Description

Technical Field

[0001] This invention relates to the field of enameled round wire technology, and more specifically, to an adjustable anti-scratch guide roller for the production of enameled round wire. Background Technology

[0002] Enamelled round wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer specifications is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enamelled round wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.

[0003] According to existing technology, in the continuous production process of enameled round wire, the guide roller is the core conveying and control component that runs through the entire process of unwinding, annealing, painting, baking, cooling and winding. After the paint mist and solvent evaporate at the painting station, they will solidify on the surface of the guide roller to form hard paint particles or paint scale. At the same time, dust and metal shavings will also adhere to the roller surface during production. Traditional cleaning mechanisms mostly use a single felt, a single scraper or a simple air blowing structure. When faced with complex working conditions such as solid paint residue and dust, the cleaning blind spots will result in insufficient cleaning effect on the surface of the guide roller. Summary of the Invention

[0004] This invention provides an adjustable anti-scratch guide roller for enameled round wire production. By incorporating a cleaning device using a motor-driven rotating rod in conjunction with a polyurethane hook-shaped scraper, a sponge sheet, and a snap-fit ​​felt brush, it replaces other cleaning methods such as solid impurity scraping, fine dust removal, and liquid waste adsorption. This solves the problem mentioned in the background art, namely, the insufficient cleaning effect on the guide roller surface due to the existence of cleaning blind spots when facing complex working conditions such as solid paint residue and dust.

[0005] To achieve the above objectives, an adjustable anti-scratch guide roller for enameled round wire production is provided, comprising a machine body and a cleaning device. A control box is fixedly installed on one side of the machine body. Two rollers are rotatably connected inside the machine body. The cleaning device includes a base plate located at the bottom of the rollers. A rotating rod is rotatably connected inside the base plate. A fixing plate is fixedly connected to the outside of the rotating rod. A scraper is fixedly installed inside the fixing plate by bolts. The scraper fits against the outer wall of the roller. A drive assembly is provided at the top of the machine body and the bottom of the base plate for adjusting the height of the base plate and the cleaning device.

[0006] In the above technical solution, the drive assembly includes two electric push rods fixedly connected to the top of the machine body. The output end of the electric push rod is fixedly connected to a top plate. The electric push rod is fixedly connected to the bottom of the base plate through the top plate. Two sleeves are fixedly connected to the top of the machine body. A sliding rod is fixedly connected to the bottom of the base plate near the sleeve. The outside of the sliding rod and the inside of the sleeve are slidably connected to guide and limit the lifting and lowering movement of the base plate.

[0007] Secondly, a storage plate is fixedly connected to the outer wall of the rotating rod. A sponge sheet is adhered to the inside of the storage plate to absorb residual cleaning agent during the cleaning of the roller. Excess cleaning agent is collected through adsorption. A placement plate is fixedly connected to the outer wall of the rotating rod. A retaining plate is snapped into the inside of the placement plate. A felt brush is fixedly connected to the end of the retaining plate away from the placement plate. The felt brush is used to flexibly clean the surface of the roller. The scraper is a polyurethane scraper, which is used to flexibly conform to the roller surface and scrape off and peel off solid impurities such as cured paint residue and dust adhering to the roller surface. A motor is fixedly installed inside the base plate. The output end of the motor is fixedly connected to one side of the rotating rod. A hook-shaped strip is fixedly connected to the top of the scraper to prevent impurities and waste liquid from splashing due to the centrifugal force generated by the high-speed rotation of the roller surface.

[0008] Furthermore, the side wall of the base plate is provided with an air blowing device, which includes multiple connecting rods fixedly connected to the side wall of the base plate. One end of each connecting rod near the roller is fixedly connected to an air pipe. An air guide plate is fixedly connected to the outer wall of the air pipe. The air guide plate is located on one side of the roller and is used to guide the gas in the air pipe to the surface of the roller. The end of the air pipe away from the machine body is fixedly connected to a connector for communicating with an external air source. An air baffle is fixedly connected to the outside of the air guide plate. The air baffle is in contact with the roller and is used to concentrate the airflow.

[0009] Based on the above, an air distribution device is provided on the outside of the trachea. The air distribution device includes an air distribution plate fixedly connected to the outer wall of the trachea. Fixed blocks are fixedly connected to both sides of the air distribution plate. Moving rods are slidably connected inside the fixed blocks. Baffles are fixedly connected to the tops of the two moving rods. Threaded columns are threadedly connected inside the fixed blocks. The threaded columns fit with the moving rods. Limiting blocks are fixedly connected to the bottom of the moving rods. The limiting blocks are located directly below the fixed blocks.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: This adjustable anti-scratch guide roller for enameled round wire production uses an electric push rod and sliding sleeve for guidance, which allows for stepless adjustment of the cleaning device height and control of contact pressure. It is suitable for rollers of different specifications and enameled round wires. The cleaning device is driven by a motor to rotate the rotating rod actively, matching the roller's linear speed to achieve synchronous cleaning with the roller and avoid relative slippage. Combined with a polyurethane flexible scraper, it effectively removes cured paint residue and hard particles without damaging the mirror-like roller surface. The hook-shaped strip at the top of the scraper prevents impurities and waste liquid from splashing due to centrifugal force. The sponge sheet inside the collection plate absorbs and collects the cleaning agent to control the liquid and prevent dripping. The snap-fit ​​felt brush completes flexible fine cleaning and can be quickly replaced. The multi-stage synergy creates a cleaning effect that removes solid impurities, cleans fine dust, and absorbs liquid waste liquid. The air blowing device achieves directional airflow blowing through the air guide plate, and the universal connector can be quickly adapted to external air sources. The air distribution device controls the width and intensity of the airflow through the adjustable baffle plate and threaded locking structure to adapt to different roller widths and cleaning needs. Through mechanical scraping, flexible fine cleaning, waste liquid absorption, and airflow blowing, the guide roller and enameled round wire are cleaned, thereby preventing residual impurities from scratching the enameled round wire.

[0013] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0014] When faced with complex working conditions involving solid paint residue and dust, insufficient cleaning of the guide roller surface may occur due to the existence of cleaning blind spots.

[0015] Therefore, in view of the above-mentioned problems, the present invention provides an adjustable anti-scratch guide roller for enameled round wire production, with reference to... Figures 1-4 As shown, the device includes a machine body 1 and a cleaning device 4. A control box 2 is fixedly installed on one side of the machine body 1. Two rollers 3 are rotatably connected inside the machine body 1. The cleaning device 4 includes a base plate 401 located at the bottom of the rollers 3. A rotating rod 402 is rotatably connected inside the base plate 401. The rotating rod 402 can flexibly adjust the position of each component, so that the components with different cleaning functions can adjust the contact time with the rollers 3 according to the needs. A fixing plate 403 is fixedly connected to the outside of the rotating rod 402. A scraper 404 is fixedly installed inside the fixing plate 403 by bolts. The bolt fixing method facilitates the disassembly, replacement and maintenance of the scraper 404, reducing maintenance costs. The scraper 404 is in contact with the outer wall of the roller 3 to scrape off the solidified paint residue, dust and other impurities attached to the roller surface, avoiding the impurities remaining and crushing the enameled round wire, which would cause scratches. A storage plate 405 is fixedly connected to the outer wall of the rotating rod 402. The storage plate 405 provides an installation carrier for the sponge sheet 406, ensuring that the sponge sheet 406 fits tightly and is not easy to fall off. The sponge sheet 406 is bonded to the inside of the storage plate 405 to absorb the cleaning agent remaining during the cleaning of the roller body 3. Excess cleaning agent is collected through adsorption, reducing the situation of residual waste liquid on the roller surface, while ensuring that the roller surface is dry and clean. A placement plate 408 is fixedly connected to the outer wall of the rotating rod 402. A clamping plate 409 is snapped into the inside of the placement plate 408. A felt brush 410 is fixedly connected to the end of the clamping plate 409 away from the placement plate 408. The felt brush 410 is used to perform flexible cleaning on the surface of the roller body 3. It can remove the fine dust remaining on the scraper 404, and the flexible contact will not scratch the mirror surface of the roller body 3, achieving secondary fine cleaning and further improving the cleanliness of the roller surface. The scraper blade 404 is a polyurethane scraper blade 404, which is used to flexibly bond the roller body 3 roller surface, scrape off and peel off solid impurities such as cured paint residue and dust attached to the roller surface. The motor 407 is fixedly installed inside the base plate 401. The output end of the motor 407 is fixedly connected to one side of the rotating rod 402. The top of the scraper blade 404 is fixedly connected to a hook-shaped strip 411, which is used to prevent impurities and waste liquid after scraping from splashing due to the centrifugal force generated by the high speed rotation of the roller surface, effectively avoiding impurities and waste liquid from rebounding back to the roller surface and causing secondary pollution.

[0016] refer to Figure 3 As shown, the top of the machine body 1 and the bottom of the base plate 401 are provided with a drive assembly 5, which is used to realize the overall height adjustment of the base plate 401 and the cleaning device 4, adapt to rollers 3 of different diameters, and also facilitate the adjustment of the position of scraper 404, sponge 406 and felt brush 410. The drive assembly 5 includes two electric push rods 51 fixedly connected to the top of the machine body 1. The electric push rods 51 provide a balanced and stable lifting drive force. The output end of the electric push rod 51 is fixedly connected to the top plate 52. The electric push rod 51 is fixedly connected to the bottom of the base plate 401 through the top plate 52. The top plate 52 increases the contact area between the electric push rod 51 and the base plate 401, making the thrust transmission more uniform and reliable, and effectively preventing local stress concentration from causing deformation of the base plate 401. Two sleeves 53 are fixedly connected to the top of the body 1. The sleeves 53 provide stable sliding guidance for the slide rod 54. A slide rod 54 is fixedly connected to the bottom of the base plate 401 near the sleeve 53. The slide rod 54 is slidably connected to the outside of the sleeve 53. It is used to guide and limit the lifting and lowering movement of the base plate 401, constrain the lifting and lowering trajectory of the base plate 401, and prevent lateral deviation, shaking or tilting during the lifting and lowering process.

[0017] refer to Figure 5 and Figure 6 As shown, the side wall of the base plate 401 is provided with an air blowing device 6, which works in conjunction with the mechanical cleaning components to achieve dual cleaning of mechanical scraping and airflow blowing. The air blowing device 6 includes multiple connecting rods 61 that are fixedly connected to the side wall of the base plate 401. The multiple connecting rods 61 are evenly distributed to provide stable and balanced support for the air pipe 62. Multiple connecting rods 61 are fixedly connected to one end of the roller body 3 with an air pipe 62. An air guide plate 64 is fixedly connected to the outer wall of the air pipe 62. The air guide plate 64 is located on one side of the roller body 3 and is used to guide the gas in the air pipe 62 to the surface of the roller body 3 to achieve directional and concentrated airflow. A connector 63 is fixedly connected to the end of the air pipe 62 away from the machine body 1 for connecting with an external air source. An air baffle plate 65 is fixedly connected to the outside of the air guide plate 64. The air baffle plate 65 is in contact with the roller body 3 and is used to gather the airflow.

[0018] refer to Figure 6 As shown, an air distribution device 7 is provided on the outside of the air pipe 62. The air distribution device 7 includes an air distribution plate 71 fixedly connected to the outer wall of the air pipe 62. The air distribution plate 71 improves the airflow utilization efficiency and uses the same air source to clean the roller body 3 and the enameled round wire respectively. Fixed blocks 72 are fixedly connected to both sides of the air distribution plate 71. A moving rod 73 is slidably connected inside the fixed block 72. The moving rod 73 can be conveniently adjusted to adjust the height of subsequent components, thereby adapting to enameled round wires of different specifications. The tops of the two moving rods 73 are fixedly connected to baffles 74, which can block the airflow and allow the airflow to flow downward from the top of the enameled round wire, thereby wrapping and cleaning the enameled round wire. The fixed block 72 has a threaded post 75 inside, which fits with the moving rod 73. Tightening the threaded post 75 can tighten and lock the moving rod 73. The bottom of the moving rod 73 is fixedly connected to a limit block 76, which is located directly below the fixed block 72. The limit block 76 effectively restricts the downward sliding stroke of the moving rod 73 and prevents the moving rod 73 from slipping out of the fixed block 72.

[0019] Working principle of the invention: The two electric push rods 51 at the top of the machine body 1 are activated. The electric push rods 51 transmit thrust to the bottom plate 401 through the top plate 52, which drives the bottom plate 401 to rise and fall. The slide rod 54 at the bottom of the bottom plate 401 slides in the sleeve 53, adjusting the scraper 404, sponge 406 and felt brush 410 to the height of contact with the outer wall of the roller body 3. At the same time, the contact pressure between each cleaning component and the roller surface is adjusted as needed.

[0020] For enameled round wires of different specifications, loosen the threaded post 75 on the fixing block 72, slide the moving rod 73 up and down, and adjust the height of the baffle plate 74 to match the position of the enameled round wire; after adjustment, tighten the threaded post 75 so that the threaded post 75 presses against the moving rod 73 to lock it in place, and the limit block 76 restricts the stroke of the moving rod 73 to ensure the airflow has a wrapping cleaning effect on the enameled round wire.

[0021] The motor 407 inside the base plate 401 starts, driving the rotating rod 402 to rotate at a constant speed. The rotating rod 402 drives the external fixing plate 403, storage plate 405, and placement plate 408 to rotate synchronously, so that the scraper 404, sponge sheet 406, and felt brush 410 are attached to the surface of the roller body 3 in sequence according to the process. The rotating rod 402 drives the fixing plate 403 to rotate, so that the scraper 404 flexibly attaches to the roller body 3, scraping off and peeling off the solid impurities such as cured paint residue and dust attached to the roller surface. The hook-shaped strip 411 at the top of the scraper 404 works synchronously to prevent the scraped impurities and cleaning waste liquid from splashing outward due to the centrifugal force generated by the high-speed rotation of the roller body 3.

[0022] After the scraper blade 404 completes the coarse scraping, the rotating rod 402 continues to rotate, causing the felt brush 410 on the placement plate 408 to come into contact with the roller surface. The felt brush 410 performs a secondary cleaning of the roller body 3 in a flexible contact manner, removing the fine dust that the scraper blade 404 did not remove. The flexible material will not scratch the mirror surface of the roller body 3, further improving the cleanliness of the roller surface and avoiding the residue of fine impurities.

[0023] If the roller body 3 is cleaned with the aid of a cleaning agent, the rotating rod 402 drives the sponge sheet 406 on the storage plate 405 to adhere to the roller surface. The sponge sheet 406 absorbs the cleaning agent remaining on the roller surface after cleaning through adsorption, reducing the waste liquid residue on the roller surface. At the same time, it quickly dries the roller surface, ensuring that the roller body 3 is always in a dry and clean state, and preventing waste liquid from mixing with impurities and adhering to the roller surface.

[0024] The air distribution device 7 outside the air pipe 62 realizes the air source diversion. While cleaning the roller body 3, it simultaneously cleans the enameled round wire in the conveyor. The airflow in the air pipe 62 is diverted by the air distribution plate 71. Part of the airflow is used to blow the roller body 3, and the other part of the airflow is conveyed upward to the position of the baffle plate 74. The air guide plate 64 guides the airflow to the roller body 3, the baffle plate 65 blocks the airflow, while the air distribution plate 71 guides the airflow to the enameled round wire, and the baffle plate 74 blocks the airflow from going up, so that the airflow flows downward from the top of the enameled round wire, forming an enveloping airflow, which blows the surface of the enameled round wire and removes the dust and paint residue attached to the enameled round wire itself.

[0025] During production, the rotating rod flexibly adjusts the position of each cleaning component, switching the working state of the scraper, felt brush, and sponge as needed to adapt to different cleaning requirements; the scraper is fixed with bolts, and can be quickly disassembled, replaced, and repaired during production breaks.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
