[0038] Example 1

[0039] like Figures 1 to 6 As shown, this utility model embodiment provides a polishing and sealing mechanism for copper-aluminum composite coils, including a polishing assembly 3, which includes an upper polishing motor and a lower polishing motor. The upper and lower polishing motors can be synchronously driven to approach or separate each other through other synchronous drive mechanisms. This is prior art and has been disclosed in patent CN219380302U, so it will not be repeated here. The output end of the upper polishing motor is provided with an upper polishing shaft 33, and the output end of the lower polishing motor is provided with a lower polishing shaft 34. The upper polishing shaft 33 is provided with an upper polishing wheel 31, and the lower polishing shaft 34 is provided with a lower polishing wheel 32. It also includes: a housing 2, which has a cavity inside, a push-pull sealing door on the front side, and a first through groove 23 on the rear side. The upper polishing motor and the lower polishing motor are connected by a first through groove 23. The lower polishing motor is located on the outer rear side of the housing 2. The upper polishing shaft 33 and the lower polishing shaft 34 extend into the housing 2 from the first through groove 23. A sealing cover 8 is provided on the first through groove 23. The sealing cover 8 includes an upper sealing part 81 and a lower sealing part 82. The upper polishing shaft 33 passes through the upper sealing part 81, and the lower polishing shaft 34 passes through the lower sealing part 82. A middle sealing folding part 84 is provided between the upper sealing part 81 and the lower sealing part 82. The upper sealing folding part 83 is also connected above the upper sealing part 81. The top of the upper sealing folding part 83 is connected to the outer rear side of the housing 2. The lower sealing folding part 85 is also connected below the lower sealing part 82. The bottom of the lower sealing folding part 85 is connected to the outer rear side of the housing 2. An upper sealing ring 9 is provided between the upper polishing shaft 33 and the upper sealing part 81. The upper sealing ring 9 includes an outer ring 92 and an inner ring 91. The outer ring 92 is fixedly connected to the upper sealing part 81, and the outer ring 92 is rotatably connected to the inner ring 91. The inner ring 91 is sleeved on the outside of the upper polishing shaft 33. A lower sealing ring 9 is provided between the lower polishing shaft 34 and the lower sealing part 82. The structure of the lower sealing ring 9 is the same as that of the upper sealing ring 9, and will not be described in detail here.

[0040] In this embodiment of the invention, the upper polishing shaft 33 is connected to the upper sealing part 81 via the upper sealing ring 9 and can rotate relative to the upper sealing part 81. The lower polishing shaft 34 is connected to the lower sealing part 82 via the lower sealing ring 9 and can rotate relative to the lower sealing part 82. The upper sealing part 81 and the lower sealing part 82 cooperate with the upper sealing ring 9 to prevent water in the housing 2 from penetrating into the upper or lower polishing motor. When the upper polishing shaft 33 and the lower polishing shaft 34 are close to each other, the middle sealing folding part 84 is folded and compressed, while the upper sealing folding part 83 and the lower sealing folding part 85 are stretched and unfolded. When the upper polishing shaft 33 and the lower polishing shaft 34 are separated, the middle sealing folding part 84 is stretched and unfolded, while the upper sealing folding part 83 and the lower sealing folding part are not folded and compressed. In this embodiment of the invention, by setting the upper sealing folding part 83, the lower sealing folding part 85 and the middle sealing folding part 84, the upper polishing shaft 33 and the lower polishing shaft can move up and down without affecting the polishing process.

[0041] like Figure 1 As shown, the box body 2 has a second through groove 24 and a third through groove 25 on both sides; a baffle 26 is provided on the inner wall of the box body 2 near the second through groove 24. The copper-aluminum composite coil 1 is conveyed into the box body 2 for polishing through the second through groove 24 and conveyed out of the box body 2 through the third through groove 25. The baffle 26 on the inner wall of the second through groove 24 can prevent water from the water spraying assembly of the box body 2 from being sprayed out through the second through groove 24.

[0042] like Figures 1 to 4 As shown, the water spray assembly includes an upper water spray module 41 and a lower water spray module 42. The upper water spray module 41 is located near the upper polishing wheel 31, and the lower water spray module 42 is located near the lower polishing wheel 32. The upper water spray module 41 includes two sets of upper nozzles 411 arranged side by side. The lower water spray module 42 includes two sets of lower nozzles 421 arranged side by side. Both the upper nozzles 411 and the lower nozzles 421 use universal water outlet pipes. Using two sets of nozzles to spray water onto the polishing surface ensures that all surfaces in contact with the polishing surface are in contact with water, preventing damage to the structural properties of the copper-aluminum composite coil 1 due to excessive temperature. Simultaneously, the universal water pipes allow adjustment of the water spray angle, ensuring that the spray angle is precisely aligned with the polishing contact surface.

[0043] like Figure 1 and 2 As shown, a drain outlet 22 is provided at the bottom of the housing 2. An inclined surface 21 is provided at the bottom of the housing 2, extending downwards, and its bottom connects to the drain outlet 22. During the polishing process, wastewater and dust fall into the bottom of the housing 2 and are discharged from the drain outlet 22 through the inclined surface 21 at the bottom of the housing 2.

[0044] like Figures 1 to 3As shown, a drainage tank 5 is located below the housing 2, and the drainage tank 5 is connected to the drain outlet 22. The drainage tank 5 is also connected to a circulating water pipe 7, which connects to the upper spray module 41 and the lower spray module 42. A circulating water pump 6 transports the water in the drainage tank 5 to the upper spray module 41 and the lower spray module 42. Wastewater falls from the housing 2 into the drainage tank 5. When entering the drainage tank 5, a filter screen 51 is installed on the top of the drainage tank 5. The filter screen 51 is an ultra-precision filter screen that can filter polishing dust and other particles. The filtered water is then transported to the upper spray module 41 and the lower spray module 42 by a circulating water pump for reuse, making it more environmentally friendly.

[0045] like Figures 1 to 3 As shown, the circulating water pipe 7 includes a first section 71, a second section 72, a third section 73, and a fourth section 74. The first section 71 connects to the second section 72, and the second section 72 connects to the third section 73 and the fourth section 74. The first section 71 is located on the outside of the tank 2, extending from the bottom of the drain tank 5 to the top of the tank 2. The second section 72 is located inside the tank 2, extending from the top of the tank 2 into the interior of the tank 2 and fitting against the inner wall of the tank 2. The third section 73 is located inside the tank 2, near the side of the upper polishing wheel 31, and connects to the upper water spray module 41. The fourth section 74 is located inside the tank 2, near the side of the lower polishing wheel 32, and connects to the lower water spray module 42. The circulating water pipe 7 is set into four sections. The first section 71 is on the outside of the box 2, and the second section 72 is inside the box 2. The connection between the first section 71 and the second section 72 is at the top of the box 2 to avoid slotting on the side or bottom of the box 2 and to maintain the sealing and waterproof performance inside the box 2. The second section 72 extends along the inner wall of the box 2 and, without affecting the polishing structure, flows water to the third section 73 and the fourth section 74.
