Description

Technical Field

[0001] This invention relates to the field of enameled wire production technology, specifically to an enameling impregnation apparatus for enameled wire production. Background Technology

[0002] In the production of enameled wire, impregnation is a crucial step, and its quality directly affects the performance and quality of the wire. However, existing enameled wire impregnation equipment has the following problems in practical applications: When changing to a different color of paint for impregnation, existing equipment cannot quickly and thoroughly remove residual old paint from the impregnation frame. This residual paint mixes with the new paint, affecting its purity and quality, and consequently impacting the color uniformity and electrical performance of the enameled wire. Furthermore, cleaning paint adhering to components such as the impregnation frame, winding rollers, and cover plate during the impregnation process often relies on manual labor. This is not only labor-intensive and inefficient, but also makes it difficult to ensure thorough cleaning. Residual paint, once dried, increases the difficulty of subsequent cleaning and may even contaminate the next impregnation, failing to meet the needs of the workers. Summary of the Invention

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

An enamel-impregnation assembly 2 is provided inside the top of the housing 1. The enamel-impregnation assembly 2 includes an enamel-impregnation frame 205 and a winding roller 207. A cover plate assembly 3 is installed on the rear side of the top of the housing 1. The cover plate assembly 3 includes a cover plate 305. Extraction and drying assemblies 4 are provided on the left and right sides of the housing 1. The extraction and drying assemblies 4 are used to extract the paint inside the enamel-impregnation frame 205 and dry the remaining paint adhering to the inner wall of the enamel-impregnation frame 205. A second scraping assembly 6 is provided at the bottom of the inside of the housing 1 to clean the enamel-impregnation frame 205 and the winding roller 207. A first scraping assembly 5 is provided at the top of the inside of the housing 1 to clean the cover plate 305. Example 2

[0019] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, the impregnation assembly 2 also includes two sets of support plates 201 welded to the top of the inside of the housing 1. A rotating rod 202 is rotatably connected between the two sets of support plates 201. A first drive motor 203 is provided on the outer wall of one set of support plates 201 to drive the rotating rod 202 to rotate. A second electric push rod 204 is fixedly installed on the outer wall of the rotating rod 202. The bottom middle of the impregnation frame 205 is fixedly connected to the output end of the second electric push rod 204. Three sets of sleeves 206 are rotatably connected to the rear side of the inside of the impregnation frame 205. Three sets of winding rollers 207 are also provided and are threadedly connected to the inside of the three sets of sleeves 206 respectively. A hot air nozzle 208 is embedded in the inner wall of the right side of the housing 1.

[0020] Those skilled in the art will understand that the output end of the first drive motor 203 drives the rotating rod 202 to rotate, causing the second electric push rod 204 and the varnish-impregnating frame 205 to flip as a whole; when the opening of the varnish-impregnating frame 205 is vertically upward, the output end of the second electric push rod 204 is controlled to extend or retract, thereby driving the varnish-impregnating frame 205 to move upward or downward. In this invention, the winding roller 207 and the sleeve 206 are threaded together, meaning they are detachable. The sleeve 206 is rotatable, so after the winding roller 207 and the sleeve 206 are connected together, they can rotate inside the varnish-impregnated frame 205. Example 3

[0021] Please refer to Figure 1 and Figure 6 As shown, the cover plate assembly 3 includes a fixed frame 301 fixedly installed on the rear side of the top of the housing 1. A first lead screw 302 is rotatably connected inside the fixed frame 301. A cover plate 305 is threadedly connected to the first lead screw 302. The cover plate 305 is slidably connected to a first guide rod 303. The first guide rod 303 is welded inside the fixed frame 301, and the outer end of the first lead screw 302 is fixedly connected to the output end of the first stepper motor 304. The first stepper motor 304 is located on the top of the fixed frame 301.

[0022] Please refer to Figure 7 As shown, circular grooves 306 are provided through both sides of the top of the cover plate 305. Two sets of square grooves 307 are also provided on the cover plate 305. The circular grooves 306 and square grooves 307 on the same side are connected to each other. A third electric push rod 308 is installed on the front and rear sides of the interior of the square groove 307. The output end of the third electric push rod 308 is fixedly connected to the movable plate 309. A sealing block 310 is detachably connected inside the movable plate 309.

[0023] Those skilled in the art will understand that by controlling the output end of the first stepper motor 304 to rotate, the first lead screw 302 is driven to rotate, causing the cover plate 305 to move up and down along the outer wall of the first guide rod 303. During the enamel impregnation of the enameled wire, the initial end of the wire is removed from the feeding roller and passed through the circular groove 306 on the right side of the top of the cover plate 305. Then, it passes sequentially through the slots on the three winding rollers 207 in the impregnation frame 205, and exits through the circular groove 306 on the left side of the top of the cover plate 305. Finally, it is fixed to the external receiving roller. The paint is inverted in the impregnation frame 205. By controlling the output of the first stepper motor 304 to rotate, the first lead screw 302 rotates, causing the cover plate 305 to move downwards and cover the top of the impregnation frame 205. By controlling the outputs of the two sets of third electric push rods 308 in the same square groove 307 to extend or retract synchronously, the distance between the two sets of symmetrical sealing blocks 310 is adjusted, ensuring that the sealing blocks 310 are always in contact with the surface of the enameled wire during impregnation. Furthermore, the sealing blocks 310 are removable and replaceable, making the device suitable for enameled wires of different outer diameters. Example 4

[0024] Please refer to Figure 3 As shown, the exhaust drying assembly 4 includes a water pump 401 and a hot air blower 405. The water pump 401 and the hot air blower 405 are fixedly installed on the left and right sides of the housing 1, respectively. The top left and right sides of the housing 1 are respectively connected to a fourth electric push rod 402 and a fifth electric push rod 406. The output end of the fourth electric push rod 402 is fixedly connected to the water pump pipe 403. The water pump pipe 403 is connected to the first connecting pipe 404. The other end of the first connecting pipe 404 is connected to the input end of the water pump 401. The output end of the water pump 401 is connected to the external waste storage box. The output end of the fifth electric push rod 406 is fixedly connected to the air inlet pipe 407. One end of the air inlet pipe 407 is connected to the hot air nozzle 208. The other end of the air inlet pipe 407 is connected to the second connecting pipe 408. The other end of the second connecting pipe 408 is connected to the output end of the hot air blower 405.

[0025] Those skilled in the art will understand that when it is necessary to change to different paints for impregnation, the water pump 401 is started to quickly extract the paint from the impregnation frame 205. Then the hot air blower 405 is started to generate hot air and spray it into the impregnation frame 205 through the hot air nozzle 208, so that the excess paint adhering to the inner wall of the impregnation frame 205 can quickly solidify and dry. Example 5

[0026] Please refer to Figure 3 and Figure 8As shown, the first scraping assembly 5 includes a frame 501, a second lead screw 502, and a second guide rod 503. The frame 501 is welded to the top of the inner part of the housing 1. The second lead screw 502 is rotatably connected to the inside of the frame 501. The second guide rod 503 is fixedly installed inside the frame 501. A first scraper 505 is slidably connected to the second guide rod 503. The first scraper 505 is threadedly connected to the second lead screw 502. A second stepper motor 504 is provided on the outer wall of the frame 501. The outer end of the second lead screw 502 is fixedly connected to the output end of the second stepper motor 504.

[0027] Those skilled in the art will understand that the output of the second stepper motor 504 drives the second lead screw 502 to rotate, causing the first scraper 505 to reciprocate horizontally along the outer wall of the second guide rod 503. Example 6

[0028] Please refer to Figure 9 As shown, the second scraping assembly 6 includes a third lead screw 601 rotatably connected to the bottom of the housing 1. A movable frame 604 is threaded onto the third lead screw 601. The movable frame 604 is slidably connected to the third guide rod 602. The third guide rod 602 is welded to the bottom of the housing 1. A third stepper motor 603 is provided on the right side of the housing 1. The output end of the third stepper motor 603 extends into the housing 1 and is fixedly connected to the third lead screw 601. A fourth stepper motor 605 is provided on the inner wall of the movable frame 604. The output end of the fourth stepper motor 605 is fixedly connected to the fourth lead screw 606. A fourth guide rod 607 is also fixedly installed inside the movable frame 604. A movable block 608 is threaded onto the fourth lead screw 606. The movable block 608 is slidably connected to the fourth guide rod 607. A sixth electric push rod 609 and a seventh electric push rod 620 are provided on the top of the movable block 608. The output end of the seventh electric push rod 620 is fixedly connected to the second scraper 621.

[0029] Please refer to Figure 10 and Figure 11As shown, a mounting plate 610 is fixedly installed at the output end of the sixth electric actuator 609. A second drive motor 611 is provided on the outer wall of the mounting plate 610. A first drive gear 612 is fixedly connected to the output end of the second drive motor 611. A rotating disk 613 is rotatably connected inside the mounting plate 610. A first driven gear 614 that meshes with the first drive gear 612 is fixedly connected to the outer wall of the rotating disk 613. Several sets of second driven gears 617 and a set of rotating gear rings 618 are rotatably connected inside the rotating disk 613. The internal teeth of the rotating gear ring 618 mesh with several sets of second driven gears 617. The external teeth of the rotating gear ring 618 mesh with the second drive gear 616. The second drive gear 616 is fixedly connected to the output end of the third drive motor 615. The third drive motor 615 is set on the inner wall of the rotating disk 613. Several sets of clamping parts 619 are also slidably connected inside the rotating disk 613. The clamping parts 619 are respectively equipped with teeth that mesh with several sets of second driven gears 617. Three sets of threaded holes 102 are opened on the rear side of the inside of the housing 1.

[0030] Those skilled in the art will understand that the output of the third stepper motor 603 drives the third lead screw 601 to rotate, causing the movable frame 604 to reciprocate horizontally along the outer wall of the third guide rod 602, thereby driving the clamping member 619 and the second scraper 621 to reciprocate horizontally. Furthermore, the output of the fourth stepper motor 605 drives the fourth lead screw 606 to rotate, causing the movable block 608 to reciprocate back and forth along the outer wall of the fourth guide rod 607, thereby driving the clamping member 619 and the second scraper 621 to reciprocate back and forth. Moreover, by controlling the extension or retraction of the outputs of the sixth electric push rod 609 and the seventh electric push rod 620, the clamping member 619 and the second scraper 621 can reciprocate up and down. In summary, the clamping member 619 and the second scraper 621 can freely reciprocate in three dimensions: horizontal, vertical, and longitudinal.

[0031] The present invention drives the second drive gear 616 to rotate through the output end of the third drive motor 615, causing the rotating gear ring 618 to rotate. This causes all the second driven gears 617 to rotate synchronously, driving all the clamping parts 619 to move synchronously toward or away from the center of the rotating disk 613. Furthermore, under the action of the output end of the second drive motor 611, the first drive gear 612 is driven to rotate, causing the first driven gear 614 to rotate, thereby realizing the rotation of the rotating disk 613. Example 7

The bottom of the movable part 702 is in contact with the top wall of the housing 1, and a hole is provided at the bottom of the movable part 702. A third scraper 704 is provided in the hole. The third scraper 704 is detachably connected to the output end of the eighth electric push rod 703.

[0033] Please refer to Figure 2 As shown, the rear side of the interior of the housing 1 is provided with several sets of first blowers 103 inclined upward and several sets of second blowers 104 inclined downward. The bottom of the interior of the housing 1 is a slope, and a waste outlet is provided at the bottom left side of the housing 1. A cover 106 is provided on the outside of the waste outlet. The top of the cover 106 is fixedly installed on the output end of the first electric push rod 105. The first electric push rod 105 is provided on the left side wall of the housing 1.

[0034] Those skilled in the art will understand that by driving the track 701, the movable part 702 can be driven to reciprocate back and forth, thereby driving the third scraper 704 to reciprocate back and forth; and by controlling the output end of the eighth electric push rod 703 to extend or retract, the third scraper 704 can be driven to move downward or upward.

[0035] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. During the enamel impregnation of the enameled wire, the initial end of the enameled wire is removed from the feed roller and passed through the circular groove 306 on the right side of the top of the cover plate 305. Then, it passes sequentially through the slots on the three winding rollers 207 in the impregnation frame 205, and then exits through the circular groove 306 on the left side of the top of the cover plate 305. Finally, it is fixed to the external take-up roller. The enamel is inverted in the impregnation frame 205, and the output of the first stepper motor 304 is controlled to rotate, driving the first filament... The rod 302 rotates, causing the cover plate 305 to move downwards and cover the top of the enamel-impregnation frame 205. By controlling the output ends of the two sets of third electric push rods 308 in the same square groove 307 to extend or retract synchronously, the distance between the two sets of symmetrical sealing blocks 310 is adjusted so that the sealing blocks 310 are always in contact with the surface wall of the enameled wire during enamel impregnation. The sealing blocks 310 can be disassembled and replaced, making the device applicable to enamel-impregnation of enameled wires with different outer diameters. S2. When it is necessary to change to different paints for dipping, the water pump 401 is started to quickly extract the paint from the dipping frame 205. Then the hot air blower 405 is started to generate hot air and spray it into the dipping frame 205 through the hot air nozzle 208, so that the excess paint adhering to the inner wall of the dipping frame 205 can be quickly solidified and dried. After that, the output ends of the fourth electric push rod 402 and the fifth electric push rod 406 are retracted, causing the water pipe 403 to be disconnected from the dipping frame 205 and the air inlet pipe 407 to be disconnected from the hot air nozzle 208. S3. By controlling the output end of the second electric push rod 204 to retract and the output end of the stepper motor 304 to rotate, the paint impregnation frame 205 and the cover plate 305 move downward synchronously. At this time, the cover plate 305 enters the slot 101, the top of the cover plate 305 is flush with the top of the box 1, and the bottom of the cover plate 305 is flush with the inner top wall of the box 1. The paint impregnation frame 205 is located inside the box 1. Then, by controlling the output end of the first drive motor 203 to drive the rotating rod 202 to rotate, the paint impregnation frame 205 is flipped, and the opening of the paint impregnation frame 205 faces downward. S4. By driving the operation of the two sets of tracks 701, the two sets of moving parts 702 are driven to move backward synchronously, so that the center of the two sets of third scrapers 704 is concentric with the center of the circular grooves 306 on both sides. The output end of the second stepper motor 504 drives the second lead screw 502 to rotate, so that the first scraper 505 moves horizontally back and forth along the outer wall of the second guide rod 503 to scrape off the dry paint at the bottom of the cover plate 305. At the same time, the output end of the eighth electric push rod 703 extends or retracts, so as to drive the third scraper 704 to move downward or upward to scrape off the inner wall of the sealing block 310, thereby cleaning the sealing block 310 and the cover plate 305. When the several sets of inclined upward first blowers 103 blow during the cleaning process, paint debris is prevented from adhering. S5. Since both the clamping member 619 and the second scraper 621 can freely reciprocate in the horizontal, vertical, and transverse directions, by controlling the second scraper 621 to make sequential and complete contact with the outer wall of each winding roller 207 in the varnish-impregnating frame 205, and since the winding roller 207 can rotate on its own, the outer wall of each winding roller 207 is thoroughly cleaned sequentially. Then, by having all the clamping members 619 move synchronously toward the center of the rotating disk 613, the winding roller 207 can be clamped and fixed. Finally, through the combined action of the output end of the second drive motor 611 and the output end of the fourth stepper motor 605... The winding roller 207 is "screwed off" and then "screwed" into the threaded hole 102 on the rear side of the housing 1. The three sets of threaded holes 102 allow the three sets of winding rollers 207 to be placed briefly. Afterwards, since there is no obstruction from the winding roller 207 inside the paint dipping frame 205, the second scraper 621 can contact and scrape and clean each inner wall inside the paint dipping frame 205. Thus, the present invention achieves cleaning of all surfaces that can come into contact with the paint during the paint dipping process. The whole process is automated and does not require manual assistance. Moreover, the cleaned paint dipping frame 205 can be quickly immersed in paint of a different color for the next paint dipping.
