Technical Field

[0001] The utility model relates to the technical field of nylon thread production, in particular to a shaping device for nylon thread production. Background Art

[0002] Nylon itself has high strength, low density, good resilience, good fatigue resistance, good thermal stability and wear resistance. It is an important engineering plastic. In the production process of nylon wire, a shaping device is needed to perform shaping and other processes. When the nylon wire comes out of the hot air box, the surface temperature of the nylon wire is high, which can easily lead to the accelerated volatilization of the oil on the surface of the nylon wire and reduce the adhesion of the oil on the surface of the nylon wire, seriously affecting the oiling effect of the nylon wire surface.

[0003] In the prior art, a rapid air cooling device for nylon thread with publication number CN 221161215 U records that the nylon thread body moves in a spiral manner in the air cooling box, which increases the contact time between the nylon thread body and the gas in the air cooling box and improves the cooling effect of the device on the nylon thread body.

[0004] However, the above scheme adopts a horizontal blowing method to cool the nylon thread, which has a low cooling efficiency and a poor cooling effect on the nylon thread. Therefore, we propose a shaping device for nylon thread production. Utility Model Content

[0005] In view of the shortcomings of the existing device that uses horizontal blowing to cool down the nylon thread, the cooling efficiency is low and the cooling effect on the nylon thread is not good, the utility model provides a shaping device for nylon thread production, which has the advantages of improving the cooling efficiency and improving the production quality of nylon thread, and solves the problems raised in the above-mentioned background technology.

[0006] The technical solution of the utility model is achieved as follows: a shaping device for nylon thread production, including an air cooling box, air supply mechanisms are symmetrically connected on both sides of the air cooling box, two rows of threading holes are opened on a side wall of the air cooling box perpendicular to the air supply mechanism, and multiple groups of wire mechanisms are arranged from top to bottom in the air cooling box, each group of wire mechanisms includes a connecting shaft symmetrically arranged in the air cooling box, a plurality of guide rollers are connected to the connecting shaft, the ends of the connecting shaft are slidably connected in a strip frame, the strip frame is fastened to the inner wall of the air cooling box, and air guide plates are connected to the inner top and bottom surfaces of the air cooling box, and the air guide plates are arc-shaped structures with openings arranged toward the connecting shaft.

[0008] Optionally, one side of the air guide plate is fastened to the inside of the air cooling box through a connecting seat.

[0009] Optionally, the air supply mechanism includes a through groove formed in the side wall of the air-cooling box, a ventilation hole is provided at the top of the air-cooling box, an installation box body is connected to the outside of the through groove, and a first fan is connected to the outer wall of the installation box body.

[0010] Optionally, a fixing frame is fixedly connected inside the installation box body, a refrigeration device is fastened on the fixing frame, and a second fan is connected to one side of the installation box body close to the through groove through an installation frame.

[0011] Optionally, filters are installed at the bottom of the through groove and the ventilation hole, a connecting skirt is arranged at the outer edge of the installation box body, and the connecting skirt is fastened to the outer wall of the air-cooling box.

[0012] Optionally, bases are connected to the four corners of the bottom of the air-cooling box.

[0013] Compared with the prior art, in the present utility model, air guiding plates are arranged on the inner top surface and the bottom surface of the air-cooling box, and the air guiding plates are arc-shaped structures with openings facing the connecting shafts.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to Figures 1 to 5 , the present utility model provides a technical solution: a shaping device for nylon silk thread production, including an air-cooling box 1. Through grooves 8 are symmetrically connected to both sides of the air-cooling box 1. Ventilation holes 5 are arranged at the top of the air-cooling box 1. An installation box body 3 is connected to the outside of the through groove 8. A connecting skirt 2 is arranged on the outer edge of the installation box body 3. The connecting skirt 2 is fastened to the outer wall of the air-cooling box 1. In actual use, the connecting skirt 2 and the air-cooling box 1 are fastened by bolts, which facilitates the staff to install and disassemble the installation box body 3 and improves the practicability of the device.

[0023] As Figure 1 , 2 , shown in Figures 3, a first fan 4 is connected to the outer wall of the installation box body 3. A fixing frame 11 is fixedly connected inside the installation box body 3. A refrigeration device 9 is fastened on the fixing frame 11. And a second fan 10 is connected to one side of the installation box body 3 close to the through groove 8 through a mounting frame 12. In order to prevent foreign impurities from entering the air-cooling box 1, filter screens 7 are installed in both the through groove 8 and the bottom of the ventilation hole 5, thereby playing a role in protecting the nylon silk thread 22 passing through the inside of the air-cooling box 1. And the cooperation of the second fan 10 and the refrigeration device 9 can blow cold air into the air-cooling box 1, which can further improve the shaping efficiency.

[0024] As Figure 4 , 5As shown in the figure, during actual use, two rows of wire passing holes 6 are provided on one side wall of the air-cooled box 1 perpendicular to the air supply mechanism. Inside the air-cooled box 1, multiple groups of wire guiding mechanisms are arranged from top to bottom. Each group of wire guiding mechanisms includes connecting shafts 18 symmetrically arranged inside the air-cooled box 1. A plurality of guiding rollers 17 are connected to the connecting shafts 18. The ends of the connecting shafts 18 are slidably connected inside a strip-shaped frame 13. The strip-shaped frame 13 is fastened to the inner wall of the air-cooled box 1. A guiding rod 14 is fastened inside the strip-shaped frame 13. One end of the connecting shaft 18 is connected to a sliding seat 16. The guiding rod 14 passes through the sliding seat 16. Reset springs 15 are connected to both sides of the sliding seat 16. The reset springs 15 are coaxially arranged with the connecting shafts 18. The nylon thread 22 enters the inside of the air-cooled box 1 through the wire passing hole 6 on one side, winds around the guiding rollers 17 in sequence, and finally exits the air-cooled box 1 through the wire passing hole 6 on the other side. During the movement of the nylon thread 22, a pulling force is generated on the guiding rollers 17. The reset springs 15 arranged inside the strip-shaped frame 13 can buffer the generated pulling force, avoiding damage to the nylon thread 22 caused by excessive tension.

[0025] In summary, for the shaping device for producing nylon threads, during use, in order to improve the air circulation inside the air-cooled box 1, as Figure 5 shown, air guiding plates 19 are connected to both the inner top surface and the bottom surface of the air-cooled box 1. The air guiding plates 19 are arc-shaped structures with openings facing the connecting shafts 18. One side of the air guiding plates 19 is fastened to the inside of the air-cooled box 1 through connecting seats 21. The cold air blown into the air-cooled box 1 by the second fan 10 can move downward under the guiding action of the air guiding plates 19 ( Figure 5 as indicated by the arrow in the figure), ensuring sufficient contact between the nylon thread 22 and the cold air, effectively improving the shaping efficiency. And in order to improve the overall stability of the device, bases 20 are connected to the four corners at the bottom of the air-cooled box 1.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
