Description

Technical Field

[0001] The invention relates to the technical field of nylon yarn processing, and in particular to a high-efficiency texturizing processing technology for nylon yarn. Background Art

[0002] Nylon silk is a kind of textile fabric, which has many types such as monofilament, ply yarn, special yarn, etc. Compared with the glossiness of real silk, nylon silk fabric has poorer gloss, as if it is coated with a layer of wax. At the same time, when rubbing back and forth with your hands, you can feel the friction between the fabrics. The stretching process is the process of processing thermoplastic chemical fiber filaments into stretch yarns on a stretch yarn machine.

[0003] The Chinese patent application with the announcement number CN218812357U proposes a nylon yarn elasticizing device, including a high-temperature water tank, a liquid level sensor is arranged on the side of the high-temperature water tank, a water supply pipe is fixedly connected to the high-temperature water tank below the liquid level sensor, a solenoid valve is arranged in the middle of the water supply pipe, an auxiliary box is arranged on the top of the high-temperature water tank, the interior of the auxiliary box is arranged in an inverted bucket-shaped circular cavity, a supplementary rod is slidably connected to the middle of the bottom of the auxiliary box, and a connecting rod is slidably connected to the bottom of the supplementary rod. The present invention is provided with a high-temperature water tank. When the guide roller arranged in the high-temperature water tank drops due to the liquid level, the nylon yarn at the bottom of the guide roller cannot be fully wetted by the hot water in the high-temperature water tank. The supplementary rod moves down along the auxiliary box due to its own weight until the guide hole at the top of the supplementary rod is connected to the water guide pipe. The hot water in the auxiliary box can be sprayed on the nylon yarn through the guide plate for emergency, thereby replenishing the hot water wetting time of the nylon yarn.

[0004] In the actual processing process, the purpose of heat processing the nylon yarn is to avoid the situation that the subsequent untwisting work cannot be carried out properly when the silk path is not heated, which is easy to cause stiff silk, so it needs to be processed. Secondly, heating requires raising the temperature of the filaments to above the glass transition temperature so that the filaments have good thermoplasticity. The above device stores hot water in the auxiliary box to supplement the hot water in the heating box to ensure sufficient moisture inside the heating box, but it is difficult for users to know the amount of water involved in the auxiliary box itself. There may be a lack of supplementary water and affect normal processing. Secondly, since heating requires a certain temperature, the above device cannot guarantee the heat of the reserved water. After adding it, it is still necessary to wait for the temperature to rise to the required value to ensure the heating quality. Correspondingly, there are limitations in its use.

[0034] A cooling mechanism 7 is provided between the upper heat box 1 and the lower heat box 2. The cooling mechanism 7 includes a cooling plate 71, which is fixedly connected between the upper heat box 1 and the lower heat box 2. A fan 72 is provided at the bottom of the cooling plate 71. A bracket 73 is fixedly connected to the outside of the fan 72. A limiting rod 74 is fixedly connected between the upper heat box 1 and the insulation frame 3. The limiting rod 74 passes through the bracket 73. An electric push rod 75 is fixedly connected to one side of the bracket 73.

[0035] A heat conduction mechanism 8 is provided on the lower heat box 2, and the heat conduction mechanism 8 includes a heat conduction pipe 81, which is fixedly connected to the inside of the lower heat box 2, and the heat conduction pipe 81 passes through the insulation frame 3.

The water vapor generated by heating in the lower heat box 2 can be discharged to the outside through the exhaust holes 83.

[0036] In the actual operation process, firstly, the heating device is connected to the power supply. During processing, the nylon yarn passes through the threading hole on the upper heat box 1, the wiring groove 76 on the cooling plate 71 and the threading hole on the lower heat box 2 in turn. The guide wheel assembly 4 conducts the nylon yarn. The upper heat box 1 stores water for heating, and the water replenishing tank 61 stores water to replenish the water lost in the upper heat box 1. The water in the upper heat box 1 needs to immerse the nylon yarn at the bottom. The heating tube 62 heats the water after being energized, thereby heating the immersed nylon yarn. During the heating process, after the heat is transferred to the heat conducting plate 63, the heat conducting plate 63 will also preheat the water in the water replenishing tank 61, so that the water in the water replenishing tank 61 can also maintain a high temperature. When water replenishment is needed, the water with a higher temperature can quickly perform the heating operation, thereby ensuring the heating quality and heating efficiency. After the preliminary heating of the nylon yarn is completed, the nylon yarn can be subjected to a false twisting operation after passing through the false twisting component 5. The structure of the false twisting component 5 is the structure of the existing false twisting device, so it will not be further described here. In the above heating process, the nylon yarn will take away a part of the moisture, resulting in a decrease in the moisture inside the upper heat box 1. The auxiliary frame 67 is connected to the upper heat box 1 through the hole groove, so the water level inside the auxiliary frame 67 is always the same as the water level inside the upper heat box 1. Finally, in order to avoid the situation where the water is heated and boiled, resulting in large fluctuations in the water surface, and then making the floating plate 69 unstable, the heat insulation plate 671 can isolate the heat inside the upper heat box 1, and the moisture can only be transferred through the hole groove with a smaller aperture, which correspondingly reduces the heat transfer between the auxiliary frame 67 and the upper heat box 1. At the same time, in order to further cool down the inside of the auxiliary frame 67, after the heat inside the auxiliary frame 67 is transferred to the heat conducting plate 63, the heat dissipation fins 672 can quickly conduct the heat to the outside world, so as to achieve the purpose of cooling and ensure the stability of the floating plate 69 inside the auxiliary frame 67. The floating plate 69 floats on the water surface inside the auxiliary frame 67. When the water level drops, the floating plate 69 also drops. When the floating plate 69 drops to touch the switch 692, it means that the liquid level inside the upper heat box 1 has dropped to the warning value. At this time, the valve is opened, and the water in the water supply tank 61 passes through the tube body 64 and the nozzle 66 and enters the upper heat box 1 for replenishment. At the same time, the motor 695 works and drives the threaded rod 694 to rotate. The threaded rod 694 drives the moving block 696 to keep moving at a constant speed. The moving block 696 drives the L-shaped plate to move. The time before the L-shaped plate moves to the meshing of the rack 698 and the gear 681 is greater than the time for the water supply tank 61 to replenish the water inside the upper heat box 1 to the set value. Therefore, when the water inside the upper heat box 1 is replenished, the rack 698 is still not meshed with the gear 681. After the replenishment is completed, the floating plate 69 rises again and leaves the switch 692. At this time, the motor 695 drives the threaded rod 694 to rotate in the opposite direction to the above, and the moving block 696 moves to the initial position; On the contrary, if the rack 698 moves with the L-shaped plate to mesh with the gear 681, and the floating plate 69 still does not stop pressing the switch 692, it means that the water in the water replenishment tank 61 may have been used up. At this time, as the moving plate continues to move, the rack 698 drives the gear 681 to rotate, the gear 681 drives the round rod 699 to rotate, and the round rod 699 drives the knocking plate 682 to rotate. After the knocking plate 682 rotates, it repeatedly knocks on the movable block 684. The sound of the knocking can serve as an early warning to the outside world, so that the staff can replenish the water inside the water replenishment tank 61 in time. The device can also adjust the water height of the warning. When adjusting, the threaded adjustment rod 687 is rotated, and the threaded adjustment rod 687 drives the adjustment block 688 to move, and the adjustment block 688 drives the push plate 689 to flip. After the push plate 689 flips, the mounting block 691 is pushed up and down to adjust the height of the mounting block 691, so that the floating plate 69 touches the switch 692 at different heights. The warning height can be adjusted according to the processing requirements, and the use is more flexible. After the nylon yarn is initially processed, it is passed through the wiring groove 76. After the nylon yarn contacts the inner wall of the wiring groove 76, the heat is transferred to the cooling plate 71. The wiring groove 76 is semicircular with an opening at the top, which is more conducive to heat dissipation. Finally, the bottom of the cooling plate 71 is V-shaped. When the fan 72 blows the airflow to the bottom of the cooling plate 71, the V-shaped design is more conducive to the wind force flowing to both sides after contacting the bottom. With the heating of the guide groove 77, the purpose of quickly cooling the cooling plate 71 can be achieved, ensuring that the nylon yarn can be quickly cooled in a short time. In the cooling process, the electric push rod 75 pushes and pulls the bracket 73, and the bracket 73 drives the fan 72 to move, so as to prompt the fan 72 to move to different areas of the bottom of the cooling plate 71 for comprehensive air cooling. After the cooling is completed, the nylon yarn is heated for the second time inside the lower heat box 2. Specifically, the heat inside the upper heat box 1 is transferred to the heat pipe 81, and the heat of the heat pipe 81 inside the lower heat box 2 heats the internal space of the lower heat box 2, thereby achieving the purpose of heating the nylon yarn inside the lower heat box 2. This heating process is non-contact heating, and the moisture contained in the nylon yarn can evaporate during the heating process on the basis of heating, so as to dry it. The drying efficiency is high, and the evaporated moisture is discharged to the outside through the exhaust hole 83 on the exhaust pipe 82, which can avoid the adverse effect of moisture on subsequent processing.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
