A spring 48 is arranged between the adjusting rod 46 and the supporting frame 1, and a rotation hole 451 is arranged in the middle of the connecting rod 45. The adjusting rod 46 is located under the unreeling roller 2 and the reeling roller 3, the adjusting rod 46 is rotationally connected with the supporting frame 1, and the reeling roller 3 is provided with a driving motor on the back of the supporting frame 1. Specifically, as the radius of the pole piece coil increases, if the transmission speed of the pole piece is unchanged, the surface tension of the pole piece becomes larger, otherwise, the surface tension of the pole piece becomes smaller; shortening the distance between the driven roller 43 and the fixed roller 51 can effectively reduce the tension in the pole piece transmission process, and otherwise, increases the tension. The sliding rail 41 in the tensioning mechanism 4 is fixed on the support frame 1, the rotating hole 451 arranged on the connecting rod 45 is in rotating connection with the support frame 1, and the rest of the tensioning mechanism 4 components are not contacted with the support frame 1; the adjusting rod 46 can always contact with the pole piece roll on the unreeling roller 2 and the reeling roller 3 under the action of the spring 48, and then the position of the driven roller 43 is changed through the conduction of the connecting rod 45, so that when the radius of the pole piece roll on the unreeling roller 2 is gradually reduced, the distance between the driven roller 43 and the fixed roller 51 can be slowly increased, and the tension of the pole piece roll in the cleaning process is ensured to be unchanged; when the radius of the pole piece roll on the winding roller 3 is gradually increased, the distance between the driven roller 43 and the fixed roller 51 can be slowly reduced so as to ensure that the tension of the pole piece roll can be kept unchanged in the pole piece recovery process; in this way, the tension of the pole piece coil is automatically and real-time adjusted. The fixed roller 51 is rotatably connected with the second roller 52, and the driven roller 43 is rotatably connected with the first roller 44; the arrangement of the first roller 44 and the second roller 52 enables the pole piece to pass through the rolling of the first roller 44 and the second roller 52 in the conveying process, so that the pole piece is smoother in the conveying process.

The spray head 68 is a high-pressure rotary spray head, and the spray head 68 is arranged at the upper and lower ends of the cover 61. The spraying mechanism 6 is also provided with a liquid storage tank, the cleaning liquid used by the spraying mechanism 6 is alcohol, and the spray head 68 and the drain pipe 66 are both communicated with the liquid storage tank so as to facilitate the cyclic utilization of the cleaning liquid after precipitation, thereby reducing the cleaning cost of the pole piece. The purpose of adopting alcohol as cleaning liquid is that: firstly, alcohol does not corrode electronic components, so that the pole piece is prevented from being corroded by cleaning liquid, and the quality of the pole piece is prevented from being damaged after cleaning; secondly, alcohol is very volatile and dries quickly, so that the drying time and the drying difficulty of the pole piece after cleaning can be effectively shortened, and the pole piece after cleaning can be quickly rolled up after being simply dried by the drying mechanism 7, so that the pole piece after cleaning can be conveniently transferred to the subsequent production process of the battery.

As shown in fig. 3, the transmission mechanism 5 includes a fixed roller 51 disposed on the support frame 1, a second roller 52 is sleeved outside the fixed roller 51, the second roller 52 is disposed to enable the pole piece to be in contact with the second roller 52 capable of rolling in the transmission process, and the fixed roller 51 is fixed, so that friction force of the pole piece in the transmission process can be effectively reduced, the pole piece is transmitted more rapidly, and abrasion of the pole piece in the transmission process is avoided.
