[0002] Chinese patent document CN214747041U discloses a wear-resistant nylon monofilament drying box. After the motor is started, the hollow shaft can be driven to rotate through the motor gear, synchronous toothed belt and driven gear, which in turn drives the air jet frame and multiple nozzles to rotate, so that hot air is blown evenly onto the nylon monofilament, so that the nylon monofilament is heated evenly, the drying effect is good, and the quality of nylon monofilament is improved.

[0003] In the above scheme, multiple pulleys arranged in an alternating pattern move the nylon monofilament in a wave-like motion within the drying chamber. However, since the heating grid is located above the pulleys and has air outlet nozzles above it, the main heated surface of the nylon monofilament is concentrated at the top during the drying process. The lower part is severely unevenly heated due to the pulleys blocking the heat and the inability of the hot airflow to reach it effectively. This can easily lead to inconsistent moisture evaporation rates at the top and bottom of the monofilament, thereby affecting its mechanical properties and surface quality. Utility Model Content

[0020] Example 1

[0021] like Figure 1-4 As shown, the present invention proposes a wear-resistant nylon monofilament drying box, which includes a box body 1, a conveying rod 2, a ventilation hole 13 and an air conveying pipe; The air supply pipe is installed inside the housing 1 and connected to an external hot air blower to deliver hot air to the inside of the air supply pipe. The air supply pipe has an air inlet and an air outlet at both ends, and the rest of the parts are sealed. The inside of the air supply pipe is provided with a spiral plate 11 for moving the hot air inside the air supply pipe around the nylon monofilament spiral during use. The conveying rod 2 is located in the middle of the air duct and in the middle of the spiral plate 11. The middle of the conveying rod 2 is provided with a through hole along the length direction for conveying nylon monofilaments in use. There are multiple ventilation holes 13, all of which are located on the outer circular surface of the conveying rod 2 and communicate with the through hole in the middle of the conveying rod 2.

[0022] In an optional embodiment, the surface of the spiral plate 11 is provided with a plurality of guide strips 12 facing the ventilation holes 13, which are used to guide the hot air on the surface of the spiral plate 11 during use, so that it moves towards the ventilation holes 13 and then contacts the nylon monofilament in the middle of the conveying rod 2, thereby avoiding the situation where the air volume is small when the hot air contacts the nylon monofilament.

[0023] Multiple ventilation holes 13 are arranged at equal angles around the center of the conveyor rod 2, and the multiple ventilation holes 13 are staggered along the length of the conveyor rod 2, so as to make multi-directional contact with the moving nylon monofilament during the hot air spiral movement, thereby improving the drying uniformity of the nylon monofilament.

[0024] In this embodiment, a through hole for conveying nylon monofilaments is provided in the middle of the conveying rod 2, allowing the nylon monofilaments to pass through the through hole at one end of the housing 1 and be conveyed to the other end of the housing 1. During the conveying process, the air supply pipe is connected to an external hot air blower to deliver hot air into the air supply pipe. At the same time, the delivered air moves along the surface of the spiral plate 11 inside the air supply pipe, allowing the hot air to move from one end to the other inside the air supply pipe. The spiral plate 11 moves spirally around the conveying rod 2, and multiple ventilation holes 13 connected to the through hole in the middle of the conveying rod 2 are provided on the outer circumference of the conveying rod 2. This allows some of the hot air to move towards the middle of the conveying rod 2 and contact the nylon monofilaments for drying. The hot air moves around the nylon monofilaments, ensuring uniform drying of the nylon monofilaments and avoiding uneven heating, thus improving the drying effect.

[0025] Example 2

[0026] like Figure 2-3 As shown, the present invention proposes a wear-resistant nylon monofilament drying box. The difference between this embodiment and the first embodiment is that the air supply pipe includes an air inlet pipe 3, an air outlet pipe 4, and a pipe body. The tube body is located inside the box 1. The tube body is in a sealed state after being connected to the conveying rod 2, and the spiral plate 11 is located inside the tube body. The air inlet pipe 3 is located at one end of the pipe body and is connected to the pipe body, and is also connected to an external hot air blower to deliver hot air into the inside of the pipe body. The exhaust pipe 4 is located at the other end of the pipe body and is connected to the pipe body.

[0027] In this embodiment, hot air is delivered to the inside of the pipe body through the air inlet pipe 3 connected to an external hot air blower, and the hot air moves through the pipe body to the exhaust pipe 4, so that the hot air dries the nylon monofilament inside the pipe body and is discharged through the exhaust pipe 4, so that the nylon monofilament is continuously dried inside the pipe body.

[0028] Example 3

[0029] like Figure 3-4 As shown, the present invention proposes a wear-resistant nylon monofilament drying box. The difference between this embodiment and embodiment two is that the tube body includes a tube body 7 and a flange plate 8. The pipe body 7 is located inside the box 1 and is connected to the air inlet pipe 3 and the air outlet pipe 4; The flange plate 8 is bolted to the end of the pipe body 7 and connected to the conveying rod 2.

[0030] In an optional embodiment, a plurality of support frames 6 are provided on the inner side of the housing 1, and connecting plates 5 are provided on both sides of the tube body 7. The connecting plates 5 are bolted to the support frames 6 to limit the position of the tube body 7 during use and improve the stability of the tube body 7 during use.

[0031] In an optional embodiment, the air inlet pipe 3 is located at the edge of the pipe body 7 and connected to the pipe body 7, with the end of the air inlet pipe 3 facing the inner wall of the pipe body 7. This is used to deliver hot air to the inner wall of the pipe body 7 during use, thereby preventing local overheating at one end of the conveying rod 2 caused by the air inlet pipe 3 delivering hot air to the conveying rod 2.

[0032] In this embodiment, the flange plate 8 is used to seal the end openings of the tube body 7 at both ends, and the flange plate 8 is connected to the conveying rod 2. The conveying rod 2 is placed in the middle of the tube body 7 and connected to the spiral plate 11, so that the nylon monofilament is conveyed inside the tube body 7, and the hot air is in spiral contact with the nylon monofilament inside the tube body 7, thereby improving the drying effect of the nylon monofilament.

[0033] Example 4

[0034] like Figure 3-4 As shown, the present invention proposes a wear-resistant nylon monofilament drying box. Compared with embodiment one, the difference in this embodiment is that an internally threaded pipe 15 is provided in the middle of the flange plate 8 and at one end of the pipe body 7, and an externally threaded groove 14 is provided on the outer side of one end of the conveying rod 2. The end of the conveying rod 2 is inserted into the inner side of the internally threaded pipe 15. The externally threaded groove 14 and the internally threaded pipe 15 are arranged to fix the conveying rod 2 during use, so that the conveying rod 2 and the flange plate 8 can be detachably connected through the externally threaded groove 14 and the internally threaded pipe 15. A retaining ring with the same size as the end face of one end of the conveying rod 2 can be provided on the inner side of the internally threaded pipe 15 to improve the sealing performance when the conveying rod 2 is connected to the internally threaded pipe 15 through the externally threaded groove 14.

[0035] In an optional embodiment, the other end of the conveying rod 2 extends through another flange plate 8 to the outside of the tube body 7. A pressure plate 10 is provided on the outside of the conveying rod 2 and on the side of the other flange plate 8. A gasket 9 connected to the flange plate 8 is provided on the side of the pressure plate 10. During use, the gasket 9 and the pressure plate 10 cooperate to seal the connection between the other end of the conveying rod 2 and the flange plate 8. At the same time, the hot air inside the tube body 7 moves through the ventilation hole 13 into the through hole of the conveying rod 2 and moves to the inside of the other end of the conveying rod 2. When the nylon monofilament is conveyed in the through hole of the conveying rod 2, the hot air at the other end of the conveying rod 2 preheats the nylon monofilament, improving the drying effect of the nylon monofilament.

[0036] In this invention, nylon monofilaments are conveyed from one end of the housing 1 through the through-hole of the conveying rod 2 to the other end of the housing 1. Simultaneously, the air inlet pipe 3 is connected to an external hot air blower to deliver hot air to the inside of the pipe body 7. The hot air moves through the pipe body 7 to the exhaust pipe 4. While the hot air moves inside the pipe body 7, the spiral plate 11 guides the hot air flow inside the pipe body 7. As the hot air moves from the air inlet pipe 3 to the exhaust pipe 4, it spirals around the conveying rod 2. At the same time, through multiple ventilation holes 13 on the surface of the conveying rod 2, some of the hot air moves through the ventilation holes 13 into the through-hole in the middle of the conveying rod 2. This ensures that the hot air comes into full contact with the nylon monofilaments, allowing for thorough drying of the nylon monofilaments, improving the drying uniformity of the nylon monofilaments, avoiding uneven heating, and improving the drying effect.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
