Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, specifically to a rolling equipment for producing stainless steel foil with an added lubrication function. Background Technology

[0002] Stainless steel foil is an ultra-thin, flat product made of stainless steel material through precision rolling, annealing, and finishing processes. It has excellent corrosion resistance, ductility, and surface precision, and is a key basic material in high-end manufacturing.

[0003] Currently, ensuring that the edges of the rolled stainless steel foil remain wrinkle-free during operation remains a technical challenge for most stainless steel foil rolling equipment on the market. Furthermore, during long-term use, the surface of the rolling rolls may undergo slight deformation due to temperature or other factors. This deformation is difficult to detect with the naked eye but results in a slightly wavy surface on the rolled stainless steel foil, affecting rolling precision and the quality of the finished product. Therefore, we need a stainless steel foil rolling equipment with lubrication capabilities to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a rolling equipment for producing stainless steel foil with an added lubrication function, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The rolling mill includes a support frame, unwinding rolls, unwinding guide rolls, take-up rolls, take-up guide rolls, anti-wrinkle modules, a primary rolling mill unit, a roll smoothing unit, and a secondary rolling mill unit. The unwinding rolls are rotatably connected to the support frame and are located at one end of the support frame. The take-up rolls are rotatably connected to the support frame and are located at the other end of the support frame. The unwinding guide rolls are rotatably connected to the support frame and are located between the unwinding rolls and the take-up rolls. The take-up guide rolls are rotatably connected to the support frame and are located between the unwinding guide rolls and the take-up rolls. The anti-wrinkle modules are fixedly connected to the support frame and are located on both sides of the primary rolling mill unit. Between the guide roller and the secondary roll unit, the primary roll unit and the support frame are rotatably connected. The primary roll unit is located inside the roll smoothing unit. The roll smoothing unit and the support frame are fixedly connected. The roll smoothing unit is located between the secondary roll unit and the unwinding guide roller. The secondary roll unit and the support frame are rotatably connected. The secondary roll unit is located between the unwinding guide roller and the winding guide roller. During rolling, the stainless steel foil passes sequentially below the unwinding roller, above the unwinding guide roller, through the anti-wrinkle module, the roll smoothing unit, the primary roll unit, the roll smoothing unit, the anti-wrinkle module, the secondary roll unit, below the winding guide roller, and above the winding roller.

[0006] The unwinding roll is used for unwinding stainless steel foil, and the take-up roll is used for taking it back. Both the unwinding and take-up rolls are driven by a motor. The unwinding guide roll and the take-up guide roll provide a rolling path for the stainless steel foil while also providing a certain tension. The anti-wrinkle module is used to prevent wrinkles from forming at the edges of the stainless steel foil during the rolling process, ensuring that the surface of the rolled product is smooth and flat. The primary rolling unit is used to perform the initial rolling of the stainless steel foil, rolling it to the required thickness. The roll smoothing unit is used to smooth the primary rolling unit to prevent deformation and affect the rolling quality. The secondary rolling unit is used to roll any protrusions that still exist after rolling the stainless steel foil at the primary rolling unit, ensuring that the stainless steel foil is smooth and flat.

[0007] Furthermore, the anti-wrinkle module includes a detection unit and a lubricating oil spraying unit. The detection unit is fixedly connected to the support frame and is located between the primary roll unit and the secondary roll unit. The lubricating oil spraying unit is fixedly connected to the support frame and is located between the unwinding guide roll and the primary roll unit.

[0008] The detection unit controls the flow rate of lubricating oil in the lubricating oil spraying unit. It detects the difference between the rolling linear speed of the stainless steel foil edge and the linear speed of the overall rolls in the primary rolling unit during rolling. If the rolling linear speed of the stainless steel foil edge is greater than the linear speed of the overall rolls in the primary rolling unit, the flow rate of the lubricating oil spraying unit directed towards the edge of the stainless steel foil is increased proportionally based on the difference. Conversely, if the rolling linear speed of the stainless steel foil edge is less than the linear speed of the overall rolls in the primary rolling unit, the flow rate of the lubricating oil spraying unit directed towards the edge of the stainless steel foil is decreased proportionally based on the difference. This ensures that the stainless steel foil maintains a uniform linear speed throughout the rolling process, preventing wrinkles or tensile deformation at the edge due to speed differences.

[0009] Furthermore, two detection units are provided, located on opposite sides of the stainless steel foil. The two detection units are symmetrical about the vertical axis of symmetry of the stainless steel foil. Each detection unit includes a rotating rod, an upper detection roller, a lower detection roller, a ventilation box, a rotating plate, and a linear switch. The ventilation box is fixedly connected to the support frame and is divided into an upper chamber and a lower chamber. The rotating rod is rotatably connected to the support frame and inserted into the upper chamber. A blade assembly is mounted on the rotating rod within the upper chamber, and the blade assembly is fixedly connected to the rotating rod. The rotating rod is connected to the primary upper roller via a belt, and the rotational speed of the rotating rod is the same as that of the primary upper roller. The upper detection roller is rotatably connected to the support frame and is located on the rotating rod. Directly below, the upper detection roller passes through the lower chamber and connects with the upper surface of the stainless steel foil. A blade assembly is installed on the upper detection roller in the lower chamber. The blade assembly and the upper detection roller are fixedly connected. The rotating plate and the ventilation box are rotatably connected. The upper half of the rotating plate is located in the upper chamber, and the lower half of the rotating plate is located in the lower chamber. The linear switch and the ventilation box are fixedly connected. The linear switch is used to control the flow rate of the lubricating oil spraying unit. One end of the linear switch abuts against the rotating plate. The linear switch is located on the side of the rotating plate facing the stainless steel foil. The rotating plate is located between the linear switch and the blade assembly. The lower detection roller is rotatably connected to the support frame. The lower detection roller connects with the lower surface of the stainless steel foil. The lower detection roller is located directly below the upper detection roller.

[0010] The distance between the upper and lower inspection rolls is equal to the distance between the primary upper and lower rolling rolls. During rolling, the primary upper rolling roll drives the rotating rod via a belt, and simultaneously, the stainless steel foil drives the upper and lower inspection rolls. As the rotating rod and upper inspection roll rotate, the two blade assemblies begin to rotate. After rotating, the two blade assemblies blow air onto the rotating plates in the upper and lower chambers, respectively. When the rotation speed of the rotating rod or upper inspection roll changes, the rotation speed of the corresponding blade assembly on the rotating rod or upper inspection roll also changes, thus changing the amount of air blown onto the rotating plates. When the rotation speed of the rotating rod is slower than the rotation speed of the upper inspection roll, the force on the rotating plates in the upper chamber is less than that on the rotating plates in the lower chamber. At this time, the rotation... When the plate rotates, the linear switch is pressed down, increasing the flow rate of the lubricating oil spraying unit pointing to the edge of the stainless steel foil rolling section until the rotation speed of the rotating rod equals that of the upper detection roller, at which point the rotating plate resets. When the rotation speed of the rotating rod is faster than that of the upper detection roller, the force on the part of the rotating plate in the upper chamber is greater than that on the part of the rotating plate in the lower chamber. At this time, the rotating plate rotates, opening the linear switch and decreasing the flow rate of the lubricating oil spraying unit pointing to the edge of the stainless steel foil rolling section until the rotation speed of the rotating rod equals that of the upper detection roller, at which point the rotating plate resets. This effectively avoids wrinkling or stretching deformation caused by insufficient or excessive lubrication at the edge of the stainless steel foil during the rolling process, resulting in speed differences between the stainless steel foil and the intermediate rolling section.

[0011] Furthermore, the lubricating oil spraying unit includes a fixing rod and a nozzle. There are two fixing rods, one above the stainless steel foil and the other below the stainless steel foil. There are multiple nozzles, which are fixedly connected to the two fixing rods and point towards the rolled part of the stainless steel foil.

[0012] All nozzles pointing towards the rolled edge of the stainless steel foil are electrically connected to a linear switch, which controls the flow rate of the nozzles. During the rolling process, if the linear switch is depressed, the flow rate of the nozzles pointing towards the rolled edge of the stainless steel foil increases; if the linear switch is opened, the flow rate of the nozzles pointing towards the rolled edge of the stainless steel foil decreases. This ensures that the stainless steel foil maintains a uniform linear velocity throughout the rolling process, preventing wrinkles or stretching deformation at the edges due to speed differences.

[0013] Furthermore, the primary rolling unit includes a primary rolling motor, a primary upper rolling roll, and a primary lower rolling roll. The primary rolling motor and the support frame are fixedly connected. The output shaft of the primary rolling motor and the support frame are rotatably connected. The primary upper rolling roll and the support frame are rotatably connected. The primary lower rolling roll and the support frame are rotatably connected. One end of the primary lower rolling roll passes through the support frame and is connected to the output shaft of the primary rolling motor via a belt drive.

[0014] During the rolling process, the output shaft of the primary roll motor drives the primary lower roll to rotate via belt transmission, while the primary upper roll is driven to rotate by the stainless steel foil during the conveying process. At this time, the primary lower roll and the primary upper roll work together to perform preliminary rolling processing on the stainless steel foil.

[0015] Furthermore, an upper annular chamber is provided inside the primary upper roll, and the central axis of the upper annular chamber coincides with that of the primary upper roll. The upper annular chamber is filled with magnetorheological fluid.

[0016] Magnetorheological fluids can rapidly change viscosity under the action of an external magnetic field, which facilitates the smoothing and repair of the surface of the primary rolls by the roll smoothing unit, and can be flexibly adjusted according to different rolling requirements.

[0017] Furthermore, a lower annular chamber is provided inside the primary lower roll, and the central axis of the lower annular chamber coincides with that of the primary lower roll. The lower annular chamber is filled with magnetorheological fluid.

[0018] Magnetorheological fluids can rapidly change viscosity under the action of an external magnetic field, which facilitates the smoothing and repair of the roll surface of the primary roll by the roll smoothing unit, and can be flexibly adjusted according to different rolling requirements.

[0019] Furthermore, the roll smoothing unit includes a base, a first coil, a second coil, a magnetic field shield, a fixing frame, an upper smoothing roll, and a lower smoothing roll. The base is housed within a support frame, and the base and support frame are fixedly connected. The first coil is fixedly connected to the base, and the second coil is fixedly connected to the base. The first coil is located between the primary roll unit and the unwinding guide roll, and the second coil is located between the detection unit and the primary roll unit. Two fixing frames are provided, both fixedly connected to the support frame. One fixing frame is located above the primary upper roll, and the upper smoothing roll and the lower smoothing roll... One fixed frame is rotatably connected, and there are multiple upper smoothing roller arrays. The surfaces of multiple upper smoothing rollers are tangent to the surfaces of the primary upper roll. Another fixed frame is located between the primary lower roll and the base. The lower smoothing rollers are rotatably connected to the other fixed frame. There are multiple lower smoothing roller arrays. The surfaces of multiple lower smoothing rollers are tangent to the surfaces of the primary lower roll. Two magnetic field shields are provided. Both magnetic field shields are fixedly connected to the support frame. One magnetic field shield covers multiple upper smoothing rollers and part of the upper annular cavity. The other magnetic field shield covers multiple lower smoothing rollers and part of the lower annular cavity.

[0020] The base is used for mounting and fixing the first and second coils, and the mounting bracket is used for mounting and fixing the upper and lower smoothing rolls. When the first and second coils are energized, a magnetic field is generated between them. The magnetorheological fluid in the upper and lower annular chambers within the magnetic field will become solid. By adjusting the magnitude of the current passing through the first and second coils, the hardness of the solid magnetorheological fluid can be changed, thereby adapting to the rolling requirements of different thicknesses. The magnetic field shield is used to shield the area where the upper and lower smoothing rolls are located. Part of the upper and lower annular chambers are also located in this area. The magnetorheological fluid in this area is in a liquid state or a solid state with low hardness because there is no magnetic field. During the rotation of the upper and lower rolls, when passing through this area, the upper and lower smoothing rolls will smooth the rolling surfaces of the upper and lower rolls to prevent deformation and thus affect the rolling quality.

[0021] Furthermore, the first and second coils have the same radius and number of turns, are parallel, have their central axes coincide, have the same direction of current, and are connected in series.

[0022] When setting the distance between the first coil and the second coil, it should be as close as possible to the radius of the first coil or the second coil to make the magnetic field generated between the first coil and the second coil more uniform, improve the solidification uniformity of the magnetorheological fluid, and ensure the stability and quality of rolling.

[0023] Furthermore, the secondary roll unit includes a secondary roll motor, a secondary upper roll, and a secondary lower roll. The secondary roll motor is fixedly connected to the support frame, the output shaft of the secondary roll motor is fixedly connected to one end of the secondary upper roll, the secondary upper roll is rotatably connected to the support frame, the secondary upper roll is located above the stainless steel foil, the secondary lower roll is rotatably connected to the support frame, the secondary lower roll abuts against the lower surface of the stainless steel foil, and the secondary lower roll is located directly above the secondary upper roll.

[0024] During the rolling process, the speed of the secondary roll motor is not equal to that of the secondary lower roll. This causes the secondary upper and lower rolls to exert an oblique squeezing force on the protruding parts of the stainless steel foil during the secondary rolling process. This force is used to flatten and eliminate the harder protruding parts of the stainless steel foil, thereby further improving the rolling quality.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. The anti-wrinkle module 6 of the present invention is used to prevent wrinkles from forming on the edge of the stainless steel foil during the rolling process, so as to ensure that the surface of the rolled product is smooth and flat. 2. The roll smoothing unit 8 of the present invention is used to smooth the primary roll unit 7 to prevent it from deforming and affecting the rolling quality; 3. The secondary roll unit 9 of the present invention is used to roll the protrusions that still exist after the stainless steel foil is rolled at the primary roll unit 7, so as to ensure that the stainless steel foil is smooth and flat after rolling.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: Figure 1 - Figure 8 As shown, the present invention provides a technical solution for a rolling equipment for producing stainless steel foil with an added lubrication function: like Figure 1 and Figure 2As shown, the rolling equipment includes a support frame 1, an unwinding roll 2, an unwinding guide roll 3, a take-up roll 4, a take-up guide roll 5, an anti-wrinkle module 6, a primary rolling unit 7, a roll smoothing unit 8, and a secondary rolling unit 9. The unwinding roll 2 is rotatably connected to the support frame 1, and is located at one end of the support frame 1. The take-up roll 4 is rotatably connected to the support frame 1, and is located at the other end of the support frame 1. The unwinding guide roll 3 is rotatably connected to the support frame 1, and is located between the unwinding roll 2 and the take-up roll 4. The take-up guide roll 5 is rotatably connected to the support frame 1, and is located between the unwinding guide roll 3 and the take-up roll 4. The anti-wrinkle module 6 is fixedly connected to the support frame 1, and is located on both sides of the primary rolling unit 7. Located between the unwinding guide roller 3 and the secondary roll unit 9, the primary roll unit 7 and the support frame 1 are rotatably connected. The primary roll unit 7 is located inside the roll smoothing unit 8. The roll smoothing unit 8 and the support frame 1 are fixedly connected. The roll smoothing unit 8 is located between the secondary roll unit 9 and the unwinding guide roller 3. The secondary roll unit 9 and the support frame 1 are rotatably connected. The secondary roll unit 9 is located between the unwinding guide roller 3 and the take-up guide roller 5. During rolling, the stainless steel foil passes sequentially below the unwinding roller 2, above the unwinding guide roller 3, through the anti-wrinkle module 6, the roll smoothing unit 8, the primary roll unit 7, the roll smoothing unit 8, the anti-wrinkle module 6, the secondary roll unit 9, below the take-up guide roller 5, and above the take-up roller 4.

[0030] Unwinding roll 2 is used for unwinding stainless steel foil, and winding roll 4 is used for winding stainless steel foil. Unwinding roll 2 and winding roll 4 are driven by a motor. Unwinding guide roll 3 and winding guide roll 5 provide a rolling path for stainless steel foil and provide a certain tension force for stainless steel foil. Anti-wrinkle module 6 is used to prevent wrinkles from forming on the edge of stainless steel foil during rolling, ensuring that the surface of the rolled product is smooth and flat. Primary rolling unit 7 is used to perform the initial rolling of stainless steel foil, rolling the stainless steel foil to the required thickness. Roll smoothing unit 8 is used to smooth primary rolling unit 7 to prevent deformation and affect rolling quality. Secondary rolling unit 9 is used to roll the protrusions that still exist after rolling the stainless steel foil at primary rolling unit 7, ensuring that the stainless steel foil is smooth and flat.

[0031] like Figure 2 As shown, the anti-wrinkle module 6 includes a detection unit 61 and a lubricating oil spraying unit 62. The detection unit 61 is fixedly connected to the support frame 1 and is located between the primary roll unit 7 and the secondary roll unit 9. The lubricating oil spraying unit 62 is fixedly connected to the support frame 1 and is located between the unwinding guide roll 3 and the primary roll unit 7.

[0032] The detection unit 61 can control the flow rate of lubricating oil in the lubricating oil spraying unit 62. The detection unit 61 is used to detect the difference between the rolling linear speed of the stainless steel foil edge and the linear speed of the overall roll at the primary roll unit 7 during the rolling process. If the rolling linear speed of the stainless steel foil edge is greater than the linear speed of the overall roll at the primary roll unit 7, the flow rate of the lubricating oil spraying unit 62 directed towards the edge of the stainless steel foil is increased proportionally according to the difference. If the rolling linear speed of the stainless steel foil edge is less than the linear speed of the overall roll at the primary roll unit 7, the flow rate of the lubricating oil spraying unit 62 directed towards the edge of the stainless steel foil is decreased proportionally according to the difference. This ensures that the stainless steel foil maintains a uniform linear speed during the rolling process and avoids wrinkles or stretching deformation of the edge due to speed differences.

[0033] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, two detection units 61 are provided, located on opposite sides of the stainless steel foil. The two detection units 61 are symmetrical about the vertical axis of symmetry of the stainless steel foil. Each detection unit 61 includes a rotating rod 63, an upper detection roller 64, a lower detection roller 65, a ventilation box 66, a rotating plate 67, and a linear switch 68. The ventilation box 66 is fixedly connected to the support frame 1 and is divided into an upper chamber 69 and a lower chamber 610. The rotating rod 63 is rotatably connected to the support frame 1 and is inserted into the upper chamber 69. The rotating rod 63 is rotatably connected to the ventilation box 66. A blade assembly 611 is provided on the rotating rod 63 inside the upper chamber 69. The blade assembly 611 is fixedly connected to the rotating rod 63. The rotating rod 63 is connected to the primary upper roller 72 via a belt, and the rotational speed of the rotating rod 63 is the same as the rotational speed of the primary upper roller 72. The upper detection roller 64 is rotatably connected to the support frame 1 and is located on the rotating rod 63. Directly below, the upper detection roller 64 passes through the lower chamber 610 and connects with the upper surface of the stainless steel foil. A blade assembly 611 is provided on the upper detection roller 64 inside the lower chamber 610. The blade assembly 611 and the upper detection roller 64 are fixedly connected. The rotating plate 67 and the ventilation box 66 are rotatably connected. The upper half of the rotating plate 67 is located in the upper chamber 69, and the lower half of the rotating plate 67 is located in the lower chamber 610. The linear switch 68 and the ventilation box 66 are fixedly connected. The linear switch 68 is used to control the flow rate of the lubricating oil spraying unit 62. One end of the linear switch 68 abuts against the rotating plate 67. The linear switch 68 is located on the side of the rotating plate 67 facing the stainless steel foil. The rotating plate 67 is located between the linear switch 68 and the blade assembly 611. The lower detection roller 65 is rotatably connected to the support frame 1. The lower detection roller 65 is connected with the lower surface of the stainless steel foil. The lower detection roller 65 is located directly below the upper detection roller 64.

[0034] The distance between the upper detection roll 64 and the lower detection roll 65 is equal to the distance between the primary upper roll 72 and the primary lower roll 73. When the rolling equipment is rolling, the primary upper roll 72 drives the rotating rod 63 to rotate via a belt. At the same time, the stainless steel foil drives the upper detection roll 64 and the lower detection roll 65 to rotate. As the rotating rod 63 and the upper detection roll 64 rotate, the two blade assemblies 611 begin to rotate. After the two blade assemblies 611 rotate, they will blow air onto the rotating plates 67 in the upper chamber 69 and the lower chamber 610 respectively. When the rotation speed of the rotating rod 63 or the upper detection roll 64 changes, the rotation speed of the corresponding blade assembly 611 on the rotating rod 63 or the upper detection roll 64 will also change, thereby changing the amount of air blown onto the rotating plates 67. When the rotation speed of the rotating rod 63 is slower than the rotation speed of the upper detection roll 64, the force on the rotating plates 67 in the upper chamber 69 is less than that in the lower chamber 610. Rotating plate 67 rotates, pressing down linear switch 68, increasing the flow rate of lubricating oil spraying unit 62 pointing to the edge rolling section of stainless steel foil until the rotation speed of rotating rod 63 equals the rotation speed of upper detection roller 64, at which point rotating plate 67 resets. When the rotation speed of rotating rod 63 is faster than that of upper detection roller 64, the force on part of rotating plate 67 in upper chamber 69 is greater than that on part of rotating plate 67 in lower chamber 610. At this time, rotating plate 67 rotates, opening linear switch 68, decreasing the flow rate of lubricating oil spraying unit 62 pointing to the edge rolling section of stainless steel foil until the rotation speed of rotating rod 63 equals that of upper detection roller 64, at which point rotating plate 67 resets. This effectively avoids wrinkling or stretching deformation caused by insufficient or excessive lubrication at the edge of stainless steel foil during rolling, resulting in speed differences between the stainless steel foil and the intermediate rolling section.

[0035] like Figure 8 As shown, the lubricating oil spraying unit 62 includes a fixing rod 612 and a nozzle 613. There are two fixing rods 612, one of which is located above the stainless steel foil and the other is located below the stainless steel foil. There are multiple nozzles 613, which are fixedly connected to the two fixing rods 612 and point towards the rolling part of the stainless steel foil.

[0036] All nozzles 613 pointing towards the edge of the stainless steel foil rolling section are electrically connected to a linear switch 68, which controls the flow rate of the nozzles 613. During the rolling process, if the linear switch 68 is pressed down, the flow rate of the nozzles 613 pointing towards the edge of the stainless steel foil rolling section increases; if the linear switch 68 is opened, the flow rate of the nozzles 613 pointing towards the edge of the stainless steel foil rolling section decreases. This ensures that the stainless steel foil maintains a uniform linear velocity throughout the rolling process, preventing wrinkles or tensile deformation at the edge due to speed differences.

[0037] like Figures 1 to 4As shown, the primary rolling unit 7 includes a primary rolling motor 71, a primary upper rolling roll 72, and a primary lower rolling roll 73. The primary rolling motor 71 is fixedly connected to the support frame 1. The output shaft of the primary rolling motor 71 is rotatably connected to the support frame 1. The primary upper rolling roll 72 is rotatably connected to the support frame 1. The primary lower rolling roll 73 is rotatably connected to the support frame 1. One end of the primary lower rolling roll 73 passes through the support frame 1 and is connected to the output shaft of the primary rolling motor 71 via a belt drive.

[0038] During the rolling process, the output shaft of the primary roll motor 71 drives the primary lower roll 73 to rotate via belt transmission, while the primary upper roll 72 is driven to rotate by the stainless steel foil during the conveying process. At this time, the primary lower roll 73 and the primary upper roll 72 work together to perform preliminary rolling processing on the stainless steel foil.

[0039] like Figure 8 As shown, an upper annular chamber 74 is provided inside the primary upper roll 72. The central axis of the upper annular chamber 74 coincides with that of the primary upper roll 72. The upper annular chamber 74 is filled with magnetorheological fluid.

[0040] Magnetorheological fluid can rapidly change its viscosity under the action of an external magnetic field, which facilitates the smoothing and repair of the surface of the primary roll 72 by the roll smoothing unit 8, and can be flexibly adjusted according to different rolling requirements.

[0041] like Figure 8 As shown, a lower annular chamber 75 is provided inside the primary lower roll 73. The central axis of the lower annular chamber 75 coincides with that of the primary lower roll 73. The lower annular chamber 75 is filled with magnetorheological fluid.

[0042] Magnetorheological fluid can rapidly change its viscosity under the action of an external magnetic field, which facilitates the smoothing and repair of the roll surface of the primary roll 73 by the roll smoothing unit 8, and can be flexibly adjusted according to different rolling requirements.

[0043] like Figure 3 , Figure 5 and Figure 8As shown, the roll smoothing unit 8 includes a base 81, a first coil 82, a second coil 83, a magnetic field shield 84, a fixing frame 85, an upper smoothing roll 86, and a lower smoothing roll 87. The base 81 is disposed inside the support frame 1 and is fixedly connected to the support frame 1. The first coil 82 is fixedly connected to the base 81, and the second coil 83 is fixedly connected to the base 81. The first coil 82 is located between the primary roll unit 7 and the unwinding guide roll 3, and the second coil 83 is located between the detection unit 61 and the primary roll unit 7. Two fixing frames 85 are provided and are fixedly connected to the support frame 1. One fixing frame 85 is located above the primary upper roll 72. The upper smoothing roll 86... 6 is rotatably connected to a fixed frame 85. There are multiple upper smoothing rollers 86 in an array. The surfaces of the multiple upper smoothing rollers 86 and the primary upper roller 72 are tangent. Another fixed frame 85 is located between the primary lower roller 73 and the base 81. The lower smoothing roller 87 is rotatably connected to another fixed frame 85. There are multiple lower smoothing rollers 87 in an array. The surfaces of the multiple lower smoothing rollers 87 and the primary lower roller 73 are tangent. Two magnetic field shields 84 are provided. Both magnetic field shields 84 are fixedly connected to the support frame 1. One magnetic field shield 84 covers multiple upper smoothing rollers 86 and part of the upper annular chamber 74. The other magnetic field shield 84 covers multiple lower smoothing rollers 87 and part of the lower annular chamber 75.

[0044] The base 81 is used for mounting and fixing the first coil 82 and the second coil 83, and the fixing bracket 85 is used for mounting and fixing the upper smoothing roller 86 and the lower smoothing roller 87. When the first coil 82 and the second coil 83 are energized, a magnetic field is generated between them. The magnetorheological fluid in the upper annular chamber 74 and the lower annular chamber 75 within the magnetic field will become solid. By adjusting the magnitude of the current passing through the first coil 82 and the second coil 83, the hardness of the solid magnetorheological fluid can be changed, thereby adapting to the rolling requirements of different thicknesses. (Magnetic field screen) The shielding element 84 is used to shield the area where the upper smoothing roll 86 and the lower smoothing roll 87 are located. Part of the upper annular chamber 74 and the lower annular chamber 75 are also located in this area. The magnetorheological fluid in this area is in a liquid state or a solid state with low hardness because there is no magnetic field. When the upper roll 72 and the lower roll 73 rotate through this area, the upper smoothing roll 86 and the lower smoothing roll 87 will smooth the rolling surface of the upper roll 72 and the lower roll 73 to prevent deformation and thus affect the rolling quality.

[0045] like Figure 5 and Figure 8 As shown, the first coil 82 and the second coil 83 have the same radius and number of turns, the first coil 82 and the second coil 83 are parallel, the central axes of the first coil 82 and the second coil 83 coincide, the currents on the first coil 82 and the second coil 83 are equidirectional, and the first coil 82 and the second coil 83 are connected in series.

[0046] When setting the distance between the first coil 82 and the second coil 83, it should be as close as possible to the radius of the first coil 82 or the second coil 83, so that the magnetic field generated between the first coil 82 and the second coil 83 is more uniform, thereby improving the solidification uniformity of the magnetorheological fluid and ensuring the stability and quality of rolling.

[0047] like Figure 3 and Figure 4 As shown, the secondary roll unit 9 includes a secondary roll motor 91, a secondary upper roll 92, and a secondary lower roll 93. The secondary roll motor 91 is fixedly connected to the support frame 1. The output shaft of the secondary roll motor 91 is fixedly connected to one end of the secondary upper roll 92. The secondary upper roll 92 is rotatably connected to the support frame 1 and is located above the stainless steel foil. The secondary lower roll 93 is rotatably connected to the support frame 1 and abuts against the lower surface of the stainless steel foil. The secondary lower roll 93 is located directly above the secondary upper roll 92.

[0048] During the rolling process, the rotation speed of the secondary roll motor 91 is not equal to that of the secondary lower roll 93. This causes the secondary upper roll 92 and the secondary lower roll 93 to exert oblique extrusion force on the protruding parts of the stainless steel foil when performing secondary rolling on the stainless steel foil. This force is used to flatten the harder protruding parts of the stainless steel foil and further improve the rolling quality.

[0049] The working principle of this invention is as follows: Unwinding roller 2 is used for unwinding stainless steel foil, and winding roller 4 is used for winding stainless steel foil. Unwinding roller 2 and winding roller 4 are driven by a motor. Unwinding guide roller 3 and winding guide roller 5 provide a rolling path for stainless steel foil and provide a certain tension force for stainless steel foil. Anti-wrinkle module 6 is used to prevent wrinkles from forming on the edge of stainless steel foil during the rolling process, ensuring that the surface of the rolled product is smooth and flat. Primary rolling unit 7 is used to perform the initial rolling of stainless steel foil to roll it to the required thickness. Roll smoothing unit 8 is used to smooth primary rolling unit 7 to prevent deformation and affect rolling quality. Secondary rolling unit 9 is used to roll any protrusions that still exist after rolling of stainless steel foil at primary rolling unit 7, ensuring that stainless steel foil is smooth and flat.

[0050] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
