Rollers are essential components of a winder, as multiple rollers are used for unwinding and aligning the positive and negative electrode sheet rolls, separator rolls, and tab rolls. However, during operation, the winder generates dust, such as carbon dust from the negative electrode material and other dust from the positive and negative electrode materials. This dust can interfere with the proper rolling of the rollers.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figures 1 to 2 FIG. 1 is a structural diagram of a roller structure with a dustproof function provided by an embodiment of the present invention, comprising:

[0023] Roller 3;

[0024] An end cover 2 is provided at the front end. A first gap 7 is provided between the end cover 2 and the roller 3. A first block 5 is provided on the end cover 2 and is located on the inner side of the roller 3. The bearing 4 is located on the side of the first block 5 away from the roller shaft 1.

[0025] The roller shaft 1 is disposed at the rear end, with a second gap 8 between the roller shaft 1 and the roller 3. A second block 6 is provided on the roller shaft 1, located inside the roller 3. Another bearing 4 is located on the side of the second block 6 closest to the roller shaft 1. In this embodiment, the first block 5 is integrally formed with the end cap 2, and the second block 6 is integrally formed with the roller shaft 1.

[0026] In one embodiment of the present invention, the roller structure with dustproof function addresses the problems in the prior art. At the front end, the roller shaft 1 extends a first block 5 to the inner side of the roller 3, and the bearing 4 is located on the side of the first block 5 away from the roller shaft 1. The first block 5 can prevent dust from entering the bearing 4 through the first gap 7 between the roller shaft 1 and the roller 3; at the rear end, the roller shaft 1 extends a second block 6 to the inner side of the roller 3, and the bearing 4 is located on the side of the second block 6 close to the roller shaft 1. The second block 6 can prevent dust from entering the bearing 4 through the second gap 8 between the roller shaft 1 and the roller 3;

[0027] The roller shaft 1 and the end cover 2 penetrate into the bearing position of the roller 3, and are blocked by the first block 5 and the second block 6 so that the dust on the roller 3 is prevented from falling into the bearing 4.

[0028] like Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, the end surface of the first blocking block 5 facing the first gap 7 is an inclined surface.

[0029] Setting the side surface of the first blocking block 5 facing the first gap 7 as an inclined surface can more effectively prevent dust from entering the bearing 4.

[0030] like Figure 2 As shown in FIG. 1 , as another preferred embodiment of the present invention, the end surface of the second blocking block 6 facing the second gap 8 is an inclined surface.

[0031] Setting the side surface of the second blocking block 6 facing the second gap 8 as an inclined surface can more effectively prevent dust from entering the bearing 4.

[0032] like Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, one side surface of the roller shaft 1 forming the second slit 8 is an inclined surface.

[0033] The side surface of the roller 3 forming the second gap 8 is set to be an inclined surface.
