The number of limiting plates 304 is two, and a connecting rod 305 is fixedly connected between the two limiting plates 304 and the two sliding seats 302. A second limiting component 4 is arranged on the left side of the two limiting plates 304, and a cooling device 5 is fixedly installed above the bottom plate 1. The cooling device 5 is specifically a spray cooling machine for cooling the battery diaphragm. A winding device 6 is arranged on the right side of the cooling device 5, and the winding device 6 is fixedly installed above the bottom plate 1. The winding device 6 is used to wind up the battery diaphragm.

[0024] When the above-mentioned device is used, the battery diaphragm is first passed through the two rotating rollers 202 and connected to the winding device 6. At this time, the winding device 6 and the cooling device 5 are started to wind the battery diaphragm while cooling it. During the winding process of the battery diaphragm, it will be between the two rotating rollers 202 and drive the rotating rollers 202 to rotate. At this time, the two sliding seats 302 are driven to slide in the same direction on the sliding bar 301 by rotating the bidirectional screw 303. The sliding seat 302 will drive the connecting rod 305 to make the two limit plates 304 approach each other on the rotating roller 202, so as to limit the space for the battery diaphragm to pass between the two rotating rollers 202, so that the battery diaphragm can maintain stable movement to prevent winding deviation.

[0025] Embodiment 2

[0026] See also Figure 1-Figure 4On the basis of the first embodiment, the second limiting component 4 includes a slide rail 401, which is fixedly connected to the left side of the support column 201, and a slider 402 is slidably connected to the left side of the slide rail 401. The slider 402 can only slide on the slide rail 401 and will not fall off the slide rail 401. A limiting plate 403 is fixedly connected to the left side of the slider 402. There are two limiting plates 403. A spring 404 is elastically connected between the two limiting plates 403. When the spring 404 is in a normal state, an elastic force is applied to keep the two limiting plates 403 away from each other. The second limiting component 4 also includes a push rod 405. The push rod 405 is L-shaped. The push rod 405 is fixedly connected to the right side of the limiting plate 304. The push rod 405 is fixedly connected to the upper and lower surfaces of the push rod 405 with guide plates 406.

Two guide plates 406 are arranged on a single push rod 405, and the two guide plates 406 form a V-shaped structure.

[0027] When the above-mentioned device is used in practice, the two limit plates 304 are moved closer to each other on the rotating roller 202, and the push rod 405 is also driven to move closer to each other. The push rod 405 drives the guide plate 406. At this time, as the guide plates 406 on the front and rear sides of the limit plate 403 move closer to each other, the guide plate 406 will make the two limit plates 403 move closer to each other. Therefore, when the limit plate 304 limits the passing space before and after the battery diaphragm, the upper and lower spaces of the battery diaphragm are also limited, so that the limit plate 403 cooperates with the limit plate 304 to form a channel, thereby facilitating the stable passage of the battery diaphragm.
