Description

Technical Field

[0001] This utility model relates to the field of copper foil processing technology, and in particular to a polishing device for the production of electrolytic copper foil. Background Technology

[0002] The cathode roller is a core component of the foil-making machine, a core piece of equipment for electrolytic copper foil production. It is made of titanium and is extremely prone to oxidation in an oxygen environment, forming a passivation layer. It needs to be frequently polished.

[0003] A search revealed that utility model patent document CN222843805U discloses a cathode roller polishing device, comprising: a base with a clamping groove, a receiving box mounted on the upper end of the base; a lifting mechanism mounted on both sides of the receiving box for lifting the cathode roller; a clamping and rotating mechanism mounted in the clamping groove for clamping the cathode roller and driving it to rotate; a spraying mechanism mounted on the base for wetting the cathode roller; the spraying mechanism includes a spray box mounted on the base, a spray seat mounted in the receiving box, a plurality of spray nozzles mounted on the spray seat, the spray seat being connected to the spray box via a spray pipe, and a spray pump mounted on the spray pipe; and a polishing mechanism mounted on the upper end of the base for polishing the cathode roller.

[0031] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0032] Please see Figure 1-6 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0033] like Figure 1 As shown, a polishing device for producing electrolytic copper foil includes a cathode roller body 2 and symmetrically arranged clamping machine tools 1. The clamping machine tools 1 clamp and fix the cathode roller body 2 to be processed, and drive the cathode roller body 2 to rotate, so that the circumferential surface of the cathode roller body 2 can be better polished. A polishing mechanism 4 for polishing the cathode roller body 2 is arranged on the outside of the clamping machine tools 1. A polishing liquid treatment mechanism 3 is arranged between the two clamping machine tools 1. The polishing liquid treatment mechanism 3 can collect polishing waste liquid and separate the liquid and polishing debris in the polishing liquid, which facilitates the recycling of polishing liquid.

[0034] The aforementioned clamping machine tool 1 is existing technology and will not be drawn or described in detail here.

[0035] like Figure 2-4As shown, in this embodiment, the polishing mechanism 4 includes a support platform 41, a second support plate 42, a polishing roller 48, and a protective cover 45. The support platform 41 is installed on the outer side of the clamping machine tool 1, the second support plate 42 is disposed above the support platform 41, the polishing roller 48 is disposed above the second support plate 42, and the protective cover 45 is installed on the outer side of the polishing roller 48. A connecting seat 451 is fixedly connected between the middle surface of the second support plate 42 and the protective cover 45. The protective cover 45 is used to shield the polishing roller 48 and prevent the polishing liquid from splashing during the polishing process.

[0036] A fixed seat 411 is fixedly installed on the upper end face of the support platform 41 near the side. Hinges 412 are symmetrically installed on both sides of the fixed seat 411. Hinges 43 are fixedly installed at the four included corner positions on the lower surface of the second support plate 42. Two of the hinges 43 corresponding to the hinges 412 are hinged to the hinges 412. Telescopic cylinders 441 are hinged below the other two hinges 43. Mounting seats 44 are hinged to the lower end of the fixed part of the telescopic cylinder 441. The mounting seats 44 are fixedly installed on the ground.

[0037] Specifically, the second support plate 42 is rotated at a certain angle by the telescopic cylinder 441, so that the polishing roller 48 approaches and contacts the circumferential surface of the fixed cathode roller body 2, and then the cathode roller body 2 is polished by the polishing roller 48.

[0038] like Figure 2-4 As shown, in this embodiment, support seats 47 are symmetrically fixed on the upper surface of the second support plate 42, and the polishing roller 48 is rotatably disposed between the two support seats 47. A drive motor is fixedly installed on the outer side of one of the support seats 47, and the polishing roller 48 is driven to rotate by the drive motor. The drive motor is prior art and will not be drawn or described in detail here.

[0039] like Figure 2-4 As shown, in this embodiment, the two end shafts of the cathode roller body 2 pass through the two sides of the protective cover 45 and are rotated together.

[0040] A water inlet pipe 46 is fixedly installed on the upper inner wall of the protective cover 45. One end of the water inlet pipe 46 is closed, and the other end is connected to a connecting pipe 461. The connecting pipe 461 passes through the protective cover 45 and is connected to an external polishing liquid pumping device. The water inlet pipe 46 is provided with an inclined surface. When the second support plate 42 drives the protective cover 45 to rotate to the polishing position, the inclined surface faces the cathode roller body 2. At this time, the polishing roller 48 is in contact with the circumferential surface of the cathode roller body 2, and the protective cover 45 is not in contact with the cathode roller body 2.

[0041] Several nozzles 462 connected to the water inlet pipe 46 are fixedly installed on the inclined surface of the water inlet pipe 46. The polishing liquid pumping device is existing technology and will not be drawn or described in detail here.

[0042] Specifically, the polishing liquid is pumped into the connecting pipe 461 by the polishing liquid pumping device, and then introduced into the water inlet pipe 46. Subsequently, the polishing liquid is sprayed onto the circumferential surface of the cathode roller body 2 through the nozzle 462 on the inclined surface of the water inlet pipe 46, so that the polishing roller 48 below can polish the cathode roller body 2.

[0043] like Figure 2-4 As shown, in this embodiment, an inclined water guide plate 49 is fixedly installed at the lower outlet of the protective cover 45. The polishing liquid inside the protective cover 45 can be guided to the polishing liquid treatment mechanism 3 for treatment through the water guide plate 49.

[0044] like Figure 4-6 As shown, in this embodiment, the polishing liquid treatment mechanism 3 includes a collection frame 31, a first support plate 33, and a reciprocating scraping assembly. The collection frame 31 is located directly below the cathode roller body 2 and is used to collect and process the polishing liquid and polishing debris. The first support plate 33 is fixedly installed inside the collection frame 31 and has a gap between it and the inner bottom surface of the collection frame 31, which is used to store the polishing liquid after it is separated from the polishing debris.

[0045] The first support plate 33 includes a support plate surface 331 and symmetrically arranged filter plate surfaces 332. The sieving holes on the surface of the filter plate surface 332 can separate the polishing liquid and polishing debris. An inclined plate surface connects the filter plate surface 332 and the support plate surface 331. The polishing liquid containing polishing debris on the support plate surface 331 is pushed back and forth by a reciprocating scraping component and pushed onto the filter plate surfaces 332 on both sides for filtration and separation. The separated polishing debris stays on the filter plate surface 332 and is periodically collected and processed. The separated polishing liquid enters the gap below the first support plate 33 and is recycled by a pumping device. This pumping device is prior art and will not be drawn or described in detail here.

[0046] like Figure 4-6 As shown, in this embodiment, the reciprocating scraping assembly includes a reciprocating screw 38 and a transmission roller shaft 34. The transmission roller shaft 34 is rotatably engaged with the collection frame 31 and is disposed above the first support plate 33. The transmission roller shaft 34 is in contact with the circumferential surface of the cathode roller body 2. The rotation of the cathode roller body 2 drives the rotation of the transmission roller shaft 34. The reciprocating screw 38 is rotatably engaged with the collection frame 31 and is disposed below the transmission roller shaft 34 and perpendicular to the transmission roller shaft 34.

[0047] A partition 32 is fixedly installed inside the collection frame 31. There is a gap between the partition 32 and the first support plate 33. The partition 32 is used to prevent polishing liquid from falling onto the reciprocating screw 38.

[0048] like Figure 5-6 As shown, in this embodiment, a pulley 341 is fixedly provided on one side of the circumferential surface of the transmission roller shaft 34, and a rotating shaft 39 is rotatably provided on the inner wall of the collection frame 31. A bevel gear 391 and a pulley 392 are fixedly installed on the surface of the rotating shaft 39. The pulley 341 and the pulley 392 correspond to each other, and a transmission belt 37 is installed between the pulley 341 and the pulley 392. The rotation of the transmission roller shaft 34 is transmitted to the rotating shaft 39 through the transmission belt 37.

[0049] A bevel gear 381 that meshes with a bevel gear 391 is fixedly installed on one side of the circumferential surface of the reciprocating screw 38. The rotation of the bevel gear 391 is driven by the rotating shaft 39, which in turn drives the rotation of the reciprocating screw 38.

[0050] A slider 382 is mounted on the surface of the reciprocating screw 38 to cooperate with the reciprocating screw 38. The slider 382 is in sliding cooperation with the support plate surface 331 and the partition plate 32 of the first support plate 33. A movable plate 36 is fixedly provided on the side of the slider 382. The movable plate 36 slides on the support plate surface 331 of the first support plate 33. The reciprocating screw 38 drives the slider 382 to reciprocate, so that the movable plate 36 can slide on the support plate surface 331 of the first support plate 33, thereby pushing the polishing liquid on the support plate surface 332.

[0051] like Figure 4-5 As shown, in this embodiment, a scraper 35 is provided below the cathode roller body 2 near the transmission roller shaft 34. The scraper 35 is fixed to the inner wall of the partition plate 32 and the collection frame 31, and the upper end of the scraper 35 is in contact with the circumferential surface of the cathode roller body 2. The scraper 35 can scrape most of the polishing liquid on the circumferential surface of the cathode roller body 2 onto the support plate surface 331, so as to prevent the polishing liquid from splashing outside during the rotation of the cathode roller body 2.
