary cooling when passing through the first cooling roller group 6. Then, the hot water enters the second cooling roller group 7 again through the central connecting pipe 403 to perform secondary cooling on the ultra-tough composite nylon filament, thereby achieving step-by-step cooling and avoiding direct rapid cooling that would affect the stability of the fiber structure.

[0031] Specifically, such as Figure 2 and Figure 4 As shown, the adjustment mechanism 2 includes adjustment screws 202 rotatably installed at the four corners inside the heat setting box 1. The outer side of the adjustment screws 202 is connected to the adjustment sliders 201 through screw sleeves, and the inner side of the adjustment sliders 201 is fixed with lifting plates 203. There are two sets of lifting plates 203, and the lifting plates 203 are symmetrically arranged about the horizontal center line of the preheating roller group 3. The width of the lifting plates 203 is less than the distance between the support frames 301, so that they will not collide with the support frames 301 when descending.

[0032] The preheating roller assembly 3 includes a support frame 301 fixed inside the heat setting box 1, and a limiting slider 302 is slidably connected inside the support frame 301. A central roller 303 passes through the inside of the limiting slider 302, and a heating roller 304 is movably sleeved on the outside of the central roller 303. The heating roller 304 is rotatably connected to the central roller 303. The central roller 303 has a hollow structure. A return spring 305 is provided at the bottom of the limiting slider 302, and the end of the return spring 305 is fixedly connected to the support frame 301. The limiting slider 302 is elastically connected to the support frame 301 through the return spring 305. The central roller 303 is connected to the central connecting pipe 403, the output pipe 402, or the return water pipe 404 according to its actual position or function.

[0033] The structure of the high-temperature heating roller group 5, the first cooling roller group 6, the second cooling roller group 7, and the cooling roller group 8 is roughly the same as that of the preheating roller group 3. The difference is that the two ends of the first cooling roller group 6 are connected to two sets of central connecting pipes 403, and the two ends of the second cooling roller group 7 are connected to the central connecting pipe 403 and the return water pipe 404, respectively. The first cooling roller group 6 and the second cooling roller group 7 do not have heating rollers 304, but directly use heat-conducting rollers and do not have heating function. The heating roller 304 in the cooling roller group 8 is directly the existing cooling roller structure.

[0034] Within the aforementioned roller groups, the high-temperature heating roller group 5 has the highest temperature, followed by the preheating roller group 3, the first cooling roller group 6, and the second cooling roller group 7. The cooling roller group 8 has the lowest temperature. To increase the temperature difference between the first cooling roller group 6 and the second cooling roller group 7, the distance between them can be extended. Since hot water absorbs heat from the ultra-tough composite nylon filament when passing through the first cooling roller group 6, the water in the middle connecting pipe 403 can be cooled by extending the water's transport time within the middle connecting pipe 403, ensuring that the temperature of the second cooling roller group 7 is lower than that of the first cooling roller group 6.

[0035] By adopting the above technical solution, when heat-setting ultra-tough composite nylon filaments, the position of the central roller 303 can be adjusted according to the diameter of the ultra-tough composite nylon filaments. The screw motor fixedly connected to the adjusting screw 202 (not shown in the figure) is started, the adjusting screw 202 rotates, thereby driving the adjusting slider 201 to move. The adjusting screw 202 is a bidirectional screw, thereby driving the lifting plate 203 to move relative to it, thereby pushing the limiting slider 302 on the central roller 303 to slide inside the support frame 301 and squeezing the return spring 305. The ultra-tough composite nylon filaments pass between the heating rollers 304 on the central roller 303, and are heated by the heating rollers 304. Through the set adjustment mechanism 2, the adjusting screw 202 can drive the lifting plate 203 to move, pushing the central roller 303 to move, and adjusting the distance between the two sets of central rollers 303, which is convenient for adapting ultra-tough composite nylon filaments of different diameters.

[0036] Working principle: The position of the central roller 303 is adjusted according to the diameter of the ultra-tough composite nylon filament. The screw motor, which is fixedly connected to the adjusting screw 202 (not shown in the diagram), is started. The adjusting screw 202 rotates, thereby driving the adjusting slider 201 to move. The adjusting screw 202 is a bidirectional screw, which in turn drives the lifting plate 203 to move relative to it. This pushes the limiting slider 302 on the central roller 303 to slide inside the support frame 301 and squeezes the return spring 305. The ultra-tough composite nylon filament is first preheated by the preheating roller group 3, and then heated and shaped by the high-temperature heating roller group 5. When the water pump 405 is working, the water in the water tank 401 flows back to the water tank 401 through the output pipe 402, the preheating roller group 3, the middle connecting pipe 403, the first cooling roller group 6, the middle connecting pipe 403, the second cooling roller group 7, and the return water pipe 404. Then the ultra-tough composite nylon filament is... The filaments pass through the first cooling roller group 6 and the second cooling roller group 7, and finally through the cooling roller group 8 for further cooling. After entering the preheating roller group 3, the water is heated by the heat generated by the preheating roller group 3 while simultaneously heating the ultra-tough composite nylon filaments. The hot water then enters the first cooling roller group 6 after passing through the central connecting pipe 403. Since the first cooling roller group 6 does not have a heating component, the temperature of the first cooling roller group 6 is lower than that of the preheating roller group 3. The ultra-tough composite nylon filaments, having already been heated by the high-temperature heating roller group 5, undergo preliminary cooling when passing through the first cooling roller group 6. The hot water then enters the second cooling roller group 7 again through the central connecting pipe 403 for secondary cooling of the ultra-tough composite nylon filaments, thus achieving a step-by-step cooling process and avoiding direct and rapid cooling that could affect the stability of the fiber structure.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
