Description

Technical Field

[0001] This application relates to the technical field of enameled wire, and in particular to self-lubricating 200-grade polyamide-imide composite enameled copper round wire and its production apparatus. Background Technology

[0002] Enameled wire is a major type of electrical product, consisting of two layers: a bare wire and a coated wire. The bare wire is annealed and softened, then coated multiple times and baked. Enameled wire is a primary raw material for motors, electrical appliances, and household appliances. In recent years, the power industry has experienced sustained and rapid growth, and the rapid development of household appliances has broadened the application scope of enameled wire, leading to higher demands from users.

[0003] In the production process of enameled wire, the heated copper wire is cooled. Therefore, the production equipment for enameled wire includes a cooling device for cooling the copper wire. Conventional cooling devices use cooling water to cool the copper wire. However, during the heating process, impurities will be generated on the surface of the copper wire. Therefore, after a period of use, the cooling water is prone to contain a lot of impurities, and the operator needs to replace the cooling water to clean the impurities.

[0004] Regarding the aforementioned related technologies, the inventors believe that when operators find a large number of impurities in the cooling water during the copper wire production process, in order to ensure the quality of the copper wire, the operators need to replace the cooling water in the cooling device. At this time, the cooling device cannot be used for the copper wire cooling process, which may affect the copper wire production efficiency. Summary of the Invention

[0005] To ensure the production efficiency of copper wire, this application provides self-lubricating 200-grade polyamide-imide composite enameled copper round wire and its production apparatus.

[0006] The production apparatus for self-lubricating grade 200 polyamide-imide composite enameled copper round wire provided in this application adopts the following technical solution:

[0007] A production apparatus for self-lubricating 200-grade polyamide-imide composite enameled copper round wire includes a base and a cooling tank disposed on the base for containing cooling water. The cooling tank is provided with a partition, which divides the cooling tank into a first cooling zone and a second cooling zone. The cooling tank is rotatably connected to the base. A rotating component for driving the cooling tank to rotate is provided on the base. Cleaning components for removing impurities are provided in both the first and second cooling zones. A support is provided on the base, and a lifting component for controlling the height of the copper wire is provided on the support.

[0008] By adopting the above technical solution, the operator uses the lifting component to move the heated copper wire to the first cooling zone. The cooling water in the first cooling zone can continuously cool the heated copper wire. When the operator finds that there are many impurities in the cooling water in the first cooling zone, the operator first uses the lifting component to move the heated copper wire out of the cooling box. Then, the operator starts the rotating component to exchange positions between the first and second cooling zones. Then, the operator uses the lifting component to move the heated copper wire to the cooling water in the second cooling zone, thereby ensuring the production efficiency of the copper wire. At the same time, the operator uses the cleaning component to clean the impurities in the first cooling zone, thereby ensuring that there are no impurities in the cooling water in the first cooling zone when the positions of the first and second cooling zones are exchanged next time.

[0009] Preferably, the rotating assembly includes a drive motor fixedly connected to the base, a drive gear fixedly sleeved on the output shaft of the drive motor, and an external gear ring fixedly sleeved on the cooling box, wherein the drive gear and the external gear ring mesh with each other.

[0010] By adopting the above technical solution, the operator starts the drive motor, the output shaft of the drive motor rotates, which drives the drive gear to rotate, the drive gear to rotate, and the rotation of the outer gear ring to rotate the cooling box, thereby realizing the exchange of positions between the first cooling zone and the second cooling zone, thus ensuring the production efficiency of copper wire.

[0011] Preferably, the cleaning assembly includes a reciprocating screw rotatably mounted on the bottom surface of the cooling box, a mounting ring sleeved on the reciprocating screw, and a scraper detachable from the mounting ring. The mounting ring is threadedly engaged with the reciprocating screw. One side of the scraper slides against the inner wall of the cooling box, and the other side slides against the partition. The scraper has water-permeable holes, and a filter membrane for filtering impurities is fixedly connected to the scraper. A drive assembly for driving the reciprocating screw to rotate is provided on the base.

[0012] By adopting the above technical solution, the operator uses the drive assembly to rotate the reciprocating screw. The rotation of the reciprocating screw drives the mounting ring to move back and forth along the length of the reciprocating screw. The movement of the mounting ring drives the scraper to move back and forth along the length of the reciprocating screw. The cooperation between the scraper and the baffle helps to limit the rotation of the scraper. The setting of the water permeable hole and the filter membrane is conducive to filtering impurities, thereby ensuring that the impurities are located above the scraper. When the operator moves the scraper above the cooling water, the operator replaces the scraper, which makes it convenient for the operator to remove impurities.

[0013] Preferably, the base has a receiving groove for accommodating the cooling box, and the driving assembly includes a rotating gear fixedly sleeved on the reciprocating screw extending to the inner end of the cooling box and an internal gear ring installed on the inner sidewall of the receiving groove. The rotating gear is rotatably engaged with the cooling box, and part of the rotating gear is located outside the cooling box. The rotating gear meshes with the internal gear ring.

[0014] By adopting the above technical solution, when the operator rotates the cooling box by rotating the component, the rotation of the cooling box drives the rotating gear to rotate around the axis of the cooling box. At the same time, the cooperation between the internal gear ring and the rotating gear causes the rotating gear to rotate on its own axis. The rotation of the rotating gear drives the reciprocating screw to rotate, thereby realizing the scraper to move back and forth along the length direction of the reciprocating screw.

[0015] Preferably, a movable seat is slidably disposed on the base, and a movable groove is provided on the base for sliding cooperation with the movable seat. A lead screw is inserted inside the base and is rotatably connected to the base. The lead screw passes through the movable seat and is threadedly engaged with the movable seat. A handwheel is fixedly connected to the end of the lead screw extending from the base.

[0016] By adopting the above technical solution, the operator turns the handwheel, which drives the lead screw, and the lead screw drives the moving seat to move along the moving groove, thereby facilitating the operator to adjust the position of the drive gear and thus control the rotation of the cooling box.

[0017] Preferably, a connecting sleeve is fixedly connected to the mounting ring, and a connecting ring is provided on the scraper. The outer circumferential surface of the connecting sleeve is threadedly engaged with the inner sidewall of the connecting ring.

[0018] By adopting the above technical solution, the connection sleeve and the connecting ring are designed so that the mounting ring and the scraper can be detachably connected, which makes it convenient for operators to directly replace the scraper.

[0019] Preferably, the bracket is provided with guide rollers at intervals, and a guide plate is provided between adjacent guide rollers. The lifting assembly includes a cylinder mounted on the bracket and a connecting rod fixedly connected to the piston rod of the cylinder. The connecting rod is fixedly connected to the guide plate, and a plurality of adjusting rollers for sliding cooperation with the copper wire are rotatably mounted on the guide plate.

[0020] By adopting the above technical solution, the operator starts the cylinder, the piston rod of the cylinder moves and drives the connecting rod to move, the connecting rod moves and drives the guide plate and the adjusting roller to move, thereby controlling the copper wire to enter the cooling water.

[0021] Preferably, a rotating rod is rotatably mounted on the base, one end of the rotating rod is fitted with a driven gear for meshing with the driving gear, and the other end of the rotating rod is fitted with a first bevel gear. A positioning rod is rotatably mounted on the bracket, and a second bevel gear is fixedly fitted on the positioning rod. The first bevel gear and the second bevel gear mesh with each other. A driving pulley is fitted on the positioning rod, and a driven pulley is coaxially mounted on the guide roller. A belt is fitted between the driving pulley and the driven pulley.

[0022] By adopting the above technical solution, when the operator moves the drive motor to make the driving gear and the driven gear mesh with each other, the drive motor drives the rotating rod to rotate through the cooperation of the driving gear and the driven gear. The rotating rod drives the positioning rod to rotate through the cooperation of the first bevel gear and the second bevel gear. The positioning rod drives the driving pulley to rotate. The driving pulley drives the driven pulley to rotate through the belt, thereby causing the guide roller to rotate, and finally realizing the uniform movement of the copper wire.

[0023] Preferably, a first rotating ring for communication with the cooling box is rotatably mounted at the bottom of the cooling box, and a second rotating ring for communication with the cooling box is rotatably mounted at the top of the cooling box. A water pump is provided on the base, an inlet pipe is connected to the inlet of the water pump, and an outlet pipe is connected to the outlet of the water pump. The end of the inlet pipe away from the water pump is connected to the first rotating ring of the cooling box, and the end of the outlet pipe away from the water pump is connected to the top of the second rotating ring, with the outlet opening facing the copper wire.

[0024] By adopting the above technical solution, when the operator starts the water pump, the clean cooling water at the bottom of the cooling tank passes through the first rotating ring, the inlet pipe, the outlet pipe, and the second rotating ring in sequence and enters the top of the cooling tank. The cooling water impacts the copper wire, thereby accelerating the cooling of the copper wire.

[0025] The self-lubricating 200-grade polyamide-imide composite enameled copper round wire provided in this application adopts the following technical solution:

[0026] The self-lubricating 200-grade polyamide-imide composite enameled copper round wire comprises a copper conductor and a protective layer wrapped around the copper conductor. The protective layer comprises a polyamide-imide composite enamel and a lubricating oil.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The heating copper wire is moved to the first cooling zone using a lifting assembly. The cooling water in the first cooling zone continuously cools the heating copper wire. When the operator finds that there are many impurities in the cooling water in the first cooling zone, the operator first uses the lifting assembly to move the heating copper wire out of the cooling box. Then, the operator starts the rotating assembly to exchange the positions of the first and second cooling zones. Then, the operator uses the lifting assembly to move the heating copper wire to the cooling water in the second cooling zone, thereby ensuring the production efficiency of the copper wire. At the same time, the operator uses the cleaning assembly to clean the impurities in the first cooling zone, thereby ensuring that there are no impurities in the cooling water in the first cooling zone when the positions of the first and second cooling zones are exchanged next time.

[0029] 2. The drive assembly rotates the reciprocating screw, which in turn drives the mounting ring to move back and forth along the length of the screw. This movement of the mounting ring, in turn, drives the scraper to move back and forth along the length of the screw. The cooperation between the scraper and the baffle helps to limit the scraper's rotation. The water permeable holes and the filter membrane facilitate the filtration of impurities, ensuring that the impurities are located above the scraper. When the operator moves the scraper above the cooling water, the operator can replace the scraper, making it convenient for the operator to remove impurities.

[0030] 3. The cooling box is rotated by the rotating assembly. The rotation of the cooling box drives the rotating gear to rotate around the axis of the cooling box. At the same time, the cooperation between the internal gear ring and the rotating gear causes the rotating gear to rotate on its own axis. The rotation of the rotating gear drives the reciprocating screw to rotate, thereby realizing the scraper to move back and forth along the length of the reciprocating screw.

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] This application discloses an apparatus for producing self-lubricating 200-grade polyamide-imide composite enameled copper round wire. (Refer to...) Figure 1 The production equipment for self-lubricating 200-grade polyamide-imide composite enameled copper round wire includes a base 1 and a cooling box 2.

[0041] Reference Figure 2 The base 1 is horizontally positioned, and a receiving groove 28 is formed on its upper surface, with a circular opening. The cooling box 2 is a hollow cylindrical shape, with an opening on its upper surface. The bottom surface of the cooling box 2 is rotatably connected to the inner bottom surface of the receiving groove 28. A partition 21 is fixedly connected to the inner wall of the cooling box 2, dividing the cooling box 2 into a first cooling zone 22 and a second cooling zone 23 with the same cross-sectional area. Multiple connecting holes 211 are formed at the bottom of the partition 21, arranged in a matrix, and a filter membrane 212 for filtering impurities is fixedly connected to the inner wall of the connecting holes 211.

[0042] Reference Figure 2 , Figure 3A support 11 is provided on the base 1. The support 11 includes a vertical plate 111 and a horizontal plate 112. The bottom surface of the vertical plate 111 is fixedly connected to the upper surface of the base 1, and the bottom surface of the horizontal plate 112 is fixedly connected to the upper surface of the vertical plate 111. The end of the horizontal plate 112 away from the vertical plate 111 is located above the cooling box 2. Two guide rollers 12 for guiding copper wires 9 are provided on the bottom surface of the horizontal plate, and the two guide rollers 12 are arranged at intervals. A guide plate 13 is provided between the two guide rollers 12. The guide plate 13 is arranged horizontally, and two adjusting rollers 14 are rotatably mounted on the bottom surface of the guide plate 13, and the two adjusting rollers 14 are arranged at intervals. The copper wires 9 are wound between the guide rollers 12 and the adjusting rollers 14, and the copper wires 9 slide and cooperate with the guide rollers 12 and the adjusting rollers 14 respectively.

[0043] Reference Figure 3 A lifting assembly 3 is provided on the horizontal plate 112. The lifting assembly 3 includes a cylinder 31 and a connecting rod 32. The cylinder 31 is installed on the upper surface of the horizontal plate 112, and the piston rod of the cylinder 31 passes through the horizontal plate 112 and slides with the horizontal plate 112. A connecting rod 32 is provided on the piston rod of the cylinder 31. One end of the connecting rod 32 is fixedly connected to the piston rod of the cylinder 31, and the other end of the connecting rod 32 is fixedly connected to the guide plate 13.

[0044] The operator starts cylinder 31, the piston rod of cylinder 31 drives the connecting rod 32 to move, the connecting rod 32 moves the guide plate 13 to move, the guide plate 13 drives the adjusting roller 14 and the copper wire 9 to move until the copper wire 9 is immersed in the cooling water of the cooling box 2.

[0045] Reference Figure 2 The base 1 is equipped with a rotating assembly 4 for driving the cooling box 2 to rotate. The rotating assembly 4 includes a drive motor 41, a drive gear 42, and an external gear ring 43. A movable seat 15 is slidably mounted on the upper surface of the base 1, and a movable groove 16 is formed on the upper surface of the base 1 for sliding engagement with the movable seat 15. The length direction of the movable groove 16 is consistent with the length direction of the base 1. A lead screw 17 is inserted into the base 1 and is rotatably connected to the base 1. The end of the lead screw 17 extending into the movable groove 16 passes through the movable seat 15 and is threadedly engaged with the movable seat 15. A handwheel 18 is fixedly connected to the end of the lead screw 17 extending out of the base 1. The drive motor 41 is mounted on the upper surface of the movable seat 15, and the drive gear 42 is fixedly sleeved on the output shaft of the drive motor 41. The external gear ring 43 is fixedly sleeved on the cooling box 2 and can mesh with the drive gear 42.

[0046] The operator turns handwheel 18, which in turn rotates lead screw 17. The rotation of lead screw 17 causes movable seat 15 to move along its length. This movement of movable seat 15 drives drive motor 41 until drive motor 41 engages with external gear ring 43. At this point, the operator starts drive motor 41, which in turn drives drive gear 42, causing external gear ring 43 to rotate, thus rotating cooling box 2.

[0047] Reference Figure 2 , Figure 3 A rotating rod 19 is rotatably mounted on the upper surface of the base 1. The rotating rod 19 is vertically arranged, and its upper surface is rotatably connected to the bottom surface of the horizontal plate 112. A driven gear 191 is fixedly sleeved on the bottom of the rotating rod 19, and the driven gear 191 can mesh with the driving gear 42. A first bevel gear 192 is fixedly sleeved on the upper end of the rotating rod 19. A positioning rod 113 is rotatably mounted on the side of the vertical plate 111 near the rotating rod 19. The positioning rod 113 is horizontally arranged, and a second bevel gear 114 is fixedly sleeved on the end of the positioning rod 113 near the first bevel gear 192. The first bevel gear 192 and the second bevel gear 114 mesh with each other. A driving pulley 115 is fixedly sleeved on the positioning rod 113. A driven pulley 121 is coaxially mounted on the two guide rollers 12, and a belt 116 is wound between the driving pulley 115 and the driven pulley 121.

[0048] When the operator moves the drive motor 41 until the driving gear 42 meshes with the driven gear 191, the output shaft of the drive motor 41 drives the driving gear 42 to rotate. The rotation of the driving gear 42 drives the driven gear 191 to rotate. The rotation of the driven gear 191 drives the rotating rod 19 to rotate. The rotation of the rotating rod 19 drives the first bevel gear 192 to rotate. The rotation of the first bevel gear 192 drives the second bevel gear 114 to rotate. The rotation of the second bevel gear 114 drives the positioning rod 113 to rotate. The rotation of the positioning rod 113 drives the driving pulley 115 to rotate. The driving pulley 115 drives the two driven pulleys 121 to rotate through the belt 116. The driven pulleys 121 drive the guide roller 12 to rotate, thereby making the copper wire 9 move smoothly.

[0049] Reference Figure 2 , Figure 4The base 1 is equipped with a locking assembly 5, which includes a pull rod 51, an abutment block 52, and a spring 53. The pull rod 51 passes through the base 1 and slides with it. The abutment block 52 is fixedly connected to the end of the pull rod 51 extending into the receiving groove 28, and abuts against the outer circumferential surface of the cooling box 2. A fixing block 54 is fixedly connected to the end of the pull rod 51 extending out of the base 1. A positioning groove 55 is provided in the base 1. The positioning groove 55 has a circular cross-section, and its axis coincides with the axis of the pull rod 51. The spring 53 is sleeved on the end of the pull rod 51 located in the positioning groove 55. One end of the spring 53 is fixedly connected to the pull rod 51, and the other end is fixedly connected to the inner end face of the positioning groove 55.

[0050] The operator pulls the fixing block 54, which moves the pull rod 51. The pull rod 51 then disengages the abutment block 52 from the cooling box 2. At this time, the spring 53 is compressed, allowing the operator to drive the cooling box 2 to rotate. After the cooling box 2 finishes rotating, the operator releases the fixing block 54. The pull rod 51 moves under the action of the spring 53, causing the abutment block 52 to engage with the cooling box 2, thus locking the cooling box 2 in place.

[0051] Reference Figure 2 , Figure 5 The cooling chamber 2 is equipped with two sets of cleaning components 6. One set of cleaning components 6 is located in the first cooling zone 22, and the other set is located in the second cooling zone 23. Each set of cleaning components 6 includes a reciprocating screw 61, a mounting ring 62, and a scraper 63. The reciprocating screw 61 is vertically arranged, with its bottom extending into the cooling chamber 2 and rotatably connected to it. The reciprocating screw 61 in the first cooling zone 22 and the reciprocating screw 61 in the second cooling zone 23 are symmetrically arranged about the axis of the cooling chamber 2. The mounting ring 62 is fitted onto the reciprocating screw 61, and the mounting ring 62 is threaded into the reciprocating screw 61 and slides against the inner wall of the cooling chamber 2. The scraper 63 is located on the upper surface of the mounting ring 62, and the reciprocating screw 61 passes through the scraper 63. One side of the scraper 63 slides against the partition 21, and the other side slides against the inner wall of the cooling chamber 2. The upper surface of the scraper 63 has multiple water-permeable holes 632 arranged in a matrix. The openings of the water-permeable holes 632 are circular, and a filter membrane 212 for filtering impurities is fixedly connected to the inner wall of each water-permeable hole 632.

[0052] Reference Figure 2 , Figure 5A connecting sleeve 621 is fixedly connected to the side of the mounting ring 62 near the scraper 63. The connecting sleeve 621 is sleeved on the reciprocating screw 61, and the connecting sleeve 621 and the reciprocating screw 61 are in sliding engagement. A connecting ring 631 is fixedly connected to the side of the scraper 63 near the mounting ring 62. The connecting ring 631 is sleeved on the connecting sleeve 621, and the inner wall of the connecting ring 631 is threadedly engaged with the outer wall of the connecting sleeve 621. The connection sleeve 621 and the connecting ring 631 allow the mounting ring 62 and the scraper 63 to be detachably connected, thereby facilitating the operator to replace the scraper 63.

[0053] When the scraper 63 of the first cooling zone 22 is at its lowest point, the scraper 63 of the second cooling zone 23 is at its highest point. While the first cooling zone 22 is used to cool the copper wire 9, the operator can easily replace the scraper 63 in the second cooling zone 23. When there are many impurities in the cooling water in the first cooling zone 22, the operator can exchange the first cooling zone 22 and the second cooling zone 23 by rotating the cooling box 2.

[0054] Reference Figure 2 , Figure 4 The base 1 is equipped with a drive assembly 7 for driving the reciprocating lead screw 61 to rotate. The drive assembly 7 includes a rotating gear 71 and an internal gear ring 72. The rotating gear 71 is sleeved on the end of the reciprocating lead screw 61 located on the inner bottom surface of the cooling box 2, and part of the rotating gear 71 is located outside the cooling box 2. There are two rotating gears 71, and the two rotating gears 71 correspond one-to-one with the two reciprocating lead screws 61. The cooling box has two notches 73 for accommodating the rotating gears 71, and the two notches 73 correspond one-to-one with the two rotating gears 71, and the rotating gears 71 slide in contact with the inner sidewalls of the notches 73. An external gear ring 43 is disposed on the inner sidewall of the receiving groove 28 and is fixedly connected to the inner sidewall of the receiving groove 28. The axis of the external gear ring 43 coincides with the axis of the cooling box 2, and the external gear ring 43 meshes with the rotating gears 71.

[0055] When the drive gear 42 meshes with the external gear ring 43, the operator starts the drive motor 41. The drive motor 41 drives the cooling box 2 to rotate through the cooperation of the drive gear 42 and the external gear ring 43. The rotation of the cooling box 2 drives the reciprocating screw 61 and the rotating gear 71 to rotate around the axis of the cooling box 2. The cooperation of the rotating gear 71 with the internal gear ring 72 causes the rotating gear 71 to rotate. The rotation of the rotating gear 71 drives the reciprocating screw 61 to rotate, thereby driving the mounting ring 62 to move along the length of the reciprocating screw 61. The mounting ring 62 drives the scraper 63 to remove impurities in the cooling water.

[0056] Reference Figure 2A first rotating ring 24 is rotatably mounted on the bottom of the cooling tank 2, and a second rotating ring 25 is rotatably mounted on the top of the cooling tank 2. Two water outlets 26 are provided on the inner wall of the bottom of the cooling tank 2; one water outlet 26 is located in the first cooling zone 22, and the other water outlet 26 is located in the second cooling zone 23. The first rotating ring 24 is connected to the cooling tank 2 through the water outlets 26. Two water inlets 27 are provided on the inner wall of the top of the cooling tank 2; one water inlet 27 is located in the first cooling zone 22, and the other water inlet 27 is located in the second cooling zone 23. The second rotating ring 25 is connected to the cooling tank 2 through the water inlets 27.

[0057] Reference Figure 2 A water pump 8 is mounted on the base 1. An inlet pipe 81 is connected to the inlet of the water pump 8, and the end of the inlet pipe 81 furthest from the water pump 8 is connected to the first rotating ring 24. An outlet pipe 82 is connected to the outlet of the water pump 8, and the end of the outlet pipe 82 furthest from the water pump 8 is connected to the second rotating ring 25, with the opening of the outlet pipe 82 facing the copper wire 9. The water pump 8 is configured to ensure that cool water at a consistently low temperature impacts the copper wire 9, thereby rapidly cooling the heated copper wire 9.

[0058] The implementation principle of the production device for self-lubricating 200-grade polyamide-imide composite enameled copper round wire in this application embodiment is as follows: The operator uses the lifting component 3 to move the heated copper wire 9 to the first cooling zone 22. The cooling water in the first cooling zone 22 can continuously cool the heated copper wire 9. When the operator finds that there are many impurities in the cooling water in the first cooling zone 22, the operator first uses the lifting component 3 to move the heated copper wire 9 out of the cooling box 2. Then, the operator starts the rotating component 4. The operator uses the rotating component 4 to change the position of the first cooling zone 22 and the second cooling zone 23. Then, the operator uses the lifting component 3 to move the heated copper wire 9 to the cooling water in the second cooling zone 23, thereby ensuring the production efficiency of the copper wire 9. At the same time, the operator uses the cleaning component 6 to clean the impurities in the first cooling zone 22, thereby ensuring that there are no impurities in the cooling water in the first cooling zone 22 when the first cooling zone 22 and the second cooling zone 23 are exchanged next time.

[0059] This application discloses self-lubricating 200-grade polyamide-imide composite enameled copper round wire. (Refer to...) Figure 6 The self-lubricating 200-grade polyamide-imide composite enameled copper round wire includes a copper conductor 91 and a protective layer 92.
