Description

Technical Field

[0001] The present application relates to the technical field of lithium-ion batteries, and in particular to a material roll winding device that is convenient for cutting. Background Art

[0002] The lithium battery coating process involves applying active materials to the surfaces of the positive and negative electrode materials of lithium batteries to enhance the battery's capacity and performance to meet specific usage requirements. The lithium battery separator market primarily ships wet-process separators. Conventional cutters produce a tail of material during automatic cutting on the coating machine's reel. This tail of material can cause tens or even dozens of meters of finished product on the reel core to become waste. This led to the development of a cutting method that reduces the tail of material.

[0003] There are two main methods for cutting off scraps: one uses a brush attached to a regular cutter. After the cutter cuts the material, the brush brushes the scraps onto the paper core. This method is simple, but less effective. The scraps often don't stick together properly, affecting product quality, and it's not suitable for high-speed cutting. Another method uses a storage rack for zero-speed cutting, which is more effective. However, the racks are bulky and expensive to produce. Lithium battery separators rupture at high temperatures, causing short circuits and wrinkling. The roll diameter cannot be too large, and the amount of scraps removed at a time cannot be too large. Therefore, these two methods are not very suitable.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Utility Model Content

[0005] The purpose of the present application is to adjust the material roll to a position suitable for cutting with a cutter, while achieving cutting of the material roll with less tail material.

[0006] The above technical purpose of the present application is achieved through the following technical solutions: a material roll winding device that is convenient for cutting, including a mounting frame, a first rotating disk is provided on the mounting frame, a first material roll is provided on the first rotating disk, a second rotating disk is provided on the first rotating disk for coaxial rotation, a second material roll is provided on the second rotating disk, the second rotating disk can rotate synchronously with the first rotating disk, or the second rotating disk can rotate relative to the first rotating disk to adjust the straight-line distance between the first material roll and the second material roll.

[0007] By adopting this technical solution, the linear distance between the first and second rolls can be reduced, reducing the amount of scrap after cutting and improving material utilization. The synchronous or relative rotation of the two rotating disks adjusts the cutting position and angle of the strip between the two rolls, facilitating the cutting of the strip by the cutting assembly and improving cutting efficiency. Combined with the sophisticated design of the pressing and cutting assemblies, this effectively improves cutting quality and product yield, adapting to the needs of high-speed cutting and resolving the problem of poor scrap handling in traditional cutting methods.

[0008] Optionally, it further includes a base plate, on which a first linear guide rail is provided, and the mounting frame is provided on the first linear guide rail, and the mounting frame slides relative to the base plate.

[0009] By adopting this technical solution, the mounting frame slides relative to the base plate, allowing the device to be flexibly adjusted during operation to adapt to different work scenarios and operational requirements. This sliding design increases the device's adjustability, facilitating more precise winding and cutting of rolls. It also allows operators to operate and monitor the device from various angles and positions, improving work convenience and efficiency.

[0010] Optionally, the base plate is provided with an adjusting screw for adjusting the height between the base plate and the ground.

[0011] By adopting this technical solution, the adjustment screws allow the base plate to adapt to uneven surfaces, ensuring the device remains stable during operation and improving operational stability. The height of the device can be adjusted to suit the operator's height and operating habits, providing a more comfortable and efficient operating experience. The appropriate height helps reduce cutting errors caused by tilting or instability of the device, thereby improving cutting accuracy and quality.

[0012] Optionally, a pressing assembly is further included, which includes a second linear guide rail arranged on the mounting frame, and a pressing roller is provided on the second linear guide rail, and the pressing roller is driven by the second linear guide rail to move toward or away from the second material roll.

[0013] By adopting this technical solution, the movable pressure roller design can flexibly adjust the pressure on the roll according to different roll conditions and cutting requirements, ensuring the stability of the roll during the cutting process. This effectively prevents the roll from shifting or loosening during cutting, ensuring cutting precision and accuracy. This helps achieve more uniform cutting results and improve product consistency and quality.

[0014] Optionally, a cutting assembly is further included, which includes a third linear guide rail arranged on the mounting frame, a first cylinder mounting plate is provided on the third linear guide rail, a first driving cylinder is provided on the first cylinder mounting plate, and a first cutting knife is provided on the first driving cylinder.

[0015] By employing this technical solution, the third linear guide rail enables the first cutter to be precisely moved to the desired cutting position, improving cutting accuracy and precision. The combination of the first cylinder mounting plate and the first drive cylinder provides stable and powerful drive for the first cutter, ensuring smooth cutting. This modular design facilitates maintenance and replacement of cutting components, reducing equipment maintenance costs and downtime.

[0016] Optionally, the cutting assembly further includes a fourth linear guide rail provided on the mounting frame, a second cylinder mounting plate is provided on the fourth linear guide rail, a second driving cylinder is provided on the second cylinder mounting plate, and a second cutting knife is provided on the second driving cylinder.

[0017] By adopting this technical solution and adding a second cutter and related components, the device can perform cutting operations simultaneously or alternately, improving cutting efficiency. A fourth linear guide ensures the second cutter's precise positioning, coordinating with the first cutter to accommodate cutting needs of varying shapes and sizes. The dual-cutter design increases cutting flexibility. If one cutter malfunctions or requires maintenance, the other cutter can still maintain a certain level of progress, minimizing the impact on production.

[0018] Optionally, a first double-stroke cylinder is provided on the mounting frame, and the first double-stroke cylinder drives the first cylinder mounting plate to move along the setting direction of the third linear guide rail.

[0019] By adopting this technical solution, the first dual-stroke cylinder provides a more powerful and stable driving force, ensuring precise and smooth movement of the first cylinder mounting plate along the third linear guide, thereby improving the accuracy of the cutter positioning. The dual-stroke design increases the flexibility of the drive, allowing the appropriate stroke to be selected according to different cutting tasks and precision requirements, thus optimizing the cutting process. This helps to improve the response speed of the entire cutting assembly, shorten the cutting operation time, and thus improve production efficiency.

[0020] Optionally, a second double-stroke cylinder is provided on the mounting frame, and the second double-stroke cylinder drives the second cylinder mounting plate to move along the setting direction of the fourth linear guide rail.

[0021] By employing this technical solution, the second double-stroke cylinder provides stable and powerful power for the movement of the second cylinder mounting plate, ensuring that the second cutter can be accurately and quickly moved to the designated position along the fourth linear guide, improving cutting accuracy and efficiency. The double-stroke design allows for a more flexible and diverse range of movement for the second cylinder mounting plate, meeting more complex cutting needs and process requirements. In conjunction with the first double-stroke cylinder, the two cutters can be operated independently or in coordination, further enhancing the cutting capacity and applicability of the device.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. It can reduce the linear distance between the first material roll and the second material roll, reduce the amount of waste material after cutting, and improve material utilization.

[0024] 2. Through the synchronous or relative rotation of the two rotating disks, the cutting position and angle of the material strip between the two material rolls can be adjusted, which facilitates the cutting component to cut the material strip and improves the cutting efficiency.

[0025] 3. The sophisticated design of the pressing and cutting components effectively improves the cutting quality and product yield, adapts to the needs of high-speed cutting, and solves the problem of poor material tail processing in traditional cutting methods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] In this embodiment, referring to Figure 1-2 A material roll winding device that is convenient for cutting includes a mounting frame 1, on which is disposed a first rotating disk 2 that can rotate relative to the mounting frame 1, and on which is loaded a first material roll 3 that can rotate relative to the first rotating disk 2 to cooperate with the winding of the material strip. A second rotating disk 4 is also coaxially arranged on the first rotating disk 2, on which is loaded a second material roll 5 that can rotate relative to the second rotating disk 4 to cooperate with the winding of the material strip. This design allows the second rotating disk 4 to rotate synchronously with the first rotating disk 2, or the second rotating disk 4 to rotate independently relative to the first rotating disk 2, thereby adjusting the linear distance between the first material roll 3 and the second material roll 5. This structure not only simplifies the complexity of the device, but also improves the flexibility and precision of the cutting operation.

[0032] The operating principle of Example 1 is as follows: by controlling the relative motion of the first and second rotating disks 2 and 4, the linear distance between the two rolls can be precisely adjusted to accommodate the cutting requirements for different lengths of tails. Before cutting, the first and second rotating disks 2 and 4 rotate synchronously to adjust the cutting position and angle of the web between the first and second rolls 3 and 5, facilitating the cutting of the rolls by the cutting assembly 9. After cutting, the first roll 3 is used for normal rewinding, while the second roll 5 receives the cut tails. By optimizing the distance between the two, tail waste can be minimized.

[0033] Example 2

[0034] The difference of this embodiment is that the material roll winding device for facilitating cutting also includes two spaced-apart base plates 6, each of which is mounted with a first linear guide rail 7, and the entire mounting frame 1 is mounted on these two first linear guide rails 7. This design allows the mounting frame 1 to slide relative to the base plates 6, further enhancing the flexibility and adjustability of the device. By sliding the mounting frame 1, the position of the material roll can be easily adjusted to suit different production environments and cutting requirements. The installation of the first linear guide rail 7 on the mounting frame 1 not only provides a smooth sliding motion but also ensures the stability and precise positioning of the mounting frame 1 during movement. This design allows the operator to easily adjust the position of the material roll, thereby improving production efficiency and operational convenience.

[0035] Example 3

[0036] This embodiment goes a step further by adding adjustment screws to the base plate 6. These screws are used to adjust the height of the base plate 6 from the ground. Adjusting these screws ensures the device remains horizontal and stable in various operating environments, thereby improving cutting quality and the device's service life. The provision of these adjustment screws allows the device to adapt to various uneven ground conditions. Simply turning the screws allows for fine-tuning of the base plate 6's height, ensuring stability and precision during cutting.

[0037] Example 4

[0038] Based on Example 1, this embodiment introduces a pressing assembly 8. The pressing assembly 8 includes a second linear guide rail 81 mounted on the mounting frame 1, and a pressure roller 82 provided on this guide rail. The movement of the second linear guide rail 81 can drive the pressure roller 82 to move toward or away from the second material roll 5, thereby applying stable pressure to the material roll during the cutting process, ensuring the flatness and consistency of the cutting. The introduction of the pressing assembly 8 effectively solves the problem of possible movement or shaking of the material roll during the cutting process. The constant pressure applied to the second material roll 5 by the pressure roller 82 ensures that the cutting blade can contact the flat material surface every time it cuts, thereby significantly improving the cutting quality.

[0039] Example 5

[0040] Based on Example 1, this example introduces a cutting assembly 9. The cutting assembly 9 includes a third linear guide 91 disposed on the mounting frame 1. A first cylinder mounting plate 92 is provided on the third linear guide 91. A first drive cylinder 93 is provided on the first cylinder mounting plate 92. A first cutting blade 94 is provided on the first drive cylinder 93. The cutting assembly 96 also includes a fourth linear guide 96 disposed on the mounting frame 1. A second cylinder mounting plate 97 is provided on the fourth linear guide 96. A second drive cylinder 98 is provided on the second cylinder mounting plate 97. A second cutting blade 99 is provided on the second drive cylinder 98. A first two-stroke cylinder 95 is provided on the mounting frame 1. The first two-stroke cylinder 95 drives the first cylinder mounting plate 92 to move along the direction set by the third linear guide 91. A second two-stroke cylinder 910 is provided on the mounting frame 1. The second two-stroke cylinder 910 drives the second cylinder mounting plate 97 to move along the direction set by the fourth linear guide 96. The first linear guide rail 7 , the second linear guide rail 81 , the third linear guide rail 91 and the fourth linear guide rail 96 all include two parts: a slider and a guide rail, and the slider can slide on the guide rail.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
