Description

Technical Field

[0001] The invention relates to the field of cables, and in particular to a cable drawing device with a drying device. Background Art

[0002] Cable drawing is widely used in the production of cables and wires. Through wire drawing, cables and wires of various specifications and models can be manufactured for power transmission, signal transmission and other fields. However, after the cable is drawn, it needs to be cooled, and the existing wire drawing equipment usually uses water cooling to cool down, and directly rewinds. The water droplets attached to the surface of the copper wire will affect the storage of the copper wire.

[0003] The currently disclosed Chinese patent authorization announcement number is CN110918667B. A copper core wire drawing cooling mechanism and wire drawing equipment, including a mounting plate for mounting a guide wheel group; a water storage container arranged below the mounting plate for storing cooling water; the guide wheel group, including a first guide wheel mounted on the mounting plate; a first direction-changing wheel located directly above the first guide wheel; a first cooling wheel located at one end in the water storage container and directly below the first guide wheel; a second cooling wheel located at the other end in the water storage container and at the same horizontal position as the first cooling wheel; a second direction-changing wheel located directly above the second cooling wheel and at the same horizontal position as the first direction-changing wheel; the copper core wire after diameter change passes through the first guide wheel, the first direction-changing wheel, the second cooling wheel, the first cooling wheel and the second direction-changing wheel in sequence; a guide sleeve is also arranged on the mounting plate, the guide sleeve is arranged between the first direction-changing wheel and the second cooling wheel, a guide hole is arranged in the guide sleeve, and the copper core wire moving from the first direction-changing wheel to the second cooling wheel is in line with the center line of the guide hole.

[0004] According to the above patent, the guide sleeve of the above patent is arranged between the first turning wheel and the second cooling wheel, which effectively avoids the contact between the copper core wire and the mounting plate caused by vibration, thereby effectively avoiding scratch defects on the copper core wire during the cooling process. Due to the contact between the guide sleeve and the copper core wire, the moisture on the copper core wire can be taken away. However, a certain amount of moisture will still remain on the surface of the copper core wire, and the copper core wire cannot be fully dried. Therefore, there is a need for a cable drawing device that can fully dry the copper core wire. Summary of the invention

[0005] In view of the problems existing in the prior art, a cable wire drawing device with a drying device is provided. The present invention realizes efficient drying of the copper wire through the synergistic effect of a water-blocking component and an air-drying component, ensuring effective separation of moisture without wearing the copper wire. A high-speed airflow blows toward the surface of the copper wire from an angle opposite to the moving direction of the copper wire, completely drying the moisture on the surface of the copper wire, effectively preventing the moisture from re-attaching.

[0006] In order to solve the problems of the prior art, the present invention provides a cable drawing equipment with a drying device, comprising a mounting plate, a lower guide wheel rotatably arranged on the mounting plate, and an upper guide wheel rotatably arranged on the mounting plate and located above the lower guide wheel, and also comprising a dehumidification mechanism arranged between the upper guide wheel and the lower guide wheel for removing moisture on the surface of the copper wire when the copper wire moves. A frame for installing the dehumidification mechanism is fixedly provided on the mounting plate, and the dehumidification mechanism comprises a water-blocking component for first separating water droplets on the surface of the copper wire and an air-drying component for further drying residual moisture on the surface of the copper wire. The water-blocking component is located below the air-drying component. When the copper wire is wound up, the copper wire passes through the water-blocking component and the air-drying component in sequence, so that the copper wire is fully dried. The airflow direction of the gas blown out by the air-drying component is opposite to the moving direction of the copper wire. When the copper wire is wound up, the moisture on the copper wire is pushed downward by the airflow, thereby preventing the moisture from re-attaching to the air-dried copper wire.

[0007] Preferably, the water-blocking assembly includes a water-blocking ring for the copper wire to pass through and fit with it, and a sleeve sleeved on the water-blocking ring, the sleeve is fixedly connected to the frame, the upper end of the water-blocking ring is fixedly connected to the sleeve, and the sleeve is fixedly provided with a drainage groove located below the water-blocking ring and used to recover the blown-away water droplets, and the drainage groove has a drain outlet.

[0008] Preferably, the water blocking ring is made of sponge material, and the lower end of the water blocking ring has a guide surface for the copper wire to pass through. A pressure structure is provided on the sleeve. When the pressure structure acts on the water blocking ring, the water blocking ring is in a compressed and deformed state, so that the copper wire is tightly wrapped in the water blocking ring.

[0009] Preferably, the pressure structure comprises a sliding sleeve slidably mounted on the lower half of the sleeve and a pressure driver for driving the sliding sleeve to move, pressure-receiving parts protruding outward are fixedly provided on all four sides of the water-blocking ring, a pressure-receiving part corresponding to each pressure-receiving part on the sliding sleeve extends inwardly and contacts the outer wall of the water-blocking ring, and a sliding groove for the pressure-receiving part to move is provided on the lower half of the sleeve along its axial direction, and when the sliding sleeve moves upward, the pressure-receiving part passes through the pressure-receiving part so that the water-blocking ring is in a state of being squeezed from the outside to the inside.

[0010] Preferably, the pressure-applying portion is a block-shaped structure, the pressure-receiving portion is a spherical structure, and the upper end of the pressure-applying portion has an inclined surface that can smoothly pass through the pressure-receiving portion.

[0011] Preferably, an extrusion tube capable of extruding the water-blocking ring downward is coaxially provided on the upper half of the sleeve, and the sleeve is provided with an extrusion driver for driving the extrusion tube to move. The extrusion tube is located above the water-blocking ring. When the extrusion tube moves downward, the water-blocking ring is in a stretched state, so that the water in the water-blocking ring is squeezed into the drainage groove.

[0012] Preferably, the inner diameters of the extruded tube and the drainage groove are both larger than the diameter of the copper wire.

[0013] Preferably, the air-drying component includes an air outlet pipe arranged at the upper end of the sleeve for the copper wire to pass through, and a downward-inclined air inlet hole is opened on the pipe wall of the air outlet pipe facing the direction of the copper wire, and a plurality of the air inlet holes are opened around the air outlet pipe.

[0014] Preferably, a heating wire is fixedly provided inside the air outlet duct in the form of a spiral winding along its axial direction, a speed sensor is provided on the upper guide wheel, and a controller for controlling the power of the heating wire is provided on the air outlet duct. The speed sensor is electrically connected to the controller. When the speed of the copper wire increases, the speed of the upper guide wheel increases accordingly, so that the heat output of the heating wire is in a state of synchronous increase.

[0015] Preferably, a rubber sleeve is fixedly provided at the upper end of the air outlet pipe for the copper wire to pass through and is tightly attached to the copper wire, a movable gap is left between the lower end of the air outlet pipe and the upper end of the sleeve, and an elastic connector is fixedly connected between the air outlet pipe and the sleeve.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention fully dries the copper wire through the synergistic effect of the water blocking component and the air drying component. That is, during the movement of the copper wire, the copper wire passes through the water blocking component and the air drying component in sequence.

[0017] First, most of the moisture on the surface of the copper wire is separated and collected by friction through the water-blocking component, reducing the burden of subsequent air drying.

[0018] The high-speed airflow of the air drying component is then blown onto the surface of the copper wire to completely dry out the remaining moisture. The direction of the airflow is opposite to the direction of movement of the copper wire, which effectively prevents the moisture from reattaching. Ultimately, the uniformity and thoroughness of the drying is ensured, and the quality of the copper wire is guaranteed.

[0019] 2. The water-blocking ring of the sponge material of the present invention can provide sufficient friction when in contact with the copper wire due to its good water absorption and elasticity, thereby ensuring effective separation of water without wearing the copper wire.

[0020] When the copper wire passes through the water-blocking ring, the pressure structure acts on the water-blocking ring, causing the water-blocking ring to deform under pressure and tightly wrap the copper wire. The water-blocking ring separates and absorbs most of the moisture on the surface of the copper wire through close contact and friction with the surface of the copper wire.

[0021] 3. The present invention uses the synergistic effect of airflow and heating wire to rapidly evaporate the moisture on the surface of the copper wire, thereby improving the drying efficiency.

[0022] The direction of the airflow is opposite to the moving direction of the copper wire, which effectively prevents the moisture from reattaching to the dried part of the copper wire and ensures the uniformity and thoroughness of the drying.

[0023] During the air drying process of the copper wire, the power of the heating wire is dynamically adjusted according to the moving speed of the copper wire to ensure the best drying effect at different speeds.

[0024] 4. The present invention fits the copper wire to the air outlet pipe through the rubber sleeve, and when the copper wire deviates, it can drive the air outlet pipe to move together.

[0025] With the elastic connector connecting the air outlet pipe and the sleeve, the air outlet pipe can adapt to the different movement trajectories of the copper wire, ensuring that the direction of the airflow is always opposite to the moving direction of the copper wire, effectively preventing moisture from reattaching to the dried part of the copper wire.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figure 1-Figure 7 As shown, a cable drawing device with a drying device comprises a mounting plate 1, a lower guide wheel 3 rotatably arranged on the mounting plate 1, and an upper guide wheel 4 rotatably arranged on the mounting plate 1 and located above the lower guide wheel 3, and also comprises a dehumidification mechanism 5 arranged between the upper guide wheel 4 and the lower guide wheel 3 for removing surface moisture of the copper wire 2 when the copper wire 2 moves. A frame 11 for mounting the dehumidification mechanism 5 is fixedly provided on the mounting plate 1. The dehumidification mechanism 5 comprises a water-blocking component 6 for first separating water droplets on the surface of the copper wire 2 and an air-drying component 7 for further drying residual moisture on the surface of the copper wire 2. The water-blocking component 6 is located below the air-drying component 7. When the copper wire 2 is wound up, the copper wire 2 passes through the water-blocking component 6 and the air-drying component 7 in sequence, so that the copper wire 2 is fully dried. The airflow direction of the gas blown out by the air-drying component 7 is opposite to the moving direction of the copper wire 2. When the copper wire 2 is wound up, the moisture on the copper wire 2 is pushed downward by the airflow, thereby preventing the moisture from re-attaching to the air-dried copper wire 2.

[0039] The copper wire 2 between the upper guide wheel 4 and the lower guide wheel 3 is in a vertical state. When the copper wire 2 is wound up, the copper wire 2 between the upper guide wheel 4 and the lower guide wheel 3 is in a moving state from bottom to top.

[0040] When the copper wire 2 is cooled after drawing, it enters the cable drawing equipment with a drying device. During this process, the copper wire 2 is first passed around the lower guide wheel 3, and then passed through the dehumidification mechanism 5 and wound out from above the upper guide wheel 4. The copper wire 2 is wound by the winding device.

[0041] When the copper wire 2 is being rolled up, the first thing it encounters is the water-blocking component 6. The water-blocking component 6 separates most of the moisture on the surface of the copper wire 2. It effectively absorbs most of the water droplets on the surface of the copper wire 2. When the copper wire 2 passes through the water-blocking component 6, the water-blocking component 6 will contact the surface of the copper wire 2, and separate and collect the water droplets on the surface of the copper wire 2 by friction. This not only reduces the burden of subsequent air drying, but also lays a good foundation for the thorough drying of the copper wire 2.

[0042] After the copper wire 2 passes through the water blocking component 6, the copper wire 2 section between the upper guide wheel 4 and the lower guide wheel 3 continues to move from bottom to top, and then the copper wire 2 enters the air drying component 7. The air drying component 7 uses high-speed airflow to completely dry the remaining moisture on the surface of the copper wire 2. When the copper wire 2 enters the air drying component 7, the high-speed airflow blows toward the surface of the copper wire 2 from above, and quickly blows away the remaining moisture.

[0043] The direction of the airflow is opposite to the moving direction of the copper wire 2. When the copper wire 2 moves in the air-drying assembly 7, the airflow not only dries the copper wire 2, but also prevents the moisture from reattaching. Since the direction of the airflow is opposite to the moving direction of the copper wire 2, the airflow pushes the moisture on the surface of the copper wire 2 downward and away from the surface of the copper wire 2. This effectively avoids the problem of the copper wire 2 being reattached with moisture due to the rebound of the airflow during the air-drying process, and ensures the uniformity and thoroughness of the drying.

[0044] After the copper wire 2 passes through the air drying assembly 7, the moisture on the surface has been completely removed and reaches the drying standard. In order to ensure the effect of the drying process, a humidity sensor is used to detect the humidity on the surface of the copper wire 2 to ensure that it meets the predetermined standard. Finally, the electrical performance test is performed on the dried copper wire 2 to ensure that its insulation performance and mechanical properties meet the requirements.

[0045] See also Figure 2-Figure 8 As shown, the water-blocking assembly 6 includes a water-blocking ring 61 for the copper wire 2 to pass through and fit therewith, and a sleeve 62 sleeved on the water-blocking ring 61, the sleeve 62 is fixedly connected to the frame 11, the upper end of the water-blocking ring 61 is fixedly connected to the sleeve 62, and a drainage groove 63 is fixedly provided in the sleeve 62, which is located below the water-blocking ring 61 and is used to recover the blown-away water droplets, and the drainage groove 63 has a drain port 631.

[0046] When the copper wire 2 enters the water blocking assembly 6, it first passes through a water blocking ring 61 through which the copper wire 2 passes and is attached. When the copper wire 2 passes through the water blocking ring 61, the water blocking ring 61 separates and scrapes off most of the water on the surface of the copper wire 2 through friction with the surface of the copper wire 2. The scraped water flows into the drainage groove 63 to collect the water separated from the water blocking ring 61.

[0047] When the water flows into the drainage groove 63 from the bottom of the water blocking ring 61, the water in the drainage groove 63 is discharged through the drain port 631. The drain port 631 is connected to the external drainage system, and the water is directly discharged into the drainage system, thereby achieving effective recovery and discharge of the water. This not only ensures that most of the water on the surface of the copper wire 2 is effectively removed, but also avoids the continuous dripping of the water scraped off the surface of the copper wire 2, thereby improving the drying effect.

[0048] See also Figure 2-Figure 8 As shown, the water blocking ring 61 is specifically made of sponge material, and the lower end of the water blocking ring 61 has a guiding surface for the copper wire 2 to pass through. A pressure structure 611 is provided on the sleeve 62. When the pressure structure 611 acts on the water blocking ring 61, the water blocking ring 61 is in a compressed and deformed state, so that the copper wire 2 is tightly wrapped in the water blocking ring 61.

[0049] When the copper wire 2 enters the water blocking ring 61, the sponge material water blocking ring 61 can provide sufficient friction when in contact with the copper wire 2 due to its good water absorption and elasticity, ensuring effective separation of water without wearing the copper wire 2. When the copper wire 2 passes through the water blocking ring 61, the water blocking ring 61 separates most of the water on the surface of the copper wire 2 through close contact and friction with the surface of the copper wire 2, so that the water on the surface of the copper wire 2 is absorbed by the water blocking ring 61.

[0050] In order to ensure that the water blocking ring 61 is in full contact with the copper wire 2, the water blocking ring 61 is compressed and deformed by the pressure structure 611, so as to tightly wrap the copper wire 2. The compressed and deformed state of the water blocking ring 61 forms a closer contact between the water blocking ring 61 and the copper wire 2, further enhancing the friction force and improving the water separation effect. At the same time, since the sponge material of the water blocking ring 61 has good resilience, it can maintain its water absorption performance even under pressure, ensuring that the water is effectively absorbed and separated.

[0051] See also Figure 4-Figure 9 As shown, the pressure structure 611 comprises a sleeve 6111 slidably mounted on the lower half of the sleeve 62 and a pressure driver 6112 for driving the sleeve 6111 to move. Pressure receiving portions 612 protruding outward are fixedly provided around the water blocking ring 61. A pressure-applying portion 613 inwardly extends from the sleeve 6111 corresponding to each pressure-applying portion 612 and contacts the outer wall of the water blocking ring 61. A sliding groove for the pressure-applying portion 613 to move is provided in the lower half of the sleeve 62 along its axial direction. When the sleeve 6111 moves upward, the pressure-applying portion 613 passes through the pressure-applying portion 612, so that the water blocking ring 61 is in a state of being squeezed from the outside to the inside.

[0052] The pressure driver 6112 is specifically an electromagnetic drive structure, which uses the magnetic field generated by the electromagnet to interact with the magnetic material in the sleeve 6111 to generate magnetic force. When the electromagnet is energized, the magnetic field generated causes the sleeve 6111 to be acted upon by the magnetic force, thereby pushing the sleeve 6111 to move along a predetermined path. By controlling the current intensity and direction of the electromagnet, the moving position of the sleeve 6111 can be accurately adjusted to achieve pressure on the water blocking ring 61.

[0053] The sleeve 62 has a guide rod 621 extending outward through the sliding sleeve 6111, the axial direction of the guide rod 621 is parallel to the axial direction of the sliding sleeve 6111, and the lower end of the guide rod 621 is provided with an anti-slip ring 622. The guide rod 621 is sleeved with a first return spring 6211 fixedly connected to the sliding sleeve 6111 and the sleeve 62. When the pressure-applying portion 613 presses the pressure-receiving portion 612, the first return spring 6211 is in a compressed state.

[0054] When the copper wire 2 enters the water-blocking assembly 6, the pressure structure 611 starts to work. The sliding sleeve 6111 moves upward under the drive of the pressure driver 6112, and the pressure portion 613 on the sliding sleeve 6111 passes through the pressure-receiving portion 612 of the water-blocking ring 61. The pressure portion 613 is the portion extending inward on the sliding sleeve 6111 and contacts the outer wall of the water-blocking ring 61. As the sliding sleeve 6111 rises, the pressure portion 613 gradually squeezes the pressure-receiving portion 612, so that the water-blocking ring 61 is subjected to uniform pressure from the outside to the inside, so that the water-blocking ring 61 tightly wraps the copper wire 2. Not only is the friction between the water-blocking ring 61 and the copper wire 2 enhanced, but the effect of the water-blocking ring 61 absorbing moisture is also further improved.

[0055] When the pressure-applying part 613 presses the pressure-receiving part 612, the first return spring 6211 is in a compressed state and stores elastic potential energy. When the electromagnet is powered off and the magnetic force disappears, the first return spring 6211 releases the stored elastic potential energy and pushes the sliding sleeve 6111 to return downward, thereby releasing the squeezing of the water blocking ring 61.

[0056] See also Figure 6-Figure 9 As shown, the pressure-applying portion 613 is a block-shaped structure, the pressure-receiving portion 612 is a spherical structure, and the upper end of the pressure-applying portion 613 has an inclined surface 6131 that can smoothly pass through the pressure-receiving portion 612 .

[0057] When the sliding sleeve 6111 moves upward, the inclined surface 6131 of the pressure-applying portion 613 gradually contacts the spherical pressure-receiving portion 612 of the water-blocking ring 61. Due to the existence of the inclined surface 6131, the pressure-applying portion 613 can pass smoothly when contacting the pressure-receiving portion 612, avoiding sudden impact and jamming. As the sliding sleeve 6111 continues to rise, the pressure-applying portion 613 gradually squeezes the pressure-receiving portion 612, so that the water-blocking ring 61 is subjected to uniform pressure from the outside to the inside, thereby tightly wrapping the copper wire 2.

[0058] See also Figure 6-Figure 8 and Fig.10 As shown, an extrusion tube 632 capable of extruding the water blocking ring 61 downward is coaxially provided on the upper half of the sleeve 62, and the sleeve 62 is provided with an extrusion driver 633 for driving the extrusion tube 632 to move. The extrusion tube 632 is located above the water blocking ring 61. When the extrusion tube 632 moves downward, the water blocking ring 61 is in a stretched state, so that the water in the water blocking ring 61 is squeezed into the drainage groove 63.

[0059] The extrusion driver 633 is specifically an electromagnetic drive structure, which uses the magnetic field generated by the electromagnet to interact with the magnetic material in the extrusion tube 632 to generate magnetic force. When the electromagnet is energized, the generated magnetic field causes the extrusion tube 632 to be acted upon by the magnetic force, thereby pushing the extrusion tube 632 to move along a predetermined path. By controlling the current intensity and direction of the electromagnet, the moving speed of the extrusion tube 632 can be accurately adjusted to achieve the water extrusion of the water blocking ring 61.

[0060] The extrusion tube 632 is sleeved with a second return spring 6321 which is fixedly connected to the extrusion tube 632 and the sleeve 62. When the extrusion tube 632 extrudes the water blocking ring 61, the second return spring 6321 is in a compressed state.

[0061] When squeezing the water in the water blocking ring 61, the squeezing driver 633 is activated to push the squeezing tube 632 to move downward along a predetermined path. The water blocking ring 61 is subjected to uniform pressure from the inside to the outside, so that the water blocking ring 61 is stretched open and the water inside the water blocking ring 61 is squeezed out. The water flows along the inner wall of the water blocking ring 61 to the bottom thereof, and then enters the drainage groove 63 located below the water blocking ring 61.

[0062] When the electromagnet is powered off and the magnetic force disappears, the second return spring 6321 releases the stored elastic potential energy to push the extrusion tube 632 to return upward and return to the initial state.

[0063] See also Figure 6-Figure 8 As shown, the inner diameters of the extrusion tube 632 and the drainage groove 63 are both larger than the diameter of the copper wire 2 .

[0064] During the winding process of the copper wire 2, the copper wire 2 is in flexible contact with the water blocking ring 61. The inner diameters of the extrusion tube 632 and the drainage groove 63 are both larger than the diameter of the copper wire 2, in order to prevent the surface of the copper wire 2 from being scratched due to hard contact.

[0065] See also Figure 4-Figure 7 As shown, the air-drying component 7 includes an air outlet pipe 71 arranged at the upper end of the sleeve 62 for the copper wire 2 to pass through, and a downwardly inclined air inlet hole 711 is opened on the tube wall of the air outlet pipe 71 facing the direction of the copper wire 2, and a plurality of the air inlet holes 711 are opened around the air outlet pipe 71.

[0066] When the copper wire 2 enters the air outlet pipe 71, the air flow system inside the air outlet pipe 71 starts to work. The air inlet 711 on the air outlet pipe 71 is connected to the external air flow system. The air inlet 711 opened on the pipe wall of the air outlet pipe 71 allows the air flow to act on the surface of the copper wire 2 in an inclined downward manner, rather than blowing vertically to the copper wire 2. The direction of the air flow is opposite to the moving direction of the copper wire 2, preventing moisture from re-attaching to the dried part of the copper wire 2.

[0067] When the airflow enters the air outlet pipe 71 through the air inlet holes 711, the airflow forms a uniform airflow field inside the air outlet pipe 71. Since the air inlet holes 711 are evenly distributed around the air outlet pipe 71, the contact area between the airflow and the surface of the copper wire 2 is increased, thereby improving the drying efficiency.

[0068] See also Figure 3-Figure 7 As shown, a heating wire 72 is fixedly provided inside the air outlet pipe 71 in the form of spiral winding along its axial direction, a speed sensor 41 is provided on the upper guide wheel 4, and a controller for controlling the power of the heating wire 72 is provided on the air outlet pipe 71. The speed sensor 41 is electrically connected to the controller. When the speed of the copper wire 2 increases, the speed of the upper guide wheel 4 increases accordingly, so that the heat output of the heating wire 72 is in a state of synchronous increase.

[0069] The controller is not shown in the figure.

[0070] When the airflow enters the air outlet duct 71 through the inclined air inlet 711, the inclination direction of the airflow is opposite to the moving direction of the copper wire 2, so that the airflow can continuously push the moisture on the surface of the copper wire 2 downward, avoiding the re-attachment of moisture to the dried part of the copper wire 2.

[0071] At the same time, the heating wire 72 inside the air outlet pipe 71 starts to work and generates heat. After the airflow passes through the heating wire 72, the formed hot airflow acts on the copper wire 2, thereby improving the drying effect.

[0072] During the start-up process of the heating wire 72, the speed sensor 41 on the upper guide wheel 4 detects the moving speed of the copper wire 2 and transmits the signal to the controller. The controller adjusts the power of the heating wire 72 according to the signal of the speed sensor 41, so that the heat output of the heating wire 72 increases synchronously with the moving speed of the copper wire 2. When the moving speed of the copper wire 2 increases, the heat output of the heating wire 72 increases, ensuring that the moisture on the surface of the copper wire 2 can evaporate quickly.

[0073] See also Figure 4-Figure 7 As shown, a rubber sleeve 712 is fixedly provided at the upper end of the air outlet pipe 71 for the copper wire 2 to pass through and closely adhere to it, a movable gap is left between the lower end of the air outlet pipe 71 and the upper end of the sleeve 62, and an elastic connector 713 is fixedly connected between the air outlet pipe 71 and the sleeve 62.

[0074] The elastic connector 713 may be a spring structure, or other flexible structures such as a bellows, a joint, etc., so that the air outlet pipe 71 and the sleeve 62 are flexibly connected, allowing the sleeve 62 to move freely within a certain range and follow the deviation of the copper wire 2.

[0075] The present invention realizes efficient drying of the copper wire 2 through the synergistic effect of the water blocking component 6 and the air drying component 7.

[0076] First, the copper wire 2 passes through the water-blocking assembly 6 during movement. The water-blocking ring 61 is made of a sponge material with good water absorption and elasticity. The pressure structure 611 causes it to deform under pressure, tightly wrapping the copper wire 2, ensuring effective separation of water without wearing the copper wire 2. The separated water flows into the drainage groove 63 through the bottom of the water-blocking ring 61, and then is discharged through the drain port 631, realizing effective recovery and discharge of water, and avoiding the situation where the water scraped off the surface of the copper wire 2 keeps dripping.

[0077] Subsequently, the copper wire 2 enters the air drying assembly 7, and a high-speed airflow is blown toward the surface of the copper wire 2 from an angle opposite to the moving direction of the copper wire 2, completely drying the remaining moisture and effectively preventing the moisture from reattaching. The entire process ensures the uniformity and thoroughness of drying, improves the drying effect, and ensures the quality of the copper wire 2.

[0078] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
