However, the drying process after coating becomes a key factor determining coating quality and production efficiency.
[0003] Most air outlets in drying units use an embedded or fixed structure, tightly connected to the air duct. The air outlet filters, grilles, and other components are installed in concealed locations, and cleaning requires the use of specialized tools to disassemble multiple components, such as air duct covers and fixing bolts. A single cleaning usually takes more than half an hour, making the operation extremely cumbersome. Utility Model Content
[0004] In view of this, the present invention provides a circulating hot air drying device for car body painting, which aims to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A circulating hot air drying device for car body painting includes:
[0007] shell;
[0008] The adjusting scraping assembly includes a fixed frame fixedly connected inside the housing. A second rotating plate and a first rotating plate are slidably connected on the fixed frame. An arc-shaped rod is slidably connected between the second rotating plate and the first rotating plate. A fixed rod is fixedly connected on the second rotating plate. A transmission rod is fixedly connected to the fixed rod via a connecting rod. A sliding block is slidably connected to the transmission rod. A scraper is fixedly connected to the sliding block via a series rod.
[0009] Furthermore, the second rotating plate is rotatably connected to the fixed frame via a second rotating shaft, and the first rotating plate is rotatably connected to the fixed frame via a third rotating shaft.
[0010] The above technical solution is adopted: by setting a second rotating shaft and a third rotating shaft, the second rotating plate and the first rotating plate can rotate more flexibly when rotating on the fixed frame.
[0011] Furthermore, both ends of the arc-shaped rod are rotatably connected to a first rotating shaft, and both ends of the arc-shaped rod are rotatably connected to the second rotating plate and the first rotating plate respectively through the first rotating shaft and the arc-shaped rod.
[0012] The above technical solution is adopted: by setting an arc-shaped rod to connect the first rotating plate and the second rotating plate, it is convenient for the first rotating plate and the second rotating plate to transmit power to each other during use.
[0013] Furthermore, a slanted groove is provided on the side of the sliding block near the transmission rod, and the transmission rod is slidably connected in the slanted groove on the sliding block. An opening is provided on the side of the sliding block near the connecting rod, and the connecting rod is slidably connected in the opening on the sliding block.
[0014] The above technical solution is adopted: by opening an inclined groove on the side of the sliding block near the transmission rod, it is convenient to guide the transmission block by sliding the transmission rod in the inclined groove on the sliding block during use.
[0015] Furthermore, a transverse groove is provided inside the outer casing on the side near the sliding block, and the sliding block is slidably connected in the transverse groove inside the outer casing.
[0016] The above technical solution is adopted: by setting a sliding groove on the side of the outer shell near the sliding block, the sliding block can slide in it during use, and the sliding groove plays a limiting role to prevent the sliding block from falling off.
[0017] Furthermore, a round rod is fixedly connected to the fixed frame, and two fixed frames are provided. The two fixed frames are fixedly connected to each other by the round rod, and the two ends of the fixed rod are respectively fixedly connected to the second rotating plates on both sides.
[0018] The above technical solution is adopted: a round rod is provided, which is fixed inside the outer shell, and the fixing frame is fixed inside the outer shell by the round rod, so that a certain distance is left between the fixing frame and the inner shell.
[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a circulating hot air drying device for vehicle body painting, which has the following beneficial effects:
[0020] In this invention, the cleaning of the air outlet is achieved using the self-powered hot air. When air begins to blow inside the outer casing, the tilted second rotating plate rotates flexibly within the fixed frame via a second rotating shaft under the action of the hot air. As the second rotating plate rotates, it drives the first rotating plate, which is connected to it via an arc-shaped rod. The first rotating plate also rotates within the fixed frame via a third rotating shaft. Both ends of the arc-shaped rod are rotatably connected to the second and first rotating plates respectively via the first rotating shaft, ensuring stable and efficient transmission. During this process, the fixed rod on the second rotating plate drives the transmission rod to move via a connecting rod. The transmission rod slides within the inclined groove of the sliding block. Since the inclined groove is located on the side of the sliding block near the transmission rod, it serves as a guide. Simultaneously, an opening is located on the side of the sliding block near the connecting rod, allowing the connecting rod to slide within it. Under the action of the transmission rod, the sliding block is moved within the transverse groove of the outer casing, preventing it from falling off. The sliding block then drives the scraper to slide at the air outlet of the outer casing via a connecting rod, scraping away the dust at the air outlet. The entire cleaning process requires no manual disassembly of parts and no additional power, solving the problem of manual cleaning required in the prior art. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example:
[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a circulating hot air drying device for vehicle body painting, comprising:
[0035] Outer shell 1;
[0036] Adjust the scraping assembly 2. The scraping assembly 2 includes a fixed frame 21 fixedly connected to the outer shell 1. A second rotating plate 23 and a first rotating plate 22 are slidably connected to the fixed frame 21. An arc-shaped rod 24 is slidably connected between the second rotating plate 23 and the first rotating plate 22. A fixed rod 26 is fixedly connected to the second rotating plate 23. A transmission rod 211 is fixedly connected to the fixed rod 26 through a connecting rod 27. A sliding block 28 is slidably connected to the transmission rod 211. A scraper 210 is fixedly connected to the sliding block 28 through a series rod 29.
[0037] In this utility model, when the air blows inside the outer casing 1, the inclined second rotating plate 23 will be blown to rotate inside the fixed frame 21, causing the arc rod 24 to be displaced by transmission, which in turn drives the first rotating plate 22 to rotate inside the fixed frame 21 through the third rotating shaft 31. At this time, the connecting rod 27 will drive the transmission rod 211 to slide inside the sliding block 28, causing the sliding block 28 to be displaced under the limiting action of the inclined groove, so that the sliding block 28 drives the scraper 210 to slide at the air outlet on the outer casing 1 through the connecting rod 29, thus scraping off the dust.
[0038] The outlet is cleaned using the power of hot air itself. When air begins to blow inside the outer casing 1, the tilted second rotating plate 23 rotates flexibly within the fixed frame 21 via the second rotating shaft 3 under the action of the hot air. As the second rotating plate 23 rotates, it drives the first rotating plate 22, which is connected to it via an arc-shaped rod 24. The first rotating plate 22 also rotates within the fixed frame 21 via the third rotating shaft 31. The two ends of the arc-shaped rod 24 are rotatably connected to the second rotating plate 23 and the first rotating plate 22 via the first rotating shaft 25, ensuring stable and efficient transmission. During this process, the fixed rod 26 on the second rotating plate 23 drives the transmission rod 211 to move via the connecting rod 27. The transmission rod 211 slides within the inclined groove of the sliding block 28. Because the sliding block 28 is close to the transmission rod... A slanted groove is provided on one side of the sliding block 211 to serve as a guide. Simultaneously, an opening is provided on the sliding block 28 near the connecting rod 27, through which the connecting rod 27 slides. Under the action of the transmission rod 211, the sliding block 28 is displaced within the transverse groove of the outer casing 1 to prevent it from falling off. The sliding block 28 then drives the scraper 210 to slide at the air outlet of the outer casing 1 via the connecting rod 29, scraping away dust from the air outlet. The entire cleaning process requires no manual disassembly of parts and no additional power, solving the problem of manual cleaning required in the prior art.
[0039] Furthermore, such as Figures 1 to 5 As shown, the second rotating plate 23 is rotatably connected to the fixed frame 21 via the second rotating shaft 3, and the first rotating plate 22 is rotatably connected to the fixed frame 21 via the third rotating shaft 31. By setting the second rotating shaft 3 and the third rotating shaft 31, a stable and flexible rotating pair structure is constructed, which effectively reduces the mechanical resistance of the second rotating plate 23 and the first rotating plate 22 when rotating in the fixed frame 21, significantly improves the smoothness and reliability of the transmission process, and ensures the stability of the device operation.
[0040] Both ends of the arc-shaped rod 24 are rotatably connected to the first rotating shaft 25. The two ends of the arc-shaped rod 24 are rotatably connected to the second rotating plate 23 and the first rotating plate 22 respectively through the first rotating shaft 25 and the arc-shaped rod 24. By setting the arc-shaped rod 24 to connect the first rotating plate 22 and the second rotating plate 23, the impact and vibration during the movement can be effectively absorbed. At the same time, during the transmission process at different angles, the power transmission is ensured to be efficient, and the overall transmission efficiency and stability are improved.
[0041] A groove is provided on the side of the sliding block 28 near the transmission rod 211. The transmission rod 211 is slidably connected in the groove on the sliding block 28. An opening is provided on the side of the sliding block 28 near the connecting rod 27. The connecting rod 27 is slidably connected in the opening on the sliding block 28. By providing a groove on the side of the sliding block 28 near the transmission rod 211, a guiding mechanism is established. During the sliding process of the transmission rod 211 in the groove, the sliding block 28 is guided by the inclined surface constraint, ensuring the accuracy of its motion trajectory and effectively avoiding motion deviation.
[0042] like Figure 1 As shown, a transverse groove is provided inside the housing 1 on the side near the sliding block 28. The sliding block 28 is slidably connected in the transverse groove inside the housing 1. By providing a transverse groove on the side of the housing 1 near the sliding block 28, a limiting structure is constructed. The transverse groove provides a stable movement track for the sliding block 28, ensuring its smooth sliding while effectively preventing the sliding block 28 from falling off during movement, thus improving the safety of the device operation.
[0043] like Figures 2 to 3 As shown, a round rod 4 is fixedly connected to the fixed frame 21. There are two fixed frames 21, which are fixedly connected by the round rod 4. The two ends of the fixed rod 26 are fixedly connected to the second rotating plates 23 on both sides. By setting the round rod 4, a stable support structure is formed inside the outer shell 1. The round rod 4 rigidly connects the two fixed frames 21, which not only ensures the installation accuracy of the fixed frame 21 inside the outer shell 1, but also reserves a reasonable space between the fixed frame 21 and the outer shell 1, providing sufficient movement space for the internal transmission components.
