Description

Technical Field

[0001] This utility model relates to the field of aluminum surface processing technology, specifically to an aluminum surface treatment device. Background Technology

[0002] In modern industrial production, aluminum is widely used in many fields such as construction, aerospace, and automobile manufacturing due to its excellent properties such as light weight, high strength, and corrosion resistance. As various industries continue to raise their requirements for the quality and performance of aluminum products, the requirements for the precision, efficiency, and quality of aluminum surface treatment are also becoming increasingly stringent.

[0003] Chinese utility model patent with announcement number CN222035955U discloses an aluminum surface treatment device, including a support frame, one side of which is connected to a mounting plate. A cleaning unit is provided between the support frame and the mounting plate. Through the cooperation of two sets of connecting rods, cleaning rollers and connecting gears, the adhesive layer can effectively clean impurities and debris from the surface of the aluminum material when it passes through the two sets of cleaning rollers.

[0004] However, the existing aluminum surface treatment device has many limitations. In terms of cleaning methods, it can only treat a single surface or part of the surface of the aluminum material, making it difficult to clean and polish all four sides of a rectangular aluminum material simultaneously, resulting in low processing efficiency and uneven polishing. In terms of applicable size, the existing technology lacks an effective adjustment mechanism and cannot adapt to the processing needs of rectangular aluminum materials of different sizes. When processing aluminum materials with large size variations, it is often necessary to frequently change equipment or perform complex adjustments, which seriously affects the continuity and efficiency of production. In addition, during the polishing process, due to the lack of good lubrication and cooling measures, the high temperature generated during polishing can easily damage the surface of the aluminum material, reduce surface quality, and accelerate the wear of polishing tools, increasing production costs.

[0005] To overcome these problems, it is urgent to develop a device that can efficiently and accurately perform all-round surface treatment on rectangular aluminum materials of different sizes, and has good lubrication and cooling functions. Utility Model Content

On the shaft, a longitudinal cleaning roller 2 is rotatably mounted on a longitudinal cleaning support 2, and the longitudinal cleaning roller 2 is mounted on the output shaft of a longitudinal cleaning motor 2 via a longitudinal cleaning conveyor belt 2; the transverse cleaning part includes a transverse cleaning frame 1 and a transverse cleaning support 2 slidably mounted on a fixed plate in the transverse direction. The transverse cleaning frame 1 drives the transverse cleaning support 2 to move relative to each other via a transverse cleaning gear 1 and a transverse cleaning gear 2. A transverse cleaning roller 1 is rotatably mounted on the transverse cleaning frame 1, and the transverse cleaning roller 1 is mounted on the output shaft of a transverse cleaning motor 1 via a transverse cleaning conveyor belt 1. A transverse cleaning roller 2 is rotatably mounted on the transverse cleaning support 2, and the transverse cleaning roller 2 is mounted on the output shaft of a transverse cleaning motor 2 via a transverse cleaning conveyor belt 2.

[0007] Furthermore, a horizontal cleaning adjustment knob is rotatably mounted on the first horizontal cleaning frame, and the horizontal cleaning adjustment knob is threaded onto the fixed plate. Similarly, a vertical cleaning adjustment knob is rotatably mounted on the first vertical cleaning frame, and the vertical cleaning adjustment knob is threaded onto the fixed plate.

[0008] Furthermore, a lubrication section for providing lubricant is provided between the first longitudinal cleaning frame and the second longitudinal cleaning support. The lubrication section includes a lubrication nozzle 1 fixedly mounted on the first longitudinal cleaning frame and the second longitudinal cleaning support. One end of the lubrication nozzle 1 is mounted on the lubricant storage tank through a conduit, and the other end of the lubrication nozzle 1 is mounted on the second lubrication nozzle through a conduit. The second lubrication nozzle is fixedly mounted on the first transverse cleaning frame and the second transverse cleaning support.

[0009] Furthermore, the lubrication nozzle one, the conduit, and the lubrication nozzle two are all made of elastic rubber material.

[0010] Furthermore, a transmission section for transporting steel is provided on the side near the longitudinal cleaning section. The transmission section includes a transmission bracket, on which a second transmission support plate and a first transmission support plate are slidably mounted. A first transmission roller is rotatably mounted on the second transmission support plate, and a second transmission roller is rotatably mounted on the first transmission support plate. A first transmission connecting rod is rotatably mounted on the first transmission support plate, with the other end of the first transmission connecting rod rotatably mounted on the transmission plate. A second transmission connecting rod is rotatably mounted on the other end of the transmission plate, and the other end of the second transmission connecting rod is rotatably mounted on the second transmission support plate.

[0011] Furthermore, the transmission roller is fixedly mounted on the output shaft of the transmission motor, and the transmission support plate is fixedly mounted on the output shaft of the transmission cylinder.

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. Highly efficient all-around processing: This device, through the coordinated operation of its longitudinal and transverse cleaning sections, can simultaneously grind and polish all four sides of a rectangular aluminum profile in both the longitudinal and transverse directions. Compared to traditional devices that can only process a single or partial surface, this significantly improves processing efficiency. For example, when processing rectangular aluminum profiles in batches, it can significantly shorten the overall processing time, meeting the needs of large-scale production, while effectively avoiding uneven grinding caused by processing only a portion of the surface, ensuring the consistency of quality across all surfaces of the aluminum profile.

[0014] 2. Adaptable to different sizes: The longitudinal cleaning frame one and longitudinal cleaning support two, as well as the transverse cleaning frame one and transverse cleaning support two, can move relative to each other along the longitudinal and transverse directions of the fixed plate via adjusting knobs and corresponding gear structures. Operators only need to turn the longitudinal and transverse cleaning adjustment knobs to easily adjust the fit between the cleaning roller and rectangular aluminum materials of different sizes, without the need for frequent equipment changes or complex adjustments. This feature allows the device to flexibly meet the processing needs of rectangular aluminum materials with large size variations, ensuring production continuity, reducing production costs, and improving production efficiency.

[0015] 3. Excellent lubrication and cooling functions; the lubrication system plays a crucial role during the polishing process. The lubricant storage tank pumps lubricant into lubrication nozzles one and two via conduits, and the lubricant is discharged from the nozzle outlets to the polishing position. On one hand, the lubricant effectively reduces the friction between the polishing tool and the aluminum surface, reducing the heat generated during polishing and preventing damage to the aluminum surface due to high temperatures, thus improving the surface quality of the aluminum. On the other hand, the reduced friction slows down the wear rate of the polishing tool, extending its service life, thereby reducing production costs and improving economic efficiency.

[0032] like Figures 1 to 10As shown, a conveying section 5 for conveying steel is provided near the longitudinal cleaning section 1. The conveying section 5 includes a conveying cylinder 501, a first conveying support plate 502, a first conveying connecting rod 503, a conveying plate 504, a second conveying connecting rod 505, a second conveying support plate 506, a first conveying roller 507, a conveying motor 508, a second conveying roller 509, and a conveying bracket 510.

The other end of the second transmission connecting rod 505 is rotatably mounted on a second transmission support plate 506. A first transmission roller 507 is fixedly mounted on the output shaft of a transmission motor 508. A first transmission support plate 502 is fixedly mounted on the output shaft of a transmission cylinder 501. The first transmission roller 507 and the second transmission roller 509 are covered with a rubber layer to increase friction.

[0033] like Figures 1 to 10 As shown, the present invention discloses an aluminum surface treatment device. Its working principle is as follows: A rectangular aluminum material requiring surface treatment is inserted from the feed end of the outer casing 6, allowing it to enter between the first transmission roller 507 and the second transmission roller 509. The transmission cylinder 501 is activated, pushing the first transmission support plate 502 and the second transmission roller 509 towards the aluminum material. As the first transmission support plate 502 moves, it pulls the transmission plate 504 to rotate via the first transmission connecting rod 503. The rotation of the transmission plate 504 pulls the second transmission support plate 506 and the first transmission roller 507 towards the aluminum material via the second transmission connecting rod 505, causing the first and second transmission rollers 507 to contact the aluminum material. The transmission motor 508 is then activated, rotating and driving the first transmission roller 507, which in turn drives the aluminum material, thus transporting it. This device is suitable for conveying rectangular aluminum materials of different sizes.

[0034] When the aluminum material is conveyed into the hollow structure on the fixed plate 3, the operator manually rotates the longitudinal cleaning adjustment knob 102. The rotation of the knob 102 pushes the longitudinal cleaning frame 101 and the longitudinal cleaning roller 103 towards the aluminum material. The longitudinal cleaning frame 101 meshes with the longitudinal cleaning gear 106 and the longitudinal cleaning gear 2 107. As the longitudinal cleaning frame 101 moves, it causes the longitudinal cleaning support 2 108 and the longitudinal cleaning roller 2 109 to move towards the aluminum material via the longitudinal cleaning gear 106 and the longitudinal cleaning gear 2 107, ultimately... The longitudinal cleaning rollers 103 and 109 are in contact with the two sides of the rectangular aluminum material in the longitudinal direction. The longitudinal cleaning motors 104 and 110 are turned on. The rotation of the longitudinal cleaning motor 104 drives the longitudinal cleaning roller 103 to rotate through the longitudinal cleaning conveyor belt 105, polishing the top surface of the aluminum material. The rotation of the longitudinal cleaning motor 110 drives the longitudinal cleaning roller 109 to rotate through the longitudinal cleaning conveyor belt 111, polishing the bottom surface of the aluminum material.

[0035] Simultaneously, the operator rotates the lateral cleaning adjustment knob 201. The rotation of the knob 201 pushes the lateral cleaning frame 202 and the lateral cleaning roller 205 towards the aluminum material. The lateral cleaning frame 202 meshes with the lateral cleaning gears 206 and 207. As the lateral cleaning frame 202 moves, it drives the lateral cleaning support 209 and the lateral cleaning roller 208 towards the aluminum material via the lateral cleaning gears 206 and 207. Ultimately, the lateral cleaning rollers 208 and 205 come into contact with the two surfaces of the aluminum material in the lateral direction. The lateral cleaning motors 203 and 210 are then activated. The lateral cleaning motor 203 rotates, moving the lateral cleaning conveyor belt 204. The horizontal cleaning roller 205 rotates to polish one side of the aluminum material. The horizontal cleaning motor 210 rotates, which drives the horizontal cleaning roller 208 to rotate via the horizontal cleaning conveyor belt 211. The horizontal cleaning roller 208 then polishes the other side of the aluminum material, thus simultaneously processing all four sides of the rectangular aluminum material, improving processing efficiency and preventing uneven polishing. During this polishing process, the pump in the lubricant storage tank 402 is activated to pump the lubricant stored in the storage tank 402 through the conduit into the lubrication nozzles 401 and 403. The lubricant is then discharged from the outlets on the lubrication nozzles 401 and 403 to the corresponding polishing positions to achieve lubrication and cooling, ensuring polishing quality.

[0036] After polishing, the operator removes the aluminum material, completing the surface treatment.
