Technical Field
[0001] This utility model relates to the field of brazed finned tube processing technology, and in particular to an automatic feeding and gluing device for finned tube welding strips. Background Technology
[0002] A finned tube, also known as a heat exchanger tube, is a heat exchange element that increases its heat exchange area by adding fins to the surface of the heat exchange tube. Its main function is to improve heat exchange efficiency. The working principle of a finned tube is based on the principle of convection heat transfer. When hot air (or fluid) passes through the finned tube, a temperature difference is generated between the fin surface and the hot air, thereby generating heat transfer.
[0003] Currently, the field of finned tube welding strip coating technology lacks an efficient and flexible limiting mechanism, which reduces the stability of finned tube welding strip during the spraying process. Furthermore, when faced with finned tube welding strips of different widths, traditional devices often struggle to maintain a stable spraying effect while flexibly adjusting to adapt to different sizes of finned tube welding strips, resulting in limitations in use and overall stability. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic feeding and gluing device for finned tube welding strips.

Detailed Implementation
[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figures 1-4 As shown, the automatic feeding and gluing device for finned tube welding strip includes: a housing 1, a support 15 fixedly installed at the bottom of the housing 1 for supporting the housing 1, a door 16 installed on the front side of the housing 1 with a handle for easy opening and closing, through holes on both sides of the housing 1 for passing through the finned tube welding strip, which is similar to the aluminum fins before forming in the steel-aluminum brazed single-row finned tube disclosed in CN201974086U, and a gluing device body 2 installed inside the housing 1. The gluing device body 2 is prior art and is used to spray a thermally conductive coating or an anti-corrosion coating onto the finned tube welding strip. The spray nozzles located on both sides of the finned tube welding strip can perform a comprehensive spraying operation. Two scrapers 14 are fixedly installed inside the housing 1. Figure 2 All components are arranged at an angle. Both scrapers 14 are elastic, allowing them to adhere to both sides of the finned tube weld strip, thus scraping off excess coating. A collection box 17 is placed at the bottom of the housing 1, below the coating device body 2 and the two scrapers 14. The collection box 17 collects dripping coating for reuse, saving costs. A transmission assembly is installed inside the housing 1, including two drive rollers 8, a pressure roller 9, a shaft 10, two guide rods 12, and two springs 13. Both drive rollers 8 are rotatably mounted inside the housing 1, and each drive roller 8 is equipped with a drive motor to rotate it. The pressure roller 9 abuts against one of the drive rollers 8. The shaft 10 passes through the pressure roller 9 and rotates, with movable blocks 11 fixed at both ends. The two guide rods 12 slide through the two movable blocks 11, allowing the pressure roller to rotate. 9 can move up and down through two movable blocks 11. Both ends of the two guide rods 12 are fixedly provided with fixing plates. All four fixing plates are fixedly provided on the inner wall of the box body 1. Two springs 13 are respectively fixedly provided on the two movable blocks 11, and the top ends of the two springs 13 are respectively fixedly provided on the bottom of the fixing blocks on the same side. Limiting components are provided on both sides of the box body 1. The limiting components include a bidirectional threaded rod 4, two limiting plates 5 and a crank handle 7. Two support plates 3 are fixedly provided on one side of the box body 1. One end of the bidirectional threaded rod 4 is rotatably provided on the inner side of one of the support plates 3. Both ends of the bidirectional threaded rod 4 pass through the two limiting plates 5 and are threadedly connected to them, so that the rotation of the bidirectional threaded rod 4 can drive the two limiting plates 5 to move in the opposite direction. The other end of the bidirectional threaded rod 4 is fixedly provided with a round rod 6. The round rod 6 passes through the other support plate 3 and is rotatably provided. The crank handle 7 is fixedly provided on the outer end of the round rod 6. The crank handle 7 can facilitate the rotation of the bidirectional threaded rod 4.
[0019] Before using this utility model, the width of the finned tube weld strip to be sprayed is adjusted for practicality. The handle 7 drives the round rod 6 and the bidirectional threaded rod 4 to rotate. The bidirectional threaded rod 4 can drive the two limiting plates 5 to move simultaneously and in opposite directions, thereby adjusting the distance between the two limiting plates 5 to adapt to the finned tube weld strip to be sprayed and ensuring stability during the spraying process.
[0020] In use, the finned tube welding strip is first passed through the two through holes and placed on the two drive rollers 8. Then, the pressure rollers 9 are pressed against the finned tube welding strip by the two springs 13. Subsequently, the finned tube welding strip is moved by the two drive rollers 8. At the same time, the glue coating device body 2 is used to spray both sides of the finned tube welding strip.
