Description

Technical Field

[0001] This invention relates to the field of aluminum foil rolling processing, specifically to a self-narrowing and rolling current collector plate-shaped aluminum foil circulating rolling device and its rolling method. Background Technology

[0002] Current collector aluminum foil, typically in thin sheet form, is a key component of electrochemical energy storage devices such as batteries. As a current collector, it forms a bridge between the battery's positive electrode and the external circuit, collecting the current generated by the electrode and transmitting it to the external circuit, ensuring the battery's normal charging and discharging functions. In actual production, the aluminum foil material is repeatedly rolled using a rolling mill to significantly optimize key indicators such as thickness, strength, and conductivity, resulting in a product with superior performance.

[0003] In existing rolling equipment, aluminum foil raw material is unwound by an unwinding mechanism and enters between a pair of rollers through guide rollers. The rollers are driven by a motor to rotate and apply pressure to the aluminum foil to reduce its thickness. Due to the plastic deformation characteristics of aluminum foil material, the aluminum foil becomes thinner under the extrusion of the rollers, and a "self-narrowing" phenomenon occurs in the width direction. Subsequently, the rolled aluminum foil is conveyed to the winding mechanism by guide rollers to be wound into finished product.

[0004] However, in current aluminum foil rolling processes, hydraulic mechanisms typically operate on liftable plates at both ends of the roll shaft to transfer pressure to the roll. This design tends to concentrate pressure at both ends of the roll, inevitably resulting in some difference in pressure on the aluminum foil material between the ends and the middle of the roll. Since the quality requirements for the product are usually very high during aluminum foil rolling, especially for indicators such as thickness uniformity, even small pressure differences can affect the quality of the aluminum foil to some extent, such as causing uneven mechanical and electrical properties, which in turn affects its performance in subsequent use. Therefore, there is still room for improvement in the processing accuracy of existing rolling equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a self-narrowing and rolling current collector plate aluminum foil circulating rolling apparatus and rolling method thereof, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-narrowing, rolling current collector plate aluminum foil circulating rolling apparatus, including a frame, and further comprising:

[0008] The upper roller is movably mounted on the frame, while the lower roller is rotatably mounted on the frame. Both ends of the upper roller are equipped with roller shafts, and the upper roller has a cavity inside. The two ends of the roller shafts are connected and communicate with the cavity.

[0009] The machine frame has a horizontal frame and a horizontal shaft on the horizontal frame. The horizontal frame can be driven up and down by two sets of lifting mechanisms on the machine frame so that the upper roller moves away from or closer to the lower roller. The horizontal shaft passes through the roller shaft and the upper roller, and a gap is reserved between the outer wall of the horizontal shaft and the inner wall of the roller shaft. The cavity is provided with multiple pulleys that are equidistantly distributed along the axial direction of the upper roller and abut against the inner wall of the upper roller. Each of the multiple pulleys is connected to the horizontal shaft through a set of driven mechanisms, and the horizontal shaft is provided with two sets of active mechanisms that cooperate with the multiple sets of driven mechanisms.

[0010] The two sets of power mechanisms mounted on the crossbeam can apply axial thrust along the horizontal axis to the two sets of driving mechanisms during the rolling process, and cause the driven mechanism to act on the inner wall of the upper roll through the pulley, applying a downward pressure perpendicular to the axial direction of the upper roll.

[0011] As a further embodiment of the present invention: the cross frame is further provided with a drive assembly connected to the roller shaft, the drive assembly includes a guide plate disposed at the bottom of the cross frame and a telescopic plate slidably fitted with the guide plate, the roller shaft is rotatably connected to the telescopic plate, and a limiting structure is provided between the guide plate and the telescopic plate;

[0012] The drive assembly also includes a drive motor mounted on the telescopic plate, and the output shaft of the drive motor is connected to the roller shaft via a bevel gear set.

[0013] As a further embodiment of the present invention: the limiting structure includes a limiting plate that is slidably fitted into the side of the guide plate, and a second hydraulic cylinder is rotatably mounted on the crossbeam, the movable end of the second hydraulic cylinder being rotatably connected to the limiting plate;

[0014] The telescopic plate has a first protruding block on its side, and the limiting plate has a second protruding block on its side facing the telescopic plate.

[0015] As a further embodiment of the present invention: the driven mechanism includes a guide block disposed on the horizontal axis and a driven block slidably fitted with the guide block, and the pulley is installed at the end of the driven block away from the horizontal axis.

[0016] As a further embodiment of the present invention: the active mechanism includes a sliding sleeve sleeved on the horizontal shaft and capable of moving along the axial direction of the horizontal shaft, and two horizontal arms disposed on the sliding sleeve. A sliding clearance structure is provided between the horizontal arms and the driven block, and the length direction of the horizontal arms is parallel to the axial direction of the horizontal shaft.

[0017] As a further embodiment of the present invention: the outer wall of the horizontal shaft is formed with a guide protrusion, and the inner wall of the sliding sleeve is provided with a strip groove, the strip groove being adapted to the guide protrusion, and both being parallel to the central axis of the horizontal shaft and the sliding sleeve.

[0018] As a further embodiment of the present invention: the sliding clearance structure includes a plurality of first triangular blocks disposed on the cross arm, the plurality of first triangular blocks being equidistantly distributed along the length direction of the cross arm, a second triangular block being disposed on the side of the driven block, the inclined surfaces of the first triangular block and the second triangular block being slidably attached, and when the first triangular block applies pressure to the second triangular block, it can cause the driven block to apply pressure to the inner wall of the upper roller through the pulley.

[0019] As a further embodiment of the present invention: the cross frame is provided with a sliding groove, the active mechanism includes a slider that is slidably fitted in the sliding groove, a guide arm disposed at the bottom of the slider, and a telescopic arm that is slidably fitted with the guide arm, and a third hydraulic cylinder is also rotatably mounted on the cross frame, the movable end of the third hydraulic cylinder being rotatably connected to the slider.

[0020] As a further embodiment of the present invention: a kit is slidably sleeved on the roller shaft, the telescopic arm is rotatably connected to the kit, and the kit is fixedly connected with a plurality of force transmission rods distributed equidistantly along the circumference. The force transmission rods extend into the interior of the upper roller and are slidably connected to the upper roller. A ball is provided at the end of the force transmission rod away from the kit, and the ball abuts against a disc body disposed on the sliding sleeve facing the end of the force transmission rod.

[0021] A method for cyclically rolling current collector plate-shaped aluminum foil, using the aforementioned rolling apparatus, includes the following steps:

[0022] Step 1: The aluminum foil raw material is pulled through the space between the upper and lower rollers;

[0023] Step 2: The lifting mechanism drives the crossbeam to lower the upper roller until the upper and lower surfaces of the aluminum foil material contact the outer walls of the upper and lower rollers, respectively.

[0024] Step 3: The limiting structure releases its limiting effect on the telescopic plate;

[0025] Step four: The power mechanism operates, applying an axial thrust along the horizontal axis to the driving mechanism. The driving mechanism cooperates with the driven mechanism to generate downward pressure on the upper roller through multiple pulleys.

[0026] Step 5: The aluminum foil raw material is pulled, the upper and lower rollers rotate, the rolled aluminum foil is wound up, and finally it undergoes a cycle rolling process.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This application provides a chamber in the upper roller, with multiple pulleys arranged equidistantly within the chamber. These pulleys abut against the inner wall of the upper roller. During the rolling process, the power mechanism sequentially applies downward pressure to the upper roller via the active and driven mechanisms, utilizing the multiple pulleys. This results in a more uniform distribution of pressure on the aluminum foil material across the width of the aluminum foil, effectively improving the uniformity of the mechanical and electrical properties of the aluminum foil and enhancing its performance in subsequent applications.

[0029] Secondly, in this application, multiple pulleys are located inside the upper roller and are arranged at equal intervals along the circumference of the upper roller. This allows for the application of a uniformly distributed downward pressure along the axial direction to the upper roller. Compared to the method of arranging multiple pressure rollers at equal intervals along the axial direction on the outside of the pressure roller, this avoids damage to the pressure roller caused by the pressure rollers, which could lead to scratches or abrasions on the aluminum foil surface, affecting the surface smoothness of the aluminum foil, increasing the surface roughness of the aluminum foil, and affecting subsequent processing performance and applications.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0046] Furthermore, elements in this invention are referred to as being "disposed on" or "located on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] Please see Figures 1-14 In this embodiment of the invention, the self-narrowing and rolling current collector plate-shaped aluminum foil circulating rolling device includes a frame 1, and further includes:

[0048] Upper roller 2 and lower roller 3 are provided. Upper roller 2 is movably mounted on frame 1, and lower roller 3 is rotatably mounted on frame 1. Roller shafts 7 are provided at both ends of upper roller 2. A cavity is provided inside upper roller 2. Both ends of roller shaft 7 are connected and communicate with the cavity.

[0049] The crossbeam 5 is mounted on the frame 1 and the cross shaft 10 is mounted on the crossbeam 5. The crossbeam 5 can be driven up and down by two sets of lifting mechanisms on the frame 1 so that the upper roller 2 moves away from or closer to the lower roller 3. The cross shaft 10 passes through the roller shaft 7 and the upper roller 2, and a gap is reserved between the outer wall of the cross shaft 10 and the inner wall of the roller shaft 7. The cavity is provided with multiple pulleys 25 that are equidistantly distributed along the axial direction of the upper roller 2 and abut against the inner wall of the upper roller 2. Each of the multiple pulleys 25 is connected to the cross shaft 10 through a set of driven mechanisms, and the cross shaft 10 is provided with two sets of active mechanisms that cooperate with the multiple sets of driven mechanisms.

[0050] The two sets of power mechanisms installed on the cross frame 5 can apply axial thrust along the horizontal axis 10 to the two sets of active mechanisms during the rolling process, and cause the driven mechanism to act on the inner wall of the upper roll 2 through the pulley 25, applying a downward pressure perpendicular to the axial direction of the upper roll 2 to the upper roll 2.

[0051] It should be noted that during rolling, the aluminum foil material passes between the upper roller 2 and the lower roller 3, and the lifting mechanism drives the crossbeam 5 to lower the upper roller 2 until the upper and lower surfaces of the aluminum foil material contact the outer walls of the upper roller 2 and the lower roller 3 respectively.

[0052] Subsequently, the power mechanism operates, applying an axial thrust along the transverse axis 10 to the active mechanism. The active mechanism cooperates with the driven mechanism, transmitting the force to the driven mechanism. Thus, the driven mechanism generates downward pressure through the pulley 25, thereby enabling the upper roller 2 to apply a certain downward pressure to the aluminum foil raw material, achieving the purpose of rolling.

[0053] Furthermore, this application provides a chamber in the upper roller 2, and a plurality of equidistantly arranged pulleys 25 are densely packed within the chamber, with the pulleys 25 abutting against the inner wall of the upper roller 2. During the rolling process, the power mechanism applies downward pressure to the upper roller 2 through the active mechanism and the driven mechanism in sequence, using the plurality of pulleys 25. This makes the pressure of the upper roller 2 on the aluminum foil material more uniformly distributed in the width direction of the aluminum foil, which can effectively improve the uniformity of the mechanical and electrical properties of the aluminum foil and enhance the performance of the aluminum foil in subsequent use.

[0054] Please refer to it again. Figure 7The lifting mechanism includes two guide shafts 4 disposed on the inner side of the frame 1 and a first hydraulic cylinder 6 disposed on the frame 1. The cross frame 5 is slidably connected to the guide shafts 4. The movable end of the first hydraulic cylinder 6 is fixed to the cross frame 5. Before the rolling starts and after the rolling ends, the first hydraulic cylinder 6 can drive the cross frame 5 to descend and rise respectively, thereby facilitating the adjustment of the height of the upper roller 2.

[0055] Please refer to it again. Figure 5 , Figure 8 as well as Figure 11 The cross frame 5 is also provided with a drive assembly connected to the roller shaft 7. The drive assembly includes a guide plate 11 disposed at the bottom of the cross frame 5 and a telescopic plate 12 slidably fitted with the guide plate 11. The roller shaft 7 is rotatably connected to the telescopic plate 12, and a limiting structure is provided between the guide plate 11 and the telescopic plate 12. The drive assembly also includes a drive motor 9 mounted on the telescopic plate 12. The output shaft of the drive motor 9 is connected to the roller shaft 7 through a bevel gear set 8.

[0056] To elaborate, the bevel gear set 8 includes a first bevel gear disposed at the end of the output shaft of the drive motor 9 and a second bevel gear disposed on the roller shaft 7 and meshing with the first bevel gear;

[0057] Secondly, as shown in the attached figure, the drive assembly is provided in two sets, which can distribute the torque more evenly and avoid the problem of uneven torque caused by single-end drive, thereby reducing the shaking or vibration of the upper roller 2 during rotation, making the pressure roller run more smoothly and improving the stability of the rolling process.

[0058] During the rolling process, it is often necessary to control the rotation of the two rollers (i.e., the upper roller 2 and the lower roller 3). This is because aluminum foil rolling has high requirements for thickness uniformity and surface quality. Precise speed control is needed to ensure the rolling effect.

[0059] Specifically, for the rotation of the upper roller 2, the output shaft of the drive motor 9 can drive the roller shaft 7 to rotate through the bevel gear set 8, thereby realizing the rotation of the upper roller 2; for the rotation of the lower roller 3, a motor (not labeled in the figure) whose output end is connected to the rotation shaft of the lower roller 3 is installed on the side of the frame 1.

[0060] It should also be noted that the telescopic plate 12 is provided with a mounting base on the side facing the drive motor 9, and the drive motor 9 is mounted on the mounting base. The guide plate 11 has an opening on its side with a height greater than that of the mounting base. This is for the same purpose as the gap between the outer wall of the horizontal shaft 10 and the inner wall of the roller shaft 7, in order to ensure that the force can be transmitted normally.

[0061] The limiting structure includes a limiting plate 13 that is slidably fitted into the side of the guide plate 11. A second hydraulic cylinder 14 is rotatably mounted on the cross frame 5. The movable end of the second hydraulic cylinder 14 is rotatably connected to the limiting plate 13. A first protruding block 1201 is provided on the side of the telescopic plate 12. A second protruding block 1301 is provided on the side of the limiting plate 13 facing the telescopic plate 12.

[0062] With attachment Figure 7 Taking the state shown as an example, before the upper roller 2 descends to contact the aluminum foil material, the second protruding block 1301 is located below the first protruding block 1201. Thus, the limiting plate 13 can limit the telescopic plate 12. After the upper roller 2 completes its descent, that is, after the upper and lower surfaces of the aluminum foil material contact the outer walls of the upper roller 2 and the lower roller 3 respectively, the movable end of the second hydraulic cylinder 14 extends, driving the limiting plate 13 to slide downward relative to the guide plate 11. Thus, the second protruding block 1301 separates from the first protruding block 1201, so as to realize the normal transmission of the downward pressure required for subsequent rolling.

[0063] Please refer to it again. Figure 9 , Figure 12 , Figure 13 as well as Figure 14 The driven mechanism includes a guide block 23 disposed on the horizontal shaft 10 and a driven block 24 slidably fitted with the guide block 23. The pulley 25 is mounted on the end of the driven block 24 away from the horizontal shaft 10. The driving mechanism includes a sliding sleeve 20 sleeved on the horizontal shaft 10 and movable along the axial direction of the horizontal shaft 10, and two horizontal arms 22 disposed on the sliding sleeve 20. A sliding clearance structure is provided between the horizontal arms 22 and the driven block 24, and the length direction of the horizontal arms 22 is parallel to the axial direction of the horizontal shaft 10. A guide protrusion 1001 is formed on the outer wall of the horizontal shaft 10, and a strip groove 2001 is provided on the inner wall of the sliding sleeve 20. The strip groove 2001 is adapted to the guide protrusion 1001, and both are parallel to the central axis of the horizontal shaft 10 and the sliding sleeve 20.

[0064] The guide protrusion 1001 and the strip groove 2001 are designed to guide the sliding sleeve 20, ensuring that the sliding sleeve 20 can only move linearly along the axial direction of the horizontal axis 10. That is, when the power mechanism is working, it will apply a thrust along the axial direction of the horizontal axis 10 to the sliding sleeve 20. The horizontal arm 22 can use the sliding clearance structure to allow the pulley 25 to apply pressure perpendicular to the axial direction of the upper roller 2 to the inner wall of the upper roller 2.

[0065] The sliding clearance structure includes a plurality of first triangular blocks 26 disposed on the cross arm 22. The plurality of first triangular blocks 26 are equidistantly distributed along the length direction of the cross arm 22. A second triangular block 27 is disposed on the side of the driven block 24. The inclined surfaces of the first triangular block 26 and the second triangular block 27 slide against each other. When the first triangular block 26 applies pressure to the second triangular block 27, it can cause the driven block 24 to apply pressure to the inner wall of the upper roller 2 through the pulley 25.

[0066] Furthermore, when the power mechanism is working, it applies a thrust along the axial direction of the horizontal axis 10 to the sliding sleeve 20. As a result, the two sliding sleeves 20 on the horizontal axis 10 tend to slide closer to each other. Correspondingly, the first triangular block 26 applies pressure to the second triangular block 27. Under the action of the inclined surfaces of the two, the second triangular block 27 has a downward driving force, which causes the pulley 25 to apply downward pressure to the inner wall of the upper roller 2 and transmit it to the aluminum foil material.

[0067] Please refer to it again. Figure 5 , Figure 8 , Figure 9 as well as Figure 10 The cross frame 5 is provided with a sliding groove 501. The active mechanism includes a slider 16 that is slidably fitted in the sliding groove 501, a guide arm 17 disposed at the bottom of the slider 16, and a telescopic arm 18 that is slidably fitted with the guide arm 17. A third hydraulic cylinder 15 is also rotatably mounted on the cross frame 5. The movable end of the third hydraulic cylinder 15 is rotatably connected to the slider 16. A kit 701 is slidably fitted on the roller shaft 7. The telescopic arm 18 is rotatably connected to the kit 701. The kit 701 is fixedly connected with a plurality of force transmission rods 19 that are equidistantly distributed along the circumference. The force transmission rods 19 extend into the interior of the upper roller 2 and are slidably connected to the upper roller 2. A ball is provided at the end of the force transmission rod 19 away from the kit 701. The ball abuts against the disc 21 disposed on the sliding sleeve 20 facing the end of the force transmission rod 19.

[0068] During rolling, the third hydraulic cylinder 15 provides power, causing the slider 16 to tend to slide towards the middle part of the crossbeam 5 within the groove 501. Then, the slider 16 transmits force through the guide arm 17, the telescopic arm 18, and the kit 701, causing the force transmission rod 19 to apply a pushing force to the disc 21. Finally, the first triangular block 26 and the second triangular block 27 are used to make the pulley 25 generate the downward pressure required for rolling on the upper roller 2.

[0069] In this application, multiple pulleys 25 are located inside the upper roller 2 and are equidistantly arranged along the circumference of the upper roller 2, which can apply a uniformly distributed downward pressure along the axial direction to the upper roller 2. If multiple pressure rollers are arranged equidistantly along the circumference of the upper roller 2 above the upper roller 2, although this method can also achieve a uniform distribution of downward pressure, as the pressure rollers apply pressure to the surface of the upper roller 2, as the rolling time increases, the pressure rollers may cause damage to the outer wall of the upper roller 2. Consequently, in subsequent processing, the upper roller 2 may leave scratches or abrasions on the surface of the aluminum foil, affecting the surface smoothness of the aluminum foil and increasing the surface roughness of the aluminum foil, which affects the subsequent processing performance and application (for aluminum foil that needs to be coated or plated, excessive roughness will cause uneven coating or plating, reducing product quality).

[0070] As another embodiment of the present invention, a method for cyclic rolling of current collector plate-shaped aluminum foil is also proposed, using the aforementioned rolling apparatus, including the following steps:

[0071] Step 1: The aluminum foil raw material is pulled through the space between the upper roller 2 and the lower roller 3;

[0072] Step 2: The lifting mechanism drives the cross frame 5 to lower the upper roller 2 until the upper and lower surfaces of the aluminum foil material contact the outer walls of the upper roller 2 and the lower roller 3 respectively.

[0073] Step 3: The limiting structure releases the limiting state on the telescopic plate 12;

[0074] Step four: The power mechanism operates, applying an axial thrust along the horizontal axis 10 to the driving mechanism. The driving mechanism cooperates with the driven mechanism to generate downward pressure on the upper roller 2 through multiple pulleys 25.

[0075] Step 5: The aluminum foil raw material is pulled, the upper roller 2 and the lower roller 3 rotate, the rolled aluminum foil is wound up, and finally it is subjected to a cycle rolling process.

[0076] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0077] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
