Description

Technical Field

[0001] This invention belongs to the field of electrolytic copper foil production technology, and specifically relates to a novel dewatering roller for electrolytic copper foil production. Background Technology

[0002] A novel dewatering roller for electrolytic copper foil production is a key functional component installed between the electrolytic cell outlet and subsequent drying or surface treatment processes. It efficiently removes electrolyte adhering to the surface of thin copper foil. Its basic working principle is as follows: two high-precision, acid- and alkali-resistant parallel rollers (usually stainless steel cores coated with polyurethane or Teflon) rotate synchronously in opposite directions, causing the continuously moving electrolytic copper foil to pass between them. Under the linear pressure applied by a controllable cylinder or hydraulic system, a gradually narrowing wedge-shaped extrusion zone is formed between the roller surface and the copper foil surface. Within this zone, the liquid film on the copper foil surface is subjected to intense shearing force and high pressure, forcibly squeezing out most of the electrolyte and discharging it along both sides of the roller surface, thus achieving initial dewatering.

[0003] However, in actual high-speed production processes, especially when the electrolytic current density is high, the cathode roller carries a large amount of liquid, or the viscosity of the bath liquid increases, mechanical extrusion alone is insufficient to completely remove residual moisture. This results in the copper foil still carrying a large number of droplets when it enters the drying section, which not only significantly increases heat energy consumption but also easily causes surface crystal residue, blemishes, or localized oxidation. This severely affects the surface roughness, tensile strength, and electrochemical performance of the lithium battery negative electrode current collector. To compensate for this deficiency, some existing devices wrap a water-absorbing sponge layer on the outer arc surface of the dewatering roller, attempting to assist in dehydration through capillary adsorption. However, this approach has significant drawbacks—the sponge quickly becomes saturated with water during continuous operation, losing its water absorption capacity. It may even experience "water-throwing" or "backflow" phenomena due to gravity or roller rotation, re-contaminating the clean copper foil surface with the adsorbed electrolyte. At the same time, saturated sponges are prone to microbial growth and hardening. After long-term use, they can also wear down the copper foil or shed fiber impurities, requiring frequent shutdowns for disassembly, cleaning, or replacement, which severely restricts production line continuity and product consistency. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a novel dewatering roller for electrolytic copper foil production. A high-speed fan is added to the front end of the dewatering roller, which blows directional airflow through upper and lower nozzles to pre-dehydrate the copper foil, significantly reducing the moisture content of the copper foil entering the roller, reducing the extrusion pressure, and avoiding damage to the ultra-thin foil. Furthermore, the fan is linked with the rotating column, so that the airflow is dynamically swept at an inclined angle from near to far, efficiently pushing away the water film on both sides. This can work in conjunction with the dewatering mechanism to improve dewatering efficiency and uniformity, ensuring surface cleanliness and integrity.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a novel dewatering roller for electrolytic copper foil production. The dewatering roller is set above a collection box. The upper left side of the collection box is provided with two corresponding sliding groove frames. Each sliding groove frame is provided with a sliding block inside. The two sliding blocks are corresponding in front and back. The dewatering roller includes a roller body set between the two sliding blocks and the two sliding groove frames. The two roller bodies are corresponding in vertical position. A mounting frame plate is provided on the rear side of the collection box. A mounting shell is provided on the rear side of the mounting frame plate. A fan is provided inside the mounting shell. Multiple air outlet shells are rotatably arranged inside the mounting frame plate through a rotating column. The multiple air outlet shells are connected to the interior of one mounting shell. The middle part of the air outlet shell is a retractable bellows type. An adjustment mechanism is provided on the rear side of the collection box, which is linked to the rotation of the roller body. The adjustment mechanism can reciprocate to adjust the air outlet angle of the air outlet shell.

[0006] A protective box is installed at the rear of the collection box. Inside the protective box, dovetail grooves accommodate sliding rack plates. Gears are mounted on the left ends of two rotating columns, both meshing with a rack plate. A crank is rotatably mounted on the left side of the rack plate, and a connecting rod is rotatably mounted on the left side of the crank. A rotating column is rotatably mounted on the end of the connecting rod furthest from the crank. A gear box is mounted on the rear of the collection box via a mounting plate. A bevel gear I is located inside the gear box at the left end of the rotating column. The rotating column is also rotatably connected to the protective box and the interior of the gear box. A bevel gear II, located inside the gear box, is fixedly fitted onto the outer arc surface of the lower roller. Bevel gear I meshes with bevel gear II. A first motor is installed at the front of the collection box, and the output shaft of the first motor is connected to the front end of the lower roller via a coupling.

[0007] As a further improvement of the present invention, a support frame is provided on the lower side of the collection box, and the collection box and the support frame are fixed together by welding. The support frame is provided with support feet at the four corners of its lower side.

[0008] As a further improvement of the present invention, an intercepting mesh plate is provided on the rear side of the mounting shell, and a protective plate is provided on the upper side of the collection box, with the protective plate corresponding to the front and rear positions of the two air outlet shells.

[0009] As a further improvement of the present invention, a screw is rotatably provided inside the slide frame, and the screw is located inside the rear slide frame. The sliding block located at the rear is threadedly connected to the screw, and a knob is provided at the upper end of the screw.

[0010] As a further improvement of the present invention, a drain box is provided on the lower side of the collection box, the collection box and the drain box are connected internally, and a filter screen box is slidably provided inside the drain box. A handle is provided on the front side of the filter screen box, and a drain pipe is provided on the lower side of the drain box. The drain pipe is connected internally to the drain box, and a solenoid valve is connected in series in the middle of the drain pipe.

[0011] As a further improvement of the present invention, a guide roller is rotatably provided at the upper end of the collection box, a slide rail is provided inside the collection box, two limiting plates are slidably provided inside the slide frame, the two limiting plates are adapted to the guide roller, a bidirectional lead screw is rotatably provided inside the slide rail, a second motor is provided at the rear side of the collection box, and the output shaft of the second motor is connected to the rear end of the bidirectional lead screw through a coupling.

[0012] As a further improvement of the present invention, a rubber sleeve is wrapped around the outer arc surface of the roller body, and an absorbent sponge is wrapped around the outer arc surface of each rubber sleeve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, in the dewatering operation of electrolytic copper foil, the operator first passes the copper foil to be processed between two parallel rollers, and securely fixes its end to the external winding and traction mechanism. Then, the first motor is started, and its output shaft drives the lower drive roller to rotate, which in turn drives the electrolytic copper foil to move continuously to the left through friction. Simultaneously, the movement of the copper foil drives the upper driven roller to rotate synchronously, forming a stable, slip-free clamping system. During this process, the absorbent sponges wrapped around the outer surfaces of the two rollers are in close contact with both sides of the copper foil. Under the application of appropriate linear pressure, the copper foil is not only dewatered by the machine... Mechanical extrusion forces the electrolyte adhering to the surface of the ultra-thin copper foil out, while the capillary action of the sponge further absorbs residual moisture, achieving a dual dehydration effect of "extrusion + adsorption". To adapt to the production needs of copper foil of different specifications, the device is also equipped with a precision adjustment mechanism: by rotating an external knob, the operator drives the internal screw to rotate, which in turn drives the sliding block to move up and down along the guide rail, thereby precisely adjusting the height of the upper roller and dynamically changing the gap between the two rollers. This avoids the copper foil from being stretched, deformed, indented, or even broken due to excessive pressure, while also preventing incomplete dehydration due to insufficient pressure. Crucially, the outer side of the roller's metal core is fitted with an acid- and alkali-resistant, highly elastic rubber sleeve. This rubber layer completely wraps around the roller and comes into direct contact with the absorbent sponge, effectively preventing the electrolyte contained in the sponge from physically contacting the metal roller, fundamentally preventing moisture penetration and subsequent roller corrosion.

[0014] Secondly, during the dewatering process of electrolytic copper foil, the blower is activated to generate a strong airflow by rotating the impeller at high speed. This airflow is then directed and blown at high speed onto the upper and lower surfaces of the copper foil through the air outlet casing. This process quickly peels off the attached water droplets and blows them into the collection box below for unified recycling. This not only significantly improves the overall dewatering efficiency and reduces the load on the subsequent dewatering rollers, but also effectively removes free water droplets and tiny liquid films that are difficult for the sponge to absorb, avoiding increased drying energy consumption or surface crystallization defects caused by residual moisture. At the same time, the high-speed airflow has non-contact characteristics and will not cause mechanical damage to the ultra-thin copper foil. Combined with the collection box, it enables centralized management of waste liquid, ensuring the cleanliness and physical integrity of the copper foil surface, and improving the cleanliness and environmental protection level of the production line.

[0015] Thirdly, during the rotation of the lower roller, its power is transmitted to the meshing bevel gear one through bevel gear two, which in turn drives the crank on the rotating column to rotate continuously. The crank drives the connecting rod to move, so that the rack plate can achieve stable reciprocating sliding in the dovetail groove, thereby driving the two meshing gears and their respective rotating columns to rotate synchronously. Since the front side of the air outlet shell adopts a rigid structure and is fixed to the rotating column, it can achieve periodic inclined air blowing from near to far as it swings, so that the high-speed airflow can cover the surface of the electrolytic copper foil more efficiently and evenly, quickly peel off and blow off the attached water droplets to the collection box below, significantly improving the dehydration effect. At the same time, the entire transmission mechanism—including the crank, connecting rod, rack plate and gears—is completely covered by the protective plate, effectively preventing operators from accidentally contacting moving parts and ensuring operational safety. Meanwhile, bevel gear one and bevel gear two are enclosed in a special gear box, isolating workshop dust, electrolyte mist and other impurities from intruding, avoiding gear wear, jamming or transmission failure.

[0016] Fourth, during the process of the fan drawing in external air and blowing out a high-speed airflow, the intercepting mesh plate installed at the air inlet can effectively filter dust, fibers and other impurities in the air, preventing dust-laden airflow from being directly sprayed onto the surface of the electrolytic copper foil. This avoids residual dust contaminating the ultra-thin copper foil after the moisture is blown away, ensuring its high cleanliness requirements. At the same time, the protective plate configured in the air outlet area plays a directional blocking and guiding role for water droplets carried by the high-speed airflow, confining the splashing droplets within a limited path and ensuring that they fall accurately into the collection box below. This prevents water droplets from scattering everywhere and causing equipment corrosion, slippery ground or environmental pollution. This not only improves the cleanliness and environmental friendliness of the dehydration process, but also effectively maintains the surface quality of the copper foil and the safety and cleanliness of the production site.

[0017] Fifth, in the dewatering operation of electrolytic copper foil, the copper foil is introduced through the upper end of the guide roller and passes between two dewatering rollers. During the process of high-speed airflow blowing away surface moisture and subsequent water collection, the limiting plates set on both sides can accurately center and constrain the copper foil, effectively preventing the copper foil from shifting laterally, running off-center, or even wrinkling due to airflow impact or tension fluctuations. At the same time, by controlling the operation of the second motor, its output shaft drives the bidirectional lead screw to rotate, driving the limiting plates on both sides to move closer to each other or further away from each other in the opposite direction under the guidance of the slide rail, thereby automatically adapting to electrolytic copper foil of different width specifications, achieving fast and accurate centering positioning. This not only significantly improves the flexible production capacity of the equipment and avoids manual adjustment errors, but also ensures that the copper foil is always in the optimal action area for dewatering and blowing, ensuring the uniformity of dehydration and surface integrity.

[0018] Sixth, during the squeezing and purging process, the water blown off by the high-speed airflow often carries trace amounts of electrolytic copper foil debris, which falls into the collection box and then flows into the drainage box. The filter screen installed in the drainage box can effectively intercept these copper-containing particles, preventing them from being discharged with the wastewater and causing resource waste or environmental pollution. Personnel can quickly open the drainage pipe by controlling the solenoid valve to discharge the filtered clean water in a timely manner, ensuring the continuous operation of the system. When it is necessary to recycle copper shavings, the filter screen can be pulled out entirely by simply pulling the handle, making it easy to clean and recycle the high-purity copper powder inside. This not only realizes the recycling of water resources and the standard discharge of wastewater, but also effectively recovers valuable copper resources, reduces production costs, and is simple in structure, easy to operate, and environmentally friendly.

[0022] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figures 3 and 4, a novel dewatering roller for electrolytic copper foil production is disclosed. The dewatering roller is positioned above a collection box 101. Two corresponding sliding groove frames 102 are provided on the upper left side of the collection box 101. Each sliding groove frame 102 contains a sliding block 108, with the two sliding blocks 108 corresponding in front and back positions. The dewatering roller comprises a roller body 103 positioned between the two sliding blocks 108 and the two sliding groove frames 102, with the two roller bodies 103 corresponding in vertical position. A mounting frame plate 201 is provided on the rear side of the collection box 101, and a mounting shell 202 is provided on the rear side of the mounting frame plate 201. The interior of the mounting shell 202... A fan 208 is provided. Multiple air outlet shells 203 are rotatably mounted inside the mounting frame plate 201 via a rotating column. The multiple air outlet shells 203 are connected to the interior of a mounting shell 202. The middle part of the air outlet shell 203 is a retractable accordion type. An adjustment mechanism that rotates with the roller body 103 is provided on the rear side of the collection box 101. The adjustment mechanism can reciprocate to adjust the air outlet angle of the air outlet shell 203. A screw 109 is rotatably mounted inside the slide frame 102. The screw 109 is located inside the rear slide frame 102. The sliding block 108 located at the rear is threadedly connected to the screw 109. A knob 107 is provided at the upper end of the screw 109.

[0024] The operator passes the electrolytic copper foil, which needs to be dewatered, between the two rollers 103 and fixes it to the external winding and traction mechanism. Then, the first motor 106 is turned on by the control, and the output shaft drives the lower roller 103 to rotate, causing the electrolytic copper foil to move to the left. Then, the electrolytic copper foil drives the upper roller 103 to rotate, and the water-absorbing sponge 105 squeezes away the water on both sides of the electrolytic copper foil and absorbs it, thus realizing the dewatering operation of the electrolytic copper foil. The operator can also rotate the knob 107 to drive the screw 109 to rotate, which in turn drives the roller 103 on the sliding block 108 to move up and down, thus realizing the dewatering of electrolytic copper foil of different thicknesses. The rubber sleeve 104 can isolate the water of the water-absorbing sponge 105 from contact with the roller 103, preventing the roller 103 from rusting due to contact with water.

[0025] During the process of squeezing water off the electrolytic copper foil, the blower 208 can be turned on to generate a high-speed airflow, which is then blown out at high speed through the air outlet shell 203, causing water droplets on both sides of the electrolytic copper foil to fall into the collection box 101 for collection.

[0026] like Figure 1 , 2 As shown in Figures 3 and 4, a protective box 204 is provided on the rear side of the collection box 101. A rack plate 210 is slidably mounted in a dovetail groove inside the protective box 204. Gears 209 are mounted on the left ends of two rotating columns, and both gears 209 mesh with a rack plate 210. A crank 212 is rotatably mounted on the left side of the rack plate 210, and a connecting rod 211 is rotatably mounted on the left side of the crank 212. A rotating column 213 is rotatably mounted on the end of the connecting rod 211 away from the crank 212. The rear side of the collection box 101 is connected by a mounting plate. A gearbox 205 is provided, and a bevel gear 214 located inside the gearbox 205 is provided at the left end of the rotating column 213. The rotating column 213 is also rotatably connected to the protective box 204 and the inside of the gearbox 205. A bevel gear 215 located inside the gearbox 205 is fixedly sleeved on the outer arc surface of the lower roller 103. The bevel gear 214 and the bevel gear 215 are meshed. A first motor 106 is provided on the front side of the collection box 101. The output shaft of the first motor 106 is connected to the front end of the lower roller 103 through a coupling.

[0027] When the lower roller 103 rotates, it drives the second bevel gear 215 to rotate, which in turn drives the first bevel gear 214 that meshes with it to rotate, and drives the crank 212 on the rotating column 213 to rotate. The crank 212 drives the connecting rod 211 to rotate, which in turn causes the rack plate 210 to move back and forth in the dovetail groove, causing the two gears 209 that mesh with it to rotate, which in turn causes the rotating column on the gear 209 to rotate. Since the front side of the air outlet shell 203 is made of hard material, the air inlet... The air outlet shell 203 on the rotating column can be rotated back and forth, allowing high-speed air to blow at an angle from near to far, which can quickly blow water droplets attached to the electrolytic copper foil down into the collection box 101. During operation, the protective plate 206 can shield and protect the crank 212, connecting rod 211, rack plate 210 and gear 209 to prevent easy contact by personnel, and the gear box 205 can shield and protect the bevel gear 1 214 and bevel gear 215 to prevent dust interference.

[0028] like Figure 1 , 2 As shown, an intercepting mesh plate 207 is provided on the rear side of the mounting shell 202, and a protective plate 206 is provided on the upper side of the collection box 101. The protective plate 206 corresponds to the front and rear positions of the two air outlet shells 203.

[0029] When the fan 208 draws in outside air and blows out a high-speed airflow, the intercepting mesh plate 207 can intercept the dust in the outside air, preventing the high-speed airflow from containing dust and causing dust residue to remain after the water droplets on both sides of the electrolytic copper foil are blown away. In addition, the protective plate 206 can block and intercept the water droplets blown out by the high-speed airflow, causing them to fall into the collection box 101, thus preventing the blown water droplets from running out of the collection box 101.

[0030] like Figure 1 , 2 As shown in Figure 4, a guide roller 302 is rotatably mounted on the upper end of the collection box 101. A slide rail 303 is installed inside the collection box 101. Two limiting plates 304 are slidably mounted inside the slide frame 102. The two limiting plates 304 are adapted to the guide roller 302. A bidirectional lead screw 305 is rotatably mounted inside the slide rail 303. A second motor 301 is installed on the rear side of the collection box 101. The output shaft of the second motor 301 is connected to the rear end of the bidirectional lead screw 305 through a coupling.

[0031] Personnel can also pass the electrolytic copper foil through the upper end of the guide roller 302 and between the two rollers 103. When the electrolytic copper foil is being blown or circulated with water, the limiting plates 304 on both sides can center and limit the electrolytic copper foil, preventing it from shifting out of center during the blowing and circulation process. Personnel can also control the second motor 301 to run, and the output shaft drives the bidirectional lead screw 305 to rotate, thereby causing the limiting plates 304 on both sides to move closer or further apart under the restriction of the slide rail 303, thus achieving centering and limiting of electrolytic copper foil of different widths.

[0032] According to another embodiment of the invention, such as Figure 4 , 5 As shown, a drain box 401 is provided on the lower side of the collection box 101. The collection box 101 and the drain box 401 are connected internally. A filter box 402 is slidably arranged inside the drain box 401. A handle is provided on the front side of the filter box 402. A drain pipe 403 is provided on the lower side of the drain box 401. The drain pipe 403 is connected internally to the drain box 401. A solenoid valve 404 is connected in series in the middle of the drain pipe 403.

[0033] The water blown down, mixed with a significant amount of copper foil shavings, falls into the collection box 101 and flows into the drainage box 401. The trace copper foil is intercepted by the filter screen 402 inside the drainage box 401. At the same time, personnel can open the solenoid valve 404 to allow the filtered water inside the drainage box 401 to be quickly discharged through the drain pipe 403. Then, personnel can pull out the filter screen 402 by the handle to process the trace copper foil inside, thus avoiding waste.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
