Description

Technical Field

[0001] This utility model relates to the field of enameled wire processing technology, specifically to a painting device for processing flat enameled wires. Background Technology

[0002] Flat enameled wire is a special type of wire with a rectangular or trapezoidal cross-section. It is commonly used in transformers, motors, and other electrical equipment that requires efficient space utilization. Enameling is one of the key steps in the manufacture of enameled wire. Through this process, one or more layers of insulating varnish are formed on the surface of the conductor to ensure electrical performance and mechanical protection.

[0003] Existing coating devices for flat enameled wire processing can be referenced from Chinese Utility Model Patent Publication No. CN221529581U, which discloses a coating structure for self-adhesive direct-welding polyurethane enameled wire. This structure includes a wire frame, a heater, and a coating box. The wire frame has two top wire rollers, two bottom wire rollers, and a coating wire roller located between the two bottom wire rollers. The two top wire rollers and the two bottom wire rollers are on the same horizontal plane. The coating wire roller is located below the horizontal plane of the bottom wire rollers. The same number of wire wheels are rotatably connected to the top, bottom, and coating wire rollers. The coating box is located below the coating wire roller, and the wire wheel portion of the coating wire roller is located inside the coating box. The heater is located between the two top wire rollers. This utility model has advantages such as small space occupation.

[0004] The above-mentioned device has good performance, but there are still some defects in its actual use. The device coats the enameled wire with paint by using a paint roller. However, the distance between the paint roller and the paint box is fixed, which makes it inconvenient to adjust the distance between the paint roller and the paint box according to different usage requirements. Different specifications of flat enameled wire may require different paint thicknesses or immersion depths. The fixed distance limits the device's adaptability to various specifications of products and reduces the equipment's versatility and flexibility. Utility Model Content

A lifting threaded block is threadedly connected to the surface of the lifting threaded rod. The lifting threaded block is slidably connected to the guide rod. The tops of the two lifting threaded rods extend to the front and rear sides of the interior of the rectangular shell and are rotatably connected to them.

[0012] In a preferred embodiment of this invention, the lifting threaded rod is provided with worm gears fixedly mounted on the inner surface of the rectangular shell, and the two worm gears are meshed with the same worm on one side. A second motor is fixedly connected to one side of the inner wall of the rectangular shell, and the output shaft of the second motor is fixedly connected to one end of the worm.

[0013] As a preferred embodiment of this utility model, a controller is fixedly connected to the front surface of the paint box, and a first rotating shaft and a second rotating shaft are fixedly connected to the inner walls of the pay-off roller and the take-up roller, respectively.

[0027] Example 1

[0028] Reference Figure 1-3 The first embodiment of this utility model provides a coating device for processing flat enameled wire, including a base 1 and a take-up roller 4 and a pay-off roller 3 respectively disposed on the left and right sides of its top:

[0029] Furthermore, the base 1 is equipped with a painting mechanism at its top. The painting mechanism includes a paint box 2 fixedly installed at the center of the top of the base 1. Multiple mounting slots 11 are equidistantly arranged on both the left and right sides of the top of the paint box 2. Wire guide rollers 12 are rotatably connected inside the multiple mounting slots 11. A U-shaped frame 13 is fixedly connected at the center of the top of the paint box 2. The front and rear ends of the bottom of the U-shaped frame 13 are fixedly connected to the front and rear ends of the top of the paint box 2, respectively. A first U-shaped plate 9 is provided at the bottom inside the U-shaped frame 13. The top of the first U-shaped plate 9 is slidably connected to the top of the inner wall of the U-shaped frame 13. Multiple first painting wire guide rollers 10 are rotatably connected at equal intervals to the bottom of the inner wall of the first U-shaped plate 9. A second U-shaped plate 20 is provided inside the paint box 2. Multiple second painting wire guide rollers 21 are rotatably connected at equal intervals to the top of the inner wall of the second U-shaped plate 20. The bottom of the first painting wire guide roller 10 is slidably connected to the top of the second painting wire guide roller 21.

[0030] Specifically, take-up rollers 4 and pay-off rollers 3 are respectively installed on the left and right sides of the top of the base 1 to realize the pay-off and take-up operations of the enameled wire. The top of the base 1 is equipped with an enameling mechanism, which mainly includes an enameled box 2. The enameled box 2 is fixedly installed at the center of the top of the base 1. Multiple equally spaced mounting slots 11 are symmetrically opened on the left and right sides of the top of the enameled box 2. Each mounting slot 11 is rotatably connected to a guide wheel 12 to guide the direction of the enameled wire and reduce friction damage. A U-shaped frame 13 is fixedly connected to the center of the top of the enameled box 2. The bottom front and rear ends of the U-shaped frame 13 are fixedly connected to the top front and rear ends of the enameled box 2 to enhance structural stability. A first U-shaped plate 9 is provided at the bottom of the interior of the U-shaped frame 13. The top of the first U-shaped plate 9 is connected to the U-shaped frame 13. The top of the inner wall of the frame 13 is slidably connected, allowing the first U-shaped plate 9 to slide up and down vertically, thereby achieving height adjustment. Multiple equidistant first-level paint-applying rollers 10 are rotatably connected to the bottom of the inner wall of the first U-shaped plate 9. The first-level paint-applying rollers 10 are used to complete the painting operation when the enameled wire passes through the enamel box 2. At the same time, the enamel box 2 is equipped with a second U-shaped plate 20, and multiple equidistant second-level paint-applying rollers 21 are also rotatably connected to the top of its inner wall. A sliding connection is formed between the bottom of the first-level paint-applying roller 10 and the top of the second-level paint-applying roller 21. When the enameled wire passes through, it will pass between the first-level paint-applying roller 10 and the second-level paint-applying roller 21 in sequence, so that the enameled wire can be fully coated with insulating varnish when passing through the enamel box 2.

[0031] Furthermore, this structural design, through the sliding connection of the first U-shaped plate 9, realizes the function of adjusting the distance between the first painting guide roller 10 and the second painting guide roller 21 inside the paint box 2. This allows for adjustment of the immersion depth according to different specifications of flat enameled wire, improving the adaptability of the equipment and the controllability of the painting quality, and solving the limitation problem caused by the fixed distance in the prior art.

[0032] Example 2

[0033] In the second embodiment of this utility model, a controller 25 is fixedly connected to the front surface of the paint box 2, and a first rotating shaft 301 and a second rotating shaft 401 are fixedly connected to the inner walls of the pay-off roller 3 and the take-up roller 4, respectively. Mounting brackets 101 are rotatably connected to the front and rear surfaces of the first rotating shaft 301 and the second rotating shaft 401.

[0034] Furthermore, a first motor 5 is fixedly connected to the top of the right front mounting bracket 101, the bottom of the four mounting brackets 101 is fixedly connected to the top of the base 1, and the output shaft of the first motor 5 is fixedly connected to the front end of the first rotating shaft 301.

[0035] Furthermore, the rear ends of the first rotating shaft 301 and the second rotating shaft 401 extend to the rear side of the rear mounting bracket 101 and are rotatably connected thereto. The first rotating shaft 301 and the second rotating shaft 401 are both fixedly fitted with main transmission components 6 on the rear surface of the rear mounting bracket 101, and the two main transmission components 6 are connected by a secondary transmission component 7.

[0036] Specifically, a controller 25 is fixedly connected to the front surface of the paint box 2 for centralized control of the entire painting device. A first rotating shaft 301 and a second rotating shaft 401 are fixedly connected to the inner walls of the feed roller 3 and take-up roller 4, respectively. The front and rear ends of the first rotating shaft 301 and the second rotating shaft 401 are rotatably connected to the mounting frame 101 to ensure stable rotation of the feed roller 3 and take-up roller 4, achieving smooth conveying of the enameled wire. A first motor 5 is fixedly connected to the top of the mounting frame 101 at the front right side. The bottoms of the four mounting frames 101 are fixedly connected to the top of the base 1, forming a stable support structure. The output shaft of the first motor 5 is fixedly connected to the front end of the first rotating shaft 301, driving the feed roller 3 to rotate and achieve the painting of the enameled wire. The active wire feeding control of the enameled wire involves extending the rear ends of the first rotating shaft 301 and the second rotating shaft 401 to the outside of the rear mounting bracket 101 and maintaining a rotatable connection with the rear mounting bracket 101 to ensure the stability and flexibility of the first rotating shaft 301 and the second rotating shaft 401 during operation. Main drive components 6 are fixedly sleeved on the rear surfaces of the first rotating shaft 301 and the second rotating shaft 401, respectively. The two main drive components 6 are connected by a secondary drive component 7, thereby realizing synchronous transmission between the wire feeding roller 3 and the wire take-up roller 4. This structural design can ensure good synchronization between the wire feeding and take-up processes, avoid problems such as wire stretching, slack, or breakage caused by speed mismatch, and help improve the stability and continuity of the entire enameling process.

[0037] Furthermore, after the first motor 5 starts, its output shaft rotates and drives the first rotating shaft 301 to rotate through a direct fixed connection. Since the wire feeding roller 3 is fixed on the first rotating shaft 301, the wire feeding roller 3 also rotates and begins to feed out the enameled wire. The rear ends of the first rotating shaft 301 and the second rotating shaft 401 both extend to the outside of the rear mounting bracket 101, and the rear surfaces of the first rotating shaft 301 and the second rotating shaft 401 are respectively fixedly fitted with main transmission components 6. The two main transmission components 6 are connected by a secondary transmission component 7 to form a complete power transmission chain. In this way, when the first rotating shaft 301 is driven to rotate by the first motor 5, it can be driven by the main transmission component 6 and the secondary transmission component 7. 7. Power is transmitted to the second rotating shaft 401, thereby driving the take-up roller 4 to rotate. During the process of the wire release by the wire release roller 3, the wire passes through the enamel box 2 through a specially designed path to complete the enamel coating process. As the wire release proceeds, the enamel-coated wire is collected by the rotating take-up roller 4. Because the first rotating shaft 301 and the second rotating shaft 401 maintain synchronous rotation through the main transmission component 6 and the auxiliary transmission component 7, the wire release speed and the take-up speed can be matched, avoiding excessive stretching or slack of the wire. This mechanism, through its ingenious design, realizes the automatic wire release, enamel coating and take-up of the wire, improving production efficiency and product quality.

[0038] Example 3

[0039] In the third embodiment of this utility model, a rectangular shell 14 is fixedly connected to the top of the U-shaped frame 13, and positioning plates 15 are fixedly connected to both the front and rear sides of the bottom of the U-shaped frame 13. Lifting threaded blocks 18 for vertical displacement are provided on both the front and rear surfaces of the U-shaped frame 13, and L-shaped connecting rods 19 are fixedly connected to both the front and rear surfaces of the second U-shaped plate 20. Vertical moving grooves 130 are provided on both the front and rear sides of the U-shaped frame 13.

[0040] Furthermore, the ends of the two L-shaped connecting rods 19 away from the second U-shaped plate 20 are respectively fixedly connected to the two lifting threaded blocks 18 on the side near the U-shaped frame 13. The surfaces of the two L-shaped connecting rods 19 are slidably connected to the inner wall of the moving groove 130. A vertically set electric push rod 8 is fixedly connected at the top center of the rectangular shell 14.

[0041] Furthermore, the electric push rod 8 passes through the rectangular shell 14 and extends to the lower part of the U-shaped frame 13, where it is fixedly connected to the center of the top of the first U-shaped plate 9. Vertically arranged lifting threaded rods 16 are rotatably connected between the bottom front and rear ends of the rectangular shell 14 and the top of the positioning plate 15.

[0042] Furthermore, vertically arranged guide rods 17 are fixedly connected between the bottom front and rear ends of the rectangular shell 14 and the top of the positioning plate 15. Lifting threaded rods 16 are threadedly connected to lifting threaded blocks 18. The lifting threaded blocks 18 are slidably connected to the guide rods 17. The tops of the two lifting threaded rods 16 extend to the front and rear sides of the interior of the rectangular shell 14 and are rotatably connected to them.

[0043] Furthermore, the lifting threaded rod 16 is fixedly fitted with worm gears 22 on the inner surface of the rectangular shell 14. The two worm gears 22 are meshed with the same worm 23 on one side. A second motor 24 is fixedly connected to one side of the inner wall of the rectangular shell 14. The output shaft of the second motor 24 is fixedly connected to one end of the worm 23.

[0044] Specifically, the U-shaped frame 13 is fixed to the top center of the paint box 2, and a rectangular shell 14 is fixedly connected to its top. Positioning plates 15 are provided on the front and rear sides of the bottom of the U-shaped frame 13. Lifting threaded blocks 18 that can move up and down are provided on the front and rear surfaces of the U-shaped frame 13. A vertical moving groove 130 is opened on the surface of the U-shaped frame 13 for sliding guidance of the L-shaped connecting rod 19. The electric push rod 8 is fixed to the top center of the rectangular shell 14, and its movable rod passes downward through the rectangular shell 14 and the U-shaped frame 13, and is fixedly connected to the top center of the first U-shaped plate 9 for driving the first U-shaped plate 9 to move up and down. The lifting threaded rod 16 is set vertically, and its top extends into the interior of the rectangular shell 14, and its bottom is connected to the top of the positioning plate 15. The lifting threaded rod 16 is rotatably connected to the lifting threaded block 18, which is threadedly connected to the lifting threaded block 18. The lifting threaded block 18 is simultaneously slidably engaged with the guide rod 17 to ensure stability during the lifting process. The worm gear 22 is fixedly sleeved on the top of the lifting threaded rod 16 and meshes with the worm 23 for transmission. The second motor 24 is fixed on one side of the inner wall of the rectangular shell 14, and its output shaft is fixedly connected to one end of the worm 23 to drive the entire lifting structure. The two ends of the L-shaped connecting rod 19 are respectively connected to the second U-shaped plate 20 and the lifting threaded block 18, and are slidably guided by the moving groove 130 on the U-shaped frame 13. When the lifting threaded block 18 moves up and down, the second U-shaped plate 20 is driven to lift synchronously through the L-shaped connecting rod 19.

[0045] Furthermore, the controller 25 issues an adjustment command, the second motor 24 starts, driving the worm gear 23 to rotate. The worm gear 23 drives the two meshing worm wheels 22 to rotate synchronously, thereby driving the two lifting threaded rods 16 to rotate synchronously. As the lifting threaded rods 16 rotate, the lifting threaded blocks 18 threadedly connected to them slide up and down along the guide rod 17. The lifting threaded blocks 18 drive the L-shaped connecting rod 19 to move, thereby driving the second U-shaped plate 20 to move up and down. At the same time, the electric push rod 8 is activated, pushing or pulling back the first U-shaped plate 9 to achieve the first painting. The spacing between the guide roller 10 and the second painting guide roller 21 can be adjusted by controlling the relative positions of the first U-shaped plate 9 and the second U-shaped plate 20. This allows for precise control of the immersion depth of the enameled wire as it passes through the enamel box 2. This adjustment method is suitable for flat enameled wires of different widths and thicknesses, improving the equipment's versatility and painting quality. Since the two lifting screw rods 16 are driven by the same set of worm gears 23, the synchronicity of the lifting actions on both sides is ensured. The guide rod 17 and the moving groove 130 further enhance the smoothness and precision of the entire adjustment process.

[0046] Working principle:

[0047] The enameled wire is released from the feed roller 3, which is connected to the mounting frame 101 via a first rotating shaft 301. After the first motor 5 starts, it drives the first rotating shaft 301 to rotate, causing the feed roller 3 to actively feed the wire. The rear end of the first rotating shaft 301 is connected to a main drive component 6, which is connected to the main drive component 6 on the second rotating shaft 401 via a secondary drive component 7 to achieve synchronous transmission, ensuring that the feeding speed matches the subsequent take-up speed. The released enameled wire passes sequentially through the guide rollers 12 on both sides of the top of the enamel box 2. 2. Rotary installation in mounting groove 11 serves as a guide and friction reducer, preventing damage to the enameled wire during transport. After entering the enamel box 2, the enameled wire passes between the first enameling guide roller 10 and the second enameling guide roller 21. The first enameling guide roller 10 is installed below the first U-shaped plate 9, and the second enameling guide roller 21 is installed above the second U-shaped plate 20, forming an upper and lower clamping channel. The enameled wire is completely immersed in the enamel liquid in this channel, completing uniform enameling. After enameling, the enameled wire exits the enamel box. The guide wheel 12 on the other side of the top of box 2 leads out and continues to be conveyed to the next process. It can be flexibly adjusted to accommodate flat enameled wires of different thicknesses. After the second motor 24 is started, it drives the worm gear 23 to rotate. The worm gear 23 drives the two worm wheels 22 to rotate synchronously, which in turn drives the lifting threaded rod 16 to rotate. The lifting threaded block 18 is threadedly connected to the lifting threaded rod 16 and slides up and down under the guidance of the guide rod 17. The lifting threaded block 18 drives the second U-shaped plate 20 to move up and down through the L-shaped connecting rod 19. At the same time, the electric push rod 8 pushes or pulls back the first U-shaped plate 9 to realize the independent adjustment of the position of the first painting guide roller 10. Through the above adjustment, the distance between the first painting guide roller 10 and the second painting guide roller 21 can be precisely controlled to ensure that the enamel depth of the enameled wire is moderate and the enamel layer is uniform. The enamelled wire continues to be conveyed forward and is finally collected by the take-up roller 4. Since the wire feeding and take-up speeds are consistent, problems such as wire breakage, knotting or stretching caused by inconsistent speeds during the enamel coating process are avoided.

[0048] In summary, the precise adjustment of the distance between the first U-shaped plate 9 and the second U-shaped plate 20 is achieved through components such as the electric push rod 8, the lifting threaded rod 16, the worm gear 22, the worm 23, and the second motor 24. This design allows for adjustment of the distance between the first coating guide roller 10 and the second coating guide roller 21 according to different enameled wire specifications, thereby controlling the immersion depth. The controller 25 can centrally control the entire coating process, including the wire feeding speed, the wire take-up speed, and the adjustment of the distance between the first U-shaped plate 9 and the second U-shaped plate 20. This makes operation simpler, reduces the need for manual intervention, and improves production efficiency. The first motor 5 drives the first rotating shaft 301, and the power is transmitted to the second rotating shaft 401 through the main transmission component 6 and the auxiliary transmission component 7, ensuring the synchronization of the wire feeding and take-up processes, avoiding the problem of enameled wire stretching or slack, and helping to maintain the consistency and quality stability of the enameled wire during the coating process.
