Description

Technical Field

[0001] This invention belongs to the field of enameled wire production coating, specifically relating to a coating device for cable enameled wire production. Background Technology

[0002] In the production of enameled cable wires, the coating equipment is the core process equipment. Its task is to apply liquid insulating varnish evenly, continuously, and without bubbles to the surface of bare copper wires running at high speed, and to lay the foundation for subsequent baking and curing.

[0003] Patent CN220456166U discloses an energy-saving and environmentally friendly enameled wire production coating device, including a base plate, a coating mechanism installed at the front end of the base plate, a thermosetting mechanism installed at the rear end of the base plate with the same height as the coating mechanism, and an enameled wire passing through the coating mechanism and the thermosetting mechanism in sequence. The coating mechanism includes a shell with an internal hollow structure, an oil storage chamber located at the lower end of the shell, a coating chamber located at the upper end of the shell, a lower coating wheel installed at the lower end of the coating chamber and partially extending into the oil storage chamber for immersion, and an upper coating wheel installed at the upper end of the coating chamber with the same structure as the lower coating wheel. This patent uses the lower coating wheel and the upper coating wheel to coat the enameled wire, which can reduce the use of oil, and uses the thermosetting mechanism to heat and cure the coated enameled wire, avoiding oil flow and pollution of the workshop environment.

[0004] The above-mentioned device also has the following problems: uneven coating is easy to occur when coating the enameled wire by coating wheel. Therefore, the existing technology generally immerses the enameled wire in insulating varnish to ensure that it is fully coated. However, this can easily lead to the rapid consumption of insulating varnish in the container. If the insulating varnish is not replenished in time, the level of the insulating varnish will be below the top of the enameled wire, resulting in incomplete coating of the enameled wire and thus affecting its production quality. Summary of the Invention

[0005] The purpose of this invention is to provide a coating device for producing enameled wire of cables, which solves the problem that while the enameled wire is immersed in insulating varnish for full coating, this method can easily lead to rapid consumption of insulating varnish in the container. If the insulating varnish is not replenished in time, the level of the insulating varnish will be below the top of the enameled wire, resulting in incomplete coating of the enameled wire and thus affecting its production quality.

[0006] To achieve the above objectives, the present invention provides a coating apparatus for producing enameled wire of cables, comprising: a machine body, the machine body being composed of a box and a top cover; two guide rollers, a left pressure roller, a right pressure roller, and a support roller being rotatably connected inside the machine body; a partition plate being fixedly connected to the middle of the inner wall of the machine body, the partition plate dividing the interior of the machine body into a left chamber and a right chamber; the left pressure roller and the right pressure roller being located in the left chamber of the machine body; a flow guiding mechanism being provided in the left chamber of the machine body; a collection mechanism and a drying mechanism being provided in the right chamber of the machine body, with the drying mechanism located to the right of the collection mechanism; the support roller being rotatably connected to the inner wall of the top of the partition plate; the two guide rollers being rotatably connected to the inlet and outlet on both sides of the machine body; and insulating varnish being provided in the left chamber of the machine body. Multiple copper wires are guided into the device by guide rollers, left pressure rollers, right pressure rollers, and support rollers. The copper wires are immersed in the insulating varnish on the left side of the partition and coated. The coated copper wires are moved to the right side of the partition for drying, and then removed from the device and entered the subsequent device for multiple coatings. The left and right pressure rollers guide the copper wires downwards, so that the copper wires are immersed deep into the insulating varnish. Even if the insulating varnish is consumed, the copper wires can remain below the liquid surface of the insulating varnish most of the time. The flow guiding mechanism includes two guide plates, which are symmetrically fixed to the bottom of the left chamber of the machine body. A gear set is provided at the bottom of the machine body, and a motor is installed at the bottom of the gear set. The motor drives the internal gears of the gear set to rotate. Multiple spiral blades are connected to the top of the gear set. The gear set drives the multiple spiral blades to rotate synchronously and push the insulating varnish up. An external motor is started and drives the gear set to operate. The gear set drives the multiple spiral blades to rotate. When the spiral blades rotate, they push the insulating varnish upward. Even when the level of the insulating varnish is below the copper wire, the copper wire can still be completely immersed in the insulating varnish by the upward flow of the insulating varnish, thereby maintaining its coating quality. At the same time, it extends the interval between adding insulating varnish and improves work efficiency.

[0007] According to another advantageous design of the invention, the flow guiding mechanism further includes a guide post installed at the bottom of the left chamber wall of the machine body. A flexible tube is fixedly connected to the top of the guide post, and a movable rod is fixedly connected to the circumferential surface of the flexible tube. Two nozzles are fixedly connected to the end of the flexible tube away from the guide post. A cam is fixedly connected to the shaft center of the right pressure roller. The insulating varnish propelled by the spiral blades enters the guide post and is discharged through the rectangular holes on the front and rear sides of the guide post, falling onto the copper wire for coating. The remaining insulating varnish enters the flexible tube and is sprayed out through the two nozzles. The sprayed insulating varnish contacts the surface of the copper wire that has been removed from the liquid surface, thereby coating it a second time and preventing gaps in the contact part between the copper wire and the right pressure roller, which would affect the integrity of the coating.

[0008] According to another advantageous design of the invention, the circumferential surface of the cam contacts the circumferential surface of the moving rod, the circumferential surface of the moving rod is slidably connected to the inner wall of the machine body, a through groove is provided at the bottom of the guide post for insulating varnish to enter the guide post, and a rectangular groove is provided on the circumferential surface of the guide post for insulating varnish to be discharged and fall onto the copper wire surface. When the right pressure roller rotates, it drives the cam to rotate. The cam pushes the moving rod upward through the protrusion. When the cam protrusion passes the moving rod, the moving rod moves downward again by its own weight. This reciprocating motion realizes the reciprocating up and down movement of the moving rod. The moving rod drives the hose and the nozzle on its surface to move together, thereby increasing the spraying range of the nozzle and improving the effect of secondary coating.

[0009] According to another advantageous design of the invention, the collection mechanism includes a collection box installed in the right chamber of the machine body. A lower scraper is installed on the inner wall of the collection box. A lower rubber roller and an upper rubber roller are rotatably connected to the right chamber of the machine body. A fixing plate is fixedly connected to the right chamber of the machine body. An upper scraper is fixedly connected to the bottom of the fixing plate. The coated copper wire enters between the lower and upper rubber rollers, but the copper wire does not contact the lower and upper rubber rollers. The distance between them increases sequentially according to the number of coatings, ensuring that the lower and upper rubber rollers only adhere and remove excess insulating varnish from the copper wire, preventing excessive insulating varnish from forming droplets at the bottom of the copper wire, which could lead to excessive wire diameter and substandard quality during subsequent curing.

[0010] According to another advantageous design of the invention, the upper rubber roller is located above the lower rubber roller, the top of the lower scraper is in contact with the circumferential surface of the lower rubber roller, the left side of the upper scraper is in contact with the circumferential surface of the upper rubber roller, and the upper scraper is inclined to the lower right.

[0011] According to another advantageous design of the present invention, the collection mechanism further includes a movable frame slidably connected to the bottom of the upper scraper. A connecting plate is fixedly connected to the right side of the movable frame. A guide groove is formed on the inner wall of the connecting plate. A guide groove is formed at the bottom of the upper scraper. The left side of the connecting plate contacts the right side of the upper scraper. The lower scraper can scrape off excess insulating varnish from the surface of the lower rubber roller and collect it in the collection box. At the same time, the upper scraper can scrape off the insulating varnish from the upper rubber roller and guide it through the guide groove on its own surface. This allows the insulating varnish to flow in the guide groove that slopes downward to the right and into the guide groove on the connecting plate. Finally, it flows downward through the guide groove, passes between the two copper wires, and drips into the collection box, facilitating the recycling and reuse of the insulating varnish. The movable frame at the bottom of the upper scraper can prevent the insulating varnish from dripping from the guide groove. Even if it drips, it can be guided into the guide groove on the connecting plate by the movable frame.

[0012] According to another advantageous design of the present invention, the drying mechanism includes a mounting block fixedly connected to the right chamber of the machine body. Multiple rotating cylinders are rotatably connected to the inner wall of the mounting block. An air inlet pipe is fixedly connected to the top of the mounting block. Several teeth are fixedly connected to the circumferential surface of the rotating cylinders. An air chamber is formed inside the mounting block. An annular groove is formed on the circumferential surface of the rotating cylinders. An air outlet plate is installed on the inner wall of the rotating cylinders. After excess insulating varnish falls off, the copper wire enters the rotating cylinder. At this time, hot air is introduced into the air inlet pipe by an external fan. The hot air enters the air chamber and then enters the annular grooves on the multiple rotating cylinders, and then enters the air outlet plate through the annular grooves. The hot air is blown obliquely onto the surface of the copper wire through the air outlet plate, causing the insulating varnish on the surface of the copper wire to dry quickly.

[0013] According to another advantageous design of the invention, the air outlet plate is connected to the annular groove, the annular groove is connected to the air chamber, the air chamber is connected to the air inlet pipe, a motor is mounted on the mounting block, the motor drives the rotating drum to rotate through gears and teeth, the teeth of the plurality of rotating drum circumferential surfaces mesh with each other in sequence, and the mounting block is located on the right side of the upper rubber roller.

[0014] According to another advantageous design of the invention, the drying mechanism further includes an inclined plate, which is fixedly connected to the left side of the rotating drum. A transmission rod is slidably connected to the inner wall of the left side of the mounting block. A roller is rotatably connected to the right end of the transmission rod, and the roller contacts the left side of the rotating drum. The roller is located on the movement trajectory of the inclined plate. The left end of the transmission rod is fixedly connected to the right side of the connecting plate. An external motor drives the rotating drum at one end to rotate. The rotating drum drives the remaining rotating drum to rotate synchronously through teeth. The rotating drum drives the air outlet plate to rotate, so that the air outlet plate can blow hot air while rotating, improving the uniformity of drying the insulating varnish on the copper wire. At the same time, when the rotating drum rotates, it drives the inclined plate to rotate. The inclined plate pushes the transmission rod to move through the inclined surface. When the inclined plate passes the transmission rod, the transmission rod self-realigns. The transmission rod drives the connecting plate to move back and forth. The connecting plate drives the moving frame to move back and forth. The reciprocating movement of the moving frame and the connecting plate can promote the rapid sliding of the dripping insulating varnish, reducing the residue of the drying insulating varnish on its surface.

[0015] The beneficial effects of this invention are: 1. The left and right pressure rollers guide the copper wire downwards, allowing it to penetrate deep into the insulating varnish. Even as the varnish is consumed, the copper wire remains below the varnish surface most of the time. Simultaneously, the rotating spiral blades push the varnish upwards, ensuring that even when the varnish surface is below the copper wire, the upward flow of the varnish keeps the wire fully submerged, maintaining coating quality and extending the varnish replenishment interval, thus improving work efficiency. The varnish propelled by the spiral blades enters the guide column and then the hose, being sprayed out through two nozzles. The sprayed varnish contacts the surface of the copper wire that has emerged from the varnish, providing a secondary coating and preventing gaps between the copper wire and the right pressure roller, which could affect the integrity of the coating. The moving rod moves the hose and the nozzles on its surface together, increasing the spraying range and improving the effect of the secondary coating.

[0016] 2. The lower and upper rubber rollers will adhere to and carry away excess insulating varnish on the copper wire, preventing excessive varnish from forming droplets at the bottom of the copper wire, which could lead to excessive wire diameter and substandard quality during subsequent curing. At the same time, the lower scraper can scrape off excess insulating varnish from the surface of the lower rubber roller and collect it in the collection box. The upper scraper can scrape off the insulating varnish from the upper rubber roller, which flows downward through the guide groove, passes between the two copper wires, and drips into the collection box, facilitating the recycling and reuse of the insulating varnish. The movable frame at the bottom of the upper scraper can prevent the insulating varnish from dripping into the guide groove. Even if it drips, it can be guided into the guide groove on the connecting plate by the movable frame.

[0017] 3. After excess insulating varnish falls off, the copper wire will enter the rotating drum. At this time, hot air is introduced into the air inlet pipe by an external fan. The hot air is blown onto the surface of the copper wire through the inclined air outlet plate, which promotes the rapid drying of the insulating varnish on the surface of the copper wire. At the same time, multiple rotating drums rotate, so that the air outlet plate can blow hot air while rotating, which improves the uniformity of drying of the insulating varnish on the copper wire. Furthermore, through the rotation of the rotating drum and the transmission of the inclined plate and the transmission rod, the connecting plate drives the moving frame to move back and forth. The back and forth movement of the moving frame and the connecting plate can promote the rapid sliding off of the dripping insulating varnish, reducing the residue of the insulating varnish on its surface after drying.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1-10 As shown, one embodiment of the present invention is a coating apparatus for producing enameled wire of cables, comprising: a body 1, which is composed of a housing and a top cover, characterized in that two guide rollers 2, a left pressure roller 21, a right pressure roller 22, and a support roller 23 are rotatably connected inside the body 1, and a partition 4 is fixedly connected to the middle of the inner wall of the body 1, dividing the interior of the body 1 into a left chamber and a right chamber, with the left pressure roller 21 and the right pressure roller 22 located in the left chamber of the body 1, and a flow guide provided in the left chamber of the body 1. Mechanism 3, the right chamber of the machine body 1 is respectively equipped with a collection mechanism 5 and a drying mechanism 6, and the drying mechanism 6 is located to the right of the collection mechanism 5. The support roller 23 is rotatably connected to the inner wall of the top of the partition 4. The two guide rollers 2 are rotatably connected to the inlet and outlet on both sides of the machine body 1. The left chamber of the machine body 1 is equipped with insulating varnish. The left pressure roller 21 and the right pressure roller 22 will guide the copper wire downward, so that the copper wire is immersed in the depth of the insulating varnish. Even if the insulating varnish is consumed, the copper wire can still remain below the liquid surface of the insulating varnish most of the time. The flow guiding mechanism 3 includes two guide plates 31, which are symmetrically fixed to the bottom of the left chamber wall of the machine body 1. A gear set 32 ​​is provided at the bottom of the machine body 1, and a motor is installed at the bottom of the gear set 32. The motor is used to drive the internal gears of the gear set 32 ​​to rotate. Multiple spiral blades 33 are connected to the top of the gear set 32. The gear set 32 ​​is used to drive the multiple spiral blades 33 to rotate synchronously and surge the insulating varnish. When the spiral blades 33 rotate, they will push the insulating varnish upward. Even when the level of the insulating varnish is below the copper wire, the copper wire can still be completely immersed in the insulating varnish by the surge of the insulating varnish, thereby maintaining its coating quality, while extending the interval of adding insulating varnish and improving work efficiency.

[0022] The flow guiding mechanism 3 also includes a guide post 34, which is installed at the bottom of the left chamber wall of the machine body 1. A hose 35 is fixedly connected to the top of the guide post 34, and a moving rod 36 is fixedly connected to the circumferential surface of the hose 35. Two nozzles are fixedly connected to the end of the hose 35 away from the guide post 34. A cam 37 is fixedly connected to the shaft of the right pressure roller 22. The insulating varnish propelled by the spiral blade 33 enters the guide post 34 and the hose 35, and is sprayed out through the two nozzles. The sprayed insulating varnish contacts the surface of the copper wire that has been removed from the liquid surface, and then coats it a second time to prevent gaps in the contact part between the copper wire and the right pressure roller 22, which would affect the integrity of the coating. The moving rod 36 drives the hose 35 and the nozzles on its surface to move together, thereby increasing the spraying range of the nozzles and improving the effect of the second coating.

[0023] The circumferential surface of the cam 37 contacts the circumferential surface of the moving rod 36, and the circumferential surface of the moving rod 36 is slidably connected to the inner wall of the body 1. A through groove is provided at the bottom of the guide post 34 for insulating varnish to enter the guide post 34. A rectangular groove is provided on the circumferential surface of the guide post 34 for insulating varnish to be discharged and fall onto the surface of the copper wire.

[0024] Working principle: The top cover is opened, and multiple copper wires are guided into the device via guide roller 2, left pressure roller 21, right pressure roller 22, and support roller 23. The copper wires are immersed in the insulating varnish on the left side of the partition 4 for coating. After coating, the copper wires move to the right side of the partition 4 for drying, then are removed from the device and enter subsequent processes for multiple coatings. The left and right pressure rollers 21 and 22 guide the copper wires downwards, allowing them to penetrate deep into the insulating varnish. Even as the insulating varnish is consumed, the copper wires remain below the varnish surface most of the time. Simultaneously, an external motor starts and drives the gear set 32, which in turn rotates multiple spiral blades 33. The rotation of the spiral blades pushes the insulating varnish upwards. Even when the varnish surface is below the copper wires, the upward flow of the varnish ensures that the copper wires are fully immersed, thus maintaining the coating quality. Meanwhile, the interval between adding insulating varnish is extended, improving work efficiency. The insulating varnish propelled by the spiral blade 33 enters the guide column 34 and is discharged through the rectangular holes on both sides of the guide column 34, landing on the copper wire for coating. The remaining insulating varnish enters the hose 35 and is sprayed out through two nozzles. The sprayed insulating varnish contacts the surface of the copper wire that has been removed from the liquid surface, thus coating it a second time. This prevents gaps in the contact area between the copper wire and the right pressure roller 22, which would affect the integrity of the coating. When the right pressure roller 22 rotates, it drives the cam 37 to rotate. The cam 37 pushes the moving rod 36 upward through its protrusion. When the protrusion of the cam 37 passes the moving rod 36, the moving rod 36 moves downward again due to its own weight. This reciprocating motion of the moving rod 36 achieves the up-and-down movement of the moving rod 36. The moving rod 36 drives the hose 35 and the nozzles on its surface to move together, thereby increasing the spraying range of the nozzles and improving the effect of the second coating.

[0025] like Figure 1-10 As shown, based on the above embodiment, the collection mechanism 5 includes a collection box 51, which is installed in the right chamber of the machine body 1. A lower scraper 52 is installed on the inner wall of the collection box 51. A lower rubber roller 53 and an upper rubber roller 54 are rotatably connected to the right chamber of the machine body 1. A fixing plate 55 is fixedly connected to the right chamber of the machine body 1. An upper scraper 56 is fixedly connected to the bottom of the fixing plate 55. The lower rubber roller 53 and the upper rubber roller 54 will adhere and carry away excess insulating varnish on the copper wire, preventing excessive insulating varnish from forming droplets at the bottom of the copper wire, which would lead to excessive wire diameter and substandard quality during subsequent curing.

[0026] The upper rubber roller 54 is located above the lower rubber roller 53. The top of the lower scraper 52 contacts the circumferential surface of the lower rubber roller 53, and the left side of the upper scraper 56 contacts the circumferential surface of the upper rubber roller 54. The upper scraper 56 is inclined to the lower right. The lower scraper 52 can scrape off the excess insulating varnish on the surface of the lower rubber roller 53 and collect it in the collection box 51. The upper scraper 56 can scrape off the insulating varnish on the upper rubber roller 54 and let it flow downward through the guide groove 59, pass between the two copper wires, and drip into the collection box 51, which facilitates the recycling and reuse of the insulating varnish.

[0027] The collection mechanism 5 also includes a movable frame 57, which is slidably connected to the bottom of the upper scraper 56. A connecting plate 58 is fixedly connected to the right side of the movable frame 57. A guide groove 59 is provided on the inner wall of the connecting plate 58. A guide groove 510 is provided at the bottom of the upper scraper 56. The left side of the connecting plate 58 is in contact with the right side of the upper scraper 56.

[0028] The air drying mechanism 6 includes a mounting block 61, which is fixedly connected to the right chamber of the body 1. Multiple rotating cylinders 63 are rotatably connected to the inner wall of the mounting block 61. An air inlet pipe 62 is fixedly connected to the top of the mounting block 61. Several teeth 64 are fixedly connected to the circumferential surface of the rotating cylinders 63. An air chamber 67 is opened inside the mounting block 61. An annular groove 68 is opened on the circumferential surface of the rotating cylinders 63. An air outlet plate 69 is installed on the inner wall of the rotating cylinders 63. After excess insulating varnish falls off, the copper wire will enter the rotating cylinders 63. At this time, hot air is introduced into the air inlet pipe 62 by an external fan. The hot air is blown obliquely to the surface of the copper wire through the air outlet plate 69, which promotes the rapid drying of the insulating varnish on the surface of the copper wire.

[0029] The air outlet plate 69 is connected to the annular groove 68, the annular groove 68 is connected to the air chamber 67, the air chamber 67 is connected to the air inlet pipe 62, and a motor is installed on the mounting block 61. The motor drives the rotating drum 63 to rotate through gears and teeth 64. The teeth 64 on the circumference of multiple rotating drums 63 mesh with each other in sequence. The mounting block 61 is located on the right side of the upper rubber roller 54.

[0030] The drying mechanism 6 also includes an inclined plate 65, which is fixedly connected to the left side of the rotating drum 63. A transmission rod 66 is slidably connected to the inner wall of the left side of the mounting block 61. A roller is rotatably connected to the right end of the transmission rod 66, and the roller is in contact with the left side of the rotating drum 63. The roller is located on the movement trajectory of the inclined plate 65. The left end of the transmission rod 66 is fixedly connected to the right side of the connecting plate 58. The rotation of multiple rotating drums 63 allows the air outlet plate 69 to rotate and blow hot air at the same time, improving the uniformity of drying the insulating varnish on the copper wire. Furthermore, through the rotation of the rotating drum and the transmission of the inclined plate 65 and the transmission rod 66, the connecting plate 58 drives the moving frame 57 to move back and forth. The reciprocating movement of the moving frame 57 and the connecting plate 58 can promote the rapid sliding of the dripping insulating varnish, reducing the residue of the insulating varnish drying on its surface.

[0031] Working principle: The coated copper wire enters between the lower rubber roller 53 and the upper rubber roller 54, but the copper wire does not contact the lower rubber roller 53 and the upper rubber roller 54. The distance between them increases with the number of coatings to ensure that the lower rubber roller 53 and the upper rubber roller 54 only adhere and remove excess insulating varnish from the copper wire. This prevents excessive insulating varnish from forming droplets at the bottom of the copper wire, which could lead to excessive wire diameter and substandard quality during subsequent curing. At the same time, the lower scraper 52 can scrape off excess insulating varnish from the surface of the lower rubber roller 53 and collect it in the collection box 51. Meanwhile, the upper scraper 56 can... The insulating varnish on the upper rubber roller 54 is scraped off and guided by the guide groove 510 on its surface. The insulating varnish flows in the guide groove 510 that slopes downward to the right and flows into the guide groove 59 on the connecting plate 58. Finally, it flows downward through the guide groove 59, passes between the two copper wires, and drips into the collection box 51, which facilitates the recycling and reuse of the insulating varnish. The movable frame 57 set at the bottom of the upper scraper 56 can prevent the insulating varnish from dripping in the guide groove 510. Even if it drips, it can enter the guide groove 59 on the connecting plate 58 under the guidance of the movable frame 57. After excess insulating varnish falls off, the copper wire enters the rotating drum 63. At this time, hot air is introduced into the air inlet pipe 62 by an external fan. The hot air enters the air chamber 67 and then enters the annular grooves 68 on multiple rotating drums 63. Through the annular grooves 68, the hot air enters the air outlet plate 69. The hot air is blown obliquely onto the surface of the copper wire through the air outlet plate 69, causing the insulating varnish on the surface of the copper wire to dry quickly. At the same time, an external motor drives one end of the rotating drum 63 to rotate. The rotating drum 63 drives the remaining rotating drums 63 to rotate synchronously through the teeth 64. The rotating drum 63 drives the output... The air plate 69 rotates, allowing it to blow hot air while rotating, improving the uniformity of drying the insulating varnish on the copper wire. At the same time, the rotating drum 63 drives the inclined plate 65 to rotate. The inclined plate 65 pushes the transmission rod 66 to move through the inclined surface. After the inclined plate 65 passes the transmission rod 66, the transmission rod 66 self-realigns. The transmission rod 66 drives the connecting plate 58 to move back and forth. The connecting plate 58 drives the moving frame 57 to move back and forth. The back and forth movement of the moving frame 57 and the connecting plate 58 can make the dripping insulating varnish slide off quickly, reducing the residue of the insulating varnish drying on its surface.
