Description
Technical Field
[0001] This utility model relates to the field of coating equipment technology, specifically a synchronous coating device for double-sided coating of rust-proof aluminum strip. Background Technology
[0002] Aluminum strip is a basic industrial material made from pure aluminum or aluminum alloy cast-rolled or hot-rolled aluminum coils through cold rolling and slitting processes. Aluminum strip products include pure aluminum strip, rust-resistant aluminum strip, and super-hard aluminum strip. To improve the corrosion resistance of rust-resistant aluminum strip, an anti-corrosion coating is usually applied to the surface of the aluminum strip. The coating application device is used to apply the anti-corrosion coating to the surface of the rust-resistant aluminum strip.
[0003] Existing anti-rust aluminum strip coating equipment can only coat one side of the aluminum strip at a time. When both sides of the aluminum strip are coated, the two sides need to be coated twice. This two-coating method not only reduces work efficiency but also greatly increases production costs.
[0004] Therefore, this utility model provides a device for synchronous scraping of double-sided coating on rust-proof aluminum strip to solve the above problems. Utility Model Content
[0005] This utility model provides a synchronous scraping device for double-sided coating of rust-proof aluminum strip, which aims to solve the problems mentioned in the background art, such as the existing rust-proof aluminum strip scraping device can only scrape one side of the aluminum strip at a time. When scraping both sides of the aluminum strip, the two sides of the aluminum strip need to be scraped twice. The two-scraping method not only reduces work efficiency, but also greatly increases production costs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rust-proof aluminum strip double-sided coating synchronous scraping device, including a workbench, a conveying structure and a scraping structure disposed on the end face of the workbench are symmetrically installed on the end face of the workbench, a support frame is installed on the end face of the workbench and on the right side of the scraping structure, and a leg column is installed on the support frame. The conveying structure includes a mounting frame, on which a first rotating roller is rotatably mounted via bearings on the front and rear sides of the mounting frame, and on which a second rotating roller is rotatably mounted via bearings on the front and rear sides of the mounting frame and below the first rotating roller. A main gear is provided at the front end of the first rotating roller, and a secondary gear is provided at the front end of the second rotating roller. The coating structure includes a coating box. A first guide roller and two sets of second guide rollers are rotatably mounted on the front and rear sides of the coating box via bearings. A U-shaped frame and two sets of L-shaped rods symmetrically arranged on the upper end of the coating box are mounted on the upper end. A first scraper is mounted on the side wall of the U-shaped frame. The other ends of the two sets of L-shaped rods are connected by a fixing plate, and a second scraper is mounted on the side wall of the fixing plate. By setting up the conveying and coating structures, the function of simultaneously coating both sides of the aluminum strip with an anti-corrosion coating is achieved. This avoids the problem that existing anti-rust aluminum strip coating devices can only coat one side of the aluminum strip at a time, requiring two separate coating processes when both sides are coated. This improves the coating efficiency of the aluminum strip and thus reduces production costs.
[0007] Preferably, the drying structure includes a drying chamber, an upper heating plate is installed on the inner end face of the drying chamber, and a lower heating plate is installed on the bottom of the inner cavity of the drying chamber.
[0008] Preferably, the lower end of the mounting bracket is connected to the end face of the workbench, and the main gear and the auxiliary gear are connected by meshing.
[0009] Preferably, a servo motor is installed at the rear end of the first roller, and the servo motor is connected to the back of the mounting bracket by bolts.
[0010] Preferably, the bottom of the paint box is connected to the end face of the workbench, and vertical plates are rotatably mounted on the front and rear ends of the second guide roller via bearings, with the bottom of the vertical plates connected to the upper end of the workbench.
[0011] Preferably, the first scraper and the second scraper are on the same horizontal line, the first scraper and the second scraper are installed at an angle, and the bottom of the workbench and at the corner are equipped with a leg column.
[0012] Preferably, the bottom of the drying box is connected to the upper surface of the support frame, the left side wall of the drying box has an inlet, and the right side wall of the drying box has an outlet.
[0013] Beneficial effects: By setting up a conveying structure and a scraping structure, and using the first rotating roller, the second rotating roller, the first guide roller, the second guide roller, the first scraper, and the second scraper in combination, the function of simultaneously scraping and applying anti-corrosion coating to both sides of the aluminum strip can be achieved. This avoids the problem that existing anti-rust aluminum strip scraping devices can only scrape one side of the aluminum strip at a time, and that when scraping both sides of the aluminum strip, both sides of the aluminum strip need to be scraped twice. This improves the scraping efficiency of the aluminum strip coating, thereby reducing production costs. Attached Figure Description

[0016] 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.
[0017] Example 1 This embodiment provides a device for synchronously scraping and coating rust-proof aluminum strips on both sides, such as... Figure 1-4 As shown, the scraping device includes a workbench 1, a conveying structure 2 and a scraping structure 3 symmetrically mounted on the end face of the workbench 1, a support frame 5 mounted on the end face of the workbench 1 and located on the right side of the scraping structure 3, and a leg column 6 mounted on the support frame 5. The conveying structure 2 includes a mounting frame 21. A first roller 22 is rotatably mounted on the front and rear sides of the mounting frame 21 via bearings. A second roller 23 is rotatably mounted on the front and rear sides of the mounting frame 21 and below the first roller 22 via bearings. A main gear 24 is provided at the front end of the first roller 22, and a secondary gear 25 is provided at the front end of the second roller 23. The coating structure 3 includes a paint box 31. The front and rear sides of the inner cavity of the paint box 31 are rotatably mounted with a first guide roller 32 and two sets of second guide rollers 33 rotatably mounted on the paint box 31 via bearings. A U-shaped frame 34 and two sets of L-shaped rods 35 symmetrically arranged on the upper end of the paint box 31 are mounted on the upper end of the paint box 31. A first scraper 36 is mounted on the side wall of the U-shaped frame 34. The other ends of the two sets of L-shaped rods 35 are connected by a fixing plate 37. A second scraper 38 is mounted on the side wall of the fixing plate 37.
[0018] In use, the aluminum strip enters between the first right roller 22 and the second right roller 23, then moves sequentially to the upper outer wall of the second left guide roller 33, the lower outer wall of the first guide roller 32, the middle of the first scraper 36 and the second scraper 38, and the upper outer wall of the second right guide roller 33. Finally, it exits between the first right roller 22 and the second right roller 23. The control panel activates the two sets of servo motors 26 to rotate synchronously. The servo motors 26 drive the first roller 22 to rotate counterclockwise, which in turn drives the main gear 24. The main gear 24 drives the secondary gear 25 to rotate in the opposite direction, and the secondary gear 25 drives the second roller 23 to rotate clockwise. This process is repeated between the two rollers. The side conveyor structure 2 conveys the aluminum strip. The aluminum strip enters the paint box 31, so that both sides of the aluminum strip are covered with paint. Then, the aluminum strip with both sides covered with paint passes between the first scraper 36 and the second scraper 38. The first scraper 36 and the second scraper 38 scrape the paint on both sides of the aluminum strip and scrape off the excess paint. This realizes the function of simultaneously applying the anti-corrosion coating to both sides of the aluminum strip. This avoids the problem that the existing anti-rust aluminum strip coating device can only coat one side of the aluminum strip at a time. When both sides of the aluminum strip are coated, the two sides of the aluminum strip need to be coated twice. This improves the coating efficiency of the aluminum strip and thus reduces production costs.
[0019] In this embodiment, the bottom of the paint box 31 is connected to the end face of the workbench 1, and the front and rear ends of the second guide roller 33 are rotatably mounted with vertical plates 311 through bearings. The bottom of the vertical plates 311 is connected to the upper end of the workbench 1. The first scraper 36 and the second scraper 38 are on the same horizontal straight line. The first scraper 36 and the second scraper 38 are installed at an angle. The bottom of the workbench 1 and at the corner are mounted with leg columns 6. The first scraper 36 and the second scraper 38 are positioned on the same horizontal straight line, allowing them to simultaneously scrape and coat both sides of the aluminum strip, resulting in a consistent coating on both sides. Furthermore, the first scraper 36 and the second scraper 38 are installed at an angle, ensuring that any excess coating scraped off the two sides of the aluminum strip flows back into the coating box 31 along the angled surfaces of the first scraper 36 and the second scraper 38. In this embodiment, the lower end of the mounting frame 21 is connected to the end face of the workbench 1, and the main gear 24 and the auxiliary gear 25 are connected by meshing; a servo motor 26 is installed at the rear end of the first roller 22, and the servo motor 26 is connected to the back of the mounting frame 21 by bolts.
[0020] Example 2 Unlike Example 1, the existing anti-rust aluminum strip coating device does not have the function of drying the aluminum strip coating after coating. It is necessary to add a separate drying setting to dry the aluminum strip coating, which requires more equipment investment and increases production costs. Therefore, the drying structure 4 includes a drying box 41, an upper heating plate 42 is installed on the inner end face of the drying box 41, and a lower heating plate 43 is installed on the bottom of the inner cavity of the drying box 41. In use, a drying structure 4 is set between the first scraper 36 on the right and the conveying structure 2 on the right. After moving out from the upper outer wall of the first scraper 36 on the right, it enters the inlet 411 and then passes through the upper heating plate 42 and the lower heating plate 43. The upper heating plate 42 and the lower heating plate 43 heat the air inside the drying chamber 41, thereby drying the aluminum strip coating that passes through the upper heating plate 42 and the lower heating plate 43. After drying, the coated aluminum strip passes out from the outlet 412 and enters the first roller 22 and the second roller 23 on the right. This avoids the problem that the existing anti-rust aluminum strip scraping device does not have the function of drying the coated aluminum strip coating and requires the addition of a separate drying device to dry the aluminum strip coating. The anti-rust aluminum strip scraping and coating realizes the functions of double-sided scraping and coating drying of aluminum strip, thereby reducing equipment and saving production costs, making the anti-rust aluminum strip double-sided coating synchronous scraping device more effective. In this embodiment, the bottom of the drying box 41 is connected to the upper surface of the support frame 5, the left side wall of the drying box 41 has an inlet 411, and the right side wall of the drying box 41 has an outlet 412.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
