[0002] Enameled wire is a winding wire composed of a conductor (such as copper, aluminum or alloy) and an insulating layer (insulating varnish). It is softened by annealing the bare wire, painted multiple times, and baked to form a wire with both conductivity and insulation. When the enameled wire is produced, it is necessary to coat the surface of the conductor with insulating varnish. After painting, it is cooled, which can quickly solidify and shape the insulating varnish, forming a uniform and dense insulating layer on the surface of the conductor, thereby ensuring that the enameled wire has good insulation properties and preventing electrical faults such as short circuits during use.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the cooperation of the first annular groove and other parts, the water inside the water storage tank flows into the inner sides of the first annular groove, the second annular groove and the third annular groove along the first connecting pipe, thereby cooling the enameled wire respectively. Since the distances of the first annular groove, the second annular groove and the third annular groove from the inner side of the enameled wire are successively reduced, the temperature in contact with the enameled wire is successively reduced, thereby increasing the cooling effect on the enameled wire successively. When the water flows into the outer wall of the enameled wire through the water hole, the cooling effect of the device is further increased by contacting with the enameled wire, thereby realizing step-by-step cooling of the enameled wire, preventing thermal stress cracks caused by sudden cooling of the paint film of the enameled wire due to a sudden drop in temperature, and at the same time, the paint layer can make the surface of the enameled wire evenly solidified, thereby improving its scratch resistance, thereby improving the overall practicality of the device; 2. By arranging the cooperation of parts such as water storage tanks, multiple water storage tanks are arranged horizontally on the top of the fixed plate, and the temperature inside the multiple water storage tanks decreases successively. Since the temperature of the enameled wire just entering the inside of the first fixed tube is the highest, and the water temperature inside the multiple groups of water storage tanks decreases successively compared with the enameled wire, when the enameled wire passes through the inner sides of the multiple groups of first fixed tubes successively, it can be cooled by the water with gradually decreasing temperature successively, thereby further reducing the thermal stress on the surface of the enameled wire, effectively reducing the generation of cracks on the surface of the enameled wire, and at the same time improving the overall cooling effect of the device, thereby improving the overall practicality of the device; 3. By setting the cooperation of parts such as hydraulic cylinders, the output end of the hydraulic cylinder drives the round rod to move up and down reciprocatingly. When the round rod is driven to move downward, the driving block is driven downward under the action of the round rod, thereby driving a spur rack to move downward. At this time, the spur gear is driven to rotate under the action of one spur rack, thereby driving another spur rack to move upward, thereby driving one driving ring to move upward and the other driving ring to move downward, thereby tightening the enameled wire. When the round rod is reset, the enameled wire gradually becomes loose under the action of the driving ring, so that the enameled wire is located between the two hoses in a wave-like reciprocating tightening operation, thereby realizing the continuous tightening and relaxation of the enameled wire, so that when the cooling water cools the enameled wire, the surface tension of the enameled wire is increased, making it easier for the cooling water to penetrate into the gap between the paint film and the conductor, thereby improving the heat exchange efficiency. At the same time, periodically tightening and releasing the enameled wire can dynamically adjust the surface tension of the enameled wire, reduce the tensile deformation of the paint film caused by the fluctuation of tension, thereby improving the overall practicality of the device; 4. By setting up an automatic air supply component, the gas can enter the inner side of the first fixed tube from the water hole, thereby generating bubbles. Under the guidance of the water pump, the gas can move along the two bent hoses. In the process of the bubbles rising and flowing in the water, the surrounding water flow will be disturbed, breaking the laminar state of the water and forming a stronger convection. This convection can speed up the speed of heat transfer from the surface of the enameled wire to the cooling water, thereby significantly improving the heat exchange efficiency. Compared with simple water flow cooling, the cooling process with the participation of bubbles can make the enameled wire cool down faster, reduce the cooling time, and improve production efficiency. The bubbles in When flowing in water, it will have a certain scouring effect on the surface of the enameled wire. This scouring can remove impurities, paint residues and other tiny particles that may exist on the surface of the enameled wire, making the surface of the enameled wire cleaner. A clean surface is conducive to the uniform curing of the paint layer and reduces paint layer defects caused by surface impurities, thereby improving the quality and appearance of the enameled wire. The tiny impact force generated when the bubbles burst on the surface of the enameled wire can also promote the discharge of tiny bubbles or gaps inside the paint film, which helps to reduce defects inside the paint film, improve the density and integrity of the paint film, and thus improve the electrical and mechanical properties of the enameled wire, such as voltage resistance and scratch resistance.

The second hose 22 is fixedly connected to another first fixed pipe 5, and the first annular groove 7, the second annular groove 8 and the third annular groove 9 are interconnected. The step cooler also includes a fixed plate 3 fixedly connected to the outer wall of the first connecting strip 2, and a water tank 13 is fixedly connected to the top of the fixed plate 3. A water pump 15 is installed at the water inlet of the water tank 13, and a second connecting pipe 16 is fixedly connected to the water inlet of the water pump 15, and one end of the second connecting pipe 16 is connected to the water outlet of the second hose 22. A first connecting pipe 14 is fixedly connected to the water outlet of the water tank 13, and one end of the first connecting pipe 14 passes through the inner side of the first annular groove 7. A relief valve 17 is installed at the air outlet of the water tank 13. A water groove 18 communicating with the third annular groove 9 is provided on the inner side of the first fixed pipe 5, and a plurality of water holes 19 communicating with the water groove 18 are provided inside the first fixed pipe 5; A heater is provided inside the water tank 13. Since how the heater heats is a prior art, it is not described in detail in this solution. The heater can heat the water inside the water tank 13. The water tank 13 is connected to an external water supply pipe. First, when the staff cools the enameled wire 6, the external water supply pipe inputs water into the inside of the water tank 13, and the heater inside the water tank 13 heats the water inside the water tank 13. At this time, the water inside the water tank 13 flows along the first connecting pipe 14 into the inside of the first annular groove 7, the second annular groove 8, and the third annular groove 9, thereby cooling the enameled wire 6 respectively. The distances between the first annular groove 7, the second annular groove 8, and the third annular groove 9 and the inner side of the enameled wire 6 are reduced, so that the temperature in contact with the enameled wire 6 is reduced successively, thereby increasing the cooling effect on the enameled wire 6 successively, and when water flows into the outer wall of the enameled wire 6 through the water hole 19, the water further increases the cooling effect of the device by contacting the enameled wire 6, thereby realizing step-by-step cooling of the enameled wire 6, preventing thermal stress cracks caused by sudden temperature drop in the paint film of the enameled wire 6 due to sudden cooling, and at the same time making the paint layer uniformly solidify the surface of the enameled wire 6, thereby improving its scratch resistance, thereby improving the overall practicality of the device; A plurality of water tanks 13 are arranged horizontally on the top of the fixed plate 3, and the temperature inside the plurality of water tanks 13 decreases successively. Since the temperature of the enameled wire 6 just entering the inner side of the first fixed tube 5 is the highest, and the water temperature inside the plurality of water tanks 13 decreases successively compared with the enameled wire 6, when the enameled wire 6 passes through the inner sides of the plurality of first fixed tubes 5 successively, it can be cooled by the water with gradually decreasing temperature successively, thereby further reducing the thermal stress on the surface of the enameled wire 6, effectively reducing the generation of cracks on the surface of the enameled wire 6, and at the same time improving the overall cooling effect of the device, thereby improving the overall practicality of the device.

[0019] The water pump 15 is controlled by a PLC controller, which can control the intermittent start of the water pump 15. When the enameled wire 6 is cooled, the PLC controller controls the start of the enameled wire 6, and the output end of the enameled wire 6 is started. When the waste water on the outer wall of the enameled wire 6 flows into the inner side of the second hose 22, the waste water on the inner side of the second hose 22 is sucked under the suction force on the inner side of the second connecting pipe 16, so that the waste water on the surface of the enameled wire 6 can be treated, and the waste water is heated again by the heater on the inner side of the water storage tank 13, so that it flows back into the inner side of the first annular groove 7, the second annular groove 8, and the third annular groove 9, and the enameled wire 6 is cooled again, thereby effectively saving water resources. At the same time, the water is continuously circulated, thereby improving the cooling effect of the device, improving the cooling efficiency of the enameled wire 6, and thereby improving the overall practicality of the device.

[0020] See also Figure 6 to Figure 8The reciprocating tensioning mechanism is located between the first fixed tube 5 and the enameled wire 6 and is used to tighten the enameled wire 6. The reciprocating tensioning mechanism includes a second connecting strip 23 fixedly connected to the bottom of the fixed plate 3. The bottom of the second connecting strip 23 is fixedly connected to a rectangular plate 24. A hydraulic cylinder 27 is installed on the top of the rectangular plate 24. The output end of the hydraulic cylinder 27 passes through the bottom of the rectangular plate 24 and is fixedly connected to a driving block 29. A straight rack 30 is fixedly connected to one side of the driving block 29. A connecting rod 34 is fixedly connected to one side of the straight rack 30. The connecting rod A sliding rod 25 is fixedly connected to one side of the rectangular plate 24, and the sliding rod 25 is slidably connected to the inner side of the rectangular plate 24. A driving ring 26 is fixedly connected to the bottom of the sliding rod 25, and the driving ring 26 is fixedly connected to the hose 20. The reciprocating tensioning mechanism also includes a connecting seat 31 fixedly connected to the bottom of the rectangular plate 24, and a rotating shaft 32 is rotatably connected to the inner side of the connecting seat 31. A spur gear 33 is fixedly connected to the outer wall of the rotating shaft 32. Two spur racks 30, sliding rod 25, and driving ring 26 are provided. The two spur racks 30 are meshed with the spur gear 33. The hose 20 and the second fixed pipe 21 are initially arranged in an offset arrangement of one up and one down. The hydraulic cylinder 27 is controlled by a PLC controller, and the hydraulic cylinder 27 can be controlled to start intermittently. When the cooling water enters the outer wall of the enameled wire 6 through the inner side of the water hole 19 to cool it, the PLC controller controls the hydraulic cylinder 27 to start, and the output end of the hydraulic cylinder 27 drives the round rod 28 to move up and down. When the round rod 28 is driven to move downward, the driving block 29 is driven to move downward under the action of the round rod 28, thereby driving a spur rack 30 to move downward. At this time, the spur gear 33 is driven to rotate under the action of one spur rack 30, thereby driving the other spur rack 30 to move upward, thereby driving a driving ring 26 respectively. When the round rod 28 is reset, the enameled wire 6 gradually becomes loose under the action of the driving ring 26, so that the enameled wire 6 is located between the two hoses 20 and is tightened in a wave-like manner, thereby realizing continuous tightening and loosening of the enameled wire 6. When the cooling water cools the enameled wire 6, the surface tension of the enameled wire 6 is increased, so that the cooling water can more easily penetrate into the gap between the paint film and the conductor, thereby improving the heat exchange efficiency. At the same time, the periodic tightening and releasing of the enameled wire 6 can dynamically adjust the surface tension of the enameled wire 6 and reduce the tensile deformation of the paint film caused by the fluctuation of tension, thereby improving the overall practicality of the device.

The second one-way valve 37 and the first one-way valve 12 are both one-way air-permeable valves. When a spur rack 30 located on the left side of the spur gear 33 moves upward, it can drive a piston plate 36 to move upward, thereby rushing the other gas inside a rectangular box 35 into the first exhaust pipe 10, so that the first exhaust pipe 10 rushes the gas into the channel located between the two hoses 20, and the second one-way valve 37 located on the side of the first exhaust pipe 10 will not take in air. When the above steps are reversed, air is taken in through the second one-way valve 37 inside a rectangular box 35, and the gas inside the other rectangular box 35 can enter the second exhaust pipe 11, so that the gas can enter the inner side of the first fixed pipe 5 from the water hole 19, thereby generating bubbles, which can move along the two bent hoses 20 under the guidance of the suction of the water pump 15. In the process of rising and flowing in the water, the bubbles will cause the surrounding water flow to be disturbed, breaking the water layer. Flow state, forming a stronger convection, this convection can speed up the speed of heat transfer from the surface of the enameled wire 6 to the cooling water, thereby significantly improving the heat exchange efficiency. Compared with simple water flow cooling, the cooling process with the participation of bubbles can make the enameled wire 6 cool down faster, reduce the cooling time, and improve production efficiency. When the bubbles flow in the water, they will have a certain scouring effect on the surface of the enameled wire 6. This scouring can remove impurities, paint residues and other tiny particles that may exist on the surface of the enameled wire 6, making the surface of the enameled wire 6 cleaner. The clean surface is conducive to the uniform curing of the paint layer and reduces the defects of the paint layer caused by surface impurities, thereby improving the quality and appearance of the enameled wire 6. The tiny impact force generated when the bubbles rupture on the surface of the enameled wire 6 can also promote the discharge of tiny bubbles or gaps inside the paint film, which helps to reduce the defects inside the paint film, improve the density and integrity of the paint film, and then improve the electrical and mechanical properties of the enameled wire 6, such as voltage resistance and scratch resistance.
