Cutting mechanism and feeding device

A feeding device for feeding and cutting a pole piece, comprising:

• a mounting base;
• a cutting mechanism mounted on the mounting base;
• and
• a guide mechanism;
• the cutting mechanism comprising:
• a cutter holder;
• a stationary cutter fixedly arranged on the cutter holder;
• a moving cutter assembly comprising a mounting piece and a moving cutter, the mounting piece slidably arranged on the cutter holder, the moving cutter mounted on the mounting piece, and the mounting piece having a centerline parallel to a direction of sliding of the mounting piece;
• and
• a driving assembly comprising a first end and a second end, the first end matched with the guide mechanism, and the second end connected to a part of the mounting piece corresponding to the centerline;
• wherein when the cutter holder drives parts located thereon to move, the guide mechanism can drive the driving assembly to apply a driving force to the mounting piece in the direction of sliding of the mounting piece, so that the mounting piece drives the moving cutter to move close to the stationary cutter so as to cut the pole piece at a preset position.
