[0002] Currently, in the cable processing process, in order to cool the cable after extrusion and sheathing, most companies use a water tank after the extruder head to reduce the cable temperature and solidify the sheath material. As a result, there are many water droplets left on the surface of the cable after it comes out of the water tank. In order to prevent the water from damaging the EDM machine, all the water on the cable must be removed to ensure that the cable is dry before subsequent processing, production and storage can be carried out.

[0026] like Figure 1 As shown, the cable production line of this utility model includes a cable quick-drying device 100. The cable quick-drying device 100 is located after the cooling structure.
[0027] The cable quick-drying device 100 is used to dry the cable 200. The cable quick-drying device 100 includes a drying box 1, an air supply component 2, a drying assembly 3, a self-priming pump 4, and a water return pipe 5.
[0028] The drying chamber 1 is the main structure, and the drying chamber 1 includes a spin-drying zone 11 near the inlet, a drying zone 13 near the outlet, and a blow-drying zone 12 located between the spin-drying zone 11 and the drying zone 13.
[0029] Cable 200 enters the drying chamber 1 from the inlet, passes through the spin-drying zone 11, the blowing zone 12, and the drying zone 13 before exiting from the outlet. Cable 200 undergoes three steps: spin-drying, blowing, and drying. The spin-drying zone 11 quickly removes surface moisture from the cable 200, achieving initial drying. The blowing zone 12 effectively removes residual water droplets from the cable 200's surface using compressed air. The drying zone 13 evaporates fine moisture, enhancing the drying process and ensuring that even deep moisture in the cable 200 is removed.
[0030] The spin-drying area 11 is provided with at least one high-speed guide wheel 111. The cable 200 passes through at least one high-speed guide wheel 111. The high-speed guide wheel 111 drives the cable 200 to vibrate for spin-drying. In this embodiment, the cable 200 passes under the high-speed guide wheel 111. The high-speed guide wheel 111 can also play a guiding role.
[0031] The bottom of the spin-drying area 11 is provided with a spin-drying water tank 112, which is connected to the return water pipe 5. The water that is spun out will fall into the spin-drying water tank 112 and then be discharged from the return water pipe 5.
[0032] A dryer 121 is provided in the drying area 12, and the cable 200 passes through the dryer 121.
[0033] The drying area 12 is provided with at least one partition plate 122, which is spaced apart along the transmission direction of the cable 200. The partition plate 122 divides the drying area 12 into at least two drying chambers 124, and each drying chamber 124 contains a dryer 121. In this embodiment, the cable 200 passes through each partition plate 122 sequentially. Providing multiple drying chambers 124 and a dryer 121 in each chamber improves the drying effect.
[0034] The blowing zone 12 is also separated from the spin-drying zone 11 and the drying zone 13.
[0035] The dryer 121 is made of nylon material and is cylindrical in shape. It has threading holes at both ends along the axial direction for the cable 200 to pass through, and radial air inlets and outlets, both of which are connected to the connecting air pipe 22. In this embodiment, the dryer 121 is rotatable, allowing the air inlets of each drying zone 12 to blow air towards different positions on the cable 200. Thus, the air inlets can deliver drying airflow from various directions to the surface and interior of the cable 200 according to its specific shape and drying requirements, achieving all-around drying and effectively avoiding the problem of insufficient local drying caused by a fixed angle. Of course, the blowing angle needs to be adjusted before operation.
[0036] Each of the dryers 121 is provided with a guide wheel structure to guide the cable 200 to move along a preset path during the production process, thereby providing support, ensuring that the surface of the cable 200 is subjected to uniform force, avoiding problems such as local deformation and scratches caused by uneven force, and ensuring the integrity of the surface of the cable 200.
[0037] Nylon material has good wear resistance and flexibility, preventing cable 200 from being scratched or worn during the production process.
[0038] Each of the drying chambers 124 has a drying water tank 123 at its bottom, and the drying water tank 123 is connected to the return water pipe 5. The blown-off water falls into the drying water tank 123 and is further discharged from the return water pipe 5.
[0039] The air supply component 2 is connected to the dryer 121 to supply air to the dryer 121. The air supply component 2 includes an air supply pump, an air supply valve 21, and a plurality of connecting air pipes 22, each of the connecting air pipes 22 being connected to one of the dryers 121. The connecting air pipe 22 includes at least an air inlet pipe, and in some embodiments may also include an air return pipe.
[0040] The drying zone 13 is equipped with a dryer 131 and a desiccant 132, wherein the dryer 131 is located near the drying zone 12, and the desiccant 132 is located away from the drying zone 12.
[0041] The drying component 3 is connected to the dryer 131 to supply hot air to the dryer 131.
[0042] The bottom of the drying zone 13 is provided with a drying water tank 133, which is connected to the return water pipe 5. During the drying or desiccation process, water falls into the drying water tank 133 and is further discharged from the return water pipe 5.
[0043] The desiccant 132 is located above the cable 200, which mainly refers to the area above the path of the cable 200. The desiccant 132 is provided with multiple air suction holes 134. The desiccant 132 is connected to the drying assembly 3 to draw out moisture.
[0044] The drying assembly 3 includes a water-air separator 31 connected to the desiccant 132, a filter 32 connected to the water-air separator 31, and a vortex air pump 33 connected to the filter 32. The vortex air pump 33 is connected to the dryer 131.
[0045] The self-priming pump 4 connects the water-air separator 31 and the return water pipe 5 to pump the water in the water-air separator 31 into the return water pipe 5.
[0046] In this embodiment, the vortex air pump 33 can simultaneously achieve the effects of blowing air and heating. The vortex air pump 33 generates heat through the following two pathways: (a) heat generation from aerodynamic friction between the high-speed rotor and stator; and (b) the adiabatic temperature rise effect during gas compression. Of course, in some embodiments, other blowers can be used in conjunction with the heating device to achieve similar effects.
[0047] The drying process is as follows: the dried cable 200 passes through the desiccant 132. The vortex air pump 33 creates negative pressure in the desiccant 132, and the air containing moisture enters the water-air separator 31. The water falls into the water-air separator 31, while the dry air passes through the filter 32 and enters the vortex air pump 33, completing the circulation. When the water level in the water-air separator 31 reaches a preset height, the self-priming pump 4 operates to pump water into the return water pipe 5.
[0048] Combining multiple drying methods can reduce energy consumption and improve drying efficiency.
[0049] The working process of the cable quick-drying device 100 of this utility model is as follows:
[0050] The cable 200 first enters the spin-drying zone 11. When the cable 200 passes through it, it comes into contact with the high-speed rotating high-speed guide wheel 111, which quickly shakes out most of the water on the surface of the cable 200, achieving a preliminary spin-drying effect. The shaken-out water flows out with the return water pipe 5.
[0051] The air supply valve 21 responds in conjunction with the air supply, allowing compressed air to flow into the dryer 121 via the connecting air pipe 22. The cable 200 enters the drying area 12 and passes through multiple drying chambers 124 in sequence. Compressed air is blown out by the dryer 121, forming an all-round, multi-angle blowing airflow that precisely acts on the surface of the cable 200, effectively blowing off and dispersing residual water droplets on the cable 200, further reducing the surface humidity of the cable 200. The blown-out moisture flows out through the return water pipe 5.
[0052] Cable 200 enters drying zone 13, where a vortex air pump generates hot air at a stable and suitable temperature. The hot air evenly coats cable 200 through dryer 131, causing the hidden fine moisture within to evaporate, thereby enhancing the drying process and ensuring that deep moisture in cable 200 is also removed.
[0053] Finally, cable 200 enters desiccant 132. The water-air separator 31 is filled with a highly absorbent medium. When the humid airflow carrying cable 200 passes through the water-air separator 31, a large amount of water vapor molecules are captured by the physical adsorption of the medium, significantly reducing the humidity on the surface of cable 200. The water-air separator 31 also stores the recovered moisture. When the water level inside the separator reaches a certain height, the water can be drained through a water pipe into a self-priming pump 4 and then into a return water pipe 5 for discharge. Thus, cable 200 undergoes multiple processes to achieve deep and comprehensive drying.
[0054] During the drying process of cable 200, water droplets blown off or condensed from the surface of cable 200 fall into the spin-drying tank 112, the blow-drying tank 123, and the drying tank 133. These tanks are located below cable 200 and can efficiently collect this moisture, preventing it from flowing around inside the device.
[0055] In addition, the exhausted air enters the gas filter 32 after the water-air separator 31. The gas filter 32 is equipped with multiple layers of filter screens and filter elements, which can effectively intercept pollutants such as dust, impurities, and oil in the air, ensuring that the air entering the vortex air pump 33 is pure and clean.
[0056] The cable quick-drying device 100 and cable production line of this utility model, by setting up a spin-drying zone 11, a blow-drying zone 12 and a drying zone 13, realize multiple diversified processes to make the cable 200 drier, with good drying effect and greatly reduced energy consumption, thereby reducing the production cost of long-term operation.
[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
