Description

Technical Field

[0001] This invention relates to the field of battery separator slitting technology, and in particular to a flattening roller adjustment device for a small-width battery separator slitting machine. Background Technology

[0002] Battery separators are a layer of membrane material placed between the positive and negative electrodes of a battery. They are a crucial component, directly impacting battery safety and cost. Their main functions are to isolate the positive and negative electrodes, preventing electrons from freely passing through while allowing ions in the electrolyte to freely pass between them. During slitting, depending on the specific requirements, separator rolls with a width exceeding 1000mm need to be cut into rolls with widths ranging from 40mm to 300mm. Before entering the slitting rollers, the separator surface needs to be smoothed by flattening rollers to eliminate wrinkles. The installation angle and the flattening roller's own angle directly affect the flattening effect of the separator, further impacting the subsequent slitting accuracy and quality. Current flattening roller adjustment structures are complex and lack flexibility, failing to allow for timely adjustments based on the actual condition of the separator.

[0003] Therefore, it is necessary to develop a flattening roller adjustment device and a slitting machine for a small-width battery separator slitting machine to overcome the above-mentioned defects. Summary of the Invention

[0029] Embodiment 1

[0030] Refer Figures 1 to 3 As shown, this embodiment discloses a specific implementation of a flattening roller adjustment device for a narrow-width battery separator slitter (hereinafter referred to as the "adjustment device").

[0031] The flattening roller adjustment device for a narrow-width battery separator slitter, refer Figures 1 to 3 As shown, it includes a flattening roller 1 with a curvature and a swing block 2 provided at the end of the flattening roller 1. The arc height of the flattening roller 1 is 5 mm - 10 mm, preferably 8 mm or 10 mm. The highest point on the surface of the flattening roller 1 is located in the middle of the flattening roller 1. The arc height refers to the maximum vertical height h between the highest point of the flattening roller 1 and the connecting line of the endpoints of the flattening roller 1. For specific reference Figure 4 An angle adjustment rod 3 is also provided at the bottom of the swing block 2, and an angle adjustment component is provided at one end of the angle adjustment rod 3. The angle adjustment component includes a worm gear 4 and a turbine 5. The angle adjustment rod 3 passes through and is fixedly connected to the turbine 5. When the worm gear 4 rotates, it drives the turbine 5 to rotate, which in turn drives the angle adjustment rod 3 to rotate, causing the swing block 2 to swing, thereby adjusting the installation angle of the flattening roller 1.

[0032] See Figure 1 and Figure 2 Since the installation angle and its own angle of the flattening roller directly affect the flattening effect of the diaphragm, and further affect the subsequent slitting accuracy and slitting quality, in addition to flexibly adjusting the installation angle of the flattening roller 1 through the worm gear 4 and the turbine 5, it is also necessary to adjust the angle of the flattening roller 1 itself. The specific adjustment structure is as follows: a sleeve 11 is provided at the end of the flattening roller 1. The sleeve 11 is fixed to the swing block 2 by screws 12. A positioning hole 13 is provided in the sleeve 11. When it is necessary to adjust the angle of the flattening roller 1 itself, that is, to adjust the arc position of the flattening roller 1, the screws 12 are loosened, and a wrench is inserted into the positioning block 13 and rotated to make the flattening roller 1 rotate to a suitable position. Then, the screws 12 are tightened to achieve the positioning of the flattening roller 1 at a suitable angle.

[0033] See Figure 2 To facilitate adjustment of the installation angle of the flattening roller 1, a manual wheel 6 is provided at the end of the worm gear 4. By rotating the manual wheel 6, the worm gear 4 is driven to rotate, thereby driving the turbine 5 to rotate, ultimately adjusting the installation angle of the flattening roller 1. Once the installation angle is adjusted to the correct position, the locking handle 7 is tightened to lock the connection between the manual wheel 6 and the worm gear, thus fixing the installation angle of the flattening roller 1. To facilitate the characterization of the installation angle of the flattening roller 1, a pointer 31 is provided at the end of the angle adjustment rod 3. A scale 32 is provided on the frame of the slitting machine. The pointer 31 cooperates with the scale 32. When the angle adjustment rod 3 is driven to rotate by the worm gear 4 and the turbine 5, the angle adjustment rod 3 causes the pointer 31 at its end to deflect. The angle of deflection is read through the scale 32, making it convenient for the adjustment personnel to determine the installation angle of the flattening roller 1.

[0034] The installation angle range of the flattening roller 1, that is, the maximum rotation angle of the pointer 31, is ±10° to ±45°, preferably ±30°. The principle of the maximum rotation angle is as follows: a first stop 42 and a second stop 43 are respectively set on both sides of the spiral tooth 41 of the worm 4. The maximum rotation angle of the flattening roller 1 is determined by the length of the spiral tooth 41. The maximum rotation angle of the flattening roller 1 can also be limited by adjusting the distance between the first stop 42 and the second stop 43. In addition, the first stop 42 and the second stop 43 are fixed on the bracket of the slitting machine, which plays the role of fixing and stabilizing the angle adjustment component.

[0035] While achieving flexible adjustment of the installation angle and arc position of the flattening roller 1, it is essential that the optimal position of the flattening roller 1 during installation is that the highest point of its arc surface coincides with the center line of the battery separator. The higher the degree of coincidence, the better the flattening effect of the separator. Given that the current structure for centering adjustment of the flattening roller 1 is too complex, the centering adjustment technology of the flattening roller 1 provided in this embodiment is as follows: The swing block 2 includes a first swing block 21 and a second swing block 22. The angle adjustment rod 3 is sandwiched between the first swing block 21 and the second swing block 22. The centering of the flattening roller 1 is adjusted by the position of the swing block 2 installed on the angle adjustment rod 3. The swing block 2 composed of the first swing block 21 and the second swing block 22 can not only adjust the installation angle of the flattening roller 1, but also adjust the horizontal displacement of the flattening roller 1 by adjusting the installation position of the swing block 2, thereby adjusting the centering of the flattening roller 1. The simple structure of the swing block 2 allows for the adjustment of the installation angle and centering of the flattening roller 1, ensuring that the highest point of the arc surface of the flattening roller 1 coincides with the center line of the battery separator.

[0036] This embodiment allows for the adjustment of the installation angle, arc angle, and centering of the flattening roller 1. The adjustment structure is simple and convenient, with high adjustment efficiency, and saves manufacturing costs.

[0037] Example 2

[0038] The small-width battery separator slitting machine includes the flattening roller adjustment device for the small-width battery separator slitting machine as described in Example 1.

[0039] To cut battery separator rolls with a width of 1000mm-1500mm into smaller separator rolls with a width of 40mm-300mm, a flattening roller is needed to remove wrinkles from the separator surface before it enters the cutting roller, in order to ensure the cutting quality and accuracy. To ensure that the separator is flattened in place, the installation angle, its own arc angle and centering of the flattening roller 1 need to be adjusted by an adjustment device.

[0040] The small-width battery separator slitting machine disclosed in this embodiment has the same technical solution as that in Embodiment 1. Please refer to Embodiment 1 for details, which will not be repeated here.
