Description

Technical Field

[0001] This utility model relates to the field of rolling equipment technology, specifically a multi-roll rolling equipment for copper and aluminum foil. Background Technology

[0002] Multi-roll rolling mills for copper and aluminum foil are advanced rolling equipment used to produce high-precision metal foils. Their core structure consists of multiple precision rolls arranged in a specific configuration. Through multi-stage rolling, they achieve extremely thin metal strips. These mills typically employ four-roll, six-roll, twelve-roll, or even twenty-roll configurations, with the twenty-roll Sendzimir mill being a typical example. Utilizing small-diameter work rolls paired with a multi-stage support roll system, they significantly reduce rolling force and improve thickness control accuracy. The system is equipped with high-precision hydraulic AGC (automatic thickness control), a shape gauge closed-loop control, and constant tension control. Equipped with modules such as force winding, this machine can roll ultra-thin copper foil down to 0.005mm, with thickness tolerance controlled within ±1%. Key technological innovations include: multi-roll system dynamic stiffness compensation technology to solve the problem of roll elastic deformation; a segmented cooling system to achieve microscopic shape control; and a rolling oil mist lubrication system that balances cooling and surface quality control. This equipment is widely used in high-end fields such as lithium battery current collectors, electronic circuit copper-clad laminates, and flexible packaging, and is particularly suitable for the precision rolling requirements of high-ductility metals. Compared with traditional rolling mills, it can save 15%-20% in energy and increase the yield to over 90%. Modern models also integrate an IoT intelligent diagnostic system, enabling predictive maintenance through vibration monitoring and rolling force big data analysis, representing the cutting-edge development direction of metal foil processing equipment.

[0003] Existing multi-roller rolling equipment for copper and aluminum foil is prone to axial swaying during actual rolling due to the dynamic rolling force. This mechanical vibration directly leads to fluctuations in foil thickness and a decrease in surface flatness. Secondly, when rolling thin foil at high speed, the friction coefficient between the rolls and the foil is unstable, and the tension control system responds slowly, which can cause the foil to slip in the rolling zone. This not only causes fluctuations in rolling force but also affects the quality of foil processing. Therefore, new technical solutions need to be designed to address these issues. Utility Model Content

[0004] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-roller rolling device for copper and aluminum foil, comprising a mounting frame, six drive gears fixedly connected to one side of the mounting frame, the drive gears being arranged sequentially, six driven gears fixedly connected to one side of the mounting frame, the driven gears being arranged sequentially, the driven gears being located above the drive gears and meshing with the drive gears, and twelve rubber-metal composite rollers arranged sequentially on the inner side of the mounting frame. A tungsten carbide outer roller is fixedly connected to the outer side of the rubber-metal composite roller. The outer side of the tungsten carbide outer roller is provided with a spiral groove. Through the stabilizing mechanism, the rolling roller is prevented from axially shaking due to the dynamic rolling force during the rolling process. This prevents mechanical vibration from causing foil thickness fluctuations and a decrease in surface flatness, thereby improving the foil processing effect. Through the anti-slip mechanism, when rolling thin foil, the foil in the roller can increase the friction between the foil and the roller, preventing the foil in the roller from slipping in the rolling zone, which would lead to a decrease in foil quality.

[0006] Preferably, a connecting pin is fixedly connected to one side of both the driving gear and the driven gear. One end of the connecting pin passes through the mounting frame and extends to the inner side of the mounting frame. The driving gear and the driven gear are connected to the positioning wheel and the docking wheel through the connecting pin.

[0007] Preferably, a positioning wheel is fixedly connected to one end of the lower connecting pile, and a docking groove is provided on the outer side of the positioning wheel. The docking groove is used to dock with the docking ring to increase stability.

[0008] Preferably, a stabilizing ring is integrally formed on the inner side of the docking groove, and six rollers are rotatably connected to the outer side of the stabilizing ring. The rollers are evenly distributed and dock with the stabilizing groove through the stabilizing ring to increase stability.

[0009] Preferably, one end of the upper connecting pile passes through the mounting frame and extends to the inner side of the mounting frame, and one end of the upper connecting pile is fixedly connected to a docking wheel. The docking wheel cooperates with the positioning wheel to prevent the rolling roll from axially shaking due to the dynamic rolling force during the rolling process, which would cause mechanical vibration to lead to foil thickness fluctuations and a decrease in surface flatness.

[0010] Preferably, a docking ring is fixedly connected to the outer side of the docking wheel, the docking ring is in contact with the docking groove, and a stabilizing groove is formed on the outer side of the docking ring, the stabilizing groove is in contact with the stabilizing ring, and the docking is achieved by the stabilizing ring and the stabilizing groove, thereby increasing stability.

[0011] Preferably, three fixed brackets are fixedly connected to one side of the mounting bracket, and a motor is fixedly connected to one side of the fixed bracket. One end of the power output shaft of the motor is meshed with the drive gear. The motor drives the drive gear to rotate, which in turn drives the driven gear to rotate. A linkage gear is rotatably connected to one side of the mounting bracket, and the linkage gear meshes with the drive gear.

[0013] 1. This multi-roller rolling device for copper and aluminum foil, through a stabilizing mechanism, can prevent the rolling rolls from axially swaying due to the dynamic rolling force during the rolling process, thus preventing mechanical vibration from causing foil thickness fluctuations and a decrease in surface flatness, thereby improving the foil processing effect.

[0014] 2. This multi-roller rolling device for copper and aluminum foil, through an anti-slip mechanism, can increase the friction between the foil in the rolls and the rolls when rolling thin foil materials, preventing the foil from slipping in the rolling zone and thus reducing the quality of the foil.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4 This utility model provides a multi-roll rolling device for copper and aluminum foil, including a mounting frame 100. Six drive gears 110 are fixedly connected to one side of the mounting frame 100, and the drive gears 110 are arranged in sequence. Six driven gears 120 are fixedly connected to one side of the mounting frame 100, and the driven gears 120 are arranged in sequence. The driven gears 120 are located above the drive gears 110 and are meshed with the drive gears 110. A connecting post 130 is fixedly connected to one side of each of the drive gears 110 and the driven gears 120. One end of the connecting post 130 passes through the mounting frame 100 and extends to the inner side of the mounting frame 100. A positioning wheel 140 is fixedly connected to one end of the lower connecting post 130. A docking groove 141 is opened on the outer side of the positioning wheel 140. A stabilizing ring 150 is integrally formed on the inner side of the docking groove 141. Six rollers 151 are rotatably connected to the outer side of the mounting frame 150, and the rollers 151 are evenly distributed. One end of the upper connecting post 130 passes through the mounting frame 100 and extends to the inner side of the mounting frame 100. A docking wheel 160 is fixedly connected to one end of the upper connecting post 130. A docking ring 161 is fixedly connected to the outer side of the docking wheel 160. The docking ring 161 contacts the docking groove 141. A stabilizing groove 170 is opened on the outer side of the docking ring 161. The stabilizing groove 170 contacts the stabilizing ring 150. Three fixing frames 180 are fixedly connected to one side of the mounting frame 100. A motor 181 is fixedly connected to one side of the fixing frame 180. One end of the power output shaft of the motor 181 is meshed with the drive gear 110. A linkage gear 190 is rotatably connected to one side of the mounting frame 100. The linkage gear 190 is meshed with the drive gear 110.

[0022] Specifically, the docking groove 141 on the positioning wheel 140 contacts the docking ring 161 on the docking wheel 160, so that the docking groove 141 and the docking ring 161 cooperate to prevent the rolling roll from axially swaying under the action of dynamic rolling force during the rolling process. At the same time, the stabilizing ring 150 on the positioning wheel 140 contacts the stabilizing groove 170 on the docking wheel 160, and the roller 151 on the positioning wheel 140 reduces the friction between the positioning wheel 140 and the docking wheel 160, preventing the rolling roll from axially swaying under the action of dynamic rolling force during the rolling process.

[0023] Example 2: Please refer to again Figure 1-4 The mounting frame 100 has twelve rubber-metal composite rollers 200 arranged in sequence on the inner side. Tungsten carbide outer rollers 210 are fixedly connected to the outer side of the rubber-metal composite rollers 200. Spiral grooves 220 are opened on the outer side of the tungsten carbide outer rollers 210.

[0024] Specifically, the rubber-metal composite roller 200 can effectively suppress high-frequency vibrations during the rolling process, such as roll chatter or mechanical resonance, reduce defects such as vibration marks and scratches on the foil surface, and reduce surface roughness by 20% to 40%. Furthermore, the tungsten carbide outer roller 210 can reduce the elastic deformation of the roll, and together with the elastic inner layer, form an outer hard and inner tough structure, which reduces the fluctuation of rolling force by 20% to 40%, improves thickness consistency, and increases the friction coefficient between the tungsten carbide outer roller 210 and the foil by opening a spiral groove 220 on the outside of the tungsten carbide outer roller 210, preventing the foil from slipping inside the tungsten carbide outer roller 210.

[0025] Working principle: The docking groove 141 on the positioning wheel 140 contacts the docking ring 161 on the docking wheel 160, so that the docking groove 141 and the docking ring 161 cooperate to prevent the rolling roll from axially swaying under the action of dynamic rolling force during the rolling process. At the same time, the stabilizing ring 150 on the positioning wheel 140 contacts the stabilizing groove 170 on the docking wheel 160, and the roller 151 on the positioning wheel 140 reduces the friction between the positioning wheel 140 and the docking wheel 160, preventing the rolling roll from axially swaying under the action of dynamic rolling force during the rolling process.

[0026] The rubber-metal composite roller 200 can effectively suppress high-frequency vibrations during the rolling process, such as roll chatter or mechanical resonance, and reduce defects such as surface marks and scratches on the foil, reducing surface roughness by 20% to 40%. The tungsten carbide outer roller 210 can reduce the elastic deformation of the roll, and together with the elastic inner layer, it forms an outer hard and inner tough structure, reducing the fluctuation of rolling force by 20% to 40% and improving thickness consistency. The spiral groove 220 opened on the outside of the tungsten carbide outer roller 210 increases the coefficient of friction between the tungsten carbide outer roller 210 and the foil, preventing the foil from slipping inside the tungsten carbide outer roller 210.
