However, while the fan can increase the airflow speed on the surface of the monofilament, it cannot effectively remove moisture mixed within the monofilament. Furthermore, when using a fan, moisture tends to accumulate on the leeward side of the monofilament, resulting in incomplete moisture removal and negatively impacting the production efficiency of the monofilament. Therefore, the existing technology requires further improvement and development. Utility Model Content

Unless otherwise stated, "a plurality of" means two or more.

[0022] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0023] Example Because existing monofilament drying devices blow hot air from only one direction when drying monofilaments, a vortex zone is formed on the leeward side of the monofilament when the hot air blows on it. The gas flow rate in this part is slow, and the water vapor evaporated on the monofilament is not easily blown away, resulting in poor drying effect of the monofilament.

[0024] Therefore, this application discloses a monofilament drying device, which improves drying efficiency and uniformity by blowing hot air evenly on the monofilament from both sides, at multiple points, and along a long path, and by combining hot air recovery and utilization, while saving energy.

[0025] In one specific embodiment, refer to Figure 1 and Figure 2 The monofilament drying device includes a housing 10 and an air conveying structure 20 installed inside the housing 10.

[0026] Reference Figure 1 and Figure 2 The shell 10 forms the outer contour and main load-bearing structure of the entire drying device. It can be made of high-temperature and corrosion-resistant metal materials such as stainless steel to adapt to humid and high-temperature working environments. The shell 10 is provided with an inlet 11 and an outlet 12. The monofilament enters the shell 10 through the inlet 11, and exits through the outlet 12 after drying. A linear drying channel 13 is formed inside the shell 10 between the inlet 11 and the outlet 12, providing space for the monofilament's path.

[0027] In one embodiment of this utility model, reference is made to Figure 3 and Figure 4 The air delivery structure 20 includes a blower 21, a first air outlet assembly 22, a second air outlet assembly 23, and a heating assembly 24.

[0028] Blower 21 can be a centrifugal fan or a high-pressure fan, and its function is to provide a continuous and stable airflow source for the entire device. The air inlet of blower 21 draws in air from the external environment, and the air outlet sends the pressurized air into the subsequent pipeline.

[0029] Specifically, in one embodiment of this utility model, referring to Figure 3 , Figure 5 and Figure 6 The first air outlet assembly 22 is positioned on one side of the drying channel 13, for example, above it; while the second air outlet assembly 23 is positioned on the opposite side of the drying channel 13, for example, below it. This top-to-bottom arrangement allows hot air to blow onto the monofilament simultaneously from both the top and bottom, avoiding the problems of monofilament tumbling or insufficient drying on one side that may be caused by blowing air from one side, and ensuring that the entire circumferential surface of the monofilament is heated evenly.

[0030] The heating component 24 is used to heat the cold air delivered by the blower 21 to the first air outlet component 22 and the second air outlet component 23, so that it reaches the temperature required for the drying process. In one embodiment of this utility model, combined with Figure 6 and Figure 7The blower 21 is connected to the first and second air outlet components 23, which blow the air heated by the heating component 24 from the opposite sides of the drying channel 13 to the moving monofilament through the first and second air outlet components 23, thereby achieving efficient drying operation.

[0031] In one embodiment of this utility model, reference is made to Figure 4 The air delivery structure 20 further includes an air guide duct 25. The inlet 11 of the air guide duct 25 is connected to the outlet 12 of the blower 21 to receive airflow from the blower 21. The air guide duct 25 branches into a first air guide section 251 and a second air guide section 252 along its path, and these two air guide sections are respectively connected to the first air outlet assembly 22 and the second air outlet assembly 23.

[0032] To apply hot air more precisely and evenly to the monofilament, refer to Figure 5 and Figure 6 The first air outlet assembly 22 may include a first air outlet duct 221 and a plurality of first air nozzles 222 arranged along the first air outlet duct 221. Similarly, the second air outlet assembly 23 may include a second air outlet duct 231 and a plurality of second air nozzles 232 arranged along the second air outlet duct 231. (Refer to...) Figure 7 The outlets 12 of these air nozzles all face the drying channel 13. After reaching the end of the air outlet duct, the airflow does not blow out from a large opening, but is blown onto the monofilament in a jet form through these multiple air nozzles distributed along the way. This multi-point blowing method, compared with single-point blowing, can make the hot air cover the monofilaments more evenly throughout the entire drying area.

[0033] Reference Figure 7 In this structure, the heating component 24 may specifically include heat pipes disposed inside the first air outlet duct 221 and the second air outlet duct 231, respectively. As a highly efficient heat transfer element, the heat pipe can rapidly heat the airflow as it passes through. By placing the heat pipes inside the first air outlet duct 221 and the second air outlet duct 231 after the airflow is split, it can be ensured that the air entering the two air outlet components is sufficiently and independently heated.

[0034] Combination Figure 5 and Figure 6 In one embodiment of this utility model, the first air nozzle located above and the second air nozzle located below are both tilted towards the monofilament to blow air, and there is an angle between the airflow and the first partition, thereby avoiding the formation of vortices on the leeward side of the monofilament, so that the water vapor evaporated from the monofilament can be carried away by the hot air.

[0035] Furthermore, in order to ensure that the monofilament receives sufficient drying time and operating distance, in one embodiment, reference is made to... Figure 5 and Figure 6The first air outlet duct 221 and the second air outlet duct 231 are both configured to be arranged along the extension direction of the drying channel 13. The length direction of the air outlet duct is basically parallel to the direction of travel of the monofilament. Through the layout of long pipelines and multiple air nozzles, the interaction path between the hot air and the monofilament is effectively extended, ensuring that the monofilament can be completely dried even at high production line speeds.

[0036] Specifically, in one embodiment of this utility model, referring to Figure 7 The connection surface between the air guide duct 25 and the first air outlet duct 221 is defined as the air inlet plane 253, while the connection surfaces of several first air nozzles 222 and the first air outlet duct 221 together define an air nozzle mounting plane 254. In this embodiment, the air inlet plane 253 and the air nozzle mounting plane 254 are perpendicular. Through this vertical arrangement, the airflow entering the first air outlet duct 221 at high speed from the air guide duct 25 will first impact the inner wall of the air outlet duct, thus generating a certain back pressure and turbulence inside the duct. This causes the airflow to redistribute throughout the duct cavity, making the static pressure in various parts of the duct more uniform. Ultimately, this ensures that the airflow ejected from each air nozzle has a similar velocity and flow rate, improving the uniformity of drying.

[0037] To make the internal structure of the housing 10 more regular and the airflow organization more orderly, this device may also include an internal partition structure 30. Figure 3 and Figure 4 The internal partition structure 30 functionally divides the internal cavity of the housing 10 into an airflow distribution area 34 and a drying operation area 35, and it also physically isolates the first air outlet assembly 22 and the second air outlet assembly 23 in space, so that they are stably located on opposite sides of the drying channel 13.

[0038] In one embodiment of this utility model, reference is made to Figure 4 The internal partition structure 30 includes a first horizontal partition 31 and a second horizontal partition 32 spaced apart. These two partitions are approximately parallel to the path of the monofilament, and the gap between them constitutes the aforementioned drying channel 13. In this structure, the first air outlet assembly 22 is located on one side of the first horizontal partition 31 (as shown above), while the second air outlet assembly 23 is located on the opposite side of the second horizontal partition 32 (as shown below). The structure is clear and easy to install and maintain.

[0039] To further optimize the internal space layout, refer to Figure 4 The internal partition structure 30 may also include a vertical partition 33. The vertical partition 33 is used to separate the airflow distribution area 34 where the blower 21 and the air duct 25 are located from the drying operation area 35 where the first and second air outlet components 23 are located, thereby avoiding airflow interference between different functional areas.

[0040] Finally, in order to improve energy efficiency, refer to Figure 1 The device may also include a hot air recovery structure 40. During the drying process, the interior of the housing 10 will be filled with high-temperature and high-humidity exhaust gas, and direct discharge would result in energy waste. The hot air recovery structure 40 is used to guide this portion of hot air inside the housing 10 to the inlet 11 of the housing 10 to pre-dry the monofilaments that are about to enter the drying channel 13.

[0041] Specifically, in combination Figure 1 and Figure 3 The hot air recovery structure 40 may include a first return air duct 41 and a second return air duct 42. One end of the first return air duct 41 communicates with the upper space inside the housing 10 to collect naturally rising hot air, and the opening at its other end is located directly above the inlet 11 of the housing 10. Similarly, one end of the second return air duct 42 communicates with the lower space inside the housing 10, and the opening at its other end is located directly below the inlet 11 of the housing 10. In this way, the exhaust gas carrying residual heat is captured and guided by the return air ducts, and is preheated and initially dehumidified from both the top and bottom before the monofilament enters the main drying channel 13, effectively reducing the energy consumption of the main drying area and improving the economy of the entire device.

[0042] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
