Description

Technical Field

[0001] This invention relates to the field of aluminum surface treatment technology, specifically a surface cleaning device for aluminum surface pretreatment. Background Technology

[0002] Aluminum sheets, as a commonly used metal material, are widely used in engineering and construction. However, their surfaces often have defects such as oxide layers, oil stains, and scratches. These defects not only affect the aesthetics of the aluminum sheets but may also reduce their corrosion resistance and mechanical properties. Therefore, pretreatment of the aluminum sheet surface, especially grinding, is an important step in improving its surface quality and performance.

[0003] Currently available aluminum plate surface grinding equipment has many shortcomings. Some equipment struggles to grind aluminum plates evenly, resulting in inconsistent surface finish. Most aluminum plate grinding equipment on the market can only grind one side of the plate, not every side. Automation is low, requiring manual intervention to flip the plate for grinding, which leads to poor results, necessitates multiple grinding sessions, and fails to achieve even grinding. Therefore, we offer a surface cleaning device for aluminum surface pretreatment that solves these problems. Summary of the Invention

[0012] This invention provides an improved surface cleaning device for aluminum surface pretreatment, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this invention, by setting up a first conveyor belt, a strip block, a rotating rod, a pressing block, and a gear groove, firstly, the strip block moves when the first conveyor belt moves. When the strip block abuts against the pressing block, it squeezes the pressing block and drives the rotating rod to move outward. At this time, the pressing block is inserted into the gear groove in parallel, thereby driving the third pulley to rotate. Then, the fourth belt drives the eighth pulley to rotate, thereby enabling the entire flipping device to work and achieve the flipping of the aluminum plate. The subsequent grinding device then grinds the un-grinded surface of the aluminum plate, making the entire device achieve automated grinding.

[0014] Secondly, this invention, by setting up a first conveyor belt, a grinding shaft, a first stop bar, a concave plate, and a strip block, firstly, by placing an aluminum plate on the left first conveyor belt, the aluminum plate enters the grinding area under the action of the first conveyor belt. The grinding shaft and the circular grinding block grind the left and right sides and the top of the aluminum plate. When the aluminum plate enters the concave plate, because the strip block is set between the two first stop bars, the strip block will only touch the trigger mechanism when the aluminum plate enters the concave plate, thereby driving the concave plate on the circular rotating shaft to rotate and flip the aluminum plate. Finally, the aluminum plate is transported to the square hollow plate by the second conveyor belt. When the next aluminum plate abuts against the previous aluminum plate, the aluminum plate is completely squeezed out of the horizontal plate and falls between the two first stop bars on the left. The first conveyor belt on the left then transports the aluminum plate to the bottom of the left grinding shaft to grind the un-grinded part of the aluminum plate.

[0015] Thirdly, this invention, by setting up a servo motor, a first pulley, an adjustable meshing gear, a second pulley, a first belt, and a conveyor table, firstly, the servo motor drives the first pulley to rotate, then the first belt drives the second pulley to rotate, then the second pulley drives the adjustable meshing gear to rotate, and the adjustable meshing gear drives the first gear to rotate, thus enabling the first roller to work and realize the transmission of the aluminum plate. The output end of the servo motor drives a large gear to rotate, which in turn drives an adjacent small gear to rotate. The transmission shaft of the large gear drives a grinding shaft to rotate and grind the surface of the aluminum plate. The transmission shaft of the small gear drives a circular grinding block to rotate, thus achieving the grinding of the surface of the aluminum plate. The aluminum plate is polished on both sides. Then, the first roller on the left drives the sixth pulley to rotate, which in turn drives the conveyor table to rotate. The rotation of the conveyor table drives the second conveyor belt to transport the polished aluminum plate. Finally, the second roller on the right drives the transmission end of the first bevel gear to rotate. The second bevel gear meshes with the first bevel gear to drive the first roller on the left to rotate. The first roller on the left polishing table drives the third gear to rotate, which in turn drives the pinion to rotate. The pinion then drives the servo motor to rotate, thus polishing the unpolished reverse side and the front and back sides of the aluminum plate. This not only improves the smoothness of the polished aluminum plate but also achieves multiple uses in one machine. Attached Figure Description

Multiple circular grinding blocks 58 are rotatably connected to the inner wall of the grinding table 1. The drive shafts of the multiple small gears 7 pass through the side wall of the grinding table 1 and are fixedly connected to the circular grinding blocks 58. A rotating end is fixedly connected. A servo motor 8 is fixedly connected to the side wall of the grinding table 1. A first pulley 9 is fixedly connected to the output end of the servo motor 8. A triangular block 10 is fixedly connected to the side wall of the grinding table 1. A first gear 11 is rotatably connected to the side wall of the triangular block 10.

An adjustable meshing gear 12 is meshed with the first gear 11. A second pulley 13 is fixedly connected to the front end of the adjustable meshing gear 12. The same first belt 14 is fitted on the second pulley 13 and the first pulley 9. A transport table 15 is set between the two grinding tables 1. Two symmetrically arranged second rollers 16 are rotatably connected to the inner wall of the transport table 15. The same second conveyor belt 17 is mounted on the 6th floor. Multiple second baffles 18 are fixedly connected to the surface of the second conveyor belt 17. The same mounting plate 19 is fixedly connected to the side wall of the right-side grinding table 1.

A first compression spring 26 is mounted on the surface of the rotating rod 25. One end of the first compression spring 26 is fixedly connected to the surface of the rotating rod 25. The other end of the first compression spring 26 is fixedly connected to the inner wall of the square groove 24. A pressing block 27 is rotatably connected to the inner wall of the square groove 24. The pressing block 27 abuts against the rotating rod 25. The other end of the rotating rod 25 passes through the inner wall of the square groove 24 and extends to the outside. Two sets of symmetrically arranged strip columns 28 are fixedly connected to the side wall of the right grinding table 1. Two first square plates 29 are fixedly connected to the side wall of the two sets of strip columns 28. The other end of the two sets of strip columns 28 is fixedly connected to the same second strip plate 30. A circular through groove 31 is opened on the upper surface of the second strip plate 30. A circular block 32 is rotatably connected to the side wall of the second strip plate 30. A gear groove 33 is opened on the left end of the circular block 32. A third pulley 34 is fixedly connected to the surface of the gear groove 33.A strip rod 35 is fixedly connected to the surface of the rotating rod 25, and a fourth pulley 36 is slidably connected to the surface of the rotating rod 25.

[0037] Furthermore, the linkage mechanism includes a second round rod 38, one end of which passes through the side wall of the grinding table 1 and is fixedly connected to the first roller 3 on the right. A fifth pulley 39 is fixedly connected to the surface of the second round rod 38. The fifth pulley 39 and the fourth pulley 36 are fitted with the same second belt 40. The other end of the second round rod 38 is fixedly connected to a sixth pulley 41. A seventh pulley 42 is rotatably connected to the side wall of the transport table 15. The transmission rod of the seventh pulley 42 passes through the side wall of the transport table 15 and is fixedly connected to one end of the second roller 16 on the right. The seventh pulley 42 and the sixth pulley 41 are fitted with the same third belt 43. The side wall of the mounting plate 19 is provided with a third round rod 44. An eighth pulley 45 is fixedly connected to the surface of the third round rod 44. The other end of the third round rod 44 passes through the side wall of the mounting plate 19 and is fixed to the rotating end of the circular rotating shaft 20. The eighth pulley 45 and the third pulley 34 are connected by the same fourth belt 46. The side wall of the transport table 15 is rotatably connected to the first bevel gear 47. The transmission rod of the first bevel gear 47 passes through the side wall of the transport table 15 and is fixedly connected to the rotating end of the second roller 16 on the right. The first bevel gear 47 is meshed with the second bevel gear 48. The other end of the second bevel gear 48 is fixedly connected to the rotating end of the first roller 3 on the left grinding table 1. The surface of the first roller 3 on the left grinding table 1 is fixedly connected to the third gear 49. The third gear 49 is meshed with the pinion 7. Through the transmission system composed of multiple pulleys and belts, and the meshing of the first bevel gear 47 and the second bevel gear 48, the linkage mechanism can realize the efficient transmission of energy, ensure the synchronous and coordinated rotation of each part, and improve the overall working efficiency and stability.

[0038] Furthermore, a square hollow plate 50 is fixedly connected to the inner wall of the left grinding table 1, and a horizontal plate 51 is fixedly connected to the inner wall of the square hollow plate 50. The height of the horizontal plate 51 is greater than the height of the first stop bar 5, and the length of the square hollow plate 50 is greater than the length of the second conveyor belt 17. The addition of the square hollow plate 50 and the horizontal plate 51 provides stability for the transmission of the aluminum plate and makes the overall structure more stable.

[0039] Furthermore, the adjustable meshing gear 12 has multiple threaded holes 52 on its circumference. A threaded rod 53 is threadedly connected to the threaded hole 52. The other end of the threaded rod 53 is fixedly connected to a meshing tooth 54, which abuts against the first gear 11. The adjustable meshing gear 12 has multiple circular holes 55 on its circumference. A second compression spring 56 is fixedly connected to the inner wall of the circular hole 55. A circular stop 57 is fixedly connected to the other end of the second compression spring 56. The circular stop 57 abuts against the side wall of the meshing tooth 54. The end of the circular stop 57 extending to the outside is semi-circular. By rotating the threaded rod 53, the degree of meshing between the meshing tooth 54 and the first gear 11 can be adjusted. The adjustability allows the gear system to adapt to different working conditions and requirements, improving the flexibility and adaptability of the system.

[0040] Furthermore, a gear protection box 59 is provided on the side wall of the left grinding table 1. The gear protection box 59 is matched with the third gear 49, the large gear 6, and the small gear 7 respectively. Gears are important power transmission components in mechanical equipment, but they are also parts that are prone to injury. The gear protection box 59 can effectively isolate the gear parts from the outside world, preventing workers from directly contacting the gears during operation or maintenance, thereby reducing the risk of accidental injury.

[0041] Furthermore, the length of the first roller 3 on the left grinding table 1 is greater than the length of the other first roller 3 on the left grinding table 1. During use, due to the third gear 49 fixedly connected to the grinding table 1, the first conveyor belt 4 on the left will not be damaged when the third gear 49 rotates.

[0042] Furthermore, the diameter of the large gear 6 is larger than that of the small gear 7. Because the radius of the large gear 6 is larger, it can withstand greater torque, thereby transmitting greater power to the small gear 7. During grinding, because the sides of the aluminum plate are uneven, the grinding speed on the sides of the aluminum plate needs to be faster than the surface speed.

[0043] Working principle: First, the aluminum plate is placed on the first conveyor belt 4 on the left. The grinding table 1 moves the servo motor 8, and the aluminum plate enters the grinding area under the action of the first conveyor belt 4. The grinding shaft 2 and the circular grinding block 58 grind the left and right sides and top of the aluminum plate. When the aluminum plate enters the concave plate 21, the strip block 22 is set between the two first stop bars 5. Only when the aluminum plate enters the concave plate 21 will the strip block 22 touch the trigger mechanism, thereby driving the concave plate 21 on the circular rotating shaft 20 to rotate. The aluminum plate is now flipped over, and finally conveyed to the square hollow plate 50 by the second conveyor belt 17. When the next aluminum plate comes into contact with the previous one, it is completely squeezed out of the horizontal plate 51 and falls between the two first stop bars 5 on the left. The servo motor 8 drives the first pulley 9 to rotate, which in turn drives the second pulley 13 to rotate via the first belt 14. The second pulley 13 then drives the adjustable meshing gear 12 to rotate, which in turn drives the first gear 11 to rotate, causing the first roller 3 to rotate. The first roller 3 drives the aluminum plate to rotate. The output of the servo motor 8 drives the large gear 6 to rotate, which in turn drives the adjacent small gear 7 to rotate. The transmission shaft of the large gear 6 drives the grinding shaft 2 to rotate and grind the top of the aluminum plate. The transmission shaft of the small gear 7 drives the circular grinding block 58 to rotate and grind the left and right sides of the aluminum plate. The first roller 3 on the left drives the sixth pulley 41 to rotate, which in turn drives the conveyor table 15 to rotate. The rotation of the conveyor table 15 drives the second conveyor belt 17 to rotate and transport the ground aluminum plate. Finally, the second roller 16 on the right drives the transmission end of the first bevel gear 47 to rotate. The second bevel gear 48 meshes with the first bevel gear 47 and drives the first roller 3 on the left to rotate. The first roller 3 on the left grinding table 1 drives the third gear 49 to rotate, which in turn drives the small gear 7 to rotate. The small gear 7 then drives the servo motor 8 to rotate and grind the unground reverse side and the front and back sides of the aluminum plate.
