Abstract: Provided are a roller assembly, a battery cell manufacturing device, and an adjustment method of a roller, which relates to the field of battery manufacturing technology. The roller assembly includes a holder, a roller, and a first adjusting member. The roller is rotatably mounted on the holder. The first adjusting member is rotatably mounted on the holder, and one end of the roller is rotatably connected to the first adjusting member. A rotation axis of the roller does not coincide with a rotation axis of the first adjusting member. One end of the roller is rotatably mounted on the holder through the first adjusting member. The rotation axis of the first adjusting member does not coincide with the rotation axis of the roller, and therefore, rotation of the first adjusting member is capable of driving a corresponding end of the roller to rotate, thereby adjusting an extension direction of the roller.
