Description
Technical Field
[0001] This utility model relates to the technical field of automotive parts spraying and drying lines, specifically to an automotive parts spraying and drying line. Background Technology
[0002] An automotive parts spraying and drying line is an automated production line equipment used for the surface treatment of automotive parts. It typically consists of multiple parts, including a drying system and a conveying system. First, the conveying system sequentially feeds the sprayed parts into the drying system. In the drying system, the coating is quickly dried and cured by heating and ventilation, thus forming a firm and smooth coating. This automated operation effectively improves production efficiency and product quality, while also reducing errors and environmental pollution caused by manual operation.
[0003] Because automotive parts vary in shape and size, hooks cannot achieve a tight connection with them. The shaking generated during track operation can damage the adhesion between the sprayed paint and the surface of the parts. Under the mechanical force of the shaking, the paint gradually peels off because it cannot adhere firmly and falls to the bottom of the drying chamber. The paint accumulation is prone to drying and hardening, adhering to the bottom of the chamber and the surface of the equipment, increasing the risk of equipment corrosion and shortening its service life. The existing cleaning method is usually to manually enter the drying chamber periodically and use tools such as scrapers and brushes to scrape and sweep away the hardened paint. This method is not only inefficient and labor-intensive, but the high temperature and residual harmful gases in the drying chamber also pose a threat to the health of the operators. At the same time, frequent manual cleaning requires machine shutdown, which seriously affects the production schedule and increases operating costs. Therefore, we propose an automotive parts spraying and drying line. Utility Model Content
[0004] The purpose of this invention is to provide an automotive parts spraying and drying line to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive parts spraying and drying line, comprising a track and a drying chamber. Several hooks are installed on the surface of the track, which passes through the drying chamber. Several drying lamps are installed on the inner wall of the drying chamber. A cleaning structure is provided on the surface of the drying chamber. The cleaning structure includes two fixing plates, both of which are fixedly connected to the surface of the drying chamber. A motor is fixedly connected to the surface of each fixing plate. A rotating shaft is fixedly connected to the output end of the motor. The two rotating shafts are located at opposite ends of the drying chamber. Tracks are fitted onto the surfaces of the two rotating shafts, and the tracks are fitted onto the surface of the drying chamber.
[0006] The effect achieved by the above-mentioned components is that by setting up a cleaning structure, it is easy to remove paint dripping from the car parts from the drying chamber, thereby preventing paint from adhering to the drying chamber and ensuring the efficiency of drying the car parts.
[0007] Preferably, two fixed arms are fixedly connected to the lower surface of the drying chamber, and a scraper is fixedly connected to one side of the two fixed arms that are close to each other, and the scraper is attached to the surface of the track.
[0008] The effect achieved by the above components is that the scraper can easily remove paint from the track, thereby preventing some paint from adhering to the surface of the track.
[0009] Preferably, a cleaning roller is fixedly connected to one side of the two fixed arms that are close to each other, and the cleaning roller is in close contact with the surface of the track.
[0010] The effect achieved by the above components is that the cleaning roller further cleans the track, prevents paint from accumulating on the track, and avoids paint re-adhering to parts or other parts of the drying chamber.
[0011] Preferably, the arc surface of the rotating shaft is fixedly connected with a plurality of anti-slip strips, all of which are made of rubber.
[0012] The effect achieved by the above components is that the anti-slip strips on the arc surface of the shaft increase the friction between the shaft and the track, ensuring stable track operation and improving the cleaning effect.
[0013] Preferably, the surface of the drying chamber is provided with a limiting structure, the limiting structure including two threaded rods, the two threaded rods respectively threaded through both sides of the drying chamber, the ends of the two threaded rods that are close to each other are rotatably connected to a drive plate, the surface of the drive plate is fixedly connected to a limiting plate, and the hook is located between the two drive plates.
[0014] The effect achieved by the above components is as follows: by setting up a cleaning structure, the hook is restricted by the limiting plate when moving, thereby reducing the swing amplitude of the hook during movement, thus reducing paint peeling, limiting the swing range of the hook, avoiding problems such as component collision and paint peeling caused by hook swing, ensuring the stability of components during the drying process, and improving product quality.
[0015] Preferably, guide rods slide through the surfaces of the two drive plates, and both ends of the guide rods are fixedly connected to the inner wall of the drying chamber.
[0016] The effect achieved by the above components is that the drive plate moves along the direction of the guide rod, and the guide rod guides the drive plate to ensure its smooth movement.
[0017] Preferably, the surface of the limiting plate is provided with a groove, and the inner wall of the groove is fitted with a rubber ring.
[0018] The effect achieved by the above components is that when the hook moves, it will cause the rubber ring to slide in the groove, thereby causing the rubber ring to rotate on the surface of the limiting plate. This reduces the friction between the limiting plate and the hook, making it easier for the rubber ring to pass through the position between the limiting plates.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This invention features a cleaning structure that allows paint to drip onto the surface of the track. The cleaning structure activates, starting a motor on a fixed plate. The motor's output drives a rotating shaft, with two shafts located at opposite ends of the drying chamber. The track, fitted onto the surface of the shaft, rotates accordingly, circulating within the drying chamber and carrying away the dripping paint. The track, once removed from the drying chamber, rotates so that the paint-covered side faces downwards, allowing the paint to drip off the track surface. This facilitates the removal of paint from automotive parts from the drying chamber, preventing paint from adhering to the interior and ensuring efficient drying of the automotive parts.
[0021] By setting up a cleaning structure, the hook is restricted by the limiting plate when it moves, thereby reducing the swing amplitude of the hook during movement, which in turn reduces paint peeling, limits the swing range of the hook, and avoids problems such as parts collision and paint peeling caused by hook swinging. This ensures the stability of parts during the drying process and improves product quality. Attached Figure Description

[0029] 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.
[0030] Please see Figure 1-2 This utility model provides a technical solution: an automotive parts spraying and drying line, including a track 1 and a drying chamber 3. Several hooks 2 are installed on the surface of the track 1, which runs through the drying chamber 3. Several drying lamps 4 are installed on the inner wall of the drying chamber 3. A cleaning structure 5 is provided on the surface of the drying chamber 3. By setting the cleaning structure 5, it is possible to easily remove paint dripping from the automotive parts from the drying chamber 3, thereby preventing paint from adhering to the drying chamber 3 and ensuring the efficiency of drying the automotive parts. A limiting structure 6 is provided on the surface of the drying chamber 3. By setting the cleaning structure 5, the hooks 2 are restricted by the limiting plate 63 when moving, thereby reducing the swaying amplitude of the hooks 2 during movement, thus reducing paint fallout, limiting the swaying range of the hooks 2, and preventing problems such as parts collision and paint fallout caused by the swaying of the hooks 2, ensuring the stability of the parts during the drying process, and improving product quality.
[0031] Reference Figure 3 and Figure 4As shown in this embodiment: the cleaning structure 5 includes two fixed plates 51, both of which are fixedly connected to the surface of the drying chamber 3. A motor 52 is fixedly connected to the surface of the fixed plates 51, and a rotating shaft 53 is fixedly connected to the output end of the motor 52. The two rotating shafts 53 are located at both ends of the drying chamber 3, and a track 54 is fitted onto the surface of the two rotating shafts 53. The track 54 fits onto the surface of the drying chamber 3. Two fixed arms 55 are fixedly connected to the lower surface of the drying chamber 3. A scraper 56 is fixedly connected to the side of the two fixed arms 55 that is close to each other. The scraper 56 is in contact with the surface of the track 54, and the scraper 56 is used to scrape off the paint adhering to the track 54, thereby preventing some paint from adhering to the surface of the track 54. A cleaning roller 57 is fixedly connected to the side of the two fixed arms 55 that is close to each other. The cleaning roller 57 is in close contact with the surface of the track 54, and the cleaning roller 57 further cleans the track 54, preventing paint from accumulating on the track 54 and preventing paint from re-adhering to parts or other parts of the drying chamber 3. Several anti-slip strips 58 are fixedly connected to the arc surface of the rotating shaft 53. All anti-slip strips 58 are made of rubber. The anti-slip strips 58 on the arc surface of the rotating shaft 53 increase the friction between the anti-slip strips 58 and the track 54, ensuring the stable operation of the track 54 and improving the cleaning effect.
[0032] Reference Figure 5 and Figure 6 As shown, specifically, the limiting structure 6 includes two threaded rods 61, which are threaded through both sides of the drying chamber 3. A drive plate 62 is rotatably connected to the end of each threaded rod 61 that is close to each other. A limiting plate 63 is fixedly connected to the surface of the drive plate 62, and the hook 2 is located between the two drive plates 62. A guide rod 64 slides through the surface of the two drive plates 62. Both ends of the guide rod 64 are fixedly connected to the inner wall of the drying chamber 3. Movement of the drive plate 62 will follow the direction of the guide rod 64, which guides the drive plate 62 and ensures its smooth movement. A groove 65 is formed on the surface of the limiting plate 63, and a rubber ring 66 is fitted inside the groove 65. When the hook 2 moves, it will cause the rubber ring 66 to slide within the groove 65, thus allowing the rubber ring 66 to rotate on the surface of the limiting plate 63. This reduces the friction between the limiting plate 63 and the hook 2, facilitating the passage of the rubber ring 66 between the limiting plates 63.
[0033] Working Principle: In the operation of this automotive parts painting and drying line, the painted automotive parts are first hung on hooks 2 on track 1. Track 1 rotates, driving hooks 2 and parts to move and transport them into drying chamber 3. The drying lamps 4 on the inner wall of drying chamber 3 are turned on, releasing heat to dry the parts, allowing the paint on the surface of the parts to dry and solidify quickly, forming a firm and smooth coating. During the drying process, if any paint peels off, it will drip onto the surface of the track 54. At this time, the cleaning structure 5 starts to function, and the motor 52 on the fixed plate 51 starts. The output end of the motor 52 drives the rotating shaft 53 to rotate. The two rotating shafts 53 are located at both ends of the drying chamber 3, and the track 54 fitted on its surface rotates accordingly. The track 54 circulates within the drying chamber 3, carrying away the paint dripping from inside. As the track 54 exits the drying chamber 3, it flips, so that the paint-covered side faces downwards, allowing the paint to drip off. A scraper 56 on the fixing arm 55 on the lower surface of the drying chamber 3 adheres to the surface of the track 54, scraping away the paint. Simultaneously, a cleaning roller 57 also closely adheres to the track 54, further cleaning it and preventing paint buildup. This avoids re-adhesion of paint to parts or other parts of the drying chamber 3. Furthermore, the anti-slip strip 58 on the arc surface of the rotating shaft 53 increases friction with the track 54, ensuring stable operation of the track 54 and improving the cleaning effect.
[0034] To reduce the impact of hook 2 swaying on the components, the limiting structure 6 is activated. Rotating the threaded rod 61, whose threads penetrate both sides of the drying chamber 3, causes the drive plate 62 to move along the guide rod 64. The guide rod 64 guides the drive plate 62, ensuring smooth movement. The two drive plates 62 move closer or further apart, adjusting the distance between the two limiting plates 63, thus positioning hook 2 appropriately between the two drive plates 62. At this point, hook 2's movement is restricted by the limiting plates 63, reducing swaying during movement. The range of motion of the hook 2 is reduced, thereby reducing paint peeling and limiting the swing range of the hook 2. This prevents parts from colliding and paint from falling off due to the swing of the hook 2, ensuring the stability of the parts during the drying process and improving product quality. The rubber ring 66, which is fitted inside the groove 65 on the surface of the limiting plate 63, contacts the hook 2. When the hook 2 moves, it will drive the rubber ring 66 to slide in the groove 65, thereby causing the rubber ring 66 to rotate on the surface of the limiting plate 63. The rubber ring 66 reduces the friction between the limiting plate 63 and the hook 2, thus facilitating the passage of the rubber ring 66 between the limiting plates 63.
