Recycling system and recycling method of positive pole piece

The invention relates to the technical field of pole piece recovery systems, in particular to a recovery system and a recovery method of a positive pole piece. The recovery system comprises a soaking device, a drying device, an extruding device, a screening device and a conveying device. And the soaking device is configured to soak the positive pole piece to remove the adhesive layer. And the drying device is configured to dry the positive pole piece soaked by the soaking device. The extrusion device comprises a first extrusion roller and a second extrusion roller, and knurling structures are arranged on the side face of the first extrusion roller and the side face of the second extrusion roller; a gap is formed between the side surface of the first extrusion roller and the side surface of the second extrusion roller, and the positive pole piece is extruded in the gap. The conveying device is configured to clamp the positive pole piece to sequentially pass through the soaking device and the drying device and
