Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery technology, specifically to a lithium battery electrode rolling device. Background Technology
[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. They can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, the lithium metal battery, was developed in 1996. Its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to lithium-ion batteries. Due to its high technological requirements, only companies in a few countries produce this type of lithium metal battery.
[0003] A search revealed an existing patent (publication number: CN219903045U) that discloses a calender. This calender includes a frame, a calender roll assembly, and a oscillating mechanism mounted on the frame. The calender roll assembly includes a pressure roll, an intermediate roll, and a stripping roll arranged sequentially along the discharge direction. The pressure roll, intermediate roll, and stripping roll are rotatable relative to the frame. A first calendering gap exists between the pressure roll and the intermediate roll, and a second calendering gap exists between the intermediate roll and the stripping roll. The pressure roll can oscillate around the axis of the intermediate roll under the drive of the oscillating mechanism. This calender has a simple structure. During the calendering process, the oscillating mechanism drives the pressure roll to oscillate, adjusting the contact area between the film and the intermediate roll, thereby achieving the desired cooling effect for different films.
[0004] However, in the existing lithium battery electrode rolling equipment, the position of the rolling device is fixed during the rolling process. Therefore, when it is necessary to roll lithium battery electrodes of different lengths, the height of the electrode rolling device needs to be repeatedly adjusted, which will greatly reduce the practicality of the electrode rolling device.
[0005] Therefore, a lithium battery electrode rolling device is proposed to address the above problems. Utility Model Content
[0006] (a) Technical problems to be solved

Therefore, when rolling lithium battery electrodes of different lengths, the height of the electrode rolling device needs to be repeatedly adjusted, which greatly reduces the practicality of the electrode rolling device.

[0018] This invention provides a lithium battery electrode rolling device. It has the following advantages:

Under the action of the handle, the handle drives the rotating shaft a to rotate. The rotating shaft a drives the gear to rotate. The gear drives the rack to move. The rack drives the connecting block to move. In turn, the height of the rolling rod can be adjusted.

[0020] (2) The lithium battery electrode rolling device is equipped with an adjustment mechanism.

At the same time, the spring a can be prevented from shaking under the action of the sliding groove b and the slider b. Attached Figure Description

[0027] 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.
[0028] Please see Figure 1 Hezhi Figure 5 This utility model provides a technical solution: a lithium battery electrode rolling device, including a body 1, an adjustment mechanism 2 on one side of the body 1, an installation mechanism 3 on one side of the adjustment mechanism 2, and a storage mechanism 4 on one side of the adjustment mechanism 2. The storage mechanism 4 includes a bearing 401, which is disposed on one side of a connecting block 203. An installation ring 402 is disposed on one side of the bearing 401. A limit groove c403 is formed on the surface of the installation ring 402. A limit rod c404 is disposed inside the limit groove c403. A spring c405 is disposed on one side of the limit rod c404. A rotating shaft b406 is disposed on one side of the spring c405. A storage rod 407 is disposed on one side of the rotating shaft b406.
[0029] In the process of rolling lithium battery electrodes in the lithium battery electrode rolling device, by setting an adjustment mechanism 2, it is possible to avoid the situation where the position of the rolling device is fixed during the rolling process. Therefore, when it is necessary to roll lithium battery electrodes of different lengths, the height of the electrode rolling device needs to be repeatedly adjusted, which would greatly reduce the practicality of the electrode rolling device.
[0030] Please see Figure 2A lithium battery electrode rolling device includes an adjusting mechanism 2 comprising a slide groove a201 formed on the surface of a machine body 1. A slider a202 is disposed inside the slide groove a201. A connecting block 203 is disposed on the surface of the slider a202. A rack 204 is disposed on one side of the connecting block 203. A gear 205 is meshed with one side of the rack 204. A rotating shaft a206 is sleeved inside the gear 205. A handle 207 is disposed on one side of the rotating shaft a206. A limiting groove a2031 is formed on the surface of the connecting block 203. A limiting rod a2032 is disposed inside the limiting groove a2031. A slide groove b2033 is formed on the surface of the limiting rod a2032. A slider b2034 is disposed inside the slide groove b2033. A telescopic sleeve 2035 is disposed on the surface of the slider b2034. A spring a2036 is sleeved inside the telescopic sleeve 2035 and disposed on the surface of the machine body 1.
[0031] Specifically: During the rolling process of lithium battery electrodes in the lithium battery electrode rolling device, the handle 207 can be rotated first. Under the action of the handle 207, the rotating shaft a206 is rotated, the rotating shaft a206 rotates the gear 205, the gear 205 moves the rack 204, and the rack 204 moves the connecting block 203. This allows for height adjustment of the rolling rod 301, avoiding the inconsistency that occurs when the position of the rolling device is fixed during the rolling process of lithium battery electrodes. Therefore, when rolling lithium battery electrodes of different lengths is required... This would require repeated adjustments to the height of the electrode rolling device, which would significantly reduce its practicality. Furthermore, the sliding groove a201 and the slider a202 can limit the movement of the connecting block 203. The spring a2036 can be used to drive the limiting rod a2032 into the inner side of the limiting groove a2031, thereby fixing the position of the connecting block 203. At the same time, the sliding groove b2033 and the slider b2034 can prevent the spring a2036 from shaking.
[0032] Please see Figure 3 A lithium battery electrode rolling device, the mounting mechanism 3 includes a rolling rod 301, the rolling rod 301 is disposed inside the machine body 1, a rotating block 302 is disposed on one side of the rolling rod 301, a limiting groove b303 is formed on the surface of the rotating block 302, a limiting rod b304 is disposed inside the limiting groove b303, a spring b305 is disposed on one side of the limiting rod b304, and a connecting plate 306 is disposed on one side of the spring b305.
[0033] Specifically: During the rolling process of lithium battery electrodes in the lithium battery electrode rolling device, an installation mechanism 3 is provided. Under the action of spring b305, the spring b305 can drive the limiting rod b304 into the inner side of the limiting groove b303, so that the rolling rod 301 can be installed and replaced.
[0034] The working principle of this utility model is as follows: During the rolling process of lithium battery electrodes in the lithium battery electrode rolling device, the handle 207 can be rotated first. Under the action of the handle 207, the rotating shaft a206 is rotated. The rotating shaft a206 drives the gear 205 to rotate. The gear 205 drives the rack 204 to move. The rack 204 drives the connecting block 203 to move, thereby driving the rolling rod 301 to adjust its height. This avoids the need for repeated height adjustments of the electrode rolling device when rolling lithium battery electrodes of different lengths, as the position of the rolling device is always fixed during the rolling process. The practicality of the device is greatly reduced. Under the action of the slide groove a201 and the slider a202, the movement position of the connecting block 203 can be limited. Under the action of the extension and resetting of the spring a2036, the spring a2036 can drive the limiting rod a2032 into the inner side of the limiting groove a2031, thereby fixing the position of the connecting block 203. At the same time, under the action of the slide groove b2033 and the slider b2034, the spring a2036 can be prevented from shaking. Secondly, by setting the installation mechanism 3, under the action of the spring b305, the spring b305 can drive the limiting rod b304 into the inner side of the limiting groove b303, so that the rolling rod 301 can be installed and replaced.
