A feeding pipe 51 is passed through the baffle plate 26, and a storage box 52 is provided on the baffle plate 26. The feed liquid rushes into the storage box 52 from the feeding pipe 51, pushing the second slide plate 57, so that the second spring 56 is compressed, and a first slide plate 53 is slidably connected in the storage box 52, and the position of the first slide plate 53 can be adjusted by rotating the handle 55, and a threaded rod 54 is provided at the upper end of the first slide plate 53, and the threaded rod 54 is threadedly connected to the storage box 52, and a handle 55 is provided at the upper end of the threaded rod 54.

The coating liquid can enter the storage box 52 by pushing the second slide plate 57 through the feed pipe 51. The second slide plate 57 is pushed to the discharge port 58 to expose the coating liquid, and the coating liquid can flow out of the storage box 52. At this time, By turning the handle 55 to press the rotating rod 34 downward, the first slide plate 53 slides in the storage box 52 and compresses the second spring 56. When the coating liquid pushes the second slide plate 57 with the same force, the exposed area of ​​the discharge port 58 will become smaller to change the amount of coating liquid flowing out. The power supply of the punching cylinder 62 is plugged in, and the punching cylinder 62 can drive the fixed frame 63 to move downward so that the punching die 67 punches the pole piece. When the punching die 67 needs to be replaced after being used for a period of time, the bolts 65 on both sides are rotated to make the bolts 65 disengage from the threaded groove 66, and the punching die 67 together with the sliding column 64 are directly removed.
