The pole pieces to be dried are clamped below the sliding plate 6 by the clamp 7. After the pole pieces are fixed on the sliding plate 6, the sliding block 18 is driven to move by the feeding motor 19. The supporting rod 15 moves with the sliding block 18. When the arc-shaped part 17 of the supporting rod 15 reaches the position of the outermost lifting ring 10, the spring 13 returns to the natural state and pulls the lifting ring 10 to move close to the sliding plate 6. The threaded block 9 moves with the lifting ring 10, and the threaded block 9 moves close to the lead screw 3. After the threaded block 9 abuts against the lead screw 3, the threaded block 9 is screwed with the lead screw 3. The lead screw 3 is driven to rotate by the drying motor 5. When the lead screw 3 rotates, the threaded block 9 moves in the direction of the lead screw 3.

Each sliding plate 6 can be stacked at the position of the supporting rod 15. When the sliding plates 6 are stacked, the corresponding sliding block 18 is driven to move by the feeding motor 19 again. The lead screw 3 is driven to rotate in the reverse direction by the drying motor 5. The threaded block 9 is clamped on the lead screw 3 again, so that the pole pieces pass between the two air outlet discs 26 again to be dried. The device can adjust the distance between the adjacent pole pieces and make the pole pieces pass between the two air outlet discs 26 in sequence to be dried quickly. A plurality of pole pieces can be dried at one time, so that the drying efficiency of the pole pieces is greatly improved.
