Description

Technical Field

[0001] This utility model relates to the field of wire production and processing technology, and in particular to a cooling device for ultra-fine wire insulation layer. Background Technology

[0002] In the production of ultra-fine wire insulation, cooling and drying are key steps. Traditional cooling devices typically include cooling water tanks and air knife drying equipment: after the wire passes through the cooling water tank, a large amount of water stains remain on the surface, and then it is directly dried by a ring air knife.

[0003] However, due to the large amount of water stains on the surface of the insulation layer and their uneven distribution, relying solely on air knife drying is inefficient and easily leaves water residue, affecting the quality and service life of the insulation layer. Existing technologies lack effective pretreatment drying mechanisms, resulting in incomplete drying and increased energy consumption and production time.

[0004] To address this issue, we propose a cooling device for ultra-fine wire insulation. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for ultra-fine wire insulation layers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling device for ultra-fine wire insulation includes a cooling water tank and a cooling water reservoir. A drying platform is located at the tail end of the cooling water tank. Both the cooling water tank and the drying platform are equipped with several rotating guide rollers. An annular air knife is also installed on the drying platform. Two sets of alternating water-wiping assemblies are also installed on the drying platform, positioned between the annular air knife and the cooling water tank. Each water-wiping assembly includes a frame in which a double-ended screw is rotatably mounted. A motor is mounted outside the frame. Movable blocks are symmetrically mounted on the two oppositely helical sections of the double-ended screw, and hangers are fixed to the movable blocks. A flat plate is mounted on one end of the hanger extending below the frame. A slider is fixed to the outer end of the flat plate. A slide rail is vertically slidably connected inside the slider, and a pressure plate is fixed to the bottom end of the slide rail. A sponge cylinder is rotatably mounted between the pressure plate and the flat plate, and a roller is rotatably mounted at the bottom of the pressure plate. A ramp plate with a gradually increasing height is located below the roller.

[0008] In a further embodiment, a timer and a controller are installed on the outer wall of the drying table, and the controller is electrically connected to the motors of the two sets of wiping components.

[0009] In a further embodiment, a ranging sensor is also installed on the movable block, and the ranging sensor is electrically connected to the controller.

[0010] In a further embodiment, both the pressure plate and the flat plate have protruding rods fixed to their opposite surfaces, and the sponge tube is sleeved on the outside of the protruding rods.

[0011] In a further embodiment, an anti-detachment block is fixed to the top of the slide rail.

[0012] In a further embodiment, a circulation pump is installed outside the cooling water tank, and a circulation pipe extending into the cooling water tank is connected to the circulation pump.

[0013] In a further embodiment, the bottom plate of the drying table near the cooling water tank is tilted towards the cooling water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features two sets of alternating water-wiping components located between the annular air knife and the cooling water tank. First, the sponge tube wipes away most of the water stains, reducing the burden on the air knife, significantly improving drying efficiency, and reducing water residue. The water-wiping components use a double-headed screw to drive the movable block, achieving precise positioning around the wire when close, and when away, guided by the ramp plate, the pressure plate gradually moves upward towards the flat plate to squeeze the sponge tube, making it easier to squeeze out the water inside the sponge tube and ensuring its water absorption capacity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A cooling device for ultra-fine wire insulation includes a cooling water tank 1, a cooling water container 2, a drying table 3, a guide roller 5, and an annular air knife 4. After the wire insulation is extruded, it is directly fed into the cooling water tank 1, where the wire is cooled by immersing it in cooling water. The cooling water container 2 stores the cooling water and is located below the cooling water tank 1. The cooling water tank 1 has openings at both ends, allowing the cooling water to overflow and flow into the cooling water container 2. A circulation pump 24 is installed outside the cooling water container 2, which pumps water from the cooling water container 2 into the cooling water tank 1 through a circulation pipe 25, thus achieving cooling water circulation and saving resources.

[0025] The drying table 3 is located at the end of the cooling water tank 1. It has several rotating guide rollers 5 inside to guide the movement of the wire. An annular air knife 4 is installed on the drying table 3. The wire passes through the annular air knife 4. The annular air knife 4 is connected to a compressed air source through an air pipe to finally dry the wire. The bottom plate of the drying table 3 near the cooling water tank 1 is inclined towards the cooling water tank 2 to facilitate the drainage of residual water into the cooling water tank 2.

[0026] Two sets of water-wiping assemblies 6 are installed on the drying table 3, located between the annular air knife 4 and the cooling water tank 1. Each set of water-wiping assemblies 6 includes a frame 7, which is supported horizontally on the drying table 3 by a support rod. A double-ended screw 8 is rotatably installed in the frame 7. A motor 9 is installed on the outer wall of one end of the frame 7, and the motor 9 drives the double-ended screw 8 to rotate. A movable block 10 is symmetrically installed on the two oppositely helical threads of the double-ended screw 8. The movable block 10 is threadedly connected to the double-ended screw 8, and the bottom of the movable block 10 is slidably connected to the bottom plate of the frame 7. A hanger 11 is fixed on the moving block 10. The lower end of the hanger 11 extends to the bottom of the frame 7 and is equipped with a plate 12. A slider 13 is fixed on the outer side of the plate 12. A slide rail 14 is vertically slidably connected inside the slider 13. A pressure plate 15 is fixed at the bottom of the slide rail 14. A sponge tube 16 is rotatably installed between the pressure plate 15 and the plate 12 for wiping the wire. When the motor 9 is working, the two plates 12 can be precisely controlled to move closer or further away from each other, so that the sponge tube 16 below can be precisely clamped on both sides of the wire or moved away from the wire.

[0027] A roller 17 is rotatably mounted on the bottom of the pressure plate 15. A ramp 18 is provided below the roller 17. The height of the ramp 18 gradually increases outward. When the roller 17 moves outward with the pressure plate 15, it is forced to rise during the movement because the roller 17 is in continuous contact with the slope of the ramp 18. The rising action is transmitted through the pressure plate 15 and the slide rail 14, forcing the pressure plate 15 to move upward and close to the plate 12. Thus, together with the plate 12, the pressure plate 15 is squeezed from both sides of the sponge cylinder 16, squeezing out the cooling water absorbed inside. The squeezed water flows into the bottom plate of the drying table 3, realizing the automatic dehydration of the sponge cylinder 16, so that it can restore its strong water absorption capacity in the next operation.

[0028] Furthermore, a protruding rod 22 is fixed on the opposite side of the pressure plate 15 and the flat plate 12, and the sponge tube 16 is sleeved on the protruding rod 22 for easy installation and replacement. An anti-detachment block 23 is fixed at the top of the slide rail 14 to prevent the slider 13 from falling out and to ensure safe operation.

[0029] A timer 19 and a controller 20 are installed on the outer wall of the drying table 3. The controller 20 is electrically connected to the motors 9 of the two sets of wiping components 6, and controls them to work alternately after the timer 19 is triggered. This ensures that while one set of wiping components 6 is performing dehydration, the other set of wiping components 6 can absorb water and dry the wires, thus ensuring the continuity of work. A distance sensor 21 is installed on the movable block 10 and is electrically connected to the controller 20. It is used to monitor the distance the movable block 10 moves, so as to accurately locate the moving position of the sponge cylinder 16.

[0030] Workflow: The wire passes through the cooling water tank 1 to complete the initial cooling, and then enters the drying table 3. It is guided forward by the guide roller 5. The controller 20 starts the motor 9 of the A group wiping component 6 according to the setting of the timer 19. The motor 9 drives the double-headed screw 8 to move the two movable blocks 10 towards each other, which drives the two sponge cylinders 16 to close from both sides, gently and tightly clamping the wire. The sponge cylinders rotate with the movement of the wire, wiping away most of the surface moisture.

[0031] When the A group of water wiping components 6 is working, the B group of water wiping components 6 is in a non-working position. At this time, the roller 17 of the B group is resting on the high position of its corresponding ramp plate 18, and its sponge cylinder 16 is in a squeezed state, and the internal water has been discharged.

[0032] When the working time of Group A reaches the preset value, the controller 20 issues a command to first control the sponge cylinder 16 of the water wiping component 6 of Group B to contact the wire, and then control the motor 9 of Group A to reverse, driving the two movable blocks 10 to move in opposite directions, so that the sponge cylinder 16 of Group A leaves the wire. During the removal process, the roller 17 of Group A rolls onto the ramp plate 18, the pressure plate 15 is lifted, and the sponge cylinder 16 is automatically squeezed and dehydrated, preparing for the next work. This cycle continues, with the two groups of water wiping components 6 alternating between "working" and "dehydration maintenance", realizing uninterrupted continuous production and self-maintenance of the wiping parts. After most of the water stains are removed by the water wiping component 6, the wire is then finally dried by the annular air knife 4, completing the entire cooling and drying process.
