[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This utility model provides a rope drying device, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a heat preservation mechanism 1 and a heating mechanism 2.

[0024] The insulation mechanism 1 includes an insulation pipe 11 through which a rope passes. An air inlet 111 and an air outlet 112 are respectively provided on the side walls at both ends of the insulation pipe 11.

[0025] The heating mechanism 2 includes a heating box 21, a heating wire 22, and a blower 23. The heating wire 22 and the blower 23 are located inside the heating box 21. The outlet of the heating box 21 is connected to the air inlet 111 of the insulation pipe 11.

[0026] In operation, heating wire 22 serves as the heat source. When the power is switched on, current flows through heating wire 22, causing it to heat up and dissipate a large amount of heat. Blower 23 is installed inside heating chamber 21. During operation, it agitates the air inside heating chamber 21, creating a flowing airflow. Under the action of blower 23, the previously still air continuously passes around heating wire 22 and is fully heated by the heat dissipated by it, causing the air temperature inside heating chamber 21 to rise rapidly, forming hot air. Under the continuous blowing action of blower 23, the hot air flows continuously from the outlet of heating chamber 21 to the air inlet 111 of insulation pipe 11. The rope passes through one end of insulation pipe 11. The hot air from heating chamber 21 enters insulation pipe 11 and surrounds the rope. Because the hot air temperature is higher than the initial temperature of the rope, the hot air transfers heat to the rope, gradually increasing its temperature and achieving the drying effect. The insulation pipe 11 itself has good heat insulation performance, which can reduce heat exchange between hot air and the external environment and reduce heat loss. During the flow of hot air inside the insulation pipe 11, it can maintain a relatively high temperature for a longer period of time, continuously providing heat to the rope and ensuring that the rope has enough time to be fully dried inside the insulation pipe 11 until it exits from the outlet of the insulation pipe 11 to complete the drying process.

[0027] In this invention, the heat insulation effect of the heat insulation pipe 11 reduces heat loss to the surrounding environment and reduces the extra energy consumed to maintain the drying temperature. During the entire drying process, the heating mechanism 2 only needs to generate enough heat to dry the rope, without overheating due to excessive heat loss, thus saving energy consumption such as electricity and reducing production costs. The hot air can be evenly distributed and surround the rope in the heat insulation pipe 11, so that all parts of the rope can fully contact the hot air, ensuring the consistency of the quality of the rope after drying, which is beneficial to the subsequent processing or use of the rope.

[0028] To improve the utilization rate of hot air, please refer to... Figure 1 In a preferred embodiment, the drying device further includes a circulation mechanism 3, which is used to circulate hot air within the insulation pipe 11.

[0029] In operation, when heating mechanism 2 is activated, hot air enters the insulation pipe 11 from heating chamber 21. The hot air is then drawn into circulation mechanism 3 from the outlet of insulation pipe 11 and returns to the inlet of heating chamber 21 along circulation mechanism 3. Upon entering heating chamber 21, the hot air passes around heating wire 22 again and is reheated to a suitable temperature. Then, driven by blower 23, it flows from the outlet of heating chamber 21 back to the inlet of insulation pipe 11, thus forming a cycle. During this cycle, the hot air is continuously reused, and its heat is utilized multiple times. This improves energy efficiency and ensures the temperature stability of the drying environment inside insulation pipe 11.

[0030] To improve the utilization rate of hot air, please refer to... Figure 1 In a preferred embodiment, the circulation mechanism 3 includes a circulation pipe 31 and an exhaust port 32. The inlet of the circulation pipe 31 is connected to the outlet 112 of the heat preservation pipe 11, and the outlet of the circulation pipe 31 is connected to the inlet of the heating box 21. The exhaust port 32 is provided on the circulation pipe 31.

[0031] During operation, the hot air generated by the heating mechanism 2 enters the insulation pipe 11 to dry the rope. The air, which has cooled slightly but still contains a significant amount of heat, flows out from the outlet 112 of the insulation pipe 11 and enters the inlet of the circulation pipe 31. Since the outlet of the circulation pipe 31 is connected to the inlet of the heating chamber 21, the hot air flows towards the heating chamber 21 within the circulation pipe 31. Once inside the heating chamber 21, the hot air is reheated by the heating wire 22, restoring it to a suitable drying temperature. It is then blown into the insulation pipe 11 by the blower 23 within the heating chamber 21 and reused for drying the rope. This creates a hot air circulation path, allowing for the reuse of hot air, improving heat utilization efficiency, and ensuring a relatively stable drying temperature environment within the insulation pipe 11. As the drying process progresses during circulation, the humidity in the hot air gradually increases. If the humidity is too high, it will affect the drying effect. At this point, some of the more humid hot air can be discharged into the external environment through the exhaust port 32. Simultaneously, the exhaust port 32 also helps to balance the air pressure within the circulation system.

[0032] To reduce the humidity of hot air, please refer to... Figure 2 In a preferred embodiment, the circulation pipe 31 is provided with a drying box 4, the exhaust port 32 is provided on the drying box 4, and the drying box 4 is provided with a desiccant.

[0033] During operation, the hot air in the circulation pipe 31 flows from the outlet of the insulation pipe 11 to the inlet of the heating chamber 21, passing through the drying box 4. The drying box 4 is located within the passage of the circulation pipe 31; the hot air must pass through the drying box 4 to continue flowing within the circulation pipe 31, ensuring sufficient contact between the hot air and the desiccant inside the drying box 4. When the moisture-containing hot air passes through the drying box 4, the desiccant utilizes its surface adsorption sites and physicochemical properties to adsorb the moisture in the hot air, thereby reducing the humidity of the hot air.

[0034] For easy replacement of the desiccant, please refer to... Figure 2 In a preferred embodiment, the drying box 4 includes a box body 41 and a cover 42. The box body 41 is disposed inside the circulation pipe 31, and the cover 42 is detachably connected to the circulation pipe 31.

[0035] During use, the desiccant will become saturated after a period of time and lose its drying ability, requiring replacement. The detachable cover 42 makes the desiccant replacement operation simple and convenient. When the desiccant needs to be replaced, simply remove the cover 42 from the circulation tube 31 to directly access the desiccant inside the box 41.

[0036] For easy assembly and disassembly of cover 42, please refer to... Figure 2 In a preferred embodiment, the circulation tube 31 is provided with a receiving groove 43 for accommodating the cover 42, the circulation tube 31 is provided with a plug hole 44, a plug rod 45 is inserted through the plug hole 44, and the cover 42 is provided with a slot 46 for accommodating the plug rod 45.

[0037] When installing the cover 42, first align the cover 42 with the receiving groove 43 on the circulation tube 31. The receiving groove 43 provides an accurate installation position for the cover 42, ensuring that the cover 42 correctly covers the box body 41 of the desiccant box 4 and that the cover 42 fits tightly against the connection of the circulation tube 31 to prevent hot air leakage. Then, pass the insert 45 through the insertion hole 44 on the circulation tube 31 and insert it into the corresponding slot 46 on the cover 42. When it is necessary to remove the cover 42 to replace the desiccant, simply pull the insert 45 out of the slot 46.

[0038] To guide the insertion rod 45, please refer to... Figure 2 In a preferred embodiment, the end of the insert 45 near the cover 42 is spherical.

[0039] In use, when the insert rod 45 is passed through the insertion hole 44 of the circulation tube 31 and inserted into the slot 46 of the cover 42, the spherical end provides excellent guidance. It makes it easier to align with the entrance of the slot 46, reducing the difficulty of precise alignment during insertion and allowing operators to insert the insert rod 45 into the slot 46 more easily and quickly, thereby improving the efficiency of cover 42 installation.

[0040] To improve the stability of the insertion rod 45, please refer to... Figure 2 In a preferred embodiment, a spring 47 is sleeved on the insertion rod 45. One end of the spring 47 is connected to the insertion rod 45, and the other end of the spring 47 is connected to the circulation tube 31. The spring 47 is in a stretched state, and the spring 47 causes the insertion rod 45 to tend to slide towards the cover 42.

[0041] During use, after maintenance operations such as replacing the desiccant are completed, when reinstalling the cover 42 and inserting the insertion rod 45, the tension of the spring 47 helps the insertion rod 45 to quickly and accurately insert into the slot 46. Because the spring 47 continuously attempts to pull the insertion rod 45 towards the cover 42, when the end of the insertion rod 45 approaches the slot 46, the tension of the spring 47 guides the insertion rod 45 smoothly into the slot 46, reducing the difficulty of manual alignment required during insertion. Furthermore, the spring 47 ensures that the insertion rod 45 immediately returns to a state of tight contact with the inner wall of the slot 46 after insertion, allowing the cover 42 to quickly return to a stable, fixed state, ensuring the normal operation of the drying device.

[0042] To ensure the desiccant comes into more complete contact with the hot air, please refer to... Figure 2 In a preferred embodiment, a rotating shaft 5 is rotatably connected to the drying box 4. The rotating shaft 5 extends along the length of the circulation pipe 31. A stirring rod 51 is provided at one end of the rotating shaft 5 inside the drying box 4, and an impeller 52 is provided at the other end of the rotating shaft 5 outside the drying box 4.

[0043] During use, when hot air flows through the circulation pipe 31, it impacts the impeller located outside the drying box 4. Since the impeller is connected to the rotating shaft 5, and the shaft 5 is rotatably connected to the drying box 4, the force exerted by the hot air on the impeller causes it to rotate around the shaft 5. The rotation of the impeller transmits torque through the shaft 5, causing it to rotate synchronously on the drying box 4. A stirring rod 51 is located at one end of the shaft 5 inside the drying box 4. As the shaft 5 rotates, the stirring rod 51 also performs a circular motion. When hot air carrying moisture enters the drying box 4 and comes into contact with the desiccant, the stirring rod 51 agitates the desiccant and hot air. On one hand, the agitation of the stirring rod 51 increases the gaps between the desiccant particles, allowing the hot air to flow more fully within the desiccant and increasing the contact area between the hot air and the desiccant. This helps the desiccant more effectively adsorb moisture from the hot air, improving drying efficiency. On the other hand, the movement of the stirring rod 51 prevents the desiccant from clumping due to prolonged use. If the desiccant clumps together, its surface area will decrease, and its ability to absorb moisture will decline. The stirring rod 51 continuously agitates the desiccant, keeping it in a loose state and ensuring that the desiccant can continue to effectively perform its drying function.

[0044] To improve the cleanliness of hot air, please refer to... Figure 2 In a preferred embodiment, filters 48 are provided on both sides of the drying box 4 inside the circulation pipe 31.

[0045] During use, some fibers may fall off the drying string, or a small amount of debris may remain on the pipe walls within the system. These impurities will flow with the hot air. Filter 48 prevents these impurities from entering the drying box 4, avoiding contact between the impurities and the desiccant, thus preventing contamination of the desiccant and affecting its adsorption performance. The hot air dried in the drying box 4 will pass through filter 48 again on the other side of the drying box 4 as it flows towards the heating chamber 21. This is to prevent desiccant particles from escaping from the drying box 4 due to airflow agitation and being carried by the hot air into the heating chamber 21 or other components. Filter 48 intercepts desiccant particles, ensuring the purity of the hot air within the circulation pipe 31, preventing desiccant loss, and thus ensuring the normal operation of the circulation system and drying device.

[0046] To better understand this utility model, the following is combined with... Figure 1 - Figure 2The working principle of a rope drying device according to this utility model is described in detail below: Heating wire 22 serves as the heating source. When the power is turned on, current flows through heating wire 22, causing it to heat up and dissipate a large amount of heat. A blower 23 is installed inside the heating chamber 21. During operation, the blower agitates the air inside the heating chamber 21, creating a flowing airflow. Under the action of the blower 23, the previously still air continuously passes around the heating wire 22 and is fully heated by the heat dissipated by the heating wire 22, thus rapidly increasing the air temperature inside the heating chamber 21, forming hot air. Under the continuous blowing action of the blower 23, the hot air flows continuously from the outlet of the heating chamber 21 to the inlet of the insulation pipe 11. The rope enters from one end of the insulation pipe 11 and travels inside it. The hot air from the heating chamber 21, after entering the insulation pipe 11, surrounds the rope. Because the hot air temperature is higher than the initial temperature of the rope, the hot air transfers heat to the rope, gradually raising its temperature and thus drying it. The insulation pipe 11 itself has excellent insulation properties, reducing heat exchange between the hot air and the external environment and minimizing heat loss. As the hot air flows within the insulation pipe 11, it maintains a relatively high temperature for a considerable period, continuously providing heat to the rope and ensuring sufficient time for it to be thoroughly dried until it exits the outlet of the insulation pipe 11, completing the drying process.
