[0002] With the continuous progress of battery technology and the reduction of costs, batteries (including lithium batteries, sodium batteries, etc.) are increasingly widely used in the new energy vehicle and household small appliance industries.

[0003] The safety of battery use is an issue that must be focused on. Because during the use of batteries, problems such as battery overheating, battery leakage, and battery fire may occur. Once these problems occur, they may pose a serious threat to property and even people's lives. Therefore, ensuring the safety of new energy batteries is very important.

[0004] A fireproof sticker is a sticker layer that can suppress the fire source. It can quickly release chemical purifying agents when a fire breaks out, thereby playing a role in suppressing the fire source, preventing and controlling fires. Now, many batteries use fireproof stickers to ensure that in the event of problems with the battery, the fire source can be quickly suppressed and the occurrence of safety accidents can be reduced. Fireproof stickers are usually prepared by rolling fireproof materials to obtain a basic fireproof layer. Therefore, the rolling process will have a greater impact on the performance of fireproof stickers, such as the flatness and firmness of fireproof stickers, thereby indirectly affecting the fireproof effect. Content of the Utility Model

The first direction is perpendicular to the second direction.

[0037] The rolling device 1 for preparing the fireproof sticker provided by the present application can save space by arranging the second transmission platform 3 at intervals above the first transmission platform 2, making the whole device more compact and suitable for installation and operation in a limited space. The design of the extension part 31 of the second transmission platform 3 enables the fireproof layer to be more smoothly guided into the rolling assembly 4, reducing the need for manual operation, improving the degree of automation and production efficiency. Corresponding the inlet end of the rolling assembly 4 with the outlet end of the first transmission platform 2 can ensure accurate alignment of the diaphragm layer and the fireproof layer when entering the rolling assembly 4, thereby improving the quality of the press forming.

Compared with the up-and-down pressing method, it can improve the flatness and firmness after pressing.

[0038] Specifically, the fireproof sticker roll formed by using this device needs to be pressed twice.
